The data reported here were prepared by
the Scientific Registry of Transplant Recipients (SRTR) under contract with
the Health Resources and Services Administration (HRSA).
NA=Not Applicable.
1 Transplants during the time period
indicated in the last row of the table. |
| 2
Observed surival rates use the Kaplan-Meier method to estimate outcomes for
patients for whom complete follow-up is not expected; see Analytic Methods
for more details. Because different cohorts are followed for each time
period, it is possible for reported 3-year survival to exceed 1-year
survival. |
3 The
survival rate that would be expected for the patients served by this center,
given the characteristic mix of the recipient and donor (age, disease, blood
type, etc.) and the experience of similar patients in the entire country. See
the Analytic Methods for a description of adjustment and complete list of
adjustment factors.
4
The number of deaths that would be expected during the follow-up time, as
described in footnote 3. Unlike the expected survival percent, the expected
count of deaths reflects the expected number of deaths only during the time
the patient is alive and actually followed; therefore, it accounts for
differences in the time that elapses from transplant until death. |
5 The
95% confidence interval gives a range of values for the true ratio of deaths
at the facility to those expected based on the national experience. The true ratio will be between this lower
and upper bound 95% of the time.
6
A p-value less than or equal to 0.05 indicates that the difference between
the actual and expected patient survival is probably real and is not due to
random chance, while a p-value greater than 0.05 indicates that the
difference could possibly be due to random chance. |
| (a) This difference could plausibly be
just a chance occurrence. |
| 7 Of
days expected to be included in the follow-up period, the percentage of days
covered by follow-up reporting at this center for these transplants. Additional follow-up days included in
survival may be covered by SSDMF data.
This measures the possibility that events such as failure have
occurred without being reported, and it is not a measure of compliance. |
