Ischemic stroke patients 20 years old or older who presented to 15 hospitals within a 5-county region of Greater Cincinnati/Northern Kentucky during 2010 were included. Time from symptom onset to ED arrival and covariates were abstracted by study nurses and reviewed by study physicians. Data were analyzed using logistic regression with time to arrival dichotomized at 3 hours or less in the overall sample and then stratified by National Institutes of Health Stroke Scale (NIHSS) and age.
1991 strokes (55% women) were included. Time to arrival was slightly longer in women (geometric mean 337 minutes [95% confidence interval {CI} 307-369] versus 297 [95% CI 268-329],
After adjusting for factors including age, NIHSS score, and living alone, women and men with ischemic stroke had similar times to arrival. Arrival time is not likely a major contributor to differences in outcome between men and women.
