Continuous Glucose Monitor (CGM) Use in COVID-19 Patients


About this study

The purpose of this research is to determine if CGM (continuous glucose monitors) used in the hospital in patients with COVID-19 and diabetes treated with insulin will be as accurate as POC (point of care) glucose monitors. Also if found to be accurate, CGM reading data will be used together with POC glucometers to dose insulin therapy.
