Assessing
the Performance of Organ Transplant Programs:
Liver
and Heart Transplantation
In its role
under the National Organ Transplant Act as the responsible steward
of the program of solid organ transplantation in the United States,
the Department of Health and Human Services has carried out analyses
of the three critical issues in transplantation. These are: (1)
What is the likelihood that, having been declared a transplant patient
by being placed on a waiting list, the patient will actually receive
an organ within a reasonable amount of time, say one year? (2) What
is the likelihood that the patient will, instead, die while awaiting
transplantation? (3) And what is the probability that the patient
will still be alive one year after having been placed on the list,
whether or not he or she received a transplant?
The need for
such analyses is highlighted by Figures A (for liver transplantation)
and B (for heart transplantation). These figures present the fraction
of centers (vertical axis) with actual transplant or waiting-list
mortality rates (horizontal axes) and demonstrate the very wide
variation among the centers in the rates of transplantation achieved
for the patients within one year of being placed on the waiting
list. In contrast, the variation in waiting-list mortality rates
is much narrower and more clearly centered around an average or
peak rate. This indicates that, unlike the probability of death,
which is primarily but not solely determined by the clinical condition
of the patient, many other considerations determine the probability
of being transplanted.
This point is
brought out more clearly in Figures C (liver) and D (heart) and
in more detail in Tables A (liver) and B (heart). These tables and
figures present center-specific risk-adjusted rates of transplantation
or of death on the waiting list and the probability of still being
alive overall one year after being placed on the waiting list. The
risk-adjustment corrects, as best the currently available data permit,
for the disparities in the clinical conditions at the time of listing
of the patients accepted as candidates by the various centers.
Despite the
risk-adjustment, a wide variation in center-specific outcomes is
observed. In the case of liver transplantation, 10% of the centers
have a standardized risk-adjusted rate of transplantation within
one year of listing of 24.9% or less, and 10% have a rate of 71.2%
or more. For the probability of dying within a year of listing while
awaiting a liver transplant, the corresponding range is 7.7-22.3%,
and for the probability of surviving one year as a candidate and/or
recipient of the liver transplant the range is 65.3-85.9%. The ranges
of standardized risk-adjusted probabilities for heart transplantation
are: 35.8-71.8% (transplantation), 9.4-23.1% (death while awaiting
a transplant), and 67.0-84.0% (one year survival).
In both liver
and heart transplantation, about two-thirds of the deaths within
a year of listing occur while awaiting the transplant. The two measures
of mortality are strongly correlated, with about 50% of the variation
among centers in risk-adjusted survival accounted for by risk-adjusted
mortality on the waiting list.
In contrast,
there is little correlation between the risk-adjusted rate of transplantation
and risk-adjusted survival, none in the case of the liver. In other
words, a more aggressive transplant policy does not necessarily
achieve better ultimate results. This reinforces the point that
the early performance of a transplant is not necessarily the best
care that can be provided to a patient. The best care consists of
a broad constellation of practices of the listing center and of
other hospitals and care-givers to which the patient is subjected
while awaiting transplantation, as well as during and after the
transplantation itself.
In carrying
out these analyses, the Department identified gaps in the currently
available data collected by the Scientific Registry. Some additional
clinical details about the condition of the patient at the time
of listing will be helpful in improving risk-adjustment. Moreover,
death is not the sole outcome that must be addressed in the evaluation
of transplantation because it is not the sole factor that drives
the care of the patient. A clear understanding of the morbidity
(clinical complications) and of the impairment of the patient's
ability to function before and after transplantation is also indispensable.
For this, the data are currently not available.
The Department,
to fulfill its responsibility for review and oversight of transplantation
in the United States, is currently reevaluating the objectives and
functions of the Scientific Registry. Its goal is to assure that
the Registry carries out on an ongoing and timely basis the assessments
of the effectiveness of the transplant program in sustaining the
life, health and functional capacities of transplant patients, and
of the burdens associated with their care, needed by the Department
and by the transplantation community.
How to Read
the Tables
The objective
of the accompanying tables is to inform persons concerned with liver
or heart transplantation, most particularly the patients, of the
likelihood of three critical outcomes: (a) receiving a transplant
within one year of being placed on the waiting list, (b) dying before
receiving a transplant, and (c) most importantly, still being alive
at least one year after being placed on the waiting list. This information,
which applies to an average candidate, is contained in the columns
labeled Survival, subheaded Alive (at one year), and Experience
on the Waiting List with subheadings Transplanted or Died (within
1 year). The outcomes are presented in two forms, Actual and Adjusted.
The term Adjusted refers to a method for correcting for the differences
in the severity of the illness of the patients taken care of by
the different centers by projecting the center's result, corrected
for the severity of illness of its patients, on a standard population.
If all patients received equally effective care, the centers' adjusted
rates would be identical. The differences among the centers in the
adjusted rates, therefore, reflect the differences in how well the
patients were cared for by the listing center as well as by other
hospitals and care givers who participated in the management of
the patients' conditions.
The first column
in each Table identifies by a code number the Center at which the
patients were registered as candidates for transplantation. The
column labeled Patients gives number of persons listed and provides
an indication of how active that center is. The next two columns
report on the probability of surviving one year after listing, whether
or not a transplant was received - the "bottom line".
The remaining numerical columns provide information on the two principal
alternative events that the patient may experience while awaiting
a transplant - receipt of the transplant or death. A third alternative,
which affects a very small proportion, removal from the waiting
list, was also considered in the analyses. All the patients for
whom data are displayed in these last columns were followed for
at least a full year, hence the cutoff date of December 31, 1997
to permit follow up through 1998. Because of delays in reporting
in the post-transplant period, an earlier cutoff date, December
31, 1996, was needed in the analysis of survival.
The ranges listed
beneath the US averages cover the middle 80% of the centers. Thus,
10% of the centers had rates below the lower end of the range and
10% had rates above the upper end of the range. In the evaluation
of performance, attention should principally focus on the magnitude
of the difference between the center=s result and the US average.
The ranges are provided to help the reader assess how much the experience
of the patients of that center differs from the average.
An additional
indication of the differences among the centers is given by the
+ and - signs to the right of the numbers that signify the rate.
This indication addresses the statistical uncertainty about how
precisely those differences can be measured. The uncertainty is
greatest when few cases or patients are involved and smallest in
the case of the high-volume centers. A single symbol indicates that
the center=s outcome differs from what would be expected with reasonable
certainty (less than 1 chance in 20 that the difference is due to
chance only) and two symbols indicate considerable certainty (less
than one chance in 100). A + sign indicates that the difference
is in a favorable direction (higher probability of transplantation
and of surviving at least one year, and lower probability of dying
while awaiting a transplant), and a - sign indicates an unfavorable
direction (lower than expected probability of transplantation, etc.).
The difference between the result obtained at a center and the national
average, taken together with this measure of uncertainty, is, therefore,
an indication of how distinctively different the experience of the
center's patients is from the national average. (Please note that
the measures of uncertainty apply to a pattern rather than specifically
to the data provided in the Tables. For example, in the case of
Survival, the analyses addressed the pattern of survival for a period
of up to three years, and that is what is reported by the measure
of the level of uncertainty, not just the result at one year given
in the Table.)
How to Use the
Tables
We have produced
the accompanying Tables to draw on recent experience in liver and
heart transplantation to help clinicians to provide and patients
to obtain the best care possible. By describing what happened to
patients following their acceptance as candidates for transplantation
by the more than 100 transplant centers in the US, we hope to enable
(1) patients and their physicians to make more informed choices,
and (2) the transplantation community to more effectively examine
its practices and identify those that offer the greatest benefits
to the patients.
To compare the
experiences of the patients of the various centers, attention should
principally be given to the columns that contain the standardized,
risk-adjusted data. The data for a particular center should be compared
to the national average, given in the first line of each column,
and to the range, given in the second line in each column. The range
provides reference marks to calibrate the degree of concern with
which a center's difference from the national average should be
viewed by giving the results obtained by the middle 80% of the centers,
with 10% of the centers having results below the low end of the
range and 10% above the high end of the range. The columns with
the pluses and minuses give an indication of how (un)likely it is
that the deviation from the national norm could have been due purely
to chance. The pluses and minuses arenot measures of how "good"
or "bad" the centers are. A single plus or minus indicates
a chance of less than one in 20 and two pluses or minus a chance
of less than one in 100. But keep in mind that over 100 centers
are listed in the Tables. That means that for 6 or 7 of them, the
observed deviations could in fact be the result of statistical uncertainty
at the 1 in 20 level, and for 1 or 2 at the 1 in 100 level.
Therefore, although
the data given in the Tables are suggestive, they do not provide
definitive proof of superior or inferior performance. What the data
do clearly demonstrate is that there is,for the very effective life-saving
treatments of heart and liver transplantation, wide variation in
the results achieved at different centers, even after variations
in the severity of illness of the patients of these centers are
corrected for.
We began this
note with the statement that the purpose of the Tables is to help
us learn from experience. We must end with a word of caution. Whether
we draw lessons correctly from experience depends entirely on how
completely and accurately the patients, their severity of illness
and what happened to them are known to us and on how good the analytic
methods that we used are. We are confident about the methods because
they have been well tested over the years. However, because the
collection of the data about the patients and the clinical events
they experience is a complex and arduous task, gaps do exist. In
one extreme example, data on either the height or the weight of
80% of the patients of one center were unavailable, preventing the
calculation in those cases of the body mass index, an important
predictor in several analyses. Depending on how the missing data
were handled in the analyses, the results at that center appeared
either very good or just average. Therefore, the gaps in the data
limit the accuracy of the assessments of performance that we can
produce. We are confident about the pattern of variation that we
observed, but less so about the position of any given center within
that variation. We are currently working with the Scientific Transplant
Registry to fill the gaps in the data and to further improve the
analytic methods so that we may better determine what works best
for patients.
