Patient pathway in a tertiary referral pelvic floor unit: Telephone triage assessment clinic.

BACKGROUND: To meet the increasing demands for colorectal pelvic floor services, a dedicated telephone triage assessment clinic (TTAC) was set up to establish a more efficient pathway, and reduce waiting times and patient's visits to the hospital. The primary aim of this study was to review TTAC in patients suffering from pelvic floor dysfunction and assess its feasibility. Secondary aims include measurement of waiting times for TTAC, main presenting complaints, and main treatment outcomes, including the need for review by a consultant surgeon. METHODS: Review of data collected retrospectively in a single tertiary referral center collected from an institutional database. KEY RESULTS: Between January 2016 and October 2017, 1192 patients referred to our pelvic floor unit were suitable for TTAC. Of these, 694 patients had complete records. There were 66 without follow-up after the initial TTAC, leaving 628 patients for analysis. In all, 86% were females and 14% were males, with a mean age of 52 years (range: 18-89). The median waiting time for TTAC was 31 days (range: 0-184). The main presenting complaint during the TTAC was obstructive defecation in 69.4%, fecal incontinence in 28.5%, and rectal prolapse in 2.1%. In our study, 611 patients had conservative management (97.3%), with a median of three sessions per patient (range: 1-16), while 82 patients (13.1%) needed a surgical intervention. Only 223 patients (35.5%) were reviewed by a consultant at some stage during the study period. CONCLUSIONS AND INFERENCES: To optimize resources, an adequate triage system allowed us to streamline the pathway for each individual patient with pelvic floor dysfunction according to their symptoms and/or test results with the aim of reducing waiting times and expediting treatment.

Cost Effectiveness of Sacral Neuromodulation and OnabotulinumtoxinA in Managing Refractory Idiopathic Overactive Bladder.

Little information from clinical and modelled studies are available on cost effectiveness of OnabotulinumtoxinA and SNM for the treatment of idiopathic overactive bladder. We aimed to summarize the evidence in this regard from different healthcare systems. Seven studies from 5 countries were reviewed. Some modelled studies with a 10-year time frame showed that sacral neuromodulation became dominant long-term; others suggested OnabotulinumtoxinA was more cost effective at <5 years. There was considerable heterogeneity in the base case/sensitivity analysis and statistical modelling among the studies. Clinical studies with longer term follow-up will help determine cost effectiveness more accurately.

Assessment of treatment-seeking behavior and healthcare utilization in an international cohort of subjects with overactive bladder.

UNLABELLED: Abstract Objective: To assess the association between incontinence severity, treatment-seeking behavior, and healthcare resource utilization (HRU) among participants with overactive bladder (OAB) in eight countries. RESEARCH DESIGN AND METHODS: A cross-sectional online survey of subjects ≥18 years old in Australia, Europe, and North America, who had a past OAB diagnosis and/or experienced ≥1 urinary incontinence (UI) episode in the preceding 12 months, were eligible to participate. Subjects contacted for the survey were primarily from a voluntary medication monitoring registry, MediGuard. Predominantly stress incontinence subjects were excluded. Incontinence severity was assessed by the number of UI episodes over 3 days and grouped as 0 ('dry'), 1-2, 3-4, and ≥5 UI episodes/day. Subject demographics, employment status, comorbidities, treatment-seeking behavior (past OAB diagnosis; spoken to healthcare provider [HCP]), and HRU (diagnostic tests; HCP visits in 6 months before screening) were analyzed by incontinence severity. RESULTS: Overall, 1341 subjects with OAB (mean age 54.5 years; 70.7% female) were surveyed; 20.2%, 47.7%, 18.8%, and 13.3% of subjects reported 0, 1-2, 3-4, and ≥5 UI episodes/day, respectively. Employment status and comorbidities were significantly (p < 0.05) associated with incontinence severity. The two measures of treatment-seeking behavior were significantly (p < 0.05) associated with incontinence severity groups; the proportion of subjects with a past diagnosis of OAB were 35.8%, 44.8%, 52.4%, and 64.0% in the 0, 1-2, 3-4, and ≥5 UI episodes/day groups, respectively; and 59.0%, 63.6%, 65.9%, and 78.1% of subjects in the respective UI severity groups talked to a HCP about their OAB symptoms. Multivariate linear regression analyses showed a positive and consistent association between incontinence severity and HRU; subjects reported a mean of 2.7, 4.1, 4.4, and 7.7 diagnostic tests overall (p < 0.001), and a mean of 1.4, 2.2, 2.7, and 4.0 HCP visits in the 0, 1-2, 3-4, and ≥5 UI episodes/day groups, respectively (p < 0.001). A potential limitation of the study is the cross-sectional survey methodology which limits the ability to draw causal inferences from the results. Additionally, since this is a web-based survey it is possible respondents who have access to/are familiar with technology were more likely to be enrolled. CONCLUSIONS: Incontinence severity was positively associated with both treatment-seeking behavior and HRU among subjects with OAB.

Validation of the bladder control self-assessment questionnaire (B-SAQ) in men.

OBJECTIVE: To validate the Bladder Control Self-Assessment Questionnaire (B-SAQ), a short screener to assess lower urinary tract symptoms (LUTS) and overactive bladder (OAB) in men. PATIENTS AND METHODS: This was a prospective, single-centre study including 211 patients in a urology outpatient setting. All patients completed the B-SAQ and Kings Health Questionnaire (KHQ) before consultation, and the consulting urologist made an independent assessment of LUTS and the need for treatment. The psychometric properties of the B-SAQ were analysed. RESULTS: A total of 98% of respondents completed all items correctly in <5 min. The mean B-SAQ scores were 12 and 3.3, respectively for cases (n = 101) and controls (n = 108) (P < 0.001). Good correlation was evident between the B-SAQ and the KHQ. The agreement percentages between the individual B-SAQ items and the KHQ symptom severity scale were 86, 85, 84 and 79% for frequency, urgency, nocturia and urinary incontinence, respectively. Using a B-SAQ symptom score threshold of ≥4 alone had sensitivity, specificity and positive predictive values for detecting LUTS of 75, 86 and 84%, respectively, with an area under the curve of 0.88; however, in combination with a bother score threshold of ≥1 these values changed to 92, 46 and 86%, respectively. CONCLUSIONS: The B-SAQ is an easy and quick valid case-finding tool for LUTS/OAB in men, but appears to be less specific in men than in women. The B-SAQ has the potential to raise awareness of LUTS. Further validation in a community setting is required.

Assessment of urodynamic and detrusor contractility variables in patients with overactive bladder syndrome treated with botulinum toxin-A: is incomplete bladder emptying predictable?

OBJECTIVE: To assess whether incomplete bladder emptying and the need for clean intermittent self-catheterization (CISC) is predictable, by analysing urodynamic and detrusor contractility variables in patients treated with botulinum toxin-A (BTX-A) for refractory idiopathic detrusor overactivity (IDO). PATIENTS AND METHODS: Sixty-seven patients (mean age 50.3) with IDO, from two centres, had bladder injections of 200 U BTX-A. Patients with difficulty in emptying their bladder and/or persistent overactive bladder symptoms, with postvoid residual volumes (PVR) of >150 mL after treatment were started on CISC. Urodynamics were conducted at baseline, 4 and 12-16 weeks after injection with BTX-A. Detrusor contractility was assessed using the projected isovolumetric pressure (PIP1) in women and bladder contractility index (BCI) in men. RESULTS: There were improvements in the mean maximum cystometric capacity, bladder compliance and maximum detrusor pressures during filling cystometry after BTX-A injections. The PVR was significantly increased at 4 but not at 12 weeks. Nineteen patients required CISC and when compared with those not needing CISC their pretreatment maximum flow rate (15 vs 22 mL/s, P = 0.003), PIP1 (43 vs 58, P = 0.02) and BCI (113 vs 180, P = 0.001) were lower. Receiver operator characteristic curve analysis suggested that a PIP1 of < or =50 in women (sensitivity 0.83; specificity 0.70; area under the curve 0.822) and BCI < or =120 (sensitivity 0.7; specificity 0.79; area 0.879) might predict the need for CISC. CONCLUSION: The maximum flow rate, PIP1 and BCI were significantly lower in patients who required CISC after BTX-A treatment than in those who did not. A PIP1 of < or =50 in women and a BCI of < or =120 might be predictive of a need for CISC in this setting, and might help when counselling patients.

Urodynamic assessment of poor responders after botulinum toxin-A treatment for overactive bladder.

OBJECTIVES: Botulinum toxin-A (BTX-A) is effective in treating overactive bladder (OAB) refractory to anticholinergics. Most patients have improvements in symptoms, urodynamic parameters, and quality of life, and a poor response is uncommon. The aim of this study was to determine whether poor responders could be predicted from preoperative urodynamic parameters. METHODS: Data were collected prospectively from 33 OAB patients with idiopathic detrusor overactivity. All patients underwent intradetrusor injections of 200 U BTX-A. Response to treatment was assessed by patient perception, OAB symptoms, and quality of life data. Urodynamics were conducted at baseline and 4, 12, and 24 weeks postinjection. We performed statistical analysis using the Wilcoxon matched pairs, Mann-Whitney, two-sample, and paired t-tests. Receiver operator characteristic (ROC) curves were plotted for relevant parameters. RESULTS: Five patients had a poor response to treatment. Significant increases in maximum cystometric capacity (MCC), reflex detrusor volume (RDV), and bladder compliance with decreases in maximum detrusor pressures (MDP) on filling were observed in the responders over 24 weeks. Minimal urodynamic benefit was observed in the poor responders group over the same period. When comparing the two groups, baseline MDP in poor responders was 138.0 +/- 30.7 compared with 74.4 +/- 32.6 in the responders (P = 0.0028). ROC analysis suggested that a pretreatment MDP greater than 110 may have predictive value (AUC, 0.946; sensitivity, 0.86; specificity, 1.0) for a poor response to treatment. CONCLUSIONS: Very high MDP greater than 110 may predict a poor response to treatment with 200 U of BTX-A. Higher doses may be necessary in these patients.
