Psychological characteristics of candidates for liver transplantation: differences according to history of substance abuse and UNOS listing. United Network for Organ Sharing.

Liver transplantation for patients with a history of substance abuse remains controversial. Resumption of heavy alcohol use postoperatively is a threat to long-term survival, but recidivism among transplanted alcoholics is reportedly low. An argument against psychological evaluation prior to transplantation revolves around the speculation that candidates will attempt to portray themselves as more desirable prior to listing with UNOS (United Network for Organ Sharing). This study measured psychological distress, coping styles, optimism, selected personality features, and perception of family environment among 73 U.S. military veterans who were candidates for liver transplantation. Candidates with positive histories of substance abuse revealed significantly more distress, less adaptive coping styles, and more character pathology than their counterparts. The only significant difference according to UNOS listing was on one measure of family environment. Results support preoperative psychological assessment and intervention on a more extensive level for substance abusers and raise questions for future research.
