Liver and intestine transplantation: summary analysis, 1994-2003

Abstract

With nearly two years of data available since the inception of the MELD and PELD allocation system, this article examines national OPTN/SRTR data to describe trends in waiting list composition, waiting list mortality, transplant rates, and patient and graft outcomes for liver transplantation. Following a 6% reduction in the size of the waiting list after MELD was implemented in 2002, the number of patients on the waiting list grew by 2% from 2002 to 2003, while the number of liver transplants increased by 6%. The overall death rate while on the liver waiting list has decreased from 225 deaths per 1,000 patient years in 1994 to 124 deaths in 2003. As with the waiting list death rates, post-transplant death rates have also decreased over the past decade. Unadjusted one-year patient survival was lower for older donor age groups (88% for donors aged 18-34, 87% for donors aged 35-49, 85% for donors aged 50-64); a similar trend was observed at three and five years following transplantation. Intestine transplantation is performed with slowly increasing frequency and success. Early graft losses and rejection rates have changed little since 1994, but rejection is easier to control and long-term survival is improving.
