title: Measuring outcome after liver transplantation: a critical review.
abstract: As the number of liver transplantations performed around the world and the survival rates increase, attention is turning to the broad impact this procedure has on patients' quality of life (QOL), including their physical and psychosocial functioning and their perceived sense of well-being. There exists a small body of literature that examines the global effects of liver transplantation on QOL. The purpose of this article is to discuss the general framework used to assess QOL and to critically review the studies that have broadly examined QOL outcomes after liver transplantation. The reviewed studies used measures that led to broad assessment of the various domains of QOL. Although the instruments used to measure QOL in these studies are largely validated, there is significant heterogeneity in this literature in terms of the instruments used, leading to difficulties in making generalizable conclusions among the studies. Although limited by internal validity problems, the available data suggest improvement in QOL by liver transplantation. Additionally, a large recent study that used the Liver Transplant Database Quality of Life Questionnaire also reported a subset of patients in whom QOL seemed to worsen after liver transplantation. Knowledge of the factors related to QOL outcome after liver transplantation is important because it might allow development of new interventions that may have an impact on future allocation decisions.
