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.

Does increased adherence to medications change health care financial burdens for adults with diabetes?
The aim of the present study was to investigate increased out-of-pocket drug costs and financial burdens of achieving adherence to oral antidiabetic medications and medications for prevalent comorbidities. The researchers found that the mean simulated additional out-of-pocket drug costs of achieving adherence were $310 for uninsured adults treated for diabetes. These additional drug costs would increase the percentage of uninsured adults with financial burden.

Reach and validity of an objective medication adherence measure among safety net health plan members with diabetes: a cross-sectional study.
The objective of this study was to evaluate the performance of continuous medication gap (CMG) for diverse, low-income managed care members with diabetes. It concluded that CMG demonstrated acceptable inclusiveness and validity in a diverse, low-income safety net population, comparable with its performance in studies among other insured populations.

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.

Stress, depression and medication nonadherence in diabetes: test of the exacerbating and buffering effects of family support.
The researchers tested the moderation hypotheses that the associations between stressors/depressive symptoms and nonadherence would be stronger in the context of more obstructive family behaviors (exacerbating hypothesis) and weaker in the context of more supportive family behaviors (buffering hypothesis). They found that stressors and nonadherence were only associated at higher levels of obstructive family behaviors. Similarly, depressive symptoms and nonadherence were only associated at higher levels of obstructive family behaviors.
