Accuracy of Continuous Glucose Monitoring in Patients With Diabetes. A Prospective Observational Study

Denmark60 participantsStarted 2024-04-01

Plain-language summary

The goal of this observational study is to investigate the accuracy of the continuous glucose monitoring (CGM) compared to standard point-of-care (POC) blood glucose measurements in patients with diabetes in patients who during their hospital admission can experience circulatory impairment. The main questions it aims to answer are: • Do CGM measurements have a decreased accuracy compared to standard blood glucose measurements in periods with circulatory impairment? Participants will be asked to wear a blinded CGM device (Dexcom G7, Dexcom Inc.) during their stay in the hospital but will receive standard care of their diabetes. The CGM device will be worn for up to 10 days.
