RESUMEN
BACKGROUND: While phosphodiesterase type-5 inhibitors (PDE5Is) are highly effective for the treatment of erectile dysfunction (ED) and well tolerated, updated data on prescription patterns have been limited in real-world settings. AIM: To describe men in the United States who are prescribed PDE5Is for ED treatment and to evaluate patterns of initiation, switching, and treatment overlap. METHODS: This retrospective claims study used MarketScan Commercial and Medicare Supplement Databases from January 1, 2010, to December 31, 2015, to identify initial PDE5I claims (index date) for sildenafil, tadalafil, and/or vardenafil. Adults aged ≥18 years with ED were identified between July 1, 2010, and December 31, 2014, allowing for a 6-month preindex and 12-month follow-up period from the index date. OUTCOMES: Outcomes included patient demographics and treatment-related patterns after treatment initiation. RESULTS: A total of 106,206 identified patients met all inclusion criteria. Of these, 51,694, 40,193, and 14,319 had initial claims for sildenafil, tadalafil, and vardenafil, respectively. Mean age was 50.35 years, and comorbidities included dyslipidemia (44.17%), hypertension (43.09%), diabetes (15.32%), and depression (10.61%). More patients (48.67%) initiated on sildenafil than tadalafil (37.85%) or vardenafil (13.48%). Rate of switching was lower in the 60 days after the end of day supply of the initial prescription in the sildenafil cohort (2.71%) compared with the tadalafil (2.81%) and vardenafil (3.88%) cohorts (P < .001 for sildenafil vs tadalafil or vardenafil). Treatment overlap was lower in the sildenafil cohort (0.35%) than in the tadalafil (0.75%) and vardenafil (0.62%) groups (P < .001 for sildenafil vs tadalafil or vardenafil). CLINICAL IMPLICATIONS: These findings provide insight into updated patterns of PDE5I prescriptions in the United States and may aid in clinical decision-making. STRENGTHS & LIMITATIONS: Strengths include the large sample size, long data coverage period, and the real-world nature of the study. Limitations include the retrospective study design, use of data collected with a primary focus of claims, and lack of further details regarding reasons that drive switching. Actual rates of ED and impact on prescription patterns may be underestimated because the claims database only captured patients electing to visit a health-care provider. CONCLUSION: Among men with ED in the United States, rates of switching and treatment overlap were low for all PDE5Is but were found to be the lowest for sildenafil compared with tadalafil and vardenafil.

OBJECTIVES: Prior studies of erectile dysfunction (ED) tend to narrowly focus on relationships with specific comorbidities, rather than evaluating a more comprehensive array of risk factors and assessing naturalistic patterns among them. This study identifies natural clusters of male characteristics from a general population sample per country, quantifies ED dynamics in these profiles and compares profiles across the US, Italy, Brazil and China samples. METHODS: National Health and Wellness Survey 2015 and 2016 patient-reported data on men aged 40-70 years (USA n = 15,652; Italy n = 2,521; Brazil n = 2,822; China n = 5,553) were analysed. Hierarchical agglomerative clustering identified clusters where predictors included demographics, health characteristics/behaviours, ED risk factors and provider visits in the past 6 months. Multinomial logistic regression assessed the independent utility of variables in predicting cluster membership, compared with the healthiest control cluster per country. RESULTS: Different natural clusters were found across countries, with four clusters for the USA, Italy and China and three clusters for Brazil. Age, income, employment, health behaviours and ED risk factors predicted different cluster membership across countries. In the USA, Italy and Brazil, younger clusters were predicted by ED, unhealthy behaviours and ED risk factors. Unique cluster profiles were identified in China, with ED and ED risk factors (aside from hypertension) not predicting cluster membership, while socio-demographics and health behaviours were strongly predictive. CONCLUSIONS: Natural cluster profiles revealed notable ED rates among adult males of age 40-70 in four different countries. Clusters were mainly predicted by unhealthy behaviours, ED risk factors and ED, regardless of level or presence of positive health characteristics and behaviours. This analysis identified meaningful subgroups of men with heightened ED risk factors, which can help healthcare providers to better recognise specific populations with the greatest need for intervention.

AIM: To evaluate the association of erectile dysfunction (ED) with work productivity loss, activity impairment and health-related quality of life (HRQoL) across Brazil, China, France, Germany, Italy, Spain, the UK and the US. METHODS: This cross-sectional observational study used data from adult men (40-70 years old; N = 52 697) from the 2015 and 2016 National Health and Wellness Surveys. ED assessment was based on self-reported difficulty in achieving or maintaining an erection in the past 6 months. Impairment to work and non-work activities and HRQoL were assessed for each country and compared against the US. Multivariable models tested interactions between ED status and country for each outcome. RESULTS: Overall ED prevalence was reported as 49.7%, with Italy reporting the highest rate (54.7%). Men with ED reported significantly higher absenteeism (7.1% vs 3.2%), presenteeism (22.5% vs 10.1%), overall work productivity impairment (24.8% vs 11.2%), activity impairment (28.6% vs 14.5%) and significantly lower Mental Component Summary scores (MCS; 46.7 vs 51.2), Physical Component Summary scores (PCS; 48.3 vs 53.0), and health state utilities (SF-6D: 0.693 vs 0.778; all, P < 0.001) than men with no ED. After adjusting for covariates, compared with the US, the association of ED status with overall work productivity impairment was greatest in the UK (26% higher; P < 0.05), and with MCS, PCS and SF-6D scores was greatest in China (-2.67, -1.58, and -0.043 points, respectively; all, P < 0.001). Greater ED severity was significantly associated with higher impairment to work and non-work activities and lower HRQoL, with China reporting the highest burden, compared with the US (most P < 0.05). CONCLUSION: ED poses a significant burden with respect to work productivity and HRQoL, with greater severity associated with worse outcomes. Better management and earlier detection may help reduce this burden, especially in countries reporting a strong association between ED and poor economic and health outcomes.

PURPOSE: Mechanical ventilation (MV) remains a substantial cost driver in intensive care units (ICU) in the United States (US). Evaluations of standard sedation treatments used to relieve pain and discomfort in this setting have found varying impacts on ICU length of stay. This cost analysis examines both length-of=stay costs and the total cost implications among MV patients receiving common sedative treatments (dexmedetomidine, propofol, or midazolam) in short-term sedation settings (<24 hours). METHODS: A cost-minimization model was conducted from the hospital provider perspective. Clinical outcomes were obtained from published literature and included ICU length of stay, MV duration, prescription of sedatives and pain medication, and the occurrence of adverse events. Outcomes costs were obtained from previously conducted ICU cost studies and Medicare payment fee schedules. All costs were estimated in 2018 US Dollars. RESULTS: The per patient costs associated with dexmedetomidine, propofol, and midazolam were estimated to be $21,115, $27,073, and $27,603, respectively. Dexmedetomidine was associated with a savings of $5958 per patient compared to propofol and a saving of $6487 compared to midazolam. These savings were primarily driven by a reduction in ICU length of stay and the degree of monitoring and management. CONCLUSION: Dexmedetomidine was associated with reduced costs when compared to propofol or midazolam used for short-term sedation during MV in the ICU, suggesting sedative choice can have a potential impact on overall cost per episode.
RESUMEN
OBJECTIVES: To describe opportunities for early switch (ES) from intravenous (IV) to oral (PO) antibiotics and early discharge (ED) of patients hospitalized in the Kingdom of Saudi Arabia (KSA) and the United Arab Emirates (UAE) with methicillin-resistant Staphylococcus aureus (MRSA) complicated skin and soft tissue infections (cSSTIs). METHODS: This retrospective medical chart review study enrolled physicians from 16 KSA and UAE sites to collect data for 107 MRSA cSSTI patients. RESULTS: Actual length of MRSA-active treatment was 13.3±9.3 mean days in KSA and 11.2±3.9 mean days in UAE, with a mean of 11.8±9.3 days of MRSA-targeted IV therapy in KSA and 10.7±4.3 days in UAE. 12.5% in KSA met ES criteria and potentially could have discontinued IV therapy 4.0±2.9 days sooner; 44.0% in UAE could have discontinued 6.6±3.6 days sooner. Patients were hospitalized for a mean 28.6±45.0 days in KSA and 13.1±5.9 days in UAE. 25.0% in KSA and 48.0% in UAE met ED criteria and potentially could have been discharged 6.1±8.0 days earlier in KSA and 7.9±5.0 days earlier in UAE. CONCLUSIONS: A significant proportion of patients hospitalized for MRSA cSSTI could be eligible for ES or ED opportunities, resulting in potential for reductions in IV and bed days.

BACKGROUND: Early antibiotic switch and early discharge protocols have not been widely studied in Latin America. Our objective was to describe real-world treatment patterns, resource use, and estimate opportunities for early switch from intravenous to oral antibiotics and early discharge for patients hospitalized with methicillin-resistant Staphylococcus aureus complicated skin and soft-tissue infections. MATERIALS/METHODS: This retrospective medical chart review recruited 72 physicians from Brazil to collect data from patients hospitalized with documented methicillin-resistant Staphylococcus aureus complicated skin and soft tissue infections between May 2013 and May 2015, and discharged alive by June 2015. Data collected included clinical characteristics and outcomes, hospital length of stay, methicillin-resistant Staphylococcus aureus-targeted intravenous and oral antibiotic use, and early switch and early discharge eligibility using literature-based and expert-validated criteria. RESULTS: A total of 199 patient charts were reviewed, of which 196 (98.5%) were prescribed methicillin-resistant Staphylococcus aureus -active therapy. Only four patients were switched from intravenous to oral antibiotics while hospitalized. The mean length of methicillin-resistant Staphylococcus aureus-active treatment was 14.7 (standard deviation, 10.1) days, with 14.6 (standard deviation, 10.1) total days of intravenous therapy. The mean length of hospital stay was 22.2 (standard deviation, 23.0) days. The most frequent initial methicillin-resistant Staphylococcus aureus-active therapies were intravenous vancomycin (58.2%), intravenous clindamycin (19.9%), and intravenous daptomycin (6.6%). Thirty-one patients (15.6%) were discharged with methicillin-resistant Staphylococcus aureus -active antibiotics of which 80.6% received oral antibiotics. Sixty-two patients (31.2%) met early switch criteria and potentially could have discontinued intravenous therapy 6.8 (standard deviation, 7.8) days sooner, and 65 patients (32.7%) met early discharge criteria and potentially could have been discharged 5.3 (standard deviation, 7.0) days sooner. CONCLUSIONS: Only 2% of patients were switched from intravenous to oral antibiotics in our study while almost one-third were early switch eligible. Additionally, one-third of hospitalized patients with methicillin-resistant Staphylococcus aureus complicated skin and soft tissue infections were early discharge eligible indicating opportunity for reducing intravenous therapy and days of hospital stay. These results provide insight into possible benefits of implementation of early switch/early discharge protocols in Brazil.

OBJECTIVE: To explore changes in healthcare costs among postmenopausal women in a commercial population who were prescribed conjugated estrogens for menopausal symptoms. METHODS: Using the MarketScan dataset from April 1, 2008 through September 30, 2012, postmenopausal women aged ≥45 years, who were prescribed conjugated estrogen tablets (Premarin), were identified. A comparative cohort of postmenopausal women with vasomotor symptoms without any menopause therapy was also identified. Women included were required to have continuous medical and pharmacy benefits for 6 months before and 12 months after index date, with baseline characteristics compared using chi-square and t tests. The 6 and 12-month change (difference in follow-up and baseline costs) in direct healthcare costs was calculated and a difference-in-differences model was used to compare the incremental change at 6 and 12 months in healthcare costs between the cohorts, adjusting for demographic and clinical characteristics. RESULTS: The study included 1,404 women who were prescribed conjugated estrogens, and 3,096 untreated women. Women prescribed conjugated estrogens were significantly younger (52 vs 54 years; Pâ<â0.0001) and had a lower Charlson comorbidity index score (0.29 vs 0.41; Pâ<â0.001) compared with the untreated women. After adjusting for baseline characteristics, women treated with conjugated estrogens showed a greater difference in the change in total healthcare costs (-$1,601 vs -$503; Pâ=â0.044), including inpatient stay costs (-$1,431 vs -$28; Pâ<â0.0001), between the baseline and follow-up periods compared with untreated women. CONCLUSIONS: Women who were prescribed oral conjugated estrogens had a significantly greater reduction in healthcare costs after treatment initiation compared with untreated postmenopausal women.
RESUMEN
Biopharmaceuticals (biologics) represent one of the fastest growing sectors of cancer treatment. They are recommended for treating underlying cancer and as supportive care for management of treatment side effects. Given the high costs of cancer care and the need to balance health care provision and associated budgets, patient access and value are the subject of discussion and debate in the USA and globally. As the costs of biologics are high, biosimilars offer the potential of greater choice and value, increased patient access to treatment, and the potential for improved outcomes. Value-based care aims to improve the quality of care, while containing costs. The Centers for Medicare & Medicaid Services (CMS) has developed value-based care programs as alternatives to fee-for-service reimbursement, including in oncology, that reward health care providers with incentive payments for improving the quality of care they provide. It is anticipated that CMS payments in oncology care will be increasingly tied to measured performance. This review provides an overview of value-based care models in oncology with a focus on CMS programs and discusses the contribution of biosimilars to CMS value-based care objectives. Biosimilars may provide an important tool for providers participating in value-based care initiatives, resulting in cost savings and efficiencies in the delivery of high-value care through expanded use of biologic treatment and supportive care agents during episodes of cancer care.
RESUMEN
BACKGROUND: A network meta-analysis can provide estimates of relative efficacy for treatments not directly studied in head-to-head randomized controlled trials. We estimated the relative efficacy and safety of dolutegravir (DTG) versus third agents currently recommended by guidelines, including ritonavir-boosted atazanavir (ATV/r), ritonavir-boosted darunavir (DRV/r), efavirenz (EFV), cobicistat-boosted elvitegravir (EVG/c), ritonavir-boosted lopinavir (LPV/r), raltegravir (RAL), and rilpivirine (RPV), in treatment-naive HIV-1-infected patients. METHODS: A systematic review of published literature was conducted to identify phase 3/4 randomized controlled clinical trials (up to August 2013) including at least one third agent of interest in combination with a backbone nucleoside reverse transcriptase inhibitor (NRTI) regimen. Bayesian fixed-effect network meta-analysis models adjusting for the type of nucleoside reverse transcriptase inhibitor backbone (tenofovir disoproxil fumarate/emtricitabine [TDF/FTC] or abacavir/lamivudine [ABC/3TC]) were used to evaluate week 48 efficacy (HIV-RNA suppression to <50 copies/mL and change in CD4+ cells/µL) and safety (lipid changes, adverse events, and discontinuations due to adverse events) of DTG relative to all other treatments. Sensitivity analyses assessing the impact of NRTI treatment adjustment and random-effects models were performed. RESULTS: Thirty-one studies including 17,000 patients were combined in the analysis. Adjusting for the effect of NRTI backbone, treatment with DTG resulted in significantly higher odds of virologic suppression (HIV RNA<50 copies/mL) and increase in CD4+ cells/µL versus ATV/r, DRV/r, EFV, LPV/r, and RPV. Dolutegravir had better or equivalent changes in total cholesterol, LDL, triglycerides, and lower odds of adverse events and discontinuation due to adverse events compared to all treatments. Random-effects and unadjusted models resulted in similar conclusions. CONCLUSION: Three clinical trials of DTG have demonstrated comparable or superior efficacy and safety to DRV, RAL, and EFV in HIV-1-infected treatment-naive patients. This network meta-analysis suggests DTG is also favorable or comparable to other commonly used third agents (ATV/r, LPV/r, RPV, and EVG/c).
