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 Results may not be published yet.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.

Summary

This study tests whether a set of simple decision rules, adapted from the Canadian C-Spine Rule, can help emergency responders decide when a neck collar and hospital imaging are truly needed. Researchers will enroll 840 stable, conscious adults with recent neck trauma treated by ambulance or fire services in France. The goal is to see if using these rules reduces unnecessary hospital visits and imaging without missing serious injuries.

What this could mean

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

Active substance
adapted Canadian C-Spine rules (behavioral intervention)
What this could lead to
If successful, this could lead to fewer unnecessary neck collars and X-rays for stable trauma patients, speeding up care and reducing discomfort.
What could go wrong
This is an observational study, not a treatment trial. The rules may not work as well in real-world emergency settings, and there is a small risk of missing a serious neck injury.
