Abstract
AbstractIntroductionThis study evaluates the implications of drug intoxication (DI) on donor utilization and outcomes in liver transplantation (LT).MethodsThe UNOS STAR database was evaluated for all potential donors and adult, first‐time, whole LT between 2005 and 2019. Logistic regression analyses evaluated liver utilization; proportional hazards modeling assessed risk of 1‐year graft loss.ResultsA total of 132 783 potential donors (10 205, 7.7% from DI), and 90 612 adult LT were identified (7490, 8.3% from DI). DI donors had median age 32 years (IQR 26–40 years, p < .001), were 42.6% female (n = 4346), and 15.5% were DCD donors (n = 1583). Utilization of DI donors changed over time, such that by 2015–2019 they were the most likely donor cause of death (COD) to be utilized. Among LT recipients, there were insignificant differences (<2% variance) in age, gender, ethnicity, and etiology of liver disease according to donor COD. Recipients with MELD scores >30 more frequently received grafts from donors with trauma (23.8%) and DI (21.8%) versus cardiovascular (20.0%) and CVA/stroke (19.9%, p < .001). Among DBD donors, DI‐COD was associated with superior 1‐year graft survival compared to donors from trauma (HR 1.172, 95% CI 1.057–1.300) and CVA/stroke (HR 1.404, 95% CI 1.264–1.561, p < .001). Donor COD was not significantly associated with 1‐year graft loss among DCD donors.ConclusionsThere is an increased likelihood of donor utilization when COD is drug overdose and an increased likelihood of 1‐year graft survival compared to donors from trauma, CVA/stroke, and other COD.
