Can a wearable glucose sensor be trusted in the ICU? new study aims to find out
NCT ID NCT07611721
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study is checking how accurate the Dexcom G7 continuous glucose monitor is for patients in the intensive care unit after major abdominal surgery or organ transplant. Researchers will place two sensors on each patient—one that is calibrated and used to guide insulin dosing, and one that is not calibrated and kept hidden. By comparing the readings from both sensors to standard blood glucose measurements, they hope to determine whether the device can reliably detect dangerous highs and lows in blood sugar in critically ill patients.
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 monitor (device)
What this could lead to
If successful, this could show that the Dexcom G7 is reliable enough for routine use in intensive care, potentially improving glucose management for critically ill patients.
What could go wrong
This is a small, early-stage accuracy study (62 participants) in a specific ICU setting, so results may not apply to all patients or general hospital wards. The device may still have errors in detecting very low or high blood sugar.
