Disparity in use of orthotopic liver transplantation among blacks and whites

Orthotopic liver transplantation (OLT) is the best treatment for end-stage liver disease. Limited data exist on the access of minorities to OLT. The aim of this study was to determine whether disparities exist among black and white OLT patients. Data were collected from the United Network for Organ Sharing on black and white 18-70 year-old OLT waiting list registrants (n = 29,013) and OLT recipients (n = 15,805) between 1994 and 1998. Standardized transplant ratios were generated by comparing the racial distribution of OLT patients with the US population. Demographic and clinical characteristics of OLT registrants were compared by race. Multivariate analyses were performed to identify predictors of time to OLT and the likelihood of dying or receiving OLT within 4 years, controlling for severity of illness and other factors. The standardized transplant ratio for black OLT recipients (0.65) was significantly lower than the standardized transplant ratio for white OLT recipients (1.05). Blacks were younger and sicker than whites. After adjustment for severity and other factors, time to OLT among recipients did not differ by race (P >.05). Blacks were more likely to die or become too ill for OLT while waiting (P <.001). Blacks were less likely to receive OLT within 4 years (P <.001). In conclusion, adult blacks were underrepresented among OLT patients. Although waiting times were similar once listed, black race affected outcomes while awaiting OLT. The process of referral and evaluation for OLT should be investigated further.
