Adherence and out-of-pocket costs among Medicare beneficiaries who are prescribed oral targeted therapies for advanced prostate cancer.
The authors investigated coping and material measures of the financial hardship of abiraterone and enzalutamide among patients with advanced prostate cancer with Medicare Part D coverage. They found substantial variations in the adherence rate and out-of-pocket payments, with sociodemographic patient and regional factors found to be associated with both aspects.

Treatment, outcomes, and adherence to medication regimens among dual Medicare-Medicaid-eligible adults with myocardial infarction.
The purpose of the study was to examine the association of dual-eligible status with clinical outcomes and adherence to medication regimens among older adults after MI. The investigators found that compared with Medicare-only patients, older adults with dual Medicare-Medicaid eligibility presenting with MI had superior rates of medication adherence but higher rates of postdischarge readmission and adverse cardiovascular outcomes.

Trends in antihypertensive medication discontinuation and low adherence among Medicare beneficiaries initiating treatment from 2007 to 2012.
The authors analyzed a 5% sample of Medicare beneficiaries initiating antihypertensive medication between 2007 and 2012 to assess whether reductions occurred in discontinuation and low adherence. They found that low adherence decreased and was more common among racial/ethnic minorities, beneficiaries with Medicaid buy-in, and those with polypharmacy, and was less common among females, beneficiaries initiating antihypertensive medication with multiple classes or a 90-day prescription fill, with dementia, a history of stroke, and those who reached the Medicare Part D coverage gap in the previous year. They concluded that although low adherence has decreased, rates of discontinuation and low adherence remain high.

Effect of clinical and attitudinal characteristics on obtaining comprehensive medication reviews.
The researchers sought to quantify the association between attitudinal and clinical factors with intention and predict future behavior to obtain a comprehensive medication reviews (CMR) among Medicare Part D beneficiaries. They found that worrying about medications doing more harm than good, number of pharmacies where participants obtained their medications from, number of medications, and number of medical conditions predicted intention to obtain a CMR.

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.
