10: CGM Accuracy (Part 1) "Study Design First, Performance After"

Suggest guests or get in contactIn this episode of the Glucose Never Lies podcast, hosts John Pemberton and Louise delve into the intricacies of diabetes management, focusing on continuous glucose monitoring (CGM) systems. They discuss the importance of understanding CGM accuracy, the significance of study design in evaluating sensor performance, and the key questions to ask when assessing the reliability of these devices. The conversation emphasises the need for robust testing conditions to ensure that CGMs provide accurate readings for insulin dosing decisions. The hosts also highlight the ongoing efforts towards standardisation in CGM technology to improve diabetes care.TakeawaysContinuous glucose monitors (CGMs) are crucial for insulin dosing decisions.Understanding study design is essential for evaluating CGM accuracy.Not all CGMs are created equal; performance varies significantly.Key questions to assess CGM accuracy include the study population and testing conditions.Robust testing conditions are necessary for reliable sensor performance.The importance of peer-reviewed data in evaluating CGM accuracy.Standardization in CGM technology is on the horizon.Healthcare professionals should be knowledgeable about CGM performance.A downloadable chart will be available to help users assess CGM options.Chapters00:00Introduction to Diabetes Management02:14Understanding Continuous Glucose Monitoring (CGM)05:11Accuracy of Continuous Glucose Monitors10:13Evaluating Sensor Performance15:45Key Questions for Sensor Accuracy20:31Moving Towards Standardization in CGM25:03Summary and Next StepsKey ResourcesCGM Series: Understanding Risk Before PerformanceChart for CGM Devices (From May 2025): DSN ForumTim Street @ Diabettech Support GNL: https://buy.stripe.com/9B63cx4UO3KEdKC0Sp7Re00The Glucose Never Lies® is a registered trademarDisclaimerThis podcast is for education and informational purposes only.
