title: The impact of MELD on OPTN liver allocation: preliminary results.
abstract: The OPTN implemented a revised system (MELD/ PELD) for the allocation of cadaveric livers on February 27, 2002. When compared with an earlier era, preliminary results indicate that transplant rates remain similar by gender, ethnicity, age group (adult and pediatric) and for most principal diagnoses. Both the actual number of pretransplant deaths and the pretransplant death rate has dropped under the new system. While some regional variation exists in the average MELD scores at listing, death and transplant, it accounts for only a small percentage of the total variation observed. In a multivariate analysis, MELD scores above 20 had the strongest effect and were associated with a significantly increased mortality risk on the waiting list. More data are need to analyze the impact of MELD on posttransplant outcomes.
