We examined prospectively determined psychosocial evaluation data in 125 consecutive adult patients undergoing heart transplantation from January 1992 to April 1994 to determine their associations with morbidity, mortality, and compliance. Prospective ratings included age, sex, weight, education, social support, living arrangements, motivation, knowledge and expectations about transplantation, intercurrent social stressors, substance abuse, personality disorder, cognitive impairment, other psychiatric disorders, and the evaluating psychiatrist's global assessment of psychosocial risk. Additional variables evaluated were support group attendance and waiting list time. We examined outcomes including patient survival, compliance, episodes of rejection and infection, development of transplant coronary artery disease, number of missed appointments, and maintenance of ideal body weight. The posttransplant follow-up period was 13.8 +/- 9.9 months (mean +/- SD). In univariate analyses, compliance problems were associated with substance abuse history (P = .0007), personality disorder (P = .007), living arrangements (P = .02), and global psychosocial risk (P = .001). The number of rejection episodes was associated with global psychosocial risk (P = .029), and transplant coronary artery disease was inversely associated with education (P = .01). Survival was not associated with any of the predictor variables. In stepwise multivariate analyses, the significant predictors of compliance were substance abuse (odds ratio 3.69, confidence limits 1.07-12.71) and global psychosocial risk (odds ratio 3.76, confidence intervals 1.18-11.97). These findings suggest that pretransplant evaluation of psychosocial risk factors can identify patients with increased risk of postoperative noncompliance and morbidity.
