Evaluation of liver transplant (LT) candidacy involves psychosocial evaluation to ensure appropriate organ allocation. However, the utility of pre-LT psychiatric and neuropsychological factors in predicting posttransplant outcomes remains uncertain. We reviewed current evidence on the prognostic value of pre-LT psychological factors for outcomes after LT. We conducted a systematic review of studies with adult LT recipients that investigate the relationship between pre-LT psychiatric and neuropsychological variables and posttransplant outcomes. We searched Ovid, MEDLINE, PsycINFO, EMBASE/Scopus, Cochrane Controlled trials register and Web of Science (January 1975 to May 2015) for longitudinal, peer-reviewed studies of at least 20 subjects and written in English. The 19 studies included in this review are heterogeneous in population, prognosis and duration of follow-up (from 20days to more than 3 years). Findings on the prognostic value of pre-LT depression or anxiety on post-LT outcomes are mixed, though depression appears to predict lower quality of life (QOL). Pre-LT suicidal thoughts in particular are associated with post-LT depression. High submissiveness may predict rejection within 20days of LT, and low conscientiousness is associated with greater nonadherence. Whereas pre-LT cognitive performance has not been shown to predict survival, poorer performance may predict poorer QOL after LT. Further studies are needed to examine this important element of LT candidacy evaluation. Studies should evaluate psychiatric factors in large samples, include systematic evaluations by mental health clinicians and explore broader neuropsychological domains in predicting posttransplant outcomes.
