All patients 18 years and older, transported by ambulances (<italic>n =</italic> 309, 866) within the two counties, and patients with hospital‐based discharge diagnoses of stroke (<italic>n =</italic> 10, 719) were included in the study.

Of those, 3, 787 (35%) were transported by emergency medical services providers. Overall, 32% of patients ultimately diagnosed with stroke were identified in the prehospital setting. Correct prehospital recognition of stroke was lower among Hispanic patients (odds ratio [OR] = 0.77, 95% confidence interval [CI] 0.61 to 0.96), Asians (OR = 0.66, 95% CI 0.55 to 0.80), and others (OR = 0.71, 95% CI = 0.53 to 0.94), when compared with non‐Hispanic whites, and in women compared with men (OR = 0.82, 95% CI = 0.71 to 0.94). Specificity for recognizing stroke was lower in females than males (OR = 0.84, 95% CI = 0.78 to 0.90).</p> </sec> <sec id="acem12595-sec-0004" sec-type="section"> <title>Conclusions</title> <p>Significant disparities exist in prehospital stroke recognition.</p> </sec> </abstract>
