Cost-related medication non-adherence among U.S. adults with diabetes.
The purpose of this study is to examine factors that affect cost-related medication non-adherence (CRN), defined as taking medication less than as prescribed because of cost, among adults with diabetes and to determine their relative contribution in explaining CRN. Among other results, the study found that Insulin users had 1.24 times higher risk of CRN compared to those not on insulin.

Effect of out-of-pocket cost on medication initiation, adherence, and persistence among patients with type 2 diabetes: the Diabetes Study of Northern California (DISTANCE).
This study estimated the effect of out-of-pocket (OOP) cost on nonadherence to classes of cardiometabolic medications among patients with diabetes. Primary nonadherence (never dispensed) increased monotonically with OOP cost after adjusting for demographics, neighborhood socioeconomic status, Medicare, medical financial assistance, OOP maximum, deductibles, mail order pharmacy incentive and use, drug type, generic or brand, day's supply, and comorbidity index.

Associations between Medicare Part D and out-of-pocket spending, HIV viral load, adherence, and ADAP use in dual eligibles with HIV.
This study estimated the effect of Medicare part D on self-reported out-of-pocket prescription drug spending, AIDS Drug Assistance Program (ADAP) use, antiretroviral adherence, and HIV viral load (VL) suppression among dual eligibles with HIV. It concluded that part D was associated with increased out-of-pocket spending, although the increased spending did not seem to compromise antiretroviral therapy adherence or HIV VL suppression.
