Stroke warning campaigns: delivering better patient outcomes? A systematic review

Addressing Disparities in Acute Stroke Management and Prognosis

There are now abundant data demonstrating disparities in acute stroke management and prognosis; however, interventions to reduce these disparities remain limited. This special report aims to provide a critical review of the current landscape of disparities in acute stroke care and highlight opportunities to use implementation science to reduce disparities throughout the early care continuum. In the prehospital setting, stroke symptom recognition campaigns that have been successful in reducing prehospital delays used a multilevel approach to education, including mass media, culturally tailored community education, and professional education. The mobile stroke unit is an organizational intervention that has the potential to provide more equitable access to timely thrombolysis and thrombectomy treatments. In the hospital setting, interventions to address implicit biases among health care providers in acute stroke care decision-making are urgently needed as part of a multifaceted approach to advance stroke equity. Implementing stroke systems of care interventions, such as evidence-based stroke care protocols at designated stroke centers, can have a broader public health impact and may help reduce geographic, racial, and ethnic disparities in stroke care, although further research is needed. The long-term impact of disparities in acute stroke care cannot be underestimated. The consistent trend of longer time to treatment for Black and Hispanic people experiencing stroke has direct implications on long-term disability and independence after stroke. A learning health system model may help expedite the translation of evidence-based interventions into clinical practice to reduce disparities in stroke care.

Prehospital stroke care in Singapore

ABSTRACT

Due to the narrow window of opportunity for stroke therapeutics to be employed, effectiveness of stroke care systems is predicated on the efficiency of prehospital stroke systems. A robust prehospital stroke system of care that provides a rapid and well-coordinated response maximises favourable poststroke outcomes, but achieving this presents a unique set of challenges dependent on demographic and geographical circumstances. Set in the context of a highly urbanised first-world nation with a rising burden of stroke, Singapore's prehospital stroke system has evolved to reflect the environment in which it operates. This review aims to characterise the current state of prehospital stroke care in Singapore, covering prehospital aspects of the stroke survival chain from symptom onset till arrival at the emergency department. We identify areas for improvement and innovation, as well as provide insights into the possible future of prehospital stroke care in Singapore.

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.

Perceived performance of activities of daily living by stroke patients: key in decision to call EMS and outcomes

Background

Until recently, public education campaigns aimed at improving help-seeking behavior by acute stroke patients have achieved only limited or even no effects. Better understanding of psychological factors determining help-seeking behavior may be relevant in the design of more effective future campaigns.

Methods

In this prospective, cross-sectional study, we interviewed 669 acute stroke patients within 72 h after hospital admission. The primary endpoint was the effect of psychological factors on the decision to call emergency medical services (EMS). Secondary endpoints were the effects of such factors on treatment rates and clinical improvement (difference between modified Rankin scale (MRS) scores at admission and at discharge).

Results

Only 48.7% of the study population called the EMS. Multivariate logistic and linear regression analyses revealed that perception of unimpaired performance of activities of daily living (ADL) was the only psychological factor that predicted EMS use and outcomes. Thus, patients who perceived only minor impairment in performing ADL were less likely to use EMS (odds ratio, 0.54 [95% confidence interval, 0.38-0.76]; p = 0.001), had lower treatment rates, and had less improvement in MRS scores (b = 0.40, p = 0.004). Additional serial mediation analyses involving ischemic stroke patients showed that perception of low impairment in ADL decreased the likelihood of EMS notification, thereby increasing prehospital delays, leading to reduced thrombolysis rates and, finally, to reduced clinical improvement.

Conclusion

Perception of unimpaired performance of ADL is a crucial barrier to appropriate help-seeking behavior after acute stroke, leading to undertreatment and less improvement in clinical symptoms. Thus, beyond improving the public's knowledge of stroke symptoms, future public education campaigns should focus on the need for calling the EMS in case of stroke symptoms even if daily activities do not seem to be severely impaired.

Prevalence and determinants of delays in care among premature deaths due to acute cardiac conditions and stroke in residents of a district in India

Background

Lack of timely care is a predictor of poor outcomes in acute cardiovascular emergencies including stroke. We assessed the presence of delay in seeking appropriate care among those who died due to cardiac/stroke emergencies in a community in northern India and identified the reasons and determinants of this delay.

Methods

We conducted a social audit among all civil-registered premature (30-69 years) deaths due to acute cardiac event or stroke in the district. The three-delays model was used to qualitatively classify the delays in care-seeking-deciding to seek care, reaching the appropriate health facility (AHF) and initiating definitive treatment. Based on the estimated time from symptom onset to reaching AHF, we classified patients as early (reached within one hour) or delayed arrivers. We used mixed-effect logistic regression with postal code as a random effect to identify determinants of delayed arrival.

Findings

Only 10.8% of the deceased reached an AHF within one hour. We noted level-1 delay in 38.4% (60% due to non-recognition of seriousness); level-2 delay in 20% (40% due to going to an inappropriate facility) and level-3 delay in 10.8% (57% due to lack of affordability). Patients with a monthly family income of >270US$ (aOR 0.44; 95% CI 0.21-0.93) were less and those staying farther from AHF (aOR 1.12; 95% CI 1.01-1.25 for each Km) were more likely to have delayed arrival in AHF.

Interpretation

A small proportion of patients with cardiac and stroke emergencies reach health facility early with delays at multiple levels. Addressing the reasons for delay could prevent these deaths.

Central Retinal Artery Occlusion: Time to Presentation and Diagnosis

OBJECTIVE

To evaluate the presentation patterns of patients diagnosed with central retinal artery occlusion (CRAO) from 2011 to 2020.

DESIGN

Retrospective cohort study SUBJECTS: The present study was conducted in 484 patients presenting within 30 days of symptom onset with accurate documentation of time of symptom onset, time of presentation to the health care system, and time of presentation to an ophthalmologist.

METHODS

An independent chart review of patients with CRAO was conducted.

MAIN OUTCOME MEASURES

Demographic information including age, sex, and race were collected. Presentation patterns such as time of first symptoms, time of first contact with the health care system, and time of evaluation by an ophthalmologist were analyzed. Additionally, information regarding the medical venue or specialty of initial patient contact was collected.

RESULTS

A total of 247 (51%) patients contacted the health care system within 4.5 hours of system onset, whereas 86 (17.8%) patients waited over 24 hours. Only 81 (32.8%) of the 247 patients who presented within 4.5 hours saw an ophthalmologist within that time frame, whereas 172 (35.5%) of the entire cohort of 484 did not present to an ophthalmologist within 24 hours of vision loss. There was significant variability with regards to medical specialty of initial patient contact, with 292 (60.3%) patients first presenting to an emergency department and 133 (27.5%) patients first presenting to an ophthalmologist. Black and Hispanic patients presented later than patients of White, Asian, or other racial backgrounds (40.4 ± 10.2 hours versus 23.0 ± 3.4 hours, P = 0.05).

CONCLUSIONS

Although no level 1 evidence-based treatment is currently available for CRAO, thrombolytic therapy may be promising. Even though over half of patients with CRAO within our institution connected with the health care system within a potential window for thrombolytic therapy, most did not receive a definitive ophthalmic diagnosis within that time frame. Public health educational campaigns and infrastructure optimization must speed up presentation times, decrease the time to ophthalmic diagnosis, and target vulnerable populations to offer and research timely administration of thrombolytic therapy.

Trends of recanalization therapies and state of art for ischemic stroke treatment in Campania region, Italy

Background

According to the last Italian report by the Ministry of Health in 2018, the estimated number of acute ischemic strokes (AIS) in Campania is 10,000/year, with an expected number of 1390 intravenous thrombolysis (IVT) and 694 mechanical thrombectomies (MT). In 2017, only 1.5% of expected patients received IVT and 0.2% MT. This study analyzed the trend of IVT and MT in 2019–2020 and depicted the state of art of Stroke Care in Campania.

Methods

From the regional health task force, we obtained the hospital discharge forms from all private and public hospitals in Campania; we selected patients with a principal diagnosis of AIS and measured the rate of patients admitted to neurology units and the rate of IVT, MT, and IVT + MT for both 2019 and 2020.

Results

In 2019, we observed 4817 admissions for AIS; 2858/4817 (59.3%) patients were admitted to neurology units. Out of 4817 patients, 192 received IVT, 165 MT, and 131 IVT + MT (488 treated patients; 10.1%). In 2020, we observed 4129 admissions for AIS; 2502/4129 (62.7%) patients were admitted to neurology units. Out of 4129 patients, 198 received IVT, 250 MT, and 180 IVT + MT (628 treated patients; 15.2%). These results showed that despite a reduction of AIS admissions in 2020, the relative and absolute rate of recanalization treatments increased. However, the number of patients who were not admitted to neurology units nor received acute treatments remained dramatically high.

Conclusion

Despite the development of acute treatments, the Campania Stroke Network still needs significative efforts to improve.

Perceptions of community members on contextual factors driving cardiovascular disease behavioural risk in Ghana: a qualitative study

Background

There is clear evidence that lifestyle interventions are effective towards reducing cardiovascular risk. However, implementing these interventions in real-world setting has been suboptimal, especially in sub-Saharan Africa, thus creating ‘evidence to practice gap.’ We explore perceptions of community members on contextual factors driving cardiovascular disease (CVD) behavioural risk (alcohol consumption, smoking, physical (in)activity and fruits and vegetables consumption) in Ghana.

Methods

This was a cross-sectional study. Thirty (30) focus group discussions (FGDs) were carried out in five communities in Ghana (Ga Mashie, Tafo, Gyegyeano, Chanshegu and Agorve) between October and November 2017, and these were analysed using a thematic approach.

Results

Five main factors were raised by participants as contextual factors driving alcohol consumption and smoking and these include economic (poverty, unemployment, loss of jobs), psycho-social (worries, hardships, anxieties), medical (pain suppression, illness management), sexual (sexual performance boost), and socio-cultural (curse invocation, quest for supernatural powers) factors. Personal/social factors (time constraints, personal dislike, lack of knowledge of the benefits of exercise), economic factors (poverty, economic hardship), and negative health effects (getting tired easily, medical conditions) were cited as reasons why community members did not engage in physical activity. Consumption of fruits and vegetables in the five communities were determined by availability, cost, personal (dis)like, lack of knowledge about benefits, and cultural taboo. Participants’ narratives revealed that the symbolic functions of some of these behavioural risk factors and the built environment were important determining factors that have sustained these behaviours in these communities over the years.

Conclusions

This study showed that successful implementation of CVD interventions in Ghana needs to address the perceptions of community members on factors driving CVD behavioural risk factors. Future policies and interventions should be developed based on these contextual factors taking into consideration the age, sex and ethnic variations especially with interventions seeking to address CVD risk factors at the primary health care level. These findings should urge local policy makers and health managers to incorporate the roles of these contextual factors in new programs targeting cardiovascular health. Closing the ‘evidence to practice’ gap as far as CVD interventions are concerned may be impossible without this.

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.

Temporal Trend of Transient Ischemic Attack Management over a 10-Year Period: Data from the Rhône County, France

BACKGROUND

Timely recognition and management of transient ischemic attack (TIA) offer the greatest opportunity to prevent subsequent stroke. But variability of TIA management quality exists across hospitals. Under the impetus of national plans, measures were adopted to improve TIA management, including a structured local pathway. Our objective was to compare TIA management between two periods over 10 years, before and after the implementation of these measures.

METHODS

A before-and-after study was conducted with two identical population-based cohort studies in 2006-2007 (AVC69) and 2015-2016 (STROKE69) including all patients with TIA diagnosis over a 7-month period in six public and private hospitals in the Rhône county in France. The primary outcome was the adequate TIA management defined as brain and vessel imaging within 24 h of admission and the prescription of antithrombotic treatment at discharge.

RESULTS

We identified 109 patients TIA patients in 2006-2007, and 458 over the same period in 2015-2016. A higher proportion of patients were adequately managed in 2015-2016 compared to 2006-2007 (14/96 [15%] in 2006-2007 vs. 306/452 [68%] in 2015-2016, p < 0.001). This difference was mainly driven by a marked increase of vessel imaging performed within 24 h of admission, most often by computed tomography angiography. Furthermore, patients called more often emergency medical dispatch before admission, were admitted with a shorter delay after symptom onset, and were more likely discharged to home in 2015-2016 compared to 2006-2007.

CONCLUSION

Our study demonstrated an increasing rate of adequate TIA management, mainly driven by a marked increase of vessel imaging within 24 h of admission, over a 10-year period in the Rhône county in France.

Impact of a health campaign on Chinese public awareness of stroke: evidence from internet search data

INTRODUCTION

Health campaigns have the potential to improve public awareness, but their impact can be difficult to assess. Internet search data provide information concerning online health information-seeking behaviour in the population and may serve as a proxy for public awareness to evaluate health campaigns. This study aimed to measure the impact of World Stroke Day (WSD) in China using Baidu search data.

METHODS

Daily search index values (SIV) for the term 'stroke' were collected from January 2011 to December 2019 using the Baidu Index platform. We examined the mean difference in SIV between the 4 weeks surrounding WSD (period of interest) and the rest of the year (control period) for each year by t-test analysis. The mean difference between the period of interest and the control period was also calculated. The joinpoint regression model was used to analyse the trends of internet search activity 30 days before and after WSD for each year (2011-2019). Finally, the top and rising queries related to stroke during the week of the campaign in 2020 were summarised.

RESULTS

A significant mean increase in SIV of 418.5 (95% CI: 298.8 to 538.2) for the period of interest surrounding WSD was observed, 36.2% greater than the SIV during the control period (2011-2019). Short-term joinpoint analysis showed a significant increase in SIV 3 days before WSD, a peak on WSD and a decrease to the precampaign level 3 days after WSD. The rising related queries suggested that the public had increasing concerns about stroke warning signs, stroke prevention and stroke recovery during the campaign.

CONCLUSIONS

The WSD campaign increased internet search activity. These research techniques can be applied to evaluation of other health campaigns. Advancing understanding of public demand will enable tailoring of the campaign and strengthen health management.

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.

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.

Public Stroke Knowledge, Awareness, and Response to Acute Stroke in Isfahan Iran: What is Less or Misinterpreted in Developing Countries

BACKGROUND

Considering the high burden of stroke in developing countries, it is important for the community to have adequate information and awareness of this disease. In this study, the baseline knowledge of an Iranian population towards stroke has been evaluated.

METHOD

This study was conducted in a governmental hospital in Isfahan, Iran. The participants were selected from the companions of non-cardio-vascular hospitalized patients. A self-administered questionnaire was designed for gathering information RESULTS: A total of 630 questionnaires were analysed. Hypertension and stress were the most frequently identified risk factors (recognised by 83.7% and 75.8% respectively), while pregnancy, oral contraceptives, and anti-coagulants were the least (recognised by 3.5%, 14.2% and 15.8% respectively). Knowledge of other important risk factors such as cardiac diseases was also relatively low (39.4%). Sudden visual difficulties and irrelevant speech were the least identified warning signs of stroke (45.3% and 34.6% respectively), however, knowledge towards all other warning signs was moderately good (each identified by 60-70%). Importantly only 44.2% of respondents were aware that stroke treatment should be started within the first 3 hours. Participants tended to have moderately good insight of most stroke complications and rehabilitation (60-70%). Urban residence, high level of education and knowing someone with a history of stroke were significant predictors of a higher level of stroke awareness.

CONCLUSION

The findings of this study indicate that there is a need to improve general knowledge of cardiac and hypercoagulable related risk factors. Furthermore, understanding of the importance of time critical stroke management and the ineffectiveness of traditional medicine needs to be raised in the general community.

Using Google Trends to assess the impact of Global Public Health Days on online health information-seeking behaviour in Arabian Peninsula

Background

Global Public Health Days (GPHD) are public health interventions which serve to improve public awareness of specific health conditions. Google Trends is a publicly available tool that allows the user to view the popularity of a searched keyword during a specified time period and across a predetermined region. Our objective was to use Google Trends to assess the impact of four GPHD (World Heart Day, World Mental Health Day, World Diabetes Day and World Hypertension Day) on online health information-seeking behaviour (OHISB), 4 weeks before and a week after the GPHD, across six countries of the Arabian Peninsula (Bahrain, Kuwait, Oman, Qatar, Saudi Arabia and United Arab Emirates).

Methods

Relative Search Volume (RSV) was extracted for the aforementioned countries from 28 days before the GPHD and 7 days afterwards. Statistical analysis, undertaken using joinpoint regression software, showed that GPHD have significant changes for Saudi Arabia (Diabetes, Mental Health and Heart day) and UAE (Mental Health day) but were short-lived with a fall in RSV of up to 80% after peak interest.

Conclusion

GPHD appears to be effective in some countries while further research is needed to investigate the reason of its limitations.

Impact of a theory-informed and user-centered stroke information campaign on the public's behaviors, attitudes, and knowledge when facing acute stroke: a controlled before-and-after study

Background

Public awareness of stroke symptoms is a key factor to ensure access to reperfusion strategies in due time. We designed and launched a regional theory-informed and user-centered information campaign and assessed its impact on emergency medical services (EMS) calls for stroke suspicion, time-to-call, and public attitudes and awareness concerning stroke.

Methods

A controlled before-and-after study was conducted during 3 sequential time-periods in 2 separate counties. Key messages of the campaign were underpinned by stroke representations and the theory of planned behavior, and focused on recognition of stroke warning signs and the need to call EMS urgently. The campaign included posters, leaflets, adverts and films displayed in bus and subway stations, internet, social networks, and local radio. Outcome measures on behavior, attitudes, and knowledge were assessed before the launch of the campaign, at 3 months, and 12 months.

Results

The number of EMS calls for stroke suspicion increased by 21% at 12 months in the intervention county and this change was significantly different to that observed in the control county (p = 0.02). No significant changes were observed regarding self-reported attitudes in case of stroke. An 8% significant increase in recognizing at least 2 stroke warning signs was observed in the intervention county (p = 0.04) at 3 months, while it did not change significantly in the control county (p = 0.6). However, there was no significant difference in warning sign recognition between both counties (p = 0.16).

Conclusion

The campaign significantly improved public’s behavior of calling EMS, although stroke knowledge was not improved as much as expected. Repeating these campaigns over time might further help improve timeliness and access to reperfusion strategies.

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

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

Does socioeconomic position affect knowledge of the risk factors and warning signs of stroke in the WHO European region? A systematic literature review

Background

Strokes are one of the leading causes of death worldwide. People with a lower socioeconomic position (SEP) (i.e. with regards to education, income and occupation) are at a higher risk of having a stroke and have worse clinical outcomes compared to the general population. Good knowledge levels about stroke risk factors and warning signs are key to prolonging life and reducing health issues caused by stroke. This systematic review examined differences in knowledge of stroke risk factors and warning signs with regards to SEP in the WHO European region.

Methods

MEDLINE, Embase, Web of Science, PsycINFO and CINAHL were systematically searched using appropriate Medical Subject Headings (MeSH) terms and free text, combining search terms with Boolean operators. Two independent reviewers selected studies in two stages (title and abstract, and full-text), and screened reference lists of included studies. Only studies in English and based in the WHO European region were included.

Results

Screening identified 2118 records. In the final review, 20 articles were included, with 67,309 study participants between them. Out of 17 studies that looked at stroke risk factors, 11 found increasing knowledge to be associated with higher SEP, four found no difference by SEP, one showed a mixed pattern and one outlier study found increasing knowledge of risk factors to be associated with a lower SEP. Out of 19 studies that looked at stroke warning signs or symptoms, 15 found there to be better knowledge of warning signs with a higher SEP, three found there to be no difference, and the same outlier study found increasing knowledge of warning signs with a lower SEP. Studies that seemed to have a higher quality rating found increasing knowledge of stroke with a higher SEP. A meta-analysis was not possible due to heterogeneity of studies.

Conclusions

In the WHO European region, better knowledge of stroke risk factors and warning signs is associated with a higher SEP. Public health campaigns and educational interventions aiming to increase stroke knowledge should be targeted at people with a lower SEP.

A Community-Engaged Stroke Preparedness Intervention in Chicago

Background

We evaluated a community‐engaged stroke preparedness intervention that aimed to increase early hospital arrival and emergency medical services (EMS) utilization among patients with stroke in the South Side of Chicago, Illinois.

Methods and Results

We compared change in early hospital arrival (<3 hours from symptom onset) and EMS utilization before and after our intervention among patients with confirmed ischemic stroke at an intervention hospital on the South Side of Chicago with concurrent data from 6 hospitals in nonintervention communities on the North Side of Chicago and 17 hospitals in St Louis, Missouri. We assessed EMS utilization for suspected stroke secondarily, using geospatial information systems analysis of Chicago ambulance transports before and after our intervention. Among 21 497 patients with confirmed ischemic stroke across all sites, early arrival rates at the intervention hospital increased by 0.5% per month (95% CI, −0.2% to 1.2%) after intervention compared with the preintervention period but were not different from North Side Chicago hospitals (difference of −0.3% per month [95% CI, −0.12% to 0.06%]) or St Louis hospitals (difference of 0.7% per month [95% CI, −0.1% to 1.4%]). EMS utilization at the intervention hospital decreased by 0.8% per month (95% CI, −1.7% to 0.2%) but was not different from North Side Chicago hospitals (difference of 0.004% per month [95% CI, −1.1% to 1.1%]) or St Louis hospitals (difference of −0.7% per month [95% CI, −1.7% to 0.3%]). EMS utilization for suspected stroke increased in the areas surrounding the intervention hospital (odds ratio [OR], 1.4; 95% CI, 1.2–1.6) and in the South Side (OR, 1.2; 95% CI, 1.1–1.3), but not in the North Side (OR, 1.0; 95% CI, 0.9–1.1).

Conclusions

Following a community stroke preparedness intervention, early hospital arrival and EMS utilization for confirmed ischemic stroke did not increase. However, ambulance transports for suspected stroke increased in the intervention community compared with other regions.

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.

Planning a campaign to fight stroke: an educational pilot project in La Spezia, Italy

INTRODUCTION

Best medical treatments of ischemic stroke are admission to stroke unit, intravenous thrombolysis and, in selected cases, thrombectomy. Time from symptom onset to interventions is the best predictor of clinical outcome. In order to verify the effectiveness of an active education programme of awareness on the knowledge of stroke, we performed a local campaign "on the field".

SUBJECTS AND METHODS

We selected 101 subjects from the general population who took part in the "stroke awareness campaign" organised by the Italian Association for the fight against stroke (A.L.I.Ce). Mean age was 59 years (50% female; 50% male); 55% of the sample reported a high level of education (> 8 years: high school or university degree). After a short multiple-choice questionnaire, we administered a face-to-face standard educational protocol (15 min). The efficacy of that educational intervention was then verified after a period of 12 months, by telephone interview.

RESULTS

There was improvement both in the definition of stroke (66% vs. 92%, p < .001) and in recognizing symptoms and signs (19% vs. 72%, p < .001). Knowledge of the importance of stroke unit in the acute treatment of stroke did not improve, as it was already high on baseline (92% vs. 97%, p: n.s.). The improvement was evident in particular in younger and higher educated people, without difference in gender. There was no difference based on risk factor profiles of participants.

CONCLUSIONS

Our results suggest that a personalised education can improve knowledge on stroke symptoms and signs, independently of gender and personal risk factors. The results should be verified in larger and less selection population.

Evaluation of the Swedish National Stroke Campaign: A population-based time-series study

BACKGROUND

Time delay from stroke onset to hospital arrival is an important obstacle to recanalization therapy. To increase knowledge about stroke symptoms and potentially reduce delayed hospital arrival, a 27-month national public information campaign was conducted in Sweden.

AIM

To assess the effects of a national stroke campaign in Sweden.

METHODS

This nationwide study included 97,840 patients with acute stroke, admitted to hospital and registered in the Swedish Stroke Register from 1 October 2010 to 31 December 2014 (one year before the campaign started to one year after the campaign ended). End points were (1) proportion of patients arriving at hospital within 3 h of stroke onset and (2) the proportion < 80 years of age receiving recanalization therapy.

RESULTS

During the campaign, both the proportion of patients arriving at hospital within 3 h (p < 0.05) and the proportion receiving recanalization therapy (p < 0.001) increased. These proportions remained stable the year after the campaign, and no significant improvements with respect to the two end points were observed during the year preceding the campaign. In a multivariable logistic regression model comparing the last year of the campaign with the year preceding the campaign, the odds ratio of arriving at hospital within 3 h was 1.05 (95% confidence interval (CI): 1.00-1.09) and that of receiving recanalization was 1.34 (95% CI: 1.24-1.46).

CONCLUSION

The Swedish National Stroke Campaign was associated with a sustained increase in the proportion of patients receiving recanalization therapy and a small but significant improvement in the proportion arriving at hospital within 3 h.

Transferring Stroke Knowledge from Children to Parents: A Systematic Review and Meta-Analysis of Community Stroke Educational Programs

BACKGROUND

The purpose of this systematic review and meta-analysis on child-to-parent communication of stroke information (Child-Mediated Stroke Communication, CMSC) is to provide the highest levels of evidence supporting the role of this approach in community education.

METHODS

Databases such as PubMed, Google Scholar, PsycINFO, Web of Science, MEDLINE, and CINHAL were searched to gather information on CMSC followed by a meta-analysis. The eligibility criteria were as follows: (a) children aged 9-15years and parents, (b) randomized or nonrandomized trials, and (c) outcome variables that included the proportions of parents answering the pretest and post-test on stroke knowledge regarding risk factors, symptoms, and what to do in the event of stroke.

RESULTS

Of the 1668 retrieved studies, 9 articles were included. Meta-analytical findings yielded that the proportions of correct answers for stroke symptoms and its risk factors among parents were 0.686 (95% CI: 0.594-0.777) at baseline and increased to 0.847 (95% CI: 0.808-0.886) at immediate post-test and 0.845 (95% CI: 0.804-0.886) delayed post-test. The proportions of correct answers for behavioral intent to call 911 when witnessing stroke was 0.712 (95% CI: 0.578-0.846) at baseline, rising to 0.860 (95% CI: 0.767-0.953) at immediate post-test, and 0.846 (95% CI: 0.688-1.004) at delayed post-test.

CONCLUSIONS

CMSC is effective for educating families. More work is needed to increase the use of validated stroke literacy instruments and behavioral theory, and to reduce parental attrition in research studies.

Stroke 112: A Universal Stroke Awareness Program to Reduce Language and Response Barriers

BACKGROUND AND PURPOSE

To improve stroke awareness and reduce life-threatening prehospital delays worldwide, a universal stroke educational program is needed. To meet this unmet need, we developed a universal program without language barriers and tested its acceptance in Taiwan, where Chinese is the native language.

METHODS

Stroke 112 was developed using the universal emergency phone number, 112. The numbers imply an emergency and correspond to the 3 stroke recognition signs used in FAST (Face, Arm, Speech, and Time): 1 uneven face (crooked mouth); 1 weak arm (arm weakness); 2 incoherent lips (slurred speech). An online survey was used to determine the acceptance of the Stroke 112 program compared with that of FAST in Chinese. The surveys were delivered using SurveyMonkey (http://www.surveymonkey.com) on 2 separate occasions in Taiwan; in August 2017 for an initial estimation of the acceptance of Stroke 112 and in March 2018, 2 weeks after the official release of Stroke 112 in Taiwan, including a special introductory lecture for neurologists hosted by the STARS-Taiwan (Stroke Treatment and Research Society-Taiwan).

RESULTS

The initial survey with 465 survey responders, 54.6% thought that Stroke 112 was easier to remember for people in Taiwan compared with FAST (41.2%). After Stroke 112's official release in Taiwan, 610 individuals completed the survey, and the majority (66.4%) thought that Stroke 112 was easier to remember, a significant increase compared with the initial survey (P=0.0001). Among the 130 neurologists who attended the Stroke 112 introductory lecture, 55 completed the online survey. A greater acceptance of Stroke 112 (74.6%) compared with FAST (16.4%) was observed among these 55 neurologists (P=0.0001).

CONCLUSIONS

Stroke 112, a universal stroke educational program without language barriers was developed. It could potentially be implemented worldwide, especially where 112 is used as an emergency phone number.

Stroke Literacy in a South Brazilian City: A Community Based Survey

BACKGROUND

This community-based and cross-sectional study was performed in a Brazilian city and aimed to evaluate stroke literacy.

METHODS

A stroke knowledge survey was administered to passersby of a public square from December 2015 to October 2016, in Santa Maria, Rio Grande do Sul. Convenience sampling was performed.

RESULTS

A total of 633 respondents completed the survey. Of the respondents, 33% knew the meaning of "AVC"; 29.5% incorrectly localized stroke in the heart. Any warning sign of stroke (open-ended question) could not be remembered by 50.7% of the respondents; individuals with a higher level of schooling (>7 years of education) and those who localized stroke in the brain were more likely to call an emergency in the case of a stroke (adjusted odds ratio [OR] 1.040, 95% confidence interval [CI] 1.004-1.078 for years of schooling; adjusted OR 1.542, 95% CI 1.102-2.156 for replying "yes" to brain as the organ affected in stroke).

CONCLUSIONS

Brazilian public knowledge about stroke is still scarce, even in a population with levels of formal education above the national average or in a city where annual promotion of Stroke Awareness Campaigns have taken place for almost a decade. Thus, it might be necessary to design different informative strategies targeted to our study's population to improve stroke campaigns in Brazil. In Brazil, increasing awareness of stroke focused on stroke prevention and recognition of its warning signs should be a national priority in public health as the access to stroke treatment remains limited.

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.

Stroke identification by criteria based dispatch - a register based study

BACKGROUND

Rapid and precise dispatch of resources is a key element in pre-hospital emergency medicine. Emergency medical communication centres (EMCCs) dispatch resources based on protocols and guidelines, balancing the acute need of the individual and the resource allocation of the pre-hospital emergency medical system. The aim of this study was to determine the validity of stroke identification by the Norwegian dispatch guidelines.

METHOD AND MATERIAL

This was a register-based study where patients suspected for stroke were compared to those with the final diagnosis of stroke as an indicator group for the guideline validation. One EMCC and its three associated hospitals participated with 13 months of data. Four subcodes of the stroke dispatch code were defined as suspicious of stroke and further analysed. Factors associated with stroke identification were explored.

RESULTS

The sensitivity for identifying a stroke patient at initial EMCC contact was 57.9% (51.5, 64.1), specificity was 99.1% (98.9, 99.2), positive predictive value was 45.7% (40.1, 51.4) and negative predictive value was 99.4% (99.3, 99.5). The emergency medical access telephone (113) was initial EMCC contact line in only 48% of the cases. Paralyses and admittance to a smaller hospital were associated with increased probability for stroke (OR 2.6, P = 0.001 and OR 2.7, P = 0.01), respectively.

CONCLUSION

The sensitivity for identification of stroke patients by the dispatch guidelines is modest, while the specificity is high. The 113 telephone line was initial EMCC access point for less than half of the stroke patients.

Feasibility of a hyper-acute stroke unit model of care across England: a modelling analysis

OBJECTIVES

The policy of centralising hyperacute stroke units (HASUs) in England aims to provide stroke care in units that are both large enough to sustain expertise (>600 admissions/year) and dispersed enough to rapidly deliver time-critical treatments (<30 min maximum travel time). Currently, just over half (56%) of patients with stroke access care in such a unit. We sought to model national configurations of HASUs that would optimise both institutional size and geographical access to stroke care, to maximise the population benefit from the centralisation of stroke care.

DESIGN

Modelling of the effect of the national reconfiguration of stroke services. Optimal solutions were identified using a heuristic genetic algorithm.

SETTING

127 acute stroke services in England, serving a population of 54 million people.

PARTICIPANTS

238 887 emergency admissions with acute stroke over a 3-year period (2013-2015).

INTERVENTION

Modelled reconfigurations of HASUs optimised for institutional size and geographical access.

MAIN OUTCOME MEASURE

Travel distances and times to HASUs, proportion of patients attending a HASU with at least 600 admissions per year, and minimum and maximum HASU admissions.

RESULTS

Solutions were identified with 75-85 HASUs with annual stroke admissions in the range of 600-2000, which achieve up to 82% of patients attending a stroke unit within 30 min estimated travel time (with at least 95% and 98% of the patients being within 45 and 60 min travel time, respectively).

CONCLUSIONS

The reconfiguration of hyperacute stroke services in England could lead to all patients being treated in a HASU with between 600 and 2000 admissions per year. However, the proportion of patients within 30 min of a HASU would fall from over 90% to 80%-82%.

Community Interventions to Increase Stroke Preparedness and Acute Stroke Treatment Rates

PURPOSE OF REVIEW

Acute stroke treatments reduce the risk of post-stroke disability. These treatments, tissue plasminogen activator (tPA) and intra-arterial treatment, are highly time-dependent; thus, one of the main barriers to treatment is pre-hospital delay. Stroke preparedness is defined as the ability to recognize stroke symptoms and the intent to activate emergency medical services (EMS). This review describes types of acute stroke treatment and preparedness interventions, including recent mass media interventions to increase acute stroke treatment rates, and adult and youth community interventions to increase stroke preparedness.

RECENT FINDINGS

The mass media campaigns show mixed results regarding acute stroke treatment rates, possibly attributed to the various media platforms utilized and resources available. The adult and youth community interventions reveal an overall increase in stroke symptom recognition and behavioral intent to call EMS. However, most of these community interventions were not grounded in health behavior theory, and they were tested in single group, pre-post test study designs that assessed behavioral rather than clinical outcomes. The delivery of stroke preparedness information by youth to adults, for example via home assignments, is a promising and innovative approach to stroke preparedness. Mass media and community interventions show promise to increase stroke preparedness and acute stroke treatment rates. The development of health behavior theory-based interventions that are tested via scientifically rigorous study designs are needed to prioritize which interventions should be disseminated to culturally and socially similar communities.

Impact on Prehospital Delay of a Stroke Preparedness Campaign: A SW-RCT (Stepped-Wedge Cluster Randomized Controlled Trial)

BACKGROUND AND PURPOSE

Public campaigns to increase stroke preparedness have been tested in different contexts, showing contradictory results. We evaluated the effectiveness of a stroke campaign, designed specifically for the Italian population in reducing prehospital delay.

METHODS

According to an SW-RCT (Stepped-Wedge Cluster Randomized Controlled Trial) design, the campaign was launched in 4 provinces in the northern part of the region Emilia Romagna at 3-month intervals in randomized sequence. The units of analysis were the patients admitted to hospital, with stroke and transient ischemic attack, over a time period of 15 months, beginning 3 months before the intervention was launched in the first province to allow for baseline data collection. The proportion of early arrivals (within 2 hours of symptom onset) was the primary outcome. Thrombolysis rate and some behavioral end points were the secondary outcomes. Data were analyzed using a fixed-effect model, adjusting for cluster and time trends.

RESULTS

We enrolled 1622 patients, 912 exposed and 710 nonexposed to the campaign. The proportion of early access was nonsignificantly lower in exposed patients (354 [38.8%] versus 315 [44.4%]; adjusted odds ratio, 0.81; 95% confidence interval, 0.60-1.08; P=0.15). As for secondary end points, an increase was found for stroke recognition, which approximated but did not reach statistical significance (P=0.07).

CONCLUSIONS

Our campaign was not effective in reducing prehospital delay. Even if some limitations of the intervention, mainly in terms of duration, are taken into account, our study demonstrates that new communication strategies should be tested before large-scale implementation.

Development of an education campaign to reduce delays in pre-hospital response to stroke

Background

Systematic reviews call for well-designed trials with clearly described intervention components to support the effectiveness of educational campaigns to reduce patient delay in stroke presentation. We herein describe the systematic development process of a campaign aimed to increase stroke awareness and preparedness.

Methods

Campaign development followed Intervention Mapping (IM), a theory- and evidence-based tool, and was articulated in two phases: needs assessment and intervention development. In phase 1, two cross-sectional surveys were performed, one aiming to measure stroke awareness in the target population and the other to analyze the behavioral determinants of prehospital delay. In phase 2, a matrix of proximal program objectives was developed, theory-based intervention methods and practical strategies were selected and program components and materials produced.

Results

In phase 1, the survey on 202 citizens highlighted underestimation of symptom severity, as in only 44% of stroke situations respondents would choose to call the emergency service (EMS). In the survey on 393 consecutive patients, 55% presented over 2 hours after symptom onset; major determinants were deciding to call the general practitioner first and the reaction of the first person the patient called. In phase 2, adult individuals were identified as the target of the intervention, both as potential “patients” and witnesses of stroke. The low educational level found in the patient survey called for a narrative approach in cartoon form. The family setting was chosen for the message because 42% of patients who presented within 2 hours had been advised by a family member to call EMS. To act on people’s tendency to view stroke as an untreatable disease, it was decided to avoid fear-arousal appeals and use a positive message providing instructions and hope. Focus groups were used to test educational products and identify the most suitable sites for message dissemination.

Conclusions

The IM approach allowed to develop a stroke campaign integrating theories, scientific evidence and information collected from the target population, and enabled to provide clear explanations for the reasons behind key decisions during the intervention development process.

Vectorized nanodelivery systems for ischemic stroke: a concept and a need

Neurological diseases of diverse aetiologies have significant effects on the quality of life of patients. The limited self-repairing capacity of the brain is considered to be the origin of the irreversible and progressive nature of many neurological diseases. Therefore, neuroprotection is an important goal shared by many clinical neurologists and neuroscientists. In this review, we discuss the main obstacles that have prevented the implementation of experimental neuroprotective strategies in humans and propose alternative avenues for the use of neuroprotection as a feasible therapeutic approach. Special attention is devoted to nanotechnology, which is a new approach for developing highly specific and localized biomedical solutions for the study of the multiple mechanisms involved in stroke. Nanotechnology is contributing to personalized neuroprotection by allowing us to identify mechanisms, determine optimal therapeutic windows, and protect patients from brain damage. In summary, multiple aspects of these new players in biomedicine should be considered in future in vivo and in vitro studies with the aim of improving their applicability to clinical studies.

Acute management of stroke in Iran: Obstacles and solutions

Background: Stroke is among the leading causes of mortality and permanent disability in the world. Iran is located in the stroke belt and has a high age-adjusted stroke incidence rate. In this multistep prospective qualitative study, we aimed at investigating the status and challenges of stroke management in Iran and explore possible solutions. Methods: In the first and second phase, we attempted to define the status of stroke management in Iran by searching the relevant literature and conducting semi-structured interviews with health-care providers in thirteen hospitals located in seven large cities in Iran. In the third phase, we tried to recommend possible solutions based on international standards and experience, as well as interviews with stroke experts in Iran and the United States. Results: Little public awareness of stroke symptoms and its urgency, low prioritization for stroke management, and an inadequate number of stroke-ready hospitals are some of the major obstacles toward timely treatment of stroke in Iran. Every hospital in our pool except two hospitals had guideline-based algorithms for the administration of intravenous thrombolysis. However, there was no single call activation system for stroke alert. Data from some of the centers showed that hospital arrival of stroke patients to final decision-making took 116-160 minutes. Although there were four endovascular programs in our target areas, there was no center with 24-hour coverage. Conclusion: There are many challenges as well as potentials for improvement of stroke care in Iran. Improving public knowledge of stroke and establishing an organized and comprehensive stroke program in the hospitals will improve acute stroke management in Iran. The Iranian ministry of health should define and advocate the establishment of stroke centers, track the rate of death and disability from stroke, introduce pathways to improve the quality of stroke care through national data monitoring systems, and eliminate disparities in stroke care.

Acute stroke alert activation, emergency service use, and reperfusion therapy in Sweden

OBJECTIVES

Ambulance services and stroke alerts reduce the time from stroke onset to acute stroke diagnosis. We describe the use of stroke alerts and ambulance services in different hospitals and patient groups and their relationship with reperfusion therapy.

METHODS

This nationwide study included 49,907 patients admitted with acute stroke who were registered in The Swedish Stroke Register (Riksstroke) in 2011-2012.

RESULTS

The proportions of patients admitted as stroke alerts out of all acute stroke admissions varied from 12.2% to 45.7% in university hospitals (n = 9), 0.5% to 38.7% in specialized nonuniversity hospitals (n = 22), and 4.2% to 40.3% in community hospitals (n = 41). Younger age, atrial fibrillation (AF), living in an institution, reduced consciousness upon admission, and hemorrhagic stroke were factors associated with a higher probability of stroke alerts. Living alone, primary school education, non-European origin, previous stroke, diabetes, smoking, and dependency in activities of daily living (ADL) were associated with a lower probability of stroke alert. The proportion of patients arriving at the hospital by ambulance varied from 60.3% to 94.5%. Older age, living alone, primary school education, being born in a European country, previous stroke, AF, dependency in ADL, living in an institution, reduced consciousness upon admission, and hemorrhagic stroke were associated with ambulance services. Hospital stroke alert frequencies correlated strongly with reperfusion rates (r = .75).

CONCLUSION

Acute stroke alerts have a significant potential to improve stroke reperfusion rates. Prehospital stroke management varies conspicuously between hospitals and patient groups, and the elderly and patients living alone have a markedly reduced likelihood of stroke alerts.

Interventions to reduce emergency department utilisation: A review of reviews

OBJECTIVE

To describe policy interventions that have the objective to reduce ED use and to estimate their effectiveness.

METHODS

Narrative review by searching three electronic databases for scientific literature review papers published between 2010 and October 2015. The quality of the included studies was assessed with AMSTAR, and a narrative synthesis of the retrieved papers was applied.

RESULTS

Twenty-three included publications described six types of interventions: (1) cost sharing; (2) strengthening primary care; (3) pre-hospital diversion (including telephone triage); (4) coordination; (5) education and self-management support; (6) barriers to access emergency departments. The high number of interventions, the divergent methods used to measure outcomes and the different populations complicate their evaluation. Although approximately two-thirds of the primary studies showed reductions in ED use for most interventions the evidence showed contradictory results.

CONCLUSION

Despite numerous publications, evidence about the effectiveness of interventions that aim to reduce ED use remains insufficient. Studies on more homogeneous patient groups with a clearly described intervention and control group are needed to determine for which specific target group what type of intervention is most successful and how the intervention should be designed. The effective use of ED services in general is a complex and multi-factorial problem that requires integrated interventions that will have to be adapted to the specific context of a country with a feedback system to monitor its (un-)intended consequences. Yet, the co-location of GP posts and emergency departments seems together with the introduction of telephone triage systems the preferred interventions to reduce inappropriate ED visits while case-management might reduce the number of ED attendances by frequent ED users.

Pre and intrahospital workflow for acute stroke treatment

PURPOSE OF REVIEW

With the recent demonstration of the effectiveness of rapid recanalization of large vessel occlusions in acute ischemic stroke, it is important to assess the current status of pre and intrahospital workflow for acute stroke.

RECENT FINDINGS

We will review trends in the evaluation and treatment of acute stroke and offer suggestions for how best to advance the workflow for acute stroke care in the coming years.

SUMMARY

Future research is needed for: field use of clinical scores for predicting large vessel occlusions, telemedicine to facilitate prehospital triage, and pre and intrahospital processes for optimizing stroke care delivery.

Stroke Ready Intervention: Community Engagement to Decrease Prehospital Delay

BACKGROUND

Time-limited acute stroke treatments are underused, primarily due to prehospital delay. One approach to decreasing prehospital delay is to increase stroke preparedness, the ability to recognize stroke, and the intention to immediately call emergency medical services, through community engagement with high-risk communities.

METHODS AND RESULTS

Our community-academic partnership developed and tested "Stroke Ready," a peer-led, workshop-based, health behavior intervention to increase stroke preparedness among African American youth and adults in Flint, Michigan. Outcomes were measured with a series of 9 stroke and nonstroke 1-minute video vignettes; after each video, participants selected their intended response (primary outcome) and symptom recognition (secondary outcome), receiving 1 point for each appropriate stroke response and recognition. We assessed differences between baseline and posttest appropriate stroke response, which was defined as intent to call 911 for stroke vignettes and not calling 911 for nonstroke, nonemergent vignettes and recognition of stroke. Outcomes assessments were performed before workshop 1 (baseline), at the conclusion of workshop 2 (immediate post-test), and 1 month later (delayed post-test). A total of 101 participants completed the baseline assessment (73 adults and 28 youths), 64 completed the immediate post-test, and 68 the delayed post-test. All participants were African American. The median age of adults was 56 (interquartile range 35-65) and of youth was 14 (interquartile range 11-16), 65% of adults were women, and 50% of youths were women. Compared to baseline, appropriate stroke response was improved in the immediate post-test (4.4 versus 5.2, P<0.01) and was sustained in the delayed post-test (4.4 versus 5.2, P<0.01). Stroke recognition did not change in the immediate post-test (5.9 versus 6.0, P=0.34), but increased in the delayed post-test (5.9 versus 6.2, P=0.04).

CONCLUSIONS

Stroke Ready increased stroke preparedness, a necessary step toward increasing acute stroke treatment rates.

Patient behaviour at the time of stroke onset: a cross-sectional survey of patient response to stroke symptoms

BACKGROUND AND PURPOSE

Revascularisation treatment with thrombolysis must be initiated within 4.5 h following ischaemic stroke symptom onset. Despite its proven benefits, thrombolysis therapy is underused, with patient delay in presenting to hospital with symptoms identified as the leading barrier. This study aimed to examine help-seeking behaviour at stroke onset, in order to understand delays in accessing acute medical care for stroke symptoms.

METHODS

149 consecutive patients hospitalised with ischaemic stroke were interviewed at 72 h poststroke with the Stroke Awareness Questionnaire and the Response to Symptoms Questionnaire.

RESULTS

Sixty per cent of stroke cases presented to the ED within 3.5 h of stroke onset. Knowledge of stroke symptoms and risk factors was poor, with 40% unable to correctly define a stroke. Bystander recognition of symptoms (p=0.03) and bystander initiation of Emergency Medical Services was associated with ED presentation within 3.5 h (p=0.03).

CONCLUSIONS

This study provides insights into patient response when a stroke occurs, with the presence and action of others highlighted as critical in fast response to stroke symptoms. Knowledge of stroke warning signs and risk factors was low among stroke survivors. Findings highlight the complexity of changing help-seeking behaviour during stroke onset, and provide directions for public education efforts to reduce prehospital delay.

Hip Hop Stroke: Study Protocol for a Randomized Controlled Trial to Address Stroke Literacy

Objective

Stroke is the fifth leading cause of death and the leading cause of serious long-term adult disability in the US. Acute stroke treatments with intravenous thrombolysis and endovascular therapy are proven to reduce disability, however a critical limitation on their effectiveness is the narrow time window for administration, which is 4.5 hours and 6 hours respectively from the onset of symptoms. Our overarching goal is to reduce pre-hospital delays to acute stroke treatments in economically disadvantaged minority communities where the greatest delays exist, using Hip Hop Stroke.

Methods

Hip Hop Stroke (HHS) is a school-based, child-mediated, culturally-tailored stroke communication multimedia intervention developed using validated models of behavior change and designed to improve stroke literacy (knowledge of stroke symptoms, the urgent need to call 911, and prevention measures) of 4^th, 5^th and 6^th grade students and their parents residing in poor urban communities. Children in the intervention arm will receive the HHS intervention, while those in the attentional control arm will receive standardized nutrition education based on the USDA's MyPyramid program. Children will be trained and motivated to share stroke information with their parents or other adult caregiver. Both children and parents will complete a stroke knowledge assessment at baseline, immediately following the program, and at 3-months post-program. The primary outcome is the effect of the child mediation on parental stroke literacy.

Conclusion

Stroke literate children, a captive audience in school systems, may represent a viable channel for spreading stroke information into households of poor urban communities where mass media stroke campaigns have shown the lowest penetration. These children may also call 911 when witnessing a stroke in their homes or communities. The HHS program may highlight the potential role of children in the chain of stroke recovery as a strategy for reducing prehospital delays to acute stroke treatment.
