With improved survival rates after pediatric liver transplantation (LT), attention is targeting improving the health-related quality of life (HRQOL) as an outcome metric. We conducted a systematic review of the literature to examine HRQOL after pediatric LT, focusing on assessment tools and factors associated with HRQOL. A literature search was conducted through PubMed, Web of Science, Ovid, and Google Scholar for all studies matching the eligibility criteria between January 2004 and September 2016. Titles and abstracts were screened independently by 2 authors and consensus for included studies was achieved through discussion. A total of 25 (2 longitudinal, 23 cross-sectional) studies were reviewed. HRQOL in pediatric LT recipients is lower than healthy controls, but it is comparable to children with chronic diseases or other pediatric solid organ transplant recipients. Domain scores were lowest in school functioning on the Pediatric Quality of Life Inventory (PedsQL) Generic Core Scale 4.0 and general health perception on the Child Health Questionnaire, the 2 most commonly used generic HRQOL instruments. Identified predictors of poor HRQOL include sleep disturbances, medication adherence, and older age at transplantation. Two recently validated disease-specific HRQOL tools, Pediatric Liver Transplant Quality of Life tool and the Pediatric Quality of Life Inventory 3.0 Transplant Module, have enabled enhanced representation of patient HRQOL, when used in conjugation with generic tools. Heterogeneity in study design and instruments prevented a quantitative, meta-analysis of the data. In conclusion, continued optimization of durable outcomes for this population mandates prioritization of research focusing on the gap of targeted intervention studies aimed at specific HRQOL subdomains and longitudinal studies to predict the trajectory of HRQOL over time.
