Accuracy of continuous glucose monitoring in critically ill patients.

ABSTRACT:

Objective

Hyperglycaemia requiring insulin infusions is common among critically ill patients. Attempts to tightly control glucose levels in the intensive care unit (ICU) have had mixed results partly due to hypoglycaemia. Continuous glucose monitoring (CGM) has been widely adopted among ambulatory persons with diabetes but tested only on small numbers of patients in the ICU. This study was undertaken to address the accuracy of CGM in a group of critically ill patients.

Setting and outcomes

This observational study included critically ill ICU patients admitted between 2019 and 2023 to a tertiary referral, university-affiliated hospital with a single 19-bed ICU. Patients requiring insulin to control hyperglycaemia had a sensor (Dexcom G4 or G6) attached. Accuracy was assessed
