Methodology for a community-based stroke preparedness intervention: the Acute Stroke Program of Interventions Addressing Racial and Ethnic Disparities Study.

BACKGROUND AND PURPOSE Acute stroke education has focused on stroke symptom recognition. Lack of education about stroke preparedness and appropriate actions may prevent people from seeking immediate care. Few interventions have rigorously evaluated preparedness strategies in multiethnic community settings. METHODS The Acute Stroke Program of Interventions Addressing Racial and Ethnic Disparities (ASPIRE) project is a multilevel program using a community-engaged approach to stroke preparedness targeted to underserved black communities in the District of Columbia. This intervention aimed to decrease acute stroke presentation times and increase intravenous tissue-type plasminogen activator utilization for acute ischemic stroke. RESULTS Phase 1 included (1) enhancement of focus of emergency medical services on acute stroke; (2) hospital collaborations to implement and enrich acute stroke protocols and transition District of Columbia hospitals toward primary stroke center certification; and (3) preintervention acute stroke patient data collection in all 7 acute care District of Columbia hospitals. A community advisory committee, focus groups, and surveys identified perceptions of barriers to emergency stroke care. Phase 2 included a pilot intervention and subsequent citywide intervention rollout. A total of 531 community interventions were conducted, reaching >10,256 participants; 3289 intervention evaluations were performed, and 19,000 preparedness bracelets and 14,000 stroke warning magnets were distributed. Phase 3 included an evaluation of emergency medical services and hospital processes for acute stroke care and a year-long postintervention acute stroke data collection period to assess changes in intravenous tissue-type plasminogen utilization. CONCLUSIONS We report the methods, feasibility, and preintervention data collection efforts of the ASPIRE intervention. CLINICAL TRIAL REGISTRATION URL http://www.clinicaltrials.gov.
