A Meta-Analysis on the Incidence of Donor Related Depression after Liver Transplant.

Abstract

AIM\nLiving donor liver transplantation (LDLT) is increasing, yet gaps exist in the understanding of psychological wellbeing of donors after liver transplant. This meta-analysis seeks to evaluate the incidence and risk factors for donor-related depression after liver transplantation.\n\n\nMETHODS\nA search was conducted on Medline and Embase database. Articles assessing incidence of depression in LDLT donors were included. Incidence was pooled after Freeman-Tukey double-arcsine transformation. For risk factors, dichotomous variables were analyzed with generalized linear model while a conventional meta regression with logit transformation was conducted for continuous variables.\n\n\nRESULTS\nOf 1,069 abstracts, 40 articles underwent full-text review. 17 articles were included. The pooled incidence of depression among 1,888 LT donors was 7.66% (CI: 4.47% - 12.80%). Depression rates were significantly higher in Asian compared to Western studies (RR: 1.73, CI: 1.19 - 2.52, p=0.0039). Female gender (p<0.001), Caucasian ethnicity (p=0.047), employment status (p<0.001) and lower education levels (p=0.044) were significantly associated with depression. Donor relationship with recipients was not a significant risk factor.\n\n\nCONCLUSIONS\nLDLT remains a core aspect of the treatment of end-stage liver disease. However, the high depression rates after LT suggest that there remains room for improvement in the care of donors mental health post-transplant.
