Impact Evaluation of the Therapeutic Initiative's Type 2 Diabetes in Older Adults Portrait and Therapeutics Letter

The goal of this randomized trial is to learn if educational materials and personalized prescribing portraits change how clinicians in British Columbia (BC), Canada treat older adults with type 2 diabetes (T2DM). The main question the investigators aim to answer is: • Did a personalized prescribing portrait and therapeutics letter lead to a change in the number of older adults prescribed sulfonylureas or insulin when they have glycated hemoglobin (A1C) levels below 7%, compared to usual care. Study participants are nurse practitioners and family physicians actively practicing in BC, Canada. Participants registered on the project website, Portrait Online, to receive their digital prescribing portraits. Participants were randomized to either receive educational materials in the Early Group or in the Delayed Group. Using administrative health data, the prescribing of those in the Early Group will be compared to those in the Delayed Group to see if the materials influenced their prescribing.
