We studied the time of arrival of 235 consecutive patients admitted to the emergency department of a University Hospital located in a rural area after the first symptoms of ischemic stroke or TIA. Among the following factors, we determined those that might be involved in delayed admission: place of symptom onset, time and place of onset of the first symptoms, contact with a general practitioner before admission time, mode of transportation, clinical score, impairment of consciousness, presence of seizures, heart complaints or headache, age and past medical history of cerebrovascular, cardiovascular and hypertension diseases. Half of the patients arrived within 4 h 10 of symptom discovery and 55 p. cent arrived within 6 hours. The percentage of patients arriving within 3 h (p = 0.001) and 6 h (p = 0.001) was higher for those who had a stroke during the day (8 a.m.-8 p.m.) than during the evening and night. The other characteristics associated with a shorter delay included a low neurological score on the Mathew's Stroke Scale (p < 0.001 at 3 h and p = 0.001 at 6 h) and younger age (p = 0.015 at 3 h). Presence of headache delayed admission (p = 0.010). Forty-five percent of patients arrive at the hospital 6 hours after the discovery of symptoms, too late to receive optimal stroke therapy. Widespread public education on stroke is necessary to reduce the delay of admission, particularly for old patients and in case of mild to moderate deficits.
