What is the clinical effectiveness of monitoring glycemia with rtCGM for adults living with type 1 diabetes?
What is the clinical effectiveness of monitoring glycemia with rtCGM for pediatric patients living with type 1 diabetes?
What is the cost-effectiveness of monitoring glycemia with rtCGM for people living with type 1 diabetes?

Continuous glucose monitoring (CGM) is a method of glucose testing in which a sensor is inserted into the skin and continuously monitors interstitial glucose concentrations. Real-time continuous glucose monitoring (rtCGM) systems automatically measure glucose and display a recent glucose value.
Evidence suggests that rtCGM may improve hemoglobin A1C and time in range in adults and pediatric patients with type 1 diabetes, but this is uncertain.
Limited evidence suggests that in people with type 1 diabetes, there is little to no difference between rtCGM and self-monitoring of blood glucose (SMBG) on quality of life, diabetic ketoacidosis, and severe adverse events.
Safety evidence suggests that rtCGM may decrease severe hypoglycemia in adults and pediatric patients with type 1 diabetes, but this is uncertain.
rtCGM may be more cost-effective in the long term than SMBG in adults with type 1 diabetes.
