Preventing Functional Urinary Incontinence in Hip-Fractured Older Adults Through Patient Education: A Randomized Controlled Trial

Abstract

The purpose of this study was to evaluate whether an educational intervention would reduce the incidence of functional urinary incontinence (UI) in older adults with a fall-related hip fracture. The project was conducted as a multicenter randomized controlled trial (RCT). A total of 109 patients that had been admitted to six hospitals in Castilla-La Mancha (Spain) for acute treatment of hip fracture, previously continent and without cognitive impairment, were enrolled and randomly assigned to the experimental group (EG) or the control group (CG). Intervention (on EG): urinary habit training (Nursing Interventions Classifications taxonomy) was performed during hospital stay (second to fourth postoperative day), with a telephonic reinforcement 10 days after discharge. The CG received routine care. Primary outcome measure: incidence of UI. Follow-up: telephone assessment 3 and 6 months after discharge (blinded evaluation). The incidence of UI at 6 months was 49% (CG) versus 25.5% (EG) (relative risk = 0.52, 95% confidence interval [0.3, 0.9]; number necessary to treat = 4). The mean of UI episodes was 0.54 (EG) versus 1.8 (CG), p = .007. The educational intervention prevents the development of UI and decreases the number of episodes in case of appearance, in a statistically significant way.
