The objective of the study is to improve glycemic control in inpatient/ICU settings using real- time continuous glucose monitors (CGM) data for insulin titration. It may help reduce Coronavirus disease 2019 patient contact with healthcare workers as well.

Due to the increasing need for acute care of COVID-19 patients in ICU settings, the use of continuous glucose monitors (CGM) as a means to reduce patient contact and remotely improve glycemic control for diabetic COVID-19 patients needs to be explored. As demonstrated by recent data published in China, Wuhan province patients with diabetes made up 22.2% of COVID-19 ICU patient populations with a subsequent mortality of 7.3% (3). Not only during COVID-19 pandemic but also previous experiences with SARS and influenza viral respiratory infections demonstrated increased mortality in those patients with hyperglycemia (4).

Using CGMs provides timely access to glucose trends, commonly used to determine insulin dosing decisions in outpatient settings (5). Implementing their use for hospitalized patients could be expected to improve healthcare worker insight into glycemic control therapies.

Considering the ease of transmission of the SARS-Cov-2 virus, it is important to minimize duration and frequency of patient contact in order to maintain the safety of COVID-19 healthcare workers without compromising on their glycemic control. The WHO recommends that any healthcare provider coming into direct contact with COVID-19 patients should be utilizing appropriate PPE for each encounter. In this time of limited PPE supply (6), remote glucose monitoring can allow for rational use of these limited resources. With appropriate training on CGM data interpretation, nursing and ordering providers could expect to develop and implement more efficient insulin plans, requiring fewer physical contact with COVID-19 positive patients.
