Summary

This trial tests whether using a continuous glucose monitor (CGM) before and after major surgery can reduce complications in adults with diabetes or impaired glucose tolerance. Participants wear the device for at least 6 hours before surgery and up to 7 days after, while a comparison group receives standard glucose checks. The goal is to see if CGM leads to fewer and less severe complications within 30 days after surgery.

What this could mean

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

Active substance: continuous glucose monitoring (CGM) device
What this could lead to: If effective, CGM could become a standard tool to reduce post-surgical complications in people with diabetes.
What could go wrong: This is a large pragmatic trial, but the benefit of CGM over conventional monitoring in surgical settings is not yet proven, and device calibration or patient adherence may affect results.
