Abstract
BACKGROUND: Elderly patients are evaluated for liver transplantation (LT) with increasing frequency, but outcomes in this group have not been well defined. METHODS: A linkage of the Scientific Registry of Transplant Recipients (SRTR) and the University HealthSystem Consortium (UHC) databases identified 12,445 patients who underwent LT during 2007-2011. Two cohorts were created consisting of, respectively, elderly recipients aged ≥70 years (n = 323) and recipients aged 18-69 years (n = 12,122). A 1:1 case-matched analysis was performed based on propensity scores. RESULTS: Elderly recipients had lower Model for End-stage Liver Disease (MELD) scores at LT (median 15 versus 19; P < 0.0001), more often underwent transplantation at high-volume centres (46% versus 33%; P < 0.0001) and more often received grafts from donors aged >60 years (24% versus 15%; P < 0.0001). The two cohorts had similar hospital lengths of stay, in-hospital mortality, hospital costs and 30-day readmission rates. There were no differences in graft survival between the two cohorts (P = 0.10), but elderly recipients had worse longterm overall survival (P = 0.009). However, a case-controlled analysis confirmed similar perioperative hospital outcomes, graft survival and longterm patient survival in the two matched cohorts. CONCLUSIONS: Elderly LT recipients accounted for <3% of all LTs performed during 2007-2011. Selected elderly recipients have perioperative outcomes and survival similar to those in younger adults.
