Can a smart glucose monitor keep diabetics out of the hospital?
NCT ID NCT07221812
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether giving people with diabetes a continuous glucose monitor (CGM) when they leave the hospital helps them control their blood sugar better than traditional finger-stick testing. 120 participants will be randomly assigned to use either a CGM or finger sticks for 3 months after discharge. The goal is to see if the CGM leads to fewer hospital readmissions and better overall glucose management.
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 Monitor (Dexcom G7)
- What this could lead to
- If successful, this could show that using CGMs after hospital discharge helps people with diabetes better control their blood sugar and avoid returning to the hospital.
- What could go wrong
- This is a small, early-stage study (120 people) at a single VA center, so results may not apply to everyone. The device itself is generally safe, but false alarms or user error could cause stress or incorrect treatment decisions.
