SAT106 Use Of Data Sharing Feature Of Dexcom G6 Sensor Is Associated With Improved Glycemic Control: A Comparative Analysis

Abstract

Abstract Disclosure: B. Sadek: None. Introduction: The use of Continuous Glucose Monitoring (CGM) sensors has significantly increased in part due to the seamless integration with smartphones. The Dexcom G6 CGM automatically sends real-time glucose readings to a compatible smart device. Moreover, the Dexcom Clarity app provides analytic tools and allows users to continuously share glucose data with their healthcare professionals, enabling remote monitoring of patients' glycemic control. Although multiple studies have shown better glucose control in patients who use CGM systems, what remains unexplored is if glucose metrics are further improved in those who share CGM data with healthcare providers. In this study, we compared glycemic outcomes among patients who use the sharing feature of the Dexcom G6 sensor to share their data with their healthcare providers to those who do not. Method: We conducted a single-center cross-sectional study in a community hospital with patients who use the Dexcom G6 CGM (n=201). Data was obtained from Dexcom Clarity for Healthcare Professionals, an online platform for clinicians to review patients' glucose patterns and statistics through interactive reports. The following data was collected for each patient: date of the last upload, data sharing status, average glucose, standard deviation, glucose management indicator (GMI) (%), glucose ranges (categorized as very high, high, in range, low, very low), sensor usage, and coefficient of variation (%). Two-tailed unpaired Student's t-tests were used to analyze the CGM metrics based on data sharing status. Significance was defined as a p-value less than 0.05. Results: 123 (61.19%) of the study participants shared data with healthcare providers. Participants with sharing data 'on' were significantly younger (49±15 years, p-value = 0.0007) and had increased sensor usage (90±21%, p-value = 0.0012), compared to those with sharing off. Participants who shared data spent more time in range (57±24 %, p-value = 0.0435), indicating a higher percentage of readings with glucose levels in a healthy range (70-180 mg/dL). Lastly, average glucose was lower in participants who shared data, although not statistically significant (179 ±44 mg/dL, p=0.08). Conclusion: The data-sharing feature on Dexcom G6 was utilized more frequently by younger people and was associated with a higher percentage of sensor usage. In addition, using the data-sharing feature of the Dexcom G6 could lead to a clinically meaningful improvement in glycemic control. Presentation: Saturday, June 17, 2023
