What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study is testing whether artificial intelligence can predict which patients will develop hospital-acquired pneumonia after heart or vascular surgery. It will also investigate whether pneumonia after surgery is linked to a higher risk of heart and lung problems within the following year. The research will use data from 700 adult patients to develop personalized risk calculators, potentially helping doctors identify high-risk patients earlier.

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 personalized risk calculators that help doctors predict and prevent pneumonia after heart surgery, and identify patients at higher risk for long-term heart and lung complications.
What could go wrong
This is an observational study, so it can only show associations, not cause and effect. The AI models may not be accurate enough for widespread use, and results may not apply to all patient populations.

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