Abbreviation: EPTS, Estimated Post Transplant Survival.
a
P value is calculated for trend over year (continuous variable) using a generalized estimating equation.
b
Waiting list volume indicates the total number of patients on the waiting list on day 1 of the fiscal year; waiting list active volume indicates the total active patients on the waiting list on day 1 of the fiscal year.
c
Transplant volume was calculated as the number of transplants during the fiscal year.
d
Local standard acquisition charge for kidney is the standard acquisition charge at the organ procurement organization in the same donor service area as the transplant hospital. Only available for 2013 to 2017.
