The Patient Protection and Affordable Care Act creates a host of new rules for all entities in health care, but especially for health insurers. The statute itself, and the regulations to which it gives rise, will change the nature of the insurance business, particularly in the small-group and individual markets. Regulatory proceedings and some litigation are likely to determine the final shape of the new rules. At the same time, collaborative efforts among insurers, providers, and regulators could lead to innovations that increase access to coverage while also reducing costs. ©2010 Project HOPE - The People-to-People Health Foundation, Inc.

Background: Adherence to medications that are prescribed after myocardial infarction is poor. Eliminating out-of-pocket costs may increase adherence and improve outcomes. Methods: We enrolled patients discharged after myocardial infarction and randomly assigned their insurance-plan sponsors to full prescription coverage (1494 plan sponsors with 2845 patients) or usual prescription coverage (1486 plan sponsors with 3010 patients) for all statins, beta-blockers, angiotensin-converting-enzyme inhibitors, or angiotensin- receptor blockers. The primary outcome was the first major vascular event or revascularization. Secondary outcomes were rates of medication adherence, total major vascular events or revascularization, the first major vascular event, and health expenditures. Results: Rates of adherence ranged from 35.9 to 49.0% in the usual-coverage group and were 4 to 6 percentage points higher in the full-coverage group (P<0.001 for all comparisons). There was no significant between-group difference in the primary outcome (17.6 per 100 person-years in the full-coverage group vs. 18.8 in the usualcoverage group; hazard ratio, 0.93; 95% confidence interval [CI], 0.82 to 1.04; P = 0.21). The rates of total major vascular events or revascularization were significantly reduced in the full-coverage group (21.5 vs. 23.3; hazard ratio, 0.89; 95% CI, 0.90 to 0.99; P = 0.03), as was the rate of the first major vascular event (11.0 vs. 12.8; hazard ratio, 0.86; 95% CI, 0.74 to 0.99; P = 0.03). The elimination of copayments did not increase total spending ($66,008 for the full-coverage group and $71,778 for the usual-coverage group; relative spending, 0.89; 95% CI, 0.50 to 1.56; P = 0.68). Patient costs were reduced for drugs and other services (relative spending, 0.74; 95% CI, 0.68 to 0.80; P<0.001). Conclusions: The elimination of copayments for drugs prescribed after myocardial infarction did not significantly reduce rates of the trial's primary outcome. Enhanced prescription coverage improved medication adherence and rates of first major vascular events and decreased patient spending without increasing overall health costs.

In this article we highlight the important role that medication therapy can play in preventing disease and controlling costs. Focusing on coronary artery disease, we demonstrate that prevention, with the appropriate use of generic medications, appears far more cost-effective than previously documented, and it may even save on costs. For example, an earlier study estimated that reducing blood pressure to widely established clinical guidelines in nondiabetic patients cost an estimated $52,983 per quality-adjusted life-year if a brand-name drug was used. However, we estimate that the cost is just $7,753 per quality-adjusted life-year at generic medication prices. As the nation attempts to find strategies to improve population health without adding to the unsustainably high cost of care, policy makers should focus on ensuring that patients have access to essential generic medications. © 2011 Project HOPE-The People-to-People Health Foundation, Inc.

BACKGROUND: Classifying medication adherence is important for efficiently targeting adherence improvement interventions. The purpose of this study was to evaluate the use of a novel method, group-based trajectory models, for classifying patients by their long-term adherence. RESEARCH DESIGN: We identified patients who initiated a statin between June 1, 2006 and May 30, 2007 in prescription claims from CVS Caremark and evaluated adherence over the subsequent 15 months. We compared several adherence summary measures, including proportion of days covered (PDC) and trajectory models with 2-6 groups, with the observed adherence pattern, defined by monthly indicators of full adherence (defined as having ≥24 d covered of 30). We also compared the accuracy of adherence prediction based on patient characteristics when adherence was defined by either a trajectory model or PDC. RESULTS: In 264,789 statin initiators, the 6-group trajectory model summarized long-term adherence best (C=0.938), whereas PDC summarized less well (C=0.881). The accuracy of adherence predictions was similar whether adherence was classified by PDC or by trajectory model. CONCLUSIONS: Trajectory models summarized adherence patterns better than traditional approaches and were similarly predicted by covariates. Group-based trajectory models may facilitate targeting of interventions and may be useful to adjust for confounding by health-seeking behavior. Copyright © 2013 by Lippincott Williams & Wilkins.

Circulation: Cardiovascular Quality and Outcomes | Year: 2013
Background - New anticoagulants may improve health outcomes in patients with atrial fibrillation, but it is unclear whether their use is cost-effective. Methods and Results - A Markov state transition was created to compare 4 therapies: dabigatran 150 mg BID, apixaban 5 mg BID, rivaroxaban 20 mg QD, and warfarin therapy. The population included those with newly diagnosed atrial fibrillation who were eligible for treatment with warfarin. Compared with warfarin, apixaban, rivaroxaban, and dabigatran, costs were $93 063, $111 465, and $140 557 per additional quality-adjusted life year gained, respectively. At a threshold of $100 000 per quality-adjusted life year, apixaban provided the greatest absolute benefit while still being cost-effective, although warfarin would be superior if apixaban was 2% less effective than expected. Although apixaban was the optimal strategy in our base case, in probabilistic sensitivity analysis, warfarin was optimal in an equal number of iterations at a cost-effectiveness threshold of $100 000 per quality-adjusted life year. Conclusions - While at a standard cost-effectiveness threshold of $100 000 per quality-adjusted life year, apixaban seems to be the optimal anticoagulation strategy; this finding is sensitive to assumptions about its efficacy and cost. In sensitivity analysis, warfarin seems to be the optimal choice in an equal number of simulations. As a result, although all the novel oral anticoagulants produce greater quality-adjusted life expectancy than warfarin, they may not represent good value for money. © 2013 American Heart Association, Inc.
