Pelvic Floor Disorders Among Minority Women: Differences in Prevalence, Severity and Health-Related Social Needs.

OBJECTIVE: To characterize prevalence and severity of pelvic floor disorders (PFDs) in various health care settings and to examine unmet health-related social needs (HRSN) among minority women. MATERIALS AND METHODS: Minority women with PFDs were recruited from our academic urogynecology clinic, a general urology clinic at our institution's safety net hospital, and a community outreach mobile clinic. Questions from the Urinary Distress Index-6, Pelvic Organ Prolapse Distress Inventory-6, and Female Genitourinary Pain Index were used to identify patients with stress urinary incontinence, overactive bladder (OAB), and chronic pelvic pain syndrome (CPPS). RESULTS: Sixty-one (46.6%) women identified as Hispanic, 53 (40.4%) as Black, and 17 (12.9%) as Other. Overall, self-reported PFDs included stress urinary incontinence in 45%, OAB in 74.8%, and CPPS in 24.4% of women. Hispanic women were more likely to report OAB symptoms, compared to Black women (odds ratio (OR) 3.4 [1.2-10.2], P = .03) or Other women (OR = 5.1 [1.3-20.4], P = .02). Participants held a median of 5 unmet HRSN. Minority women facing issues with family and community support, transportation, and utilities were more likely to report CPPS symptoms, compared to those without psychosocial issues (support OR: 4.8 [1.7-13.7], P = .002; transportation OR: 2.0 [1.0-8.2], P = .05; utility OR: 7.0 [1.9-28.1], P = .005). CONCLUSION: Minority women with PFDs may have several unmet HRSNs which impact their ability to receive appropriate medical care. Our findings may assist in the development of effective strategies to improve health care outcomes for women dealing with PFDs.

Mirabegron and antimuscarinic use in frail overactive bladder patients in the United States Medicare population.

INTRODUCTION: Overactive bladder (OAB) and frailty are independently associated with patient burden. However, economic burden and treatment-taking behavior have not been well characterized among frail patients with OAB, which, given the varying safety and tolerability profiles of available treatments, is crucial. OBJECTIVES: To assess costs, health care resource utilization, treatment-taking behavior (persistence and adherence) to OAB medication in older, frail OAB patients. METHODS: This was a retrospective cohort study using international business machines MarketScan Medicare Supplemental claims data. Eligible frail patients (per Claims-based Frailty Index score) initiating mirabegron were 1:2 propensity score matched (based on age, sex, and other characteristics) with those initiating antimuscarinics and were followed up to 1 year. All-cause, per-person, per-month costs, health care encounters, persistence (median days to discontinuation assessed using Kaplan-Meier methods) and adherence (≥80% of proportion of days covered at Day 365) were compared. RESULTS: From 2527 patients with incident mirabegron (21%) or antimuscarinic (79%) dispensations, 516 incident mirabegron users (median age: 82 years, 64% female) were matched to 1032 incident antimuscarinic users (median age: 81 years, 62% female). Median cost was higher in mirabegron group ($1581 vs. $1197 per month); this was primarily driven by medication cost. There was no difference in medical encounters. Adherence (39.1% vs. 33.8%) and persistence (103 vs. 90 days) were higher in mirabegron users. CONCLUSIONS: Among frail older adults with OAB, mirabegron use was associated with higher costs and potential improvements in treatment-taking behaviors, particularly with respect to treatment adherence, versus those initiating antimuscarinics.

A 12-Year Retrospective Study of the Prevalence of Anticholinergic Polypharmacy and Associated Outcomes Among Medicare Patients with Overactive Bladder in the USA.

BACKGROUND AND OBJECTIVE: Antimuscarinics, drugs with anticholinergic properties, are frequently prescribed for overactive bladder, and anticholinergic burden is associated with adverse events. The "Polypharmacy: Use of Multiple Anticholinergic Medications in Older Adults" (Poly-ACH) measure was developed by the Pharmacy Quality Alliance and is used by the Centers for Medicare and Medicaid Services. Using the Poly-ACH measure, we assessed the prevalence of anticholinergic polypharmacy among Medicare patients in the USA with overactive bladder and determined associations between polypharmacy and medical conditions, care, and spending. METHODS: This was a retrospective cohort study of Medicare beneficiaries with overactive bladder (coverage period: 2006-2017). Anticholinergic polypharmacy, measured by the Poly-ACH, was defined as concurrent use of two or more anticholinergics, each with two or more prescription claims on different dates of service for ≥ 30 cumulative days. Change in annual frequency of anticholinergic polypharmacy was assessed using logistic regression. Associations between anticholinergic polypharmacy over 3 years and falls, fractures, mental status, and medical care spending were assessed with longitudinal regression models. RESULTS: In total, 226,712 patients contributed 940,201 person-years of follow-up after overactive bladder diagnosis. The share of patients meeting the Poly-ACH definition was 3.3% in 2006 and 1.7% in 2017. Women and nursing home residents had higher risks of anticholinergic polypharmacy. Having 1 year or more of positive Poly-ACH status in the 3 years prior was associated with higher rates of all outcomes. CONCLUSIONS: Anticholinergic polypharmacy was uncommon among older adults with overactive bladder. Prevalence was higher among women and nursing home residents, and it was associated with negative outcomes, highlighting potential longitudinal implications of anticholinergic burden.

Antimuscarinic use among older adults with dementia and overactive bladder: a Medicare beneficiaries study.

OBJECTIVES: This study examined the incidence and predictors of antimuscarinic medication use including non-selective antimuscarinics among older adults with dementia and overactive bladder (OAB). METHODS: The study used a new-user cohort design involving older adults (≥65 years) with dementia and OAB based on 2013-2015 Medicare data. Antimuscarinics included non-selective (oxybutynin, tolterodine, trospium, fesoterodine) and selective (solifenacin, darifenacin) medications. Descriptive statistics and multivariable logistic regression models were used to determine the incidence and predictors of new antimuscarinic use including non-selective antimuscarinics, respectively. RESULTS: Of the 3.38 million Medicare beneficiaries with dementia, over one million (1.05) had OAB (31.03%). Of those, 287,612 (27.39%) were reported as prevalent antimuscarinics users. After applying continuous eligibility criteria, 21,848 (10.34%) incident antimuscarinic users were identified (77.6% non-selective; 22.4% selective). Most frequently reported antimuscarinics were oxybutynin (56.3%) and solifenacin (21.4%). Multivariable analysis revealed that patients ≥75 years, of black race, and those with schizophrenia, epilepsy, delirium, and Elixhauser's score were less likely to initiate antimuscarinics. Women, those with abnormal involuntary movements, bipolar disorder, gastroesophageal reflux disease, insomnia, irritable bowel syndrome, muscle spasm/low back pain, neuropathic pain, benign prostatic hyperplasia, falls/fractures, myasthenia gravis, narrow-angle glaucoma, Parkinson's disease, syncope, urinary tract infection and vulvovaginitis were more likely to initiate antimuscarinics. Further, patients with muscle spasms/low back pain, benign prostatic hyperplasia and those taking higher level anticholinergics had lower odds of receiving non-selective antimuscarinics, whereas white patients, black patients and those with schizophrenia and delirium were more likely to receive them. CONCLUSIONS: Nearly one-third of dementia patients had OAB and over one-fourth of them used antimuscarinics. Majority of the incident users were prescribed non-selective antimuscarinics with several demographic and clinical factors contributing to their use. Given the high prevalence of OAB among dementia patients, there is a need to optimize their antimuscarinic use, considering their vulnerability for anticholinergic adverse effects.

Prevalence and Factors Associated with Cumulative Anticholinergic Burden Among Older Long-Stay Nursing Home Residents with Overactive Bladder.

BACKGROUND: Overactive bladder (OAB), the primary cause of urinary incontinence in nursing homes, is commonly treated with anticholinergic medications; however, the elderly population is vulnerable to the adverse effects associated with anticholinergic burden. Given the relatively high prevalence of OAB among nursing home residents, it is important to understand the magnitude of anticholinergic burden in this population. OBJECTIVES: The objectives of this study were to (1) examine the prevalence of cumulative anticholinergic burden among long-stay nursing home (LSNH) residents with OAB; and (2) identify the factors associated with varying levels of cumulative anticholinergic burden. METHODS: This was a retrospective, cohort study using Minimum Data Set-linked Medicare claims data. Anticholinergic burden was determined based on the Anticholinergic Cognitive Burden scale and patient-specific dosing using defined daily dose. The Andersen Behavioral Model framework was used to identify the predisposing, enabling, and need factors associated with levels of anticholinergic burden. Multivariable logistic regression models were developed to determine the factors associated with levels of anticholinergic burden. RESULTS: A total of 123,308 LSNH residents with OAB were identified; 87.2% had some degree of anticholinergic burden and 27.3% had high cumulative burden. Multiple factors were associated with higher levels of burden, including younger age, female sex, and non-Hispanic White ethnicity (predisposing factors); dual eligibility, Southern geographic region, and rural residence (enabling factors); and a number of comorbidities and concomitant medications (need factors). CONCLUSIONS: This study revealed a high level of anticholinergic burden among LSNH residents. Multiple factors were associated with a high level of burden. There is a need to optimize the use of anticholinergics due to their significant safety concerns in the LSNH setting.

Increased Healthcare Resource Utilization and Direct and Indirect Costs in Patients with Depression and Comorbid Overactive Bladder: Evidence From a Retrospective, Matched Case-Control Cohort Analysis.

INTRODUCTION: This study sought to compare healthcare resource utilization (HCRU), costs, and workplace productivity among patients with depression, with and without overactive bladder (OAB). METHODS: This retrospective, case-control cohort analysis compares HCRU, costs, and workplace productivity among propensity score matched patients with depression and OAB (case cohort) and patients with depression without OAB (control cohort). Patients were aged 18 years or older, insured/on Medicare, and had diagnosed depression and an antidepressant medication claim pre index. First OAB-related event was index for cases; controls were assigned a proxy (study period 12 months). Comparisons of HCRU and costs and regression models assessed the relationship between OAB and costs. For the workplace productivity subset analyses cases and controls were balanced on baseline covariates for the short-term disability analyses but as they were unbalanced for the absentee analyses, multivariate regression analyses were used for this subset. RESULTS: The study criteria were met by 39,085 cases and 308,736 controls, from which, 37,997 patients were successfully matched 1:1 (mean age 55 years; 81% female). Most depression-related HCRU measures were similar across cohorts; however, outpatient visits, ER visits, and number of unique depression medications were significantly higher (all p < 0.05) among cases. Cases also had 13% higher total depression-related costs (p < 0.0001). Total mean (standard deviation [SD]) depression-related costs were $1796 ($4235) for cases versus $1597 ($3863) for controls (p < 0.0001). For workplace productivity (absentee data: cases [n = 686], controls [n = 642]; short-term disability data: cases [n = 4395], controls [n = 4433]) absentee outcomes were similar across cohorts. However, a higher percentage of cases used short-term disability benefits compared to controls (21.3% versus 16.9%; p < 0.0001) and cases experienced more case days (11.0 versus 8.6 mean days) and received higher mean payments than controls ($1226 versus $1033; p < 0.0001) in this subset. CONCLUSIONS: OAB was associated with 13% higher depression-related costs and 4.4% more cases used short-term disability benefits.

Racial and Socioeconomic Factors Influence Utilization of Advanced Therapies in Commercially Insured OAB Patients: An Analysis of Over 800,000 OAB Patients.

OBJECTIVE: To determine if racial and/or socioeconomic factors influence advanced therapy utilization for refractory overactive bladder (OAB) among the commercially insured. METHODS: We queried Optum, a national claims database, between 2003 and 2017. Non-neurogenic OAB patients were identified using ICD-9/10 diagnosis codes. Demographic and treatment data were collected, including oral medication therapies (anticholinergic, beta3 agonists), and advanced therapies (OnabotulinumtoxinA [BTX], Sacral Nerve Stimulation [SNS], percutaneous tibial nerve stimulation [PTNS]). Associations between patient sociodemographic factors and advanced therapy utilization were explored. RESULTS: Of 4,229,617 OAB patients, 807,612 (19%) received medical therapies, of which 95% received oral medications only and only 4.7% received advanced therapies. Asians had the lowest use of oral therapy use (14% vs 18%-19% in other races/ethnicities, P <0.05), and advanced therapy use (0.44% vs 0.71%-0.93%, P <0.05). Asians and Hispanics were least likely to utilize SNS therapy and most likely to use PTNS compared to Blacks and Whites. BTX use was similar between races/ethnicities (P <0.05). Female gender (OR 1.65 [CI 1.61,1.69]), younger age (<65) (OR 1.28 [1.25,1.31]), higher annual income ≥$40K (OR 1.09 [1.06,1.12]) and prior use of oral medications (OR 3.30 [3.21,3.38] for 1 medication) were significantly associated with receiving advanced therapies. Non-white race (OR 0.89 [0.87,0.91]), lower education level (less than a bachelor's degree) (OR 0.97 [0.94,0.99]), and Northeast region were associated with a lower likelihood of receiving advanced therapies (P <0.05 for all). CONCLUSION: Among commercially insured, racial and socioeconomic factors predict utilization of advanced OAB therapies, including race/ethnicity, age, gender, education level, and region.

Management of Patients with Overactive Bladder in Brazil: A Retrospective Observational Study Using Data From the Brazilian Public Health System.

INTRODUCTION: In Brazil, current data on the use of healthcare resources to manage individuals with overactive bladder (OAB) are lacking. This study aimed to characterize contemporary treatment and the economic burden among patients with OAB managed under the Brazilian public health system (Sistema Único de Saúde [SUS]). METHODS: Population-based data from January to December of 2015 were acquired from Brazil's public health database. Adults at least 18 years of age with an ICD-10 diagnostic code for OAB within the period were included. Records of outpatient visits, hospitalizations, and onabotulinumtoxinA injections were used to calculate estimates of resource use and costs (in Brazilian reals [R$]) among those with OAB (frequency [%] and mean (standard deviation [SD]) as appropriate). Patient identifiers were not available, so a record linkage methodology was used to match medical encounters to individuals. Pharmacologic management of OAB was informed by government medication purchases available from the official Brazilian government databases. RESULTS: During 2015, 26,640 patients with OAB were identified. All cohort members had at least one outpatient visit and 15,349 (57.6%) were hospitalized. Of the study cohort, 10.0% visited a general practitioner (GP), 41.3% visited a specialist, and 52.0% visited other non-medical healthcare practitioners within the year. Mean (SD) healthcare costs among the study cohort totaled R$355 (R$866) per patient per year; and were R$291 (R$654), R$27 (R$130), R$27 (R$30), and R$11 (R$17) for hospitalizations, GP, specialist, and non-medical healthcare practitioner visits per patient per year, respectively. Regional analysis of reported government medication purchases suggested that access to OAB treatments is highly limited. CONCLUSIONS: High resource use and costs were estimated among patients with OAB managed within the SUS. These data provide a snapshot of the management of patients with OAB in Brazil, with the patients seeking treatment under SUS likely representing a more burdened subpopulation.

The Relationship Between Anticholinergic Exposure and Falls, Fractures, and Mortality in Patients with Overactive Bladder.

BACKGROUND: Understanding risk factors associated with falls is important for optimizing care and quality of life for older patients. OBJECTIVE: Our objective was to determine the relationship between anticholinergic exposure and falls, fractures, and all-cause mortality. METHODS: An observational retrospective cohort study was conducted using administrative claims data from 1 January 2007 to 30 September 2015. Individuals aged 65-89 years newly diagnosed or treated for overactive bladder (OAB) were identified. Index date was the first OAB diagnosis or OAB medication prescription claim. Follow-up began on the index date and continued until death, disenrollment, or end of study period. The Anticholinergic Cognitive Burden (ACB) scale was used to define and quantify daily anticholinergic exposure and intensity. The primary study outcome was a combined endpoint of falls or fractures. All-cause mortality was a secondary endpoint. RESULTS: There were 113,311 patients with mean age of 74.8 ± standard deviation (SD) 6.2 years included. Current anticholinergic exposure was associated with a 1.28-fold increased hazard of a fall/fracture (95% confidence interval [CI] 1.23-1.32) compared with unexposed person-time, and past exposure was associated with a 1.14-fold increased hazard of a fall/fracture (95% CI 1.12-1.17). Compared with unexposed person-time, low-, moderate-, and high-intensity anticholinergic exposure was associated with a 1.04-fold (95% CI 1.00-1.07), 1.13-fold (95% CI 1.09-1.17), and 1.31-fold (95% CI 1.26-1.36) increased hazard of falls/fractures, respectively. A similar pattern was observed for all-cause mortality. CONCLUSIONS: Anticholinergic exposure is associated with an increased risk of falls or fractures in older patients and is an important consideration when evaluating treatment options for such patients with OAB.

Association between cumulative anticholinergic burden and falls and fractures in patients with overactive bladder: US-based retrospective cohort study.

OBJECTIVE: To estimate the association between cumulative anticholinergic burden and falls and fractures in patients with overactive bladder (OAB). DESIGN: A retrospective claims-based study (2007-2015) of patients with OAB; outcomes from a subset were contrasted to a non-OAB comparison. SETTING: United States, commercially and Medicare-insured population. PARTICIPANTS: 154 432 adults with OAB and 86 966 adults without OAB, mean age of 56 years, and 67.9% women. MAIN OUTCOME MEASURES: Cumulative anticholinergic burden, a unitless value representing exposure over time, was estimated over the 12 months pre-index ('at baseline') and every 6 months post index. Burden was categorised as no burden (0), low burden (1-89), medium burden (90-499) or high burden (500+). Unadjusted rates of falls or fractures were estimated, and the increased risk associated with anticholinergic burden (measured at the closest 6-month interval prior to a fall or fracture) was assessed using a Cox proportional hazards model and a marginal structural model. RESULTS: Median (IQR) baseline anticholinergic burden was 30 (0.0-314.0) and higher among older (≥65 years, 183 [3.0-713.0]) versus younger (<65 years, 13 [0.0-200.0]) adults. The unadjusted rate of falls or fractures over the period was 5.0 per 100 patient-years, ranging from 3.1 (95% CI 3.0-3.2) for those with no burden, to 7.4 (95% CI 7.1-7.6) for those with high burden at baseline. The adjusted risk of falls and fractures was greater with higher anticholinergic burden in the previous 6 months, with an HR of 1.2 (95% CI 1.2 to 1.3) for low burden versus no burden, to 1.4 (95% CI 1.3 to 1.4) for high versus no burden. Estimates from marginal structural models adjusting for time-varying covariates were lower but remained significantly higher with a higher anticholinergic burden. Rates of falls and fractures were approximately 40% higher among those with OAB (vs those without). CONCLUSION: Higher levels of anticholinergic burden are associated with higher rates of falls and fractures, highlighting the importance of considering anticholinergic burden when treating patients with OAB.

Impact of Coexisting Overactive Bladder in Medicare Patients With Dementia on Clinical and Economic Outcomes.

BACKGROUND: Patients with dementia commonly suffer from symptoms of overactive bladder (OAB); however, limited research exists on the clinical impact of coexisting OAB among patients with dementia. As such, the objective of this study was to examine the impact of OAB on clinical outcomes, health-care resource use, and associated costs among patients with dementia. METHODS: We conducted a retrospective cohort analysis of patients with dementia using 3861 matched pairs of patients with and without OAB. Analyses were based on administrative claims data from January 1, 2007, to September 30, 2015, and compared clinical outcomes, health services use, and associated costs. RESULTS: Patients with dementia and OAB were more likely than those without OAB to have least one fall (incidence rate ratio [IRR]: 1.43, 95% confidence interval [CI], 1.22-1.68, P < .001), fracture (IRR: 1.23, 95% CI, 1.05-1.44, P = .008), combined fall/fracture (IRR: 1.25, 95% CI, 1.11-1.42, P < .001), or urinary tract infection (IRR: 2.75, 95% CI, 2.55-2.96, P < .001). Patients with dementia and OAB demonstrated greater utilization of all-cause encounter types compared to similar patients without coexisting OAB (P < .01). All-cause and dementia-related total health-care costs were approximately 23% (95% CI, 0.19-0.28, P < .001) and 13% (95% CI, 0.05-0.20, P = .001), respectively, greater than similar patients without coexisting OAB. CONCLUSION: Coexisting OAB was associated with impacts on clinical outcomes, health-care resource utilization, and costs in patients with dementia.

Health and functional status, health events, use of healthcare services and costs associated with overactive bladder among the medically complex vulnerable elderly in the US.

AIMS: To assess the prevalence of overactive bladder (OAB) among medically complex vulnerable elderly (MCVE) patients in the United States and to compare health status measures, functional status, healthcare events, use of healthcare services and costs between MCVE patients with and without OAB. METHODS: Using the 2001-2010 Medicare Current Beneficiary Surveys, we defined the MCVE as those respondents who were ≥65 years old with scores ≥3 on the Vulnerable Elders Survey-13. OAB diagnosis codes or self-reported use of antimuscarinic medications were used to identify MCVE individuals with OAB. Multiple regression analyses were used to estimate the adjusted relationship between OAB and the outcome measures. RESULTS: The annual prevalence of OAB among the MCVE increased from 9.6% in 2001 to 13.5% in 2010. MCVE individuals with OAB were more likely to have experienced falls or fractures (odds ratio [OR] = 1.6; 95% confidence interval [CI]: 1.3-2.0), urinary tract infections (OR = 4.3; 95% CI: 3.5-5.4), institutionalization (OR = 1.9; 95% CI: 1.4-2.5), limitations in activity of daily living (ADL) (OR = 1.4; 95% CI: 1.1-1.7) and instrumental ADL (OR = 1.5; 95% CI: 1.2-2.0), hospital admission (OR = 1.6; 95% CI: 1.3-2.0) and emergency department admissions (OR = 1.6; 95% CI: 1.3-2.0) than those without OAB. MCVE individuals with OAB incurred, on average, $7188 (2013 dollars) more in healthcare costs than those without OAB. DISCUSSION/CONCLUSIONS: The prevalence of OAB in the MCVE population increased over time. OAB is associated with substantial clinical and economic burden. Further research is warranted to understand whether better management of the MCVE population with OAB may reduce healthcare resource use.

Assessment of the long-term outcome of TVT procedure for stress urinary incontinence in a female population: results at 17 years' follow-up.

INTRODUCTION AND HYPOTHESIS: To assess the outcome of the tension-free vaginal tape (TVT) procedure in female patients with urodynamic stress urinary incontinence at 17 years follow-up. METHODS: We carried out a prospective study at the 2nd Department of Obstetrics and Gynecology, Aretaieio Hospital, University of Athens, Greece. Patients who had undergone a TVT procedure 17 years ago. The follow-up assessment included gynecological examination, urinalysis, cough stress test in the lithotomy and/or upright position, filling and voiding cystometry, and uroflow. Also, all patients were required to complete the Patient Satisfaction Questionnaire (PSQ). RESULTS: Out of the 61 initial patients, 56 were available for follow-up. Objective cure rate was 83.9% (47/56) at 17 years follow-up. Subjective cure rate was 78.6% (44/56), subjective improvement was 8.9%, and failure rate was 12.5%. Frequency was present in 39.3% of patients, overactive bladder symptoms were present in 30.3% of patients and urge urinary incontinence was reported by 12.5% of patients. Difficulty emptying the bladder was reported by 10 patients (17.8%) and recurrent urinary tract infection was seen in 3.5% of patients. There was one case of TVT erosion to the vaginal mucosa, which was managed conservatively. CONCLUSIONS: The TVT procedure for the management of stress urinary incontinence in women maintains its efficacy in the long term, having an objective cure rate of 83.9% and a subjective cure rate of 78.6% at 17 years' follow-up, with a very low complications rate.

Socioeconomic status and health-related quality of life among adults and older with overactive bladder.

OBJECTIVE: To study the effect of socioeconomic status (SES) on health-related quality of life (HRQoL) among persons with overactive bladder (OAB). DESIGN: A randomized HRQoL study was conducted from the year 2014 until the year 2016 based on the OAB pathology department of the regional clinical diagnostics center. SETTING: The medical institutions where the study was conducted had outpatient care. PARTICIPANTS: The simple response frequency was 81%. A total of 1893 men and women with OAB aged 35-85 (average 58.3 years) were selected by blind random sampling. Included into the group of examined individuals were persons who diagnosis provided after the examination was OAB. INTERVENTION: Evaluation of HRQoL was conducted using the SF-6D questionnaire. The OAB diagnosis was confirmed using the OAB-questionnaire and uroflowmetry. MAIN OUTCOME MEASURE(S): We hypothesized that the impact of SES on the HRQoL of patients with OAB has significant features. RESULTS: Described for the first time were HRQoL measures in various SES levels within different ages of people suffering from OAB. The strongest relationship was identified between education level, professional activity and HRQoL measures; meanwhile the weakest relationship was between income and HRQoL measures. We also confirmed the efficiency of evaluating HRQoL while using SF-6D and SRH as an external standard. CONCLUSION: The improvement of HRQoL in persons with OAB is contingent upon increment in their level of awareness about the methods of OAB treatment and the effectiveness of treatment for severe symptoms of LUT pathology, increased social support and, possibly, physical activity.

Management of Idiopathic Overactive Bladder Syndrome: What Is the Optimal Strategy After Failure of Conservative Treatment?

CONTEXT: A considerable number of patients affected by the overactive bladder syndrome (OAB) do not respond to pharmacotherapy and bladder training due to unsatisfactory response or intolerability. OBJECTIVE: To review the available literature assessing therapeutic effect of the available third-line treatment modalities for OAB. EVIDENCE ACQUISITION: PubMed, Medline, and Cochrane databases were searched for all studies comparing outcomes of the available third-line treatment modalities for OAB. EVIDENCE SYNTHESIS: Several minimally invasive surgical procedures are available for patients with refractory OAB. These therapies include intravesical botulinum toxin type A, posterior tibial nerve stimulation, and sacral neuromodulation. CONCLUSIONS: None of the mentioned therapeutic modalities shows strong superiority over another. If the results of one therapy are not satisfactory, switching to another third-line treatment can be attempted. The treatment algorithm is dependent on several factors, including age, comorbidity, patient preference, surgical expertise, and financial concerns. All these factors should be taken into consideration before initiation of treatment. PATIENT SUMMARY: In the management of drug-resistant overactive bladder syndrome, the different minimally invasive treatments that are available are equal. If the results of one therapy are not satisfactory, switching to another treatment can be attempted. The treatment algorithm is dependent on several factors, including age, comorbidity, patient preference, surgical expertise, and financial concerns.

Is it Safe to Reduce Water Intake in the Overactive Bladder Population? A Systematic Review.

PURPOSE: Overactive bladder imposes a significant socioeconomic burden on the health care system. It is a commonly held belief that increased fluid intake (8 glasses of water per day) is beneficial for health. However, increased fluid intake exacerbates overactive bladder symptoms. Thus, it is imperative that clinicians appropriately educate patients for whom increased water intake may be detrimental (women with overactive bladder), in contrast to patients with comorbidities that necessitate increased water intake (nephrolithiasis). We systematically reviewed the literature to determine the potential health advantages of increased water intake and identify specific subpopulations that need increased hydration. MATERIALS AND METHODS: We systematically reviewed published articles from 1972 through 2017 on PubMed® and the Cochrane Library. The data were reviewed independently by 2 individuals. Studies were included if they explored water intake in relation to the risk of a particular disease. RESULTS: Level 1 evidence supported increased fluid intake in patients with nephrolithiasis. There was no available evidence to support increased fluid intake in patients with cardiovascular disease, constipation, venous thromboembolism, headaches, cognitive function or bladder cancer. Dehydration may exacerbate some conditions, specifically chronic constipation and headache intensity. Increased fluid intake may have a role in preventing stroke recurrence but not in preventing primary stroke. CONCLUSIONS: The available reviewed literature suggests no benefit to drinking 8 glasses of water per day in patients without nephrolithiasis. Also, excess fluid intake can exacerbate symptoms of overactive bladder.

The economic burden of overactive bladder (OAB) and its effects on the costs associated with other chronic, age-related comorbidities in the United States.

AIMS: The prevalence of OAB increases with age and is associated with several chronic comorbidities. However, the impact of OAB on the healthcare costs of patients with such comorbidities is not well-understood. This study aimed to quantify the impact of OAB on healthcare costs and assess the potential moderating effects of OAB on the costs of patients with chronic comorbidities. METHODS: Adults with evidence of OAB/OAB-related therapy between 1/1/2008-12/31/2013 were identified from two large, administrative claims databases. Per-patient-per-month (PPPM) expenditures for OAB cases were estimated and compared to those of propensity score-matched subjects without OAB. Costs were modeled using ordinary least squares regression including main effects and interactions of chronic depression, dementia, diabetes, hypertension, and osteoporosis with OAB. Values for the comparisons were calculated on the original dollar scale using smearing estimators. RESULTS: A total of 110 059 pairs of OAB cases and matched non-OAB controls were identified. The mean, multivariable-adjusted, PPPM all-cause costs of OAB cases from the model without interactions were $3003, compared to $1123 for matched controls (P < 0.0001). In the model assessing the interactions of chronic comorbidities with OAB, those OAB patients with comorbid depression, dementia, diabetes, hypertension, and osteoporosis incurred significantly higher costs than controls with these comorbidities. The synergistic effect of these interactions was estimated to be $95-$574 PPPM. CONCLUSIONS: Within this US-based population, the healthcare costs of OAB patients were more than 2.5 times those of similar patients without OAB. Additionally, patients with OAB and chronic, age-related comorbidities incurred higher healthcare costs than non-OAB controls with the same comorbidities.

Predictors for detrusor overactivity following extensive vaginal pelvic reconstructive surgery.

AIM: This study aims to identify the predictors for detrusor overactivity (DO) in women following extensive vaginal pelvic reconstructive surgery (PRS) for advanced pelvic organ prolapse (POP). METHODS: We enrolled 1503 women who had prolapse POP-Q stage ≥ 3 and underwent vaginal PRS with or without MUS from January 2006 to December 2015. All subjects completed a 72-h voiding diary, IIQ-7, UDI-6, POPDI-6, and PISQ-12. Urodynamics (UDS) was performed pre- and post-operatively. RESULTS: Among 1503 women, 56 patients were excluded due to incomplete data. Women who had trans-vaginal mesh were 1083 of 1447 (74.8%) and concomitant MUS were 353 (24.4%). Pre-operative DO were 245 (16.9%) and 24.5% (60/245) of them continued to have persistent DO post-operatively. Women who had normal pre-operative stable detrusor were 1202 (83.1%) and 3.5% (30/1202) developed de novo DO post-operatively. The overall incidence of post-operative DO was 6.2% (90/1447). Patients with age ≥66 year, neurological factors like Cerebrovascular accident and Parkinsonian disease, pre-operative bladder outlet obstruction (BOO) maximum urethral closure pressure (MUCP) ≥60 cmH2 O, Maximum flow rate (MFR) <15 mL/s and detrusor at maximum flow (Dmax) ≥20 cmH2 O) and post-void residue (PVR) ≥200 mL hold a significant higher risk of developing DO either persistent or de novo following PRS. CONCLUSION: Age ≥66 year, neurological factors like CVA and Parkinsonian disease, pre-operative MUCP ≥60 cmH2 O, MFR < 15 mL, Dmax ≥ 20 cmH2 O, and PVR ≥ 200 mL are independent risk factors for developing post-operative DO following vaginal PRS for advanced POP.

Impact of coexisting overactive bladder in Medicare patients with osteoporosis.

BACKGROUND: Osteoporosis and overactive bladder (OAB) are prevalent conditions in older adults and are independent risk factors for falls and fractures. A paucity of evidence exists examining the impact of coexisting OAB in patients with osteoporosis. OBJECTIVE: To examine the impact of OAB on healthcare resource utilization (HRU), clinical outcomes, and healthcare costs among older adult patients with osteoporosis. METHODS: This retrospective analysis compared patients with osteoporosis with and without OAB. Patients with an osteoporosis diagnosis, enrolled in a Medicare Advantage plan, and aged 65-89 inclusive were eligible. Incident OAB among patients with prevalent osteoporosis was identified. A comparison group of patients with osteoporosis but no evidence of OAB was propensity score matched on baseline characteristics. Fall and/or fracture outcomes, HRU and healthcare costs were evaluated during 12 months of follow-up. Bivariate comparisons of outcomes were conducted. Ordinary least squared regression was used to examine the relationship between OAB and total healthcare costs. RESULTS: After matching, 5,526 patients in each group were included. Patients with osteoporosis and OAB demonstrated greater all-cause HRU across all encounter types compared to patients without OAB (all P values<0.001). Patients with osteoporosis and OAB had a greater frequency of any fall/fracture (17.7% vs. 14.9%, P<0.001). Patients with osteoporosis and OAB had 35% greater all-cause total healthcare costs than patients without OAB (P<0.001). CONCLUSIONS: Patients with OAB and osteoporosis had significantly greater all-cause HRU and costs. Falls and fractures were significantly more common in patients with osteoporosis and OAB compared to patients with osteoporosis without OAB.

Prevalence of overactive bladder and its impact on quality of life in 1025 patients with type 2 diabetes in mainland China.

AIMS: This study examined the prevalence of overactive bladder (OAB) and investigated the impact of OAB on quality of life (QOL) in patients with type 2 diabetes in Mainland China. METHODS: A total of 1025 patients with type 2 diabetes were surveyed. Patients were grouped into no OAB, dry OAB, and wet OAB groups according to the presence of OAB and urge incontinence. Descriptive analyses, one-way analysis of variance (ANOVA) and multivariable regression models were conducted to assess the prevalence of OAB and the effect of OAB on QOL. RESULTS: The prevalence of OAB among patients with type 2 diabetes was 13.9% (with dry OAB, 6.1%; with wet OAB, 7.8%). Multivariable regression models showed that OAB symptoms caused significant deterioration of the physical and mental aspects of QOL. Compared with dry OAB, wet OAB further decreased the mental aspect of QOL. Moreover, the effect sizes of the impacts of dry and wet OAB on QOL were larger than those of diabetic neuropathy or retinopathy, diabetes duration, or urinary tract infection history. CONCLUSIONS: OAB is more common in patients with type 2 diabetes than in the general population and substantially decreases patient QOL.
