Creating Linked Inpatient CGM for Kids Study

This observational study at Boston Children's Hospital is looking at how well a new mobile app can get real-time data from the Dexcom G7 Continuous Glucose Monitor (CGM) for children with diabetes who are staying in the hospital. Currently, CGM data isn't immediately available to doctors and nurses, which means they have to check it manually. This study aims to see if this new app can accurately capture CGM data, making it easier for care teams to monitor blood sugar levels. We are looking for about 20 inpatients with diabetes, aged 2 weeks to 24 years, who are using a Dexcom G7 CGM and its phone app. The main goal is to measure how accurately the CGM data is captured by the app, with measurements taken for up to 20 days or 72 hours after the first sensor change.

Study design
This is an observational study with a planned enrollment of 20 participants. It is not specified if it is randomized or blinded.
What's involved
You would need to be an inpatient with diabetes using a Dexcom G7 CGM and its phone app, sharing data with the BCH Dexcom Clarity Database. Your anticipated discharge date must be more than 24 hours after you become eligible.
Compensation
Not stated in the trial record.
Follow-up
The accuracy of CGM data capture will be measured for a maximum of 20 days or 72 hours following the first sensor exchange.

What this trial measures

  • Accuracy of CGM data capture.The earlier of a maximum of 20 days or 72 hours following the first sensor exchange.

    The accuracy of the CGM readings captured will be measured as the mean absolute relative difference (MARD) between the CGM glucose reading captured by the companion app compared to the CGM glucose reading documented in the Dexcom Clarity database within the same 5-minute interval.
