Integration of the Glucose Management Indicator (GMI) into the electronic health record through a diabetes-cardiometabolic digital health app
Health systems are increasingly integrating digital health solutions to provide personalized support to patients and timely insights to clinicians. The Allina Health system,, has partnered with Welldoc to integrate Welldoc’s FDA-cleared cardiometabolic digital app into their diabetes program. The Welldoc App syncs with continuous glucose monitoring (CGM) devices. This integration enables the system to capture a new metric, Glucose Management Indicator (GMI) to help support patients with diabetes. GMI is a calculated value based on CGM data that provides an estimate of a person's average blood sugar (A1C) over a shorter period. This is valuable because GMI can show changes in glucose levels faster than a traditional A1C test, which is helpful for both patients and clinicians. The poster outlines the GMI as a new metric for success in diabetes and key aspects of health system-health tech collaboration in diabetes.
Key Takeaways:
- New Metric for Success: Welldoc is the first to utilize GMI as a quality metric within a digital health solution. The GMI is a calculated value used to estimate A1C based on CGM data. It provides a unique value in that it can be reported in a shorter time period (10-14 days) and allows for faster observation of glucose changes. The GMI's inclusion as a quality metric in the 2025 HEDIS measures recognizes the value of CGM data in assessing diabetes management.
- The power of health system-health tech collaboration: Allina and Welldoc partnered to effectively integrate the Welldoc solution into Allina’s diabetes program, which included workflow, eHR integration and incorporating data into clinical interventions and treatment plans.
- Eye on Quality of Care: The incorporation of GMI as a quality metric is essential for maintaining high Health Plan Ratings and Star ratings for value-based care. This integration helps health systems meet their quality goals and ultimately improves care for people with diabetes.

Individuals living with type 2 diabetes were enrolled in a program that provided the Dexcom G6 system and BlueStar to understand how engagement with the combined solution influenced the Association of Diabetes Care and Education Specialists’ 7 self-care (ADCES7) behaviors. Data showed that those who continuously used real-time CGM (rtCGM) engaged with the app 13% more than those who used it intermittently. In addition, this data showed that engagement with a digital solution, coupled with continuous rtCGM use, can help individuals with T2D — even those who are not prescribed insulin — improve adherence to ADCES7 behaviors.
Real-world Digital Health Data Demonstrate the Utility of the Glycemia Risk Index (GRI) as a Composite CGM Metric
Welldoc® and Carey Business School of Johns Hopkins University (formerly CHIDS, University of Maryland) worked together to study how continuous glucose monitoring (CGM) and a digital health solution can help support better glycemic outcomes for individuals with type 1 and type 2 diabetes. A Glycemia Risk Index (GRI) metric was applied to this study to assist with the basic clinical interpretation of CGM data. GRI was calculated for each individual and classified into the five GRI zones from lowest (A: best) to highest (E: worst), with a breakdown by gender, age, and diabetes type. Our results showed that diabetes type was not a factor in GRI improvement, but, individuals whose baseline GRI started in higher zones improved GRI by at least 1 zone—supporting the use of CGM and a digital health solution in self-managing glycemia. In addition, the demographic data shows that GRI was significantly lower in females and individuals 65 years and older. The culmination of GRI and demographic data can help healthcare professionals support and manage individuals and populations with diabetes.
