663 BEHAVIOUR CHANGE INTERVENTIONS TO INCREASE PHYSICAL ACTIVITY IN HOSPITALISED PATIENTS: A SYSTEMATIC REVIEW AND META-ANALYSIS

Abstract

Abstract Introduction Low physical activity levels are a major problem for people in hospital and are associated with adverse outcomes. This systematic review, meta-analysis and meta-regression aimed to determine the effect of behaviour change interventions on physical activity levels in hospitalised patients. Methods: Randomised controlled trials of behaviour change interventions to increase physical activity in hospitalised patients were searched from MEDLINE, EMBASE, PsychINFO, CINAHL, Cochrane Register of Controlled Trials and PEDr, supplemented by citation tracking. After application of selection criteria and data extraction, data were synthesised with random effects meta-analyses and pre-specified subgroup and meta-regression analyses. The primary outcome was Objectively measured physical activity. Secondary outcomes were patient-related outcomes (e.g. mobility), hospital-level outcomes (e.g. length of stay), adverse events and patient satisfaction. Results Eighteen randomised controlled trials (n = 2,197 participants) of behaviour change interventions were included and were associated with increased physical activity levels (SMD 0.36, 95% CI 0.15 to 0.57). Findings in relation to mobility and length of stay were inconclusive. Adverse events and patient satisfaction were poorly reported. Meta-regression found that the behaviour change technique of goal setting was independently associated with increased physical activity (SMD 0.35, 95% CI 0.11 to 0.60). Conclusion Targeted behaviour change interventions are associated with small to moderate increases in physical activity in hospitalised patients. Goal setting was the behaviour change technique that worked best in increasing physical activity.
