The impact of race on liver transplant outcomes in the MELD era: still more questions than answers.

Liver transplantation is a life-saving therapy for patients with end-stage liver disease (ESLD); however, donor livers are scarce. Several studies have demonstrated racial disparities in access to liver transplant as well as patient and graft survival after liver transplantation. These studies used data gathered before the model for end-stage liver disease (MELD) was used to determine priority for liver transplant. In this issue of the journal, Drs. Ananthakrishnan and Saeian examine survival after transplant in the MELD era by race and ethnicity, and show that the racial disparities in posttransplant outcomes persist despite MELD. This study provides further evidence that race, which is likely a proxy for a variety of biological and sociological factors, must be considered in any prognostic model for liver transplantation. The impact of race on liver transplantation outcomes should be evaluated further in a well-designed, multicentered, prospective study.
