Assessment of the relative performance of the EQ-5D-3L, ICIQ UI SF and POP-SS using data from the OPAL trial

Conducting economic evaluations alongside randomised controlled trials (RCTs) is an efficient way to collect cost-effectiveness data. Generic preference-based measures, such as EQ-5D, are often used alongside clinical data measures in RCTs. However, in the case of female urinary incontinence (UI), evidence of the relative performance of EQ-5D with condition-specific measures such as the International Consultation on Incontinence Questionnaire Urinary Incontinence Short Form (ICIQ-UI SF), measuring severity of UI, and Pelvic Organ Prolapse Symptom Score (POP-SS), measuring severity of prolapse symptoms, is limited. This study employed secondary analysis of outcome measures data collected during the Optimal Pelvic floor muscle training for Adherence Long-term (OPAL) RCT, which compared biofeedback-mediated pelvic floor muscle training to basic pelvic floor muscle training for women with UI. The relative performance of EQ-5D-3L and ICIQ-UI SF, and EQ-5D-3L and POP-SS was assessed for concurrent validity and known-groups validity. Data for 577 women (mean age 48) were available for EQ-5D-3L/ICIQ-UI SF, and 555 women (mean age 47) for EQ-5D-3L/POP-SS. Overall, EQ-5D-3L exhibited very weak association with the ICIQ-UI SF total score, or any subscale. EQ-5D-3L and POP-SS were found to be weakly correlated. EQ-5D-3L was able to distinguish between groups with known differences in severity of UI and also between types of UI. These findings provide useful information to guide researchers in selecting appropriate outcome measures for use in future clinical trials

Cost consequence analysis of transcutaneous tibial nerve stimulation (TTNS) for urinary incontinence in care home residents alongside a randomised controlled trial

Background: Urinary 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.Methods: A 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 minutes 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. Results: HRQoL 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 hours. 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 minutes 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).Conclusions: Use 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

Pelvic floor muscle training for women with pelvic organ prolapse: the PROPEL realist evaluation

Background Pelvic organ prolapse is estimated to affect 41–50% of women aged > 40 years. A multicentre randomised controlled trial of individualised pelvic floor muscle training found that pelvic floor muscle training was effective in reducing symptoms of prolapse, improved quality of life and showed clear potential to be cost-effective. Provision of pelvic floor muscle training for prolapse has continued to vary across the UK, with limited availability of specialist physiotherapists to deliver it. Objectives This project aimed to study the implementation and outcomes of different models of delivery to increase the service provision of pelvic floor muscle training, and to follow up treatment outcomes for the original trial participants. Design A realist evaluation of pelvic floor muscle training implementation conducted within three full case study sites and two partial case study sites; an observational prospective cohort study comparing patient-reported outcomes pre and post intervention in all five sites; and a long-term follow-up study linking previous trial participants to routine NHS hospital data. Setting The setting for the realist evaluation was pelvic floor muscle training service delivery models in three NHS sites. The setting for the patient-reported outcome measures study was pelvic floor muscle training services in five NHS sites. Methods Realist evaluation qualitative data were collected at four time points in three case study sites to understand the implementation models, uptake, adherence and impact. Interviews involved service managers/leads, consultants, staff delivering pelvic floor muscle training and women receiving pelvic floor muscle training. Main outcomes measures Patient-reported outcomes were collected at baseline and at 6 and 12 months across five sites, including the Pelvic Organ Prolapse Symptom Score, health-related quality of life (measured using the EuroQol-5 Dimensions, five-level version, questionnaire), prolapse severity (measured using the Pelvic Organ Prolapse Quantification System), urinary incontinence (measured using International Consultation on Incontinence Questionnaire – Urinary Incontinence Short Form) and need for further treatment. Results A total of 102 women were recruited to the patient-reported outcome measures cohort study (target, n = 120), and 65 women had matched baseline and 6-month Pelvic Organ Prolapse Symptom Scores. The mean Pelvic Organ Prolapse Symptom Score was 10.18 (standard deviation 5.63) at baseline and 6.98 (standard deviation 5.23) at 6 months, representing a statistically significant and clinically meaningful difference. There was no statistically significant difference between the outcomes obtained from delivery by specialist physiotherapists and the outcomes obtained from delivery by other health-care professionals (mean change in Pelvic Organ Prolapse Symptom Score: –3.95 vs. –2.81, respectively). Services delivered using higher-band physiotherapists only were more costly than services delivered using other staff mixes. The effect of the original pelvic floor muscle training intervention, over a post-intervention period of > 10 years, was a reduction in the odds of any treatment during follow-up (odds ratio 0.61, 95% confidence interval 0.37 to 0.99). The realist evaluation revealed stark differences in implementation. The site with a specialist physiotherapy service resisted change because of perceived threats to the specialist role and concerns about care quality. Pelvic floor muscle training delivery by other health-care staff was easier when there was a lack of any existing specialist service; staff had prior training and interest in pelvic health; staff had support, autonomy, time and resources to deliver pelvic floor muscle training as part of their core role; and surrounding services supported a flow of pelvic floor muscle training referrals. Limitations The number of available matched pre and post outcomes for women and the lack of Pelvic Organ Prolapse Quantification System examinations were limitations of this study. Conclusions It is possible to train different staff to effectively deliver pelvic floor muscle training to women. Women’s self-reported outcomes significantly improved across all service models. Training should be adequately tailored to differential skill mix needs. Future work Future work should include further implementation of pelvic floor muscle training and should include pre- and post-outcome data collection using the Pelvic Organ Prolapse Symptom Score

Foot pain and foot health in an educated population of adults: results from the Glasgow Caledonian University Alumni Foot Health Survey

Abstract Background Foot pain is common amongst the general population and impacts negatively on physical function and quality of life. Associations between personal health characteristics, lifestyle/behaviour factors and foot pain have been studied; however, the role of wider determinants of health on foot pain have received relatively little attention. Objectives of this study are i) to describe foot pain and foot health characteristics in an educated population of adults; ii) to explore associations between moderate-to-severe foot pain and a variety of factors including gender, age, medical conditions/co-morbidity/multi-morbidity, key indicators of general health, foot pathologies, and social determinants of health; and iii) to evaluate associations between moderate-to-severe foot pain and foot function, foot health and health-related quality-of-life. Methods Between February and March 2018, Glasgow Caledonian University Alumni with a working email address were invited to participate in the cross-sectional electronic survey (anonymously) by email via the Glasgow Caledonian University Alumni Office. The survey was constructed using the REDCap secure web online survey application and sought information on presence/absence of moderate-to-severe foot pain, patient characteristics (age, body mass index, socioeconomic status, occupation class, comorbidities, and foot pathologies). Prevalence data were expressed as absolute frequencies and percentages. Multivariate logistic and linear regressions were undertaken to identify associations 1) between independent variables and moderate-to-severe foot pain, and 2) between moderate-to-severe foot pain and foot function, foot health and health-related quality of life. Results Of 50,228 invitations distributed, there were 7707 unique views and 593 valid completions (median age [inter-quartile range] 42 [31–52], 67.3% female) of the survey (7.7% response rate). The sample was comprised predominantly of white Scottish/British (89.4%) working age adults (95%), the majority of whom were overweight or obese (57.9%), and in either full-time or part-time employment (82.5%) as professionals (72.5%). Over two-thirds (68.5%) of the sample were classified in the highest 6 deciles (most affluent) of social deprivation. Moderate-to-severe foot pain affected 236/593 respondents (39.8%). High body mass index, presence of bunions, back pain, rheumatoid arthritis, hip pain and lower occupation class were included in the final multivariate model and all were significantly and independently associated with moderate-to-severe foot pain (p < 0.05), except for rheumatoid arthritis (p = 0.057). Moderate-to-severe foot pain was significantly and independently associated lower foot function, foot health and health-related quality of life scores following adjustment for age, gender and body mass index (p < 0.05). Conclusions Moderate-to-severe foot pain was highly prevalent in a university-educated population and was independently associated with female gender, high body mass index, bunions, back pain, hip pain and lower occupational class. Presence of moderate-to-severe foot pain was associated with worse scores for foot function, foot health and health-related quality-of-life. Education attainment does not appear to be protective against moderate-to-severe foot pain

Long-term effects and costs of pelvic floor muscle training for prolapse: trial follow-up record-linkage study

Introduction: Pelvic organ prolapse affects around 40% of women aged over 50 years. A multicentre parallel group randomised trial (the Pelvic Organ Prolapse PhysiotherapY (POPPY) trial) demonstrated pelvic floor muscle training (PFMT) was effective in reducing prolapse symptoms compared to no treatment. However, insight into the long-term impact of PFMT on health outcomes and health service utilisation is scarce. Methods: This study utilised linkage of Scottish administrative health records to follow-up POPPY trial participants resident in Scotland over 11 years. Mixed effects logistic regression determined the likelihood of receiving further prolapse treatment for those in the PFMT and control group. Analyses were adjusted for age group, prolapse stage, baseline symptom severity and attitude towards surgery. A cost assessment estimated longitudinal costs to the UK National Health Service (in Scotland) of accessing further prolapse treatment for each trial group. Results: 293 women, aged 25 to 79 years, were followed-up. 141 women (48.1%) had received further prolapse treatment: 65 (of 149; 43.6%) in the PFMT group compared with 76 (of 144; 52.8%) in the control group. PFMT was associated with a reduction in the odds of any prolapse treatment during follow-up (AOR 0.61 95% CI 0.37 to 0.99). Total cost of secondary care was 154,544 (GBP) PFMT group and 172,549 (GBP) control group. Conclusions: While PFMT did not lead to significant differences in total costs for further prolapse treatment over a post-intervention period of more than 10 years, it reduced the overall long-term risk of requiring hospital-based treatment for pelvic floor disorders
