Did hospitals follow the rules? new study examines diabetes care before, during, and after major surgery
NCT ID NCT07349199
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This completed study looked at how well Danish hospitals followed official guidelines for managing blood sugar in people with diabetes who had major, non-cardiac surgery. Researchers reviewed records from over 13,000 patients treated between 2017 and 2023. They focused on whether the right amount of insulin was given when blood sugar was too high, aiming to identify gaps in care and improve patient safety.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If the findings show where care often falls short, they could help hospitals improve diabetes management around surgery, potentially reducing complications.
- What could go wrong
- This is an observational study looking back at past records, so it cannot prove cause and effect. The results may not apply to other countries or healthcare systems.
