Satisfaction with life and depressive symptoms in living organ donors and non‐donors: new insights from the National Living Donor Assistance Center

BACKGROUND: Previous studies indicate there may be psychological consequences of being unable to serve as a living donor, but these have not been explored in a large national cohort of low-income individuals who initiated living donor evaluation in US transplant centers. METHODS: Using data from 6574 National Living Donor Assistance Center (NLDAC) participants (November 1, 2007-December 31, 2018), we utilized a cross-sectional study design to evaluate short-term depressive symptoms and satisfaction with life in living donors and non-donors (those who were declined or withdrew from evaluation) using the Satisfaction with Life Scale and the PHQ-8, with and without risk adjustment using linear regression. RESULTS: National Living Donor Assistance Center participants originated from 207 US transplant centers. 52% of NLDAC participants responded to the survey (n = 3423; donors = 2848 (58.6% of all donors), non-donors = 575 (33.5% of all non-donors); ncenters = 201)). Respondents were significantly older, more likely to be female, white, non-Hispanic, married, more educated, more full-time employed, and more likely to be unrelated to the recipient vs non-respondents (all, P < .001). Among survey respondents, donors were significantly younger, more likely to be non-Hispanic, employed, and related to the recipient compared to non-donors (all, P < .05). Higher PHQ-8 scores were correlated with lower SWL scores (r = -.32, P < .001). Both groups displayed high SWLS (donors vs non-donors: 27.1 vs 26.3, P = .002). Both groups had low levels of depressive symptoms overall, but donors had more symptoms than non-donors (3.5 vs 2.4, P < .001). After risk adjustment, non-donors had significantly less depressive symptoms by PHQ-8 (28% lower, P < .001), but had lower life satisfaction (1.2 points lower, P < .001). CONCLUSIONS: Donors and non-donors have high global levels of overall life satisfaction and low levels of depressive symptoms at 8 weeks after donation or denial. While small effect sizes were observed between groups in these outcomes, being a non-donor was an independent risk factor for lower life satisfaction, which warrants further evaluation.
