Abstract
Context Transplant center performance profiling provides important information for various concerned parties. Comparing a transplant center's performance against the performance of the best-in-class centers may help in understanding the performance thresholds for the underperforming centers. Objectives (1) To identify and describe “Centers for Medicare and Medicaid Services (CMS)-red-flag” performers and the “best-in-class” performers and (2) to examine the relationships between a center's performance profile and outcomes such as 1-year observed mortality, 1-month observed mortality, 1-year risk-adjusted mortality, and volume. Methods The data for analysis was obtained from the published reports on the Scientific Registry for Transplant Recipients (SRTR) website for adult liver transplant programs compiled for the rolling 2½-year cohorts of patients and included 7 cohorts of liver transplant recipients in the study from January through July 1, 2002, through December 31, 2010. We defined 4 performance profiles: CMS-red-flag, lower-than-expected, higher-than-expected, and best-in-class performers. Results The current SRTR methods classify approximately 7% of the adult liver centers as CMS-red-flag performers and 6% of the centers as best-in-class performers in every reported period. Neither of the low-volume centers (<30 liver transplants per 2½-year cohort) was profiled as CMS-red-flag until the 2010 reporting period. The transplant center's profile was significantly associated with the 1-year and 1-month observed mortality rates in every reported cohort ( P < .001). Conclusion The CMS-red-flag profile can be characterized with the following: (1) the highest observed 1-year mortality, (2) the highest observed 1-month mortality, (3) a very large difference between the observed and adjusted mortality rates, and (4) the center volume greater than 30 liver transplants per 2½-year cohort. The SRTR methods are not sensitive for performance profiling in the centers that perform fewer than 30 orthotopic liver transplants per 2½-year cohort.
