Public perception of stroke warning signs and knowledge of potential risk factors

Various Sociodemographic Variables on Acute and Inpatient Stroke Care

BACKGROUND

Key factors affecting stroke outcomes include swift diagnosis and early treatment, however, disparities in symptom recognition, particularly in minority groups, impact timely care. This study examines the influence of patient characteristics on stroke metrics, focusing on factors such as age, sex, ethnicity, race, insurance status, and language preference.

METHODS

We conducted a multicenter, retrospective study using the National Hospital Corporation of America (HCA) database, analyzing 37,956 acute ischemic stroke (AIS) cases from 170 HCA hospitals between 2017 and 2022. We evaluated the impact of demographic and patient-specific factors on tPA administration rates, time-to-tPA (TtPA), and hospital length of stay (LOS). Statistical methods included odds ratios, one-way ANOVA, mixed-effects models, and negative binomial regression.

RESULTS

Factors affecting tPA administration included age, sex, and insurance status. Patients aged 45 and older and those with Medicaid or Medicare were less likely to receive tPA. NIH Stroke Scale (NIHSS) scores significantly influenced tPA administration rates and TtPA. Language preference did not impact tPA administration rates or TtPa, but non-English speakers experienced longer hospital stays. Hispanic and Black patients also had longer LOS compared to non-Hispanic and White patients, respectively.

CONCLUSION

This study underscores the need for targeted interventions to address disparities in stroke management and outcomes. Future research should explore the underlying causes of these differences and develop strategies to enhance stroke care equity across diverse patient populations.

Predictors and Correlates of Prehospital Delay Among Acute Stroke Patients in Thiruvananthapuram District, Kerala: A Cross-Sectional Survey

Introduction Stroke is a significant global public health challenge, contributing to high mortality rates and long-term disability. Beyond its physiological impact, stroke imposes a substantial socioeconomic burden on patients, families, and healthcare systems. Timely intervention, particularly through the prompt administration of reperfusion therapies, is crucial in reducing adverse outcomes. However, delays in reaching a healthcare facility after symptom onset often prevent patients from receiving these lifesaving treatments. Understanding the prevalence and factors contributing to prehospital delays is essential for improving stroke care and patient outcomes. This study aimed to assess the prevalence of prehospital delays and their correlates among stroke patients in Thiruvananthapuram district, Kerala, while also exploring the situational challenges patients face in accessing healthcare facilities. Materials and methods A hospital-based cross-sectional survey was conducted among 170 patients with confirmed acute stroke who presented to the emergency departments of four hospitals in Thiruvananthapuram district. Patients arriving within four and a half hours of symptom onset were classified as "early arrivals," while those arriving after this period were categorized as "delayed/late arrivals." Data collection was facilitated using Open Data Kit software and analyzed with IBM SPSS Statistics for Windows, Version 22.0 (Released 2013; IBM Corp., Armonk, NY, USA). Univariate and multivariate analyses were performed to identify associations. Additionally, freewheeling interviews were coded to complement and validate the quantitative findings. Results The median time from symptom onset to hospital arrival was 6.75 hours (IQR: 2.27-17.48 hours), with 40% of stroke patients experiencing prehospital delays. Bivariate analysis revealed significant associations between delay and factors such as age, housing type, income source, occupation, socioeconomic status, presence of dependents, choice of healthcare facility, number of facilities approached, and Modified Rankin Scale score. Multiple regression analysis identified housing type and the number of facilities approached as significant predictors of prehospital delay. Freewheeling interviews further indicated that, regardless of sociodemographic characteristics, hesitation, reluctance, and self-assessment were the primary reasons for delayed hospital arrival. Conclusions The study identified a high prevalence of prehospital delay (40%) among acute stroke patients in Thiruvananthapuram, the capital city of Kerala. These findings emphasize the need for health promotion strategies aimed at increasing public awareness of early stroke symptoms, ensuring the direct transfer of patients to hospitals equipped with CT scan and thrombolysis facilities, and standardizing referral processes with uniform protocols to minimize delays and improve patient outcomes.

Assessment of knowledge and awareness of stroke among Arabic speaking adults: unveiling the current landscape in seven countries through the first international representative study

Introduction

While several studies have examined stroke public knowledge and awareness in individual countries within the Middle East and North Africa (MENA) region, none have provided a comprehensive cross-country assessment.

Purpose

To assess public stroke knowledge and awareness among Arabic-speaking adults in seven MENA countries and identify associated factors.

Materials and methods

An online cross-sectional survey was self-administered by the public population in Iraq, Lebanon, Sudan, Jordan, United Arab Emirates, Syria, and Saudi Arabia (April 2021-2023). Associations of stroke risk factors, early symptoms, and consequences with socio-demographics and medical history were analyzed using logistic regression models.

Results

Of 4,090 participants (58.3% females), 42.9% identified four out of five correct answers related to general stroke knowledge. Only 25.2% identified all stroke risk factors, 24.7% recognized all symptoms, and 37.5% knew all possible consequences. Results show consistent pattern of high identification for at least one risk factor and consequences across all countries (96.3 to 99.8% and 86.2 to 100%, respectively), with varying levels of early symptom identification (56.8 to 97.9%). Females were more likely to identify a stroke risk factor, symptom, and consequence compared to males (OR = 2.525, 2.474, and 2.302, respectively, p < 0.001). Employed, urban residents, and those with higher education demonstrated better stroke awareness.

Conclusion

The sample showed variable levels of stroke knowledge among the public, underscoring the pressing need for targeted community initiatives, media campaigns, and educational interventions. These efforts are paramount for improving awareness, early detection, and timely response, especially in countries with lower levels of community stroke awareness.

Regional Disparities in Prehospital Delay of Acute Ischemic Stroke: The Korean Stroke Registry

BACKGROUND

Late hospital arrival keeps patients with stroke from receiving recanalization therapy and is associated with poor outcomes. This study used a nationwide acute stroke registry to investigate the trends and regional disparities in prehospital delay and analyze the significant factors associated with late arrivals.

METHODS

Patients with acute ischemic stroke or transient ischemic attack between January 2012 and December 2021 were included. The prehospital delay was identified, and its regional disparity was evaluated using the Gini coefficient for nine administrative regions. Multivariate models were used to identify factors significantly associated with prehospital delays of >4.5 h.

RESULTS

A total of 144,014 patients from 61 hospitals were included. The median prehospital delay was 460 min (interquartile range, 116-1912), and only 36.8% of patients arrived at hospitals within 4.5 h. Long prehospital delays and high regional inequality (Gini coefficient > 0.3) persisted throughout the observation period. After adjusting for confounders, age > 65 years old (adjusted odds ratio [aOR] = 1.23; 95% confidence interval [CI], 1.19-1.27), female sex (aOR = 1.09; 95% CI, 1.05-1.13), hypertension (aOR = 1.12; 95% CI, 1.08-1.16), diabetes mellitus (aOR = 1.38; 95% CI, 1.33-1.43), smoking (aOR = 1.15, 95% CI, 1.11-1.20), premorbid disability (aOR = 1.44; 95% CI, 1.37-1.52), and mild stroke severity (aOR = 1.55; 95% CI, 1.50-1.61) were found to independently predict prehospital delays of >4.5 h.

CONCLUSION

Prehospital delays were lengthy and had not improved in Korea, and there was a high regional disparity. To overcome these inequalities, a deeper understanding of regional characteristics and further research is warranted to address the vulnerabilities identified.

Stroke awareness and knowledge in Sudan: a cross-sectional analysis of public perceptions and understanding

Introduction

Stroke, a leading cause of morbidity and mortality globally, demands heightened awareness and knowledge for effective preventive strategies and tailored response. Sudan is classified as a low income country with a low rate of literacy, lack of knowledge, and awareness about diseases. Thus, this study aimed to assess stroke awareness and knowledge among Sudanese population, and identify the associated factors influencing awareness.

Methods

A cross-sectional study conducted between October and November 2022 through a self-administered online survey distributed via various social media platforms. The study involved adults aged 18 years and above through snow-ball sampling technique. The survey covered general awareness and knowledge concerning stroke risk factors, consequences, and the appropriate responses taken during acute stroke attacks.

Results

A total of 410 participants were enrolled in the study, majority (93.4%) were from urban area and had university degree (92.4%). Furthermore, 92.2% were aware about stroke and 74.9% were able to recognize the symptoms of stroke. Only 40.2% identified all correct answers, 96.3, 92.3, and 95.1% recognized at least one risk factor, early symptom, and consequences, respectively. Females were significantly more than males able to identify at least one risk factor. Almost all participants (99.5%) perceived stroke as a serious disease (99.5%). Notably, 86.3% would promptly transport a suspected stroke patient to the hospital. The multivariable analysis showed that females versus males and patients with depression versus without depression had significantly higher odds to identify at least one risk factor (OR of 14.716 [95% CI 1.901; 113.908] and 0.241 [95% CI 0.059; 0.984], respectively).

Conclusion

The study concluded that stroke knowledge and awareness among Sudanese population is suboptimal. Furthermore, early stroke recognition and intake of the appropriate management strategies are lacking which highlights the need for targeted education and awareness campaigns.

Assessing the Awareness on Symptoms and Risk Factors of Stroke amongst Rural Community in Central Region of Malaysia: A Cross-Sectional Survey

Background

As the third leading cause of mortality in Malaysia, stroke is recognised as a medical emergency which requires urgent medical attention within a limited timeframe to prevent exacerbation of the brain damage and death in patients. Recent report revealed a high prevalence of pre-hospital delay amongst the stroke patients due to the lack of awareness on symptoms and risk factors of stroke, as well as poor understanding on appropriate action towards stroke. A number of studies had assessed stroke awareness amongst urban population residing in central region of Malaysia but yet amongst rural population.

Methods

A cross-sectional survey was conducted amongst individuals residing in rural districts of Selangor by using a set of questionnaires assessing the sociodemographic characteristics, as well as the awareness and action towards stroke symptoms and risk factors.

Results

All 343 respondents were able to recognise at least one modifiable risk factor for stroke. Meanwhile, only 36.44% were able to identify all the stroke symptoms. Despite majority of them were familiar with the stroke term, less than half of the respondents were aware of calling the emergency medical service as the appropriate action towards stroke symptoms.

Conclusion

The present study indicated a poor level of awareness and action towards stroke symptoms and risk factors amongst rural population residing in Selangor.

Knowledge of symptoms, risk factors, and treatment centers of stroke among the general population of Al-Ahsa, Saudi Arabia

Background

In Saudi Arabia, stroke is a significant cause of illness and mortality progressively becoming more serious. Studies have indicated that modifiable cardiovascular risk factors are responsible for a significant portion of the burden caused by stroke, which could be targeted through public awareness.

Objective

We evaluated the level of knowledge about stroke among the general population of the Al-Ahsa, Saudi Arabia. Furthermore, association between stroke level of knowledge and sample characteristics was analyzed.

Methods

This was a cross-sectional study conducted from February 22, 2023, to March 22, 2023, using a convenience sampling technique. An electronic Google Forms survey was distributed through social media, to reach the maximum number of participants.

Results

This study included a total of 500 participants from Al-Ahsa, Saudi Arabia. Forty-three percentage of participants were male, while 57% were females. Most participants were of a younger age, where 66.6% were 18-39 years. The most recognized stroke symptom, risk factor, and stroke treatment center were dizziness/vertigo (91%), hypertension (97%), and King Fahad Hospital, respectively. Those with higher education possessed a greater level of stroke-related knowledge than other demographic groupings.

Conclusion

The general public of Al-Ahsa demonstrated a high level of knowledge about stroke symptoms (82.6%), risk factors (90%), and treatment facilities (80%). However, it was evident that the general public failed to recognize the proper course of action in the event of a stroke.

Knowledge and Awareness of Stroke among the Elderly Population: Analysis of Data from a Sample of Older Adults in a Developing Country

Background and Objectives: Stroke prevention has traditionally concentrated on research to improve knowledge and awareness of the disease in the general population. Since stroke incidents increase with age, there is a need to focus on the elderly, a high-risk group for developing the disease. This study aimed to examine the level of stroke awareness and knowledge, their predictors, and their source of information. Materials and Methods: A prospective cross-sectional study targeted Lebanese senior citizens aged 65 years and above. A total of 513 participants enrolled in the study through a self-administered survey distributed using a snowball sampling technique. Results: Most participants had appropriate baseline knowledge (more than 75% correct answers) of stroke, including risk factors, alarming signs, and preventive measures. Better knowledge of disease risks was significantly associated with having a university degree (ORa = 1.609; p = 0.029). Participants who had previous ischemic attacks showed significantly lower knowledge of the alarming signs (ORa = 0.467; p = 0.036) and prevention measures (ORa = 0.427; p = 0.029). Those suffering from depression had better knowledge of stroke alarming signs (ORa = 2.060.; p = 0.050). Seeking information from pharmacists, physicians, or the internet was not significantly associated with better knowledge of stroke risks, alarming signs, and preventive measures. Conclusions: The present study showed that seniors had fair knowledge of stroke, despite gaps in stroke prevention measures. Healthcare providers could play a leading role in improving public health by educating seniors to enhance awareness about prevention measures, detecting alarming signs, and acting fast to save a life.

Temporal Trends in Public Stroke Knowledge, 1995-2021

BACKGROUND

Outreach campaigns have sought to reduce the burden of stroke by improving knowledge of stroke risk factors (RF) and warning signs (WS). We describe trends in stroke knowledge from 1995 to 2021.

METHODS

From 1995 to 2021, 6 separate surveys were conducted in the Greater Cincinnati Northern Kentucky Region. Temporal trends in RF/WS knowledge were analyzed using logistic regression adjusting for Race, sex, age, and education.

RESULTS

In 1995, 28.6% of participants (537/1880) could name ≥2 WS, compared with 50.6% (983/1944) in 2021 (trend P<0.0001 after adjustment). In 1995, 44.5% of participants (836/1880) knew ≥2 RF, compared with 56.7% (1103/1944) in 2021 (trend P<0.0001 after adjustment). Although still improved compared with 1995, fewer participants could identify ≥2 RF in 2021 (1103/1944, 56.7%) when compared with 2011 (1287/2036, 63.2%, pairwise P<0.05). This decline in RF knowledge was disproportionately larger in women (odds ratio of 0.67 for knowledge in 2021 compared with 2011 in females, P=0.047 for the interaction between sex and study year).

CONCLUSIONS

Although stroke knowledge has overall improved since 1995, there is evidence for lost gains since 2011, particularly in women. Stroke outreach campaigns need ongoing evaluation.

Knowledge and awareness of stroke in the United Arab Emirates: a cross-sectional study of the general population

BACKGROUND

The study aimed to assess stroke knowledge among the general population in the United Arab Emirates (UAE) and determine the factors associated with stroke awareness among people.

METHODS

A cross-sectional study was conducted in the UAE between September and November 2021. The general population has self-administered an online bilingual survey (Arabic and English) distributed via social media platforms. The questionnaire covered general knowledge about stroke risk factors, consequences of stroke, and responding to somebody with acute stroke attack.

RESULTS

A total of 545 surveys were completed, with more than half of the participants being female (58.5%), married (55.4%) and employed (59.4%). The majority were less than 50 years old (90.5%) and had a university degree (71.0%). Many of the participants (70.8%) had a good general knowledge of stroke; however, around 20% of the participants were able to recognize all symptoms and risk factors of stroke. The most common sources of stroke-related information were the internet/social media (53.6%). Females were better able to correctly identify at least one stroke symptom and outcome than males (p=0.008). University education has significantly affected participants' ability to identify early stroke symptoms (p=0.001) correctly. In addition, diabetic people were more likely to recognize at least one stroke outcome than non-diabetic people (p=0.039).

CONCLUSIONS

The knowledge of stroke was good among highly educated people and females. However, the awareness of all stroke risk factors, symptoms, consequences and risk factors was inadequate among the general population of the UAE. Thus, there is still a gap between recognition of the relevant stroke and taking action among people.

Stroke related knowledge, prevention practices and associated factors among stroke patients in Taizhou, China

Stroke is characterized by high morbidity, high mortality and high disability rate, which is a major health problem worldwide. However, most community-based studies report a lack of public knowledge related to stroke. The aim of this study is to investigate stroke-related knowledge and prevention practices among stroke patients in Taizhou, China. A face-to-face survey was conducted and questionnaires were completed by 156 S patients from June 27 to August 30, 2022. A generalized linear model was applied to explore the factors influencing prevention practices. Among the total participants, 36.5% and 40.4% of them had good knowledge of the stroke-related warning signs and risk factors, respectively. Participants who had good stroke prevention practices accounted for 57.7%. The higher score of stroke-related knowledge among inpatients, the better their prevention practices (B = 0.16, 95 %CI: 0.05 ∼ 0.28). In addition, those with age ≥ 60 (B = 1.20, 95 %CI: 0.42 ∼ 1.97), females (B = 0.93, 95 %CI: 0.24 ∼ 1.61), having physical activities (B = 1.01, 95 %CI: 0.33 ∼ 1.68), or without underlying diseases (B = -1.67, 95 %CI:-2.42 ∼ -0.92) were also related with prevention practices. In general, this survey indicated that the stroke-related knowledge and prevention practices of participants were not good enough. Stroke related knowledge, age, sex, physical activity, and underlying disease were significant factors related to stroke prevention practices. These findings suggest the need to focus on stroke health education for stroke patients.

Knowledge and awareness of stroke and associated factors in the Saudi general population: a cross-sectional study

Introduction

Stroke is a major cause of death and disability globally and in Saudi Arabia as well. Prevention and management of stroke depend highly on raising knowledge and awareness about the disease.

Purpose

The purpose of this study was to evaluate Saudi adult's knowledge and awareness about stroke and determine the associated factors.

Materials and methods

A cross-sectional online survey was conducted in May-July 2022 among Saudi citizens. Assessments of stroke knowledge about risk factors, symptoms, and response to stroke symptoms were evaluated. Logistic regression was conducted to assess the association between the socio-demographic characteristics and knowledge.

Results

A total of 389 participants were enrolled with the majority (81.7%) being male participants. Less than half of the study subjects (43.3%) identified four out of five correct answers related to general knowledge about stroke. Almost all the participants were able to identify at least one risk factor associated with stroke. The majority of the participants (81.2%) believed that physical inactivity was the most common risk factor associated with stroke. Approximately three-quarters of participants considered difficulty speaking and understanding speech, followed by the sudden loss of consciousness as the most common stroke manifestation. Participants with a history of hypertension, dyslipidemia, and obesity had significantly higher odds of identifying at least one early stroke symptom (OR 2.271 [95% CI 1.402 3.677], 2.059 [95% CI 1.273 3.328], and 2.665 [95% CI 1.431 4.963], respectively).

Conclusion

Our study revealed that participants have good knowledge about stroke. Nonetheless, further efforts are required to raise awareness and educate the public to optimize and ensure better treatment outcomes.

Low levels of awareness of obstructive sleep apnoea amongst the Australian general public

Introduction: Despite the serious health implications associated with obstructive sleep apnoea, the condition remains under-diagnosed. This study aims to evaluate the awareness of the condition amongst the Australian community.

Methods: A total of 2016 respondents recruited from a web-based panel completed an online questionnaire which assessed awareness and experience of obstructive sleep apnoea and sleep-disordered breathing. The association between the level of awareness and various socio-demographic variables was analysed using uni- and multivariate analyses.

Results: The results of the questionnaire indicated that 50% and 70% of participants were unaware of adult and paediatric obstructive sleep apnoea. Socio-demographic variables including age, annual household income and education level significantly influenced a participant’s level of awareness. Approximately 8.3% of the participants had previously been diagnosed with obstructive sleep apnoea. However, 65% of participants exhibiting symptoms of daytime sleepiness had not sought health care. Paediatric sleep apnoea had been previously diagnosed in 7.1% of children residing in participant’s households but 49% of children with regular snoring had not been medically evaluated.

Conclusion: A deficiency exists in the awareness of sleep apnoea amongst the Australian general public. This is reflected in the discrepancy between the number of participants exhibiting potential symptoms and those who sought medical advice.

Knowledge and cardiovascular disease risk perception from the perspectives of prisoners and staff in a Scottish prison: a qualitative study

PURPOSE

Prisoners have an increased risk of cardiovascular disease (CVD) compared to the general population. Knowledge and risk perception of CVD can influence engagement in preventative behaviours that lower an individual's CVD risk. This paper aims to explore prisoners' knowledge of CVD, and prisoners and staff's perceptions of prisoners' CVD risk.

DESIGN/METHODOLOGY/APPROACH

This was a qualitative study in which semi-structured interviews were conducted with 16 prisoners and 11 prison and National Health Services staff in a Scottish prison. Data were analysed thematically using the framework method.

FINDINGS

Most prisoners had limited knowledge of CVD as they could not describe it or could only identify one or two risk factors or cardiovascular events. Both prisoners and staff viewed prisoners' CVD risk as either pertaining to one individual, or pertaining to the general prisoner population. Unhealthy behaviours that were believed to increase CVD risk were linked to three perceived consequences of imprisonment: mental health problems, boredom and powerlessness.

ORIGINALITY/VALUE

To the best of the authors' knowledge, this is the first study to explore the CVD knowledge of prisoners, and perceptions of CVD risk from the perspectives of prisoners and prison staff. Findings from this study indicate that CVD education needs to be a priority for prisoners, addressing knowledge of CVD, its risk and risk perceptions. Additionally, the findings indicate that individual and socio-environmental factors linked to prisoners' CVD risk need to be targeted to reduce this risk. Future research should focus on socio-environmental interventions that can lead to reducing the CVD risk of prisoners.

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.

Supplementary Information

The online version contains supplementary material available at 10.1186/s12883-022-02859-z.

• This is the first study comparing awareness of calling EMS among outpatients and public in sub-Saharan Africa

• Awareness of calling EMS or seeking immediate medical services by acute stroke was adequate among both outpatients and public

• 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

• Results call for educational campaigns on awareness of calling EMS/ seeking immediate medical assistance by stroke.

Factors associated with knowledge and awareness of stroke among the Lebanese population: A cross-sectional study

Background: Evaluation of the knowledge about stroke in the general population is extremely vital as it prevents stroke development, limits complications, and achieves better quality of life.  We assume that the general Lebanese population lacks awareness about stroke and its associated complications. This study aims to evaluate stroke knowledge and determine the factors associated with stroke awareness among the general Lebanese population.

Methods: This cross-sectional study assessed respondents’ sociodemographic characteristics and the identification of risk factors, warning signs, stroke consequences, and early response to stroke symptoms. A total of 551 Lebanese adults without a history of stroke filled in an online self-reported questionnaire publicly shared on social applications. Logistic regression analysis was performed to identify the factors associated with poor knowledge of stroke. 

Results: Among the 551 participants enrolled, 403 (74.2%) were females and 312 (56.7%) were under 30 years of age. Females compared to males and employed compared to unemployed had significantly higher odds of identifying at least one risk factor (OR=4.3 [95%CI=1.1;16.8] and 6 [95%CI=1.2;29.6], respectively). Also, when compared to unemployed, employed participants had significantly higher odds of recognizing at least one of the early stroke symptoms (OR=3.3 [95%CI=1.2;8.9]) and identifying at least one of the stroke consequences (OR=5.3 [95%CI=1.1;25.9]). Reaching a university level of education compared to a school level was associated with significantly higher odds (OR=2.3 [95%CI=1.1;4.8]) of taking a patient to a hospital.

Conclusion: Well-educated, employed, and female participants were more knowledgeable about stroke. Tailored interventions focusing on individuals with inadequate stroke literacy are needed. Further studies, more representative of the general Lebanese population with a larger sample size, are necessary to confirm our findings.

Latent class cluster analysis of knowledge on acute myocardial infarction in community residents: a cross-sectional study in Tianjin, China

OBJECTIVE

Public knowledge of early onset symptoms and risk factors (RF) of acute myocardial infarction (AMI) is very important for prevention, recurrence and guide medical seeking behaviours. This study aimed to identify clusters of knowledge on symptoms and RFs of AMI, compare characteristics and the awareness of the need for prompt treatment.

DESIGN

Multistage stratified sampling was used in this cross-sectional study. Latent GOLD Statistical Package was used to identify and classify the respondent subtypes of the knowledge on AMI symptoms or modifiable RFs. Multivariable logistic regression was performed to identify factors that predicted high knowledge membership.

PARTICIPANTS

A structured questionnaire was used to interview 4200 community residents aged over 35 in China. 4122 valid questionnaires were recovered.

RESULTS

For AMI symptoms and RFs, the knowledge levels were classified into two or three distinct clusters, respectively. 62.7% (Symptom High Knowledge Cluster) and 39.5% (RF High Knowledge Cluster) of the respondents were able to identify most of the symptoms and modifiable RFs. Respondents who were highly educated, had higher monthly household income, were insured, had regular physical examinations, had a disease history of AMI RFs, had AMI history in immediate family member or acquaintance or had received public education on AMI were observed to have higher probability of knowledge on symptoms and RFs. There was significant difference in awareness of the prompt treatment in case of AMI occurs among different clusters. 'Calling an ambulance' was the most popular option in response of seeing others presenting symptoms of AMI.

CONCLUSIONS

A moderate or relatively low knowledge on AMI symptoms and modifiable RFs was observed in our study. Identification of Knowledge Clusters could be a way to detect specific targeted groups with low knowledge of AMI, which may facilitate health education, further reduce the prehospital delay in China and improve patient outcomes.

Knowledge and Response to Stroke Among Lebanese Adults: A Population-Based Survey

Objectives

To date, research on public awareness of stroke warning symptoms, risk factors and practice in the general adult population in Lebanon is scarce. The aim of our study is to identify the level of stroke awareness in order to develop and implement preventive measures particularly in relationship to primary stroke prevention.

Methods

It is a cross-sectional study conducted among 410 adult participants from the five main governorates of Lebanon. Stroke knowledge and practice were assessed using two validated questionnaires namely the Stroke Knowledge Test (SKT) and the Stroke Action Test (STAT). Multivariable linear regression models were conducted to examine socio-demographic, social habits, and clinical factors independently associated with the SKT and the STAT scores.

Results

The mean SKT score of the participants was 9.16. 48.5% showed a poor stroke-related knowledge level and 51.5% a good knowledge level. Living in Mount Lebanon and occasional smokers showed statistically significant lower mean SKT scores; whereas, university degree and suffering from diabetes mellitus were associated with higher mean SKT scores. The mean overall STAT score was 41.3%. For 36.8% of the stroke symptoms, respondents selected call 112. The mean STAT scores of participants who get their information from the internet was statistically significantly lower. However, no association was found between the SKT score and the STAT score.

Conclusion

Knowledge of stroke risk factors was low, as was awareness of the need to call 112 in response to stroke symptoms. Hence, it is essential to develop health education programs in order to decrease stroke morbidity and mortality.

Factors associated with knowledge and awareness of stroke among the Lebanese population: A cross-sectional study

Background: Evaluation of the knowledge about stroke in the general population is extremely vital as it prevents stroke development, limits complications, and achieves better quality of life.  We assume that the general Lebanese population lacks awareness about stroke and its associated complications. This study aims to evaluate stroke knowledge and determine the factors associated with stroke awareness among the general Lebanese population.

A total of 551 Lebanese adults without a history of stroke filled in an online self-reported questionnaire publicly shared on social applications. Logistic regression analysis was performed to identify the factors associated with poor knowledge of stroke.  Results: Among the 551 participants enrolled, 403 (74.2%) were females and 312 (56.7%) were under 30 years of age. Females compared to males and employed compared to unemployed had significantly higher odds of identifying at least one risk factor (OR=4.3 [95%CI=1.1;16.8] and 6 [95%CI=1.2;29.6], respectively). Also, when compared to unemployed, employed participants had significantly higher odds of recognizing at least one of the early stroke symptoms (OR=3.3 [95%CI=1.2;8.9]) and identifying at least one of the stroke consequences (OR=5.3 [95%CI=1.1;25.9]). Reaching a university level of education compared to a school level was associated with significantly higher odds (OR=2.3 [95%CI=1.1;4.8]) of taking a patient to a hospital. Conclusion: Well-educated, employed, and female participants were more knowledgeable about stroke. Tailored interventions focusing on individuals with inadequate stroke literacy are needed. Further studies, more representative of the general Lebanese population with a larger sample size, are necessary to confirm our findings.

Awareness of cardiovascular disease among Korean women: Results from a nationwide survey

Women underestimate the risk of cardiovascular disease (CVD). It is essential to assess and raise awareness regarding CVD among women to reduce disease burden and mortality. Therefore, we investigated the awareness regarding CVD among Korean women. We conducted a nationwide survey between December 2020 and January 2021 among a representative sample of Korean women using random-digit-dialing telephonic interviews. We sought information regarding the awareness of CVD risk; recognition of symptoms and signs; and knowledge of the cause and prevention of and appropriate response to CVD. A total of 1,050 women (mean age, 60.2 ± 11.9 years) participated in the study. Approximately 52.0% of participants were unaware of CVD, and only 26% of participants had heard of CVD. Participants considered that compared to other diseases, CVD was not an important health issue for women, and few of them thought that cerebrovascular diseases and CVD were the leading causes of death (10.9% and 7.6%, respectively). After adjustment for possible confounding factors, age >70 years, rural residence, and educational attainment below college were independently associated with a lack of awareness regarding CVD. The awareness regarding CVD being the leading cause of death in women is low, and most women do not consider it an important health issue. Therefore, special attention must be paid to educate the public regarding CVD in women.

Lessons Learned From the Historical Trends on Thrombolysis Use for Acute Ischemic Stroke Among Medicare Beneficiaries in the United States

Background

The most recent time trends on intravenous thrombolysis (IVT) utilization for acute ischemic stroke was reported in 2011 using the Get with the Guidelines. Our objectives are to assess and validate the change in IVT utilization through 2014 in a national sample of Medicare beneficiaries and to examine the effect of patient, stroke center designation, and geography on IVT utilization.

Methods

We built a comprehensive national stroke registry by combining patient-level, stroke center status, and geographical characteristics, using multiple data sources. Using multiple national administrative databases from 2007 to 2014, we generated a mixed-effect logistic regression model to characterize the independent associations of patient, hospital, and geographical characteristics with IVT in 2014.

Results

Use of IVT increased consistently from 2.8% in 2007 to 7.7% in 2014, P < 0.001. Between group differences persisted, with lower odds of use in patients who were ≥86 years (aOR 0.74, 95% CI 0.65-0.83), Black (aOR 0.73, 95% CI 0.61-0.87), or treated at a rural hospital (aOR 0.88, 95% CI 0.77-1.00). Higher odds of use were observed in patients who arrived by ambulance (aOR 2.67, 95% CI 2.38-3.00), were treated at a hospital certified as a stroke center (aOR 1.96, 95% CI 1.68-2.29), or were treated at hospitals located in the most socioeconomically advantaged areas (aOR 1.27, 95% CI 1.05-1.54).

Conclusions

Between 2007 and 2014, the frequency of IVT for patients with acute ischemic stroke increased substantially, though differences persisted in the form of less frequent treatment associated with certain characteristics. These findings can inform ongoing efforts to optimize the delivery of IVT to all AIS patients nationwide.

AlSalamat H, Jirjees F, Al-Obaidi H, k. Hussain Z, El Hadidi S, Mansour S, Malaeb D, Hosseini H. Factors Associated with Knowledge and Awareness of Stroke Among the Jordanian Population: A Cross-Sectional Study

Background and objective: Stroke is the second leading cause of death in Jordan and over the world. Knowledge and awareness towards stroke play a crucial role in the management and prevention of its complications. This study aims to assess the knowledge and awareness about stroke among the Jordanian population and determine factors associated with stroke awareness. Methods: This cross-sectional study through a web-based anonymous questionnaire that needed 10 minutes to be completed. It examined sociodemographic characteristics and recognition of the risk factors, warning signs, stroke consequences, and early response to stroke symptoms. Logistic regression analysis identified the factors associated with poor knowledge of stroke.  Results: A total of 573 Jordanian adults participated in this study. The participant's ability to identify at least one early symptom of stroke and the proper response to the symptoms were significantly correlated with the educational level (OR of 3.4 and 2.5, respectively). At least one consequence of stroke was significantly associated with different demographic factors such as gender, socioeconomic income, females versus males and those with medium income versus low income had significantly higher odds (OR of 6.6 and 4.1, respectively). Conclusion: This study revealed a good knowledge and awareness level about stroke among Jordanians correlated mainly with their educational level. Therefore, new strategies should be considered to decrease the prevalence of stroke in Jordan, including the need for engagement in enhanced awareness campaigns.

Awareness, Recognition, and Response to Stroke among the General Public-An Observational Study

Objective  To evaluate awareness and response to stroke among the general public.

Materials and Methods  In this prospective, observational study, self-reported stroke awareness questionnaire was administered in 2000 consecutive participants who visited outpatient clinic of a tertiary care hospital. For data analysis, comparison included for awareness of stroke and response in case of stroke.

Results  The average age of the study participants was 39.64 ± 15.55 (17–85), with 651(32.6%) women. Among the respondents, 786(39.3%) participants mentioned stroke as blood clot in the brain; 268(13.4%) stated it as brain hemorrhage. Awareness of stroke was higher in people in cities (71.0 vs. 8.5%; p  < 0.001) and graduates (75.3 vs. 60.9%; p  < 0.001) or knew a family member or friend who had stroke (42.7 vs. 30.4%; p  < 0.001). Most commonly recognized risk factors included stress (1,152; 57.6%) and hypertension (1,148; 57.4%). Most identified warning sign was weakness of one side of body (807; 40.4%) and speech impairment (658; 32.9%). Participants who were aware of stroke knew a greater number of risk factors (3.75 ± 2.88 vs. 2.45 ± 2.66; p  < 0.001) and warning signs (2.85 ± 2.25 vs. 1.49 ± 1.41; p <0.001). Among 1,138 participants who were aware of stroke, 166 (14.6%) participants knew one correct response in case of a stroke, either call a doctor (49.3 vs. 35.0%; p <0.001) or call an ambulance (41.1 vs. 34.9%; p  = 0.055). Participants who knew one correct response to stroke had at least a family member/friend who had stroke (44.1 vs. 34.3%; p  < 0.022).

Conclusion  We report that among 56.9% of the participants who were aware of stroke most could not name more than four risk factors or three warning signs of stroke. Only 14.6% of those aware of stroke knew appropriate response to stroke.

Self-perceived acute psychological stress and risk of mortality, recurrence and disability after stroke: Mashhad Stroke Incidence Study

This longitudinal study was designed to evaluate the association between acute pre-stroke stress and the severity stroke and its outcomes including mortality, recurrence, disability and functional dependency. Patients with first-ever stroke (FES) were recruited from the Mashhad Stroke Incidence Study. Patients were asked about any acute severe pre-stroke stress in the 2 weeks prior to index stroke. Disability and functional disability were defined using modified the Rankin Scale and Barthel Index, respectively. We used logistic and ordinal regression tests to assess the association between acute pre-stroke stress and study outcomes. Among 624 patients with FES, 169 reported acute pre-stroke stress. Patients with acute pre-stroke stress were younger than those without stress (60.7 ± 14.4 vs. 66.2 ± 14.7; p < 0.001). The frequency of traditional vascular risk factors was not different in patients with and without acute pre-stroke stress. We did not find any association between acute pre-stroke stress and stroke outcomes. Although acute stress was common in our cohort, our results did not support an association between acute pre-stroke stress and the severity of stroke at admission and long-term stroke outcomes.

Establishing Stroke Services in the Republic of Georgia

INTRODUCTION

This article summarizes the medical experience in establishing stroke units and systemic thrombolysis in Georgia, which, like many other post-Soviet countries, still faces problems in organizing stroke care even after 30 years of independence.

PATIENTS AND METHODS

We created an example of treating acute stroke with systemic thrombolysis and introduced stroke units in several hospitals in the country, including standardization of the diagnostic and treatment process, consistent evaluation, and monthly feedback to the stroke unit staff.

RESULTS

Systemic thrombolysis has become a clinical routine in some large hospitals and is meanwhile reimbursed by the state insurance. The data of consecutive 1,707 stroke patients in 4 major cities demonstrated significant time lost at the prehospital level, due to failure in identifying stroke symptoms, delay in notification, or transportation. The consequent quality reports resulted in a dramatic increase in adherence to the European and national guidelines. A mandatory dysphagia screening and subsequent treatment led to a decrease in pneumonia rates.

DISCUSSION

We discuss our experience and suggestions on how to overcome clinical, financial, and ethical problems in establishing a stroke services in a developing country.

CONCLUSION

The Georgian example might be useful for doctors in other post-Soviet countries or other parts of the world.

Comparison of knowledge on stroke for stroke patients and the general population in Burkina Faso: a cross-sectional study

Background

In many parts of Africa, there is limited information on awareness of symptoms of stroke, risk factors for stroke and willingness for stroke prevention, both in the general population and in people with stroke. Knowledge and preventive efforts for stroke in patients with a history of the illness are rarely investigated. This study aims to investigate awareness of stroke symptoms in stroke patients who were admitted to hospitals within 72 hours of a confirmed stroke event in Burkina Faso. This study also aims to investigate preventive behavior for stroke for the general population.

Methods

Face-to-face interviews were conducted with the participants. The sample included 110 first-time stroke patients who had been admitted to one of three tertiary teaching hospitals in Burkina Faso within 72 hours and 750 participants from the general population, who were recruited through clustered sampling. Knowledge of stroke warning signs and current and future efforts on stroke prevention were also assessed.

Results

Only 30.9% of the stroke patients believed that they were at risk before the stroke episode. Obvious warning signs were unfamiliar to both groups. Only 1.3% of the respondents from the general population group knew sudden weakness face arm or leg as a sign of stroke. For all future efforts in stroke prevention, stroke patients demonstrated significantly lower willingness to undertake behavioral changes than the general population. Sixty-six percent and 85% of the stroke patients and the general population, respectively, were willing to take steps to reduce blood pressure.

Conclusion

Public education on stroke warning signs and strategies to increase willingness to engage in preventive behaviors are urgent in African countries. Strategies to improve public awareness for developing countries such as Burkina Faso should be designed differently from that of developed countries to incorporate local beliefs.

Effectiveness of a Cultural Stroke Prevention Program in the United States-South Asian Health Awareness About Stroke (SAHAS)

There are few stroke education programs focused on the South Asian population in the United States. The South Asian Health Awareness about Stroke (SAHAS) program was developed to provide culturally appropriate stroke education to South Asians from 2014 to 2017. Participants recruited for the SAHAS program were educated through a uniquely developed, culturally-specific, educational presentation. Each participant was asked to complete identical educational questionnaires both before (pre-) and after (post-) the intervention, which were then scored and evaluated. Overall, the 357 participants who completed the SAHAS program had a significant, modest 9% improvement in questionnaire score (p < 0.0001). After adjusting for confounders, those ≤ 60 years had a 2.9-point greater increase in score than those > 60 (p < 0.0001). Having programs targeted and developed for specific minority groups with an emphasis on familial commitment and active participation may aid in raising awareness and reducing the elevated adverse stroke outcomes in South Asians.

Migrainous Infarction and Cortical Spreading Depression

Migraine is a very common disorder of the nervous system. It shares similar physiological processes with stroke. Migrainous infarction is a rare complication of migraine with aura. The neuro-logical symptoms of migraine aura correspond to the cortical spreading depression and this depression can lead to a migrainous infarction. It is pertinent to state that the investigation and detection of the cortical depression might have a great clinical significance. Blood vessels in the cranium play an important role in the pathophysiology of migraine.  In the case of injured states of brain, the cortical spreading depression causes extreme vasoconstriction rather than vasodilation. The endothelial damage caused by the cortical spreading depression can result in hypercoagulability, leading to an increased risk of stroke. There are many genetic disorders in which migraine and stroke are the major symptoms and an insight into these disorders can help us in the understanding of complex mechanisms of migrainous infarction. It is pertinent to state that some derangements in the vascular function accompany migraine which may also serve as targets for research and treatment. This article will describe the hemodynamic and genetic relationship between migraine induced stroke and how it relates to the cortical spreading depression.

Stroke Awareness in Patients with Incident Stroke Compared to Patients without Stroke or Ischemic Heart Disease

BACKGROUND

Stroke awareness is known to influence treatment seeking and risk reduction behavior, but there is limited data from Sri Lanka and South Asia.

AIM

To describe stroke awareness in incident stroke patients and to compare with patients without stroke and/or ischemic heart disease (IHD) in a Sri Lankan tertiary-care center.

METHODS

We studied awareness of stroke in all incident stroke patients admitted to a tertiary-care center in Sri Lanka and compared with a group of age- and sex-matched patients without stroke and/or IHD, over 2 years. Knowledge on stroke mechanisms, risk factors, symptoms, prognosis, treatment, and prevention were evaluated using a 40-item interviewer-administered questionnaire and converted to a composite score of 100%. Total awareness was categorized as Very poor (<24%), Poor (25%-49%), Good (50%-74%), and Very good (>74%).

RESULTS

One hundred and sixty four incident stroke patients (mean age 62.0 ± 11.5 years; 64.6% males) and 164 patients without stroke and/or IHD were studied. Mean stroke awareness was 47.79% ± 14.6 in stroke patients, and 47.73% ± 14.9 in the nonstroke and/or IHD patients (P = .95). Of the associations studied, better stroke awareness (>50%) was associated only with higher education levels (OR 1.90, 95%CI 1.33-2.72, P < .001) in stroke patients.

CONCLUSIONS

Stroke awareness is not satisfactory in incident stroke patients and is no better than in patients without stroke and/or IHD. Better stroke awareness was associated with higher education levels.

Knowledge of Stroke Warning Signs, Risk Factors, and Response to Stroke among Lebanese Older Adults in Beirut

BACKGROUND AND OBJECTIVES

Stroke is a global burden. In Lebanon, recent studies have shown that stroke prevalence may be higher than other developing countries. While older people are particularly vulnerable to stroke, research suggests that they have poor stroke awareness. Since awareness is crucial for early hospital admission, thereby outcome, the main objectives of this study were to assess knowledge of stroke ie, symptoms, risk factors, and intended behavior in case of stroke suspicion.

METHODS

A community-based survey targeting adults aged 50 and above was conducted at 20 random pharmacies in Beirut from May to October 2018 through face to face interviews utilizing a structured questionnaire composed of open and closed ended questions. Descriptive and multivariable analyses were performed.

MAIN RESULTS

In total, 390 participants completed the questionnaire. Sixty-eight percent were able to spontaneously recall at least 1 stroke symptom, most frequently headache (29.2%), hemiparesis (25.4%), and dizziness (19.5%). Furthermore, 85.4% spontaneously recalled at least 1 risk factor, most frequently hypertension (48.2%), smoking (20.5%), and stress (43.1%). In case of stroke suspicion 57.69% would call an ambulance. Knowing a stroke patient and educational level were predictors for recall of more symptoms and risk factors for stroke. Adequate response to stroke was positively associated with identification of more stroke symptoms but inversely associated with having diabetes.

CONCLUSIONS AND RECOMMENDATIONS

There are major gaps in stroke knowledge among Beirut's older population. Culturally tailored awareness campaigns should be implemented at multiple levels using different media methods to target vulnerable populations at higher risk for stroke and their families. These campaigns should focus on improving stroke symptoms awareness and actions to take when suspecting stroke.

Effect of an educational intervention on knowledge and perception of individuals at risk for stroke in Tabuk, Saudi Arabia

Objectives:

To assess the effect of an educational program on the knowledge and perception of stroke in individuals at risk.

Methods:

This quasi experiment study, conducted in Health Education Clinics at King Salman Armed Forces Hospital, was designed to assess the knowledge of people who were at risk for stroke, before and after delivering educational content. This content comprised 4-minute face-to-face explanation by a trained educator, 99-second video clip and a short hand-out. The assessment was performed by administering a structured questionnaire.

Results:

A total of 313 people participated in this study. Before the intervention, 63.6% understood stroke to be due to a disturbance in blood flow resulting in loss of brain function. After delivery of the educational content, the percentage raised to 97.1%. Thirty-Four and Eight percent (109) of participants stated they knew stroke symptoms, and 55.96% knew 2 to 4 symptoms prior to intervention. Our educational content raised these percentages to 98.4% and 79.8% respectively. Good knowledge of stroke symptoms and risk factors was associated with younger age and higher level of education.

Conclusion:

Educational content by means of one-to-one interaction with trained educators, video clips and handouts results in significant improvement in understanding of stroke symptoms and risk factors among at-risk participants.

Awareness of stroke among patients attending primary healthcare services in Abha, Southwestern Saudi Arabia

Objectives:

To examine the awareness about major symptoms, risk factors, and response to stroke among the population in Abha, Southwestern Kingdom of Saudi Arabia. Improving stroke-related knowledge may advance stroke prevention and reduce pretreatment delay and disabilities.

Methods:

We conducted a cross-sectional study among a representative sample of primary healthcare adult patients between January-May 2016 and used a validated Arabic questionnaire to evaluate the participants’ awareness about stroke.

Results:

The study involved 1472 adults. Only 63.6% and 43.7% of participants correctly recognized thrombosis and hemorrhage as types of stroke. Commonly identified risk factors were hypertension (55.8%), dyslipidemia (45.8%), and smoking (41.9%). Sudden severe headache (54.1%), dizziness (51.0%), and difficulty in speaking (44.3%) were the most frequently recognized symptoms. The most frequently reported correct responses to stroke were contacting a doctor (73.0%), going to the hospital (67.2%), and calling an ambulance (52.4%). Improper responses to stroke (ignoring the condition or self-prescription) were noted in 18.8% of participants. Logistic regression revealed that physicians, nurses, friends and relatives as a source of knowledge were significantly associated with a lower insufficient knowledge of stroke symptoms and risk factors. On the other hand, women, persons above 40 years old, and married persons were significantly more prone to have insufficient knowledge about a proper response to stroke.

Conclusion:

Our study revealed a notable deficit of knowledge about warning symptoms, risk factors, and proper response to stroke. Health education strategies to improve stroke awareness are required and could potentially prevent and improve the outcome of stroke.

Knowledge on the action to be taken and recognition of symptoms of stroke in a community: findings from the May Measurement Month 2017 blood pressure screening Programme in Malaysia

Background

Information regarding the knowledge on the action to be taken during stroke and good recognition of stroke symptoms is mandatory in helping to plan out educational strategies to deliver health education to the community.

Methods

This is a cross-sectional study of adults aged 18 and above attending a blood pressure screening program in community in conjunction with May Measurement Month 2017 in Malaysia. A structured self-administered questionnaire was given to the participants who gave verbal consent. Data analysis was done using SPSS v. 23 and multiple logistic regression was used to identify the determinants of knowledge on actions to be taken during stroke and recognition of stroke symptoms.

Results

Out of 4096 respondents, 82.9–92.1% of them able to recognise the common stroke symptoms. and 74.2% of the study respondents will go to hospital within 4.5 h of stroke onset. According to binomial logistic regression analyses, adults aged 45 years old and above (OR 1.39 95%CI 1.01–1.92), being Malay (OR 1.74, 95% CI 1.27–2.40), being non-smokers (OR = 2.491, 95% CI: 1.64–3.78), hypertensives (OR: 1.57, 95% CI: 1.02–2.42)and diabetics (OR: 2.54, 95% CI:1.38–4.69) are determinants of right actions to be taken during stroke. Meanwhile, respondents aged 45 years old and older (OR = 1.68, 95% CI: 1.39–2.03), being Malay (OR = 1.49, 95% CI: 1.24–1.79), hypertensive (OR = 1.32, 95% CI: 1.04–1.66) and those who had a previous history of stroke (OR = 2.25, 95% CI: 1.01–5.00) are determinants of good recognition of stroke symptoms.

Conclusions

The overall knowledge of stroke in our study population was good. Older age, being Malay, non-smokers, hypertensives and diabetics are determinants of right actions to be taken during stroke. Meanwhile, older age, being Malay, hypertensive and those who had a previous history of stroke are determinants of good recognition of stroke symptoms.

Stroke-Related Knowledge and Lifestyle Behavior among Stroke Survivors

AIMS

Awareness of stroke symptoms and risk factors, and actions taken in order to reduce the risk of new stroke events, should be of great importance among stroke survivors. The aims of this study were to assess changes in stroke-related knowledge and lifestyle behavior among patients experiencing a cerebrovascular event, and to assess the agreement between the patients' self-reported diagnosis, and the discharge diagnosis.

METHODS

All patients discharged with a diagnosis of stroke or transient ischemic attack during a 1-year period, received postal survey questionnaires at 3 and 12 months after discharge. The questionnaires included questions about symptom knowledge, lifestyle behavior, and patients were asked to report on their diagnosis.

RESULTS

A total of 282 patients were included (mean age 71.8 years, 57.1% men). Self-reported symptom knowledge was increased at 3 months (P < .001), and this persisted at 12 months. There was a poor correlation (r = .082; P = .171) between increasing symptom knowledge and stated lifestyle behavior changes. In all, 63% of the respondents correctly identified their own cerebrovascular subtype. Thirty-seven percent had quit smoking after 12 months, 30% reported that they used less sugary items, and 26% used less fatty food after the cerebrovascular event.

CONCLUSIONS

Stroke survivors reported increased stroke symptoms knowledge after 3 and 12 months. A proportion of patients made changes in lifestyle behavior. Only 2 out of 3 patients correctly identified their own cerebrovascular subtype, indicating room for improvement in clinical practice when informing and communicating with stroke and transient ischemic attack patients about their diagnosis.

Hospital distance, socioeconomic status, and timely treatment of ischemic stroke

OBJECTIVE

To determine whether lower socioeconomic status (SES) and longer home to hospital driving time are associated with reductions in tissue plasminogen activator (tPA) administration and timeliness of the treatment.

METHODS

We conducted a retrospective observational study using data from the Get With The Guidelines-Stroke Registry (GWTG-Stroke) between January 2015 and March 2017. The study included 118,683 ischemic stroke patients age ≥18 who were transported by emergency medical services to one of 1,489 US hospitals. We defined each patient's SES based on zip code median household income. We calculated the driving time between each patient's home zip code and the hospital where he or she was treated using the Google Maps Directions Application Programing Interface. The primary outcomes were tPA administration and onset-to-arrival time (OTA). Outcomes were analyzed using hierarchical multivariable logistic regression models.

RESULTS

SES was not associated with OTA (p = 0.31) or tPA administration (p = 0.47), but was associated with the secondary outcomes of onset-to-treatment time (OTT) (p = 0.0160) and in-hospital mortality (p = 0.0037), with higher SES associated with shorter OTT and lower in-hospital mortality. Driving time was associated with tPA administration (p < 0.001) and OTA (p < 0.0001), with lower odds of tPA (0.83, 0.79-0.88) and longer OTA (1.30, 1.24-1.35) in patients with the longest vs shortest driving time quartiles. Lower SES quintiles were associated with slightly longer driving time quartiles (p = 0.0029), but there was no interaction between the SES and driving time for either OTA (p = 0.1145) or tPA (p = 0.6103).

CONCLUSIONS

Longer driving times were associated with lower odds of tPA administration and longer OTA; however, SES did not modify these associations.

Stress in Patients With (Un)ruptured Intracranial Aneurysms vs Population-Based Controls

BACKGROUND

Stress is associated with increased risk of stroke and might predispose to presence and rupture of intracranial aneurysms.

OBJECTIVE

To study the association of recent and lifelong stress with unruptured intracranial aneurysm (UIA) and aneurysmal subarachnoid hemorrhage (ASAH).

METHODS

In 227 UIA patients (mean age 61 ± 11 yr), 490 ASAH patients (59 ± 11 yr), and 775 controls (51 ± 15 yr) who were randomly retrieved from the general population, we assessed occurrence of major life events and perceived stress during the preceding 12 mo and the entire life. With multivariable logistic regression analysis, we calculated odds ratios (ORs) with 95% confidence intervals (95% CIs) for 4 categories of life events (financial-related, work-related, children-related, and death of family members) and for periods of perceived stress at home and at work (never vs sometimes, often, or always). We adjusted for sex, age, alcohol consumption, smoking, and hypertension.

RESULTS

The 4 categories of life events and perceived stress at work had ORs ranging from 0.4 to 1.7, of which financial stress for UIA was statistically significant (95% CI: 1.1-2.5). ORs for chronic perceived stress at home in the previous year were 4.3 (95% CI: 1.8-10.3) for UIA and 2.5 (1.2-5.5) for ASAH, and for lifelong exposure 5.7 (2.2-14.5) for UIA and 3.0 (1.3-7.0) for ASAH.

CONCLUSION

For some components of stress, there may be a relation with UIA and ASAH. The mechanisms underlying this relation should be unraveled; strategies to improve coping with stress may reduce the risk of rupture in patients with unruptured aneurysms.

Increasing Stroke Knowledge and Decreasing Stroke Risk in a Latino Immigrant Population

Stroke knowledge is poor and stroke risk is growing for the U.S. Latino immigrant population. We present results of an evaluation of a tailored, community-based intervention in Durham, North Carolina. The intervention included integration of stroke knowledge into classes and workshops at a community-based organization. Knowledge surveys were administered to participants immediately before and after stroke education, and at multiple points over the following year. For both low-risk participants receiving classroom-based education and individually care managed participants with risk factors, stroke knowledge improved dramatically and remained high among those who could be reached for follow-up. Evidence of behavior change and change in clinical status was weak. These findings from an observational study conducted in a real-world context complement the results of previously reported efficacy studies, indicating potential gains from health education for Latino immigrants, even from classroom-based education for low-risk individuals.

Why are acute ischemic stroke patients not receiving thrombolysis in a telestroke network?

OBJECTIVE

The purpose of this study was to determine reasons for not giving intravenous tissue plasminogen activator to eligible patients with acute ischemic stroke in a telestroke network.

METHODS

We performed a retrospective analysis of prospectively collected data of patients who were seen as a telestroke consultation during 2015 and 2016 with the Arkansas Stroke Assistance through Virtual Emergency Support programme for possible acute ischemic stroke.

RESULTS

Total consultations seen were 809 in 2015 and 744 in 2016, out of which 238 patients in 2015 and 247 patients in 2016 received intravenous tissue plasminogen activator. In 2015 and 2016, out of the remaining 571 and 497 patients, 294 and 200 patients respectively were thought to be cases of acute stroke based on clinical evaluation. The most common reasons for not being treated in 2015 and 2016, respectively, were; (a) minimal deficits in 42.17% and 49.5% cases, (b) falling out of the 4.5-hour time window in 22.44% and 22% cases, (c) patient/next of kin refusal in 18.02% and 16.5% cases. Less common reasons included limited functional status, abnormal labs (thrombocytopenia, elevated international normalised ratio (INR)/prothrombin time (PT)/partial thromboplastin time (PTT), hypo or hyperglycemia etc), recent surgery and symptoms being too severe etc.

CONCLUSION

'Minimal deficits' and 'out of time window' continue to be the major causes for not receiving thrombolysis during acute ischemic stroke in both traditional and telestroke systems. Patient/next of kin refusal was high in our telestroke system when compared to traditional practices. Considering the increasing utility of telestroke this needs to be further looked into, along with the ways to address it.

Recognition of Stroke Warning Signs and Risk Factors Among Rural Population in Central Pennsylvania

BACKGROUND

Recognition of stroke warning signs and risk factors reduces prehospital delay and increases stroke survival. The goal of this study was to evaluate the public knowledge of stroke warning signs and risk factors in a rural area in Central Pennsylvania.

MATERIALS AND METHODS

In this study, the 2016 Sullivan County Health Fair attendees in central Pennsylvania answered a structured close-ended multiple choice questionnaire about stroke warning signs and risk factors. Further questions were asked about their reaction to acute stroke, the source of their stroke knowledge, and if they had personally known a stroke victim.

RESULTS

Out of 163 respondents, 85.3% selected ≥3 (out of 4) correct stroke warning signs and 71.8% of respondents selected ≥3 (out of 5) correct stroke risk factors. Regarding the wrong stroke warning signs, 34.4% mentioned neck pain followed by chest pain (33.1%). Identification of ≥1 (out of 3) wrong stroke warning signs were significantly lower among the respondents of postgraduate level education in comparison with other literacy groups. 95.7% of respondents chose "call 911 immediately" in response to an acute stroke. A relative with a history of stroke was the most cited source of information. Multivariate analysis found that a high level of education increases odds of recognition of ≥3 correct stroke risk factors (0.21; 95% confidence interval, 0.09-0.61). Knowing anyone with stroke was associated with an awareness of the life-threatening nature of stroke (r = 0.21, P < 0.01).

CONCLUSION

Respondents' recognition of stroke warning signs was favorable. About 85% of respondents recognized at least three stroke warning signs with no significant age and literacy effect. Our results provide evidence that the subjects most at risk of stroke are those with the least awareness of stroke risk factors.

Acute stroke patients' knowledge of stroke at discharge in China: a cross-sectional study

OBJECTIVES

A good mastery of stroke-related knowledge can be of great benefit in developing healthy behaviours. This study surveyed the knowledge about stroke and influencing factors among patients with acute ischaemic stroke (AIS) at discharge in a Chinese province.

METHODS

A cross-section study was conducted from November 1, 2014 to January 31, 2015. A total of 1531 AIS patients in Hubei Province completed a questionnaire at discharge. Multivariate linear regression was used to identify the influencing factors of their knowledge of stroke.

RESULTS

About 31.2% of the respondents did not know that stroke is caused by blockage or rupture of cerebral blood vessels and 20.3% did not realise they need immediate medical attention after onset. Approximately 50% did not know that sudden blurred vision, dizziness, headache and unconsciousness are the warning signs of stroke. Over 40% were not aware of the risk factors of the condition, such as hypertension, hyperlipidaemia, diabetes mellitus, smoking and obesity. Over 20% had no idea that they need long-term medication and strict control of blood pressure, blood lipids and blood sugar. Their knowledge levels were correlated with regions of residence (P < 0.0001), socioeconomic status (P < 0.05), physical condition (P < 0.01), previous stroke (P < 0.0001) and family members and friends having had a stroke (P < 0.01).

CONCLUSIONS

Most AIS patients in Hubei Province, China, had little knowledge of stroke at discharge. Further efforts should be devoted to strengthening the in-hospital education of stroke patients, especially those with a low income and those from rural areas.

Does stroke health promotion increase awareness of appropriate behavioural response? Impact of the face, arm, speech and time (FAST) campaign on population knowledge of stroke risk factors, warning signs and emergency response

INTRODUCTION

Inability to identify stroke warning signs accurately is an important cause of delay in seeking medical attention, leading to potential ineligibility for acute intervention. We report on post-campaign findings (wave 2) of national surveys to estimate changes in population knowledge following a media-based Face, Arm, Speech, Time stroke awareness campaign, comparing findings to those of a pre-campaign population survey (wave 1).Participants and methods: One thousand and ten randomly selected adults (18+) completed the Stroke Awareness Questionnaire on knowledge of warning signs, risk factors and response to stroke at wave 2 and findings were compared to wave 1 survey results. Logistic regression was used to examine the association between demographic characteristics and self-reported risk factors with knowledge of stroke and emergency response.

RESULTS

No significant differences existed in the ability of respondents to define stroke or to identify two or more stroke risk factors between waves 1 and 2 surveys (71% and 70%, respectively). Respondents to the wave 2 survey were five times more likely (odds ratio 4.9, p < .001) than those responding at wave 1 to know at least two warning signs of stroke (67% vs. 31%, respectively), specifically those targeted by the Face, Arm, Speech, Time campaign. While significant improvement in intention to call an ambulance was noted (odds ratio 1.5, p < .001, 57% at wave 2 compared to 47% at wave 1), for almost half of respondents (43%) this would not have been their first response to stroke. Less than 5% of respondents to both surveys identified thrombolysis as an emergency treatment for stroke (3.9% at wave 2 compared to 1.8% at wave 1).

DISCUSSION

Although significant improvements were made in several areas of stroke knowledge and intended response, awareness of acute stroke interventions was poor and intended behavioural response was suboptimal.

CONCLUSION

Findings from this study indicate need for targeted campaigns to improve population understanding of the reasons underlying the importance of rapid emergency response to stroke.

Knowledge about Stroke in Belo Horizonte, Brazil: A Community-Based Study Using an Innovative Video Approach

BACKGROUND AND PURPOSE

Stroke is a leading cause of death in Brazil. Knowledge about the clinical manifestations of stroke as well as its risk factors and its management is still poor in the country. We intended to assess the stroke knowledge of an urban population in Belo Ho-rizonte, Brazil.

METHODS

Individuals assisted by a basic health unit were interviewed between February and August 2014. After demographic data collection, the participants were asked to watch a video that consisted of a person presenting stroke signals and they were asked to answer questions about the condition shown on the video. Afterwards, they answered a semi-structured questionnaire to evaluate their stroke knowledge.

RESULTS

A total of 703 people were interviewed (62.1% female, mean age 46.7 years). Recognition of a person having a stroke on the presented video was achieved by 56.1% of the subjects. Female sex (p = 0.029) and contact with someone who had had a stroke (family member [p < 0.01], neighbor [p < 0.05]) increased the odds of correctly identifying the condition showed on the video. The most commonly mentioned clinical manifestations of stroke were weakness (34.7%) and speech disturbance (31.6%). Stroke risk factors that were most named were "unbalanced diet" (42.3%) and hypertension (33.7%). Most participants (66.8%) said they would call the emergency medical services, while 17.8% would go directly to a hospital. Only 17 subjects knew thrombolytic therapy for acute stroke.

CONCLUSION

Female sex and a family history of stroke increased the odds of recognizing the signs of stroke. Knowledge about the clinical manifestations, risk factors, and management of stroke was low in the studied population.

Undertreatment of Vascular Risk Factors in Patients with Monocular Ischaemic Visual Loss

Background and Purpose: Ischaemic visual loss is often considered a lower risk factor than other transient ischaemic attacks (TIA). We aimed to determine the recurrence risk, prevalence and management of vascular risk factors in these patients. Methods: The study took place in the University College Hospital London daily TIA clinic, main referral centre for North-Central London and Moorfields Eye Hospital. Consecutive records for patients with transient (< 24 h) or permanent (> 24 h) ischaemic visual loss were reviewed during the period January 2014–October 2016. Patients diagnosed with temporal arteritis were excluded. Results: Of 400 patients, 224 (56%) were male with mean age 64.5 years (SD 15.1); 263 patients (65.8%) presented with transient and 137 patients (34.2%) with permanent ischaemic visual loss; 51.3% had hypertension (HTN), 35.3% hypercholesterolaemia, 14.5% diabetes, 11.8% ischaemic ocular events, 10.0% ischaemic heart disease, 7.3% atrial fibrillation (AF), 6.3% TIA, 5.3% stroke, and 12.3% were smokers. Median vascular risk factors were 2 (range 1–6), but 122 (30.5%) had ≥3. Those with diabetes (p < 0.001), HTN (p = 0.008), previous myocardial infarction (p = 0.005), or ≥3 vascular risk factors (p = 0.012) were more likely to present with permanent visual loss, while patients with history of transient events, TIA (p = 0.002), or ocular (p = 0.002) presented with transient visual loss. Ninety-day recurrence was 10.5%; this was higher in patients with ≥3 risk factors (hazard ratio 1.42, 95% CI 0.95–2.11, p = 0.111). Patients with past TIA were more likely to be on secondary prevention than those with ocular ischaemia; 60.0 vs. 34.1% received antiplatelets and 76.0 vs. 43.9% statins. At presentation, only 55.2% (16 patients) with known AF were anticoagulated, despite all of them having CHADSVASC ≥1. Conclusions: Approximately one-third of patients with ocular ischaemia had ≥3 vascular risk factors with recurrences higher in these patients. Yet only half of those with previous ischaemic ocular events were on antiplatelets or statins. These patients should be investigated and treated as aggressively as other forms of TIA or stroke.

Efficacy of a Chronic Care-Based Intervention on Secondary Stroke Prevention Among Vulnerable Stroke Survivors: A Randomized Controlled Trial

BACKGROUND

Disparities of care among stroke survivors are well documented. Effective interventions to improve recurrent stroke preventative care in vulnerable populations are lacking.

METHODS AND RESULTS

In a randomized controlled trial, we tested the efficacy of components of a chronic care model-based intervention versus usual care among 404 subjects having an ischemic stroke or transient ischemic attack within 90 days of enrollment and receiving care within the Los Angeles public healthcare system. Subjects had baseline systolic blood pressure (SBP) ≥120 mm Hg. The intervention included a nurse practitioner/physician assistant care manager, group clinics, self-management support, report cards, decision support, and ongoing care coordination. Outcomes were collected at 3, 8, and 12 months, analyzed as intention-to-treat, and used repeated-measures mixed-effects models. Change in SBP was the primary outcome. Low-density lipoprotein reduction, antithrombotic medication use, smoking cessation, and physical activity were secondary outcomes. Average age was 57 years; 18% were of black race; 69% were of Hispanic ethnicity. Mean baseline SBP was 150 mm Hg in both arms. SBP decreased to 17 mm Hg in the intervention arm and 14 mm Hg in the usual care arm; the between-arm difference was not significant (-3.6 mm Hg; 95% confidence interval, -9.2 to 2.2). Among secondary outcomes, the only significant difference was that persons in the intervention arm were more likely to lower their low-density lipoprotein <100 md/dL (2.0 odds ratio; 95% confidence interval, 1.1-3.5).

CONCLUSIONS

This intervention did not improve SBP control beyond that attained in usual care among vulnerable stroke survivors. A community-centered component could strengthen the intervention impact.
