Insights Into Health-Related Quality of Life of Kidney Transplant Recipients: A Narrative Review of Associated Factors.

Life expectancy and graft survival continue to improve after transplantation. However, improved posttransplant clinical outcomes do not necessarily translate into improved health-related quality of life (HRQoL). Therefore, there is an increased focus on HRQoL in kidney transplant recipients (KTRs). The HRQoL of KTRs is worse than that of the general population, but interventions that improve HRQoL in KTRs are scarce, and health care professionals in nephrology care do not routinely address HRQoL. To improve HRQoL, it is essential to understand which factors play a role in HRQoL and to pinpoint areas for intervention. This narrative review maps the concept of HRQoL within the KTR population and provides a comprehensive overview of factors associated with posttransplant HRQoL. The results are structured using an easy-to-understand conceptual model of HRQoL, which is instrumental for understanding how HRQoL is constituted of many clinical and nonclinical factors. We conclude that symptom burden among KTRs is high, which is likely a key driver of the limited HRQoL in this population. Moreover, myriad other clinical and nonclinical factors are associated with HRQoL, but the majority of the evidence is observational.
