NCT ID NCT04937361
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This completed study monitored over 14,000 hospital patients for multidrug-resistant organisms (MDROs) by taking rectal swabs and tracking bloodstream infections. Researchers analyzed the bacteria's genetics and how they resist antibiotics, aiming to understand how resistance emerges and spreads. The study also looked at how COVID-19 infection control measures affected hospital-acquired infections.
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 research could help hospitals better track and control the spread of drug-resistant bacteria, improving infection prevention strategies.
- What could go wrong
- This is an observational study, not a treatment trial. It does not test any new drug or intervention, so it cannot directly lead to a cure or therapy.
