Study to Test Use of a Decision Aid in a Clinical Visit to Help Patients Choose a Diabetes Medication

To conduct a cluster-randomized practical trial to evaluate the impact of our decision aid (Diabetes Medication Choice Cards) versus usual care as strategies to translate CER into practice among patients with poorly controlled diabetes in need of drug intensification (Hemoglobin Alc (HbA1c) > 7.3%). Patient outcomes including reaching glycemic control target (HbA1c less than or equal to 7.3%), medication choice and adherence, satisfaction and knowledge. From the physician perspective, we will be measuring physician adoption and satisfaction with the decision aid.

To identify, describe, and explain factors that promote or inhibit the uptake of complex interventions such as decision aids in practices participating in the trial.

To conduct an exploratory analysis of the ability of patients to adhere to the medications chosen while exploring the factors that enable or hinder the patients' ability to incorporate these medications into their routine.
