RESUMO
OBJECTIVE: We summarized the evidence evaluating the cost-effectiveness of sacral neuromodulation (SNM) versus onabotulinumtoxinA (BONT/A) in the treatment of refractory overactive bladder (OAB) among women. METHODS: We searched PubMed Medline (1946-2019), EMBASE (1947-2019), Web of Science (1900-2019), Clinical Trials.gov, reviewed references of included studies, and Cochrane subsets of CDSR, DARE, CENTRAL, and NHSEED. We included cost-utility and cost-effectiveness analyses or decision analysis comparing SNM versus BONT/A in women with nonneurogenic refractory OAB. Primary outcomes included incremental cost-effectiveness ratios (ICERs), reported as cost per quality-adjusted life year (QALY), which were abstracted or calculated. RESULTS: Five studies met the inclusion criteria. Three studies were industry supported. Two studies of high quality found BONT/A to be dominant over SNM (ICER range of $415,571/QALY at 5 years and $236,370/QALY at 10 years). This trend was further supported by a third study of high quality that favored BONT/A because SNM was not cost-effective (ICER, $116,427/QALY at 2 years). In contrast, 2 other studies of lower quality found that SNM was cost-effective or dominant in comparison to BONT/A (ICER range, $3,717/QALY to 15,226/QALY at 10 years). In general, models were sensitive to treatment duration, intervention setting, and lacked robust data on long-term outcomes. CONCLUSIONS: OnabotulinumtoxinA is more cost-effective for managing refractory OAB when compared with SNM. However, it remains unclear whether this finding holds true long term for what is considered a lifelong condition.

PURPOSE: We aimed to understand the reasons patients choose to pursue third-line overactive bladder (OAB) therapy. MATERIALS AND METHODS: We conducted a mixed methods study that included patient interviews and survey data. Eligible patients were diagnosed by symptoms, had tried behavioral modifications, and OAB medications enrolled from October 2018 to August 2019. In addition to interviews, patients completed 4 surveys: the Pelvic Floor Distress Inventory, Overactive Bladder Questionnaire Short Form, Life Orientation Test-Revised, and a patient confidence in the health care system survey. Qualitative interview data were analyzed thematically. Logistic regression and chi-square analysis was used to analyze survey data. RESULTS: A total of 69 patients were consented, 4 withdrew, and 51 completed both interview and survey data. Overall 55% of patients were Caucasian, 45% were African American, and their average age was 71 (SD=10.4); 75% intended to pursue third-line OAB therapy and 31 (61%) expressed interest in a specific third-line therapy. Major interview themes included a desire for a better quality of life, embarrassment with accidents, and problems with medication. Themes leading patients away from third-line OAB treatment included concern about invasiveness and side effects of treatments, and restrictions to accessing care. CONCLUSIONS: Most patients desired to progress to third-line OAB therapy, were motivated by embarrassment, but were concerned about treatment side effects. We found that economic burden of OAB treatment is associated with patient interest in and decision to receive third-line therapies to include onabotulinumtoxinA and percutaneous tibial nerve stimulation. Improved quality of life, medication frustration, and concerns about side effects of further therapy are themes patients identified when patients considered third-line overactive bladder therapy.

OBJECTIVE: The aim of this study was to evaluate national patterns of care for women with overactive bladder (OAB) in an administrative data set and identify potential areas for improvement. METHODS: We performed an analysis using the OptumLabs Data Warehouse, which contains deidentified administrative claims data from a large national US health insurance plan. The study included women, older than 18 years, with a new OAB diagnosis from January 1, 2007, to June 30, 2017. We excluded those with an underlying neurologic etiology, with interstitial cystitis/painful bladder syndrome, were pregnant, or did not have continuous enrollment for 12 months before and after OAB diagnosis. Trends in management were assessed via the Cochran-Armitage test. Time to discontinuation among medications was compared using t test. RESULTS: Of 1.4 million women in the database during the study time frame, 60,246 (4%) were included in the study. Median age was 61 years [interquartile range (IQR), 50-73], and median follow-up was 2.6 years (IQR, 1.6-4.2). Overall, 37% were treated with anticholinergics, 5% with beta-3 agonists, 7% with topical estrogen, and 2% with pelvic floor physical therapy; 26% saw a specialist; and 2% underwent third-line therapy. Median time to cessation of prescription filling was longer for beta-3 agonists versus anticholinergics [median, 4.1 months (IQR, 1-15) vs 3.6 months (IQR, 1-10); P < 0.0001]. Use of third-line therapies significantly increased over the study time frame, from 1.1% to 2.2% (P < 0.0001). CONCLUSIONS: Most of the patients do not continue filling prescriptions for OAB medications, and a minority of patients were referred for specialty evaluation. Although third-line therapy use is increasing, it is used in a small proportion of women with OAB. Given these patterns, there may be underutilization of specialist referral and other OAB therapies.

PURPOSE OF THE REVIEW: This paper discusses the recent evidence supporting beta 3 adrenergic agonists as the preferred pharmacological management of overactive bladder syndrome. RECENT FINDINGS: Mirabegron has a similar efficacy profile to first-line antimuscarinics with favorable adverse effects profile. Treatment of OAB with beta-3 adrenergic agonist should be favored in patients at higher risk of anticholinergic adverse events. The efficacy and tolerability of beta-3 adrenergic agonists are consistently reported in older OAB patients, whether used alone or with other antimuscarinics. Mirabegron is cost-effective in treating OAB unless the symptoms were severe or refractory. Combination therapy of mirabegron and other pharmacotherapy has proven to be efficient in controlling OAB symptoms without inducing serious add-on adverse effects. While beta-3 adrenergic agonists bear favorable advantages in OAB treatment, physicians should perform a thorough and careful pre-treatment planning to optimize treatment benefits and adherence.

OBJECTIVE: To evaluate utilization of third-line overactive bladder (OAB) treatments including percutaneous tibial nerve stimulation (PTNS), sacral nerve stimulation (SNS), and intradetrusor botulinum toxin A (BTX) among privately insured patients and examine factors associated with their use. MATERIALS AND METHODS: Using MarketScan claims (2015-2017), we identified patients who underwent third-line OAB treatments based on procedure codes. Factors of interest included location, age, health plan, among others. We fit multivariable logistic regression models to estimate associations between pertinent factors with receipt of PTNS and SNS relative to BTX and associations between provider type and practice location with each treatment modality. RESULTS: We identified 7383 patients (mean age 50.9) in our cohort. SNS was used most frequently (n = 3602, 48.8%), while PTNS was used least frequently (n = 955, 12.9%). PTNS patients were more likely to reside in metropolitan areas (vs BTX: OR 1.6, 95%CI 1.3-2.1; vs SNS: OR 2.2, 95%CI 1.7-2.8), be aged 55 years or older (vs BTX: 54% vs 47%, OR 1.6, 95%CI 1.2-2.1; vs SNS: 54% vs 45%, OR 1.6, 95%CI 1.2-2.0), and be covered under a health maintenance organization (vs BTX: 17% vs 10%; vs SNS: 17% vs 10%, P <.01). Urologists were most likely to perform SNS, and gynecologists were most likely to perform BTX. 91% of PTNS procedures were performed in office settings. CONCLUSION: Among patients receiving third-line OAB treatment, PTNS was used infrequently. PTNS utilization was concentrated within urban areas, and among older patients and those covered by cost-conscious health maintenance organizations.

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.

PURPOSE: We aimed to determine the real world safety and cost of third line overactive bladder therapies, including onabotulinumtoxinA and sacral neuromodulation. MATERIALS AND METHODS: We performed an all-inclusive, population based cohort study of third line therapies of overactive bladder (sacral neuromodulation or onabotulinumtoxinA) using the statewide surgical data captured in the New York Statewide Planning and Research Cooperative System. The main outcome measures were 30-day safety events, and 1 and 3-year health care utilization costs. Propensity score matching was done to control for confounding factors and comparative analyses of safety events were also performed. RESULTS: Our cohort included 2,680 patients, of whom 1,328 underwent sacral neuromodulation and 1,352 received onabotulinumtoxinA from January 1, 2013 through December 31, 2016. Average ± SD age was 61.7 ± 16.3 years and 82.7% of the patients were female. Sacral neuromodulation implantation led to re-intervention in 15.8% of cases within 1 year and in 26.1% at 3 years. In this comparative analysis patients who received onabotulinumtoxinA therapy were at higher risk for urinary tract infection, hematuria, urinary retention and an emergency room visit compared to those treated with sacral neuromodulation. The overall cost of onabotulinumtoxinA was lower than the cost of the sacral neuromodulation device (cost at 1 year $2,896 vs $15,343 and at 3 years $3,454 vs $16,189, each p <0.01). CONCLUSIONS: Sacral neuromodulation implantation was more expensive than onabotulinumtoxinA injection. However, patients who underwent sacral neuromodulation had a lower complication rate than patients treated with onabotulinumtoxinA. A quality improvement collective database must be created to track information on onabotulinumtoxinA and sacral neuromodulation treatment. This would help generate better performance and comparative data for patient and physician decision making.

AIMS: Sacral neuromodulation (SNM) is a standard therapy for refractory overactive bladder (OAB). Traditionally, SNM placement involves placement of an S3 lead with 1-3 weeks of testing before considering a permanent implant. Given the potential risk of bacterial contamination during testing and high success rates published by some experts, we compared the costs of traditional 2-stage against single-stage SNM placement for OAB. METHODS: We performed a cost minimization analysis using published data on 2-stage SNM success rates, SNM infection rates, and direct reimbursements from Medicare for 2017. We compared the costs associated with a 2-stage vs single-stage approach. We performed sensitivity analyses of the primary variables listed above to assess where threshold values occurred and used separate models for freestanding ambulatory surgery centers (ASC) and outpatient hospital departments (OHD). RESULTS: Based on published literature, our base case assumed a 69% SNM success rate, a 5% 2-stage approach infection rate, a 1.7% single-stage approach infection rate, and removal of 50% of non-working single-stage SNMs. In both ASC ($17 613 vs $18 194) and OHD ($19 832 vs $21 181) settings, single-stage SNM placement was less costly than 2-stage placement. The minimum SNM success rates to achieve savings with a single-stage approach occur at 65.4% and 61.3% for ASC and OHD, respectively. CONCLUSIONS: Using Medicare reimbursement, single-stage SNM placement is likely to be less costly than 2-stage placement for most practitioners. The savings are tied to SNM success rates and reimbursement rates, with reduced costs up to $5014 per case in centers of excellence (≥ 90% success).

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.

AIM: To assess the cost-effectiveness of onabotulinumtoxinA (onabotA), implantable sacral nerve stimulation devices, percutaneous tibial nerve stimulation, anticholinergic medications and mirabegron compared with best supportive care (BSC) for management of refractory overactive bladder (OAB). METHODS: A Markov model was developed to compare the cost-effectiveness of treatment options with BSC over a 10-year time horizon. Resource utilization, discontinuation rates and costs were derived from unpublished and published sources. Quality-adjusted life-years (QALYs) and incremental cost-effectiveness ratios were reported. RESULTS: Treatment with onabotA 100U produced the largest gain in QALYs (7.179) and lowest estimated incremental cost-effectiveness ratio ($32,680/QALY) of all assessed treatments compared with BSC. CONCLUSION: Compared with BSC, onabotA 100U was the most cost-effective treatment option for patients with refractory OAB.

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.

OBJECTIVE: To quantify the burden associated with overactive bladder (OAB) within a commercially-insured United States (US) population. METHODS: Adults with OAB identified from the MarketScan databases (2008 to 2013) were propensity score matched 1:1 to non-OAB controls. Per-patient-per-month (PPPM) direct healthcare costs, and indirect costs attributable to workplace absence and short-term disability (STD), were estimated. RESULTS: Adjusted PPPM healthcare costs were higher for OAB patients than matched controls for both direct costs ($3003 vs $1123; Pâ<â0.0001) and indirect costs due to STD ($114 vs $98; Pâ<â0.05). There was no difference in the indirect costs due to absence between the OAB cases and controls. CONCLUSIONS: The direct healthcare costs of OAB patients are substantial. Additional research is needed to quantify the impact of OAB on workplace productivity. Improved management of OAB symptoms may reduce costs and enhance patient quality of life.

Overactive bladder (OAB) is a symptom-driven condition with economic burden estimated to be on the order of several hundred dollars or euros per patient in some North American and European countries. This work reviews recently published economic models to evaluate how health states are defined, what cost components are considered, and what utility values are used to estimate the cost effectiveness of OAB pharmacotherapies, botulinum toxin, or sacral neuromodulation. It was found that no clear standard exists for determining OAB health states, although most were defined by some measure of incontinence frequency. Costs of physician visits and incontinence pads were included in nearly all models; however, OAB-associated depression and nursing home costs were rarely included, despite being large cost drivers of global economic burden studies. Utility values used in the models ranged from 0.544 to 0.933, highlighting the uncertainty associated with how OAB patients value health-related quality of life. More research is warranted so that health states providing delineations among OAB symptom severity and quality of life are clinically and economically meaningful as well as meaningful to affected patients.

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.

INTRODUCTION AND HYPOTHESIS: To determine if Onabotulinumtoxin A (Botox®) should be offered as a first-line therapy for the treatment of overactive bladder (OAB), even before prescribing anticholinergics. METHODS: We performed a cost-effectiveness analysis modeling the following clinical options: no treatment, non-selective anticholinergics, selective anticholinergics, and Botox®. The model timeframe was 2 years to allow Botox® reinjection and discontinuation of anticholinergics. Multiple efficacy levels included response improvement by < 50%, 50%, 75%, and 100%. Botox® reinjection was allowed at 6 months if < 50% efficacy. Botox® complications and anticholinergic side effects were noted. We modeled up to one medication switch. No crossover from Botox® to anticholinergics or vice versa was allowed, and failures remained with refractory untreated overactive bladder. Medical literature data were used for model parameter values. Costs are 2016 $US. RESULTS: Botox® costs more than non-selective anticholinergics and less than selective anticholinergics in models with and without refractory overactive bladder costs. Botox® had the highest effectiveness (1.763 quality-adjusted life years). Using incremental cost-effectiveness ratios, Botox® was found to be cost-effective in models with and without refractory costs ($12,428.75 and $14,437.01, respectively). In both models, Botox® cost less and was more effective than selective anticholinergics, which were "dominated." Over 2 years, subjects averaged 15.6 and 14.3 months on selective and non-selective anticholinergics, respectively, and patients averaged 2.2 Botox® injections. Model results were unchanged with variation of input parameter estimates in sensitivity analyses. CONCLUSIONS: Botox® is a cost-effective therapy for overactive bladder and should be further explored as a first-line option in the treatment paradigm.

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.

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.

AIMS: Overactive bladder (OAB) affects up to 17% of the United States (US) population. This study aimed to synthesize estimates of direct and indirect costs of OAB in the US and compare costs among those with and without OAB. METHODS: A systematic review was performed using MEDLINE/PubMed and Embase, from 2003 to 2016, following PRISMA guidelines. The target population was adults with idiopathic OAB or urge urinary incontinence from the US. Data were extracted on study and patient characteristics, all-cause and OAB-specific direct costs, resource use, and indirect costs. Costs were inflated to a common price year of 2016 USD. RESULTS: Eighteen studies were included. Mean insurer paid all-cause total direct healthcare costs ranged from 8168 to 15 569 USD, and OAB-specific costs ranged from 656 to 860 USD per-patient annually. Estimates of the incremental costs for OAB patients compared to non-OAB comparators ranged from 43% to 117%. One study estimated total annual indirect costs of OAB at 11 134 USD per-patient. CONCLUSIONS: The range of direct healthcare costs reported for managing patients with OAB varied, but was relatively small given the differing contributing data sources, study designs, and cost definitions. Direct costs were consistently higher among patients with OAB versus non-OAB comparisons, from a 1.4- to >2-fold increase annually. OAB-specific costs made up a small proportion of all-cause costs, highlighting the clinical and economic impact of OAB-related conditions such as falls, urinary tract infection, and depression. Few studies were identified that examined the indirect costs of OAB in the US.

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.

BACKGROUND: Despite several new medications being Food and Drug Administration-approved for overactive bladder (OAB) and new prescription drug payment programs, there are limited population-based data regarding OAB medication use among older adults. OBJECTIVES: To examine: (1) impacts of new medications and $4 generic programs on time trends for OAB-related medication dispensing for older adults in the United States; (2) differences by age and sex; and (3) temporal changes in OAB-related medication payments. METHODS: Using Truven Health Analytics' Medicare Supplemental Database (2000-2015), we analyzed OAB-related medication claims for 9,477,061 Medigap beneficiaries age 65-104. We estimated dispensing rates (per 1000 person-months), assessed dispensing trends using interrupted time-series methods, compared dispensing rates by age and sex, and summarized payment trends. RESULTS: From 2000 to 2015, 771,609 individuals filled 13,863,998 OAB-related prescriptions. During 2000-2007, 3 new extended-release medications became available (tolterodine, darifenacin, solifenacin), leading to increases in overall OAB-related dispensing rates by 19.1 (99% confidence interval, 17.0-21.2), a 92% increase since 2000; overall rates remained stable during 2008-2015. By 2015, the most common medications were oxybutynin (38%), solifenacin (20%), tolterodine (19%), and mirabegron (12%). Dispensing rates peaked at age 90 (rate, 53.4; 99% confidence interval, 53.1-53.7). Women had higher rates than men at all ages (average ratewomen-ratemen, 22.0). The gap between upper and lower percentiles of medication payments widened between 2008-2015; by 2015, 25% of reimbursed dispensed prescriptions had total payments exceeding $250. CONCLUSIONS: Medication-specific dispensing rates for OAB changed when new alternatives became available. Recent changes in utilization and cost of OAB medications have implications for clinical guidelines, pharmacoepidemiologic studies, and payment policies.
