Arms Assigned Interventions
Experimental: Diabetes Medication Choice decision aid
Patients in this arm will discuss diabetes medication for glucose control with the help of a decision aid that covers five commonly prescribed anti-hyperglycemic medications.
Behavioral: Diabetes Medication Choice decision aid
The decision aid covers five commonly prescribed anti-hyperglycemic medications and their attributes.
Usual Care
Patients and clinicians in this arm will discuss anti-hyperglycemic agents in their usual manner.
Behavioral: Usual Care
Patients and clinicians in this arm will discuss anti-hyperglycemic agents in their usual manner.
