Background: Hyperglycemia is common in Intensive Care Unit (ICU) and was reported with high mortality and adverse patients’ outcomes. The infection of COVID-19 is identified as a main source of increase in the incidence of hyperglycemia and associated elevated mortality. In order to reduce the healthcare providers exposure and the personal protective equipment use during the pandemic, the US Food and Drug Administration (FDA) regulated the usage of continuous glucose monitoring (CGM) devices to address these concerns as well as control the glucose level at a desired range. What are the benefits of using CGM applications? The article updates knowledge on this topic.

Methods:We did our search on the following databases: MEDLINE, EMBASE and Cochrane database, articles included were all recent and between January 2020 to July 2022. Our main focus was on articles with evidence concerning the effectiveness and the accuracy of continuous blood glucose monitoring methods in ICU during the COVID-19 pandemic.

Results: A few recent articles were identified and scrutinized. These allow the article to present an overview of the most recent international evidence on the topic, ts benefits and a comparison between methods and devices.

Main Contribution to Evidence-Based Practice: The article puts together the most recent evidence on the demonstrated benefits of continuous glucose monitoring and identifies the few glucose Monitoring Devices about which there is recent published scientific evidence on its application to critical care.
