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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 machine learning and special brain injury markers in blood and spinal fluid can warn doctors early when a patient with a brain bleed is developing delayed cerebral ischemia (lack of oxygen to the brain). Researchers will monitor 1,500 adults in intensive care using heart rate, brain waves, and oxygen sensors. The goal is to build an early warning system that could help prevent lasting brain injury.

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 create an early warning system to detect brain oxygen deprivation sooner, potentially reducing brain damage and improving recovery after bleeding in the brain.
What could go wrong
This is an observational study, not a treatment trial. The machine learning model may not be accurate enough in real-world settings, and the results may not apply to all patients.

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