Association of the Stroke Ready Community-Based Participatory Research Intervention With Incidence of Acute Stroke Thrombolysis in Flint, Michigan

Importance

Acute stroke treatment rates in the US lag behind those in other high-income nations.

Objective

To assess whether a hospital emergency department (ED) and community intervention was associated with an increased proportion of patients with stroke receiving thrombolysis.

Design, Setting, and Participants

This nonrandomized controlled trial of the Stroke Ready intervention took place in Flint, Michigan, from October 2017 to March 2020. Participants included adults living in the community. Data analysis was completed from July 2022 to May 2023.

Intervention

Stroke Ready combined implementation science and community-based participatory research approaches. Acute stroke care was optimized in a safety-net ED, and then a community-wide, theory-based health behavior intervention, including peer-led workshops, mailers, and social media, was conducted.

Main Outcomes and Measures

The prespecified primary outcome was the proportion of patients hospitalized with ischemic stroke or transient ischemic attack from Flint who received thrombolysis before and after the intervention. The association between thrombolysis and the Stroke Ready combined intervention, including the ED and community components, was estimated using logistic regression models, clustering at the hospital level and adjusting for time and stroke type. In prespecified secondary analyses, the ED and community intervention were explored separately, adjusting for hospital, time, and stroke type.

Results

In total, 5970 people received in-person stroke preparedness workshops, corresponding to 9.7% of the adult population in Flint. There were 3327 ischemic stroke and TIA visits (1848 women [55.6%]; 1747 Black individuals [52.5%]; mean [SD] age, 67.8 [14.5] years) among patients from Flint seen in the relevant EDs, including 2305 in the preintervention period from July 2010 to September 2017 and 1022 in the postintervention period from October 2017 to March 2020. The proportion of thrombolysis usage increased from 4% in 2010 to 14% in 2020. The combined Stroke Ready intervention was not associated with thrombolysis use (adjusted odds ratio [OR], 1.13; 95% CI, 0.74-1.70; P = .58). The ED component was associated with an increase in thrombolysis use (adjusted OR, 1.63; 95% CI, 1.04-2.56; P = .03), but the community component was not (adjusted OR, 0.99; 95% CI, 0.96-1.01; P = .30).

Conclusions and Relevance

This nonrandomized controlled trial found that a multilevel ED and community stroke preparedness intervention was not associated with increased thrombolysis treatments. The ED intervention was associated with increased thrombolysis usage, suggesting that implementation strategies in partnership with safety-net hospitals may increase thrombolysis usage.

Extending Advance Care Planning to Black Americans in the Community: A Pilot Study of the PREPARE Program

CONTEXT

Advance care planning (ACP) is underutilized, especially among Black Americans. Yet, no ACP interventions have been tested at the community level.

OBJECTIVES

Within an established academic and community partnership, we sought to determine whether ACP is a community-identified need and if so, to conduct a pilot study of an evidence-based ACP program, PREPARE (PrepareForYourCare.org).

METHODS

We conducted open discussions and in-depth interviews to determine the relevance of ACP to the community. We then conducted a pre- to 3-week postpilot study of a virtual peer facilitated brief session to introduce ACP and encourage participants to engage with PREPARE. We conducted thematic content analysis for qualitative data and used paired t-tests to assess within-participant changes in the validated ACP Engagement Survey measured on a 1-5 scale (5 = greatest engagement).

RESULT

We conducted two discussion groups with community leaders (n = 12) and key informant interviews (n = 6), including leaders in aging, public health, health care and faith. We concluded that ACP is a community priority. In the pilot study, we enrolled 13 Black Americans; 85% were women and the mean age was 59.7 years (SD 15.1). There was a trend toward increased ACP engagement after the peer facilitated PREPARE (mean 3.2 (SD 0.6) pre vs. 3.5 (SD 0.6) post, paired t-test P = 0.06). All participants found the intervention to be acceptable and were satisfied with it.

CONCLUSION

Community members identified ACP as important for their community. Peer facilitated PREPARE program is a promising community-based strategy to increase engagement in ACP and may promote health equity.

A step toward understanding the mechanism of action of audit and feedback: a qualitative study of implementation strategies

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.

Understanding and Informing Community Emergency Cardiovascular Disease Preparedness during the COVID-19 Pandemic: Stroke Ready

Introduction

Acute stroke and acute myocardial infarction (AMI) treatments are time sensitive. Early data revealed a decrease in presentation and an increase in pre-hospital delay for acute stroke and AMI during the coronavirus disease 2019 (COVID-19) pandemic. Thus, we set out to understand community members’ perception of seeking acute stroke and AMI care during the COVID-19 pandemic to inform strategies to increase cardiovascular disease preparedness during the pandemic.

Methods

Given the urgency of the clinical and public health situation, through a community-based participatory research partnership, we utilized a rapid assessment approach. We developed an interview guide and data collection form guided by the Theory of Planned Behavior (TPB). Semi-structured interviews were recorded and conducted via phone and data was collected on structured collection forms and real time transcription. Direct content analysis was conducted guided by the TPB model and responses for AMI and stroke were compared.

Results

We performed 15 semi-structured interviews. Eighty percent of participants were Black Americans; median age was 50; 73% were women. Participants reported concerns about coronavirus transmission in the ambulance and at the hospital, hospital capacity and ability to triage, and quality of care. Change in employment and childcare also impacted participants reported control over seeking emergent cardiovascular care. Based on these findings, our community and academic team co-created online materials to address the community-identified barriers, which has reached over 8,600 users and engaged almost 600 users.

Conclusions

We found that community members’ attitudes and perceived behavioral control to seek emergent cardiovascular care were impacted by the COVID-19 pandemic. Community-informed, health behavior theory-based public health messaging that address these constructs may decrease prehospital delay.

Development, Adaptation and Scale-up of a Community-wide, Health Behavior Theory-based Stroke Preparedness Intervention

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.

Expanding Stroke Preparedness to Vulnerable Populations: A Music Video for the Deaf Community

Background

Acute stroke treatments reduce disability after stroke, but eligibility for these treatments depends on rapid hospital arrival after symptom onset. Stroke preparedness interventions teach stroke symptoms and the importance of calling 911, thereby increasing patient eligibility for stroke treatments. Stroke preparedness interventions for the Deaf community are lacking. We sought to adapt a stroke preparedness music video, which was initially created for the hearing, for the Deaf community.

Methods and Results

We used a community‐engaged approach, partnering with members of the Deaf community, to adapt the video over 4 months. Adaptation involved assessing the comprehensibility and appropriateness of the video and interpreting the song lyrics into American Sign Language.

Conclusions

We collaborated with the Deaf community to create a stroke preparedness video for the Deaf. Future research will involve refining the video and testing its efficacy to increase stroke symptom recognition and intent to call 911.

Stroke Ready: a multi-level program that combines implementation science and community-based participatory research approaches to increase acute stroke treatment: protocol for a stepped wedge trial

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.
