Patient-reported outcomes and patient-reported outcome measures in liver transplantation: a scoping review

Introduction Generic or condition-specific Patient-reported Outcome Measures (PROMs) are used to measure physical, mental, and social aspects of health to promote patient-centered care. This scoping review aims to identify and summarize generic and condition-specific PRO domains and PROMs that have been assessed and used in liver transplant (LT) candidates and recipients. Methods We searched Medline, Embase, Cochrane Database of Systematic Reviews and Register of Trials, PsychInfo, and CINAHL from inception to 08/26/2020. Included studies addressed a PRO or PROM in LT candidates or recipients. Results After screening, 341 studies yielded 189 unique PRO domains. Mental health domains (depression, anxiety, and guilt) were most frequently assessed, followed by domains of physical and social health. Fifty-one generic and three condition-specific unique PROMs were identified, with only 13% ( n = 45) of studies including condition-specific tools. Discussion The most frequent PROMs were the SF-36, Nottingham Health Profile, Hospital Anxiety and Depression Scale, followed by the Liver Disease Quality of Life (LDQoL). Very few studies used transplant-specific PROMs, which may partly be related to the scarcity of LT-specific instruments. We will use these results in future qualitative research to identify PROs and PROMs to build an electronic PROM toolkit to facilitate patient-centered LT care.
