Stroke Ready Intervention: Community Engagement to Decrease Prehospital Delay.

ABSTRACT: BACKGROUND:Time-limited acute stroke treatments are underused, primarily due to prehospital delay. One approach to decreasing prehospital delay is to increase stroke preparedness, the ability to recognize stroke, and the intention to immediately call emergency medical services, through community engagement with high-risk communities. METHODS AND RESULTS:Our community-academic partnership developed and tested "Stroke Ready," a peer-led, workshop-based, health behavior intervention to increase stroke preparedness among African American youth and adults in Flint, Michigan. Outcomes were measured with a series of 9 stroke and nonstroke 1-minute video vignettes; after each video, participants selected their intended response (primary outcome) and symptom recognition (secondary outcome), receiving 1 point for each appropriate stroke response and recognition. We assessed differences between baseline and posttest appropriate stroke response, which was defined as intent to call 911 for stroke vignettes and not calling 911 for nonstroke, nonemergent vignettes and recognition of stroke. Outcomes assessments were performed before workshop 1 (baseline), at the conclusion of workshop 2 (immediate post-test), and 1 month later (delayed post-test). A total of 101 participants completed the baseline assessment (73 adults and 28 youths), 64 completed the immediate post-test, and 68 the delayed post-test. All participants were African American. The median age of adults was 56 (interquartile range 35-65) and of youth was 14 (interquartile range 11-16), 65% of adults were women, and 50% of youths were women. Compared to baseline, appropriate stroke response was improved in the immediate post-test (4.4 versus 5.2, P<0.01) and was sustained in the delayed post-test (4.4 versus 5.2, P<0.01). Stroke recognition did not change in the immediate post-test (5.9 versus 6.0, P=0.34), but increased in the delayed post-test (5.9 versus 6.2, P=0.04). CONCLUSIONS:Stroke Ready increased stroke preparedness, a necessary step toward increasing acute stroke treatment rates. CLINICAL TRIAL REGISTRATION:URL: https://www.clinicaltrials.gov/.

Project description:ImportanceAcute stroke treatment rates in the US lag behind those in other high-income nations.ObjectiveTo 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 participantsThis 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.InterventionStroke 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 measuresThe 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.ResultsIn 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 relevanceThis 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.Trial registrationClinicalTrials.gov Identifier: NCT036455900.

Project description:IntroductionStroke is the leading cause of death and disability in China. The median time of stroke pre-hospital delay is more than 15 hours, mainly due to the lack of awareness on stroke symptoms and calling emergency services. We developed Stroke 1-2-0 recognition tool in China, by adapting Face, Arm, Speech and Time. Our preliminary findings suggested that Stroke 1-2-0 can improve public's knowledge of the stroke symptoms, but its impact on the prehospital delay is still unclear. Furthermore, these findings were mainly obtained from Shanghai, one of the largest metropolises in China. However, more than half of population in China lives in the rural area. Given the striking disparities in socioeconomic status and quality of stroke care across the nation, a multicentre trial is warranted.Methods and analysisStroke 1-2-0 education programme will adopt a multicentre, cluster-randomised controlled design. We aimed to recruit 32 communities from 16 counties across China. Each county includes two communities having more than 100 000 residents. The two communities sampled in the same county will be randomly assigned to receive either Stroke 1-2-0 education programme or usual care. The primary objective of this study is to evaluate the impact of Stroke 1-2-0 public education programme in reducing stroke prehospital delay among adults residing in the community, compared with the usual care. The intervention will be implemented for 1 year. The primary outcomes are the symptom onset to hospital arrival time ('onset-to-door time', ODT) and 3-hour hospital arriving rate. We will use an intention-to-treat approach. A linear mixed model will be used to control for potential cluster effects.Ethics and disseminationThis study is approved by the Shanghai Minhang District Central Hospital Institutional Review Board (Shanghai, China). The findings will be disseminated via peer-reviewed publications and conference presentations.Trial registration numberChiCTR2000040782.

Project description:BACKGROUND:Acute ischemic stroke (AIS) is a medical emergency. The outcome is closely linked to the time elapsing from symptom onset to treatment, and seemingly small delays can mean the difference between full recovery and physical and cognitive dysfunction. Recanalization to allow blood to reenter the affected area is most efficient immediately after symptoms occur, and intravenous thrombolysis must be initiated no later than 4.5 hours after the symptom onset. A liable diagnosis is mandatory to administer the appropriate treatment. Prehospital diagnosis and, in cases where contraindications are ruled out, prehospital initiation of intravenous thrombolysis have been shown to significantly decrease the time from alarm to the treatment. OBJECTIVE:The objective of this paper is to investigate the effectiveness of prehospital thrombolysis as measured by (1) time spent from symptom onset to treatment and (2) the number of patients treated within 4.5 hours. In addition, we want to conduct explorative studies. These will include (1) the use of biomarkers for diagnostic and prognostic use where we will collect blood samples from various time points, including the hyperacute phase and (2) the study of magnetic resonance imaging (MRI) images at day 1 to determine the infarct volume and if the time to thrombolysis has an influence on this. METHODS:This is a prospective controlled intervention study. The intervention will involve a computed tomography (CT) and thrombolysis in a physician-manned ambulance called a mobile stroke unit (MSU). The control will be the conventional pathway where the patient is transported to the hospital for CT, and thrombolysis as per current procedure. RESULTS:Patient inclusion has started and a total of 37 patients are enrolled (control and intervention combined). The estimated time to completed inclusion is 36 months, starting from May 2017. The results of this study will be analyzed and published at the end of the trial. CONCLUSIONS:This trial aims to document the feasibility of saving time for all stroke patients by providing prehospital diagnostics and treatment, as well as transport to appropriate level of care, in a safe environment provided by anesthesiologists trained in prehospital critical care.
