Background: Stroke is a leading cause of death and disability in the U
nited States. Although new treatments are being studied, most must be
given early in the course of stroke to be effective. This study was pe
rformed to identify factors associated with early hospital arrival in
patients with stroke. Methods: As part of the National Institute of Ne
urologic Disorders and Stroke Tissue-Type Plasminogen Activator Pilot
Study, information from patients, patients' families, or, most commonl
y, the medical record was gathered on all patients presenting to the h
ospital within 24 hours of the onset of stroke. A total of 14 hospital
s participated. Three were university hospitals, and 11 were community
hospitals with and without university affiliation. The main outcome m
easure was the time from stroke onset to hospital arrival. Results: Of
2099 patients screened, adequate time data were available in 1159. Th
irty-nine percent presented to the hospital 90 minutes or less after s
ymptom onset and 59% within 3 hours. Early hospital arrival after stro
ke was greatly influenced by the type of first medical contact and, to
a lesser degree, by the patient's location at the time of the stroke
and the time of the day at which the stroke occurred. Hospital arrival
was fastest in patients using 911 as their first medical contact (mea
n, 155 minutes; median, 84 minutes) vs their personal physician (mean,
379 minutes; median, 270 minutes; P<.0001) or a study hospital (mean,
333 minutes; median, 212 minutes; P<.0001). Time from symptom onset t
o arrival was longer for patients having the stroke at night compared
with patients having a stroke in the morning (P<.05), in the afternoon
(P<.01), or in the evening (P<.0001). Time to hospital arrival was si
gnificantly longer for patients having the stroke at home than for pat
ients having the stroke at work (P<.01) or in an unknown place (P<.05)
. Gender, age, race, and presence of brain hemorrhage had no significa
nt effect. Conclusions: As many as 50% of patients with stroke arrive
at the hospital within 3 hours of symptom onset. Our data indicate tha
t strategies to increase the use of 911 systems may have a high yield
with regard to recruitment into urgent treatment protocols for stroke.
