Continuous Glucose Monitoring–Guided Insulin Infusion in Critically Ill Patients Promotes Safety, Improves Time Efficiency, and Enhances Provider Satisfaction
Authors' conclusion
Integrating rtCGM with an IICC protocol in the ICU enhances glycemic control, improves workflow efficiency, and reduces clinician workload while maintaining high accuracy.
Study context
- Population
- Critically ill adults requiring insulin infusion in surgical and medical intensive care unit (ICUs)
- Participants
- 35 adults1,291 matched glucose pairs
- Exposure
- Real-time CGM (rtCGM) integrated into an insulin infusion computer calculator (IICC); CGM accuracy vs point-of-care (POC) glucose
- rtCGM-IICCn = 35
- Outcome
- rtCGM accuracy vs POC glucose (1291 matched pairs)
Methodological detailssingle-group, surgical and medical ICUs
- Single-group
- Surgical and medical ICUs
Main finding
As reported in the abstract
Mean absolute relative difference (MARD) of rtCGM
12.5%
Values within clinically acceptable error zones (A+B), Parkes Error Grid
99.6%
Observational data: associations, not effects.
Further findings
| Outcome | Values |
|---|---|
| CGM glycaemic metricsMean glucose | rtCGM-IICC mean 141.9 mg/dL · mean TIR (70-180 mg/dL) 82.8% · TAR (> 180 mg/dL) 14.5% · TBR (< 70 mg/dL) 0.5% |
Clinician turnaround time for glucose monitoring
- Clinician time efficiency improved significantly: POC testing mean turnaround nearly 5 minutes vs 3-second CGM retrieval
Nurse satisfaction
- All surveyed nurses reported rtCGM increased efficiency and improved safety and preferred rtCGM with POC over POC alone
- n = 20
