Rigshospitalet and Bispebjerg Hospital
Adult patients with diabetes mellitus who a) undergo surgery lasting >45 minutes or b) are admitted to the intensive care unit (ICU) with circulatory impairment (requiring continuous infusion of vasopressors and a reduced peripheral perfusion).
Included patients will wear a continuous glucose monitoring (CGM) device (Dexcom G7) during the stay at the hospital (up to 10 days). Through a sensor placed subcutaneously, the Dexcom G7 measures glucose levels every 5 minutes and transmit readings this to a receiver at the patient bed. The glucose readings will be blinded to the patients and nursing staff. Thus, the patients’ glucose levels will be monitored through standard practice with point-of-care (POC) blood glucose measurements. After the study period, the accuracy of CGM readings will be assessed by comparing these to POC blood glucose measurements.
The primary outcome is the accuracy of the CGM device compared to standard POC blood glucose measurements.
