Summary

This observational study looks at how common adverse events (medical errors or complications) are among hospitalized adults in China and compares four different ways to detect them. Researchers review medical records from five hospitals to identify events, assess their severity and preventability, and evaluate methods like trigger tools and incident reporting systems. The goal is to find the most reliable detection approach to 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 successful, this study could identify the most effective way to detect adverse events in hospitals, leading to better patient safety practices.
What could go wrong
As an observational study, it does not test a new intervention, so it cannot directly improve safety. Results may vary across different hospital settings.
