Clinical accuracy of Dexcom G6 and G7 continuous glucose monitors in hospitalized pediatric patients with type 1 diabetes: a real-world study
Purpose: Continuous glucose monitoring (CGM) is increasingly being used in inpatient pediatric diabetes care; however, data on its real-world accuracy remain limited.Methods: We retrospectively assessed the clinical accuracy of factory-calibrated Dexcom G6 and G7 CGM systems in 69 pediatric patients with type 1 diabetes at a Korean tertiary hospital between 2019 and 2025. A total of 1,838 CGM readings were temporally paired with point-of-care (POC) capillary glucose measurements. Accuracy was evaluated using the me …
