We assessed EMS utilization for suspected stroke secondarily, using geospatial information systems analysis of Chicago ambulance transports before and after our intervention. Among 21\u00a0497 patients with confirmed ischemic stroke across all sites, early arrival rates at the intervention hospital increased by 0.5% per month (95% CI, \u22120.2% to 1.2%) after intervention compared with the preintervention period but were not different from North Side Chicago hospitals (difference of \u22120.3% per month [95% CI, \u22120.12% to 0.06%]) or St Louis hospitals (difference of 0.7% per month [95% CI, \u22120.1% to 1.4%]). EMS utilization at the intervention hospital decreased by 0.8% per month (95% CI, \u22121.7% to 0.2%) but was not different from North Side Chicago hospitals (difference of 0.004% per month [95% CI, \u22121.1% to 1.1%]) or St Louis hospitals (difference of \u22120.7% per month [95% CI, \u22121.7% to 0.3%]). EMS utilization for suspected stroke increased in the areas surrounding the intervention hospital (odds ratio [OR], 1.4; 95% CI, 1.2\u20131.6) and in the South Side (OR, 1.2; 95% CI, 1.1\u20131.3), but not in the North Side (OR, 1.0; 95% CI, 0.9\u20131.1).<\/jats:p>\n          <\/jats:sec>\n          <jats:sec xml:lang=\"en\">\n            <jats:title>Conclusions<\/jats:title>\n            <jats:p xml:lang=\"en\">Following a community stroke preparedness intervention, early hospital arrival and EMS utilization for confirmed ischemic stroke did not increase.
