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.

Summary

This study looks at whether a coordinated emergency system, like those used for trauma, can help more severe stroke patients get a clot removal procedure called mechanical thrombectomy. Researchers will compare data from before and after the system is put in place across Alabama. About 4,893 patients with suspected large vessel occlusion strokes will be included. No new treatments are being tested; the study only observes standard care.

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 show that a coordinated emergency system helps more severe stroke patients get life-saving clot removal quickly.
What could go wrong
This is an observational study collecting standard care data, so it cannot prove cause and effect. Results may not apply to other regions or systems.
