The Effect of Dose Escalation on the Cost-Effectiveness of Etanercept and Adalimumab with Methotrexate Among Patients with Moderate to Severe Rheumatoid Arthritis.

BACKGROUND: Patients with moderate to severe rheumatoid arthritis (RA) occasionally increase their doses of tumor necrosis factor (TNF) inhibitors, especially the monoclonal antibody origin drugs such as adalimumab and infliximab, after inadequate response to the initial dose. Previous studies have evaluated the cost-effectiveness of various sequences of treatment for RA in the United States but have not considered the effect of dose escalation. OBJECTIVE: To assess the cost-effectiveness of etanercept and adalimumab by incorporating the effect of dose escalation in moderate to severe RA patients. METHODS: We adapted the open-source Innovation and Value Initiative - Rheumatoid Arthritis model, version 1.0 to separately simulate the magnitude and time to dose escalation among RA patients taking adalimumab plus methotrexate or etanercept plus methotrexate from a societal perspective and lifetime horizon. An important assumption in the model was that dose escalation would increase treatment costs through its effect on the number of doses but would have no effect on effectiveness. We estimated the dose escalation parameters using the IBM MarketScan Commercial and Medicare Supplemental Databases. We fit competing parametric survival models to model time to dose escalation and used model diagnostics to compare the fit of the competing models. We measured the magnitude of dose escalation as the percentage increase in the number of doses conditional on dose escalation. Finally, we used the parameterized model to simulate treatment sequences beginning with a TNF inhibitor (adalimumab, etanercept) followed by nonbiologic treatment. RESULTS: In baseline models without dose escalation, the incremental cost per quality-adjusted life-year of the etanercept treatment sequence relative to the adalimumab treatment sequence was $85,593. Incorporating dose escalation increased treatment costs for each sequence, but costs increased more with adalimumab, lowering the incremental cost-effectiveness ratio to $9,001. At willingness-to-pay levels of $100,000, the etanercept sequence was more cost-effective compared with the adalimumab sequence, with probability 0.55 and 0.85 in models with and without dose escalation, respectively. CONCLUSIONS: Dose escalation has important effects on cost-effectiveness and should be considered when comparing biologic medications for the treatment of RA.

Contemporary treatment utilization among women diagnosed with symptomatic uterine fibroids in the United States.

BACKGROUND: This study evaluated treatment patterns among women diagnosed with symptomatic uterine fibroids (UF) in the United States. Data were retrospectively extracted from the IBM Watson Health MarketScan® Commercial Claims and Encounters and Medicaid Multi-State databases. METHODS: Women aged 18-64 years with ≥1 medical claim with a UF diagnosis (primary position, or secondary position plus ≥1 associated symptom) from January 2010 to June 2015 (Commercial) and January 2009 to December 2014 (Medicaid) were eligible; the first UF claim during these time periods was designated the index date. Data collected 12 months pre- and 12 and 60 months post-diagnosis included clinical/demographic characteristics, pharmacologic/surgical treatments, and surgical complications. Prevalence (2015) and cumulative incidence (Commercial, 2010-2015; Medicaid, 2009-2015) of symptomatic UF were estimated. RESULTS: 225,737 (Commercial) and 19,062 (Medicaid) women had a minimum of 12 months post-index continuous enrollment and were eligible for study. Symptomatic UF prevalence and cumulative incidence were: 0.57, 1.23% (Commercial) and 0.46, 0.64% (Medicaid). Initial treatments within 12 months post-diagnosis were surgical (Commercial, 36.7%; Medicaid, 28.7%), pharmacologic (31.7%; 53.0%), or none (31.6%; 18.3%). Pharmacologic treatments were most commonly non-steroidal anti-inflammatory drugs and oral contraceptives; hysterectomy was the most common surgical treatment. Of procedures of abdominal hysterectomy, abdominal myomectomy, uterine artery embolization, and ablation in the first 12 months post-index, 14.9% (Commercial) and 24.9% (Medicaid) resulted in a treatment-associated complication. Abdominal hysterectomy had the highest complication rates (Commercial, 18.5%; Medicaid, 31.0%). CONCLUSIONS: Off-label use of pharmacologic therapies and hysterectomy for treatment of symptomatic UF suggests a need for indicated non-invasive treatments for symptomatic UF.

Real-World Treatment Patterns Of Cyclosporine Ophthalmic Emulsion And Lifitegrast Ophthalmic Solution Among Patients With Dry Eye.

PURPOSE: To assess adherence, non-persistence, discontinuation, and switching of topical cyclosporine ophthalmic emulsion 0.05% (CYC) and lifitegrast ophthalmic solution 5% (LIF) use in the real world among patients with dry eye disease (DED). DESIGN: Retrospective insurance claims study. METHODS: Adult patients with DED and ≥1 prescription claim for CYC or LIF (first claim = index date) in the IBM® MarketScan® databases from July 2016 to February 2018 were identified. Eligible patients had continuous medical and pharmacy benefits in the 12 months pre- and post-index periods, and no prior use of the index medication. The proportion of days covered (PDC), adherence, non-persistence, discontinuation, and switching were examined over the 12-month post-index period. RESULTS: This study included 6537 CYC and 3235 LIF patients. The adherence rate was 5.9% for CYC and 9.7% for LIF; the median PDC was 0.3 for both cohorts. Overall, 70.8% of CYC and 64.4% of LIF patients discontinued treatment with median days to discontinuation of 89 and 29, respectively. Non-persistence was 7.1% for CYC and 6.8% for LIF (median days to discontinuation: 89 and 105). In addition, 5.0% switched from CYC to LIF, and 9.6% switched from LIF to CYC over the post-index period. CONCLUSION: Over 60% of DED patients discontinued treatment within 12 months of initiation; the median time to discontinuation was 3 months for CYC and 1 month for LIF. Although this analysis did not capture the reasons why patients discontinued treatment, the results demonstrate there likely exists a significant unmet need amongst DED patients.

Meningococcal-group B (MenB) vaccine series completion and adherence to dosing schedule in the United States: A retrospective analysis by vaccine and payer type.

BACKGROUND: Two MenB vaccines with different dosing schedules are approved in the US: MenB-4C (2 doses) and MenB-FHbp (2-3 doses). Both vaccines were licensed on the basis of immunogenicity demonstrated after vaccine series completion. We evaluated vaccination completion and adherence to dosing schedules. METHODS: This retrospective analysis used data from MarketScan Commercial Claims and Encounters Database (Commercial) January 1, 2015 - February 28, 2018 and Multi-State Medicaid Database (Medicaid) January 1, 2015 - December 31, 2017 to examine vaccine series completion and adherence to dosing schedule in individuals who initiated a MenB series at ages 16-23 years. Vaccine series completion and dose schedule adherence were assessed during a 15-month follow-up period after the first dose. Completion was defined as individual receipt of the recommended number of doses, with current recommendations applied retroactively to allow individuals who initiated the MenB-FHbp series to be complete with either the 2- or the 3-dose schedule. RESULTS: The study population comprised 65,205 commercially-insured individuals (36,118 initiated MenB-4C; 29,087 initiated MenB-FHbp) and 13,535 Medicaid-covered individuals (10,153 initiated MenB-4C; 3382 initiated MenB-FHbp). In Commercial, 63% of individuals who initiated MenB-4C and 52% of individuals who initiated MenB-FHbp completed vaccination within 15 months; dosing schedule adherence was 62% for MenB-4C initiators and 18% for MenB-FHbp initiators. In Medicaid, 15-month completion rates for MenB-4C and MenB-FHbp initiators were 49% and 31%, respectively, with corresponding dosing schedule adherence of 48% and 8%. Among individuals who completed the series, median time to completion was 68 days for MenB-4C versus 258 days for MenB-FHbp in Commercial and 88 days for MenB-4C versus 309 days for MenB-FHbp in Medicaid. CONCLUSION: During the study period, MenB vaccine series completion was suboptimal. However, completion was significantly higher for MenB-4C, with notably shorter time to completion. This may reflect the flexible dosing schedule of MenB-4C.

Does Lifestyle Exercise After a Cardiac Event Improve Metabolic Syndrome Profile in Older Adults?

BACKGROUND: Exercise is a common recommendation to reduce the risk factors of metabolic syndrome, yet there are limited data on the influence of lifestyle exercise after cardiac events on metabolic syndrome factors. OBJECTIVE: The purpose of this study was to determine whether lifestyle exercise improves metabolic syndrome profile in older adults after a cardiac event. METHODS: Participants were from a post-cardiac-event lifestyle exercise study. Five metabolic syndrome factors were assessed: waist circumference, triglycerides, high-density lipids, glucose, and systolic and diastolic blood pressure. Objective measures of exercise were obtained from heart rate monitors over a year. Logistic regression was used to determine whether participants who engaged in the minimum recommendation of 130 hours of exercise or greater during the 12-month period improved their metabolic syndrome profile by improving at least 1 metabolic syndrome factor. RESULTS: In the sample of 116 participants (74% men; average age, 67.5 years), 43% exercised at the recommended amount (≥130 h/y) and 28% (n = 33) improved their metabolic syndrome profile. After controlling for confounding factors of age, gender, race, diabetes, functional ability, and employment, subjects who exercised at least 130 hours a year were 3.6 times more likely to improve at least 1 metabolic syndrome factor (95% confidence interval, 1.24-10.49). Of the 28% who improved their metabolic syndrome profile, 72% increased their high-density lipoprotein and 60.6% reduced their waist circumference and glucose. CONCLUSIONS: After a cardiac event, older patients who engage in lifestyle exercise at the recommended amount have improvement in their metabolic syndrome profile.

All-cause and diabetes-related healthcare costs among US adults with type 2 diabetes initiating exenatide once weekly or insulin glargine.

AIMS: To compare healthcare utilization and costs between patients with type 2 diabetes (T2D) treated with exenatide (Bydureon) once weekly (EQW) and patients treated with insulin glargine (IG). MATERIALS AND METHODS: Using the MarketScan Commercial and Medicare Supplemental databases, we conducted a retrospective cohort study of adult US patients with claim with a diagnosis of T2D, initiating EQW or IG from February 1, 2012 to June 30, 2014 (first claim = index date). All-cause and diabetes-related utilization and costs were measured during the 12 months after the index date. EQW patients were matched 1:1 to IG patients, using propensity scores. Logistic and ordinary least-squares regression models were fit to model differences between the matched cohorts. RESULTS: There were 7749 EQW patients matched to 7749 IG patients. EQW patients had significantly (P < .05) lower odds of all-cause inpatient (IP) admissions (odds ratio = 0.737 [95% confidence interval, 0.661, 0.822]), diabetes-related IP admissions (0.720 [95% confidence interval, 0.635, 0.815]) and diabetes-related IP admissions or emergency room visits (0.778 [95% confidence interval, 0.713, 0.847]). EQW patients had significantly (P < .05) lower all-cause (cost difference = -113 USD [95% confidence interval, -120 USD, -106 USD]) and diabetes-related (-806 USD [95% confidence interval, -871 USD, -746 USD]) medical costs, and had significantly (P < .05) higher all-cause total costs (ie, medical plus pharmacy) (3228 USD [95% confidence interval, 3110 USD, 3367 USD]), diabetes-related total costs (1951 USD [95% confidence interval, 1873 USD, 2036 USD]), all-cause pharmacy costs (2792 USD [95% confidence interval, 2700 USD, 2928 USD]) and diabetes-related pharmacy costs (1923 USD [95% confidence interval, 1890 USD, 1957 USD]) than those of IG patients. CONCLUSIONS: Among adults with T2D, EQW initiators had lower odds of IP admission and lower medical costs in the 12 months after initiation than IG initiators. Higher total costs in EQW patients were driven by greater pharmacy costs.

Impact of a Comprehensive Workplace Hand Hygiene Program on Employer Health Care Insurance Claims and Costs, Absenteeism, and Employee Perceptions and Practices.

OBJECTIVE: The aim of this study was to determine the efficacy of a multimodal hand hygiene intervention program in reducing health care insurance claims for hygiene preventable infections (eg, cold and influenza), absenteeism, and subjective impact on employees. METHODS: A 13.5-month prospective, randomized cluster controlled trial was executed with alcohol-based hand sanitizer in strategic workplace locations and personal use (intervention group) and brief hand hygiene education (both groups). Four years of retrospective data were collected for all participants. RESULTS: Hygiene-preventable health care claims were significantly reduced in the intervention group by over 20% (P < 0.05). Absenteeism was positively impacted overall for the intervention group. Employee survey data showed significant improvements in hand hygiene behavior and perception of company concern for employee well-being. CONCLUSION: Providing a comprehensive, targeted, yet simple to execute hand hygiene program significantly reduced the incidence of health care claims and increased employee workplace satisfaction.

Dietary intake of calcium and magnesium and the metabolic syndrome in the National Health and Nutrition Examination (NHANES) 2001-2010 data.

Higher dietary intakes of Mg and Ca, individually, have been associated with a decreased risk for the metabolic syndrome (MetSyn). Experimental studies suggest that a higher intra-cellular ratio of Ca:Mg, which may be induced by a diet high in Ca and low in Mg, may lead to hypertension and insulin resistance. However, no previous epidemiological studies have examined the effects of the combined intake of Mg and Ca on MetSyn. Thus, we evaluated the association between dietary intakes of Ca and Mg (using 24-h recalls), independently and in combination, and MetSyn in the National Health and Nutrition Examination Study 2001-2010 data, which included 9148 adults (4549 men and 4599 women), with complete information on relevant nutrient, demographic, anthropometric and biomarker variables. We found an inverse association between the highest (>355 mg/d) v. the lowest (<197 mg/d) quartile of Mg and MetSyn (OR 0.70; 95% CI 0.57, 0.86). Women who met the RDA for both Mg (310-320 mg/d) and Ca (1000-1200 mg/d) had the greatest reduced odds of MetSyn (OR 0.59; 95% CI 0.45, 0.76). In men, meeting the RDA for Mg (400-420 mg/d) and Ca (1000-1200 mg/d), individually or in combination, was not associated with MetSyn; however, men with intakes in the highest quartile for Mg (≥ 386 mg/d) and Ca (≥ 1224 mg/d) had a lower odds of MetSyn (OR 0.74; 95% CI 0.59, 0.93). Our results suggest that women who meet the RDA for Mg and Ca have a reduced odds of MetSyn but men may require Ca levels higher than the RDA to be protected against MetSyn.
