Comparative Evaluation of Stroke Triage Algorithms for Emergency Medical Dispatchers
Pilot Prospective Cohort to Determine the Comparative Diagnostic Accuracy of Card 28 to Card 28 and Cincinnati Stroke Scale.

This study will compare the diagnostic accuracy of Card 28 stroke protocol to Card 28 and Cincinnati Stroke Scale, when used by emergency medical dispatchers to interrogate a 911 call suggestive of stroke.

The authors hypothesize that a combination of Card 28 plus the Cincinnati Stroke Scale (CSS) will improve the diagnostic accuracy of emergency medical dispatchers for stroke.
