Technology-Driven Diabetes Care: Real-World Evidence from 3790 People with Diabetes on Improved Glycemic Management while Using a Mobile Diabetes App

Background: Technology-enabled diabetes self-management solutions may positively affect clinical outcomes in people with diabetes (PWD). This real-world study demonstrates improvement of glycemic metrics in individuals using a diabetes app with a family of Bluetooth® connected blood glucose (BG) meters. Methods: Aggregated anonymized BG readings extracted from the app server were analyzed from 3790 PWD divided into two groups based on when they started using the app and meter: PWD who started using the meter, installed the app, and synchronized on the same day (Group 1), and PWD who had used the meter for ≥14 days before they installed the app and performed syncing (Group 2). For Group 1, data from the first 14-days using meter and app (baseline) were compared with 14-days prior to 90- and 180-days using paired, within-subject differences. For Group 2, we additionally used data from the 14 days prior to app installation as pre-baseline. Results: In Group 1, people with type 1 diabetes (T1D) and type 2 diabetes (T2D) reduced mean BG by −7.8 and −18.3 mg/dL, respectively, improving readings in range (RIR) by +3.4 (68.6%–72.0%) and +10.6 percentage points (80.8%–91.4%), respectively, from baseline to 180 days. In Group 2, people with T1D and T2D reduced mean BG by −13.5 and −13.3 mg/dL, respectively, from pre-baseline to baseline and by −11.6 and −22.9 mg/dL from pre-baseline to 180 days. RIR improved by +5.1 (58.3%–63.4%) and +12.4 percentage points (73.9%–86.4%) in people with T1D and T2D, respectively, from pre-baseline to 180 days, with people with T1D showing the most pronounced improvement in the first 2 weeks of app usage (+7.4 percentage points, 58.3%–65.6%). All glycemic changes were statistically significant ( P < 0.01). Conclusion: Real-world data demonstrated improvements in glycemic metrics among 3790 PWDs using a mobile app with a connected glucose meter.
