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.

Health care system-level factors associated with performance on Medicare STAR adherence metrics in a large, integrated delivery system.
The researchers examined the association of Medicare STAR adherence metrics with system-wide factors for patients with diabetes. They found that the strongest predictor of achieving STAR-defined medication adherence for patients with diabetes was a greater days’ supply of medications. Other important factors were use of a mail order pharmacy, lower copayments and lower annual individual out-of-pocket maximums.

Medicare Star excludes diabetes patients with poor CVD risk factor control.
This study is designed to improve understanding of novel CMS quality measures (adherence to antihypertensives, antihyperlipidemics, and oral antihyperglycemics) by assessing the proportion of Medicare patients with diabetes who are excluded from the Medicare Star medication adherence metrics due to early nonadherence and insulin use. Medicare’s STAR measures are used to evaluate the performance of Medicare Advantage plans.
