Abstract
BACKGROUND: Hospital falls remain common and approximately 30% of falls in hospital result in injury. The aims of the study were the following: (i) to identify the association between fall interventions present at the time of the injurious fall and injurious faller characteristics and (ii) to identify the association between fall preventive interventions present at the time of the injurious fall and the injurious fall circumstances. METHODS: Secondary data analysis of deidentified case series of injurious falls across 24 acute medical/surgical units in the United States. Variables of interest were falls prevention interventions (physical therapy, bed alarm, physical restraint, room change, or a sitter) in place at the time of fall. Data were analyzed using logistic regression and hazard ratios. RESULTS: There were 1,033 patients with an injurious fall, occurrence peaked between Day 1 and Day 4, with 46.8% of injurious falls having occurred by Day 3 of admission. Injurious fallers with a recorded mental state change 24 hours prior to the fall were more likely to have a bed alarm provided (adjusted odds ratio [OR] 2.56, 95% confidence interval [CI] 1.61, 4.08) and receive a physical restraint as fall prevention interventions (adjusted OR 6.36, 95% CI 4.35, 9.30). Injurious fallers restrained fell later (stay Day 6) than those without a restraint (stay Day 4) (p = .007) and had significantly longer lengths of stay (13 days vs 9 days). CONCLUSIONS: On medical/surgical units, injurious falls occur early following admission suggesting interventions should be commenced immediately. Injurious fallers who had a physical restraint as an intervention had longer lengths of stay.
