991-P: Use of a Mobile Diabetes Self-Management Application Is Associated with Increased Blood Glucose Monitoring Frequency and Improved Glycemic Control

Introduction and Objectives: While recommended blood glucose monitoring (BGM) frequency varies by therapy and individual circumstances, many people with type 2 diabetes (T2D) may not follow suggested monitoring guidelines. Given recent advancements in blood glucose monitoring technology, we studied the impact of connecting a BG meter to a mobile diabetes self-management app (mySugr®) on testing frequency and glycemic control. Methods: We performed a retrospective analysis of 103,400 mySugr app users in the United States with self-reported T2D who were enrolled between January, 2018 and November, 2023 and calculated the change in BG testing frequency and mean BG per 30-day period in the 180 days following glucometer connection to mySugr to the 30-day period prior to connection. We also analyzed the impact of BG logging frequency on the change in glycemic control. Results: Following enrollment in the app, users increased the frequency of BG testing from a baseline of 19.87 logs (95% CI 19.61-20.15) in the 30-day period prior to mySugr connection to 52.38 BG logs (52.02-52.74) in days 0-30 following connection and 32.57 logs (32.27-32.86) at 150-180 days. Mean BG was 175.87 mg/dL (175.43-176.36) at baseline and 143.99 mg/dL (143.62 - 144.38) at 180 days following connection to mySugr. Users who logged greater than 30 logs between 150 and 180 days after registration had a greater reduction of mean BG (-20.44 mg/dL -19.70 - -21.22) than those with 30 or fewer logs (-18.35 mg/dL -17.78 - -18.95). Conclusion: Following glucometer connection to the mySugr app, users recorded significantly more BG logs up to 180 days following connection. Use of the mySugr app was associated with a significant reduction in mean BG, and users who recorded 30 logs/30 days achieved a greater reduction in mean BG vs. those who recorded = 30 logs/30 days.
