Examining systemic steroid use in older inflammatory bowel disease patients using hurdle models: a cohort study.
In order to evaluate the relationship between patient characteristics and the frequency and duration of incident steroid use, the researchers applied a 2-part hurdle model to Medicare data. Their study identified differences in predictors of frequency and duration of medication use and suggests the utility of two-part models to examine drug utilization patterns.

Association of patient enrollment in Medicare Part D with outcomes after acute myocardial infarction.
The researchers investigated whether enrollment versus nonenrollment in Medicare's prescription drug plan (Part D) is associated with better outcomes after acute myocardial infarction (AMI). They found that only half of Medicare-insured patients with AMI were enrolled in Part D by hospital discharge, and their 30-day and 1-year adjusted outcomes did not differ substantially from nonenrollees.

Changes in medication management after a diagnosis of cancer among Medicare beneficiaries with diabetes.
The researchers sought to determine whether a new cancer diagnosis is associated with changes in medication adherence among Medicare beneficiaries with diabetes. They concluded that cancer diagnosis among patients with diabetes reduced adherence with evidence-based medications, particularly if patients’ life expectancy was short.

Medicare coverage of anesthesia services during screening colonoscopies for patients at low risk of sedation-related complications.
The authors examined the costs and potential benefit of the Medicare rule change that waived patient cost sharing for anesthesia services during screening colonoscopies. Their results cast doubt on the value associated with Medicare coverage of anesthesia services during screening colonoscopies for patients at low risk of sedation-related complications. They recommended that payers create payment bundles for endoscopy procedures that include anesthesia services in a fixed fee.

Coverage for high-cost specialty drugs for rheumatoid arthritis in Medicare Part D.
The aim of this study was to conduct the first systematic, national investigation of how Part D plans cover biologic disease-modifying anti-rheumatic drugs (DMARDs) and to determine patients’ financial burden under current cost-sharing structures. It found that all Medicare Part D drug plans cover at least 1 biologic DMARD, access is highly controlled through prior authorization requirements, and beneficiaries face significant cost sharing.

Stimulating comprehensive medication reviews among Medicare Part D beneficiaries.
The authors assessed the impact of a patient engagement intervention utilizing the Medication User Self-Evaluation (MUSE) tool on the completion percentage of comprehensive medication reviews (CMRs) among Medicare Part D beneficiaries. They found that the estimated odds of having a CMR among those who received the MUSE intervention were 2 times that of their counterparts. They concluded that Part D plans could use the MUSE to engage targeted beneficiaries in using pharmacist-provided MTM services.

Effect of hospitalization on inappropriate prescribing in elderly Medicare beneficiaries.
This study sought to determine whether acute hospitalization is associated with a change in potentially inappropriate medication (PIM) use and whether use varies across geographic region. It found that despite intervention studies demonstrating up to 80% reduction in PIM use during acute hospitalization, a significant increase in PIM use was observed in a naturalistic setting in Medicare beneficiaries with acute myocardial acute myocardial infarction.

Patient cost sharing and receipt of erythropoiesis-stimulating agents through Medicare part D.
This study examined use of erythropoiesis-stimulating agents (ESAs) to manage anemia in patients with myelodysplastic syndromes (MDS). It found that few patients with MDS received ESAs through Part D. OOP payments required under Part D were substantially higher than under Part B. Cost sharing, as reflected by low-income subsidy receipt, likely affected decisions to prescribe ESAs outside of the physician office.

Regional variation in use of a new class of antidiabetic medication among Medicare beneficiaries: the case of incretin mimetics.
After incretin mimetic medications (IMs), a new class of diabetes drugs, were introduced in 2005, researchers examining their use as well as their cost implications for Medicare Part D between 2005 and 2010 found substantial geographic variation existing in their use that was not accounted for by sociodemographic and health status factors. Also, IM use was associated with substantially greater costs for Part D plans and beneficiaries.

Use of intelligent assignment to Medicare Part D plans for people with schizophrenia could produce substantial savings.
The investigators simulated Medicare Part D savings from replacing random assignment with an "intelligent assignment" algorithm that would assign beneficiaries to the least expensive plan in 2010 based on their drug usage in the previous year. They found that intelligent assignment could have saved about $150 million for Medicare and beneficiaries with schizophrenia combined in 2010.

Use of statins by Medicare beneficiaries post myocardial infarction: poor physician quality or patient-centered care?
This study assessed whether patterns of statin use by Medicare beneficiaries post-discharge may be due to a mix of high-quality and low-quality physicians. It found that the distribution of statin fill rates across physicians was normal, with no clear distinctions in physician quality. Physicians, especially cardiologists, with relatively younger and healthier patient populations had higher rates of statin use.

Changes in drug coverage generosity and untreated serious mental illness: transitioning from Medicaid to Medicare Part D.
This study examined the effects of transitioning to Part D coverage among disabled dual enrollees with schizophrenia or a bipolar disorder, comparing enrollees in states with strict Medicaid cap policies with enrollees in states without caps. It found significant reductions in the number of people with a serious mental illness who were not treated owing to the transition to Part D from strictly capped Medicaid coverage.

Treating age-related macular degeneration: comparing the use of two drugs among Medicare and Veterans Affairs populations.
The researchers examined the diffusion of new biologics ranibizumab and bevacizumab, both for the treatment of macular degeneration but differing in price, in fee-for-service Medicare and Veterans Affairs (VA) systems during 2005-11, in part to assess the impact that differing financial incentives had on prescribing. Their analysis indicated that there are opportunities in both the VA and Medicare to adopt more value-conscious treatment patterns and that multiple mechanisms exist to influence utilization.

Specialty drug spending trends among Medicare and Medicare Advantage enrollees, 2007-11.
The authors analyzed trends in specialty drug spending among Medicare beneficiaries ages sixty-five and older using 2007-11 pharmacy claims data. They found that annual specialty drug spending per beneficiary who used specialty drugs increased considerably during the study period, but specialty drugs accounted for less than ten percent of total drug spending per beneficiary. Additionally, in 2011, cost-sharing reductions under the Affordable Care Act significantly reduced specialty drug users' out-of-pocket burden, which decreased 26 percent from 2010.

A simple change to the Medicare Part D low-income subsidy program could save $5 billion.
The authors used an intelligent reassignment algorithm and 2008-09 Medicare Part D drug use and spending data to match enrollees to available Part D plans according to their medication needs. They found that such a reassignment approach, compared to the current approach, could have saved the federal government over $5 billion in 2009.

The effect of supplemental medical and prescription drug coverage on health care spending for Medicare beneficiaries with cancer.
The researchers examined whether patients with newly diagnosed cancer respond differently to supplemental coverage than the general Medicare population. They concluded that Medicare beneficiaries with cancer are less responsive to the presence and type of supplemental insurance than are beneficiaries without cancer. They recommended that policymakers consider welfare effects associated with coverage restrictions.
