D14A - The Combined Use of rtCGM and a Digital Health Tool Positively Impacts ADCES7 Self-Care Behaviors

Key Takeaways of Your Research: 1. rtCGM use coupled with a digital therapeutic can help individuals with T2D (who are not prescribed insulin) improve ADCES7 Self-Care Behaviors. 2. Engagement with the digital health solution was greater in the continuous use cohort. 3. Clinicians should consider how rtCGM wear time influences self-care behaviors to coach and treat individuals with diabetes.

Background/Purpose: Real-time CGM has been helpful in optimizing glucose management for people with diabetes. Previously, it was felt that the greatest benefit was for those with T1D or T2D treated with bolus insulin. Recent studies suggest that non-intensive insulin users also benefit from rtCGM. Since insulin dosing is not a factor with them, the rtCGM data must be influencing diabetes-related behaviors. Research Hypothesis and/or Research Questions and Specific

Aims: We reviewed data from individuals with T2D enrolled in a program that provided a Dexcom G6 system and Welldoc’s BlueStar platform. We previously reported that participants achieved improvements in glycemic control. In this study, we aimed to understand how engaging with the combined solution influenced ADCES7 Self-Care Behaviors. Methods/Methodology: Participant engagement with the digital health solution was examined. The data was de-identified for analysis. Cohort 1 (n=37) used rtCGM continuously for 24 weeks. Cohort 2 (n=55) used rtCGM intermittently. Counts of specific feature use of the digital health solution that support ADCES7 Self-Care Behaviors, such as food, medication tracking, activity, sleep, BP, and weight were tabulated.

Results: 56% of rtCGM users were male. 44% were 40-54 years old. 36% were 55-64 years old. The mean baseline A1C was 9.5%. Average engagement frequency per user per week is shown below. Cohort 1 interacted with the digital health solution at a higher weekly engagement frequency than that of Cohort 2. In the first 12 weeks, Cohort 1 had a significantly higher total average weekly engagement than Cohort 2 (p=0.00005). Conclusions (Impact on Diabetes Care and Education): rtCGM use coupled with a digital health solution can help individuals with T2D (who are not prescribed insulin) improve ADCES-7 self-care behaviors. Engagement with the digital health solution was greater in the continuous use cohort. These data suggest that clinicians should consider how rtCGM wear time influences self-care behaviors to coach and treat individuals with diabetes. Source of Funding for this Research: None.
