The 2024 ADA Standards emphasis and remind of the benefits of using intermittently scanned CGM (isCGM) in less intensively treated people with type 2 diabetes. The ADA informs that randomized, controlled trial data supporting the use of isCGM are increasing, with one of the studies exploring their use in adults with type 1 diabetes demonstrating reduction in hypoglycemia rates, establishing the intended primary endpoint. Another study conducted in adults with type 2 diabetes using insulin achieved a secondary endpoint of a reduction in hypoglycemia and confirms the impact that CGM can have in preventing dangerous episodes of low blood glucose.

Research has demonstrated that isCGM combined with optional alarms to warn users of potential glucose excursions has resulted in greater reduction of A1C levels compared with standard blood glucose monitoring. Also noted is that providing diabetes education plus implementing isCGM when compared with the use of diabetes education alone showed decreased A1C levels and increased time in range (TIR) as well as increased time in tight target range of 70 mg/dL to 140 mg/dL in the isCGM-plus-education group.

The standards also promote research that informs the persistent effects observed after 2 years of CGM, including fewer acute diabetes complications including potentially serious episodes of severe hypoglycemia or hyperglycemia, diabetes-related coma, and diabetic ketoacidosis, all which could lead to hospitalizations and additional adverse clinical consequences.

According to Nuha A. El Sayed, MD, MM Sc, who is the ADA’s senior vice president of health care improvement, “As the ADA’s chair of professional practice committee, I’m excited to share our latest updates to advance diabetes care through new scientific insights and technological innovation, all aimed at enhancing experience for people with diabetes and health care professionals in managing this complex condition.”

Echoing support for optimizing CGM use, ADA CEO Chuck Henderson commented further, “At the ADA, we are focused on improving the quality of care for anyone who lives with diabetes, prediabetes, or who is at risk of developing diabetes. The Standards of Care is critical to ensuring the improved treatment of diabetes, a chronic disease that requires continuous care through a well-informed and coordinated healthcare team. These standards equip healthcare professionals with the gold standard in diabetes care, ensuring the highest level of service and knowledge in the field.”
