TEAM CGM: Team Support to Improve Glycemic Control Using CGM in Diverse Populations


To evaluate if continuous glucose monitoring (CGM) can improve glycemic control in the primary care setting targeting individuals with poorly controlled type 2 diabetes.


  • Evaluate the effectiveness of pharmacist supported CGM in the primary care setting.
  • Evaluate CHW support beyond pharmacist + CGM.
  • Evaluate Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework.
  • Determine total cost and cost-effectiveness of CGM and the supportive components (e.g., clinical pharmacist and CHW) from the perspective of the healthcare organization.

Study Design

A Sequential, Multiple Assignment, Randomized Trial (SMART). Enrolled patients are first randomized to receive CGM with clinical pharmacist support vs. pharmacist support only. After 6 months, hemoglobin A1c is assessed. Those in both groups not meeting goals in therapy receive additional support. Besides clinical pharmacist support, patients can also receive assistance from a Community Health Worker (CHW).
