NCT ID NCT04096885

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.

Summary

This study collects blood, urine, skin, and stool samples from over 1,200 surgery patients to see if changes in the body's chemistry can predict surgical site infections. The goal is to find a biological test that helps personalize surgical care. No treatment is being tested—only samples are taken before and after surgery.

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 lead to a simple test to predict which patients are at risk of surgical site infections after surgery.
What could go wrong
This is an observational study, not testing a treatment. It may not find reliable predictors, and results may not apply to all hospitals or surgeries.

This is an AI summary of the original study and may miss details. Read our disclaimer.
