Analysis: The Accuracy and Efficacy of the Dexcom G4 Platinum Continuous Glucose Monitoring System.
In this issue of Journal of Diabetes Science and Technology, Nakamura and Balo report on accuracy and efficacy of the Dexcom G4 Platinum Continuous Glucose Monitoring System. The authors demonstrate good overall performance of this real-time continuous glucose monitoring (RT-CGM) system, although accuracy data of the next generation RT-CGM system, the G4AP, is already available. Also, now that MARDs seem to move to single-digit numbers, the question comes up how low we need to go with accuracy. Results of the study also showed a reduction in time spent in hypoglycemia, although the clinical relevance should be questioned. To date, few trials have demonstrated a reduction of severe hypoglycemia. Conventional RT-CGM, without threshold suspension or closing the loop, might be insufficient in preventing severe hypoglycemia.
