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.
