CGM data can be summarized and reviewed retrospectively. CLARITY provides options for reviewing data from Dexcom CGM systems, including on-demand reports and five types of notifications (disabled by default) that are auto-generated and pushed to users’ smart devices. We examined user engagement with CLARITY reports and notifications, and their associations with estimated glucose value (EGV)-based parameters. EGVs uploaded in October 2019 from a convenience sample of 2,637 U.S.-based users of Dexcom CGM systems were analyzed. Group 1 did not access CLARITY, Group 2 accessed on-demand reports but not auto-generated notifications, and Group 3 enabled all types of auto-generated notifications throughout that month. For each group, EGV-based parameters including time in range (TIR) and the % of users meeting consensus-based goals were calculated. Unpaired t-tests were used to compare time in ranges; two-proportion z-tests were used to compare % of users meeting goals. Auto-generated CLARITY notifications were associated with more TIR and less time spent in hyperglycemia, with clinically and statistically significant differences in favor of Group 3 vs. Group 1. A significantly higher proportion of users in Group 3 than in Group 1 met consensus goals for TIR (Table). Push notifications related to CGM data may contribute to patient engagement and/or to beneficial therapeutic choices.
