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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tests a computer program that learns from past surgeries to suggest the best doses of blood-pressure medicines during an operation. About 40 adults having planned non-cardiac surgery will be randomly assigned to either standard care or care where the doctor sees the AI's suggestions. The goal is to see if the AI's advice matches what experienced anesthesiologists would do, and whether it helps keep blood pressure in a safer range.

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

Participants

About 40 people

The number the study aims to enrol. It can still change while the study runs.

Expected to start
