U.S.
Department of Health and Human Services
Advisory Committee on Organ Transplantation (ACOT)
Summary
Notes from Meeting
Washington, D.C.
May 6–7, 2004
Welcome and Update
Nancy
Ascher and Jack Kress
Nancy
Ascher started by saying that she looks forward to the important
contributions this committee makes to the arena of organ transplantation.
The outcome of this meeting will be guidance and direction
to the subcommittees to be the basis of recommendations they
will generate for the November meeting. She said that she
does not anticipate any recommendations being developed at
this meeting.
She introduced
Jim Burdick, the director of the Division of Transplantation,
who was standing in for Michelle Snyder, the Associate Administrator
of HRSA. Burdick commented on an important upcoming transition:
Jack Kress, the executive director of ACOT, is moving on this
summer to a study assignment under the aegis of HRSA at the
Albany Medical College in New York State. He pointed out some
of the highlights of Kress's tenure with the U.S. Department
of Health and Human Services (HHS) as he worked on legal and
ethical matters. Most significantly to ACOT, Kress was involved
in developing the early structure of ACOT and its processes.
He saw to the development of all of its recommendations, which
he then shepherded through the department. He has facilitated
progress after recommendations have been approved. In every
way, he has been a major factor and supporter in our efforts.
Burdick presented Kress with a Special Acts Award and certificate
to recognize his dedicated service to ACOT.
Burdick
went on to introduce the new executive director of ACOT—Thom
Balbier—who has worked at HHS since 1977, primarily
in the area of scientific and governmental aspects of vaccine
programs. Balbier briefly addressed the group, saying that
he was looking forward to working in this important field
and meeting the committee members.
Kress
thanked the participants and the audience. He noted that he
has a long history in the Albany area and looks forward to
returning to research. He plans to continue to work on organ
donation reform and improvements. He plans to start by learning
what happens at the ground level. He expressed his thanks
to the ACOT members. He noted that there will be a long transition
period during which he and Balbier will overlap to ensure
that ACOT's efforts will continue seamlessly.
He then
introduced the next item on the agenda—tissue and body
part concerns—noting that this topic has grown out of
two developments: (1) the efforts of former ACOT member Margaret
Coolican, who pushed us into the realm of tissue and body
parts; and (2) recent events and adverse publicity in that
field, which may affect organ donation. We need to ask about
what we need to do in this area.
Panel
on Tissue and Body Parts Concerns
Moderator:
Michael Seely
Panelists: Todd R. Olson, Hon. Margaret W. Henbest, Ronn Wade
Michael
Seely thanked the committee for including this topic, which
was brought to light by the media. It has had top billing
in many large media outlets. The integrity of the national
organ transplant system is at stake. We have not spent much
time on other forms of donation, but we need to consider these
issues. Currently, the federal regulatory framework does not
represent a consistent approach. Certain aspects of tissue
recovery and handling are subject to inspection by the Centers
for Medicare & Medicaid Services (CMS), and other aspects
are subject only to a voluntary accreditation process. Whole
body donation and use is largely unregulated, although there
may be rules and guidelines for oversight within institutions.
Margaret
Coolican was motivated to bring this issue to the attention
of Kress who in turn directed the issue to the attention of
this subcommittee. The fact is that there are many more tissue
donors than organ donors every year. Tens of thousands of
lives are benefited by tissue donation. Whole body donation
is also significant. Any single event in any of these arenas
affects the others. The public does not distinguish among
these different areas.
Todd
R. Olson
Albert
Einstein College of Medicine
Seely
introduced Todd R. Olson, who runs the Anatomical Gift Program
at the Albert Einstein College of Medicine in the Bronx, New
York, and who is also a council member of the American Association
of Clinical Anatomists. He has received wide press lately
as he has been speaking out against the practices that led
to recent scandals in willed body and tissue donation programs.
Olson
opened by saying that anatomists and the transplant community
have mutual concerns: "For the past 30 years, our two
fields have walked parallel paths, but our interests and differences
are intertwined: Our differences are far more significant
in our eyes than they are in the public's." He stated
that many of his anatomical colleagues have called him to
say they have been waiting for 20 years to gain a place in
this forum.
He noted
that the public lacks even a basic understanding of the distinctions
among the different types of donation. We are all educators
in respect to organ, tissue, and whole body donation. Public
education and education of the media are key roles. He made
a special request of the media representatives present at
the meeting to tell the "good parts of the story."
In the
absence of education, Olson continued, donation scandals will
likely diminish public confidence in all types of donation.
If it affects one school, it affects all. To ferret out the
wrongdoers, it is necessary to follow the money. He specifically
mentioned the scandals at the University of California-Los
Angeles, Tulane University, University of California-Irvine
and others that have been featured in recent headlines.
He noted
that really there is nothing shocking or surprising going
on. If anything, these events must be called predictable.
These situations arise when people of limited means decide
to ignore professional responsibilities and institutional
trust for personal gain. Where does the money come from to
motivate this behavior? Ultimately, Olson said, it comes down
to "Physician, heal thyself."
Physicians
themselves and professional societies need to step up and
say that they care. They are obligated to require detailed
oversight and accounting for materials used in educational
programs. Ethical practices in patient care do not cease with
the final breath; the need to respect the human body is at
the center of the doctor-patient relationship. "As anatomists,"
Olson said, "we are doing a great deal. We work with
willed-body programs so that those who convey material from
place to place are acting in concert with donor's wishes."
He mentioned some specific legislative and institutional efforts
in Texas, California, New York State, and at the University
of Pittsburgh School of Medicine aimed at reviewing or regulating
willed-body and tissue donation programs. He referred to several
articles on the topic.1, 2,
3, 4, 5
Olson
also spoke about the return of the resurrectionists (grave
robbers). He mentioned a recent article in Harper's Magazine
about modern-day resurrectionists6
and related the story of William Burke and William Hare who
went on a killing spree out of greed in Scotland in the 1800s.
Their activities were perpetrated against the citizens of
Edinburgh where Hare owned a boarding house. One of his pensioners
died, still owing 4 pounds in rent. Hare enlisted the help
of another resident—Burke—and took the remains
to a disreputable anatomist who paid them 7 pounds. Thus was
initiated the monetary motivation to kill pensioners for money.
Needless to say, there was great public concern and riots.
In New York, the militia had to be called out under similar
circumstances.
Those
who had teaching materials (i.e., body parts) were able to
run anatomy schools. The anatomists did not ask where the
materials came from, and this is the story happening again
today. Modern-day resurrectionists deal with donors who are
making donations that can save lives. What is needed is a
clear paper trail for body parts being used in education.
Olson
offered several recommendations:
- Expand
public education.
- Encourage
information sharing regarding tissues, organs, and body
parts.
- Approve
changes to the Uniform Anatomical Gift Act to deal with
the rapidly expanding body parts industry.
- Establish
a national central clearinghouse for parts used in anatomical
research that can serve as a go-between for sites of access
and sites of need.
- Insist
that organizations involved in oversight and regulation
of tissue banks approve only appropriate and legal uses
of bodies, body parts, and tissues.
- Ethical
considerations must extend to the remains of those who have
given to promote medicine.
Olson
urged those in attendance not to let this issue go away without
taking constructive action, saying, "This controversy
will come to your doorstep as well."
Hon.
Margaret Henbest
Idaho
House of Representatives
Seely
then introduced Representative Margaret Henbest from Idaho.
She has served in the Idaho state legislature for 8 years.
She is working to help the public understand what donation
is about. She is also a pediatric nurse practitioner and has
a particular interest in disclosure issues.
Henbest
said that she became aware of controversy surrounding body
donation about 6 years ago when she was contacted by a constituent
who was monitoring the activity of a county coroner. Coroners
are elected officials in Idaho and are not held to any standards.
Two-thirds of Idaho's coroners are funeral directors. The
constituent said that the coroner was involved in a business
enterprise that was harvesting heart valves. There were legal
and ethical concerns, and yet there were no laws that prohibited
this practice.
She spoke
about the experience of another constituent who was distraught
about the organ donation surrounding the death of his daughter.
The daughter had indicated prior to her death that she was
willing to donate her organs, and her family wished to honor
that wish. They discovered, however, that her long bones had
also been procured. The family had no idea that the donation
would include other tissues. They were left with unresolved
grief.
Subsequently,
Henbest did some research on tissue donation, storage, and
the profitability of organ and tissue transplantation. She
learned about the fact that the regulations governing organ
donation differ significantly from those addressing tissue
donation. She noted some specific concerns:
- Inadequate
regulation of the tissue industry that could lead to disease
transmission.
- Inadequate
registration of those who handle body parts: In 1998, the
requirement for registration were removed by Idaho's Department
of Health and Welfare. There was no punishment for not registering.
- Extreme
profitability of this industry: We must follow the money.
- Inadequate
requirements for informed consent: Consent is not exclusively
for organs, but for tissues, as well.
- Regulatory
loopholes that allow profiteering for use of body parts
research and education: There is concern because current
regulations are silent on the use of body parts for research
and education as opposed to transplantation, which is regulated.
Idaho
rewrote the state's Anatomical Gift Act. The goal was to provide
higher standards for informed consent. Henbest observed that
now, "when you apply for a driver's license in Idaho,
you receive a detailed brochure about how your body parts
might be used, and you are advised about available resources
and your rights. You can designate the exact purposes for
the use of your body, tissues, and parts. Parallel information
is given to families. Because we have elevated the degree
of consent, we are moving toward direct consent. Donation
rates have increased in our state." She noted that it
is important for people to know the uses of their donated
bodies. Therefore, Idaho has taken the law another step: to
add a preferred designation for for-profit or not-for-profit
use of the individual's body.
According
to Henbest, forthcoming legislative sessions will address
mandatory accreditation of tissue banks, as well as for-profit
tissue and body part programs. She said that we need federal
regulation so that the country does not end up with a patchwork
approach. We did not anticipate all the uses for tissues and
body parts when 40 years ago we drafted the Uniform Anatomical
Gift Act (UAGA). She also mentioned a recent poll in England
that indicated that the public is reluctant to have their
DNA used in research. Another issue at the fore has been military
use of bodies for testing artillery.
Henbest
concluded by saying that a high tide floats all ships. We
must remember this adage because the public does not differentiate.
We cannot be silent any longer.
Barry
Kahan asked Henbest about what types of donation have increased
in Idaho since the institution of better conformed consent.
Henbest replied that they have a database but have not drilled
down yet to see which types of donations are increasing. She
noted, however, that 15% more people have indicated via the
Department of Motor Vehicles (DMV) their willingness to be
a donor. Seely said that this more complex approach to consent
might have decreased donations, but such is not the case apparently.
Kahan observed that, in general, the more information you
give people, the less likely they are to read it or to sign
it. Henbest replied that she does not know whether people
are reading the brochure cover to cover, but it has not been
a barrier to donation.
Olson
was asked about what has happened with anatomical donation
in New York State since recent events. He noted that donors
fall into two different profiles. Some donors do so out of
humanitarian and altruistic motivation in gratitude for medical
care and to advance science. The second type of donors—a
significant number—donate for financial reasons. They
are seeking a way around funeral costs. Some people are donating
because they want to give money to their children. He observed
that they are receiving more interest from people who now
recognize the value of their bodies.
Henbest
volunteered to provide copies of Idaho's organ donation brochure
and informed consent form to ACOT. She also indicated a willingness
to work on getting more data on the effects of the new legislation
on donation rates.
Michael
Williams mentioned an article he reviewed for Critical Care
Medicine that dealt with the notion of desecration. Social,
personal, and religious overtones are there. We
must not forget the role of religious and faith communities.
Henbest agreed that those issues constitute the underpinning
for this discussion. The public is outraged when these issues
come to light. We must also address the enticement of profitability.
To build enough groundswell and interest, we must act in partnership
with religious organizations.
Olson
concurred with Henbest's comments, saying that transparency
is the key. We must emphasize education and disclosure.
Ronald
S. Wade
Maryland
State Anatomy Board
Ronald
Wade has directed Maryland's body donation program for 30
years. Wade noted that as organ transplants have became more
successful, people had that alternative to consider. When
he came on board, one of the first things he did was try to
reorganize so that body donation became more acceptable. Historically,
most bodies for study were unclaimed bodies or from tuberculosis
sanitariums, but now people want to leave a legacy by improving
medical care for the next generation.
Surgical
study labs were set up for training physicians, shock-trauma
personnel, emergency medical technicians, military medics,
and others. The number of bodies used in gross anatomy is
less than 300. The cause of death is not important; the donation
will not be refused. "We stand by our promise to accept
the donation."
The study
of anatomy has changed. Courses are shorter, and some courses
are doing away with dissection altogether, but there is a
continuing and increasing need to enhance surgical training.
To meet the need for training material, a whole gamut of body
brokers and for-profit tissue banks has sprung up.
Wade said
that he dealt yesterday with a university in the Midwest about
a push to obtain body parts from a broker. The bodies are
being obtained in the south. The State of Maryland will assist
with transferring remains out of state, but the transfer must
be through an institution.
It is
illegal to function as a broker or deal with a broker in Maryland.
Without requirements for serological testing, proper facilities,
and a social and medical history, dealing with bodies and
body parts is a high-risk situation. In Maryland, no surgical
conferences may be held in hotels or conference centers to
prevent disease transmission. Some brokers are going to funeral
directors who receive finder's fees. They may even pay for
use of a funeral home facility. These practices raise ethical
concerns. Wade deals only institution to institution to eliminate
brokers. He has a duty to the public, citizens, and the medical
community to ensure that everything is done to high standards
in compliance with public policy and with respect for donors
and their families.
Carlton
Young commented that this situation appears to be an exploding
problem. He expressed concern about desecration-denigrating
human bodies to the level of commodities. He noted
that the transplant community is always battling over the
issue of valuable consideration. How can we modify the UAGA
to raise the standard?
Wade said
that the legal value of a body is zero dollars. For example,
it is impossible to insure bodily remains for transportation.
Many people in Maryland carry organ donor cards or kidney
cards. He used to conduct surveys of donors. People are aware.
People are commonsensical. It is a changing culture. There
is a real need in medical schools for anatomical study materials.
Olson
observed that this is an international issue. Brokers can
work together with funeral directors. European doctors have
indicated that they acquire body parts from the United States,
Romania, and elsewhere. Trade appears to go the other way
as well. We need tracking systems across borders.
Wade said
that uniform donor laws are being framed to have parameters
for minimal standards. Regulations differ from state to state
presently.
Young
asked how we can support these efforts to modify the UAGA.
Kress said that ACOT has done so in the past and will do so
again. We need only to decide which subcommittee is the most
appropriate for this work.
Susan
Gunderson said that she knows little about whole body donation
even though she runs an organ procurement organization (OPO).
She continued, "We have come to understand tissue donation.
We have our heads in the sand if we think we are immune from
the fallout from unethical and illegal practices in willed-body
programs."
Kathy
Turrisi suggested that perhaps ACOT needs to branch out and
encompass these other areas that impact organ donation. Perhaps
we need to rethink our very name, which presently refers only
to "organ transplantation."
A
New Way of Looking at the Problem: The Burden of Disease and
Its Progression
Lawrence
G. Hunsicker
Henry Krakauer
Kress
presented Lawrence Hunsicker, a former ACOT member who is
also a past president of the United Network for Organ Sharing
(UNOS) and the American Society of Transplantation. He is
here today primarily because he is chair of the UNOS Data
Working Group. Hunsicker has been investigating the burden
of disease from a statistical point of view. Also involved
in this research are Henry Krakauer, an epidemiologist, and
Monica Lin, a statistician. They will describe an intriguing
new way of looking at the quality of life.
Hunsicker
noted that the Data Working Group (DWG) was created by the
Division of Transplantation to coordinate between the Scientific
Registry of Transplant Recipients (SRTR) and the Organ Procurement
and Transplantation Network (OPTN) to make sure that the right
data are collected in appropriate and efficient ways. The
DWG is advisory to UNOS and the scientific committee of SRTR.
Analysis
of transplant outcomes has so far focused on time to death
and time to graft loss. Although these are clearly important
outcomes, with improving patient and graft survival they are
no longer the only relevant outcomes to consider. Hunsicker
reviewed some reasons why it is not sufficient to consider
only graft and overall survival. For these reasons, ACOT has
charged the DWG with looking into quality of life issues.
The term
quality of life (QOL) is not a standard or well-understood
concept. There is a rationale for a new approach. For example,
there is a strong likelihood that alternative outcomes such
as morbidity and functional status will be highly correlated
with mortality risk. Cumulative morbidity and functional status
can be measured on many occasions and may offer greater statistical
power in analyses. Time-series analyses on nonterminal outcomes
may permit early intervention on high-risk patients.
Many years
of work led by Henry Krakauer has resulted in the identification
of five domains or dimensions of transplant outcomes that
constitute the burden of illness. They are:
- Mortality
- Cumulative
morbidity (adverse medical events, including graft loss
and other events, primarily evidenced at least initially
by hospitalizations)
- Disability/functional
status (ability to perform functions required/desired in
daily life)
- Psychological
distress (e.g., depression, anxiety)
- Resource
use (effort/resources needed to care for the patient, again
focusing initially on hospitalization).
Hunsicker
explained for each of the five proposed domains the existing
data sources, and he proposed some additional sources.
Mortality
Data on
mortality are now captured by the OPTN/UNOS system and are
supplemented by death data from the Social Security Master
File or National Death Index. These data are quite complete.
Cumulative
Morbidity
At least
initially, this domain would be evidenced by hospitalization
data. Limited hospitalization data are now collected on transplant
recipients. The new forms will ask post-transplant patients
about all hospitalizations since last reports. UNOS/OPTN collects
no data about waiting-list patient hospitalizations. CMS collects
complete data on kidney candidates and recipients who have
Medicare primary coverage. As a starter, the DWG has obtained
consent from Pennsylvania and Virginia to get comprehensive
hospitalization data on transplant candidates and recipients
from those states. Transplant centers do not have these data.
Functional
Status
UNOS/OPTN
collects functional status information on transplant recipients
at transplant and on follow-up forms, but for transplant candidates,
the data on functional status is collected only at the time
of registration. Although these data correlate with outcomes,
the grading is not sufficiently granular to capture less-than-gross
loss of function. Nevertheless, these data may be useful because
they are highly predictive of mortality.
The DWG
proposes to capture additional information on functional status
in a pilot study using the SF36 physical status scale and
replacing the current UNOS functional scale (The New York
Heart Scale — four points) on the transplant form with
the Karnofsky Index. The Karnofsky Index (Figure
1) represents 11 levels of function ranging from normal
to minor impairments that do not adversely affect function
to a moribund state to death. It is the standard, best validated
objective scale for functional status, and it can be completed
at the time of patient clinic visits in less than one minute.
This proposal
was discussed at the Data Advisory Committee meeting in late
April. This will not be an effortless change. Someone will
have to collect the data and complete the scale during clinic
visits. Vanderbilt University has been acquiring Karnofsky
data for some time.

Psychological
Distress
Presently,
no data are collected by UNOS/OPTN on this domain. The DWG
proposes to collect this information from the SF-36 mental
health subscale. This instrument is widely used to assess
mental and psychological status.
Resource
Use
UNOS/OPTN
currently collects no data on this domain, although NOTA charged
OPTN and SRTR with collecting financial data on the costs
of transplants. At least initially, the DWG proposes to focus
on hospitalization resource use by estimating from hospitalization
data the effort needed to care for the patient. The basis
will be uniform coding based on DRG weights and length of
stay.
For which
patients do we need to track these five domains? The benefit
of the transplant is the total difference between projected
outcomes based on whether the transplant is performed or not
performed. In addition, we should think about including those
who are not transplanted but live with chronic disease. That
issue, however, is outside the scope of today's discussion.
Hunsicker
made it clear that there is no intent for the proposed analyses
to force any particular approach to the formulation of deceased
donor organ allocation or other UNOS/OPTN policy. The proposed
approach to analysis will simply inform UNOS/OPTN committees
more broadly about the outcomes of transplantation. The Board
and the Committees are free to use the information as they
deem appropriate.
To what
extent will these domains correlate with morbidity and mortality?
It is conceivable that many patients who receive lung transplants,
for example, do not have longer lives but their QOL post-transplant
may be very much greater. In any event, a person who is considering
a lung transplant may wish to look at the impact of transplant
on survival and functional status. The best approach for analysis,
then, may be combination of multiple outcomes in a model with
a multivariate outcome. That is, outcomes in all five domains
can be considered as a single vector (per individual). In
this approach, the mutual correlations among the outcomes
are observed directly (as the covariance matrix) in the analysis.
This approach is objective and leaves weighting to policy
makers and patients.
Using
combined analysis of multiple outcomes may be leading the
way for the rest of the health community, but it is not a
slam-dunk. Not all groups may wish to pursue this line of
thinking. Others may wish to work out different approaches.
Let many investigators look at these data using different
analytic approaches.
In addition,
different analysts may have different goals. Some may strive
to optimize use of limited resources (organs or funds); others
may seek to optimize outcomes for a particular patient.
Analyzing
Multiple Outcomes for Transplant Candidates and Recipients
Robert
Wolfe
The Data
Advisory Committee is looking at several different mathematical
approaches, according to Robert Wolfe. We are looking at the
benefit of transplantation although it involves many different
outcomes. Wolfe listed two rate measures (mortality, hospitalization)
and four scaled measures (days in hospital, resource use,
functional status, and psychological distress). Scaled measures
are determined at different points in time and then the averages
are weighted.
Wolfe
also said that analyses will continue to be done as they always
have been; the multiple outcomes model will be an addition.
Traditional methods for modeling combined outcomes are based
on the following tenets:
- Outcomes
are often correlated. Patients high on one outcome might
be high on another.
- Correlation
can arise from shared measured characteristics: Covariates
predict multiple outcomes. For example, diabetics have both
high hospitalization and high death rates.
- Correlation
can be modeled with regression: One outcome predicts another.
For example, mortality can be predicted by recent hospitalization
and recent low functional status.
Wolfe
highlighted two innovative methods for analyzing correlated
outcomes. First, frailty models introduce a patient specific
covariate to account for correlation. Frailty is an unmeasured
covariate that predicts the outcomes of interest (rates or
means). The frailty for each patient is imputed to fit the
outcomes for that patient. Second, Bailey, Krakauer, and Lin
have developed an innovative method to analyze correlated
outcomes.
Modeling
the Components of the Burden of Disease
R.
Clifton Bailey
Clifton
Bailey said that an analytical plan is needed for collecting
and analyzing data. We have chosen to use each component as
a cumulative measure, but the problem remains of how to put
the measures together. A probability summary is a consistent
way of dealing with these outcomes — morbidity, mortality,
and resource use. We use mathematical representations to capture
the essence of these components (domains). It is necessary
to deal with the correlations conjointly.
He showed
several graphs, including the declining hazard pattern of
post-transplant mortality. The risk of dying is very high
immediately after a procedure, and then the risk declines.
Post-listing mortality has a different pattern of increasing
hazard. The post-transplant morbidity curve rises and then
falls.
When modeling,
they make use of the explanatory variables that they want
to model. Morbidity and resource use could be modeled in any
of several different ways. In every case they have used the
cumulative distribution form. Each of those, in turn, is made
to depend on these explanatory factors. Therefore, the correlations
output by the model will be case-specific. For example, they
may arrive at one set of correlations for diabetics and another
set for nondiabetics.
Trivariate
Multiple Outcomes Model
Monica
Lin
Monica
Lin discussed how data were developed for applying the trivariate,
multiple outcomes model. The focus has been on the post-transplant
period. The data set is based on a cohort of Medicare-eligible
patients listed in 1996 and followed until the end of 2000.
Transplants are included only if they occurred prior to 2000
(minimum of 1 year of post-transplant follow-up. Data sources
are:
- OPTN:
Data on patient characteristics at listing and transplant,
and on disability (from the follow-up form).
- USRDS:
Data on hospitalizations from consolidated OPTN and Medicare
data (sole source on experience on dialysis).
- Medicare:
SS Death Master File. Data on hospitalizations (morbidity
and resource use).
The model
may provide an evidence-based, objective answer to the question
posed by many patients, "What will happen to me?"
Estimates are made by simultaneously modeling survival, resource
use, and morbidity.
Among
the questions that the model could address include these:
- Benefit:
What is the outcome for the average patient with and without
transplant?
- Subgroups:
What differences are there among different patient subgroups?
- Policy
1: Which patient currently on the list is likely to
benefit most from receiving this organ?
- Policy
2: How would outcomes be changed by proposed policy
changes?
- Individuals
within subgroups: How much variation is there among
individuals?
- Correlation:
Are the individuals who are at high risk for one outcome
also at high risk for other outcomes?
The DWG
is continuing work on simultaneously modeling of four outcomes
and is also looking into waitlist outcomes. A paper has been
submitted to the American Journal of Transplantation.
Some discussion
ensued. Hunsicker made a point about distinguishing between
policy formulation and the personal decisions made by patients
and their doctors. OPTN focuses on policy, but ACOT may wish
to take a broader view to reflect patients' preferences. Discussions
about possible outcomes occur all the time between transplant
surgeons and their patients, but there have not been any data
to inform these discussions. These data allow the patient
to make decisions about the tradeoffs involved.
According
to Hunsicker, the Data Advisory Committee (DAC) was concerned
about the additional burden on transplant centers that would
result if the Karnofsky Index were adopted, although the vote
was 18-2 in favor of adopting the Karnofsky index. DAC proposed
a pilot study for collecting SF-36 data that would involve
random sampling with oversampling of certain subgroups. Centers
will not need to get separate Investigative Review Board (IRB)
approvals.
Nancy
Ascher asked if the analysis takes into account a center effect.
She suggested simplifying the language describing the model
and she recommended that in order for patients to weigh risk
and benefit, the center effect becomes paramount.
Hunsicker replied that the model is not intended to look at
center effect. He agreed that the model might be improved
by incorporating center effects.
Barry
Kahan said that it could be an onerous task to collect data.
He asked if it would be possible to go to a pharmaceutical
company and test some of the hypotheses with data that have
already been collected on existing cohorts.
Hunsicker
replied that the only burden will be associated with the letters
and consent forms patients receive regarding the Karnofsky
index. Some patients will ask about the letter they will receive.
The consent letters will be very detailed. He also said that
in regard to conducting a retrospective study that the existing
cohorts are not very standard.
Kahan
said that in virtually every clinical study, we have already
collected Karnofsky and SF-36 data. We could set up two study
arms and test the models.
Hans Sollinger
noted that clinical practice is evolving very quickly. We
have learned how to deal with extended donors. We can almost
equalize outcomes using various protocols to conserve kidney
function. It is a challenge to keep up with these radical
changes in our clinical approaches. Looking at retrospective
data would be a useful scholarly practice, but to base clinical
decisions on old data could be perilous.
Flora
Solarz said that with the growing waitlist, we do not know
what outcomes we are promising our patients. We need to look
at this seriously and weigh the ethical implications. We talk
much about informing patients and that is what this discussion
is really all about. Resource use seems parallel to hospitalization.
It may be more useful to consider resource utilization
by the patients than by the hospitals. Another
danger is that predictions about hospitalizations could raise
the eyebrows of insurance companies when they decide who will
be transplanted.
Hunsicker
(to Sollinger) said that collecting the data does not necessarily
mean that a recommendation will flow from it. The present
is always different from the past, but we cannot just throw
away those data. We are always better off knowing something
than not knowing something. Regarding Solarz's comments, he
said that it would be very useful to know something about
the individual's costs in terms of resource utilization, but
we have to look at the costs we can get at more easily.
Kathy
Turrisi noted that, in the past, staff at the center were
the ones who completed the Karnofsky or SF-36 forms. It would
be more useful if the patients themselves were asked for their
input on the forms. Hunsicker replied that the plan is to
mail out the full SF-36 forms to the patients because the
centers do not necessarily know how the patients are doing.
The Karnofsky Index would be done by the centers. We will
have to carry out a fair bit of education to get the forms
filled out correctly.
Young
urged caution because if we hone things down too precisely,
we may think we know what's best. If the model outcomes are
memorialized as policy, might patients be denied transplant
because of the potential for poor outcomes due to their race,
co-morbidities, or other factors? It could get so burdensome
that we will not transplant because of potential risks. We
must be very careful because the data could be misused.
Michael
Williams expressed reservations about using specific percentages
in patient discussions. These are just probabilities. We need
to present data in useful ways. Trouble arises when patients
are promised specific outcomes. It is best to say that we
will try our very best, but here are the risks.
Hunsicker
said that having the data would help inform these discussions.
For example, with livers we have found that the sickest patients
are not futile transplants; this is the group that actually
receives the most benefit from transplantation.
Robert
Gibbons congratulated the group for looking at a broader field
of outcomes. We are already using statistical models albeit
inefficient ones for making transplant decisions. For example,
the Model for End-stage Liver Disease (MELD) is based on a
univariate model. We need to continue in this path to look
at multivariate outcomes.
Amadeo
Marcos said that we cannot continue using only patient and
graft survival as outcome measures. The issue is to do what
is best for patients. What is the weight that will be given
to each factor? Policy decisions will continue to be made
by the various appropriate committees of OPTN.
Three
Decades of Struggles and Triumphs: Reflections on 30-Plus
Years of Transplantation
Clive
O. Callender
Clive
Callender is the founder and head of the Minority Organ and
Tissue Transplantation Program (MOTTEP). He has performed
more than 300 kidney transplants. He left Minnesota in 1973
and started the program at Howard University. He shared some
of his ideas and thoughts as he reflected back on his 30-year
career.
Callender
identified 14 critical issues facing the transplantation community:
- Organ
donor/organ recipient disparity: As of January 2004,
this disparity represents 60,000 people. More than 16 people
die daily because of the organ donor shortage. Callender
said that the situation seemed hopeless when he started
because African Americans used to donate organs at lower
rates than other ethnicities because of many factors. This
trend, however, has changed. Minorities, who represent 25%
of the American population, made up 15% of donors in 1990
but comprised 28.5% of donors in 2000. In 1990 the organ
donor/million rate for Blacks was 22.4; in 2000 it had risen
to 40.8.
- The
Green Screen: The Green Screen is a symbol for the
lack of dollars or medical insurance or the ability to pay
for health care or the medication necessary to sustain the
health provided by transplantation. African Americans constituted
only 10% of those waiting for livers in 1995, yet African
Americans die more frequently of liver failure than do Whites.
"If you didn't have the green, you couldn't get on
the waitlist and you would die." The role of the Green
Screen in renal transplantation is undefined, but it must
exist because people are denied transplants due to a lack
of means to pay for post-transplant immunosuppressive therapy.
Callender mentioned the film "John Q." The Green
Screen is underappreciated as an obstacle to transplantation.
We are all accountable because we won't approve the taxes
necessary to pay for transplants for those of limited means.
- Prevalence
and incidence rates for kidney failure in Blacks (African
Americans) and other minorities: The incidence and
prevalence rates of end-stage renal disease (ESRD) for Blacks
(African Americans) and other minorities are disproportionately
high because of their increased susceptibility to diabetes
and hypertension (twice that of Caucasians).
- Disproportionate
effect of human immunodeficiency virus (HIV) on Blacks (African
Americans) when compared to Caucasians: It is not clear
why the nephropathy of HIV is so largely a problem of African
Americans. Blacks (African Americans) with HIV experience
HIV nephropathy at 10 times the rate of other ethnic groups.
In fact, 93% of all AIDS nephropathy cases reported are
in African Americans.
- Dialysis
survival rates for Blacks: Blacks have patient survival
rates on dialysis that are superior to Caucasians. Callender
discussed some data regarding 1-year and 2-year mortality
rates of African American and Caucasian ESRD patients on
dialysis, showing that African Americans do much better
on dialysis than do Caucasians, but is this good news or
bad news? The USRDS report demonstrated that healthier blacks
remain on dialysis whereas healthier whites are transplanted.
This is really a negative data item. We cannot compare until
transplantation rates are equalized.
- Race
and science: Callender emphasized the need for completely
replacing the term "race" with the word "ethnicity"
in science. The human genome mapping project demonstrated
conclusively that all humankind, Homo sapiens, belongs to
one race. This finding once and for all makes it clear that
in science the issue of race is an illusion that must be
done away with. Using "race" is divisive and renews
the sociopolitical construct that denies the positive aspects
of each ethnic group and reenergizes the superior/inferior
designation. We are all one race with different ethnicities.
This change must occur throughout the scientific community,
the U.S. Census Bureau, and the Office of Management and
Budget, until the term "race" is replaced by ethnicity
in all scientific journals and census data.
- Compliance
rates for Blacks: Blacks and Latinos are no more noncompliant
than other ethnic groups. The groups that are least compliant
are adolescents and health care professionals!
- Unique
post-transplantation drug responses in African Americans
(Blacks): Blacks after transplantation metabolize transplant
medications differently than Caucasians and other ethnic
groups, thereby altering their responsiveness to these medications.
One of the reasons is that Blacks are more immunoresponsive
than other ethnicities. One study showed that 90% of African
Americans were hyperimmune in contrast to 66% of Caucasians
when pre-transplant immune responsiveness is studied. Therefore,
it is clear that Blacks require more powerful immunosuppressive
therapy than other ethnicities. In addition, cyclosporine
is poorly absorbed in Blacks. Prednisone's side effects
(hypertension, diabetes, and obesity) tend to be especially
problematic for African Americans. Blacks have to pay more
to get effective doses of Cellcept because the effective
dose for African Americans is higher than for Caucasians.
In many instances, gastrointestinal and bone marrow intolerance
are problematic for African Americans. The necessity of
using lower doses may increase the likelihood of acute rejection
episodes. Tacrolimus — one of the most potent immunosuppressants
— is associated with the development of posttransplant
diabetes at twice the rate in African Americans and Latinos
than when it is used in Caucasians. In addition, development
of insulin dependence tends to be permanent in African Americans
in contrast to the situation with Latinos and Caucasians
who generally experience reversible insulin dependence.
Part of the reason may lie in genetic differences in the
P450 cytochrome oxidase system or in the higher level of
immune responsiveness of African Americans. Elucidation
of this enigma may improve graft survival for African Americans.
- Delayed
transplantation referrals for Blacks and other minority
patients: Blacks are referred later for kidney transplants,
are placed on the waitlist later, and are transplanted later
than Caucasians, regardless of financial status. Callender
referred to the work of Alexander and Sehgal7
who objectified and, for the first time, put in print what
had been suspected for some time: Blacks, women, and poor
people encounter barriers to transplantation. Danovitch,
Cohen, and Smits8 propose
using the European (Eurotransplant) model, which defines
waiting time as beginning when the patient begins hemodialysis
in an uninterrupted fashion. This simple change would level
the playing field in regard to delayed referral times for
African American transplant candidates.
- Waiting
times for Blacks and other minorities in transplantation:
Waiting times for kidneys are twice as long for Blacks and
other minorities as for Whites. A study by Roberts et al.9
shows that we have made some improvements in transplantation
rates for Blacks, but we still have a long way to go.
- The
fate of kidneys and other organs transplanted into Blacks:
African Americans after transplantation of kidneys and other
organs have 10% to 20% poorer graft survival rates than
all other ethnic groups (at 2–5 years after transplantation).
This trend is evident whether the organ was recovered from
a living related donor, living unrelated donor, or a deceased
donor. Why is not known. In 1977 Opelz et al.10
first reported that kidney donor and graft survival rates
in African Americans were the poorest among all ethnic groups.
A subsequent analysis of the OPTN/UNOS database showed that
Black recipients of deceased donor or living donor kidneys
were associated with statistically significantly poorer
graft survival regardless of donor ethnicity. Black recipients
of deceased livers and hearts had significantly lower graft
survival rates when receiving organs from Whites, Blacks,
or Latinos. The reasons for these ethnic differences are
unknown. When looking into half lives for kidney transplants
across all ethnic groups, it can be seen that Asians have
the most favorable half lives and African Americans have
the shortest half-lives (living or deceased donor transplants).
It had been hoped that increasing the numbers of black donors
would increase graft survival, but that may not be true.
Many hypotheses have been offered and disproven (e.g., too
few black donors, HLA mismatch, inequitable distribution).
The negative correlation of hypertension, hyperimmune responsiveness,
and institutional racism seem clear. Why hypertension is
such a highly negative correlate remains a mystery and should
be a focal point for research and study. The newest immunosuppressive
regimens may provide some answers. The most hopeful and
most correctable problem is institutional racism. There
is a need for changing lifestyles and thereby reducing the
need for organ transplantation. MOTTEP is already addressing
this.
- The
fate of donated African American kidneys and other organs:
When African American organs are transplanted into African
Americans or Caucasians, they have significantly inferior
graft survival. Black to black donation has the highest
relative risk of graft loss (kidney or liver). African American
kidney donors survive for shorter periods than all other
ethnicities. It would be inappropriate to recommend, however,
that all organs donated by African Americans should be considered
high risk. The data reflect the need for more research.
We do not understand the reasons for the graft survival
disparity, nor do we have a strategy to overcome this.
- Inequitable
allocation schema: Inequitable, discriminatory allocations
were the consequence of HLA antigen matching at the A and
B loci. The work of Roberts et al. was instrumental in ending
a system that was ethnically discriminatory to Blacks since
1989. UNOS abolished antigen matching at the HLA-A locus
by 1994 and the B locus by 2002. Eliminating these criteria
has increased public trust in the donation and allocation
processes.
- The
effects of institutionalized racism: Deep-rooted conscious
or subconscious classifications of ethnic groups into superior
and inferior classes may be the most important obstacle
to overcome to eliminate transplant health disparities.
"Institutionalized racism" is a term that is unrecognized
in the field of ESRD or transplantation. To say it is taboo
is an understatement. Yet, as we look at the disparities
discussed previously, it appears that few items are as pervasive
or as understudied as the phenomenon in this field. The
human genome project has made it clear that we are all the
same species, yet this insidious attitude persists. The
pathophysiologic consequences of institutionalized racism
have been demonstrated by Jules Harrell11
and others since 1982. Institutional racism is likely responsible
for the longer waiting times for Blacks compared to Whites
for kidney transplantation, delayed referral of Blacks for
kidney transplantation, Blacks receiving kidney transplants
later than Whites, and Blacks being referred later, if at
all, for extrarenal transplants.
Callender
recommended the following actions for eliminating ethnic disparities:
- Provide
adequate funding for further research into the 14 highlighted
areas.
- Allocate
an additional $200 million to the National Center on Minority
Health and Health Disparities to address research questions
and help eliminate the disparities in transplantation and
donation.
- Eliminate
the word "race" and replace it with the term "ethnicity"
in the science and health arena and in the federal government.
- Develop
a national strategic plan with goals and implementation
dates with a community-based effort to eliminate institutionalized
racism by educating and empowering the minority and majority
communities.
- Encourage
the involvement of the minority communities in health prevention
activities to help ameliorate the need for organ transplantation.
- Develop
an empowered minority community and enlist its support in
changing behavior that fosters institutionalized racism.
William
Harmon noted that one of ACOT's first recommendations to the
Secretary was to support research into ethnic disparities.
Turrisi
said that, in Charleston, it has been her experience that
many African Americans have not been managed aggressively
for hypertension and diabetes. That may be an early factor.
We are starting to look at those disparities. Callender observed
that we are not treating post-transplant hypertension properly
either. Right now we have abject ignorance. We need a strategic
plan to address it.
Roger
Evans asked why Callender is using the word "disparities"
instead of "inequities." Callender said that it
is the same thing. Evans replied that the word "inequities"
implies a cause. Disparities is just politically correct.
We all want all Americans to have successful transplants.
What helps one group helps the others.
Fritz
Port made the point that three disadvantaged antigens
are more common in the African Americans than in Whites. When
we combine dialysis and transplantation and adjust for diabetes,
hypertension, and age, we find that blacks have better outcomes.
It is a profound observation, which we need to analyze further.
Recent
Congressional Action
Emily
Marcus Levine
The Organ
Donation and Recovery Improvement Act (formerly the Frist
Bill, now Public Law 108-216, an amendment of the National
Organ Transplant Act (NOTA) passed Congress overwhelmingly
and was signed into law by the President on April 5, 2004.
The Act
expands the Secretary's authority to improve donation and
transplant system and symbolizes Congress's recognition of
the importance of these issues.
Section
3 of the Act may be of particular interest to ACOT. By way
of background, Section 301 of NOTA makes it illegal for any
person to "...knowingly acquire, receive, or otherwise
transfer any human organ for valuable consideration..."
Statutory exclusions include "...expenses of travel,
housing, and lost wages incurred by the donor of a human organ
in connection with the donation of the organ." The Organ
Donation and Recovery Improvement Act authorizes the U.S.
Department of Health and Human Services (HHS) to disburse
grants ($5 million per year for 2005–2009) to reimburse
living donors for allowed expenses. This is payment of last
resort. The Secretary may also pay such expenses for up to
two people to assist the donor. Preference is to be extended
to people whom the Secretary determines are least likely to
otherwise meet expenses.
Section
4 deals with public awareness; studies and demonstrations.
This section establishes new grant/contract authorities and
provides for a public awareness program to be overseen by
the Secretary directly or administered through grants/contracts.
This section also addresses the need to educate the public
and generate awareness about the need for donors. Some programs
already exist, but this provision will be supplementary. Also
included in this section is authority for issuing peer-reviewed
grants/contracts with the intent to conduct studies and demonstration
projects for both deceased and living donors.
Section
4 also gives new authority to issue grants to OPOs and hospitals
(must be trauma hospitals and those serving populations of
200,000 people) for the purpose of establishing programs to
coordinate organ donation activities to increase donation
rates. This measure will help states in their efforts to increase
donation. Finally, there is an educational activity section.
HHS will develop educational materials to inform health care
and other professionals on donation issues. These programs
must coordinate with OPTN and other organizations.
Section
5 confers new authority on the Secretary, through the Agency
for Healthcare Research and Quality, to develop scientific
evidence in support of efforts to increase donation and improve
the recovery, preservation, and transportation of organs.
The Secretary is authorized to conduct or support research,
carry out a review of the scientific literature, develop and
adopt proven practices. Other activities mentioned include
research and dissemination of findings, development of a uniform
clinical vocabulary for organ recovery and so forth, enhancement
of skills in the workforce, and assessment of technologies.
Section
6 directs the Secretary to report to Congress on transplant-related
activities under NOTA. The report is to discuss which activities
have affected rates of organ donation and recovery and must
include an analysis to evaluate the effectiveness of activities.
The practices to be covered are to include those of the states,
organizations, and other countries. The initial report is
due in 2005, and subsequent reports every 2 years thereafter.
The 2005 report must:
- Address
donation practices for most effective practices and existing
barriers
- Evaluate
living donation practices
- Evaluate
federally supported and conducted efforts
- Evaluate
state registries
- Include
a plan to improve federally supported and conducted activities.
Section
7 authorizes the Secretary to establish and maintain mechanisms
to evaluate the long-term effects associated with living organ
donation.
Section
8 is likely to involve ACOT in meaningful ways. This section
directs the Secretary to evaluate proposals to increase cadaveric
donation and report to Congress on those proposals. The Secretary
must consult with the community (advocacy groups representing
populations likely to be disproportionately affected by proposals).
The report is due by 12/31/2004. Kress noted that there is
likely to be a role for ACOT in the development of this report,
which he referred to as the "Section 8 Study." He
reminded the group that this meeting will result in direction
and guidance to the Subcommittees. The recommendations coming
out of the November meeting will then have to be addressed
quickly in order to roll those recommendations into the Section
8 Study.
Section
9 repeals section 371(a)(3) of the Public Health Service Act
(part of NOTA), which gave grant/contract authority for special
projects designed to increase the number of donors. It had
been relied upon by HRSA's Division of Transplantation but
has now been replaced with more expansive authorities and
a larger pool of eligible entities.
Levine
noted that the new law does not address the controversial
valuable consideration issues under section 301, nor does
it appropriate any funds. (Funds were only authorized.) Language
was struck from Frist's original bill about demonstration
projects to test incentives that otherwise might be barred
under NOTA section 301.
Progress
Report on the HHS Breakthrough Collaborative and the Latest
Secretarial Organ Initiative
Dennis
Wagner
Virginia McBride
Dennis
Wagner told the story of the Breakthough Collaborative and
shared the broad outline of the YIELD initiative, which is
aimed at increasing the number of organs transplanted per
donor.
The Organ
Donation Breakthrough Collaborative is "committed to
saving or enhancing thousands of lives a year by spreading
known best practices to the Nation's largest hospitals to
achieve organ donation rates of 75% or higher in these hospitals."
Wagner noted that the involvement of the Joint Commission
on Accreditation of Healthcare Organizations (JCAHO) in the
Collaborative is largely due to ACOT's work.
A collaborative
is an intensive, full-court press to facilitate breakthrough
transformations in the performance of organizations, based
on what already works. The methodology can be implemented
in a variety of issues and arenas. In particular, the goals
of the Organ Donation Breakthrough Collaborative are to:
- Increase
the average conversion rate of eligible donors from the
current average of 43 percent to 75 percent in the Nation's
300 largest hospitals
- Increase
donations by up to 1,900 donors per year
- Increase
the number of transplantations by 6,000 per year
- Help
save the lives of thousands of people each year and prevent
up to 17 deaths per day.
Wagner
noted that 50% of eligible deceased donors are found in 223
hospitals; 90% are found in 953 hospitals. When one examines
1-year conversion rates among the largest 300 hospitals, conversion
rates range from 10% to more than 90%. Most cluster around
the national average of 40% to 50%.
The Collaborative
has conducted site visits at six top-performing OPOs to develop
a menu of practices that generate high conversion rates. Wagner
showed a slide of conversion rates by donation service area
(DSA). The average rate goes from more than 80% to 30% or
less. This is not a case of being clumped around the average.
The Collaborative
team consists of about 500 people at 95 large hospitals and
42 organ procurement organizations. The faculty includes 13
leading practitioners from OPOs and hospitals that have high
conversion rates. Also, a leadership coordinating council
supports the Collaborative. (Several council members were
present in the room, including several members of ACOT.)
The Collaborative
functions within a framework of learning sessions. Learning
Session 1 (LS1) is dedicated to the study of change concepts
and the Deming PDSA model (Plan, Do, Study, Act). LS2 encompasses
more PDSA cycles. LS3 is dedicated to sustaining progress.
The LS4 meeting will probably be held in November. Each team
reports monthly. The learning sessions were also broadcast
via satellite to large hospitals across the county to enable
remote participation.
Susan
Gunderson shared some of her insights gained as a result of
her experience with the Collaborative. She said it has been
very helpful to get hospital people together with OPOs so
we are looking at the common problem and seeing how we can
work together. The other real benefit is information sharing.
The information is really used to bring about practice change.
It is timely and helpful. She also spoke about the benefits
gained by bringing the other players to the table (e.g., JCAHO,
American Hospital Association) to hear their views on organ
donation. She admitted that the Collaborative is an enormous
amount of work.
Michael
Williams spoke about attending the first Collaborative: "We
learned that our effort was designed to bring together transplant
coordinators, nurses, and physicians to work together."
He cautioned, however, that it may be difficult to isolate
effects of the Collaborative versus other interventions, perhaps
confounding data collection and analysis for other studies.
Mike Seely
said that the energy generated by the Collaborative is infectious.
"Everyone is coming together to solve problems."
He attended the learning session in Dallas and was struck
by the size of the group. He observed that, historically,
all these groups have been working in silos. "It is an
eye-opening experience for OPOs to be at a table with their
hospital peers." The Collaborative makes very effective
use of the open space technique.
Virginia
McBride then spoke about the results of the Collaborative's
Action Period 2. She noted that the Collaborative in many
respects carries out Acot Recommendations 12-16. Specifically,
for example, ACOT's recommendation 16 states that "the
regulatory framework provided by the Center for Medicare &
Medicaid Services (CMS) for transplant center and OPO certification
should be based on principles of continuous quality improvement.
The Collaborative's work is not research. It is indeed continuous
quality improvement.
The Collaborative
has a few process measures:
- Timely
notification within 1 hour of a mutually established clinical
trigger over the number of imminent deaths, expressed as
percentage. The clinical trigger could be, for example,
a Glasgow Coma Scale of 4 or a determination that care has
become futile.
- Appropriate
requester. The number of cases in which a designated requester
met with families over the total number of requests made,
expressed as a percentage. We have found that it is not
a matter of who makes the request but that the family has
received information and support so that they are comfortable
with the decision when that time comes.
McBride
showed a graph (Figure 2) of these process
measures. Timely notification among Collaborative members
is up to about 80%; the appropriate requester rate is up to
about 90%.
D
The bottom
line metric is the conversion rate, defined as organ donors
over eligible donors, expressed as a percentage. Stated otherwise,
the conversion rate represents consented donors from whom
an organ is recovered for the purpose of transplantation including
non-heartbeating donors and donors over the age of 70. This
measure is not about OPO performance. This measure reflects
how well hospitals are setting up donation situations. Conversion
rates bounced around. We need to get a conversion rate above
62% to see a statistically significant difference as a result
of the Collaborative.
Some Collaborative
teams achieve 75% conversion rates during some months, but
we need to get more teams to that level. October set the record;
January broke the record for organ donations.
McBride
listed Collaborative hospitals with 75% conversion rates.
She mentioned the achievements of St. Joseph's Medical Center
in particular.
D
D
McBride
described a new metric for the Collaborative — the number
of donors before a non-donor — that is, the frequency
with which successful donation events are interspersed with
unsuccessful events. This measure is intended to help teams
recognize when they are maximizing successful donation events.
The goal is to keep a string of donors going.
The theme
of LS3 was, "What does your team need to do to get to
75%?" Teams must reduce the number of non-consents. This
must be a team focus for testing and changes. The number of
non-consents has not changed much. To change consent rates,
the system must change. McBride identified some high-leverage
changes that have been implemented by successful teams:
- Use
a synergistic combination of strategies to get to 75%.
- Acknowledge
organ donation advocacy as an appropriate family support
objective.
- Seamlessly
integrate OPO and hospital roles and responsibilities (ACOT's
Recommendation 13).
- Capitalize
on the strengths of an integrated and flexible organ donation
team.
- Follow
early referral with rapid response (ACOT's Recommendation
15).
- Establish
and manage an effective requesting process.
For every
learning session, the Collaborative identifies teams that
are succeeding. Then film crews are deployed to document those
practices. A set of about 20 videos is available now to be
used as resources for participants to bring back to their
home hospitals.
Wagner
spoke about the strategies being developed to spread Collaborative
successes. He identified two key aspects of spread strategy
development:
- Get
results from this collaborative.
- Create
and nurture the infrastructure and support network for extending
the momentum of the collaborative.
Key elements
of the spread strategy include:
- Sustaining
support for current teams through the third action period
and the fourth learning session.
- Supporting
the leadership coordinating council.
- Conducting
a learning session in September 2004 to bring in 200 new
organizations which will overlap with the first collaborative
so there is a mentorship opportunity.
- Supporting
a network of spread leaders.
- Building
and operating a knowledge management system.
- Making
learning sessions available via satellite.
- Conducting
a "National Learning Congress."
The Collaborative
is ready to spread information on mutual accountability, the
75% conversion rate target, the model for improvement and
small testing cycles for achieving changes, process measure
improvement, and high-leverage changes that generate team
conversion rates greater than 65%. Wagner cited the success
of the Collaborative's work on donation after cardiac death
(ACOT's Recommendation 13). Results were achieved quickly.
After the learning sessions, hospitals went back and immediately
formulated policy and got their first DCD donors during that
cycle.
He also
spoke about the YIELD initiative and its goal of achieving
an average of 3.75 organs transplanted from every donor. He
identified two strategic aspects of the Collaborative's work
to increase yield:
- Improved
use of technology
- More
knowledge about practices already in use to achieve higher
yields and then promotion of those practices.
Key audiences
for the YIELD initiative are OPOs, transplant surgeons/physicians,
and the critical care/intensivist community. The initiative's
timing is opportune. The Secretary is strongly behind this
initiative, which builds upon the momentum and national learning
community generated by the Collaborative. Technology is available
to support the initiative, and leadership organizations are
already on board.
The Collaborative
plans to implement a study to identify best practices of those
who have high yields and involve key practitioners in the
study. An expert panel of practitioners will be convened to
vet and refine study findings. A HRSA/UNOS technology summit
will be convened to review and refine performance guidelines
for technological improvements. Data, practices, and the summit
findings will be used to inform guideline development.
Wagner
asked the group for insights and ideas about the Collaborative's
spread strategy and YIELD Initiative. Sollinger said that
the Collaborative is the most exciting thing in this field.
He appreciates that it is designed to measure success. He
suggested, however, forming a task force to see why these
big centers are not big producers.
Ascher
said that she receives a "report card" every 6 months
about how her center is doing, and how its affiliates are
doing. "Donation Dashboards" were distributed to
show where their numbers were.
Harmon
said that being a good organ donor hospital could be a public
relations nightmare. It may be a dubious distinction to be
the best organ donor hospital. Gunderson said that they do
recognize their top donor hospitals. The hospitals were pleased
and proud that they offer this service to families.
Williams
said that it is important for physicians to talk through their
feelings of failure and improving donation rates. He emphasized
the difference between a values-based approach for making
changes versus the compliance-based approach. People become
resistant to change with the compliance-based approach. People
must want to make the change.
Gibbons
asked how hospitals were selected for the Collaborative. Wagner
responded that two key criteria were involved: They had to
be large hospitals and they had to demonstrate a high level
of commitment.
Gibbons
made several suggestions about improving data analysis. He
suggested that using a method to show cumulative changes will
be much more likely to show positive effects. Use methods
designed to show trends. Model the factors that work together
to improve rates. Use strengths to focus efforts. Others involved
in the Collaborative emphasized that the function is not to
demonstrate statistical differences but to identify and implement
best practices.
Kahan
noted that if a patient in the emergency department appears
to be indigent, there may be a reluctance to intubate the
patient and transfer him or her to the intensive care unit
because if the patient does not become a donor, the hospital
is stuck with the charges.
One participant
said that it is unusual for large transplant centers to be
major donor centers. It seems to be a conflict of interest.
If the transplant folks support the donation piece, it is
problematic. Williams responded that it is necessary to have
firm, written policies for determining brain death. There
has to be a separation between those who determine brain death
and those involved in donation. There are easy ways to handle
the conflict of interest. You need the right people.
Delmonico
asked if a definition of eligible donors has emerged. There
may be fewer brain death diagnoses being made. McBride said
that they have a definition that is consistent with the OPTN's
definition. Through the Collaborative, the number of eligible
donors has increased. Kahan said that is very interesting.
Some of us in the field think the opposite. This clearly deserves
appropriate scientific study. We need to look at that carefully.
If the minority of our donors progress to become brain dead
donors, we need to know that.
ACOT
Valuable Consideration Subcommittee (A)

Presumed
Consent
Phil Berry
led a discussion of this topic. He is himself a liver recipient.
Over the last several years, he has begun speaking out about
organ donation. He has been frustrated by the length of the
waiting list, which has more than 80,000 people on it now.
He has been frustrated by seeing so many good people trying
to do good things. The gap is growing because the length of
the waitlist is far outstripping the number of organs donated.
An article 12 was circulated
among the Subcommittee members about an opt-out, presumed
consent system. Berry said that the more you ask people to
do, the less compliance you will get. The systems that tend
to work are the ones in which people don't have to do something.
The article described the results of an online survey conducted
via email.
Berry
compared opt-in and opt-out systems: In an opt-in system,
if you fail to sign an organ donor card, the default is that
no organs are taken upon your death. In an opt-out system,
the default is that you will be an organ donor unless you
have taken action to indicate that you do not wish to become
an organ donor. According to the article, the survey indicated
that the effective consent rate under an opt-in system would
be 42%. Under an opt-out system, the effective consent rate
would be 82%. Eighteen percent indicated that they would opt
out of being an organ donor. It was an interesting study.
These data and those of Gimbel suggest that a change in our
default would provide thousands of organs each year. The consequences
would be powerful. Defaults do make a difference.
In summary,
Berry urged the group to continue to look at every avenue
we have to increase organ donation. We cannot continue beating
our heads against the wall. We must consider an opt-out system.
The American Medical Association held an ethical discussion
around incentives for donors. We don't know, but we need a
demonstration project to study the effect of financial incentives
to find an answer. Demonstration projects could be undertaken
by states that have an interest in doing this. We could encourage
those that are willing to try. We should commit to it for
a year or two or three. I hope we are open enough that we
don't keep thinking that more education, or this or that,
will make a difference. Nothing is changing the path we are
on.
Barry
Kahan made that point that, in Spain, they still ask family
permission and do not go against the family's wishes. He asked
Berry to summarize what is going on in Texas where there was
an attempt to get the legislature to endorse presumed consent.
Berry
said that Spain attributes their high organ recovery rates
primarily to having in-house OPOs. In Houston, there is a
close alliance with OPOs in-house to ensure that organs "do
not fall through the cracks." Houston is one of the top
five procurers in the country. The number one recommendation
is that we should try presumed consent. He doubts that more
than 2% of the legislators read the report because of a lack
of interest. It would behoove us to revitalize that report.
California has talked about a bill to introduce presumed consent.
Gail Agrawal
asked about what points the Subcommittee should present to
ACOT. What are the responses we can anticipate? What are the
legal impediments as to the ability of a state to enact legislation
to allow presumed consent?
Emily
Marcus-Levine said that there is no federal bar. There are
some cases where the family is deemed to have a property right
in the body. There may need to be a legal process to deal
with that, but there is a need to protect constitutional rights.
Ronn Wade
said that, according to common law, the primary right of disposition
belongs to the next of kin. The only way that the family right
can be overcome is through a will. The other way around it
is eminent domain — the right of the state. This approach
was tried in Pennsylvania and also failed in Maryland. There
was a view that the state would be trespassing over the family
rights.
Susan
Gunderson asked if we are talking about organs, tissue, research,
body parts. We need a long timeline.
Agrawal
said that we need to present some questions before the full
committee. We are not making a specific proposal. We need
to generate the information we need so we have information
to work with. This is a process.
Nancy
Ascher said that we may be suggesting two demonstration projects
that are in opposition to each other. Kahan said that once
you offer an incentive to one group, it changes the other
group's attitude toward purely altruistic donation. The last
time the National Kidney Foundation discussed this, it was
thought that those who were disadvantaged may be less likely
to opt out. To meet constitutional challenges, it would have
to be clear that there are surefire ways to record opt-outs.
Someone
else raised the freedom of religion issue. Even though no
major religion objects to organ donation, constitutional issues
remain.
One participant
suggested using the word "tacit" instead of "presumed."
Perhaps attach the language "to save a life." Gimbel's
research showed that 19 countries have presumed consent, but
several do not enforce it. Can we talk to some doctors from
those countries to see what the barrier is?
Kahan
mentioned a recent article by Islamic scholars that emphasize
the role of organ donation in saving lives. Not all countries
enforce the donor's wishes over the family's because of public
concerns, the possibility of improper notification, and so
forth. Someone else mentioned the example of Singapore and
events that occurred after presumed consent was enacted there.
Three
years' lead time would probably be a good interval to allow
for public education before enforcing presumed consent.
Roger
Evans said that we are working with outdated information.
Many people now know someone who has had a transplant. Attitudes
may have changed.
Ronn Wade
discussed an attempt to get the Maryland General Assembly
to pass something. Eye banks may take tissue from any medical
examiner cases. One particular group is those who are on life
support. He mentioned required request laws.
Ascher
suggested asking ACOT to endorse a proposal for developing
a template for presumed consent. Then, as part of that, actually
make contact with state representatives to see where we could
get a groundswell of interest and support.
Kahan
suggested surveying other countries to see why this concept
didn't hold and see if we can avoid their problems.
Berry
suggested this terminology: "Presumed consent: A way
to save lives." He recommended sticking with the phrase
"presumed consent" because it is embedded in the
literature now.
Mary Ganikos
said that the survey DOT is preparing will probably go out
in 4 months. It is in the OMB pipeline. It includes questions
on organ donation and presumed consent. Some items will be
duplicated from the old 1993 survey so we can track those
indicators. There may be a question to see if there is a difference
between organs and tissues. The draft survey had been sent
to the committee some time ago.
Valuable
Consideration—Preferred Status
Josh McGowan
presented some information from the SRTR data report related
to preferred status granted to living organ donors. He reminded
the group that NOTA prohibits the exchange of valuable consideration
in connection with organ procurement or transplantation.
The goal
of the data analysis was to quantify the impact of previous
(living kidney) donation on waiting time for transplant candidates
relative to cohorts in similar time periods and locations.
The analysis
included all waitlist registrations for a deceased donor,
kidney-alone transplant between 1/1/1993 and 12/31/2002. Waitlist
registrants in this study cohort were stratified (grouped)
according to previous living donor status. In order to determine
a candidate's status, SRTR screened patients that were identified
as being a previous living donor in the SRTR kidney candidate
data file. They also investigated whether or not four waiting-time
points were awarded during an attempt to match a candidate
with an available organ as stated in the OPTN Deceased Donor
Kidney Allocation Rule. Because not all candidates that were
identified as previous living donors were awarded waiting
time points, they separated "potential" previous
living donor waitlist registrations into two separate groups
as shown in Table 1.

Registrants, 1993-2002 (n=197,137)

197,047 |
For all
waitlist registrations identified in this analysis, a Cox
Proportional Hazards model was used to estimate the time until
50% of all registrations received a transplant (median time
to transplant). The model was adjusted for the following candidate
factors: blood type, age, gender, race, type of insurance,
peak PRA (indicates level of sensitization to donor antigens),
status as a previous transplant recipient, waitlist year and
location (Donor Service Area [DSA]; previously referred to
as OPO). Waiting time was calculated as the number of days
after waitlist registration until removal from the waitlist.
Reasons for removal include recovery from illness, receiving
a transplant, transferring to another center or dying while
on the waitlist.
The results
in Table 2 show that the median time
to transplant for waitlist registrations that were identified
as having previous living donor status and awarded four waiting
time points was estimated to be 499 days (1.37 years; adjusted).
However, for registrations not identified as having previous
living donor status, the median time to transplant was estimated
to be 1,115 days (3.05 years; adjusted).

The potential
benefit of a shorter time to transplant may vary for candidates
according to geographic region (DSA). As indicated in Table
3, 28 DSAs had an estimated median time to transplant
of less than 886 days (2.43 years; adjusted) during the study
period. However, there was a difference of 731 days in median
time to transplant (2.00 years; adjusted) for the 28 DSAs
between the 25th and 75th percentiles.

McGowan
noted that some 40 patients were noted as being living donors
but had not received the four-point preference. He was not
sure why that happened.
He concluded
by saying that the median time to transplant for waitlist
registrations with previous living donor status (1993-2002)
was estimated to be 499 days (1.37 years) compared to a median
time of 1,115 days (3.05 years) for registrations that were
not a previous living donor. Therefore, 50% of previous living
donor registrants were transplanted in an estimated 616 fewer
days (1.69 years). However, the absolute value of the waiting
time reduction is likely to vary substantially by where (geographically)
the candidate is registered on a transplant waiting list (DSA).
Median times to transplant during this period varied more
than eightfold between the 5th and 95th percentile of DSAs.
It appears,
then, that a waiting time advantage has been provided to kidney
transplant candidates who are awarded four points for being
a previous living donor. He also noted that the allocation
rule was recently modified to provide a greater advantage
by giving candidates who are awarded four points top local
priority for kidneys that are not shared as a 0-HLA mismatch.
Kahan
said that his impression is that the four points is not conferring
a very great benefit. Living donors should perhaps be awarded
six or eight points. The benefit could be extended to family
members on a one-time basis. Merion said that four points
does not mean a great deal in many areas. Kahan asked if it
would be possible to give them more points. Merion said that
such an approach is basically planned obsolescence. The aim
of the OPTN board was to give them ultimate priority after
children, 0-HLA mismatch, and presensitized individuals. How
often are they preempted? Kahan said that if we are talking
valuable consideration without involving money, maybe we should
give preference on waitlist to the family. Emily Marcus Levine
said that such a system would raise ethical questions because
it could be coercive for those considering donating loved
ones' organs. Also, counsel has not issued an opinion about
the four points given for living donation. We do not want
the Secretary to be pursuing an illegal course.
Jim Burdick
said that Levine's point has not been addressed. We don't
know that the points are valuable consideration. How do the
points work? It is complicated. They are getting four years'
waiting time credit. They may be using their points to stay
on the waitlist and avoid using extended-criteria donor (ECD)
organs and so forth. Kahan said that the system should work
for all living donors, no matter which DSA they are in.
Ascher
agreed that the amount of advantage is small in some areas.
It is not enough. Sometimes they will be waiting more than
2 years. The value of four points decreases every year as
the waitlist grows.
Most agreed
that it would be too complicated to award preference points
to family members of deceased donors. Families are complicated
entities, there is a possibility of coercion, plus there is
the difficulty of making this offer to a grieving family.
Most agreed, however, that if you are a living donor, there
should be some preference given that will allow a transplant
to occur within 2 years. Implementation would be up to OPTN.
It was
decided that SRTR should present their data to the plenary
session.
An Alternative
Preference System
Mark Nadel
discussed an idea to increase the supply of donated organs
by adopting "a policy of reciprocity, a kind of organ
insurance."13 Those
who committed to donate their organs in advance of their death
should be rewarded with a small preference in the event that
they need a transplant. This reciprocity model would serve
as an incentive for people to donate. Such proposals have
been the topic of a dozen or more medicolegal articles. The
1993 UNOS report gave it a mixed review, recommending future
discussions. Nevertheless, this idea was ignored in the 1993
Government Accounting Office (GAO) report on organ donation
and in the 1999 and 2003 House committee hearings on how to
increase donations. He said that this idea differs from Lederberg's
proposal or the Lifesharers' club-type preferences, which
give too little weight to medical considerations. It is more
akin to a local preference by which you receive preference
within your status group. You cannot go ahead of somebody
in a higher-status group. Where there are no status groups,
give points (2 or 3) where there is not a status system (MELD).
The marketing
campaign could be framed with an aversion to harm message,
which makes people more likely to act. Appeal to the most
disadvantaged by including a "John Q" provision.
Two benefits
are envisioned: Such a system would make it in the medical
self-interest of an individual to donate. Doctors would be
more inclined to leave forms in their waiting rooms. People
could sign up at the DMV. He noted that under the present
system, a potential donor's wishes are not always honored
by families. Here, you can say to the family, "Look,
he opted in, so now it is time for him to meet his promise.
He died before he could get the benefit offered by this program."
Nadel
listed several objections that might be raised and offered
some arguments in support of his proposal:
- There
are no empirical data that it would work. Nadel said this
is true, but we should test it.
- This
approach corrupts pure altruism. Nadel said that this approach
is reciprocal altruism. You can save many lives a year.
- Introduces
a non-medical factor in the donation process. Nadel said
that right now half of organs are wasted because they are
buried. This system is better than "local first."
Data show that people don't really focus on that. This approach
would increase donations because people would perceive that
they get something back.
- Some
religions might oppose this system. Nadel asserted that
religions that opposed donation are probably against transplantation.
- Uninformed
people who did not register would now face another obstacle
to transplantation. Nadel said that harm to the uninformed
is no greater than from "time on waiting list."
He further
proposed that each OPO dedicate some funds annually to underwrite
at least one transplant per year for someone who otherwise
could not afford a transplant.
Kahan
asked about how such a system would handle someone who is
already sick. Nadel replied that there would be a phase-in
so that those who have been members longer would have preference.
Burdick
mentioned a white paper that was written some years ago. Ethicists
have a problem with deeming one person worthier than another.
The view has been to see this scarce resource as a national
resource given solely on the basis of need.
Kahan
asked about what it would take to assemble this registry.
Nadel replied that donor registration databases already exist
in some states.
Ascher
asked about how a demonstration project could be conducted.
Nadel said that it could be tried in a state or an OPO. Test
willingness to donate in areas where the program is marketed.
Levine
asked what would happen if someone changed their mind. Nadel
said he hadn't really thought this through, but the decision
should be reversible albeit with some small fine or other
penalty. He said that the system would also have to address
the possibility of fraud.
Merion
said that in regard to the 26-odd states that have developed
donor registries: It is a registry of intent, not consent.
The registry includes many minors because it is promoted through
schools and so forth. Nadel said that parents could register
their children.
It was
suggested by the Subcommittee that Nadel present his proposal
during the public comment period.
Valuable
Consideration
There
was some discussion about the original language in Frist's
bill regarding paired exchanges.
Kahan
asked about which entity will determine what constitutes valuable
consideration. Agrawal responded that the question about the
scope of valuable consideration may be answered through a
lawsuit. The court then has the question before it, and the
court will interpret the law. The other way is that the Department
of Justice decides to prosecute some questionable behavior.
There are states that have "copycat" legislation
so it could come up in state courts. Typically, this type
of issue would be interpreted by a court. Kahan asked who
would guide ACOT about what constitutes valuable consideration.
Agrawal said that the statute does not give authority to the
Secretary to define valuable consideration. Levine suggested
that ACOT figure out an approach and try it instead of going
first to the Department of Justice.
Agrawal
said that the Secretary could be given regulatory authority
to define valuable consideration in this context. Another
way would be an advisory opinion process. Both of these models
have been used for Medicare-type issues. Levine noted that
a strong ACOT endorsement may stimulate Congressional action.
Agrwal
suggested bringing the issue to ACOT and then go back to the
Subcommittee to work further to develop a recommendation to
bring to the November meeting. Burdick observed that the time
would be short for taking action. We need to address specific,
practical details for demonstration projects, in particular.
He raised the potential problem of boundaries issues by asking
the group to consider the scenario of two deceased donors
in two different states. What would happen if and when family
members note the differences in valuable consideration?
Agrawal
asked if it would be possible to have a demonstration project
across state lines to test some sort of incentive. Burdick
said that usually demonstration projects compare one action
against another. Gunderson noted that we already have inconsistencies
from state to state about using DCD donors, definition of
brain death, and so forth.
Report
and Recommendations of the Valuable Consideration Subcommittee
(Subcommittee A)
Gail
Agrawal
Kress
reiterated that up until this time ACOT always has issued
consensus recommendations, but we may be diverging from that
tradition now. The votes we will take today signify direction
to the subcommittees as to what they should work on between
now and November. If we have a supermajority against a proposal,
we will not proceed on that item. If there is enough interest
on an item, however, we can invite a speaker on the topic
and flesh it out for November.
Valuable
Consideration
Kress
introduced Gail Agrawal, saying that the Valuable Consideration
Subcommittee is considering some alternatives to the purely
altruistic system that we now have. Agrawal presented a discussion
draft prepared by the Valuable Consideration subcommittee.
Her plan was to set the stage to facilitate a discussion to
see if we can systematically identify some questions that
we must address in order to move forward on valuable consideration.
The NOTA
prohibition on valuable consideration is a criminal statute.
The overarching question is whether and what change or clarification
we might recommend in respect to this notion of valuable consideration.
When lawyers
say "valuable consideration," it means something
specific. It does not simply mean money, as many lay persons
think. In the general common law it refers to "anything
having worth, whether monetary or intrinsic, which induces
or motivates an agreement or a contract. Under this definition,
any incentive designed to motivate an anatomic gift, not merely
those with direct monetary value, would constitute valuable
consideration." Valuable consideration is not just "dollars
and diamonds." NOTA uses the term "valuable consideration"
but does not define it. No court has issued a definition in
the context of NOTA. This section of the Act does list some
specific exclusions that allow payment for donor expenses
and so forth. UNOS counsel has opined that the valuable consideration
prohibition is meant to prohibit monetary consideration (dollars
and dimes). This opinion is not binding on anyone, however,
and certainly not on the judiciary.
There
is a disconnect between the common law definition and how
we in the transplant community think about valuable consideration.
There are some consequences resulting from this lack of clarity:
- Uncertainty
about legal consequences could deter transplant centers
and OPOs from engaging in beneficial practices aimed at
increasing organ donation
- Uncertainty
about federal preemption of state law could deter state
legislative action to create incentives intended to increase
organ donation
- Risk
of criminal prosecution for innovative programs that provide
incentives to increase donation
- Federal
preemption of state laws that create incentives to enhance
donation on the grounds that the state law conflicts with
the federal prohibition
- Loss
of potential donors.
In its
breakout session, this subcommittee talked about giving preference
points to families who had consented to donation. Would that
be valuable consideration? We don't know the answer.
Agrawal
posed several questions to the assembled group:
Should
ACOT recommend to the Secretary that he seek to have the meaning
of "valuable consideration" and the scope of the
prohibition clarified? The participants concurred that this
question should be pursued for both living and deceased donors.
Should we continue work on the question? Williams specified
that the deceased donor category should included donors deceased
after cardiac death (DCD).
If
ACOT concludes that the term "valuable consideration"
should be clarified, how should the clarification occur? Agrawal
offered several options for the group to consider:
- Amend
NOTA to include a definition of valuable consideration.
If a definition were included, how should it differ from
the common law definition?
- Amend
NOTA to specify additional exclusions from the prohibition
on valuable consideration. If exclusions are added, what
incentives or practices should be excluded?
- Amend
NOTA to authorize the Secretary to promulgate regulations,
subject to the notice and comment period prescribed by federal
law, to define the term and/or describe practices or incentives
that will not be deemed to constitute valuable consideration
for the purposes of NOTA. If the Secretary were to seek
such authority, should its exercise be subject to specified
limitations or guidelines?
Harmon
suggested that we should just make the recommendation without
going into detail about how the change should be made. The
reality is that the statute is where to address it. Agrawal
said that there are other ways that may be easier. Also, if
a center wants to try some incentive program, we could seek
an advisory opinion from the Department of Justice. Our choice
of approach does have some consequences.
Going
through the legislative process will be laborious and slow.
We have a supportive Secretary. We should act now. Kress said
that whatever we do in this area will entail a legislative
process. If we list in the legislation exactly whatever is
permissible, then anytime we want to make a change it is already
graven in stone. The second approach is more flexible, but
a different Secretary could take a different approach.
Kahan
asked why the language permitting demonstration projects was
stricken from Frist's bill. Delmonico said that Frist had
to deal with clear opposition to living donors receiving money.
Demonstration projects might have been seen as a slippery
slope that would lead to payments to living donors. The demonstration
projects were not defined. Congress was not willing to discharge
that responsibility to whomever might be Secretary at the
time. If the nature of the demonstration projects had been
defined, the language might have been left in. Kress said
that he has heard various speculations, but we cannot really
know Congressional intent, especially on a negative, i.e.,
on why a provision was left out, since any statute involves
so much compromise.
Delmonico
said that the lack of a definition leaves paired exchanges
in limbo. Congress knew that paired exchanges were already
underway. They chose by their silence to affirm the 1984 NOTA.
Agrawal said that seems a stretch because the sentence about
familial, emotional bonds, and so forth was also struck.
Agrawal
asked if everyone agreed that the term "valuable consideration"
should be restricted to meaning money or a monetary equivalent
given in the context of organ procurement, donation, and so
forth? Delmonico used the term monetary enrichment.
Michael
Williams said that NOTA was written 20 years ago, and we need
to shine a light on it. The world of transplantation has changed.
We want to avoid the situation that someone is induced to
take a risk that they would not normally take or that someone
who is disadvantaged would be induced to do so. Agrawal said
that such language adds another level that reflects the strength
of the inducement. Harmon asserted that it is abhorrent to
buy or sell organs. Paired exchanges are not enriching anyone.
Ascher suggested that we should consider valuable
consideration to be monetary enrichment. We already have safeguards
in place to make sure that people don't take unacceptable
risks.
Levine
stated that living donor expenses are not prohibited. They
are expressly excluded from the prohibition against valuable
consideration. Agrawal said that the question of who is going
to pay is still open even if payments are legal.
Kress
said that it is common practice in law school to use hypothetical
examples as a learning device to test our concepts, and he
proposed one such hypothetical example. We have heard about
situations with living donors where it is suspected that a
gift or something has been given to induce them to donate.
If it is discovered that a family has given something of value
to someone in the family as an inducement, should that, hypothetically,
be regarded as a criminal violation? Agrawal said that it
is a criminal violation. There is no reporting obligation,
though. Kahan said that often, when he deals with families,
he will see that the donor has a new car or is going to college
3 or 6 months later. It happens. It is just part of the interaction.
No program is clean of that. Ascher cautioned that if the
transplant team knows about it ahead of time, the donation
should not occur. It is a duty to see if there is hesitation
or uneasiness on the part of the donor. Williams said that
the difference is whether it is given or promised ahead of
time as an inducement or if it is given afterward as an expression
of appreciation.
Turrisi
asked if there is a way for CMS to issue an opinion or something
to say that lost wages, out of pocket living expenses, and
so forth are reimbursable expenses. Once that happens, insurance
companies usually follow suit. It is analogous to organ procurement
expenses. That is the crux of the matter. There is a disincentive
for people to become living donors. Roger Evans noted that
there is a process by which CMS makes decisions about reimbursements.
We should recommend that CMS make a coverage decision regarding
expenses for living donors.
Solarz
posed another hypothetical: Under this framework, would a
flat fee paid to all living donors be legal as compared to
reimbursing actual expenses? If you pay the same flat fee
to all living donors, are you in fact paying for the organ
for those who have lower actual expenses? That is problematic.
It seems murkier in a legal framework.
Diana
Lugo-Zenner observed that states could do something similar
to what Wisconsin did ($10,000 tax credit/deduction). Turrisi
said that she does not believe that CMS will give us a reading
because we lack a definition for valuable consideration. Turrisi
said that we need to hear from CMS that it will reimburse
the costs associated with living donors.
Agrawal
returned to the question of demonstration projects. Ascher
said it is important to work under the Secretary's
guidance to embark on a series of demonstration projects.
We must clearly define the parameters of any demonstration
projects. She does not envision any arm of a demonstration
project to include monetary enrichment. Agrawal
asked about what kind of limits we would want to set. The
participants suggested:
- No
monetary enrichment.
- An
ethical analysis of any proposed demonstration projects.
One component must address the inducement/appreciation aspects.
- Research
component to look at the same people who are contributing
to the research project having access to transplantation.
For example, if, as a result of a demonstration project,
suddenly many more minorities donate, we need to ensure
that those people would get access to transplant.
Agrawal
then went through the tabular summary of valuable consideration
options (prepared by Roger Evans and attached as Appendix
A). The purpose of the voting on these actions was solely
to give direction to the Subcommittee as to which items it
should pursue further, and flesh out in further detail at
the November meeting, and was not to be regarded as a vote
for or against the outlined proposal itself.
Appendix
A. Tabular Summary of Valuable Consideration Options
Most,
if not all, agreed that the first six options were acceptable.
The results of further voting are recorded below.
- Item
7: Funeral expenses are certainly an inducement to financially
disadvantaged families. Agrawal said that paying for funeral
expenses would likely constitute monetary enrichment because
it is a foregone expense that the family would have to pay.
Reimbursement of funeral expenses would be an ideal demonstration
project. Kahan noted that this option was on the books in
Pennsylvania but was never initiated because a concern about
its legality under NOTA. The vote indicated that this item
should remain under consideration by the Subcommittee.
- Item
8: Tax deduction/credit. Solarz said that this option is
financial enrichment. Kahan said he would not support this
option. Four voted to keep this under consideration restated
as a state tax advantage of some sort. Eight voted against.
- Item
9 (refundable credit): This item was not well understood
and was not discussed at any length. Five people voted to
keep this on the Subcommittee's agenda, and eight (or more)
voted against.
- Item
10 (life insurance policy to be received by a person or
organization designated by the donor following successful
deceased donation): Nine people voted to keep this on the
agenda; four voted against.
- Item
11 (guaranteed lifetime health insurance for living donors):
Solarz mentioned having some mandatory, minimal insurance
criteria that would say that companies must insure for this.
Carlton Young suggested that such a program might help keep
living donors in follow up for the registry. The National
Marrow Donor program may already be providing life insurance,
so there is some precedent. Nine voted to keep this on the
agenda; four voted against.
- Item
12 (bonuses paid to individuals and organizations involved
in organ procurement): Kahan said that we cannot just dismiss
bonuses; they have been part of the reason for Spain's success.
There was some discussion about whether some OPOs are already
paying bonuses to their coordinators. Bob Merion said that
his OPO checked to see if other OPOs were compensating or
giving bonuses. It appears that some were giving bonuses
for exceeding a certain number of donors per year and so
forth. Sollinger said that such bonuses could totally destroy
public perception and send us back to the ice age. They
are improper and would also be a disaster from a public
relations standpoint. Sollinger said, however, that we definitely
need to discuss this topic, especially if it is already
happening. We need to learn something about this. Seven
voted to keep this before the Subcommittee; seven voted
against.
- Item
13 (living donor/deceased donor exchanges): Most agreed
that this is already happening. Giving a live donation to
help a loved one move up the cadaveric list is a real motivator.
There is no financial enrichment. Fourteen voted to keep
this on the agenda; zero voted against.
- Item
14 (direct cash payment): not acceptable to the group. Four
voted to keep this on the agenda; ten voted against.
Son-Ja
Jones spoke about how frustrated she feels that the group
is just now trying to figure out how to use incentives to
get more organs. Just now you are starting to share about
what works and what doesn't. Most of the proposals just help
compensate for what the donor goes through and the risk they
are taking.
Agrawal
said that perhaps the group should talk about proposals that
would be implemented if there is some adverse consequence
to the living donor.
Bob Merion
addressed the impact of previous living donation on waiting
time for a subsequent deceased kidney donor transplant. He
presented SRTR's data on the topic. A very recent change places
prior donors "at top priority," following zero-HLA
mismatched organs. The benefit of the extra points is not
the same in all parts of the country. In a low-wait-time DSA,
the value of 4 points is significant. There is far less real
benefit to those in high-wait-time DSAs.
Kahan
opined that this is not enough of a reward for this group
of patients. Might we just give them more points so they move
way up? Merion said that it would be possible to just increase
the number of points so that living donors would be way above
the median time for every OPO, say, 100 points. Eight or ten
points would not be enough in a couple of years to give living
donors much of an advantage because of the increasing length
of the waitlist. Nevertheless, if we just award points, they
would still be preempted by zero mismatch and pediatric time-expired
candidates.
Presumed
Consent
Phil Berry
presented some information on the presumed consent question.
He referred to an article entitled, "Do Defaults Save
Lives?"14 He said
that the general population will take the path of least resistance.
This study gives a glimmer of hope for considering an opt-out
system. The Valuable Consideration Subcommittee discussed
the pros and cons of presumed consent. Until we consider this
option, we do not know what will work. We are losing the battle.
It behooves us to consider every option.
This Subcommittee
would like to see ACOT validate the consideration of presumed
consent as one other option to boost donation. We would like
to develop a template for a demonstration study. We know that
a Gallup poll will be coming out in the next 4–6 months
so we can look at what the American public thinks about presumed
consent. Four questions on the survey deal with presumed consent.
After this survey, we will have some data on which to base
our actions on this topic. Where do we proceed after today?
He posed
a series of questions to the group. Again, the purpose of
the voting on these actions was solely to give direction to
the Subcommittee as to which items it should pursue further,
and flesh out in further detail at the November meeting, and
was not to be regarded as a vote for or against the outlined
proposal itself:
- Should
ACOT recommend to the Secretary that an opt-out system based
on a model of presumed consent be explored as a method to
increase the number of organs procured from deceased donors?
Thirteen voted for taking this action; one voted against.
Solarz cautioned that an opt-out system will never get off
the ground. Be careful about making statements about supply
and demand because it is different for each organ. Bob Higgins
suggested that we need to do better in terms of organ utilization.
Kahan said that we could face public opposition. If the
survey results indicate that this is not going to be accepted,
then we should abandon it. Sollinger said that presumed
consent could be an important trigger to get more organ
donation. What would be needed to start a demonstration
project? Kress said that it would take legislation to change
it. Levine said that consent laws are handled by the states,
so a state could change its law. Ganikos predicted that
the results of the poll should be available in mid- to late
October. Delmonico said that the American Civil Liberties
Union in his area imposed upon the state legislature not
to move forward. We will need something to overcome that
opposition. Ascher said that in 1984 the majority of people
supported organ donation in a Gallup poll, but conversion
rates were 30%. There is a disconnect. We need to see what
works through demonstration projects. Harmon said that in
this country, the individual is more important than the
state. We should do the demonstration projects and then
decide which way to go. The demonstration project would
show us if people act as they say they will.
- If
ACOT concludes that a model of presumed consent should be
explored, what form should that exploration take? Most supported
the notion of demonstration projects (13 for, 1 abstention).
It may be premature to move toward federal legislative initiatives
to encourage state action. If a state approach were implemented,
there would have to be a state registry. There would have
to be a public awareness program. It would be tailored to
the state. Young asked if we might end up with a patchwork
quilt? The answer is yes, each state could have a different
approach.
- If
ACOT concludes that presumed consent should be explored,
should ACOT recommend a specific presumed consent model?
The majority (6 for, 2 against) thought that the Subcommittee
should deal with both pure and modified presumed consent.
- If
presumed consent were explored, a method of opt-out would
be required. Should ACOT advise the Secretary about the
characteristics of an opt-out system? Twelve voted in favor
of advising the Secretary on this topic.
ACOT
Fair Treatment Subcommittee (B)
Breakout Session
Members:
William
Harmon, chair
Nancy Ascher
Robert Gibbons
Amadeo Marcos
Son-Ja Robet Jones
Flora Solarz
Kathy Turrisi
Mike Williams
Carlton Young
Hui Hsing Wong
Hans Sollinger
Other
participants: Deborah Shelton (a reporter from the St. Louis
Post Dispatch), Alan Leichtman (SRTR), and others.
William
Harmon welcomed the group and described the process. The Fair
Treatment Subcommittee will be expected to define the scope
of the problem and generate recommendations. The group will
also hold two conference calls later on: The first will be
used to make progress reports and the second to make actual
recommendations. Harmon expects each of the seven subgroups
to have its recommendations ready to present for the second
call. Clearly, most of the work of the committee will be conducted
after this meeting and will be summed up during the conference
calls.
There
are seven specific areas to be discussed, and the Subcommittee
will generate recommendations around each of these areas (see
below). Each subcommittee member is on at least two of the
seven committees. The process for the breakout session will
be to have one set of committees meet to talk among themselves,
define areas of interest, and then report back on future activities
and responsibilities. Then, the second set of committees will
meet and go through the same process. Dr. Harmon noted also
that the SRTR is present and encouraged the members to think
about specific questions to ask.
First
Set of Subgroups:
Nondirected
Donors — Harmon, Young
Harmon
described the issues discussed in this subgroup.
Two
types of donors — First, there is the pure,
directed, straightforward person who comes and wants to give
an organ. Second, there are swaps in which there is a living
donor and a deceased donor swap. In this situation, there
is a net increase of one on the list. Our sense is that it's
the responsibility of the hospital where the donation will
occur to do the donor work-up. If the hospital where you're
doing the transplant has different criteria, it's up to them,
not the facility where the work-up started. In other words,
you don't have to do a new work-up, but you can. You can't
force a donor on a hospital.
- Recommendation:
have the hospital where the transplant occurs do the donor
work-up.
- Recommendation:
Do not force donors on a hospital.
Choice
of hospital — The choice of hospital should
be up to the donor. If the donor goes to Mass General and
they say the donation is fine, it's not okay to tell the donor
they have to go somewhere else. Unless it's a living donor
swap, you can't tell the donor that they have to go somewhere
else.
Williams
— This doesn't work for those who are underprivileged,
though.
Harmon
— We're talking about the donor.
Williams
— If there is only one place to donate locally, but
they know it would be better to go to Illinois, what if they
can't get there?
Harmon
— It's just that we have to say that the donor gets
to choose. They get to decide — this will get into allocation
later. As a principle, you should not push a donor anywhere
except when it's a living donor swap.
- Recommendation:
Donor should be allowed to choose the hospital where the
donation will occur.
Allocation:
If someone comes in to donate, should that organ be allocated
in the hospital, the state, the region, or the United States
as a whole? How do you allocate?
Solarz
— There's a medical reason for having the organs be
given to the local people. It's true for liver, it's probably
true for kidneys too.
Harmon
— In Region 1, the allocation is by hospital, not region.
It's like that also in Minnesota. In DC, however, they allocate
within four hospitals: they are doing it by consortium. Our
view is that it should be allocated by the donor hospital,
not on a wider basis, unless the local group feels they can
share without losing quality. Our scheme is hospital first,
not OPO first, as UNOS is.
- Recommendation:
Allocate organs with in the local donor hospital first,
unless the local community has selected another system (e.g.,
consortium-based).
- Recommendation:
Select recipient based on UNOS run of the local hospital's
lists (except for children).
Solarz
— Would they be able to pick any patients?
Harmon
— Then, we recommend that it's done by UNOS run in that
hospital, down to 5 patients. Practically speaking, people
take the best recipient rather than going down the list. We're
saying, use the regular list — but not for children,
though.
Turrisi
— We always direct to child first, then go down the
list after that.
Harmon
— That's okay, that's how you structure your list. This
is for kidneys. You use your regular UNOS allocation and that
may involve always having a child at the top of the list.
For nondirected donors, we had said you can't choose a class
or category — for example, "only" donate to
firemen, African Americans, Yankee fans. You can say donate
to a PERSON, but not a class. We had a discussion at the last
meeting about children. We decided to say no, you can't say
the donation should go to children specifically, and I was
the one leading that debate. I said it because it was a slippery
slope and they should go to a pediatric hospital if they wanted
to go to a child. But, it turns out there aren't very many
pediatric hospitals that are appropriate. We are looking at
the data now. So, do we want to allow them to say directed
to children as a class? It would be the one exception.
- Recommendation:
Reexamine the issue of prioritizing children as a class
of recipients; create recommendation for prioritizing children.
Wong —
Allocation allows kids to move to top of list anyway, so it's
not that different. They get offered marginal organs and it
clogs up the system, so this system would help with that problem.
Sollinger
— There is universal sentiment all over the world: people
will do for kids what they won't do for adults.
Harmon
— We'll work on the pediatrics issue and develop a rationale
for kids being a special group.
Solarz
— If you have a 60-year-old donor you don't have to
offer it, and they don't have to accept it.
Leichtman
— In terms of choosing the recipient, the issue is to
follow objective criteria — like a matched run —
in which you have an order of patients, and then the patient
from that list could come from donor preference. As long as
you offer the donation in the order of the matched run, it's
okay. We had a woman who requested that we find a sensitized
patient and we did that.
Harmon
— That's a slippery slope.
Williams
— We need to describe the choice to give to a child
as legitimate discrimination, while other forms of choice
are not legitimate. What if they say, don't give it to a child.
Then what? We have to look at the alternative.
Evaluation
— no changes.
Follow
up — no changes
Quality
of Life — Williams, Turrisi, Jones, Solarz
Williams
— This is in the context of the Burden of Disease presentation,
and with the note that none of us is a statistician or a quality
of life (QOL) person. But, two of us have received transplants.
Our group went to fundamental questions. We're looking for
the basics.
So, the
first question is should we use QOL to look at outcomes in
transplantation? The answer is yes.
- Recommendation:
Use QOL to examine outcomes in transplantation.
The next
question is, what do we measure for QOL? In terms of measurements,
Flora has identified six things, and there are many more ideas
of what to look at. The debate has been about biological markers
(patient and graft survival), but QOL is psychosocial, economic,
about the family, the caregiver burden, etc.
- Recommendation:
Incorporate nonbiological markers in assessing QOL (e.g.,
psychosocial, economic, family, caregiver).
The next
question is: What tools do we use to measure? Not much has
occurred in this realm to date, but maybe we don't know the
literature. Then, what is the validity of the tools? Do they
have face validity?
- Recommendation:
Explore validity of tools used to measure QOL.
- Recommendation:
Develop transplant-specific QOL measures.
Finally,
we have to ask for what purpose do we collect the data? Is
it for the individual, for the physician, transplant center,
OPO, OPTN? It ranges from the individual to an organizational
approach. There are many purposes for gathering data —
for policy, prognosis, prediction, persuasion (e.g., using
QOL data to persuade people through informed consent to either
have or not have transplant).
This group
has to ask HHS to begin to incorporate QOL into organ transplantation
issues. We've had calls for research on this — using
existing data sets on SF-36, data on the QOL arena in medicine
(especially in terms of diseases that may result from transplantation).
- Recommendation:
Ask HHS to incorporate QOL into organ transplant issues.
Are these
tools valid for transplant patients? Then we can develop transplant-specific
tools.
Lastly,
we can learn from MELD/PELD: If we will use the data to drive
policy, then we should have a model about who is affected
(e.g., patients, OPOs) and evaluate the predictions.
- Recommendation:
Generate a model that explores who is affected by QOL issues.
Turrisi
— Some people have tools (e.g., Vanderbilt). I know
Larry wants to do studies with particular tools. My issue
is that I don't feel the data are reflective of QOL issues.
I don't think that we are looking at all of the tools and
what should be asked.
Solarz
— There are many questions. Do your transplant outcomes
match your expectations? If not, have you been able to adjust?
What are the measures of regret and satisfaction? What are
the measures of interactions with the provider? What is the
financial burden, the family dynamics? We don't ask these
things on the SF-36, but they are important. It's beyond "do
you feel well and can you function", it's "are you
satisfied with your life?" There is something missing
in the scale.
Wong —
That's not what's intended in the study. Some of these are
center-specific things to put in the model. You have to be
careful about asking validated questions. These are legitimate
questions, but this is a research model for predicting burden
of disease.
Turrisi
— QOL is more than burden of disease. It includes factors
that affect people in the long-term. We may think they're
doing great, but they think they're doing horrible, for example.
Solarz
— A lot of the elements are out there, but they have
not been brought together.
Wong —
You can bring it into the model, it can take a lot of data
from different sources. Studies that have done this well exist,
and they can be added in. You are assuming that the SF-36
is the only measure being used, but it's only one among many.
They are asking other questions.
Turrisi
— Larry Hunsicker didn't show us that, though.
Harmon
— So, should allocation be based on outcome? This is
the real question. Should we allocate to those who are going
to do best, for example, to a 20 year old vs. a 70 year old?
Is it time for the OPTN to look at outcomes and develop an
allocation based on outcome?
Young
— The problem is that we don't know enough about the
factors that go into it. African Americans (especially men)
wouldn't get any transplants if we just look at outcome measures.
Small, Asian women do the best because of size, genetic differences,
etc. They have less trouble with rejection, better survival
rates. You would exclude a big population of people who would
otherwise get treatment if you just look at outcomes. It gets
into rationing.
Williams
— There is a lag between the evidence and where we want
to be. If you want to use objective, valid measures to predict
who will do best — then you have to incorporate ways
to improve those measures for people who don't currently have
good measures, so they can get there.
Sollinger
— I am 100% with Young; making criteria to exclude groups
is a problem.
Turrisi
— In terms of outcomes when you look at graft survival
if you just look at it, yes. But you have to look at other
things for QOL.
Harmon
— We have to have a reasonable basis for making a recommendation.
Minimal
Listing — Marcos, Gibbons, Sollinger, Wong
Gibbons
presented the group's report. There are two proposals by UNOS:
one is for minimal listing criteria in which a person with
a MELD score of less than 10 is not placed on the list. If
you went on the list with a higher number and get reduced,
you can stay on the list; also, if you were on the list with
a lower score before the new rules went into effect, then
you can stay on the list even with a lower score. Gibbons
described one disadvantage of this approach as that there
is an entire group who is out of the system: They start as
a 9, later they become a 15, but they don't get followed up
with and never make it onto the list.
Marcos
— If someone comes in and doesn't meet the criteria,
when can they be reassessed?
Harmon
— It's unclear; they are not part of the system, and
the routine system does not apply.
Gibbons
— If MELD criteria are used, and someone gets a score
below the minimum — would the provider hold onto them
until they raise the score above 10?
Harmon
— Some will, but there's no requirement to follow the
patients.
Gibbons
— In terms of the cons, now we have a new category that
reminds us of the old status-level categories. There will
be lots of petitions for exceptions: someone who has a MELD
of 7, but has cancer, and so on. There will be lots of exceptions
that will have to go to the review boards. Some of the regional
review boards are good and some aren't.
Wong —
The way it is now, if you are below 10 and want to go on the
list, you have to go before the boards. Many people don't
know their boards.
Gibbons
— There are a lot of OPOs that are transplanting these
patients; one-third of patients in many places have a score
of less than 10. Some are instances of bad organs going into
good people, where others have refused the organ before. Some
are patients with exceptions.
Harmon
— At a minimal offering, we are looking at a modified
version of regional sharing.
- Recommendation:
Explore adopting a modified version of regional sharing.
Wong —
The way the system works, you offer the organ locally up to
score of 15; if there is no local patient, you go regionally
to patients up to a score of 15. If there is no patient regionally,
you return to locally for lower-scoring people. What it means
is that very few offers are made to patients with lower scores,
unless it's an instance of a strange blood type or bad organ.
Gibbons
— There are several issues. Broader sharing means there
is no need for minimal listing criteria. It provides an allocation
system based on a broader population, so there is a greater
likelihood for getting organs. This gets around the need for
minimal listing. But, it ends up being bad because the patient
is lost to follow-up.
- Recommendation:
Explore ways to retain patients for follow-up.
There
is a caveat — the proposal for sharing is nested in
identical blood types, which is strange. It should be for
compatible blood types. If I have an O with a 14 and there's
a patient with a MELD of 40 and a compatible blood type, the
organ should go to them.
- Recommendation:
Adopt a regional sharing process that is based on compatible
blood types rather than identical blood types.
Wong —
That's the current system, for liver it goes to blood type
first.
Harmon
— But O is universal, so O recipients are at a disadvantage
and have to wait longer when the organs go to other patients.
Wong —
If you don't have an O patient, but you have an A or B patient,
you would go regionally for the O, rather than locally to
the A or B.
Harmon
— Is the O recipient disadvantaged in that circumstances?
Where you use up the O livers on As and Bs. Can you do this?
Wong —
We looked at it for observed waiting times.
SRTR —
We could model a rule where an O is distributed to compatible
blood types. We need to know how many people get transplanted
and the impact on life.
Wong —
The liver committee looked at O organs going to A and B blood
types. It used to be done by adding a score of 20, but people
got complaints and so they modeled the impact. We showed no
impact on life if you use 20 or 30 extra points.
Harmon
— Let's not copy UNOS's work; let's think outside the
box.
- Recommendation:
Study the impact of a regional sharing by compatible blood
type model on O donors.
Sollinger
— The liver is different because it's a loss of the
graft and you can't salvage it unless you bring the next compatible
person in. There's a huge time pressure. They have an hour
to decide and by the time they decide, it's too late. We need
to share more. I'm all for the MELD cutoff, but we need rules
that do not lead to greater graft loss. If sharing leads to
greater graft loss, it's a losing proposition.
Gibbons
— An expanded list of donors should not be part of the
program. Special cases should be at the discretion of the
local OPO — they are the ones that aren't on first offer,
they are the ones losing time.
Wong —
There's no definition for expanded donor for livers. With
kidneys, it's more clear.
Sollinger
— What about "non-heart beating organs?"
Wong —
Those are rare.
Harmon
— No, it's 20% and growing. We have to talk about the
future.
Gibbons
— We started by looking at UNOS proposals: minimal and
sharing. Our primary interest is that if they use these, then
they don't require minimal listing if they have broader allocation.
We need a careful study of the question of whether broader
allocation follows blood type rules.
Solarz
— It depends on your OPO. In New York, almost all of
them are classified as extended criteria donor organs, we
think. We have a long waiting list.
Gibbons
— If they are all ECD, then that destroys the issue.
We need a clear definition for ECD for liver as for others.
We have a definition for extended donor.
Wong —
UNOS is, for the first time, considering a form of broader
allocation. We are looking at comments. Minimal listing stuff
is getting creamed. We can make a statement one way or the
other and we should do so. Minimal sharing gets you around
the problems of minimal listing.
- Recommendation:
Provide comments on UNOS consideration of minimal listing
and broader allocation issues.
Sollinger
— We need a better prediction of survivor. A list, not
just MELD, needs to be created. We asked for that in the first
meeting from the SRTR, so we could define the criteria. You
need to model it and they're working on it.
- Recommendation:
Create a list that helps predict survival (beyond MELD).
Special
Needs of Pediatric Patients — Harmon, Wo
Harmon
presented the group's report. In terms of background, there
is a social history of providing preferences for children
(e.g., education, not being forced to work). Children have
always been looked upon differently, and so it's reasonable
to have special cases for them. We will summarize OPTN methods
for preferences for children for these things. We will write
a background paper on kidney, liver, heart, and lung.
- Recommendation:
Write a paper describing children's issues that addresses
kidney, liver, heart, and lung and describes how children
have been viewed separately as a class, OPTN methods for
giving preference to children.
Allocation
— We need a principle that children are special and
that providing preference to them does not set a precedent
for other groups. If we use the facts of children's special
treatment in other instances, then this will set a substantial
principle. Then, saying that a non-directed donor can contribute
to a child because they are special group is all right. Most
people will agree with this.
- Recommendation:
Create a principle that children are a special class and
may be provided preference without setting a precedent for
other groups.
Children
as donors (DD and LD) — We want a section on this. We
need to note in the paper that there are a large number of
children who have been deceased donors. In fact, they are
more likely to be donors than recipients; and they are very
ideal donors. We also want to discuss living donors. It's
not controversial: children shouldn't be living donors. There
are a few instances where it's reasonable (e.g. a 17-year-old
mother who donates to her own infant). But, they should not
be used for living donors for adults.
- Recommendation:
Include, in the paper, an overview of children as living
and deceased donors. Include federal regulations and other
rules that apply to children.
Wong —
Legally they are not emancipated, they can make medical decisions
but they are not emancipated. Medical decisions are different.
They can't sign contracts and engage in other decisions. It
doesn't mean they have to pay their hospital bills. Laws on
adulthood are different. The principle is that we don't think
is appropriate unless there are special circumstances. With
liver, it's a harder ethical decision.
Solarz
— There are risks associated with liver donation and
a value to the mother not putting herself at risk —
in terms of her being there to rear her children, for example.
Wong —
That's very legitimate. An ethics committee should review
this when it's done.
- Recommendation:
Have an ethics committee review the paper upon completion.
- Recommendation:
Track and note how frequently child donations occur to explore
the need for exceptions in regulations or a process for
appealing to ethics committees.
Williams
— We should track how often exceptions occur. We can
define the need and see if we need exceptions in regulations
or a process for appealing to the ethics committee.
Harmon
— There was a recent study published on 40 or 50 teens.
There were a fair number of kids donating to older adults,
like a 13-year-old donating to a 54-year-old. We might need
to have a principle that kids only donate to kids.
Clinical
trials. There are rules on children from the feds. We should
restate the rule and the principle. Reemphasize the issues
and clarify them.
Transition
to adulthood — After transplant, children transition
to adulthood and this has not been looked at carefully. How
much insurance do they have? Do they get their drugs? Plus,
young adults don't have an advocacy community, and they are
not getting kidney transplants.
- Recommendation:
Explore issues of transition to adulthood for child organ
recipients.
ECD Status
Evaluation — Solarz, Turrisi, Marcos
Solarz
— In terms of looking at ECD, the kidney is clear. We're
looking at livers here. Approximately 80% of ECD livers are
from non-heart-beating donors and cases where the only organ
taken is the liver. The idea is to look at those and evaluate
donors for primary nonfunction, to see if there is a threshold
of what an ECD would look like. We want the SRTR to look at
ECD livers. We didn't talk about hearts and ECD living donors.
- Recommendation:
Examine threshold for ECD by exploring ECD liver donations
to explore donors' primary nonfunction.
In terms
of hearts, there are centers that might take more marginal
donors if they were offered up. How do they get to say, yes,
I want that heart? The question was about the donors who are
aggressive and want to be donors, but they are pushing it.
Sollinger
— They still call UNOS, and the center would say they
want the heart.
Harmon
— They have their circles that define when it's reasonable.
They call within those geographic circles.
Turrisi
— Are there centers that are interested in marginal
donors and can't get them?
Harmon
— "Marginal" is more a case of a 56-year-old
heart versus a 55-year-old heart, that sort of thing. Waiting
time has been decreasing; we're seeing success in the heart
area. We need to retrieve more organs per donor. Another issue
is that there are a number of potential heart donors who are
referred early and may, due to management at end of life,
have cardiac malfunction. It's a single time-point offer.
Having crossed over and become brain dead, they might be able
to be managed and resuscitated and could be able to be rehabilitated
to be acceptable as a heart donor.
- Recommendation:
Explore issue of brain dead donors who may be able to be
resuscitated and rehabilitated as a heart donor.
SRTR —
In terms of organs per donor: it puts the community in a schizophrenic
position with competing goals. Is it to increase organs per
donor? You wouldn't then go after ECD with two kidneys, or
just a liver donor. It's a disincentive. I am troubled by
goals that conflict. Having lower organs per donor would be
ok if you had the same donors as last year, plus 14 extra
livers.
Sollinger
— There are huge costs for ECD donors. It has a long-term
negative effect on organ donation.
Organ
Refusals — Turrisi, Williams
Turrisi
— Barry thought that there were problems in the payback
system for kidneys because Maryland didn't get penalized.
Others felt it was not true, the system was getting ready
to change again and there may not be a problem. The system
is intact.
The whole
issue of organ refusals is connected to ECD and DCD organs.
We have a system where we have marginal organs and it takes
a long time to try to place them. A second issue is that we
want a better system of marking organ refusals and why they
occur. The UNOS change has refined the refusals better.
- Recommendation:
Examine why organs are refused and when these situations
occur.
The question
is, what should we do on DCD and ECD organs and getting them
through the system faster? Our recommendation is that the
DCD and ECD should come off the shared list.
The recommendation
is that there should be no obligation to share these, although
you can do it if you want to. You have to get them in quickly,
that's the key. There should be no mandatory offering.
- Recommendation:
There should be no mandatory offering for liver and kidney
DCD and ECD — they should come off the shared list.
Young
— You mean, for all ECD?
Sollinger
— No, for liver and kidney. The heart is not an issue;
they don't do it. If they don't accept it, they don't retrieve
the heart. It's said beforehand and, if nobody wants it, they
don't even take it.
Turrisi
— The issue is really about not having mandatory sharing
of the organs.
Young
— Can we ask the SRTR to stratify ECD kidneys in terms
of risk factors to see how often they are shared?
- Recommendation:
Ask the SRTR to stratify ECD kidneys in terms of risk factors
to see how often they are shared.
Turrisi
— People spend a lot of time trying to place organs.
One of the issues is that there is no need to mandatory share
in this sense, and then what do you do after that? How do
you get to the system where you're still not calling? Centers
don't want to be out of the loop — they might want it
one day. It's an issue of timeliness.
Turrisi
— There is another recommendation that the risk adjustment
needs to be included in costs.
- Recommendation:
Include risk adjustment in costs.
Unfairly
Treated Groups — Young, Gibbons, Marcos, Jones
Young
presented for this group. There are multiple issues:
Minority
status — We want more updates on the impact
the allocation scheme has had for minorities, and to analyze
all minorities (in addition to African Americans) to see the
impact. We will ask the SRTR to do this. The MAC committee
is asking to look at heart and liver access to the waiting
list. Data are hard to get, outside of kidneys. Liver and
heart are harder to get and it takes more work. The MAC committee
will give us the data to look at heart and liver.
- Recommendation:
Ask the SRTR to provide updates on the impact the allocation
scheme has had on minorities.
- Recommendation:
Get data on liver and heart from the MAC Committee.
Women
— There are access issues here too. Are women as a group
experiencing decreased access to transplants — either
getting on the list or when they are on the list? If that's
the case, is it based on socioeconomic status, ethnicity?
Where is the problem nested?
Harmon
— What about women as living donors? This was raised
as an issue in Amsterdam. Women are 60% or 70% of the donors.
Women are preferred donors, and men are perceived recipients.
We have the data, the issue is whether this is an interesting
question?
- Recommendation:
Explore issues of sex and access both in terms of getting
on the list and getting organs once on the list.
Insurance
— SRTR presented a study based on exploring insurance
as a predictor and looking at whether, if you were on the
list, you were getting an organ. African Americans are less
likely to get a transplant based on their insurance status,
even when they had Medicare. We want the SRTR to go back and
rerun the data based on the new allocation system to see if
the discrepancy still persists, and if so, why? If they have
the same socioeconomic status, why is there a difference?
- Recommendation:
Ask the SRTR to rerun data for the new allocation system
to see whether discrepancies exist regardless of insurance
status.
Wong —
In terms of the OPO, the difference is not as large. But,
access to the waiting list is the key issue. It's the first
and biggest barrier. That's where you are going to find the
most significant difference.
Turrisi
— We don't have the numbers for that. African Americans
are not referred in my state. When you get them referred they
get on the list, but we're trying to get them referred in
the first place. Medicare only patients who have to pay a
co-pay and fundraise to get on the list. There are a lot of
kidney patients who are Medicare only. There will be a bias
against them, because the centers have to pick up the cost
of the drugs.
Young
— They did show that African Americans had less access
to the waiting list and they had less access to transplantation
when they were on the list.
Wong —
SRTR found that the Medicare patients with private insurance
are less likely to be referred. There is a difference between
those who go onto the list, and then access off the list.
Williams
— How will discount cards affect this? Immunosuppresant
drugs are covered for three years. You might lose your coverage
after three years.
Elderly
— We want to go back and see how we are doing with older
patients. Do co-morbidities increase risk? As the population
ages, we have to look at this. Have we created a group of
disadvantaged 18-34 year olds who are not getting organs?
Has the pendulum shifted to older recipients and how has that
harmed the younger patients? ECD also comes into play here.
- Recommendation:
Assess how co-morbidities affect risk and the access younger
people have to organs (i.e., 18-34 year olds).
Diabetics
— Which ones are dying on the list? Are there healthy
diabetics out there with a lower risk of death? Are there
ones who are dying on the list when they aren't really eligible
for transplant? They could be disadvantaged; then we have
to address it. If they have a higher risk of death, we need
to know that.
- Recommendation:
Explore whether there is a class of diabetics on the list
who are ineligible for transplant.
Sollinger
— Do you think there is a substantial number of diabetics
who are on the list who are not eligible for transplant?
Young
— We don't know, but we should find out.
Full
Committee Discussion of the Fair Treatment Subcommittee Report
and Recommendations
William
Harmon
Harmon
presented seven areas, which this Subcommittee plans to discuss
with the goal of bringing back recommendations to the full
committee:
Seven
areas:
- Nondirected
donors
- Pediatric
issues
- Quality
of life
- Extended
criteria donors
- Organ
refusals, including paybacks
- Minimal
listing criteria
- Unfairly
treated groups.
Nondirected
Donors
Harmon
identified three types of nondirected donors: voluntary offer,
living donor swap, and a swap with the deceased donor list.
Evaluation of the donor candidate would be done by donor hospital
and would include a psychiatric/psychological component and
a determination of whether coercion or payment occurred. The
other components are no different from those of the usual
donors, although a more extensive psychiatric/psychological
evaluation may be involved.
Regarding
the choice of donor hospital, it is critical to maintain primacy
of donor preference. When there is a swap, the donor must
go where the transplant is occurring. It is up to the donor
hospital to approve that donor. No donor may be forced upon
the hospital. The determination of where the donor is going
to be operated on should be no different from any other type
of operation.
Allocation
questions must also be addressed: Should a nondirected organ
go to a hospital versus a consortium of hospitals versus the
OPO versus the region. The allocation must be regulated and
not left up to the individual hospital. The most economical
way would be to follow the deceased donor list for that locality
to avoid prolonged cold ischemia times. Designation to a group
would probably not be ethical. A long discussion ensued about
whether a donor should be able to designate to a child. We
may be able to develop a logical and ethical basis that suggests
that children are a special group.
Should
the responsibility for donor follow-up fall to the donor hospital?
This follow-up may be a research opportunity.
Pediatric
Issues
There
was some discussion on preparing a background paper on society's
treatment of children including an ethical perspective, OPTN
history, and the principle of preference in allocation.
Regarding
children as donors, it was noted that many children are deceased
donors. We need a position statement about using
children as living donors. Delmonico and Harmon
have written a paper on 40 children who were used as donors.
Some controversy
exists about clinical trials in pediatric transplantation.
Some attempts have been sabotaged by groups that do not want
to include children in studies. We also need more information
about what happens to pediatric recipients as they make the
transition to adulthood. For example, who should be monitoring
how they do? What happens when they exhaust their coverage
for immunosuppressive drugs?
Quality
of Life (QOL)
- QOL
is an outcome variable of organ transplantation. What are
measures of QOL (biological, sociological, psychological,
economic, family, burden)?
- Tools
for measuring QOL: There are some specific issues about
whether the usual QOL tools apply to transplant patients.
- What
is the purpose of studying QOL?
- We
already have lessons from MELD/PELD. Are we ready for an
outcome-based (benefit) allocation system?
- Outcome-based
allocation may reinforce current outcomes. (The rich get
richer.)
Extended
Criteria Donors
- The
definition of ECD insofar as kidney donation is clear.
- ECD
for liver donation: Propose an SRTR study to
determine threshold of viability of ECD. Eighty percent
of ECD livers are from DCD and donors that yield single
organs.
- Allocation
of ECD organs: If we cannot place them, is it worth recovering
them in the first place?
- Balance
of organs per donor versus ECD. Are OPOs penalized for single
organ ECD? There are financial disincentives for using ECD.
- Additional
cost of transplanting organs from ECD is a penalty (differential
recovery reimbursement).
Organ
Refusals, Paybacks
Harmon
posed the question of whether the payback system is bankrupt.
He mentioned an SRTR/OPTN study. Better data are now being
collected by the new UNOS system to document reasons for organ
refusal. He also brought up issues around ECD and DCD organs
and mentioned that the extra time needed for placing organs
through the payback system compromises their viability.
Minimal
Listing Criteria
- Reserved
for liver transplant listing
- Review
of current OPTN proposal:
- MELD
score less than 10
- Regional
review boards and exceptions (variable)
- Balance
of minimal listing versus broad sharing: SRTR has already
looked at this issue. The Subcommittee will seek data in
this regard.
Unfairly
Treated Groups
Harmon
listed the following groups as among those that may be unfairly
treated:
- Minorities:
We need to follow up on SRTR data.
- Women:
less likely to get listed or transplanted
- Insurance
groups
- The
elderly
- Diabetics.
ACOT
Waitlist Subcommittee (C)
Breakout Session
Members
Nancy
Ascher
Frank Delmonico
Hal Helderman
Bob Higgins
Diana Lugo-Zenner
Jim Perkins
Mike Seely, chair
Hans Sollinger
Mike Seely
opened the meeting and suggested that the discussion would
lay the groundwork for the upcoming meeting in November. He
introduced three areas for discussion:
- Burden
of disease
- Management
of the kidney waitlist
- Heart
utilization.
Burden
of Disease
It was
pointed out by members of the Subcommittee that this topic
has some political edges that should not be ignored. The data
must be closely examined.
Fritz
Port from the SRTR started the discussion about comparing
ECD and standard (kidney) transplants. He suggested it was
important to look at what happens when the transplant is performed
as opposed to when it was not performed. Upon receiving an
offer of an ECD organ, the patient asks his or her doctor,
"What alternative do I have?" After the discussion,
they either decide not to receive a transplant, or they don't
accept the one that's being offered and decide to wait for
the next one. The key issue is the probability of receiving
a good organ, not whether it's an ECD organ.
Key comment:
Once an allocation is available and the call goes out, the
person receiving the transplant has to decide whether to take
it, or wait for another organ. There was some discussion about
the OPO wait time. If the DSA wait time is short, it is more
likely that a patient may elect to wait for a non-ECD kidney,
whereas a DSA with a long wait time would compel the recipient
to elect to take the initial ECD offer.
Jim Perkins
concurred with the fact that a short waiting time would likely
motivate the patient to wait for a better kidney.
Fritz
Port responded that it depends on what part of the country
you're in. With ECD you take the offer vs. waiting & try
to separate allocation and acceptance questions. These are
two different questions: (1) who gets the offer and (2) whether
it's an ECD issue.
Henry
Krakauer reviewed the elements of the multiple outcomes model,
which encompasses five domains including mortality, psychological
distress, and morbidity. A key notion to consider is whether
or not we allocate based on results. Port suggested that in
some way this is a consideration for kidney allocation.
Russell
Wiesner stated that when we discuss burden of disease issues
there's a strong possibility of "gaming." Currently,
we're open for a great deal of subjectivity — everyone
is doing whatever they have to do to support their patients.
Allocation can't be dependent upon subjective measures.
There
seemed to be consensus about looking at the burden of disease
model in parallel with the model that is currently in place
Analysis
of the MELD system shows that the three most important variables
are:
- Age
- Race/ethnicity
- The
transplant center.
It would
be great to have a system that was based entirely on objective
measures, but, how do we do it? It's very complex (e.g., you
can't use age as the sole criterion).
Mike Seely
related a conversation with Larry Hunsicker about how more
information is preferred to less as decisions are made on
behalf of patients.
Wiesner
responded that it is a great concept Hunsicker is advancing,
but there's still a need to look for more objective measures.
Henry
Krakauer asked to what extent is it legitimate to use treatment
as a predictor of outcomes? Is it morally sound to continue
working with transplant centers that show poor results at
the expense of those that are doing well?
Wiesner
noted that the data that is currently being used is old —
perhaps up to 2-3 years old. Is it right not to work with
a center because of old data? Maybe they have some new surgeons
now, or the old transplant team has departed. In these cases,
the "old" data become useless.
Henry
Krakauer asked, "What interventions are we using now
to offset unworkable center policies, or the skill levels
of the medical/nursing team? You must look at these variables,
closely (although it may not be fair). It's a philosophical
question that we return to again and again."
Diana
Lugo said that this is all good discussion, but the Subcommittee
doesn't have to address it now.
Someone
mentioned SRTR data and how it is very familiar to patients
now. Even the payors may stop using centers with a poor record
of performance (i.e., minimal success rate).
Wiesner
said that the most important consideration for third-party
payors is cost.
Seely
agreed that for both payors and providers the bottom line
is most important. Of course, they want excellence, but there
is a strong interest in driving down costs, as well.
Weisner
cautioned about using data on the rate of re-transplantation
as a measurement of quality. At the end of the day, saving
patients and assuring their survival is the key measure.
Seely
asked about the importance of the data related to uniformity
of liver biopsies and how are we tracking what happened to
these organs.
Frank
Delmonico asked where the statisticians are taking this discussion
(i.e., policy focus based on data collection and analysis
thus far). Krakauer responded that the approach for determining
if a transplant should occur is driven by an attempt to understand
two issues: patient benefit and patient harm. Also important
is the patient's prognosis and what can be done to optimize
the prognosis. The second question is the most important.
The next
question is how to optimize the prognosis by analyzing the
five domains in the multiple outcomes model. Krakauer cited
some examples using the Karnofsky score as a strong predictor
of success. With respect to the burden of disease, there is
definitely a need to come up with a system that offers better
opportunities for auditing and minimizes opportunity for "gaming."
Although he added, "You can't ignore subjectivity; invariably
it will be part of the process."
Another
issue that is being closely examined is this: How does all
of this relate to better patient management? Whether to use
a standard organ or an ECD organ for a transplant has bearing
on patient management factors (morbidity, psychological distress,
etc.)
Kress
suggested that all of this talk regarding the details of how
things get measured suggests we can come up with a better
way to measure outcomes. Weisner said in regard to the Karnofsky
score and so forth that it's important that we don't try to
reinvent the wheel.
Delmonico
agreed with all of this, but he wanted to know what can be
done to manage the waitlist. Krakauer added that there are
only so many organs for allocation and suggested that as a
result only the person that is most likely to have the greatest
amount of benefit should have a transplant. And, those that
are least likely to benefit from a transplant shouldn't be
on the list.
This dialogue
led to more discussion about waitlists and how it remains
increasingly important to view kidney transplants separately
from heart, lung, and liver transplants. The individual who
needs a kidney doesn't have the burden of making a life-or-death
decision that is forced upon a heart or lung transplant patient.
In the end, it's important to think in terms of transplant
benefit (survival and quality of life issues with or without
a transplant).
Port said
that, based on the organ transplant needed, from a waitlist
perspective, the Subcommittee might consider the following:
- Lung
& Heart: urgency and transplant benefit
- Liver:
urgency is the main consideration. (Seely suggested that
gaming is reduced when the transplant decision is categorized
as a benefit, or not urgent.)
Everyone
agreed that at all costs "gaming" must be prevented,
but there was ongoing discussion regarding how to establish
criteria that would prevent chaos. There were some comments
about the degree of benefit (in liver transplants?) and the
ongoing need to develop outcome measures for this procedure
similar to those that helped drive decisions associated with
lung transplants. The conversation returned to factors that
currently impact outcomes for non-liver/heart transplants:
age, race and the performance of medical teams in the transplant
center.
Krakauer,
Weisner, and Kress continued by discussing issues related
to (1) analyzing posttransplant data, (2) models that may
be superior to MELD, and (3) how existing data on the transplant
centers have not been looked at, or routinely collected. One
participant mentioned how the data should be evaluated based
upon the organ transplant (i.e., organ-specific analysis).
Everyone agreed that the urgency (or benefit)
issue depended upon the organ involved and that the Subcommittee
should think about developing principles and presenting them
to UNOS. All agreed that the approach should be organ-specific.
Krakauer
suggested that the lung allocation model clearly demonstrated
that patients did have an improved quality of life. His comments
were not accepted well by one participant, a living lung donor
who was participating in the discussion. She felt that lung
transplants were too traumatic and didn't add anything to
the patient's quality of life, labeled the procedure "medical
experimentation," suggested that surgeons were making
lots of money by doing this procedure, and said that children
who receive lung transplants suffered disproportionately.
There
some mention of the Vanderbilt study on quality of life for
transplant recipients.
The discussion
moved to kidney transplants. Everyone agreed they are beneficial
and that more information on these benefits is needed and
important. Then there was discussion about OPTN goals and
whether or not the key issue should be survival, equity, waiting
time, or quality of life.
Someone
suggested that the committee establish a goal and then put
into place the science that helps meet the stated objectives.
There
followed a discussion about the impact on different ethnic
groups. Port believed that equity was not an issue for lung
transplants. Krakauer suggested the grounds for allocation
might meet the following guidelines:
- Liver
transplant: Survival
- Lung
transplant: Survival & disability
- Heart:
Morbidity
- Kidney:
Not disability, but morbidity and mortality.
General
comments following this discussion included these:
- There
is a mix of data from which the assessment should be made.
- Survival
benefit or a reduction in disability may override a slight
increase in mortality.
- Start
with the specific data and then use aggregate data to form
judgments.
- The
selection of criteria and methods must be flexible.
- Impact
on the patient is critical (what is the prognosis, political
issues, policy decisions).
- "Kill
me or cure me" (how to look at the often circumstantial
decision analysis associated with offering an organ and
the individuals choice to accept-do they want to live longer?).
- In
the real world there are random events that have an unpredictable
impact upon survival rates
One of
the "public" participants stated, "Patients
don't care. They want the organ and at the time of the transplant
they don't care about options."
Managing
the Kidney Waitlist
The group
turned to the question of what needs to happen in order to
manage the kidney wait list. It was noted that
there has been a dramatic drop in heart transplants. We should
apply the "lessons learned" to develop similar methods
of allocation for lung, liver, and kidney transplants.
The
group recognized that the kidney waitlist is out of control
but had different opinions about how to fix it. Delmonico
suggested the committee turn to the experts (Port and Krakauer)
for help. He asked them to talk about the benefit of transplants
vs. the disadvantages of being on a long waitlist.
Port observed
that all patients received benefit from transplantation, but
those over age 65 shouldn't have a transplant. The sicker
patients have a greater benefit than the healthier patients.
Delmonico
added that the goal should be a more realistic
kidney wait list and suggested the committee look more closely
at the discrepancies of getting on the list. Port mentioned
that removing older and sicker patients would reduce the wait
list.
There
followed a long discussion about using time on
dialysis as the key determinant. Fritz Port added that the
longer a patient is on dialysis there is a decrease in benefits
of a transplant. He suggested that the average wait from start
of dialysis to transplant is the same. Wiesner wanted to know
if you save more people on the front end and Port noted that
there is equalization over time.
Wiesner
wanted to know ACOT's stance regarding using time on dialysis
as a basis for accruing waittime, and there was agreement
that equity is important, although moving to a
system where dialysis is used as a key determinant for transplantation
might have a disproportionate impact on African Americans.
There
was discussion about
- Simulation
models (the waitlist, time waiting for an organ, start of
dialysis);
- Outcomes
for minorities (worse, overall);
- Possibility
of accepting the fact that harm may occur at the expense
of better distribution; and
- This
criterion might also lead to a longer waitlist.
Krakauer
summed up the discussion by suggesting the committee should:
- Be
clear about what it wants to accomplish;
- Determine
if the policies help achieve the objective; and
- Assess
if the policy can be implemented without harming a particular
subset of the target population.
Seely
suggested that weighing harm vs. systemic outcomes could lead
to better management of the kidney waitlist.
Delmonico
mentioned that managing the wait list depended on some additional
factors, such as:
- Preparing
the patient (are they ready for a transplant?).
- Developing
more effective systems to track who is on the list and whether
they are ready for a transplant.
Seely
agreed the waitlist might be reduced if there were:
- More
information collected regarding the status of the patient
when the offer of an organ is made.
- At
time of listing there was a way to ensure that the patient
was ready for a transplant (i.e., no adverse circumstances,
or conditions).
He also
suggested that oftentimes there are patients on the waitlist
who haven't made a visit to a transplant center and they're
just on the list accruing wait time.
This was
followed by discussion about eliminating gaming. Would switching
to time of dialysis keep it to a minimum? Delmonico mentioned
patients don't gain wait time on the list in Region 1 unless
they're on dialysis.
There
was extensive discussion about death on the list and death
with a functioning graft — how this may exceed rejection
as the cause of graft loss. Some in the group felt this would
be a notion the public would find acceptable
Seely
asked the group's opinion regarding the notion of minimal
listing criteria. Some felt it was like rationing, but this
may be something that can't be avoided given the availability
of kidneys. Everyone felt something needed to be done to assist
health care providers in making better judgments regarding
when a patient gets on the wait list.
There
were other suggestions for minimizing the wait list. Krakauer
said the committee should (first) clearly state
the objectives (what will be gained by employing
the new strategy for reducing the wait list).
Delmonico
reminded the group that it is not necessary to make a recommendation
at this meeting. However, everyone seemed to agree that using
time of dialysis as a determinant might help decrease the
number of individuals on the wait list. It was a suggestion
that most felt was reasonable and an example of multi-variant
modeling that may prove effective for managing the kidney
wait list.
Seely
led a discussion regarding an April 22, 2004, summary of a
"Heart Organ Utilization Roundtable Discussion"
held at Rush University Medical Center (Chicago, Illinois).
After
some lively discussion about the content of the memorandum
the breakout session came to an end.
Full
Committee Discussion of the Waitlist Subcommittee Report and
Recommendations
Michael
Seely
Seely
identified three areas of focus: (1) burden of disease; (2)
management of the kidney waitlist; and (3) the problem of
heart utilization.
Burden
of Disease
Seely
suggested that this topic may be more appropriate for the
Quality of Life Subcommittee. He explained that allocation
programs may have to be differentiated on the basis of different
organs. With livers, for example, we have moved to a medical
urgency model (MELD/PELD). In our discussions, we may wish
to define a set of principles to guide discussions.
Kidney
Waitlist
The kidney
list is ever-expanding. The driver, in this case, is waiting
time. The Subcommittee discussed using dialysis
as a starting point. The group was pretty much equally divided.
There was some discussion of fairness issues. What can be
harnessed from some multivariant modeling? Fritz Port gave
some insights about applying a MELD-type system to kidneys.
We should start to look into this so we can see if we need
to consider alternatives.
Heart
Utilization
Heart
utilization rates vary by DSA (17% to 47%). The waiting time
for hearts has decreased dramatically. A central issue is
donor management. Are there efforts made to resuscitate
and improve donors? We need to look at practices in different
regions and conduct some peer reviews in low-yield DSAs. What
is going on in these areas? Does the size and number of programs
in a DSA affect utilization rate? Fritz Port suggested doing
some modeling to calculate lives benefited. It may be possible
to look at different-sized cutouts in different areas to see
what happens.
Bob
Higgins brought up the idea of a consensus conference to look
at this problem.
Solarz
asked if there had been thought to the concentric circle model
because coastal areas are disadvantaged. Merion said that
SRTR presented a family of models that look at effects of
different allocation sequences and systems. What would be
the effect if you allocate hearts to highest status patients
locally? The model showed notably fewer deaths. One caveat:
the models do not have a way to account for cold ischemia
time. Within a 500-mile radius we would be within the safe
4-5 hour cold ischemia time for hearts. For lung, we tried
to balance benefit-urgency model. You must be somewhat careful
in these modeling exercises because there is not a good way
to predict how behavior might change if listing/utilization/allocation
changes. Unexpected, further changes may result. We have to
use expert opinion to try to predict what might happen.
Seely
said that we need to see what is going on in low-utilization
areas. Higgins noted that fewer than 50% of consented hearts
are utilized. This is a call to action for the thoracic community.
Public
Comment and Closure
Carol
Brotman addressed the Committee. She donated part of her liver
to her husband 23 months ago. Her interest is advocacy with
other people. In the State of Rhode Island, one senator has
been moved to get involved in transplantation. Two bills have
been introduced, one of which parallels Wisconsin's bill.
The state is thinking to set up a trust fund to help pay for
treatments for treating adverse effects of drug therapies.
She is also interested in looking at issue of valuable consideration
and the possibility of paying for related, nonmedical expenses
for living donors. Assisting with expenses is very important.
Mary Ganikos
spoke about the curriculum for driver's education classes,
which is completed and will be printed shortly. It will be
available on CD as well. That project has been completed except
for dissemination and implementation. The package is available
on the Division of Transplantation's Website: www.organdonor.gov/student.
Nancy
Ascher then made a presentation to Jack Kress of a placque
from all of the members of ACOT, which read as follows: "HHS
Advisory Committee on Organ Transplantation (ACOT) commends
Jack Kress for his exemplary performance and significant contributions
in serving as ACOT's first Executuve Director from 2000-2004."
The members
of the Committee then gave Mr. Kress a standing ovation and
the meeting adjourned.
