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.
Paused
Paused for now. It may or may not start again.
Ongoing This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 whether improved telephone instructions for CPR can reduce the time without chest compressions when using an AED. About 80 volunteers will act as single rescuers in a simulated cardiac arrest. Half will get standard phone CPR guidance, and half will get enhanced instructions that focus on minimizing interruptions and optimizing AED use. The goal is to see if the new instructions lead to more continuous chest compressions and faster defibrillation.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
telephone-assisted CPR instructions
What this could lead to
If successful, this could lead to improved dispatcher instructions that help bystanders perform CPR more effectively with an AED, potentially increasing survival from cardiac arrest.
What could go wrong
This is a simulation study with 80 participants, not a real-life trial. Results may not translate to actual emergencies, and the benefit may be small or not noticeable.

Participants

About 80 people

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

Started

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.
