Accuracy of a Real-Time Continuous Glucose Monitor in Pediatric Diabetic Ketoacidosis Admissions
Authors' conclusion
CGM accuracy is similar between DKA and non-DKA admissions and is maintained in severe DKA and during IV insulin administration, suggesting potential usability in pediatric hospitalizations.
Study context
- Population
- Pediatric inpatients using personal Dexcom G6 sensor during hospitalization, including diabetic ketoacidosis (DKA) admissions and intravenous (IV) insulin; median age 14 years, 58.3% non-Hispanic White, 47.2% male36 patients · 42 encounters
- Participants
- 612 vs 503
- Exposure
- Personal Dexcom G6 continuous glucose monitoring (CGM) sensor glucose vs point-of-care glucose during DKA and non-DKA admissions
- DKAn = 612
- Non-DKAn = 503reference
- Outcome
- CGM accuracy: MARD and pairs in Clarke Error Grid zones A and B
