Real-world Accuracy of Continuous Glucose Monitoring (CGM) in Inpatient Critical and Noncritical Care Settings at a Safety-Net Hospital
Authors' conclusion
Real-world accuracy of inpatient CGM is acceptable for NCI and CI patients. Further exploration of conditions associated with lower CGM accuracy in real-world settings is warranted.
Study context
- Population
- Hospitalized patients on Dexcom G6 CGM in a large safety-net hospital; 239 encounters (83 not critically ill (NCI), 156 CI)233 patients
- Participants
- 2,744 vs 3,705
- Exposure
- CGM vs point of care (POC) and laboratory (Lab) glucose
- POC-CGMn = 2,744
- Lab-CGMn = 3,705
- Outcome
- Real-world accuracy of inpatient CGM (mean absolute relative differences (MARD), Clarke Error Grid zones A/B)
