Self-management of overactive bladder at home using transcutaneous tibial nerve stimulation: a qualitative study of women’s experiences

ABSTRACT:

Background

Transcutaneous tibial nerve stimulation (TTNS) has been used to treat overactive bladder (OAB), however patient experiences and views of this treatment are lacking. The aim of this study was to explore women’s experiences of OAB and TTNS treatment and the perceived factors influencing participation and adherence.

Methods

Semi-structured, individual interviews conducted as part of a mixed-methods, randomised, feasibility trial of self-managed versus HCP-led TTNS. Interviews were audio recorded and transcribed verbatim. Reflexive thematic analysis was undertaken using Booth et al. (Neurourol Urodynam. 2017;37:528–41) approach.

Results

16 women were interviewed, 8 self-managing TTNS at home and 8 receiving TTNS in twice-weekly hospital clinic appointments. Women self-managing OAB considered TTNS easy to administer, flexible and favourably ‘convenient’, especially when the participant was bound by work and other life commitments. In contrast to OAB symptoms ‘dominating life’, self-managing bladder treatment was empowering and fitted around home life demands. Flexibility and control engendered by self-management, facilitated women’s willingness to participate in TTNS. Women attending a hospital clinic for TTNS enjoyed the social aspects but found the routine appointments constrained their lives. Motivation to continue TTNS in the longer term was dependent on perception of benefit.

Conclusions

This study provides novel insights into women’s experiences of self-managing their OAB using TTNS compared to HCP-led management in the clinical setting. It highlights positive experiences self-managing TTNS at home and a willingness to continue in the longer term, facilitated by ease of use and convenience.

Project description:BackgroundOveractive bladder (OAB) is a problem that increasingly affects adults and the elderly, especially women. It may affect quality of life, ability to participate and overall wellbeing. Transcutaneous tibial nerve stimulation (TTNS) is a form of neuromodulation involving the use of electrical impulses to address urinary symptoms. There are many randomized controlled trials that have shown that TTNS is effective at treating overactive bladder. In recent years, TTNS has gained increasing attention for this condition. But its effect in females remains controversial and evidence is lacking. Therefore, the main purpose of this study will be to systematically evaluate the effect of TTNS on females with OAB in Multiple sclerosis (MS) by conducting a systematic review and meta-analysis, and also to provide a reference for the application of TTNS in OAB.MethodsA systematic review of eligible articles will be conducted using Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines. A comprehensive search of the literature will be conducted in PubMed, Web of Science, The Cochrane Library, Chinese National Knowledge Infrastructure Database (CNKI), Wanfang Data, Weipu Electronics, and other databases. We will include randomized controlled trials about TTNS in females with OAB in MS. Two reviewers will screen titles, abstracts, and full texts independently. We will use a hierarchy of recommended assessment, development, and assessment methods to assess the overall certainty of the evidence and report findings accordingly. Endnote X9 will be used to select the studies and Review Manager V.5.4 (Cochrane Collaboration) will be used to conduct the meta-analysis. The mean difference or standard deviation with 95% confidence interval (CI) will be used in the computation of continuous variables to synthesize data.ResultsThe results will provide evidence for judging whether TTNS is effective in females with OAB and MS.ConclusionThis study will provide reliable evidence for the effect of TTNS in female patients with OAB and MS.Trial registrationSystematic review registration: PROSPERO CRD42021256861.

Project description:BackgroundNeurogenic lower urinary tract dysfunction is an abnormality in the presence of underlying neurologic disease. A recent systematic review and meta-analysis demonstrated that storage phase symptoms are the predominant symptoms among people with multiple sclerosis (PwMS). Transcutaneous tibial nerve stimulation (TTNS) is a non-invasive treatment for bladder storage symptoms; however, the potential efficacy of stimulation among PwMS is based on a small number of studies with the absence of high-quality evidence. The aim of this study was to evaluate the feasibility, acceptability, and safety of TTNS in PwMS using an affordable transcutaneous electrical nerve stimulation (TENS) unit.MethodsA total of 23 participants with MS enrolled in the study. The primary outcomes included recruitment/retention rate, completion of the outcomes and the intervention, adherence to the protocol, adverse events, and acceptability of the intervention. The primary outcomes were assessed using diaries and a satisfaction questionnaire. The secondary outcomes included changes in urinary symptoms and quality of life assessed using a set of validated outcome measures including a 3-day bladder diary, PPIUS, ICIQ-OAB, and KHQ at baseline and post-intervention.ResultsTwenty participants completed the study. Three participants (13.04%) withdrew. All 20 participants completed the 6-week intervention and all the outcome measures (100%), with no reported adverse events. Participants were satisfied and found the unit acceptable. Three-day bladder diary showed changes in urinary frequency from a daily median of 10 times to 8 times and daily median urgency changed from 6 times at baseline to 2 times post-intervention. PPIUS showed changes in daily median sever urgency from 3 points (IQR=4) to 1 point (IQR=1) post-intervention. ICIQ-OAB total scores changed from 8 points (IQR=2.25) to 4 points (IQR=2.5) post-intervention. Median and mean scores of KHQ showed a clinical meaningful change of QoL in part-two and part-three of the questionnaire.ConclusionsTTNS is feasible, safe, and acceptable for PwMS. Changes of urinary symptoms scores and QoL post-intervention suggested improvements. Future implications need to consider the treatment protocol including frequency of treatment sessions, duration of treatment, and the electrical stimulation parameters as well as the outcome measures followed in the current study for the implementation of the future pilot RCT.Trial registrationClinicalTrials.gov NCT04528784 .

Project description:BackgroundUrinary incontinence (UI) is prevalent in more than half of residents of nursing and residential care homes and can have a detrimental impact on dignity and quality of life. Care homes predominantly use absorbent pads to contain UI rather than actively treat the condition. Transcutaneous tibial nerve stimulation (TTNS) is a non-invasive, safe, low-cost intervention with demonstrated effectiveness for reducing UI in adults. We examined the costs and consequences of delivering TTNS to care home residents in comparison to sham (inactive) electrical stimulation.MethodsA cost consequence analysis approach was used to assemble and present the resource use and outcome data for the ELECTRIC trial which randomised 406 residents with UI from 37 care homes in the United Kingdom to receive 12 sessions of 30 min of either TTNS or sham (inactive) TTNS. TTNS was administered by care home staff over 6 weeks. Health state utility was measured using DEMQOL-U and DEMQOL-PROXY-U at baseline, 6 weeks and 18 weeks follow-up. Staff completed a resource use questionnaire at baseline, 6 weeks and 18 weeks follow-up, which also assessed use of absorbent pads.ResultsHRQoL did not change significantly in either randomised group. Delivery of TTNS was estimated to cost £81.20 per participant, plus training and support costs of £121.03 per staff member. 85% of participants needed toilet assistance as routine, on average requiring one or two staff members to be involved 4 or 5 times in each 24 h. Daily use of mobility aids and other assistive devices to use the toilet were reported. The value of staff time to assist residents to use the toilet (assuming an average of 5 min per resident per visit) was estimated as £19.17 (SD 13.22) for TTNS and £17.30 (SD 13.33) for sham (per resident in a 24-hour period).ConclusionsUse of TTNS to treat UI in care home residents did not lead to changes in resource use, particularly any reduction in the use of absorbent pads and no cost benefits for TTNS were shown. Managing continence in care homes is labour intensive, requiring both high levels of staff time and use of equipment aids.Trial registrationISRCTN98415244, registered 25/04/2018.

Project description:BackgroundTranscutaneous tibial nerve stimulation (TTNS) and percutaneous tibial nerve stimulation (PTNS) are effective and safe therapies for overactive bladder (OAB) syndrome in adults. However, few randomized sham-controlled trials have been conducted in a pediatric population. To our knowledge, both therapies never have been compared in children.AimThe aim of the complete study is twofold: (1) to assess the efficacy of TTNS therapy on bladder symptoms after 12 weeks of treatment in a pediatric population with idiopathic overactive bladder syndrome (iOAB) and/or nocturnal enuresis (part I) and (2) to assess the effect of TTNS compared to PTNS (part II). In this article, we aim to present the protocol of the first part of the TaPaS trial (TTNS, PTNS, sham therapy).MethodsPart I of the TaPaS trial is set up as a single-center randomized-controlled trial. Children, aged from 5 to 12 years with iOAB and/or nocturnal enuresis, are assigned to two groups by computer-generated randomization: TTNS therapy (intervention) and sham therapy (control). The primary outcome is the percentage difference in average voided volume (AVV) between baseline and after 12 weeks of treatment. Secondary endpoints are the percentage difference in supervoid volumes, number of urinary incontinence episodes/24 h and in voiding frequency, the difference in parent reported outcomes between baseline and after 12 weeks of treatment, and the duration of clinical response.DiscussionWe hypothesize that TTNS is a non-inferior treatment for iOAB in children compared to PTNS therapy. Since literature is inconclusive about the efficacy of TTNS in a pediatric population, a sham-controlled RCT on TTNS will be conducted (part I). A protocol for a prospective randomized sham-controlled trial has been developed. Enrolment has started in November 2018. Study completion of part I is expected by August 2021.Trial registrationClinicalTrials.gov NCT04256876 . Retrospectively registered on February 5, 2020.

Project description:Background: Neurogenic lower urinary tract dysfunction (NLUTD) is common among people with multiple sclerosis (MS) with a pooled prevalence of 68.41% using self-report measures and 63.95% using urodynamic studies. Transcutaneous tibial nerve stimulation (TTNS) is a non-invasive option to manage bladder storage symptoms; however, the potential efficacy of TTNS among people with MS is based on a small number of studies with the absence of high-quality evidence relating to efficacy, and lack of clarity of the optimal electrical stimulation parameters and frequency, duration and number of treatment sessions. This study aims to assess whether TTNS is feasible and acceptable as a treatment for bladder storage symptoms in people with MS. Methods: We will use a single-arm experimental study to explore the feasibility and acceptability of TTNS in the treatment of bladder storage symptoms in MS. The CONSORT extension for pilot and feasibility studies will be followed to standardise the conduct and reporting of the study. The recruitment plan is twofold: 1) Open recruitment for people with MS through MS Ireland's communication channels; 2) recruitment from a convenience sample of people with MS who have previously participated in a qualitative interview study of urinary symptoms. We will assess recruitment/retention rates, the urinary symptoms changes and the effect on quality of life pre and post intervention using ICIQ-OAB, 3-day bladder diary, King's Health Questionnaire and collect self-reported data on adherence and adverse events. Acceptability of using TTNS will be evaluated at the end of intervention. This study has been reviewed and approved by the Education and Health Science's Faculty Research Ethics Committee, University of Limerick [2020_06_07_EHS]. Conclusion: It is anticipated that assessing the feasibility and acceptability of TTNS for storage bladder symptoms in MS will inform the development of a definitive randomised trial.
