NCT ID NCT04552834
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study follows 500 adults admitted to the intensive care unit to see how their gut bacteria (microbiome) change during critical illness. Researchers will track deaths and recovery up to one year later. The goal is to understand whether these bacterial shifts affect short- and long-term outcomes.
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 successful, this could help doctors understand how gut bacteria affect recovery from critical illness, potentially leading to new ways to improve outcomes.
What could go wrong
This is an observational study, not a treatment trial. It will not directly test any therapy, and results may not lead to immediate changes in patient care.
