Abstract

Background: Tissue plasminogen activator (tPA), the only approved treatment for acute ischemic stroke (IS), is significantly underutilized likely due to poor lay information about stroke as an emergency. In order to improve outcomes in acute IS, it is critical to raise awareness and recognition of stroke symptoms particularly among minority populations. This manuscript describes the application of a stroke preparedness behavioral intervention and includes baseline information in a multi-ethnic population of stroke and transient ischemic attack (TIA) survivors. Methods: In the Stroke Warning Information and Faster Treatment Study (SWIFT), we prospectively identified, and randomized IS and TIA patients to determine efficacy of a culturally tailored interactive stroke preparedness strategy. Data collected at baseline included acute stroke parameters, stroke knowledge, severity, social resources and vascular risk assessment. Results: Of the 736 enrolled to date, 76% were IS and 24% TIA events. The cohort was 51% female: 45% Hispanic, 26% White and 25% Black. Over 75% reported hypertension, 36% diabetes, and 16% cardiac disease. Mean time from onset to emergency department (ED) arrival was 46 h (median 13 h) differing significantly between Whites (mean 52 h, median 11 h) and Blacks (mean 52 h, median 17 h) versus Hispanics (mean 39 h, median 11 h). Knowledge that a stroke occurs in the brain differed significantly by between Whites (85%), Blacks (64%), Hispanics (66%, p < 0.000). Conclusions: Disparities remain in both action and knowledge surrounding acute stroke. Use of written information has not proven an effective means of changing health behaviors. We propose an interactive culturally tailored intervention to address behavioral change in acute stroke.
