Stroke education: discrepancies among factors influencing prehospital delay and stroke knowledge

Analyzing prehospital delays in recurrent acute ischemic stroke: Insights from interpretable machine learning

OBJECTIVE

This study investigates prehospital delays in recurrent Acute Ischemic Stroke (AIS) patients, aiming to identify key factors contributing to these delays to inform effective interventions.

METHODS

A retrospective cohort analysis of 1419 AIS patients in Shenzhen from December 2021 to August 2023 was performed. The study applied the Extreme Gradient Boosting (XGBoost) algorithm and SHapley Additive exPlanations (SHAP) for identifying determinants of delay.

RESULTS

Living with others and lack of stroke knowledge emerged as significant risk factors for delayed hospital presentation in recurrent AIS patients. Key features impacting delay times included residential status, awareness of stroke symptoms, presence of conscious disturbance, diabetes mellitus awareness, physical weakness, mode of hospital presentation, type of stroke, and presence of coronary artery disease.

CONCLUSION

Prehospital delays are similarly prevalent among both recurrent and first-time AIS patients, highlighting a pronounced knowledge gap in the former group. This discovery underscores the urgent need for enhanced stroke education and management.

PRACTICE IMPLICATION

The similarity in prehospital delay patterns between recurrent and first-time AIS patients emphasizes the necessity for public health initiatives and tailored educational programs. These strategies aim to improve stroke response times and outcomes for all patients.

Stroke signs knowledge and factors associated with a delayed hospital arrival of patients with acute stroke in Kinshasa

Background

Rapid recognition and early medical intervention are essential to reduce stroke-related mortality and long-term disability. This study aimed to evaluate awareness of stroke symptoms/signs and determine factors delaying the hospital arrival of patients with acute stroke in Kinshasa.

Methods

Patients with stroke and/or accompanying family members were interviewed using a standard questionnaire, and their medical records were reviewed. Factors independently associated with a late arrival (≥4.5 h) to the hospital were identified using the logistic regression test in forward multivariate analysis.

Results

Overall, 202 patients with an average age of 57.9 ± 13.1 years were included. Only 27 (13.4%) patients immediately associated the initial symptoms with a stroke episode. Delayed hospital arrival was observed in 180 (89.1%) patients. Unmarried status (adjusted odds ratio [aOR], 2.29; 95% confidence interval [CI], 1.17-4.88; p = 0.007), low education level (aOR, 2.29; 95% CI, (1.12-5.10; p = 0,014), absence of impaired consciousness (aOR, 3.12; 95% CI, 1.52-4.43; p = 0.005), absence of a history of hypertention (aOR, 1.85; 95% CI, 1.18-3.78; p = 0.041), absence of a history of diabetes (aOR, 1.93; 95% CI, 1.15-4.58; p = 0.013), heavy alcohol consumption (aOR, 1.83; 95% CI, 1.12-2.83; p = 0.045), absence of a severe to very severe stroke (aOR, 4.93; 95% CI, 0.82-1.01; p = 0.002), and presence of ischemic stroke (aOR, 2.93; 95% CI, 1.54-4.59; p = 0.001) were identified as independent determinants of delayed hospital arrival.

Conclusions

This study depicted a low stroke awareness rate and a much longer prehospital delay than evidence-based guidelines recommend and identified eight factors that public health actions could target to promote the earliest management of stroke.

Healthcare-Seeking Delays in Acute Ischemic Stroke Patients: The Influence of Gender, Immigrant Status, and Educational Background

Purpose

Timely medical attention is crucial for patients with Acute Ischemic Stroke (AIS), as delays can significantly impact therapeutic outcomes. These delays are influenced by a combination of socio-cultural, educational, and clinical factors.

Patients and Methods

An in-depth analysis was conducted to assess the prevalence and median duration of healthcare-seeking delays in AIS patients. The study specifically investigated the independent impacts of sociocultural and clinical determinants on these delays, with a focus on immigrant status, gender disparities, and educational levels. Multivariate regression analysis was employed to identify these independent effects while controlling for potential confounding factors.

Results

Among 1419 AIS patients, 82.52% (n = 1171) experienced delays exceeding 2 hours from symptom onset of symptoms to hospital arrival. The median delay was 12.3 hours. Immigrant populations encountering longer delays compared to native groups. Younger males (<45 years) and elderly females were more prone to delay in healthcare-seeking. Identified independent risk factors for delay included male gender (OR = 1.65 [95% CI:1.14-2.48]), self-acknowledged diabetes (OR = 2.50 [95% CI:1.21-5.17]), small vessel (OR = 2.07 [95% CI:1.27-3.36]), and wake stroke (OR = 7.04 [95% CI:3.69-13.44]). Educational background (high school and above), GCS score with 3-8 points (OR = 0.52 [95% CI:0.09-0.69]), understanding stroke-related knowledge (OR = 0.26 [95% CI:0.09-0.44]), conscious disturbance (OR = 0.25 [95% CI:0.10-0.62]) and limb weakness (OR=0.21[95% CI:0.21-0.49]) are protective factors for timely treatment.

Conclusion

Immigrant populations experienced longer delays from symptom onset to hospital arrival. The crucial roles of education and knowledge about stroke underscore the need for enhanced health literacy campaigns and public awareness, with a targeted focus on younger males and elderly females.

Mediation Analyses of the Mechanisms by Which Socioeconomic Status, Comorbidity, Stroke Severity, and Acute Care Influence Stroke Outcome

BACKGROUND AND OBJECTIVES

Low socioeconomic status (SES) is associated with increased risk of death and disability after stroke, but interventional targets to minimize disparities remain unclear. We aim to assess the extent to which SES-based disparities in the association between low SES and death and dependency at 3 months after stroke could be eliminated by offsetting differences in comorbidity, stroke severity, and acute care.

METHODS

This nationwide register-based cohort study included all 72 hospitals caring for patients with acute stroke in Sweden. All patients registered with an acute ischemic stroke in the Swedish Stroke Register in 2015-2016 who were independent in activities of daily living (ADL) during stroke were included. Data on survival and SES the year before stroke were retrieved by cross-linkage with other national registers. SES was defined by education and income and categorized into low, mid, and high. Causal mediation analysis was used to study the absolute risk of death and ADL dependency at 3 months depending on SES and to what extent hypothetical interventions on comorbidities, stroke severity, and acute care would equalize outcomes.

RESULTS

Of the 25,846 patients in the study, 6,798 (26.3%) were dead or ADL dependent 3 months after stroke. Adjusted for sex and age, low SES was associated with an increased absolute risk of 5.4% (95% CI 3.9%-6.9%; p < 0.001) compared with mid SES and 10.1% (95% CI 8.1%-12.2%; p < 0.001) compared with high SES. Intervening to shift the distribution of all mediators among patients with low SES to those of the more privileged groups would result in absolute reductions of these effects by 2.2% (95% CI 1.2%-3.2%; p < 0.001) and 4.0% (95% CI 2.6%-5.5%; p < 0.001), respectively, with the largest reduction accomplished by equalizing stroke severity.

DISCUSSION

Low SES patients have substantially increased risks of death and ADL dependency 3 months after stroke compared with more privileged patient groups. This study suggests that if we could intervene to equalize SES-related differences in the distributions of comorbidity, acute care, and stroke severity, up to 40 of every 1,000 patients with low SES could be prevented from dying or becoming ADL dependent.

Most patients with an increased risk for sepsis-related morbidity or death do not recognize sepsis as a medical emergency: results of a survey study using case vignettes

BACKGROUND

Sepsis is a medical emergency with potentially life-threatening consequences. Patients play a crucial role in preventing and recognizing sepsis at an early stage. The understanding of risk groups' sepsis knowledge and their ability to use this knowledge to recognize sepsis as an emergency is incomplete.

METHODS

We conducted a cross-sectional survey in Germany and included a sample of 740 persons stratified by age (< 60 years,  ≥ 60 years), specific chronic diseases (e.g. diabetes, chronic diseases, cancer), and region (Berlin/Brandenburg vs. other federal states of Germany). Standardized questionnaires were administered by a market research institute through online, telephone, or face-to-face methods. We assessed sepsis knowledge through a series of questions and the ability to recognize sepsis as an emergency through five case vignettes. To identify predictors of sepsis knowledge and the ability to recognize sepsis as a medical emergency, we conducted multiple linear regressions.

RESULTS

Of the 36 items on sepsis knowledge, participants answered less than 50 per cent correctly (mean 44.1%; standard deviation (SD) 20.1). Most patients knew that sepsis is a defensive host response to infection (75.9%), but only 30.8% knew that vaccination can prevent infections that lead to sepsis. Across the five vignettes, participants identified sepsis as an emergency in only 1.33 of all cases on average (SD = 1.27). Sepsis knowledge was higher among participants who were older, female, and more highly educated and who reported more extensive health information seeking behaviour. The ability to recognize sepsis as an emergency was higher among younger participants, participants without chronic diseases, and participants with higher health literacy, but it was not significantly associated with sepsis knowledge.

CONCLUSIONS

Risk groups showed low levels of knowledge regarding the preventive importance of vaccination and a low ability to recognize sepsis as a medical emergency. Higher levels of sepsis knowledge alone were not sufficient to improve the ability to identify sepsis as a medical emergency. It is crucial to develop effective educational strategies-especially for persons with lower education levels and infrequent health information seeking behaviour-that not only transfer but also facilitate the choice of appropriate actions, such as seeking timely emergency care.

Relationship of family function and pre-hospital delay among Chinese patients with recurrent ischaemic stroke and the mediation effect of stigma

AIMS

Pre-hospital delay refers to the time span from the onset of symptoms to arrival at a hospital ≥ 3 h and is the main limitation of stroke reperfusion therapies. Family factors and stroke-related stigma may influence pre-hospital delay. However, few studies have confirmed the influence of stigma on pre-hospital delay or explored the relationships between family function, stigma, and pre-hospital delay among patients with recurrent stroke. This study aimed to explore the relationship between family function and pre-hospital delay among patients with recurrent stroke and examine the mediation role of stigma in this relationship.

METHODS AND RESULTS

A cross-sectional study was performed at the neurology departments of two hospitals in Guangzhou, China between July 2021 and April 2022. A total of 115 patients with recurrent stroke completed questionnaires and were included in the analysis. Data were collected using the Short Form Family Assessment Device, the Stroke Stigma Scale, and the Stroke Knowledge Questionnaire. Spearman's correlation and a structural equation model were used for data analysis. Family function directly influenced pre-hospital delay [β=0.27, P = 0.033, 95%CI = (0.02-0.51)] and indirectly influenced pre-hospital delay [β=0.17, P = 0.038, 95%CI = (0.02-0.34)] through stigma. Moreover, stigma partially mediated the effect of family function on pre-hospital delay.

CONCLUSION

Family function and stigma directly and indirectly influenced pre-hospital delay among patients with recurrent stroke. Future health education and interventions need to focus on strengthening and improving emotional support from family members to improve family function and reduce stigma, thereby reducing pre-hospital delay among patients with recurrent stroke.

Recognition, reaction, risk factors and adequate knowledge of stroke: A Brazilian populational survey

INTRODUCTION

General population proper knowledge about stroke can improve stroke outcomes. We aimed to assess the awareness levels of laypeople regarding stroke recognition, reaction, risk factors, and adequate general knowledge (correct answers for those three questions) of stroke.

METHODS

Cross-sectional survey-based study enrolling community population from 12 cities of Brazil's Northeast. The volunteers were verbally exposed to a typical case of stroke and then responded to an open-ended semi-structured questionnaire to evaluate their stroke knowledge.

RESULTS

A total of 1475 subjects enrolled in this study (52.6% of women, mean±SD 36.2±15.3 years-old, 13.0±4.4 years of formal schooling). 1220/1475 (82.7%) recognized the situation as a stroke; 1148/1475 (77.8%) would react to it by taking the patient to the emergency department or calling for emergency medical assistance; 844/1475 (57.2%) knew at least one risk factor; and 190/1475 (12.9%) stated that symptoms could be reversed if the patient was treated "as soon as possible". Adequate general knowledge was found in 622/1475 (42,2%) of participants. Notably, among those who recognized the stroke, 19.9% (243/1220) would not react appropriately to it. The multivariate analysis showed that factors independently related to stroke recognition were female sex, higher education levels, private health insurance and previous experience with a similar situation. Adequate general knowledge was associated with longer school years and health insurance.

CONCLUSIONS

The frequency of stroke recognition and appropriate reaction were acceptable, however the general knowledge, knowledge of risk factors and notion that stroke treatment is time-sensitive were insufficient. Addressing the recognition-reaction gap requires targeted campaigns focusing on stroke treatment awareness.

Effectiveness of a digital application to improve stroke knowledge for kids

INTRODUCTION

Stroke is highly prevalent in Latin America and one of the leading causes of morbidity and mortality in the world. Educating children about stroke has been established as an effective method to detect symptoms early, reduce hospital visits, and raise awareness among adults.

OBJECTIVE

To analyze the effectiveness of a mobile application to improve knowledge and understanding of stroke among children.

METHOD

We conducted a focus group session including 12 children in order to analyze the behavior of 6 questions previously validated by expert neurologists. Subsequently, 105 primary school students between the ages of 7 and 12 completed a questionnaire on stroke symptoms and how to contact the emergency services before and after using an application on stroke symptoms. Qualitative analyses and the Student t test were used to verify the existence of differences between pre- and post-intervention test results.

RESULTS

After a single 40-min working session with the application, between 50% and 67% of the children were able to identify the signs of stroke, and 96.2% knew the national emergency services telephone number. Statistical analysis revealed statistically significant differences before and after the intervention with the digital application (t=19.54; p<0.001) and intragroup differences in the post-intervention test results (t=40.71; p<0.001).

CONCLUSION

Primary school children who used our digital application increased their knowledge, understanding, and learning of stroke symptoms.

Influencing factors for decision-making delay in seeking medical care among acute ischemic stroke patients in rural areas

OBJECTIVE

To explore the factors influencing decision-making delay in seeking medical care for patients with acute ischemic stroke (AIS) in rural areas.

METHODS

From September to December 2021, we conducted a questionnaire survey of 260 patients with AIS who were hospitalized in the neurology departments of four county-level hospitals in Daqing. A decision-tree and logistic regression model was used to investigate the elements contributing to decision-making delays.

RESULTS

This study found that the decision-making delay rate for rural patients with AIS was 71.5%. The results of the univariate analysis showed that factors associated with decision-making delay included educational level, National Institute of Health stroke scale (NIHSS) score, self-assessed health, monthly income, social support, attitude toward medical help-seeking, health belief, and family dynamics (P < 0.05). Further, we combined logistic regression (LR) and decision-tree (DT) models for multivariate analysis, and finally obtained five factors affecting decision-making delay in AIS patients in rural areas: disease severity, health belief, monthly income (common factors), educational level (only DT model), and social support (only LR model).

CONCLUSIONS

This study found that a few variables, including disease severity, educational level, monthly income, health belief, and social support, affected rural AIS patients' decision-making delay in seeking medical care.

PRACTICE IMPLICATIONS

To achieve the goal of reducing decision-delay and increasing thrombolysis rate, this study thoroughly examined the influencing factors of decision-making delay in seeking medical care of rural AIS patients from various angles. This analysis provides guidance for medical and healthcare professionals on how to best provide future health education for the high-risk population for stroke in rural areas.

Decision Delay Is a Significant Contributor to Prehospital Delay for Stroke Symptoms

Prehospital delay after stroke symptom onset is a primary barrier to eligibility for reperfusion therapies. Decision delay is an understudied contributor to prehospital delay. We aimed to explore decision delay as a component of prehospital delay. For this correlational study, 170 Thai acute stroke patients were interviewed to explore their treatment-seeking decision factors: prior stroke knowledge, onset context, and cognitive, emotional, and behavioral factors. Participants' mean age was 61.2 years, and 46% were women. Median decision delay and prehospital delay times were 120 and 372 minutes. Decision delay represented 49% of prehospital delays. Factors shortening decision delay were atrial fibrillation, prior stroke knowledge, perceived cause of symptoms as stroke, perceived severity of symptoms, and advice from bystanders to seek treatment. In contrast, seeking support from others and self-treatment affected prolonged decision delay. Shortening decision delay, often under the patient or bystander control, can reduce overall prehospital delay.

Public and outpatients’ awareness of calling emergency medical services immediately by acute stroke in an upper middle-income country: a cross-sectional questionnaire study in greater Gaborone, Botswana

Objectives

In this cross-sectional study from Botswana, we investigated awareness of calling emergency medical services (EMS) and seeking immediate medical assistance by acute stroke among stroke risk outpatients and public.

Method

Closed-ended questionnaires on awareness of calling EMS and seeking immediate medical assistance by acute stroke, were administered by research assistants to a representative selection of outpatients and public.

Results

The response rate was 96.0% (93.0% for public (2013) and 96.6% for outpatients (795)). Public respondents had mean age of 36.1 ± 14.5 years (age range 18–90 years) and 54.5% were females, while outpatients had mean age of 37.4 ± 12.7 years (age range 18–80 years) and 58.1% were females.

Awareness of calling EMS (78.3%), and of seeking immediate medical assistance (93.1%) by stroke attack was adequate. For calling EMS by acute stroke, outpatients had higher awareness than the public (p < 0.05) among those with unhealthy diet (90.9% vs 71.1%), family history of both stroke and heart diseases (90.7% vs 61.2%), no history of psychiatric diseases (93.2% vs 76.0%) and sedentary lifestyle (87.5% vs 74.8%).

Predictors of low awareness of both calling EMS and seeking immediate medical assistance were no medical insurance, residing/working together, history of psychiatric diseases, and normal weight.

Male gender, ≥50 years age, primary education, family history of both stroke and heart diseases, current smoking, no history of HIV/AIDS, and light physical activity were predictors of low awareness of need for calling EMS.

Conclusion

Results call for educational campaigns on awareness of calling EMS and seeking immediate medical assistance among those with high risk factor levels.

Approaches to improving symptom appraisal: a systematic literature review

OBJECTIVES

Poor symptom appraisal (detection, interpretation and response to symptoms) plays a major role in prolonged prediagnosis interval in various health conditions. Theories and models have been proposed to study the symptom appraisal process but how they could be employed to improve symptom appraisal remains unclear. We therefore aimed to review approaches to improving symptom appraisal in the literature and to develop a theoretical framework that could guide the development of approaches to improving symptom appraisal among individuals in the general population.

DESIGN

Systematic review.

DATA SOURCES

Medline, Web of Science, PsycINFO, Embase, CINAHL and Scopus were searched from inception to 30 March 2021.

ELIGIBILITY CRITERIA

We included original articles in English in which approaches to improve the detection, interpretation or response to symptoms for symptomatic individuals were described. We excluded articles in which approaches were developed to improve symptom appraisal among healthcare professionals.

DATA EXTRACTION AND SYNTHESIS

A predefined data extraction form was used to extract the development, characteristics and evaluation of approaches to improving symptom appraisal. This formed the basis for the narrative synthesis.

RESULTS

Of 19 046 publications identified from the literature search, 112 were selected for full-text review and 29 approaches comprising provision of knowledge of symptoms/signs and additional components (eg, symptom self-examination and comparison) for symptom appraisal were included in the synthesis. Less than half (41.4%) of these approaches were developed based on theories/models. Interestingly, despite the variety of theories/models adopted in developing these approaches, the components of these approaches were similar.

CONCLUSION

Symptom appraisal is an essential process in a patient's journey that can be targeted to facilitate early diagnosis but is largely unstudied. Building on the literature, we proposed a theoretical framework and approaches to improving symptom appraisal. This could facilitate early identification of a variety of health conditions in the general population.

Pre-Hospital Delay in Acute Ischemic Stroke Care: Current Findings and Future Perspectives in a Tertiary Stroke Center from Romania-A Cross-Sectional Study

Background and objectives: The time interval between stroke onset and hospital arrival is a major barrier for reperfusion therapies in acute ischemic stroke and usually accounts for most of the onset-to-treatment delay. The present study aimed to analyze the pre-hospital delays for patients with acute ischemic stroke admitted to a tertiary stroke center in Romania and to identify the factors associated with a late hospital arrival. Material and methods: The study population consisted of 770 patients hospitalized with the diagnosis of acute ischemic stroke in the University Emergency Hospital Bucharest during a 6-month period, between 1 January and 30 June 2018. Data regarding pre-hospital delays were prospectively collected and analyzed together with the demographic and clinical characteristics of the patients. Results: In total, 31.6% of patients arrived at the hospital within 4.5 h from stroke onset and 4.4% in time intervals between 4.5 and 6 h from the onset, and 28.7% of the patients reached the hospital more than 24 h after onset of symptoms. Transport to hospital by own means was the only factor positively associated with arrival to hospital > 4.5 h from stroke onset and more than doubled the odds of late arrival. Factors negatively associated with hospital arrival > 4.5 h after stroke onset were prior diagnosis of atrial fibrillation, initial National Institute of Health Stroke Scale (NIHSS) score ≥ 16 points, presence of hemianopsia, facial palsy and sensory disturbance. Factors increasing the odds of hospital arrival after 24 h from stroke onset were living alone and living in rural areas. Conclusions: Almost one in three ischemic stroke patients presenting to our center reaches hospital more than 24 h after onset of symptoms. These findings highlight the need for urgent measures to improve not only stroke awareness but also pre-hospital protocols in order to provide timely and appropriate care for our stroke patients.

Visualizing the Knowledge Domain in Health Education: A Scientometric Analysis Based on CiteSpace

Objectives: This study aimed to visualize the evidence in the global research on health education to better improve the nation’s health literacy and to guide future research. Method: We searched the Web of Science (Core Collection) electronic databases. The search strategies: topic: (“Health Education” OR “Education, Health” OR “Community Health Education” OR “Education, Community Health” OR “Health Education, Community”) AND document: (Article) AND language:(English). Articles of evidence from January 2011 to December 2021 with those words in the title or abstract or keywords will be included in this review. We used the Citespace 5.6.R5 (64-bit) to investigate and determine the thematic patterns, and emerging trends of the knowledge domain, and presented a narrative account of the findings. Result: We analyzed 10,273 eligible articles. It showed that BMC Public Health displays the most prolific journals. Author MARCO PAHOR is highlighted in health education. The University of Sydney has published the most studies about health education. The USA plays an important role in these studies. Specifically, the visualization shows several hotspots: disease prevalence surveys and a specific population of knowledge, attitude and practice surveys, health intervention, chronic and non-communicable management, youth-health action, sexual and reproductive health, and physical activity promotion. Furthermore, document co-citation analysis indicated that there are 10 main clusters, which means the research front in health education. Meanwhile, by the citation detected, COVID-19, has achieved universal health coverage in related studies, however, public health education and the health workforce might be more popular in the coming years. Conclusion: Health education is an effective measure to shift the concept of public health and improve healthy living standards. The present study facilitates an extensive understanding of the basic knowledge and research frontiers that are pivotal for the developmental process of health education and allows scholars to visualize the identification modes and tendencies.

FAST Heroes: Results of Cross-Country Implementation of a Global School-Based Stroke Education Campaign

Background

Educating the at-risk population about stroke symptoms and requirement of calling an ambulance when stroke strikes is challenging. This exploratory cross-country study provides insights to the FAST Heroes educational campaign and outcomes hitherto achieved.

Aims

The primary aim of the study was to measure the transfer of stroke-related knowledge to parents after a global school-based FAST Heroes educational campaign for 5- to 9-year-old children in 14 different countries. The secondary aim was to evaluate parents and teachers' acceptability toward the program.

Methods

The duration of the program was 5 h; 1 h per week, joining face-to-face educational sessions with workbooks, cartoons, web-based learning, and other fun activities. Outcomes were measured before implementation (t1), after implementation (t2), and at 6-month follow-up (t3). Program acceptability and stroke knowledge were evaluated by feedback surveys for teachers and parents.

Results

Worldwide, 4,202 parents completed the program with their children and answered surveys at t1 and t2. They increased their knowledge of three stroke symptoms from 48 to 83% (p &lt; 0.001). All three surveys were completed by 86 parents, who improved their knowledge of stroke symptoms, 55% (t1), 79% (t2), and 94% (t3) (p &lt; 0.001). Overall, the educational messages were successfully passed onward.

Conclusions

Findings confirm the primary aim of the study that is knowledge about stroke transfer well from children to their families through the FAST Heroes program. Second, parents and teachers globally consider the program feasible and worthwhile. The results will inform further rollout of the campaign.

Estimated number of eligible patients for mechanical thrombectomy based on NIHSS and population-based Brest stroke registry

BACKGROUND

Since 2015, mechanical thrombectomy (MT) is indicated as a treatment for patients with large vessel occlusion (LVO) at the acute phase of ischemic stroke. However, the number of stroke patients eligible for MT is poorly known.

OBJECTIVE

The objective of our study was to estimate the number of patients eligible for thrombectomy within the first 24hours of an ischemic stroke, based on the clinical National Institute of Health Stroke Scale (NIHSS).

METHOD

Our study concerned all ischemic strokes which occurred between January 2013 and December 2016 recorded in the population-based Brest Stroke Registry (BSR). Based on positive predictive value and negative predictive value from articles evaluating the performance of a defined NIHSS threshold to identify LVO, we first estimated the frequency of patients with LVO and then the frequency of patients eligible for MT depending on pre-stroke modified Rankin score (mRS). Our results were extrapolated to regions of metropolitan France. Two scenarios were considered: one called "stringent criteria" with mRS ≤1 and one called "real-life" criteria with mRS ≤2.

RESULT

We analyzed data from 2,025 ischemic strokes with symptom onset ≤24hours. No statistical difference between patient characteristics according to the time of hospital admission (≤6H vs. 6-24H) was observed. Based on NIHSS scores, between 23.90% and 44.20% of ischemic strokes admitted within the first six hours had LVO clinical characteristics. Among them, 14.53% to 26.87% met the ``stringent eligibility'' criteria for MT and 16.9 to 31.25% for ``real-life'' criteria. Eligible patients represented 6.32% to 11.70% of all ischemic strokes, irrespective of admission time. In France, 75 to 162 persons per million inhabitants per year were eligible for endovascular therapy, depending on including criteria. Based on activity levels recorded by the French Neuroradiology Society (SFNR) in 2018, the estimated needed increase in MT showed a heterogeneous pattern region-by-region, with the greatest need in Brittany, Pays de la Loire, and Corsica.

CONCLUSION

Based on NIHSS, our study provides coherent information concerning the estimated number of MT procedures to be performed in France: 4,877 to 10,494 ischemic strokes would be eligible each year in metropolitan France compared to the 6,596 thrombectomy procedures actually performed in 2018. Depending on the region, an estimated 10-20% to 90-100% increase in MT activity would be necessary to meet patient needs. These data suggest that there is still room for improvement in thrombectomy activity, particularly in certain regions of France, to allow equal access to MT to the entire French population.

Concept review of regionalized systems of acute care: Is regionalization the next frontier in sepsis care?

Regionalization has become a buzzword in US health care policy. Regionalization, however, has varied meanings, and definitions have lacked contextual information important to understanding its role in improving care. This concept review is a comprehensive primer and summation of 8 common core components of the national models of regionalization informed by text-based analysis of the writing of involved organizations (professional, regulatory, and research) guided by semistructured interviews with organizational leaders. Further, this generalized model of regionalized care is applied to sepsis care, a novel discussion, drawing on existing small-scale applications. This discussion highlights the fit of regionalization principles to the sepsis care model and the actualized and perceived potential benefits. The principal aim of this concept review is to outline regionalization in the United States and provide a roadmap and novel discussion of regionalized care integration for sepsis care.

Disparities in the Outcomes Following Ischemic Stroke Between the Floating Population and Indigenous Population of Shanghai

Background and Purposes: Through this study, we hope to gain more insights into the differences in outcome following an ischemic stroke between the floating population and the indigenous population of Shanghai.

Method: In this retrospective cohort study, we analyzed patients with first-ever acute ischemic stroke who were admitted to a comprehensive stroke center in the Minhang district, Shanghai, from January 1, 2019, to December 31, 2020. All patient's demographic data and medical histories were prospectively collected and they were followed up for at least 3 months. The Indigenous population of Shanghai was defined as patients with an identification number starting with 310. All others were treated as floating population. The primary outcome was defined as an unfavorable prognosis at 3 months, with a modified Rankin Scale (mRS) score above 1. Secondary outcomes included the use of emergency medical service (EMS), 3 h arrival rate, and endovascular therapy in eligible patients. Logistic regression analysis was applied to investigate the differences.

Results: Finally, 698 patients with first-ever acute ischemic stroke were included (with mean age of 65.32 years, 74.6% men). Of these, 302 patients belonged to the floating population group. Indigenous populations with ischemic stroke were older than the floating population (68.26 years vs. 61.47 years, P &lt; 0.001). The floating population was more likely to achieve favorable outcomes at 3 months compared with the indigenous population in multivariable logistic regression analysis [Odds ratio (OR): 0.49, 95% CI: 0.32–0.75, P = 0.001]. The use of EMS, 3 h arrival rate, and the application of endovascular therapy were comparable between the floating population and indigenous population (OR: 0.89, 95% CI: 0.62–1.27, P = 0.519; OR: 0.78, 95% CI: 0.56–1.09, P = 0.14; and OR: 0.82, 95% CI: 0.54–1.26, P = 0.365, respectively).

Conclusion: Compared with the indigenous population, the floating population with the first-ever ischemic stroke was more likely to have a favorable outcome at 3 months.

The side effects of the COVID-19 pandemic on key public health elements - How the global emergency has changed the acute management of myocardial infarction and stroke, the network of cancer care, and assistance to frail individuals

The coronavirus disease 2019 (COVID-19) pandemic is a primary health problem globally. In particular, it has caused troubles even to the advanced health systems of Western countrieswho attempted to limit the spread of the infection and manage patients with severe respiratory distress. However, this sudden contingency has had a much higher cost if we also consider the cost of suspending ordinary clinical care or delays in the emergency pathways of non-COVID-19 patients. Furthermore, the policies applied to contain the contagion have exacerbated the socio-economic disparities of the population and isolated fragile patients, making them subject to clinical relapses or aggravation of chronic diseases. For this reason, the various specialist centers have equipped themselves to guarantee an effective therapeutic path. In this brief review, we have outlined some consequent repercussions on the management of acute and chronic cardiovascular and neurovascular diseases and on oncological treatment. In particular, we have described the effects of the current health reorganization on some acute and time-dependent diseases, such as stroke and acute coronary syndromes, in which therapeutic delay is potentially disabling or fatal. Furthermore, we have focused on cancer treatments, whose essential cornerstones are early screening and follow-up. Finally, the suffering of the local health network has led to a lack of continuity of care in fragile patients, such as psychiatric, marginalized, or multiple comorbid patients.

Mechanical thrombectomy for emergent large vessel occlusion: an Australian primary stroke centre workflow analysis

BACKGROUND

Time to successful reperfusion is a critical prognostic factor for acute ischaemic stroke. Mechanical thrombectomy has become the gold standard treatment for emergent large vessel occlusion stroke. The timely delivery of this highly specialised procedure to patients outside of metropolitan centres presents a dilemma of inequity, with limited workflow data hindering benchmarking and service optimisation.

AIMS

To analyse key stroke treatment time parameters from a primary stroke centre existing in a regional centre within a hub-and-spoke delivery model in Victoria, Australia.

METHODS

Retrospective cohort study of patients transferred from a regional primary stroke centre to a metropolitan comprehensive stroke centre for mechanical thrombectomy between July 2016 and December 2018. Time workflow analysis was conducted from symptom onset to primary stroke centre departure.

RESULTS

A total of 55 patients was included in this study with an average age of 70.2 years. Median National Institutes of Health Stroke Scale score on admission was 13 (interquartile range (IQR) 7-17). Median pre-hospital time was 68 min (IQR 56-137) and median door-in-door-out time was 120.5 min (IQR 98-150), constituting 36.1% and 63.9% of total median time from symptom onset to primary stroke centre departure (188.5 min) respectively. There were no significant differences across observed cohort characteristics under linear regression analysis.

CONCLUSION

Protracted pre-hospital and primary stroke centre workflow times can delay effective treatment for patients with acute ischaemic stroke in regional areas. A systems-level approach to streamlining processes in these key areas is required to bridge this inequity in best practice care.

Patient-reported factors associated with early arrival for stroke treatment

OBJECTIVE

Timely evaluation and initiation of treatment is the key for improving stroke outcomes, although minimizing the time from symptom onset to the first contact with healthcare professionals remains a challenge. We aimed to identify patient-related factors associated with early hospital arrival.

MATERIALS AND METHODS

In this cross-sectional survey, we included patients with stroke or transient ischemic attack admitted directly to one of two noncomprehensive stroke units or transferred to the units from comprehensive stroke centers in the Capital Region of Denmark. Patient-reported factors associated with early hospital arrival were analyzed using multivariable logistic regression analysis adjusted for age, sex, education, living arrangement, brain location of the stroke, stroke severity, patient-perceived symptom severity, history of prior stroke, stroke risk factors, and knowledge of stroke symptoms.

RESULTS

In total, 479 patients with acute stroke were included (median age 74 (25th-75th percentile, 64-80), 40% women), of whom 46.4% arrived within 180 min of symptom onset. Factors associated with early hospital arrival were patients or bystanders choosing emergency medical service (EMS) for the first contact with a medical professional (adjusted odds ratio (OR), 3.41; 95% confidence interval, CI [1.57, 7.35]) or the patient's perceived symptom severity above the median score of 25 on a 100-point verbal scale (adjusted OR, 2.44; 95% CI [1.57, 3.82]). Living alone reduced the likelihood of early arrival (adjusted OR, 0.53; 95% CI [0.33, 0.86]).

CONCLUSIONS

Only when patients perceived symptoms as severe or when EMS was selected as the first contact, early arrival for stroke treatment was ensured.

Pre-hospital causes for delayed arrival in acute ischemic stroke before and during the COVID-19 pandemic: A study at two stroke centers in Egypt

BACKGROUND

In the current study we investigated the causes of pre-hospital delay as this can compromise the patient's chance to receive thrombolytic therapy and thus impact stroke outcome.

METHODS

We surveyed 254 patients regarding reasons for delayed and early arrival to hospital after acute ischemic stroke. The survey was performed over five months, spanning a period pre- and during COVID-19 (between December 7, 2019 and May 10, 2020).

RESULTS

A total of 71.2% of patients arrived beyond four hours of onset of ischemic stroke. The commonest cause for delay pre-Covid-19 was receiving treatment in a non-stroke hospital, while that during COVID-19 was fear of infection and lock down issues. Not realizing the urgency of the condition and stroke during sleep were common in both periods. Early arrival because of the patient's previous experience with stroke accounted for approximately 25% of cases in both periods. The effect of media was more evident during COVID-19, accounting for 47.7% of cases.

CONCLUSION

Pre-hospital delay secondary to misperception of the urgency of stroke and management in a non-stroke hospital reflect the lack of awareness among the public and medical staff. This concept is emphasized by early arrival secondary to previous experience with stroke and the pronounced effect of media in the time of COVID-19.

Pitfalls in the Diagnosis of Posterior Circulation Stroke in the Emergency Setting

Posterior circulation stroke (PCS), caused by infarction within the vertebrobasilar arterial system, is a potentially life-threatening condition and accounts for about 20–25% of all ischemic strokes. Diagnosing PCS can be challenging due to the vast area of brain tissue supplied by the posterior circulation and, as a consequence, the wide range of—frequently non-specific—symptoms. Commonly used prehospital stroke scales and triage systems do not adequately represent signs and symptoms of PCS, which may also escape detection by cerebral imaging. All these factors may contribute to causing delay in recognition and diagnosis of PCS in the emergency context. This narrative review approaches the issue of diagnostic error in PCS from different perspectives, including anatomical and demographic considerations as well as pitfalls and problems associated with various stages of prehospital and emergency department assessment. Strategies and approaches to improve speed and accuracy of recognition and early management of PCS are outlined.

Ischemic stroke in Morocco: Prehospital delay and associated factors

OBJECTIVES

This study aimed to estimate prehospital delay and to identify the factors associated with the late arrival of patients with ischemic stroke at the Souss Massa Regional Hospital Center in Morocco.

PATIENTS AND METHODS

An observational, prospective, cross-sectional study was conducted from March 2019 to September 2019 in the Souss Massa regional hospital center, which is a public hospital structure. A questionnaire was administered to patients with ischemic stroke and to bystanders (family or others), while clinical and paraclinical data were collected from medical records. Univariate and multivariate logistic regression analyses were used to identify the factors associated with delayed arrival at emergency department.

RESULTS

A total of 197 patients and 197 bystanders who fulfilled the criteria for the study were included. The median time from symptom onset to hospital arrival was 6hours (IQR, 4-16). Multiple regression analysis showed that illiteracy (OR 38.58; CI_95%: 3.40-437.27), waiting for symptoms to disappear (patient behavior) (OR 11.24; CI_95%: 1.57-80.45), deciding to go directly to the hospital (patient behavior) (OR 0.07; CI_95%: 0.01-0.57), bystander's knowledge that stroke is a disease requiring urgent care within a limited therapeutic window (OR 0.005; CI_95%: 0.00-0.36), and direct admission without reference (OR 0.005; CI_95%: 0.00-0.07), were independently associated with late arrival (>4.5hours) of patients with acute ischemic stroke. In addition, illiteracy (OR 24.62; CI_95%: 4.37-138.69), vertigo and disturbance of balance or coordination (OR 0.14; CI_95%: 0.03-0.73), the relative's knowledge that stroke is a disease requiring urgent care and within a limited therapeutic window (OR 0.03; CI_95%: 0.00-0.22), calling for an ambulance (relative's behavior) (OR 0.16; CI_95%: 0.03-0.80), distance between 50 and 100km (OR 10.16; CI_95%: 1.16-89.33), and direct admission without reference (OR 0.03; CI_95%: 0.00-0.14), were independently associated with late arrival (>6hours) of patients with acute ischemic stroke.

CONCLUSION

Patient behavior, bystander knowledge and direct admission to the competent hospital for stroke care are modifiable factors potentially useful for reducing onset-to-door time, and thereby increasing the implementation rates of acute stroke therapies.

Stroke patient's alarm choice: General practitioner or emergency medical services

Objectives

Stroke patients should be treated as soon as possible since the benefit of reperfusion therapies is highly time‐dependent. The proportion of patients eligible for reperfusion therapy is still limited, as many patients do not immediately alarm healthcare providers. The choice of healthcare system entrance influences the time of arrival in the hospital. Therefore, we assessed differences in these choices to obtain insight for strategies to reduce time delays in acute stroke patients.

Materials and Methods

Patients with suspected acute stroke admitted to the participating hospitals received a questionnaire. We assessed differences between patients who initially alarmed the general practitioner (GP) and patients who directly alarmed the emergency medical services (EMS). Additionally, we assessed regional differences and patient trajectories after medical help was sought.

Results

We included 163 patients. Most patients alarmed the GP as primary healthcare provider (n = 104; 64%), and median onset‐to‐door times were longer in these patients (466 minutes [IQR 149–1586]) compared to patients directly alarming the EMS (n = 59; 36%) (90 minutes [IQR 45–286]). This was even more pronounced in less densely populated areas. Patients who alarmed the GP first, more often had patient delay >15 minutes, hesitated to burden healthcare providers and underestimated symptomatology.

Conclusions

Our results showed that patients who alarmed the GP first instead of the EMS differed in several factors that are potentially modifiable. Strategies to achieve reduction of vital prehospital time delays and to improve patient outcome are optimizing public awareness campaigns and GP triage along with adjusting current guidelines by enabling and focusing on immediate involvement of the EMS once acute stroke is suspected.

Comparative Evaluation of Stroke Awareness of Individuals Whose First-Degree Relatives had a Stroke and that of Individuals Whose First-Degree Relatives Did Not

OBJECTIVE

To assess the stroke awareness levels of individuals whose first-degree relatives had a stroke and to compare the results with those of individuals whose first-degree relatives did not have a stroke.

MATERIALS AND METHODS

This cross-sectional study was conducted between March and May 2019, with first-degree relatives of patients who had a stroke (group 1) and a comparable set of individuals whose first-degree relatives did not have a stroke (group 2). Participants were asked to complete a questionnaire asking about signs and symptoms, risk factors, treatment options, information sources, responses after the development of stroke, and early treatment of stroke.

RESULTS

In response to the questions about the signs and symptoms of stroke, group 1 mentioned dizziness and comprehension disorder as a symptom of stroke more frequently than the other group. Stress was the second most frequently mentioned risk factor (by 81% of group 1 and 80.5% in group 2). When the participants were asked about the sources of information about stroke, family circle and friends were the most frequently mentioned sources for both groups.

CONCLUSION

The present study can serve as a guide in planning training to improve stroke awareness in the future, especially by including individuals whose first-degree relatives had a stroke.

Adequate Knowledge of Stroke Symptoms, Risk Factors, and Necessary Actions in the General Population of Southern Poland

BACKGROUND AND OBJECTIVES

Stroke is the third most common cause of mortality in developed countries and the primary cause of neurological disability in adults. Recombinant tissue plasminogen activator administered intravenously within 4.5 h from the onset of symptoms constitutes a gold standard in the treatment of acute ischemic stroke. Prompt hospital admission is the prerequisite of effective thrombolysis. Therefore, stroke awareness in the general population is the key factor in timely recognition of the acute stroke victims and determines proper actions. Therefore, the purpose of this study was to determine the awareness of stroke in the general population of the Silesian voivodeship, the most populated region of Poland. We assessed also the "adequate knowledge of stroke", a combined measure of the optimal level of stroke awareness, as a prerequisite for effective stroke management, and aimed to identify most impacting factor for adequate stoke knowledge, to help shaping education strategies.

MATERIALS AND METHODS

A proprietary anonymous questionnaire consisting of 15 items related to stroke was used in this research. A total of 1134 individuals were surveyed. Additionally to the knowledge of individual aspects of stroke, we assessed "adequate knowledge of stroke", which was combined measure of risk factors, symptoms, and actions in the case of acute stroke.

RESULTS

The accurate definition of stroke was selected by 834 participants (73.5%). The vast majority of them indicated that a stroke is an emergency (92.8%) and medical assistance is required (97.5%). However, 42.4% of respondents did not know any specific symptom of stroke and only 38.6% participants were able to list two or more risk factors, which resulted in only 36.3% of individuals with adequate knowledge of stroke. Education duration, previous occurrence of stroke in relatives or friends, gender and place of residence were identified as independent predictors of adequate knowledge of stroke.

CONCLUSIONS

1. Knowledge of stroke in the population of southern Poland is low and may be considered insufficient to address the needs of timely management in the action chain. 2. Previous occurrence of stroke in the relatives or friends is the most impacting factor for adequate knowledge of stroke.

Effect of COVID-19 pandemic on stroke admission rates in a Norwegian population

Objectives

There are concerns that public anxiety around COVID‐19 discourages patients from seeking medical help. The aim of this study was to see how lockdown due to the pandemic affected the number of admissions of acute stroke.

Methods

All patients discharged from Akershus University Hospital with a diagnosis of transient ischemic attack (TIA) or acute stroke were identified by hospital chart review. January 3 to March 12 was defined as before, and March 13 to April 30 as during lockdown.

Results

There were 21.8 admissions/week before and 15.0 admissions/week during the lockdown (P < .01). Patients had on average higher NIHSS during the lockdown than before (5.9 vs. 4.2, P = .041). In the multivariable logistic regression model for ischemic stroke (adjusted for sex, age, living alone and NIHSS ≤ 5), there was an increased OR of 2.05 (95% CI 1.10‐3.83, P = .024) for not reaching hospital within 4.5 hours during the lockdown as compared to the period before the lockdown.

Conclusion

There was a significant reduction in number of admissions for stroke and TIAs during the lockdown due to the COVID‐19 pandemic in Norway.

Knowledge on Signs and Risk Factors in Stroke Patients

Background: There is a pressing need to contribute evidence to the improvement in the early identification of signs and symptoms associated with strokes, and address the treatment-seeking delays. The objective of this study is to describe the knowledge regarding the warning signs and risk factors (RFs) among stroke patients, as well as of their attitudes toward a suspected event, and the analysis of its possible relationship with the socio-demographic and clinical characteristics of these patients. Method: A cross-sectional study was designed, in which all stroke patients admitted consecutively to the Burgos University Hospital (Spain) were included. The principal outcomes were the patient’s ability to identify two RFs and two warning signs and the patient’s hypothetical response to a possible stroke event. The possible factors associated with the knowledge of warning signs, RFs, and the correct response to a new event were studied using univariate and multivariate regression analysis. Results: A total of 529 patients were included. Having a higher education level or a history of prior stroke were associated with a greater degree of knowledge of warning signs (odds ratio (OR) 3.19, 95% confidence interval (CI) 1.70–5.74, p = 0.003; OR 3.54, 95%CI 2.09–5.99, p ≤ 0.001, respectively), RFs (OR 3.15, 95%CI 1.75–5.67, p = 0.008; OR 4.08, 95%CI 2.41–6.91, p = 0.002, respectively), and the correct response to a possible stroke (OR 1.82, 95%CI 1.16–2.86; p = 0.030; OR 2.11, 95%CI 1.29–3.46, p = 0.022, respectively). Conclusion: Knowledge of warning signs or stroke RFs is low in the hospitalized patients. A previous stroke or secondary/higher education levels are the predictor factors that increase the probability of knowledge of warning signs, RFs, or reaction to possible event.

Understanding the seriousness of a stroke is essential for appropriate help-seeking and early arrival at a stroke centre: A cross-sectional study of stroke patients and their bystanders

Introduction

Only a minority of patients with acute ischaemic stroke receive reperfusion treatment, primarily due to prehospital delay. We aimed to investigate predictors of a primary contact to the emergency medical services, arrival at stroke centre within 3 h of symptom onset and initiation of reperfusion therapy in patients with acute stroke.

Patients and methods

We conducted a cross-sectional study of consecutive patients with acute ischaemic stroke, intracerebral haemorrhage or transient ischaemic attack. Structured interviews of patients and bystanders were performed and combined with clinical information from the Danish Stroke Registry. Eligible patients were aged ≥18 years and were independent in activities of daily living before the stroke.

Results

We included 435 patients. Presence of a bystander at symptom onset and knowledge of ≥2 core symptoms of stroke were associated with a primary emergency medical services contact. Higher stroke severity and patients or bystanders perceiving the situation as very serious were associated with a primary emergency medical services contact (OR_patients 2.10; 95% CI 1.12-3.95 and OR_bystanders 22.60; 95% CI 4.98-102.67), <3 h from onset to arrival (OR_patients 3.01; 95% CI 1.46-6.21 and OR_bystanders 4.44; 95% CI 1.37-14.39) and initiation of reperfusion therapy (OR_patients 3.08; 95% CI 1.23-7.75 and OR_bystanders 4.70; 95% CI 1.14-19.5).Conclusion: Having a bystander, knowledge of ≥2 core symptoms and understanding that stroke is a serious event are associated with appropriate help-seeking behaviour, shorter prehospital delay and higher chance of reperfusion therapy in acute stroke patients.

Variation in Knowledge of Stroke Warning Signs by Age and Presence of Conventional Risk Factors: A Community Health Survey in Korea

BACKGROUND

It is important to recognize stroke in the general public.

OBJECTIVES

The purpose of this study was to investigate factors affecting knowledge of stroke warning signs (SWSs) according to age group in the Korean population.

METHODS

This study is a cross-sectional study. Using data from the Korean Community Health Survey conducted in Korea in 2017, 198 403 subjects were analyzed. Knowledge about SWSs was assessed by face-to-face interviews using structured close-ended questionnaires with 5 items about stroke symptoms (sudden unilateral weakness of face, arm or leg; sudden difficulty in speaking, or trouble understanding speech; sudden visual impairment in 1 eye, or double vision; sudden dizziness or loss of balance; and sudden severe headache).

RESULTS

The overall percentage of subjects with good knowledge of SWSs (>4 correct answers to the SWS questionnaire) was 66.5%. It was highest in the middle-aged subjects (72.6%), followed by the young subjects (63.5%) and the older subjects (61.5%). The youngest of the young subjects and the oldest of the older subjects had the least knowledge. Subjects with conventional risk factors generally had more knowledge about SWSs, except for those with diabetes mellitus. However, in the young subjects, knowledge about SWSs was not increased by the presence of conventional risk factors such as hypertension and dyslipidemia.

CONCLUSION

Stoke risk factors are increasing among young people; they still have poor knowledge about SWSs. More education is needed to increase appropriate treatment, especially in young people with stroke-related risk factors.

Temporal Trends and Risk Factors for Delayed Hospital Admission in Suspected Stroke Patients

(1) Background: The benefit of acute ischemic stroke (AIS) treatment declines with any time delay until treatment. Hence, factors influencing the time from symptom onset to admission (TTA) are of utmost importance. This study aimed to assess temporal trends and risk factors for delays in TTA. (2) Methods: We included 1244 consecutive patients from 2015 to 2018 with suspected stroke presenting within 24 h after symptom onset registered in our prospective, pre-specified hospital database. Temporal trends were assessed by comparing with a cohort of a previous study in 2006. Factors associated with TTA were assessed by univariable and multivariable regression analysis. (3) Results: In 1244 patients (median [IQR] age 73 [60–82] years; 44% women), the median TTA was 96 min (IQR 66–164). The prehospital time delay reduced by 27% in the last 12 years and the rate of patients referred by Emergency medical services (EMS) increased from 17% to 51% and the TTA for admissions by General Practitioner (GP) declined from 244 to 207 min. Factors associated with a delay in TTA were stroke severity (beta−1.9; 95% CI–3.6 to −0.2 min per point NIHSS score), referral by General Practitioner (GP, beta +140 min, 95% CI 100–179), self-admission (+92 min, 95% CI 57–128) as compared to admission by emergency medical services (EMS) and symptom onset during nighttime (+57 min, 95% CI 30–85). Conclusions: Although TTA improved markedly since 2006, our data indicates that continuous efforts are mandatory to raise public awareness on the importance of fast hospital referral in patients with suspected stroke by directly informing EMS, avoiding contact of a GP, and maintaining high effort for fast transportation also in patients with milder symptoms.

"Worth the Walk": Culturally Tailored Stroke Risk Factor Reduction Intervention in Community Senior Centers

Background Racial/ethnic minority older adults have worse stroke burden than non-Hispanic white and younger counterparts. Our academic-community partner team tested a culturally tailored 1-month (8-session) intervention to increase walking and stroke knowledge among Latino, Korean, Chinese, and black seniors. Methods and Results We conducted a randomized wait-list controlled trial of 233 adults aged 60 years and older, with a history of hypertension, recruited from senior centers. Outcomes were measured at baseline (T0), immediately after the 1-month intervention (T1), and 2 months later (T2). The primary outcome was pedometer-measured change in steps. Secondary outcomes included stroke knowledge (eg, intention to call 911 for stroke symptoms) and other self-reported and clinical measures of health. Mean age of participants was 74 years; 90% completed T2. Intervention participants had better daily walking change scores than control participants at T1 (489 versus -398 steps; mean difference in change=887; 97.5% CI, 137-1636), but not T2 after adjusting for multiple comparisons (233 versus -714; mean difference in change=947; 97.5% CI, -108 to 2002). The intervention increased the percent of stroke symptoms for which participants would call 911 (from 49% to 68%); the control group did not change (mean difference in change T0-T1=22%; 99.9% CI, 9-34%). This effect persisted at T2. The intervention did not affect measures of health (eg, blood pressure). Conclusions This community-partnered intervention did not succeed in increasing and sustaining meaningful improvements in walking levels among minority seniors, but it caused large, sustained improvements in stroke preparedness.

A review of mobile stroke units

PURPOSE OF REVIEW

Mobile stroke units (MSUs) for prehospital treatment and management of patients with acute stroke have been developed more than a decade ago and is currently spreading worldwide. This review discusses the history of MSU and current operations and research.

RECENT FINDINGS

Multiple studies have shown that MSU can significantly reduce treatment time with a tenfold increase of patients treated within the first 60 min of symptom onset. Recent preliminary results from the Berlin Prehospital or Usual Delivery of Acute Stroke Care trial (B-PROUD) showed a positive shift in modified Rankin Scale (mRS) scores at 3 months for patients treated in MSUs. Two German studies indicate that the MSU model is cost effective by reducing disability and improving adjusted quality-life years after stroke. The MSU model for prehospital management of acute stroke is spreading worldwide. More research is needed, however, to establish cost-effectiveness, efficacy and best setting for prehospital stroke management.

A Unique Approach to Quality Improvement Within the Stroke System of Care Utilizing Developmental Evaluation

Stroke is a significant cause of death that requires multiple systems of care to work together to prevent incidence and improve patient outcomes. The Wisconsin Coverdell Stroke Program partnered with a Model Hospital to understand and improve the stroke system of care in one community. Developmental evaluation (DE) is an approach in which evaluators collaborate closely with project stakeholders to examine complex processes and systems within changeable contexts to develop interventions to improve outcomes. DE was used to assess this community's stroke systems across the care continuum through process mapping with Model Hospital staff and through key stakeholder interviews with Model Hospital and emergency medical services staff, patients, and caregivers. Process mapping identified how patients and health care data flow through the system of care and highlighted areas where streamlining could improve the movement of patients and data across the care continuum. Interviews with stakeholders unveiled challenges and successes about how patient data are accessed and shared across the care continuum, and ideas for improving systems to be more efficient and supportive of stroke prevention and patient outcomes. Overall, DE was valuable in gaining an in-depth understanding of this complex environment to develop strategies to enhance stroke systems of care.

Utstein recommendation for emergency stroke care

Background

Recent advances in treatment for stroke give new possibilities for optimizing outcomes. To deliver these prehospital care needs to become more efficient.

Aim

To develop a framework to support improved delivery of prehospital care. The recommendations are aimed at clinicians involved in prehospital and emergency health systems who will often not be stroke specialists but need clear guidance as to how to develop and deliver safe and effective care for acute stroke patients.

Methods

Building on the successful implementation program from the Global Resuscitation Alliance and the Resuscitation Academy, the Utstein methodology was used to define a generic chain of survival for Emergency Stroke Care by assembling international expertise in Stroke and Emergency Medical Services (EMS). Ten programs were identified for Acute Stroke Care to improve survival and outcomes, with recommendations for implementation of best practice.

Conclusions

Efficient prehospital systems for acute stroke will be improved through public awareness, optimized prehospital triage and timely diagnostics, and quick and equitable access to acute treatments. Documentation, use of metrics and transparency will help to build a culture of excellence and accountability.

Barriers from calling ambulance after recognizing stroke differed in adults younger or older than 75 years old in China

BACKGROUND

As health behavior varies with increasing age, we aimed to examine the potential barriers in calling emergency medical services (EMS) after recognizing a stroke among 40-74- and 75-99-year-old adults.

METHODS

Data were obtained from a cross-sectional community-based study (FAST-RIGHT) that was conducted from January 2017 to May 2017 and involved adults (age ≥ 40 years) across 69 administrative areas in China. A subgroup of residents (153675) who recognized stroke symptoms was analyzed. Multivariable logistic regression models were performed in the 40-74 and 75-99 age groups, separately, to determine the factors associated with wait-and-see behaviors at the onset of a stroke.

RESULTS

In the 40-74 and 75-99 age groups, the rates of participants who chose "Self-observation at home" were 3.0% (3912) and 3.5% (738), respectively; the rates of "Wait for family, then go to hospital" were 31.7% (42071) and 33.1% (6957), respectively. Rural residence, living with one's spouse, low income (< 731 US $ per annum), having a single avenue to learn about stroke, and having friends with stroke were factors associated with waiting for one's family in both groups. However, unlike in the 40-74 age group, sex, number of children, family history, and stroke history did not influence the behaviors at stroke onset in the 75-99 age group.

CONCLUSIONS

Different barriers from recognizing stroke and calling an ambulance exist in the 40-74 and 75-99 age groups in this specific population. Different strategies that mainly focus on changing the "Wait for family" behavior and emphasize on immediately calling EMS are recommended for both age groups.

Cardiovascular surgery experience does not significantly improve patients' response to stroke

OBJECTIVES

Patients with a history of cardiovascular surgery are at risk of stroke, and immediately calling emergency medical services (EMS) after stroke onset is crucial to receiving effective reperfusion therapy. We aimed to determine the effect of a history of cardiovascular surgery on patients' ability to recognize stroke and intent to call EMS.

METHODS

We performed a cross-sectional community-based study from January 2017 to May 2017. A total population of 186,167 individuals, recruited from 69 administrative areas across China, was analyzed. Different multivariable logistic regression models were performed to identify the associations between cardiovascular surgical history and stroke recognition or intent to call EMS, respectively.

RESULTS

0.1% of the total population had a history of cardiovascular surgery. In the surgery group, the estimated stroke recognition rate (SRR) and correct action rate (CAR) were 84.9% and 74.7%, respectively. The prevalence of cardiovascular risk factors was significantly higher in the surgery group. Cardiovascular surgical history was not associated with recognition of stroke across different models. The surgery group was more likely to call EMS, but the difference was not significant after full adjustment (OR: 1.40, 95% CI: 0.99-1.98, p = .0572).

CONCLUSIONS

Cardiovascular surgical history does not influence patients' likelihood of calling EMS more often at stroke onset. Patients receiving cardiovascular surgeries should be counseled regarding stroke recognition, proper response to stroke, and the importance of controlling risk factors.

Differences in the awareness of stroke symptoms and emergency response by occupation in the Korean general population

We evaluated the difference in awareness of stroke warning signs (SWS) and emergency response among occupational groups in the community-dwelling population. From the 2016 Korea Community Health Survey, a total of 10,445 individuals without stroke were included in the analysis. Multiple logistic regression analysis was used to explore the association of occupation with awareness of SWS and correct emergency response. SWS included the following: sudden numbness or weakness, sudden difficulty speaking or understanding speech, sudden dizziness, sudden visual impairment, and sudden severe headache. Respondents’ occupation was classified into six groups: managers and professionals (MP); clerks; service and sales workers (SSW); agricultural, forestry, and fishery workers (AFFW); mechanical and manual laborers (MML); or housewives and unemployed people (HUP). Awareness of each SWS was the same with the highest for MP and lowest for AFFW. After adjusting for socio-demographic factors, compared to MP (reference), AFFW (odds ratio 0.49; 95% confidence interval 0.36–0.67), HUP (0.55; 0.40–0.75), MML (0.57; 0.42–0.79), and SSW (0.62; 0.45–0.86) had significantly lower ORs for knowing at least one of the SWS. Additionally, AFFW (0.79; 0.66–0.96) and MML (0.76; 0.63–0.91) had significantly lower ORs for knowing all five SWS compared to MP. However, there was no significant occupational difference in correct emergency response when a stroke occurred. To improve stroke literacy and to reduce the disparity of awareness of SWS in community settings, public health efforts with an emphasis on AFFW and MML are needed.

Recommendations for the Establishment of Stroke Systems of Care: A 2019 Update

In 2005, the American Stroke Association published recommendations for the establishment of stroke systems of care and in 2013 expanded on them with a statement on interactions within stroke systems of care. The aim of this policy statement is to provide a comprehensive review of the scientific evidence evaluating stroke systems of care to date and to update the American Stroke Association recommendations on the basis of improvements in stroke systems of care. Over the past decade, stroke systems of care have seen vast improvements in endovascular therapy, neurocritical care, and stroke center certification, in addition to the advent of innovations, such as telestroke and mobile stroke units, in the context of significant changes in the organization of healthcare policy in the United States. This statement provides an update to prior publications to help guide policymakers and public healthcare agencies in continually updating their stroke systems of care in light of these changes. This statement and its recommendations span primordial and primary prevention, acute stroke recognition and activation of emergency medical services, triage to appropriate facilities, designation of and treatment at stroke centers, secondary prevention at hospital discharge, and rehabilitation and recovery.

Perceptions of Stroke and Associated Health-Care-Seeking Behavior in Northern Tanzania: A Community-Based Study

BACKGROUND

Little is known about knowledge of stroke symptoms, perceptions of self-risk, and health-care-seeking behavior for stroke in East Africa.

METHODS

A 2-stage randomized population-based cluster survey with selection proportional to population size was performed in northern Tanzania. Self-identified household health-care decision makers were asked to list all symptoms of a stroke. They were further asked if they thought they had a chance of having a stroke and where they would present for care for stroke-like symptoms. A socioeconomic status score was derived via principal component analysis from 9 variables related to wealth.

RESULTS

Of 670 respondents, 184 (27.4%) knew a conventional stroke symptom and 51 (7.6%) thought they had a chance of having a stroke. Females were less likely to perceive themselves to be at risk than males (OR 0.49, 95% CI 0.28-0.89, p = 0.014). Of respondents, 558 (88.3%) stated they would present to a hospital for stroke-like symptoms. Preference for a hospital was not associated with knowledge of stroke symptoms or perception of self-risk but was associated with a higher socioeconomic status score (p < 0.001).

CONCLUSIONS

Knowledge of stroke symptoms and perception of self-risk are low in northern Tanzania, but most residents would present to a hospital for stroke-like symptoms.

Understanding delays in acute stroke care: a systematic review of reviews

Background

Stroke is the leading cause of adult long-term disability in Western countries. Intravenous thrombolytic therapy with recombinant tissue plasminogen activator is safe and effective within the first 4.5 h after the onset of stroke. Various factors delaying acute stroke care have been identified in the literature. This review aimed to provide an overview of factors delaying acute stroke care and attempted to show how they interact in a synthetic framework.

Methods

We conducted a systematic review of literature reviews published in Medline and DORIS until 2016 on factors influencing acute stroke pathway timeframe.

Results

We analyzed 31 reviews that cover all factors of delays from stroke onset to treatment. We identified 27 factors that had a significant impact on acute stroke care and can be categorized into four distinct categories: patient-related factors, training, resources and lack of coordination. We also reported associations between factors observed in both between categories (mainly between patients and organizational/logistical factors) and within categories.

Conclusion

This review provides a wide overview of factors influencing acute stroke pathway. Since it was observed that the identified factors were interrelated, they needed to be analyzed in a systematic way. We hence created a synthetic framework that combines several categories of factors while assuming that factor weight varies from a study context to another. Better knowledge on underlying mechanisms between factors would provide crucial improvement of the interventions aiming at reducing delays in both pre-hospital and inhospital stages. For future research, we recommend adopting a systemic perspective on factors influencing acute stroke pathway.

Improving Prehospital Stroke Services in Rural and Underserved Settings With Mobile Stroke Units

In acute stroke management, time is brain, as narrow therapeutic windows for both intravenous thrombolysis and mechanical thrombectomy depend on expedient and specialized treatment. In rural settings, patients are often far from specialized treatment centers. Concurrently, financial constraints, cutting of services and understaffing of specialists for many rural hospitals have resulted in many patients being underserved. Mobile Stroke Units (MSU) provide a valuable prehospital resource to rural and remote settings where patients may not have easy access to in-hospital stroke care. In addition to standard ambulance equipment, the MSU is equipped with the necessary tools for diagnosis and treatment of acute stroke or similar emergencies at the emergency site. The MSU strategy has proven to be effective at facilitating time-saving stroke triage decisions. The additional on-board imaging helps to determine whether a patient should be taken to a primary stroke center (PSC) for standard treatment or to a comprehensive stroke center (CSC) for advanced stroke treatment (such as intra-arterial therapy) instead. Diagnosis at the emergency site may prevent additional in-hospital delays in workup, handover and secondary (inter-hospital) transport. MSUs may be adapted to local needs-especially in rural and remote settings-with adjustments in staffing, ambulance configuration, and transport models. Further, with advanced imaging and further diagnostic capabilities, MSUs provide a valuable platform for telemedicine (teleradiology and telestroke) in these underserved areas. As MSU programmes continue to be implemented across the world, optimal and adaptable configurations could be explored.

The knowing-doing gap in acute stroke-Does stroke knowledge translate into action?

In this study, we suggest that there is a substantial knowing-doing gap in acute stroke, as increased stroke knowledge was not associated with earlier hospital admission.
