The emergency medical dispatcher (EMD) receiving a call via 911 is the first point of contact within the acute care system and plays an important role in early stroke recognition. Published studies show that the diagnostic accuracy of stroke of EMD needs to be improved. Therefore, the National Association of Emergency Medical Dispatchers implemented a stroke diagnostic tool modelled after the Cincinnati stroke scale across 3000 cities worldwide. This is the first time a diagnostic tool that requires callers to test physical findings and report those back to the EMD has been implemented. However, the ability of EMD and 911 callers to use this in real time has not been reported. The goal of this pilot study was to determine the feasibility of an EMD applying the Cincinnati stroke scale tool during a 911 call, and to report the time required to administer the tool.
