RESUMEN
AIMS: To evaluate the long-term effect of the Tät®II app for treatment of urgency (UUI) and mixed urinary incontinence (MUI). METHODS: Long-term follow-up of a randomized controlled trial, including 123 women ≥18 years old with UUI or MUI, without red-flag symptoms, and ≥2 leakages per week. All participants, regardless of group, had received the intervention, a treatment app, at the long-term follow-up. Long-term data were collected through web-based questionnaires 15 months after participants received the intervention. The app included pelvic floor muscle training, bladder training, psychoeducation, lifestyle advice, an exercise log, reminders, reinforcement messages, and tailored advice. The primary outcome was a change in incontinence symptoms (International Consultation on Incontinence Questionnaire [ICIQ]-Urinary Incontinence Short Form [ICIQ-UI SF]), from baseline to follow-up. Other outcomes were urgency symptoms (ICIQ-Overactive Bladder Module (ICIQ-OAB)), quality of life (ICIQ-Lower Urinary Tract Symptoms Quality of Life Module [ICIQ-LUTSqol]), and improvement (Patient's Global Impression of Improvement [PGI-I]). RESULTS: Of the 123 women, 102 (83%) completed the long-term follow-up. The ICIQ-UI SF mean score improved from 11.5 to 7.6 (mean difference 4.0, 95% CI 3.2-4.7). The ICIQ-OAB improved from 6.7 to 5.5 (mean difference 1.3, 95% CI 0.9-1.6) and the ICIQ-LUTSqol improved from 38.0 to 30.9 (mean difference 7.1, 95% CI 5.7-8.5). Of the 102 women, 74 (73%) reported improvement. CONCLUSIONS: Self-management with the Tät®II app for UUI and MUI had a significant effect across all outcome measures also long-term and might serve as an alternative first-line treatment for these conditions.
