The effect of prehospital notification by emergency medical service on outcomes in patients receiving recombinant tissue-type plasminogen activator (r-tPA).

According to the American Heart Association and American Stroke Association (AHA/ASA) guidelines, in acute stroke, the door-to-computed tomography (CT) scan (DTC) time should be less than 25 minutes, and time to injection of recombinant tissue-type plasminogen activator (r-tPA) [door-to-needle (DTN) time] should be less than 60 minutes. We had a tendency to prospectively collect the clinical and time information of patients who received r-tPA during one year after the initiation of prehospital notification (PN). Patients were divided into three groups, covering patients transferred by Emergency Medical Service (EMS) with and without PN, and non-EMS.
