Generic initiation and antidepressant therapy adherence under Medicare Part D.
This study assessed the effects of initiating antidepressant treatment with a generic versus a branded prescription (generic initiation) on adherence to antidepressant therapy for the treatment of depression. It found that starting patients with generics had benefits for antidepressant adherence by lowering out-of-pocket costs for all patients and by mitigating the effect of the Part D coverage gap faced by patients not receiving low-income subsidies.

How Medicare Part D benefit phases affect adherence with evidence-based medications following acute myocardial infarction.
The authors assessed the impact of Medicare Part D benefit phases on adherence with evidence-based medications after hospitalization for an acute myocardial infarction (AMI). They found that as the Part D doughnut hole is gradually filled in by 2020, Medicare Part D enrollees with critical diseases such as AMI who rely heavily on brand name drugs are likely to exhibit modest increases in adherence, while those reliant on generic drugs are less likely to be affected.

Integrating risk adjustment and enrollee premiums in health plan payment.
Paying health plans from two different sources such as risk-adjusted payments from a regulator and premiums charged to individual enrollees raises issues in payment design for both Medicare Advantage plans and the new State-run exchanges created by the Affordable Care Act. The primary purpose of this study is to demonstrate the versatility of least squares methods for risk adjustment in individual insurance markets with enrollee premiums.

Lenalidomide performance in the real world: patterns of use and effectiveness in a Medicare population with myelodysplastic syndromes.
The authors examined the use of lenalidomide in the Medicare population. They found that reductions in transfusion rates were overall consistent with data from clinical trials, and response rates were higher when ≥ 3 lenalidomide cycles were received.

Bariatric surgery in minority patients before and after implementation of a centers of excellence program.
This study compared rates of bariatric surgery for minority Medicare vs. non-Medicare patients before and after the 2006 implementation of a national coverage decision (NCD) restricting Medicare patients to centers of excellence for bariatric surgery. It found that the proportion of nonwhite Medicare patients receiving this procedure dropped from 27.5 percent before the NCD to 25.9 percent afterwards.

Medicare payment reform and provider entry and exit in the post-acute care market.
The researchers examined the impact of Medicare payment reform on the entry and exit of post-acute providers (home health agencies and skilled nursing facilities). They found that payment reforms reducing average and marginal payments reduced entries and increased exits from the market, with entries more likely to be affected.

Symptom burden predicts nursing home admissions among older adults.
Using a sample of community-dwelling Medicare beneficiaries in Alabama who were contacted by telephone every 6 months during an eight and a half-year study, researchers found that symptom burden is an independent risk factor for NH admission. The study suggests that symptom assessment and management may reduce NH utilization.

Standardizing Medicare payment information to support examining geographic variation in costs.
This paper describes a method for standardizing claim payments, and demonstrates the difference in actual versus standardized payments by geographic region. It found that without standardization of payments, certain areas of the country are mischaracterized as either high or low healthcare resource-consuming areas.

Effectiveness of mesh compared with nonmesh sling surgery in Medicare beneficiaries.
This study assessed the effectiveness of mesh compared to nonmesh slings in the surgical treatment of female incontinence. It found that overall rates of complications were similar for patients undergoing either mesh or nonmesh sling procedures. However, patients undergoing the nonmesh procedure were more likely to require a subsequent intervention for bladder outlet obstruction.

Form CMS-2728 data versus erythropoietin claims data: implications for quality of care studies.
The purpose of this study was to compare predialysis erythropoietin-simulating agents (ESA) care reported on Form CMS-2728 with Medicare claims for ESA treatment submitted for patients 67 years and older at initiation of dialysis with Medicare as the primary payer. It found that the agreement between Form CMS-2728 and claims data is poor and discordant results are observed when comparing the use of these data sources to predict health outcomes.

Medicare and commercial inpatient resource use: impact of hospital competition.
The authors examined the influence of hospital competition on small-area inpatient resource use by payer. Using HCUP data, they found that policies or incentives that promote or encourage competition in less competitive markets may reduce variation in resource use for both Medicare and private payers.

Patterns of erythropoiesis-stimulating agent use among Medicare beneficiaries with myelodysplastic syndromes and consistency with clinical guidelines.
The researchers used SEER registries data to assess population-based patterns of erythropoiesis-stimulating agents (ESA) use relative to treatment guidelines. They found widespread use of ESA in Medicare beneficiaries with myelodysplastic syndromes.
