Post-operative outcomes in anonymous living liver donors: What motivates individuals to donate to strangers.

Abstract

Anonymous living donor liver transplantation (LDLT) is a strategy to address the shortage of available transplantable livers; however, few studies have been conducted on this population. The objective of this study was to describe the motivations and medical, psychosocial, and financial outcomes of anonymous living liver donors. Between 2010-2019, 116 anonymous living liver donors were evaluated, 59 (51.7%) of whom proceeded to surgery. A subset of 21 anonymous donors were matched to biologically/emotionally related donors according to age, gender, race, and duration since surgery. A medical chart review and post-surgical interviews were performed to assess medical and financial outcomes. The primary motivation for donors was an unselfish desire to help others (43, 72.9%). A total of 13 (22%) anonymous donors experienced complications. Of these, 7 (11.9%) were grade I Clavien-Dindo classification, 5 (8.5%) grade II, 1 was grade III (1.7%); and no patients had grade IV-V Clavien-Dindo complications. Increased anxiety was reported by 3 (5.1%) donors, and one donor reported clinical levels of depression (1.7%). Within the matched controls, anonymous donors were not significantly different to biologically/emotionally related donors with regard to surgical complications, psychosocial, or financial outcomes. Allowing a greater number of anonymous donors may facilitate the reduction of the waitlist for liver transplant candidates.
