Clinical Implications of Real-Time and Intermittently Scanned Continuous Glucose Monitoring
This paper reviews the features and available evidence supporting use of both real-time continuous glucose monitoring (RT-CGM) and intermittent scanning CGM (IS-CGM), offering guidance for patient selection for each type of system. RT-CGM systems (such as those provided by Dexcom) automatically and continuously provide real-time glucose data to a display device and actively alert the user to lows and highs. IS-CGM users must make a conscious decision to scan the sensor to obtain glucose data.*

*Abbott’s Freestyle Libre was the only FDA-approved isCGM on the market at the time of article publication; since then the Freestyle Libre 14 day has been approved and FreeStyle Libre 2 has been FDA cleared.

The clinical benefits of real time continuous glucose monitoring (rtCGM) use have been well demonstrated in both continuous subcutaneous insulin infusion (CSII) and multiple daily injections (MDI)...
In this novel study, investigators examined not only the benefits of continuous glucose monitoring (CGM) augmented insulin therapy, they also looked at the impact of CGM separately in subjects on...
