1923-P: High Satisfaction with Continuous Glucose Monitoring in Prediabetes: A Feasibility Study in Primary Care

Key Points

This study aimed to evaluate the acceptability of continuous glucose monitors (CGMs) among participants with prediabetes.
Identified adult participants with prediabetes based on HbA1c (5.7-6.4%) and ICD-10 codes.
Participants used the Dexcom Stelo CGM for 15 days, supported by remote onboarding.
Primary outcome measured CGM acceptability with the CGM Satisfaction Scale (CGM-SAT).
Mean CGM-SAT score was 4.20 (SD: 0.87), indicating high satisfaction among participants.
92.3% of participants expressed a desire to continue using CGM post-study.
Participants achieved a mean time in tight range of 84.7% (SD: 12.10) and mean coefficient of variation of 16.5% (SD: 3.87).

Abstract

Introduction and Objective: The prevalence of diabetes continues to rise, and recent estimates indicate that 38% of US adults have prediabetes. With this trend, patient-centered and proactive strategies are essential. As continuous glucose monitors (CGMs) are now accessible over-the-counter, there is ongoing interest in their use beyond patients with established diabetes. Patient-facing data can offer real-time feedback which may inform lifestyle modification. We aimed to evaluate the acceptability of CGM use among participants with prediabetes as a first step toward more proactive care. Methods: Adult participants with prediabetes from a primary care clinic in Boston, MA were identified based on HbA1c (5.7-6.4%) and ICD-10 codes. Participants were mailed a Dexcom Stelo CGM and attended a remote onboarding session with the study team for assistance with sensor placement and set up. Our primary outcome was acceptability as measured by the CGM Satisfaction Scale (CGM-SAT) following the CGM wear period (15 days). Exploratory outcomes included time in tight range (TITR) and coefficient of variation (CV). All analyses were completed in R (version 4.5.2). Results: The cohort included 13 participants who were primarily White (N=7, 53.8%) and female (N=8, 61.5%) with a mean age of 62.7 years (standard deviation (SD): 9.81) and a mean hemoglobin A1c of 6.0% (SD: 0.24). The mean CGM-SAT score was 4.20 (SD: 0.87), indicating high satisfaction. Twelve (92.3%) participants strongly agreed or agreed that they would want to use a CGM when the research study was over. The participants had a mean TITR of 84.7% (SD: 12.10) and mean CV of 16.5% (SD: 3.87). Conclusion: We found high satisfaction with CGM use among participants with prediabetes, indicating potential use for prediabetes care. Study limitations include the single-site design, a small sample size, and only English-speaking participants. Access to CGM may empower patients with prediabetes, fostering engagement and supporting proactive, personalized diabetes prevention. Disclosure N.A. Prada-Rey: None. N.
