The Role of Professional Continuous Glucose Monitoring in Type 2 Diabetics Not On Insulin

Objective : There is little data to support the use of professional continuous glucose monitoring (CGM) to improve glucose control in type 2 Diabetics, not on insulin. Professional CGM is able to provide information about glucose patterns, glucose control and hypoglycemia. This study looked for an improvement in A1C measurements after use of a professional CGM.

Methods: We evaluated patients with Type 2 Diabetes who do not use insulin who wore a professional CGM (IPRO 2-Medtronic) over a 48 month period in a clinical endocrinology practice. Patients who had an A1C on file within 90 days of wearing the CGM and a follow-up A1C 90 to 180 days after wearing the CGM were included in the analysis. There were 97 patients included in the analysis.

Results: On average the baseline A1C was 7.94% which improved to 7.29% after wearing the CGM.

Discussion/Conclusion: We conclude that non-insulin using patients can benefit from targeted medication changes and lifestyle intervention based on the guidance of a professional CGM. This is important as non-insulin receiving patients are less likely to have a home CGM or perform glucose monitoring.
