SAT-512 Can Continuous Glucose Monitoring be Successful in Managing Diabetes Mellitus in the General Internal Medicine Residency Clinic-Extension Trial

Abstract Disclosure: A.E. Manov: None. The goal of our 4-year retrospective extension study was to find out if continuous glucose monitoring( CGM) can be safely introduced in an Internal medicine Residency clinic and not only a specialized Endocrine clinic for the management of Diabetes Mellitus( DM) type 1 and Type 2 who were using 3-4 injections of Insulin per day and self-monitored their blood glucose(SMBG) 4 times a day. We monitored 91- patients who SMBG 4- times a day and were given by our Internal medicine Residents CGM devices to monitor their blood glucose because of their uncontrolled diabetes. The residents functioned under the supervision of a Board-certified endocrinologist who was a member of the clinic. The residents were in contact with the assigned patients by phone every 2- weeks and were adjusting the patients’ treatment. Also, the patients were seen every 2- months by members of the CGM team in the clinic. The CGM team consulted with the endocrinologist whenever needed to ensure excellent treatment of patients’ diabetes. We achieved a reduction of HbA1c from 10.4% to 7.043% and 58% of this reduction- 1.9% was achieved in the first 3 months of the study. The average blood glucose decreased from 250 mg/dl to 154 mg/dl, reduction of the incidence of mild hypoglycemia below 70 mg/dl to 54 mg/dl from 4.1% to 0.264% per day, and more pronounced hypoglycemia with glucose less than 54 mg/dl from 1.1% per day to 0.187% per day. We observed a significant increment in the time in the blood glucose range from 18% to 63% per day. Furthermore, 10% of the patients in this study eventually discontinued their daily insulin injections and continued treatment with oral diabetic medications with or without the use of injectable GLP-1 receptors once a week.Our study adds to the excellent improvement of glucose control in managing DM by using CGM data instead of SMBG in the most difficult-to-treat patients with DM using multiple insulin injections per day. These excellent results confirm and add to the existing data that nationwide usage in internal medicine residency programs of CGM can be introduced to improve the quality of treatment of patients with DM and the education of residents in general internal medicine residency clinics in the USA.
