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.

Impact of a value-based formulary in three chronic disease cohorts.
This study assessed the impact of a value based formulary (VBF) on adherence and patient and health plan expenditures on 3 chronic disease states: diabetes, hypertension, and hyperlipidemia. The investigators measured medication expenditures from member, health plan, and member-plus-health plan (overall) perspectives and medication adherence as proportion of days covered. They conducted an exploratory analysis of medication utilization classifying medications according to whether co-payments moved up or down in the year following VBF implementation.
