Disparities in organ allocation and access to liver transplantation in the USA

Abstract

Liver transplantation has become the standard of care for the treatment of chronic liver disease. In 1986, the United Network for Organ Sharing (UNOS) was formed to ensure the just and equitable allocation of donor livers. At the time, UNOS decided to use the Childs–Turcotte–Pugh scoring system to determine the degree of liver disease in potential transplant patients. Unfortunately, it was shown that the Childs–Turcotte–Pugh system was easily manipulated and did not provide equal access to donor organs. Owing to this fact, the Model of End Stage Liver Disease (MELD) score was instituted by UNOS in February 2002. While the institution of MELD has shown an improvement in organ allocation and outcomes, disparities still exist. This article discusses UNOS and the MELD allocation system as well as the racial, geographic and gender disparities that occur despite the institution of the MELD system.
