Quality of Life Measurement in Adults with Multiple Long-Term Conditions

A patient with three or four chronic conditions fills in a quality-of-life questionnaire, but the questions were designed for someone with only one disease. This scoping review systematically maps the existing literature on quality-of-life Patient Reported Outcome Measures (PROMs) for adults with multiple long-term conditions (MLTCs). The problem is that current PROMs were largely developed for single diseases, so they may miss the full picture of what matters to someone managing several conditions at once—such as how symptoms interact, how treatments conflict, or how daily life is affected in ways no single-disease measure captures. The review identifies which components of quality of life existing measures cover, their limitations, and whether patients’ own lived experiences were included in developing or evaluating those measures. If this work succeeds, it will highlight specific gaps in current evidence and point researchers toward better, more personalised ways to measure quality of life in this growing patient group. That could eventually change how clinicians assess treatment success and how health services allocate resources, but the immediate output is a clearer map of what we still need to learn.
