Behavioral therapy versus drug therapy in individuals with idiopathic overactive bladder: A systematic review and meta-analysis

Pilot Study of a Digital Behavioral Therapy for Overactive Bladder in Women

IMPORTANCE

The burden and high prevalence of overactive bladder (OAB) underline the urgent need for effective treatment. This study provides an initial look at an alternative approach to behavioral therapy for overactive bladder (OAB) that is delivered as an app on a smartphone.

OBJECTIVE

This study aimed to investigate feasibility, acceptability, and preliminary efficacy of a digital therapeutic for OAB.

STUDY DESIGN

This was a multicentered prospective pilot study. We used a convenience sample (N = 30) from waiting lists of women referred for incontinence, excluding urinary tract infections, urinary retention, bladder pain syndrome, pelvic cancer, current pregnancy, kidney disease, dementia, stroke, and prior neuromodulation. The intervention, a smartphone app, provided an 8-week program with weekly modules combining evidence-based knowledge videos and skill-building exercises that incorporated behavioral therapy, cognitive behavioral therapy, pelvic muscle training, and general health information. Combined scores on the International Consultation on Incontinence Questionnaire was the primary outcome measure. Secondary outcomes included improvement in quality of life, based on International Consultation on Incontinence Questionnaire, a 72-hour urinary diary, and Patient Global Impression of Improvement. We evaluated usability with the Mobile Application Rating Scale. Statistical tests included Shapiro-Wilk tests and paired-sample t tests.

RESULTS

Overall, 100% of participants reported a reduction in their OAB symptoms and 82% reported an improvement in quality of life. There was a significant improvement in diary parameters, including frequency (10.19-6.71 a day: SD, 1.25; P = 0.017) and incontinence (10-3.57: SD, 4.58). Participants rated the app highly on functionality, and 70% would recommend it. Patient Global Impression of Improvement improved for 72% of participants.

CONCLUSIONS

This study supports the application of a digital platform to over-come the real-world barriers for first-line treatment for OAB and offers information to inform further evaluation of the safety and efficacy of the NUIG OAB App.

Efficacy of non‐pharmacological interventions in females with overactive bladder: A systematic review and network meta‐analysis

AIMS AND OBJECTIVES

To compare and rank the effectiveness of non-pharmacological interventions for symptoms of Overactive Bladder (OAB) in network meta-analysis.

BACKGROUND

Overactive Bladder affects many patients, which often generates bothersome symptoms and debilitates the quality of life. Non-pharmacological therapies have been widely used in OAB. However, due to insufficient evidence, it remains unclear which strategies are most suitable for OAB.

METHODS

We integrated randomised controlled trials (RCTs), which were searched up to 1 January 2021, from 8 databases (PubMed, Embase, Cochrane library, Web of Science, China National Knowledge Infrastructure, Wanfang Database, VIP Database, and China Biology Medicine disc). Studies that met the eligible criteria were assessed the risk of bias. Then, network meta-analyses were conducted by STATA, R, and OpenBUGS. The review followed PRISMA statement.

RESULTS

A total of 24 studies comprising 2347 patients with OAB were included in this review, most of which were low to moderate risk of bias. The results of network meta-analysis implied that electric stimulation (ES) was the most effective intervention to reduce voided frequency and nocturia frequency of OAB.

CONCLUSIONS

Electric stimulation ranked the best in the management of OAB, and future studies should pay more attention to ES.

Efficacy of non-pharmacological interventions in patients with overactive bladder: A protocol for systematic review and network meta-analysis

Background

Some meta‐analyses have proved the superiority of non‐pharmacological interventions in overactive bladder (OAB), but the best choice is still controversial.

Aim

To assess the most effective interventions in female with OAB.

Methods

Studies for relevant randomized controlled trials which compare different kinds of non‐pharmacological interventions in females with OAB will be retrieved from 8 databases including PubMed, Cochrane Library, Web of Science, Embase, China National Knowledge Infrastructure, Wanfang Database, VIP Database and China Biology Medicine disc, from inception to 1 January 2021. After screening titles and abstracts, detailed data including participates, interventions and outcomes will be extracted according to the eligible criteria. Then, Cochrane risk‐of‐bias tool will be used to assess the quality of the literature. The pairwise meta‐analysis will be conducted by STATA. Network meta‐analysis will be performed to compare and rank the effects of different non‐pharmacological interventions, in terms of alleviation of symptoms, by OpenBUGS, R and STATA.

Results

This network meta‐analysis will present the best available evidence about non‐pharmacological interventions for OAB to both relieve symptoms and improve life quality.
