Accuracy of a Continuous Glucose Monitor During Pediatric Type 1 Diabetes Inpatient Admissions
Authors' conclusion
Findings from our pediatric population were similar to accuracy reported in hospitalized adults, indicating the potential role for CGM use during pediatric hospitalizations.
Study context
- Population
- Youth with T1D during hospitalization (median age 12.0 years, 68.7% non-Hispanic white, 54.2% male), 100 admissions1,120 point-of-care (POC) and 288 laboratory-matched pairs
- Participants
- 83 participants
- Exposure
- Dexcom G6 CGM vs matched POC and laboratory glucose values
- Outcome
- CGM accuracy: MARD, Clarke Error Grids, % of CGM values within 15%/20%/30% (glucose >100 mg/dL) and 15/20/30 mg/dL (≤100 mg/dL)
Methodological detailsretrospective review, Glucose values >400 and <40 mg/dL excluded due to sensor reporting capabilities
- Retrospective review
- Glucose values >400 and <40 mg/dL excluded due to sensor reporting capabilities

- 7.9%
- MARD vs all laboratory values
- 6.5%
- Matched pairs within Clarke Error Grid A and B zones
- 98%
Observational data: associations, not effects.
