Accuracy of a Continuous Glucose Monitor in the Intensive Care Unit: A Proposed Accuracy Standard and Calibration Protocol for Inpatient Use
Authors' conclusion
Our protocol achieved the lowest MARD and safest CEG profile in the critical care setting and well exceeds the critical care expert recommendations.
Study context
- Population
- Adults on an insulin infusion in a medical-surgical ICU; mean age 57.29 (SD 2.39) years, 13 with prior diabetes, 14 admitted for a surgical diagnosis
- Participants
- 28 adults1,064 matched pairs
- Comparison
- Dexcom G6 with calibration protocol vs without calibration, against arterial point-of-care glucose
- Calibratedn = 9
- Uncalibratedn = 19reference
- Outcome
- MARD vs arterial point-of-care glucose
