RESUMEN
OBJECTIVES: Between 2013 to 2019, several all-oral direct-acting antivirals (DAAs) were launched with the potential to cure patients with hepatitis C virus (HCV). They generated economic value in terms of the health gains for patients and cost-savings for the US healthcare system. We estimated the share of this value allocated to 4 manufacturers vs society. METHODS: For 2015 to 2019, we estimated the incremental impact of DAAs on HCV health outcomes and costs. We used the Center for Disease Analysis Foundation Polaris Observatory database to estimate utilization. Per-patient projections of lifetime quality-adjusted life-years (QALYs) gained and medical costs avoided were based on a standard 9-state HCV disease-progression model for DAA treatment vs alternatives. Annual QALY gains were valued at $114 000 per QALY. Outcomes and costs were discounted at 3%. Estimated revenues were based on reported sales. RESULTS: An estimated 1 080 000 patients received DAAs: 81.5% would not have received the pre-DAA standard of care. On average, these patients were projected to gain 4.4 QALYs and save $104 400 in lifetime healthcare costs, generating $531.8 billion in value. Those who would have received treatment gained 1.7 QALYs and saved $41 500 in lifetime costs, generating $47.4 billion in economic value. As treatment costs fell nearly 75%, the 4 manufacturers reported $37.4 billion from DAA sales-an allocation of 6.5% of the total value. CONCLUSIONS: The significant majority (â¼90%) of the economic value of curing HCV with DAAs were health benefits to patients and net cost-savings to society. DAA manufacturers received a minority share (6.5%) of the aggregate economic value generated.

Although current guidelines recommend that nearly all patients with chronic hepatitis C virus (HCV) infection receive treatment, a substantial proportion remain untreated. We conducted an administrative claims analysis to provide real-world data on treatment patterns and characteristics of treated versus untreated patients among individuals with HCV in the United States. Adults with an HCV diagnosis from 01 July 2016 through 30 September 2020 and continuous health plan enrolment for 12 months before and ≥1 month after the diagnosis date were identified in the Optum Research Database. Descriptive and multivariable analyses were conducted to evaluate the association between patient characteristics and the rate of treatment. Of 24,374 patients identified with HCV, only 30% initiated treatment during follow-up. Factors associated with increased rate of treatment included younger age versus age 75+ (hazard ratio [HR] 1.50-1.83 depending on age group), commercial versus Medicare insurance (HR 1.32), and diagnosis by a specialist versus a primary care physician (HR 2.56 and 2.62 for gastroenterology and infectious disease or hepatology, respectively) (p < .01 for all). Several baseline comorbidities were associated with decreased rate of treatment, including psychiatric disorders (HR 0.87), drug use disorders (HR 0.85) and cirrhosis (HR 0.42) (p < .01 for all). These findings highlight existing HCV treatment inequities, particularly among older patients and those with psychiatric disorders, substance use disorders or chronic comorbidities. Targeted efforts to increase treatment uptake in these populations could mitigate a considerable future burden of HCV-related morbidity, mortality and healthcare costs.

BACKGROUND: Many health plans have outreach programs aimed at appropriately screening, evaluating, and treating women experiencing fragility fractures; however, few programs exist for men. OBJECTIVE: The objective of this study was to develop, implement, and evaluate an osteoporosis outreach program for men with a recent fragility fracture and their physicians. RESEARCH DESIGN AND SUBJECTS: A total of 10,934 male patients enrolled in a Medicare Advantage with Prescription Drug Plan with a recent fragility fracture were randomized to a program or control group. Patients and their physicians received letters followed by phone calls on osteoporosis and the importance of screening and treatment. The evaluation compared bone mineral density (BMD) test utilization and osteoporosis medication treatment (OPT) among patients who received the outreach versus no outreach at 12 months. The effect of the program was estimated through univariate and multivariable logistic regressions. RESULTS: The program had a significant impact on BMD evaluation and OPT initiation. At 12 months, 10.7% of participants and 4.9% of nonparticipants received a BMD evaluation. The odds ratio (OR) (95% confidence interval) was 2.31 (1.94, 2.76), and the number needed to outreach to receive a BMD test was 18. OPT was initiated in 4.0% of participants and 2.5% of nonparticipants. The OR (95% confidence interval) of receiving OPT was 1.60 (1.24, 2.07), and the number needed to outreach was 69. Adjusted ORs were similar in magnitude and significance. CONCLUSION: The program was highly effective by more than doubling the rate of BMD evaluation; however, more intensive interventions may yield an even higher screening rate.

Aim: This study assessed the clinical impact and cost-effectiveness of switching from tenofovir disoproxil fumarate (TDF) to either tenofovir alafenamide (TAF) or entecavir (ETV) in a Greek chronic hepatitis B (CHB) population. Patients & methods: A Markov model from the perspective of a third-party payer in Greece quantified the health and economic benefits of switching from TDF to either TAF or ETV over a lifetime horizon. Results: Over a lifetime, patients who switch from TDF to TAF versus patients who switch from TDF to ETV had an overall lower incidence of compensated cirrhosis (0.4% lower), decompensated cirrhosis (0.04% lower) and hepatocellular carcinoma (0.25% lower). Chronic kidney disease and end-stage renal disease were also lower in patients who switch to TAF; major osteoporotic fractures were similar for both groups. While total costs were higher for switching from TDF to TAF versus TDF to ETV due to the higher cost of TAF, switching from TDF to TAF versus ETV was cost effective with an incremental cost-effectiveness ratio of 17,113 per quality-adjusted life year. Conclusion: Switching from TDF to TAF in patients living with CHB is a cost effective strategy to reduce adverse liver disease outcomes, while improving bone- and renal-related safety outcomes.

BACKGROUND: In 2015, Spain launched a national eradication strategy for hepatitis C virus (HCV), resulting in the highest treatment rate in Europe and substantial reductions in HCV prevalence. However, to achieve the goal of HCV elimination, it is necessary to scale-up the diagnosis, treatment, and management of HCV infection. OBJECTIVE: Our aim was to assess the prevalence, incidence, and cost effectiveness of scaling-up compared with status quo scenarios. METHODS: A compartmental dynamic transmission model was developed comprising of a cascade of care and a liver progression module. Cost and quality-of-life inputs were sourced from the literature. Key outcomes were the prevalence and incidence of HCV and the incremental cost per quality-adjusted life-year (QALY) and per life-year (LY). Outcomes for a hypothetical elimination strategy were compared with the status quo. RESULTS: The base-case analysis found that scaling-up testing and treatment reduced both the prevalence and incidence of HCV over time, resulting in incremental costs per QALY and LY of 13,291 and 12,285 respectively, compared with the status quo. The main drivers of the cost-effectiveness results included cost of diagnosis, cost of treatment, proportion of people who are unaware, percentage of population who inject drugs, and calibration parameters related to HCV infection prevalence. CONCLUSIONS: This analysis demonstrated that scaling-up testing and treatment with direct-acting antivirals may be an efficient strategy for reducing the incidence and prevalence of HCV and may help achieve HCV elimination goals in Spain.
RESUMEN
BACKGROUND: Despite the success of current treatments, many chronic hepatitis B (CHB) patients still live with low-level viremia [LLV] resulting in liver disease progression. This study evaluated the long-term health and economic impact of switching to tenofovir alafenamide (TAF) from entecavir (ETV) in Saudi Arabia (SA) in chronic hepatitis B (CHB) LLV patients. METHODS: A hybrid decision tree Markov state-transition model was developed to simulate a cohort of patients with CHB LLV treated with ETV and switched to TAF over a lifetime horizon in SA. While on treatment, patients either achieved complete virologic response (CVR) or maintained LLV. CVR patients experienced slower progression to advanced liver disease stages as compared to LLV patients. Demographic data, transition probabilities, treatment efficacy, health state costs, and utilities were sourced from published literature. Treatment costs were sourced from publicly available databases. RESULTS: Base case analysis found that over a lifetime horizon, switching to TAF versus remaining on ETV increased the proportion of patients achieving CVR (76% versus 14%, respectively). Switching to TAF versus remaining on ETV resulted in a reduction in cases of compensated cirrhosis (-52%), decompensated cirrhosis (-5%), hepatocellular carcinoma (-22%), liver transplants (-12%), and a 37% reduction in liver-related deaths. Switching to TAF was cost-effective with an incremental cost-effectiveness ratio of $57,222, assuming a willingness-to-pay threshold of three times gross national income per capita [$65,790/QALY]. CONCLUSIONS: This model found that switching to TAF versus remaining on ETV in SA CHB LLV patients substantially reduced long-term CHB-related morbidity and mortality and was a cost-effective treatment strategy.

OBJECTIVES: This study investigates the utilization of work absence benefits among United States (US) employees diagnosed with COVID-19, examining frequency, duration, cost, and types of work loss benefits used. METHODS: This retrospective analysis of the Workpartners Research Reference Database (RRDb) included employees eligible for short- and long-term disability (STD and LTD employer-sponsored benefits, respectively), and other paid work absence benefits from 2018 to 2022. Workpartners RRDb includes over 3.5 million employees from over 500 self-insured employers across the US. Employees were identified by codes from adjudicated medical and disability claims for COVID-19 (2020-2022) and influenza, as well as prescription claims for COVID-19 treatments. Associated payments were quantified for each absence reason. RESULTS: Approximately 1 million employees were eligible for employer-sponsored paid leave benefits between January 2018 and December 2022. The mean age was 37 years (22% >50 years), and 49.4% were females. COVID-19 was the 2nd most common reason for an STD claim (6.9% of all STD claims) and 13th for an LTD claim (1.7% of all LTD claims) from 2020-2022. The mean duration for COVID-19 STD claims was 24 days (N = 3,731, mean claim=$3,477) versus 10 days for influenza (N = 283, mean claim=$1,721). The mean duration for an LTD claim for COVID-19 was 153 days (N = 11, mean claim=$19,254). Only 21.5% of employees with STD claims in the COVID-19 cohort had prior COVID-19-associated medical or pharmacy claims; over half (range 53%-61%) had documented high risk factors for severe COVID-19. CONCLUSION: COVID-19 and influenza have the potential to cause work loss in otherwise healthy employees. In this analysis, COVID-19 was the second most frequent reason for an STD claim at the start of the pandemic and remained high (ranked 5th) in 2022. These results highlight the impact of COVID-19 on work loss beyond the acute phase. Comprehensively evaluating work loss implications may help employers prioritize strategies, such as vaccinations and timely treatments, to mitigate the impact of COVID-19 on employees and their companies.
COVID-19 results in short- and long-term symptoms that may affect employees' ability to work. Short- and long-term disability (STD and LTD, respectively), other work absences, and medical and pharmacy claims from the Workpartners Research Reference Database were analyzed for US adult (≥18 years) employees. COVID-19 claims were identified using the Center for Disease Control and Prevention recommended International Classification of Diseases codes during the analysis from 2020 to 2022. During 2020 to 2022, COVID-19 ranked as the second most frequent reason for STD claims and 13th most frequent among LTD claims. Influenza ranked 58th overall with no LTD claims (20182022). The average COVID-19 STD claim lasted 24 days and cost employers $3,477 per claim, and LTD claims averaged 153 days, costing $19,254. Only 21.5% of employees with STD claims in the COVID-19 cohort had prior COVID-19-associated medical or pharmacy claims, and over half (range 53%61%) had a documented high-risk factor for severe COVID-19. Our results highlight the ongoing and substantial impact of COVID-19 on work absence benefit utilization beyond the acute phase. This analysis demonstrates the need for employers and researchers to review all available medical, pharmacy, and disability claims to assess the acute and long-term impact of COVID-19 on employees and prioritize mitigation strategies to reduce the burden of the virus to their employees.

BACKGROUND: Long COVID has become a central public health concern. This study characterized the effectiveness of BNT162b2 BA.4/5 bivalent COVID-19 vaccine (bivalent) against long COVID symptoms. METHODS: Symptomatic US adult outpatients testing positive for SARS-CoV-2 were recruited between 2 March and 18 May 2023. Symptoms were assessed longitudinally using a CDC-based symptom questionnaire at Week 4, Month 3, and Month 6 following infection. The odds ratio (OR) of long COVID between vaccination groups was assessed by using mixed-effects logistic models, adjusting for multiple covariates. RESULTS: At Week 4, among 505 participants, 260 (51%) were vaccinated with bivalent and 245 (49%) were unvaccinated. Mean age was 46.3 years, 70.7% were female, 25.1% had ≥1 comorbidity, 43.0% prior infection, 23.0% reported Nirmatrelvir/Ritonavir use. At Month 6, the bivalent cohort had 41% lower risk of long COVID with ≥3 symptoms (OR: 0.59, 95% CI, 0.36-0.96, p = 0.034) and 37% lower risk of ≥2 symptoms (OR: 0.63, 95% CI, 0.41-0.96, p = 0.030). The bivalent cohort reported fewer and less durable symptoms throughout the six-month follow-up, driven by neurologic and general symptoms, especially fatigue. CONCLUSIONS: Compared with unvaccinated participants, participants vaccinated with the bivalent were associated with approximately 40% lower risk of long COVID and less symptom burden over the six-month study duration.
RESUMEN
OBJECTIVE: Describe the economic burden of COVID-19 on employers and employees in the United States (US). METHODS: A targeted literature review was conducted to evaluate the impact of COVID-19 on US-based employers and employees in terms of healthcare resource utilization (HCRU), medical costs, and costs associated with work-loss. Searches were conducted in MEDLINE, Embase, and EconLit using a combination of disease terms, populations, and outcomes to identify articles published from January 2021 to November 4, 2022. As data from the employer perspective were lacking, additional literature related to influenza were included to contextualize the impact of COVID-19, as it shifts into an endemic state, within the existing respiratory illness landscape. RESULTS: A total of 41 articles were included in the literature review. Employer and employee perspectives were not well represented in the literature, and very few articles overlapped on any given outcome. HCRU, costs, and work impairment vary by community transmission levels, industry type, population demographics, telework ability, mitigation implementation measures, and company policies. Work-loss among COVID-19 cases were higher among the unvaccinated and in the week following diagnosis and for some, these continued for 6 months. HCRU is increased in those with COVID-19 and COVID-19-related HCRU can also continue for 6 months. CONCLUSIONS: COVID-19 continues to be a considerable burden to employers. The majority of COVID-19 cases impact working age adults. HCRU is mainly driven by outpatient visits, while direct costs are driven by hospitalization. Productivity loss is higher for unvaccinated individuals. An increased focus to support mitigation measures may minimize hospitalizations and work-loss. A data-driven approach to implementation of workplace policies, targeted communications, and access to timely and appropriate therapies for prevention and treatment may reduce health-related work-loss and associated cost burden.
In January 2020, the US government declared COVID-19 a public health emergency. This lasted until May 2023. To fight this health emergency, the US government provided free testing, vaccination, and treatment. Although the US government has declared the emergency over, COVID-19 continues to infect people. For people with private health insurance, costs associated with COVID-19 patient healthcare have now been transferred from the government to employers. In this study, we collected information from published scientific articles about the costs of COVID-19 for employers and workers in the US. We found that people who were not vaccinated against COVID-19 required more medical care and cost more than people who were vaccinated. In some cases, this trend lasted for as long as 6 months. This was mostly because of workers missing work, not working effectively while sick, and needing to be hospitalized. People who could work from home, whose companies had policies to prevent infections, and who took steps to avoid getting infected needed less medical care and missed work less often. This information may be used to help develop policies, communications, and guidance to prevent COVID-19 and limit its impact on employers and workers.

OBJECTIVES: Direct-acting antivirals (DAAs) for chronic hepatitis C virus (HCV) lead to cure in more than 95% of recipients; however, payers may limit access to these lifesaving drugs due to high initial cost. Here, the cost-effectiveness of treating HCV with DAAs vs no treatment over a lifetime horizon is evaluated from the perspective of Kaiser Permanente Southern California (KPSC). STUDY DESIGN: A hybrid decision-tree Markov model. METHODS: The model simulated the health and economic outcomes for a real cohort of patients with HCV treated with either ledipasvir-sofosbuvir or sofosbuvir-velpatasvir between November 1, 2014, and October 31, 2019, at KPSC. Patients entered the model at different stages of liver disease and received either active treatment with DAAs or no treatment. Patients who did not achieve sustained virological response experienced disease progression; those who achieved sustained virological response experienced either significantly slower or no disease progression depending on the stage of fibrosis at model start. Demographics, treatment experience, genotype, baseline fibrosis stage, treatment rates, and treatment efficacy were sourced from KPSC real-world data. Costs and utilities were sourced from published literature. RESULTS: A total of 7255 patients with a mean age of 59 years were treated during the study period. Over a lifetime horizon, DAAs resulted in significant reduction in advanced liver disease events and a total cost savings of $1 billion compared with no treatment based on a hybrid decision-tree Markov state-transition model. Cost savings were achieved after only 3 years. DAA intervention dominated no treatment on a per-patient and cohort basis. CONCLUSIONS: DAA treatment at KPSC is predicted to significantly reduce HCV-related morbidity and mortality, providing an anticipated return on investment in drug costs after 3 years of treatment.

COVID-19 infection adversely impacts patients' wellbeing and daily lives. This survey-based study examined differences in patient-reported COVID-19 symptoms, Health-Related Quality of Life (HRQoL) and Work Productivity and Activity Impairment (WPAI) among groups of patients defined based on age and symptom-based long COVID status. Symptomatic, COVID-19-positive US outpatients were recruited from 31 January-30 April 2022. Outcomes were collected via validated instruments at pre-COVID, Day 3, Week 1, Week 4, Month 3 and Month 6 following infection, with changes assessed from pre-COVID and between groups, adjusting for covariates. EQ-5D-5L HRQoL and WPAI scores declined in all groups, especially during the first week. Long COVID patients reported significantly higher symptoms burden and larger drops in HRQoL and WPAI scores than patients without long COVID. Their HRQoL and WPAI scores did not return to levels comparable to pre-COVID through Month 6, except for absenteeism. Patients without long COVID generally recovered between Week 4 and Month 3. Older (>50) and younger adults generally reported comparable symptoms burden and drops in HRQoL and WPAI scores. During the first week of infection, COVID-19-related health issues caused loss of 14 to 26 work hours across the groups. These data further knowledge regarding the differential impacts of COVID-19 on clinically relevant patient groups.
RESUMEN
AIMS: To identify and synthesize evidence regarding how coronavirus disease 2019 (COVID-19) interventions, including vaccines and outpatient treatments, have impacted healthcare resource use (HCRU) and costs in the United States (US) during the Omicron era. MATERIALS AND METHODS: A systematic literature review (SLR) was performed to identify articles published between 1 January 2021 and 10 March 2023 that assessed the impact of vaccination and outpatient treatment on costs and HCRU outcomes associated with COVID-19. Screening was performed by two independent researchers using predefined inclusion/exclusion criteria. RESULTS: Fifty-eight unique studies were included in the SLR, of which all reported HCRU outcomes, and one reported costs. Overall, there was a significant reduction in the risk of COVID-19-related hospitalization for patients who received an original monovalent primary series vaccine plus booster dose vs. no vaccination. Moreover, receipt of a booster vaccine was associated with a lower risk of hospitalization vs. primary series vaccination. Evidence also indicated a significantly reduced risk of hospitalizations among recipients of nirmatrelvir/ritonavir (NMV/r), remdesivir, sotrovimab, and molnupiravir compared to non-recipients. Treated and/or vaccinated patients also experienced reductions in intensive care unit (ICU) admissions, length of stay, and emergency department (ED)/urgent care clinic encounters. LIMITATIONS: The identified studies may not represent unique patient populations as many utilized the same regional/national data sources. Synthesis of the evidence was also limited by differences in populations, outcome definitions, and varying duration of follow-up across studies. Additionally, significant gaps, including HCRU associated with long COVID and various high-risk populations and cost data, were observed. CONCLUSIONS: Despite evidence gaps, findings from the SLR highlight the significant positive impact that vaccination and outpatient treatment have had on HCRU in the US, including periods of Omicron predominance. Continued research is needed to inform clinical and policy decision-making in the US as COVID-19 continues to evolve as an endemic disease.

Evidence on the impact of COVID-19 vaccination on symptoms, Health-Related Quality of Life (HRQoL) and Work Productivity and Activity Impairment (WPAI) is scarce. We analyzed associations between bivalent BA.4/5 BNT162b2 (BNT162b2) and these patient-reported outcomes (PROs). Symptomatic US adults testing positive for SARS-CoV-2 were recruited between 2 March and 18 May 2023 (CT.gov NCT05160636). PROs were assessed using four questionnaires measuring symptoms, HRQoL and WPAI (a CDC-based symptom survey, PROMIS Fatigue, EQ-5D-5L, WPAI-GH), from pre-COVID to Week 4 following infection. Multivariable analysis using mixed models for repeated measures was conducted, adjusting for several covariates. The study included 643 participants: 316 vaccinated with BNT162b2 and 327 unvaccinated/not up-to-date. Mean (SD) age was 46.5 years (15.9), 71.2% were female, 44.2% reported prior infection, 25.7% had ≥1 comorbidity. The BNT162b2 cohort reported fewer acute symptoms through Week 4, especially systemic and respiratory symptoms. All PROs were adversely affected, especially at Week 1; however, at that time point, the BNT162b2 cohort reported better work performance, driven by less absenteeism, and fewer work hours lost. No significant differences were observed for HRQoL COVID-19 negatively impacted patient outcomes. Compared with unvaccinated/not up-to-date participants, those vaccinated with bivalent BA.4/5 BNT162b2 reported fewer and less persistent symptoms and improved work performance.
RESUMEN
PURPOSE: The efficacy comparison of osteoporosis treatments can be hindered by the absence of head-to-head trials; instead, network meta-analyses (NMAs) have been used to determine comparative effectiveness. This study was the first to investigate the impact of time point-specific NMAs of osteoporosis treatments on variability in treatments' onset of action caused by their different mechanisms of actions and trial designs. METHODS: A systematic literature review was conducted to identify randomized controlled trials (RCTs) of treatments for postmenopausal women with osteoporosis, including romosozumab (ROMO), teriparatide (TPTD), abaloparatide (ABL), alendronate (ALN), risedronate (RIS), ibandronate (IB), zoledronic acid/zoledronate (ZOL), denosumab (DEN), and raloxifene (RLX), on at least 1 fracture or bone mineral density (BMD) outcome. Of 100 RCTs identified in 5 databases, 27 RCTs were included for NMAs of new vertebral, nonvertebral, and hip fracture outcomes at 12, 24, and 36 months, and 47 RCTs were included for NMAs of BMD outcomes at lumbar spine, total hip, and femoral neck to compare the relative efficacy of osteoporosis treatments. Quality of included studies was assessed using the Cochrane Risk of Bias tool. FINDINGS: For vertebral fractures, TPTD (83.63%), ABL (69.11%), and ROMO/ALN (78.70%) had the highest probability to be the most effective treatment at 12, 24, and 36 months, respectively. ROMO/ALN had the highest probability (54.4%, 64.69%, and 90.29%, respectively) to be the most effective treatment for nonvertebral fractures at 12, 24, and 36 months. For hip fractures, ROMO/ALN (46.31%), ABL (61.1%), and DEN (55.21%) had the highest probability to be the most effective treatment at 12, 24, and 36 months, respectively. ROMO had the highest probability (76.06%, 44.19%, and 51.78%, respectively) to be the most effective treatment for BMD outcomes at lumbar spine, total hip, and femoral neck. IMPLICATIONS: The importance of indirectly comparing available osteoporosis treatments using time point-specific NMAs was confirmed because indirect comparison results differed substantially across time points.

BACKGROUND: Direct-acting antivirals (DAAs) have been a breakthrough therapeutic innovation in the treatment of chronic hepatitis C virus (HCV) with significantly improved efficacy, safety, and tolerability. OBJECTIVE: To evaluate the cost-effectiveness of treating patients with HCV with DAAs compared with pre-DAAs or no treatment over a lifetime horizon from the perspective of the US Veterans Affairs (VA) health care system. METHODS: A hybrid decision-tree and Markov model simulated the health outcomes of a cohort of 142,147 patients with HCV with an average age of 63 years. Demographic data, treatment rates and distribution, treatment efficacy by subpopulation, and health state costs were sourced from VA data. Treatment costs and utility values were sourced from publicly available databases and prior publications for older regimens. RESULTS: Over a lifetime horizon, the use of DAAs results in a significant reduction in advanced liver disease events compared with pre-DAA and no treatment. Total cost savings of $7 and $9 billion over a lifetime horizon (50 years) were predicted for patients who received DAA treatments compared with patients treated with pre-DAA treatments and those who were untreated, respectively. Cost savings were achieved quickly after treatment, with DAAs being inexpensive when compared with both the pre-DAA and untreated scenarios within 5 years. The DAA intervention dominated (ie, more effective and less costly) for both the pre-DAA and untreated strategies on both a per-patient and cohort basis. CONCLUSIONS: The use of DAA-based treatments in patients with HCV in the VA system significantly reduced long-term HCV-related morbidity and mortality, while providing cost savings within only 5 years of treatment.

BACKGROUND AND OBJECTIVES: Calcimimetic drugs used to treat secondary hyperparathyroidism are being considered for inclusion in the Medicare ESRD Prospective Payment System bundle after an evaluation period. Understanding of utilization patterns of calcimimetics across dialysis facilities may help align financial incentives with clinical objectives. Our study's purpose was to describe the distribution of cinacalcet prescription across United States hemodialysis facilities and to explore factors that may influence cinacalcet utilization. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We used monthly cross-sectional data from the Dialysis Outcomes and Practice Patterns Study in 2014 to characterize the distribution of cinacalcet prescription across 203 United States hemodialysis facilities (10,521 patients). On the basis of associations with parathyroid hormone levels from patient-level analyses, we used linear mixed-effects regressions to estimate the associations between three facility-level exposures (black race, <65 years old, and having ≥3 years on dialysis [vintage]) and the prevalence of cinacalcet prescription, adjusting for facility- and patient-level potential confounders. RESULTS: The mean percentage of patients in each facility with cinacalcet prescription was 23% in June 2014 (median, 22%; interquartile range, 13%-30%). Adjusted for facility-level and nonexposure patient-level variables, the difference in prevalence of cinacalcet prescription between facilities with the highest and lowest quartiles of percentage of black patients was 7.8% (95% confidence interval [95% CI], 0.8% to 14.8%; P for trend =0.03). The adjusted prevalence difference was 7.3% for the percentage of patients aged <65 years (95% CI, -0.1% to 14.7%; P for trend =0.06) and 11.9% for the percentage of patients with ≥3 years of dialysis (95% CI, 2.4% to 21.4%; P for trend =0.02). These associations changed appreciably, becoming much weaker or even reversing, after further adjusting for the patient-level exposure variables. CONCLUSIONS: Facilities treating more patients who are black, under age 65 years, and having dialysis vintage ≥3 years have higher average levels of cinacalcet prescription. However, these differences were strongly attenuated after accounting for the unbalanced distributions of these patient case-mix variables.

PURPOSE: To describe treatment patterns and outcomes in wet-overactive bladder (OAB) patients treated with anticholinergics. METHODS: This study was a retrospective claims analysis linked to a one-time patient survey of members of a regional medical group located in California. Participants met the following criteria: received anticholinergic therapy between January 2008 and May 2012, based on pharmacy claims; had a diagnosis of OAB; and reported having ≥1 urinary incontinence (UI) episode per day at the time of the survey. Outcomes included the number of anticholinergics cycled through from treatment initiation until the end of follow-up (May 31, 2013); frequency of UI episodes; and patient requests for additional help for their OAB symptoms. RESULTS: A total of 620 patients were enrolled into the study. During the follow-up period, patients cycled through 1 to 6 unique anticholinergics; 65 % of the study population used only 1 anticholinergic, while 35 % used ≥2 anticholinergics. Patients reported experiencing an average of 3.5 UI episodes per day (3.6, 3.3, and 3.4 episodes for 1, 2, and ≥3 anticholinergics used, respectively), and over 80 % of patients requested additional help for their OAB symptoms, irrespective of how many anticholinergics were attempted. CONCLUSION: UI symptom burden and adherence to therapy did not change as patients attempted more anticholinergic therapies. These results suggest that for patients who remain incontinent after attempting an anticholinergic, cycling on additional anticholinergics may not provide any additional benefit, resulting in sub-optimal care.

BACKGROUND: Overactive bladder (OAB) is a common medical condition with significant economic and humanistic burden. Inadequately managed OAB may exacerbate or result in comorbidities such as depression, falls, and urinary tract infections, which can further increase the burden to the health care system. Anticholinergics are often prescribed for management of OAB with urinary incontinence ("wet" OAB). However, research has shown that patient adherence and persistence to anticholinergic therapy is poor, with approximately 80% of patients ultimately failing their first prescribed anticholinergic medication within the first year. While there has been a fair amount of research on the economic burden of OAB, the real-world impact of initiating anticholinergic therapy in patients with wet OAB has not been well studied. OBJECTIVE: To compare falls/fractures, anxiety/depression, health care resource utilization, and health care costs between a cohort of patients with wet OAB who initiated anticholinergic therapy and a matched cohort of patients without OAB. METHODS: This study was a retrospective medical and pharmacy claims analysis. Cases were members of a primary care-based, multispecialty physician medical group located in California. Cases were eligible for inclusion if they were prescribed anticholinergic therapy between January 2008 and May 2012 based on pharmacy claims, had a diagnosis of OAB, and reported having ≥ 1 urinary incontinence episode per day. Wet OAB cases were matched to non-OAB controls in a 1:3 ratio based on sex, age, and observation time. Medical and pharmacy claims data were used to analyze patient comorbidities, as well as track health care resource utilization (HRU) and direct payer costs. RESULTS: After initiating anticholinergic therapy, wet OAB patients had a 46% higher adjusted risk of experiencing falls/fractures (P < 0.001) and a 33% higher adjusted risk of experiencing depression/anxiety (P = 0.022) than non-OAB patients. Wet OAB was significantly associated with increased HRU rates of hospital admissions, outpatient visits, prescriptions filled, and diagnostic tests performed. After adjustment for covariates, total health care cost was 33% higher for wet OAB patients than non-OAB patients, resulting in an increased cost of $1,746 per member per year. CONCLUSIONS: The findings of this research suggest OAB patients who initiate anticholinergic therapy and still experience incontinence are at a greater risk for comorbidities such as falls/fractures and depression/anxiety, and use significantly more health care resources, than patients without OAB. Programs to improve patient monitoring and referrals, the appropriate use of alternative treatments within guidelines, and adherence to evidence-based practice parameters may improve clinical outcomes and decrease HRU for these patients.
