Promoting urinary continence in women after delivery: Randomised controlled trial

Abstract

Objectives: To test the effectiveness of a physiotherapist delivered intervention designed to prevent urinary incontinence among women three months after giving birth. Design: Prospective randomised controlled trial with women randomised to receive the intervention (which entailed training in pelvic floor exercises and incorporated strategies to improve adherence) or usual postpartum care. Setting: Postpartum wards of three tertiary teaching hospitals in the Hunter region, New South Wales, Australia. Participants: Women who had forceps or ventouse deliveries or whose babies had a high birth weight (≥4000 g), or both - 676 (348 in the intervention group and 328 in the usual care group) provided endpoint data at three months. Main outcome measures: Urinary incontinence at three months measured as a dichotomous variable. The severity of incontinence was also measured. Serf report of the frequency of performance of pelvic floor exercises was recorded. Results: At three months after delivery, the prevalence of incontinence in the intervention group was 31.0% (108 women) and in the usual care group 38.4% (125 women); difference 7.4% (95% confidence interval 0.2% to 14.6%, P=0.044). At follow up significantly fewer women with incontinence were classified as severe in the intervention group (10.1%) v (17.0%), difference 7.0%, 1.6% to 11.8%). The proportions of women reporting doing pelvic floor exercises at adequate levels was 84% (80% to 88%) for the intervention group and 58% (52% to 63%) for the usual care group (P=0.001). Conclusions: The intervention promoting urinary continence reduced the prevalence of urinary incontinence after giving birth, particularly its severity, and promoted the performance of pelvic floor exercises at adequate levels; both continence and adherence to the programme were measured at three months after delivery in women who had forceps or ventouse deliveries or babies weighing 4000 g or more.
