Predictive value of psychosocial assessment for the mortality of patients waiting for liver transplantation

Selecting suitable candidates for liver transplantation is the most challenging task of pre-transplant evaluation. In addition to somatic assessment, psychosocial evaluation has been proven important in identifying patients at high risk of potential failure. The Transplant Evaluation Rating Scale (TERS) is a widely used rating instrument for the assessment of psychosocial risk factors before liver transplantation. The aim of this study was to explore the predictive value of TERS for mortality in liver transplant patients before and after transplantation. The medical records of patients referred for psychiatric evaluation before liver transplantation between 2003 –2013 were analysed. Administering TERS was part of the pre-transplant evaluation. The TERS scores of patients who died before and after transplantation were compared with those who survived following transplantation. One hundred and sixteen patients were referred for pre-transplant psychiatric evaluation. Patients with successful liver transplants scored significantly lower on TERS than those who died before transplantation (30.65 ± 6.06 vs. 34.75 ± 8.25, p = .031). Patients who died after transplantation scored significantly better on TERS than those who died before transplantation (28.79 ± 2.81 vs. 34.75 ± 8.25, p = .003). There was no significant difference between the deceased and surviving transplanted patients’ TERS scores (28.79 ± 2.81 vs. 31.19 ± 6.66, p = .365). TERS appears to be a suitable rating instrument to help select candidates who have higher chance to survive prior to transplantation but it could not predict post-transplant mortality.
