120-LB: Sharing Dexcom G6 Data and Glycemic Outcome—A Comparative Analysis

  • Endocrinology, Diabetes and Metabolism

Introduction: In recent years the use of Continuous Glucose Monitoring (CGM) has significantly increased. The Dexcom G6 CGM sends real-time glucose readings automatically to a smart device. The Dexcom Clarity app allows users to share up-to-date glucose data with providers, enabling remote monitoring of patients' glycemic control. Although studies have shown better glucose control in patients who use CGM, it is unexplored if glucose metrics are further improved in those who share CGM data with providers. In this study, we compared glycemic outcomes in patients who share their data with their providers via the Dexcom G6 sensor to those who do not.

Method: We conducted a single-center cross-sectional study in a community hospital with patients who use Dexcom G6 CGM. Data was obtained from Dexcom Clarity for Healthcare Professionals, an online platform for clinicians to review patient trends. The following data was collected for each patient: date of last upload, data sharing status, average glucose, standard deviation, glucose management indicator, glucose range, sensor usage, and coefficient of variation. Two-tailed unpaired Student's t-tests were used to analyze CGM metrics based on data sharing status. Significance was defined as a p-value < 0.05.

Results: 123 (61.19%) out of 201 participants shared data with their provider. Participants with sharing data ‘on’ were significantly younger (49±15 years,) and had increased sensor usage (90±21%) compared to those with sharing off. Participants who shared data also spent more time in range (57±24 %), 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.

Conclusion: The data-sharing feature on Dexcom G6 was utilized more by younger people and was associated with a higher percentage of time in range. Using the data-sharing feature of the Dexcom G6 could lead to clinically meaningful improvement in glycemic control.
