Background: NICE 2022 updated guidelines and the updated Irish guidelines (launched on 10th May 2024) in type 1 diabetes (T1D) in adults recommend the use of continuous glucose monitoring (CGM) based on individual preferences and needs. This study aimed to evaluate the outcomes of Dexcom real-time CGM (rt-CGM) in adults with T1D attending our regional diabetes service.
Methods: A retrospective data analysis was conducted from the Dexcom Clarity platform for adults with T1D (≥16 years), who were sharing the data with our service up to April 2024.
Results: rt-CGM metrics data from 173 adults with T1D were studied. The median age of the cohort was 38 years (IQR = 22), with a gender distribution of 98 males and 75 females. 18% used Dexcom G6 and 82% were on Dexcom G7. Median Time in Range (TIR) was 43% (IQR=31), Time Below Range (TBR) was 1% (IQR=3), Glucose Management Indicator was 8% (IQR=1.5), glycaemic variability was 35% (IQR=8.2) and Time CGM Active was 97% (IQR=6.4). High engagement with rt-CGM was observed with 96% regularly wearing their devices (>70% active CGM time). However, only 12% met the recommended target TIR>70%. When the study cohort was categorized into three age groups, 4.9% (16-25 years), 16.9% (25-45 years), and 10.9% (>45 years) achieved the recommended TIR >70%. Conversely, 82.9% (16-25 years), 77.9% (25-45 years) and 76.4% (>45 years), maintained TBR<4%.
Conclusion: Our study revealed a strong adherence to rt-CGM use among adults with T1D. Majority of rt-CGM users achieved TBR targets, indicating the benefit of reduced hypoglycaemia likely due to rt-CGM hypo alerts. However, only a small proportion of rt-CGM users met the recommended TIR target. Enhanced patient education, continuous provider training, and improved integration of CGM data into clinical practice are recommended to optimize diabetes care outcomes.
