Abstract
IMPORTANCE: International guidelines recommend the integration of multidisciplinary rehabilitation into palliative care services but its impact on quality of life across disease types is not well understood. OBJECTIVE: To determine the effect of multidisciplinary palliative rehabilitation on quality of life and healthcare service outcomes for adults with an advanced, life-limiting illness. DATA SOURCES: Electronic databases CINAHL, EMBASE, MEDLINE and PEDro were searched from the earliest records to February 2024. STUDY SELECTION: Randomised controlled trials examining the effect of multidisciplinary palliative rehabilitation in adults with an advanced, life-limiting illness and reported quality of life were eligible. DATA EXTRACTION AND SYNTHESIS: Study characteristics, quality of life and health service usage data were extracted, and the methodological quality was assessed using PEDro. Meta-analyses using random effects were completed, and Grades of Recommendation, Assessment, Development and Evaluation criteria were applied. MAIN OUTCOMES: Quality of life and healthcare service outcomes. RESULTS: 27 randomised controlled trials (n=3571) were included. Palliative rehabilitation was associated with small improvements in quality of life (standardised mean difference (SMD) 0.40, 95% CI 0.23 to 0.56). These effects were significant across disease types: cancer (SMD 0.22, 95% CI 0.03 to 0.41), heart failure (SMD 0.37, 95% CI 0.61 to 0.05) and non-malignant respiratory diagnoses (SMD 0.77, 95% CI 0.29 to 1.24). Meta-analysis found low-certainty evidence, palliative rehabilitation reduced the length of stay by 1.84 readmission days. CONCLUSIONS AND RELEVANCE: Multidisciplinary palliative rehabilitation improves quality of life for adults with an advanced, life-limiting illness and can reduce time spent in hospital without costing more than usual care. Palliative rehabilitation should be incorporated into standard palliative care. PROSPERO REGISTRATION NUMBER: CRD42022372951.
