Summary

This completed study looked at whether the Dexcom G7 continuous glucose monitor stays accurate in diabetes patients who have poor blood circulation during hospital stays. Researchers compared CGM readings to standard finger-stick blood tests in 60 adults undergoing surgery or in the ICU. Participants wore a blinded CGM device for up to 10 days while receiving usual care.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: Dexcom G7 Continuous Glucose Monitoring (CGM) System
What this could lead to: If successful, this could confirm that the Dexcom G7 works reliably even when blood circulation is poor, improving diabetes monitoring in hospitals.
What could go wrong: This is a small observational study (60 people) that only checks accuracy, not treatment outcomes. Results may not apply to all patients or settings.
