BACKGROUND & AIMS: Racial/ethnic disparities in liver transplantation (LT) are well-recognized. Although Hispanics represent the largest and youngest minority group in the United States, limited data exist on long-term outcomes. We aimed to investigate long-term post-liver transplant outcomes in Hispanic patients and identify potential disparities compared to a baseline demographic of non-Hispanic white patients. METHODS: We performed a retrospective cohort study of first-time liver transplant recipients using the United Network for Organ Sharing database from 2002 to 2013, with follow-up through 2018. The primary outcomes of interest were overall patient and graft survival after LT. RESULTS: 45 767 patients underwent LT (85.0% non-Hispanic white, 15.0% Hispanic). Hispanics had lower socioeconomic status, higher prevalence of pretransplant comorbidities and more severe liver disease compared to non-Hispanic whites. Hispanics had similar patient (76.6% vs 75.6%; P = .12) and graft (71.7% vs 70.8%; P = .28) survival at 5 years and significantly better patient (62.9% vs 59.7%; P < .001) and graft (58.6% vs 55.6%; P = .002) survival at 10 years. In multivariable analysis, Hispanics had lower associated all-cause mortality (HR 0.86, 95% CI, 0.82-0.91; P < .001) and graft failure (HR 0.89, 95% CI, 0.85-0.93; P < .001) compared to non-Hispanic whites. In etiology-specific subanalysis, Hispanics transplanted for ALD, NASH and HCV had lower all-cause mortality compared to non-Hispanic whites. CONCLUSIONS: Hispanics have similar or better long-term post-LT outcomes compared to non-Hispanic whites despite a worse pretransplant risk factor profile. Further research is needed to clarify if this survival advantage reflects uncaptured protective factors or more stringent transplant selection in the Hispanic population.
