Lightning Learning: ROSIER Score

Lightning Learning: ROSIER Score

The ROSIER score is used to distinguish between suspected stroke and stroke mimics.
— advice is based on local guidelines & procedures

What?

ROSIER = Recognition Of Stroke In the Emergency Room

 

Has there been LOC or syncope?

Yes (-1)
No (0)

Has there been any seizure activity?

Yes (-1)
No (0)

Is there NEW ACUTE ONSET?

Asymmetrical facial weakness?

Yes (1)
No (0)

Asymmetrical arm weakness?

Yes (1)
No (0)

Asymmetrical leg weakness?

Yes (1)
No (0)

Speech disturbance?

Yes (1)
No (0)

Visual field defect?

Yes (1)
No (0)

 

Total Score: ______ (between -2 and +5)

 

Why?

It is used to distinguish between suspected stroke and stroke mimics.

Developed to achieve rapid diagnosis of suspected strokes to ensure patients are identified within the thrombolysis window as much as possible.

If score > 0 (stroke is likely)
If score </= 0 (stroke is unlikely but not completely excluded!)

Patients with suspected TIA (symptoms have resolved) should be assessed for risk of subsequent stroke using ABCD^2 score.
