Impact of innovative pelvic floor muscle training on quality-adjusted life years (QALYs) in women with stress urinary incontinence treated by duloxetine

Abstract

ObjectivesThe aim of this study was to measure the impact of innovative pelvic floor muscle training (iPFMT) on Quality-Adjusted Life Years (QALYs) in women with stress urinary incontinence (SUI) treated by duloxetine. Study designThis analysis is part of the DULOXING study conducted between February 2019 and 2020. The control group received oral duloxetine treatment (40 mg BID), and the experimental group received oral duloxetine treatment (40 mg BID) and iPFMT with lumbopelvic stabilization. SUI was analysed at baseline and in the final period according to the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI SF). The QALYs gained were calculated by multiplying life expectancy (LE) by a weighting factor (QALYs = LE * WF). ResultsThe study included 158 women, of whom 129 were fully analysed (81.6%). The mean life expectancy was 26.3 ± 11.8 years for the control group and 29.0 ± 11.7 years for the experimental group. The mean baseline ICIQ-UI SF scores were 15.2 ± 1.7 vs 15.1 ± 1.5, and the final ICIQ-UI SF scores were 9.8 ± 4.2 vs 8.3 ± 3.8, in the control vs the experimental group, respectively (p < 0.05). The mean baseline WF was 0.27 ± 0.08 vs 0.28 ± 0.07, and the final WF was 0.53 ± 0.20 vs 0.60 ± 0.18, in the control vs the experimental group, respectively (p < 0.05). Before treatment, the number of QALYs during life expectancy in the control vs the experimental group was 7.53 ± 4.24 vs 8.30 ± 4.01. The number of QALYs during life expectancy in control vs the experimental group increased following treatment: 15.03 ± 7.63 vs 17.90 ± 7.86 (p < 0.05). ConclusionsCombination treatment with duloxetine and iPFMT statistically significantly increased the number of QALYs and reduced the degree of urinary incontinence in women with stress urinary incontinence.
