Prescriber continuity and medication availability in older adults with cardiometabolic conditions.
Researchers examined whether the number of prescribers of essential medications was associated with the availability of medications, a surrogate for adherence, to manage diabetes, hypertension or dyslipidemia. They found that the number of prescribers was not significantly associated with availability of oral diabetes agents but having more prescribers is associated with increased medication availability in older Medicare beneficiaries with dyslipidemia or hypertension.

Adherence to tyrosine kinase inhibitors among Medicare Part D beneficiaries with chronic myeloid leukemia.
The authors of this study identified 836 patients with chronic myeloid leukemia (CML) with Medicare Part D insurance coverage who were new tyrosine kinase inhibitors (TKI) users and examined treatment nonadherence. They indicted that the current population-based study found a significantly higher rate of nonadherence among heavily subsidized patients with substantially lower out-of-pocket costs, which suggested that future research is needed to help lower the nonadherence rate among these individuals.

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.

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.
