Continuous Glucose Monitoring in Hospitalized Patients with Diabetes Mellitus


About this study

The purpose of this study is to determine if patient’s own Continuous Glucose Monitoring (CGMs) worn in the non-ICU hospital setting have adequate accuracy for blood glucose monitoring when compared to point-of-care capillary glucose measurement, and to determine if alerts given by CGMs worn in the non-ICU hospital would prevent episodes of hyperglycemia and hypoglycemia.
