Effects of Nursing Interventions for Fall Prevention in Hospitalized Patients: A Meta-analysis

ABSTRACT

PURPOSE: The purpose of this study was to identify which nursing interventions are the most effective in fall prevention for hospitalized patients. METHODS: From 3,675 papers searched, 34 were selected for inclusion in the meta-analysis. Number of fallers, falls, falls per 1,000 hospital-days, and injurious falls, fall protection activity, knowledge related to falls, and self-efficacy about falls were evaluated as outcome variables. Data were analyzed using the Comprehensive Meta Analysis (CMA) 2.2 Version program and the effect sizes were shown as the Odd Ratio (OR) and Hedges's g. RESULTS: Overall effect size of nursing interventions for fall prevention was OR=0.64 (95% CI 0.57~0.73, p <.05) and Hedges's g= - 0.24. The effect sizes (OR) of each intervention ranged from 0.34 to 0.93, and the most effective nursing intervention was the education & environment intervention (OR=0.34, 95% CI 0.28~0.42, p <.001), followed by education intervention (OR=0.57, 95% CI 0.50~0.67, p =.001). Subgroup analyses showed that multifaceted interventions (OR=0.76, 95% CI 0.73~0.79, p <.001) were more effective than unifactorial interventions, and that activities for prevention of falls (OR=0.08, 95% CI 0.05~0.15, p <.001) showed the largest effect size among outcome variables. CONCLUSION: Falls in hospitalized patients can be effectively prevented using the nursing interventions identified in this study. These findings provide scientific evidence for developing and using effective nursing interventions to improve the safety of hospitalized patients.
