CGM Use in COVID19 Patients (Infection With Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2))
CGM Use in COVID19 Patients (Infection With Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2))
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.
Study participation involves placement of a continuous glucose monitor (CGM) on the abdomen
 of hospitalized patients who have a diagnosis of COVID19. The CGM will measure glucose levels
 every 5 minutes which will be accessible for viewing using a receiver phone placed outside
 the patient's room and/or an iPad located at the nursing station.

 Alarm limits for hypoglycemia and hyperglycemia will be set on the receiver phone for nursing
 staff to review. These alarms settings will vary depending on whether the patient is on IV
 insulin infusion vs. subcutaneous (SQ) insulin. The number of glucose checks required with
 these two types of insulin varies significantly and requires separate handling.

 Hospital glucometers will be used to confirm the accuracy of CGM readings during an initial
 "Adjustment Phase" of the study. If CGMs are found to be accurate, then finger-stick
 glucometer check frequency will be decreased, and some of the CGM values will be used to dose
 insulin therapy during the "Utilization Phase" of the study. The instructions for these
 phases will differ for patients on IV insulin infusion vs. SQ insulin infusion and are
 detailed in separate protocols. Nursing staff will choose the appropriate protocol at the
 time of CGM placement based on the type of insulin the patient is receiving.

 Different patient variables (demographics, comorbidities, labs and vitals, administered
 medications) will be collected from electronic health record and will be evaluated to
 determine if they interfere with CGM readings. At the time of discharge, patients will
 receive a survey regarding satisfaction with the use of CGM monitors to manage their diabetes
 during their inpatient stay.
