The intervention arm consisted of one protocol-structured telephone call from an interventionist who was a nurse health manager (1 site), diabetes educator or diabetes educator trainee (1 site), or pharmacist (2 sites). Interventionists followed the same structured telephone interview protocol to ascertain whether the subject had started taking the new prescription. Those taking the new medication as prescribed received positive reinforcement. Those who either had not filled the prescription or were not taking the medication as directed, were asked about reasons for nonadherence and assisted in identifying and resolving barriers. The median call lasted < than 5 minutes, and up to 3 call attempts were made. Most intervention calls occurred within 2 to 6 weeks after the prescription date.

Those in the control arm received usual care.

In a pragmatic randomized trial, we randomly assigned 2,378 adults with diabetes mellitus who were recently prescribed a new class of medication for elevated glycated hemoglobin (A1c) >= 8%, blood pressure >= 140/90 mm Hg, or low-density lipoprotein cholesterol >=100 mg/dL, to receive (a) one scripted telephone call from a diabetes educator or clinical pharmacist to identify and address nonadherence to the new medication or (b) usual care. Hierarchical linear and logistic regression models were used to assess impact on (a) first medication fill within 60 days of prescription,
