Background Post-stroke disability is common, costly, and projected to increase. Acute stroke treatments can substantially reduce post-stroke disability, but few patients take advantage of these cost-effective treatments. Practical, cost-efficient, and sustainable interventions to address underutilized acute stroke treatments are currently lacking. In this context, we present the Stroke Ready project, a stepped wedge design, multi-level intervention that combines implementation science and community-based participatory research approaches to increase acute stroke treatments in the predominately African American community of Flint, Michigan, USA. Methods Guided by the Tailored Implementation of Chronic Disease (TICD) framework, we begin with optimization of acute stroke care in emergency departments, with particular attention given to our safety-net hospital partners. Then, we move to a community-wide, multi-faceted, stroke preparedness intervention, with workshops led by peer educators, over 2 years. Measures of engagement of the safety-net hospital and the feasibility and sustainability of the implementation strategy as well as community intervention reach, dose delivered, and satisfaction will be collected. The primary outcome is acute stroke treatment rates, which includes both intravenous tissue plasminogen activator, and endovascular treatment. The co-secondary outcomes are intravenous tissue plasminogen activator treatment rates and the proportion of stroke patients who arrive by ambulance. Discussion If successful, Stroke Ready will increase acute stroke treatment rates through emergency department and community level interventions. The stepped wedge design and process evaluation will provide insight into how Stroke Ready works and where it might work best. By exploring the relative effectiveness of the emergency department optimization and the community intervention, we will inform hospitals and communities as they determine how best to use their resources to optimize acute stroke care.

Background: Black Americans comprise 14% of Michigan’s population, but 30% of the COVID-19 cases and 40% of deaths. The accumulating national quantitative data on decreased presentation and increased pre-hospital delay during the pandemic confirmed our Flint, MI community partners’ impression of a decline in stroke presentations. Thus, we set out to understand the community’s perception of seeking acute stroke care during the pandemic which will inform the development and dissemination of public health messaging in a predominantly Black American community. Method: To honor social distancing orders, we conducted semi-structured interviews based on the Theory of Planned Behavior via HIPAA-approved teleconferencing with community members. Due to the clinical and public health implications of the pandemic, we employed a rapid assessment approach to streamline qualitative data analysis. Results were used to inform the creation of a music video. Lyrics were written by the academic team, set to a soundtrack and sung by a community partner. The music video theme was conceptualized by the academic team and performed by both academic and community partners. Results: We reached thematic saturation after completing 15 semi-structured interviews with Flint, MI community members. Mean duration of interviews was 40 minutes. Eighty percent of participants were Black; median age was 50; 74% were women and 47% reported some college or above. There was an unfavorable attitude towards seeking emergent stroke care via ambulance and at the hospital, due to concerns for viral transmission at the hospital, hospital capacity and ability to triage, and quality of care. Community and academic partners co-created a music video with verses addressing the community-identified barriers: “ stroke is an emergency all the time, even with COVID-19 / get to the hospital as soon as symptoms start, it’s so important to do your part, be Stroke Ready” (https://youtu.be/lKefAiUM2W0) The video reached over 1,200 users on our community-academic partner Stroke Ready Facebook page. Conclusion: We found that community members’ attitudes and perceived behavioral control to seek emergent stroke care were impacted during the COVID-19 pandemic. We addressed these barriers in an academic-community partner created music video. Academic and community partnerships facilitated a timely, innovative response to seeking acute stroke care in the setting of the COVID-19 pandemic.

Background Audit and feedback (A&F) is a widely used implementation strategy. Understanding mechanisms of action of A&F increases the likelihood that the strategy will lead to implementation of an evidence-based practice. We therefore sought to understand one hospital’s experience selecting and implementing an A&F intervention, to determine the implementation strategies that were used by staff and to specify the mechanism of action of those implementation strategies using causal pathway models, with the ultimate goal of improving acute stroke treatment practices. Methods We selected an A&F strategy in a hospital, initially based on implementation determinants and staff consideration of their performance on acute stroke treatment measures. After 7 months of A&F, we conducted semi-structured interviews of hospital providers and administrative staff to understand how it contributed to implementing guideline-concordant acute stroke treatment (medication named tissue plasminogen activator). We coded the interviews to identify the implementation strategies that staff used following A&F and to assess their mechanisms of action. Results We identified five implementation strategies that staff used following the feedback intervention. These included (1) creating folders containing the acute stroke treatment protocol for the emergency department, (2) educating providers about the protocol for acute stroke, (3) obtaining computed tomography imaging of stroke patients immediately upon emergency department arrival, (4) increasing access to acute stroke medical treatment in the emergency department, and (5) providing additional staff support for implementation of the protocol in the emergency department. We identified enablement, training, and environmental restructuring as mechanisms of action through which the implementation strategies acted to improve guideline-concordant and timely acute stroke treatment. Conclusions A&F of a hospital’s acute stroke treatment practices generated additional implementation strategies that acted through various mechanisms of action. Future studies should focus on how initial implementation strategies can be amplified through internal mechanisms.

Objective: Acute stroke treatments reduce the likelihood of post-stroke disability, but are vastly underutilized. In this paper, we describe the development, adaptation, and scale-up of the Stroke Ready program – a health behavior theory-based stroke preparedness intervention that addresses underlying behavioral factors that contribute to acute stroke treatment underutilization. Methods: Through a community-based participatory research (CBPR) approach, we conducted needs and determinant assessments, which informed creation and pilot testing of Stroke Ready. Based on these results, we then scaled Stroke Ready to the entire community by greatly expanding the delivery system. Results: The scaled Stroke Ready program is a community-wide stroke preparedness education program consisting of peer-led workshops, print materials, and digital, social, and broadcast media campaigns. Whereas the Stroke Ready pilot workshop was delivered to 101 participants, 5945 participants have received the scaled Stroke Ready peer-led workshop to date. Additionally, we have sent mailers to over 44,000 households and reached approximately 35,000 people through our social media campaign. Conclusion: Strategies including an expanded community advisory board, adaptation of the intervention and community-engaged recruitment facilitated the scale-up of Stroke Ready, which may serve as a model to increase acute stroke treatment rates, particularly in majority African-American communities.
