Experts Find Continuous Glucose Monitoring Beneficial In Maintaining Target Blood Glucose Levels
Patients with diabetes face daily challenges in managing their blood glucose levels, and it has been postulated that patients could benefit from a system providing continuous real-time glucose readings. Today, The Endocrine Society released a clinical practice guideline (CPG) providing recommendations on settings where patients are most likely to benefit from continuous glucose monitoring (CGM).
The most common way to self-check blood glucose levels is to prick the skin to get a drop of blood, put the blood on a test strip, and insert it in a glucose meter. CGM, though, measures glucose in the interstitial fluid–the fluid between body cells just under the skin. People with both type 1 and type 2 diabetes use the results of blood glucose tests to make decisions about food, medicines and exercise.
Recommendations from The Endocrine Society's CPG include:
Use of CGM with currently approved devices in children and adolescents with type 1 diabetes mellitus (T1DM) because it will assist in maintaining target HbA1c levels while limiting the risk of hypoglycemia;
Use of CGM devices by adult patients with T1DM who have demonstrated they can use these devices on a nearly daily basis; and
Refrainment from using CGM alone for glucose management in the intensive care unit or operating room until further studies provide sufficient evidence for its accuracy and safety in those settings.
The Hormone Foundation, the patient education affiliate of The Endocrine Society, has published a companion patient guide to this CPG. The patient guide, which can be found online at www.hormone.org/glucose, explains how CGM works and who could most benefit from its use.
