Factors associated with perceived donation-related financial burden among living kidney donors

The perception of living kidney donation–related financial burden affects willingness to donate and the experience of donation, yet no existing tools identify donors who are at higher risk of perceived financial burden. We sought to identify characteristics that predicted higher risk of perceived financial burden. We surveyed 51 living kidney donors (LKDs) who donated from 01/2015 to 3/2016 about socioeconomic characteristics, predonation cost concerns, and perceived financial burden. We tested associations between both self-reported and ZIP code–level characteristics and perceived burden using Fisher's exact test and bivariate modified Poisson regression. Donors who perceived donation-related financial burden were less likely to have an income above their ZIP code median (14% vs. 72%, P =.006); however, they were more likely than donors who did not perceive burden to rent their home (57% vs. 16%, P =.03), have an income <$60 000 (86% vs. 20%, P =.002), or have had predonation cost concerns (43% vs. 7%, P =.03). Perceived financial burden was 3.6-fold as likely among those with predonation cost concerns and 10.6-fold as likely for those with incomes <$60 000. Collecting socioeconomic characteristics and asking about donation-related cost concerns prior to donation might allow transplant centers to target financial support interventions toward potential donors at higher risk of perceiving donation-related financial burden.
