SUPREME-DM (Diabetes Mellitis) Treatment Study

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.
