Mechanical Thrombectomy Access Score: A Systematic Review and Modified Delphi of Global Barriers to Endovascular Therapy.

The availability of mechanical thrombectomy (MT) for acute ischemic stroke is limited, and vast disparities exist between countries. We aim to create a MT access score to measure the drivers of access to help quantify and accelerate treatment worldwide. We used a systematic review complemented by a modified Delphi method. In the first of 3 rounds, 4 independent investigators performed a systematic literature review using key search terms that drive MT access, following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. In the second round, a panel of 6 anonymous international experts selected key attributes needed for scoring. In the final round, a total of 12 attributes were selected on consensus, each given a score on a 0 to 3 scale. An ultimate MT access score (range, 0-36) was proposed as a new tool to use in identifying barriers to MT access and assist in providing an initial framework for public health interventions. Of 2864 abstracts screened, 121 studies were included in the final systematic review. A total of 34 attributes that potentially drive MT access were initially identified. In the final round, 12 attributes were selected by the expert panel: public awareness, emergency medical services transportation, prehospital large vessel occlusion screening, interhospital transfer policy, emergency department protocols, stroke imaging protocols, emergency department stroke expertise or telestroke availability, interventionalists, MT-capable centers, device availability, and insurance coverage. These attributes were weighted as part of the final score of 0 to 36. The MT access score represents the first tool to quantify barriers to global MT access. Its implementation stands not just as an academic achievement but as a beacon of hope for improving stroke care and outcomes worldwide, bringing us a step closer to bridging the gap in stroke treatment disparities.

A data envelopment analysis model for optimizing transfer time of ischemic stroke patients under endovascular thrombectomy

This study applies Data Envelopment Analysis (DEA) to optimize transfer times and futile transfers of eligible ischemic stroke patients receiving Endovascular Thrombosis (EVT) in Primary Stroke Centers (PSC) in Nova Scotia. The study aims to assess healthcare delivery in Nova Scotia over two periods. It seeks to improve stroke care for rural populations by examining nine inputs, including age and distance between PSCs and the Comprehensive Stroke Centre (CSC) that provided EVT treatment, concerning a single output variable: whether EVT is performed or not. In the first phase, 115 patients were treated as Decision-Making Units (DMUs) for ten PSCs by applying an input-oriented Variable Returns to Scale (VRS) assisted by super-efficiency analysis using the Python-based PyDEA tool. This tool is known for its unrestricted capacity to handle DMUs, inputs, and outputs. In the second phase, eight PSCs with low patient numbers were merged into four DMUs, each consisting of two PSCs. These two merged PSCs have limited patients, and the selected PSCs are also geographically close. Two PSCs have been kept separate because they had sufficient patient volume. In the first phase, VRS generated more reasonable efficiency scores for evaluation, while in the second phase, Constant Returns to Scale (CRS) outperformed VRS, yielding better results. In the initial stage of the second phase, ten PSCs were considered as six DMUs using the input-oriented CRS and VRS for 115 patients. Super-efficiency measures were applied in this stage to improve the evaluation process further. In the second part of the second phase, a comparison between the first period (2018–2019) and the second period (2020–2021) was conducted using the Malmquist Productivity Index (MPI), considering CRS and VRS to evaluate the relative efficiency and productivity change of six DMUs over time.

Effectiveness of the Stroke e-Learning Module on Malaysian Doctors' Knowledge of Acute Ischaemic Stroke Management.

The Stroke e-Learning Module (SEM) is a nationwide initiative to improve stroke care in Malaysia. This study aimed to assess the module's effectiveness in improving knowledge on acute ischaemic stroke (AIS) management among Malaysian doctors. This was a pre-post study design. Medical officers, specialists and general practitioners from various disciplines who work in healthcare facilities in Malaysia were recruited virtually from those who registered for the SEM on the Docquity platform between 1 February 2021 and 31 January 2022. The Acute Stroke Management Questionnaire (ASMaQ), an existing validated questionnaire, was used to measure the doctors' knowledge of AIS management before and after the SEM. The ASMaQ had three domains: i) general stroke knowledge (GSK), ii) hyperacute stroke management (HSM) and iii) advanced stroke management (ASM). The paired t- and the McNemar-tests were used to evaluate the effectiveness of the module. One hundred and seventy-one participants voluntarily responded to the pre- and post-module questionnaires. The paired t-test revealed statistically significant improvement for the ASM knowledge scores (mean difference = 2.5; 95% CI: 1.8, 3.2; P < 0.001). The baseline proportion of participants with good knowledge of GSK, HSM and ASM were 92.4%, 64.9%, and 76%, respectively. The McNemar test showed that approximately 14% of the participants had significant improvement in ASM knowledge (P < 0.001). However, no significant changes were noted for GSK (-0.6%) and HSM (4.1%). The SEM has been shown to increase Malaysian doctors' knowledge on ASM. However, greater effort should be made to improve GSK and HSM knowledge, particularly in areas related to stroke thrombolysis.

Global Insights on Prehospital Stroke Care: A Comprehensive Review of Challenges and Solutions in Low- and Middle-Income Countries.

Stroke is a leading cause of disability and mortality worldwide, and it disproportionately affects low- and middle-income countries (LMICs), which account for 88% of stroke fatalities. Prehospital stroke care delays are a crucial obstacle to successful treatment in these settings, especially given the limited therapeutic window for thrombolytic treatments, which may greatly improve recovery chances when initiated early after stroke onset. These delays are caused by a lack of public understanding of stroke symptoms, sociodemographic and cultural variables, and insufficient healthcare infrastructure. This review discusses these issues in detail, emphasizing the disparities in stroke awareness and reaction times between locations and socioeconomic classes. Innovative options for reducing these delays include the deployment of mobile stroke units and community-based educational campaigns. This review also discusses how technology improvements and personalized educational initiatives might improve stroke awareness and response in LMICs. The primary goal is to give a thorough assessment of the challenges and potential remedies that might serve as the foundation for policy reforms and healthcare improvements in LMICs, eventually improving stroke care and lowering disease-related mortality and disability.

Prehospital neurologic assessment using mobile phones: Comparison between neurologists and emergency physicians

BackgroundAmbulance-based telestroke may be a promising solution to improving stroke care. We assessed the technical feasibility and reliability of prehospital evaluations using commercial mobile phones with fifth-generation wireless communication technology. MethodsSix standardized patients portrayed scripted stroke scenarios during ambulance transport in an urban city and were remotely evaluated by independent raters using tablets (three neurologists and three emergency physicians) in a hospital, assisted by paramedics (trained in National Institute of Health Stroke Scale [NIHSS] assessment) in the ambulance; commercial cellular networks were utilized for videoconferencing transmission. The primary outcomes were mean difference (MD) and correlation of NIHSS scores between the face-to-face and remote assessments. We also examined the Bland-Altman plot for itemized NIHSS components, and Kaplan–Meier curves were used to compare the differences in the duration of the two evaluations between neurologists and emergency physicians. ResultsWe conducted 32 ambulance runs and successfully completed all NIHSS examinations. No significant difference was found between the face-to-face and remote evaluations (MD, 0.782; 95% confidence interval [CI], −0.520–0.395). The correlation of NIHSS scores between the two methods was 0.994 (95% CI, 0.945–1.026), and three items exhibited the highest frequency of runs, with score differences between the two methods. There were no significant differences between neurologists and emergency physicians in the mean evaluation duration and NIHSS scores for the two methods. ConclusionPrehospital evaluation using commercial mobile phones with fifth-generation wireless communication technology is feasible and reliable during ambulance transport in urban areas. Emergency physicians and neurologists performed similarly in stroke evaluations.

Stroke care in sub-Saharan Africa: Evaluating the present landscape and proposing strategies for improving outcomes

The burden of stroke is alarmingly high in sub-Saharan Africa (SSA), characterized by increasing trends in stroke incidence, prevalence, and mortality. This review details the landscape of stroke care in SSA, encompassing epidemiology, risk factors, care availability, and challenges in advancing stroke care, along with a proposed strategic framework for improvement. Epidemiological studies in SSA indicate a rising trend in stroke incidence and prevalence, with significant variability attributable to differences in study methodologies. Crude incidence rates have risen from an average of 53 (range: 26 &amp;ndash; 101) cases/100,000 population between 1973 and 1991 to 88 (range: 25 &amp;ndash; 149) cases/100,000 population between 2003 and 2011. Similarly, prevalence rates have shown an upward trend. Stroke mortality in SSA remains high, with variability across studies. Key predictors of mortality include hemorrhagic stroke, gender, National Institute of Stroke Scale score at presentation, and comorbidities such as anemia and human immunodeficiency virus infection. However, the interpretation of mortality rates warrants caution due to methodological limitations. Both modifiable and non-modifiable risk factors significantly contribute to stroke risk in SSA. Notably, stroke occurs at a younger age in SSA compared to Western countries. Hypertension, diabetes, dyslipidemia, and lifestyle factors are among the major modifiable risk factors. The availability of organized stroke care varies significantly across SSA, with more advanced care typically found in higher-level health-care centers. However, efforts to improve access and quality of care are ongoing. The challenges in advancing stroke care in SSA include cultural beliefs, limited access to care, and prohibitive costs. A &amp;ldquo;5 Ps&amp;rdquo; framework involving collaboration among policymakers, payers, partners in health care, providers, and patients is proposed to improve stroke care. This review underscores the urgent need for enhanced public health strategies, medical interventions, and collaborative efforts to address the escalating stroke burden in SSA.

Trends in the Use of Medications for Secondary Ischemic Stroke Prevention in Denmark, 2005-2021.

Understanding trends in the use of medications for secondary stroke prevention is crucial for identifying areas for improvement in stroke care. We examined the use of lipid-lowering, antihypertensive, glucose-lowering, oral anticoagulant, and antiplatelet medications after ischemic stroke hospitalization, from 2005 to 2021. Using nationwide registries in Denmark, we identified a cohort of patients discharged from hospital with a first-time or recurrent ischemic stroke (N = 150,744). Stratified by calendar year, we ascertained the 180-day probability of filling a prescription for the abovementioned medications after discharge. We further assessed factors associated with medication use. From 2005 to 2021, lipid-lowering medication use increased from 58.3% to 82.0%; atorvastatin use rose from 2.1% to 64.8% and simvastatin use decreased from 55.7% to 8.6%. Antihypertensive medication use remained stable, at approximately 89%, and various antihypertensive classes were used comparably. Glucose-lowering medication use increased from 71.5% in 2005 to 84.1% in 2021, driven primarily by an increase in metformin use (from 28.0% to 59.5%). Use of glucagon-like peptide-1 receptor agonists and sodium-glucose cotransporter-2 inhibitors continually increased (from 1.7% to 17.5% and from 0.5% to 17.3%, respectively) between 2015 and 2021. Anticoagulant medication use rose from 45.9% in 2005 to 87.0% in 2021, primarily because of increased use of direct oral anticoagulant medications starting around 2010 and a decline in warfarin use. Antiplatelet use remained consistently high, at approximately 95%. Trends were consistent across subgroups of interest; however, overall medication use was lower in older patients (65 years and older), patients with severe stroke, and patients with neurologic and psychiatric comorbidities. Despite increasing trends in the use of 3 of 5 medication classes, the overall use of lipid-lowering, glucose-lowering, and oral anticoagulant medications was somewhat lower than expected according to clinical guidelines, particularly among older patients with more severe stroke and other comorbidities. The relatively low use in these subgroups may signify appropriate clinical decision making in consideration of frequent contraindications and reduced life expectancy or highlight potential areas of improvement for the care of patients with recent ischemic stroke.

Developing Systems of Care for Stroke in Resource-limited Settings.

Although stroke prevention and treatment strategies have significantly advanced in recent years, implementation of these care elements in resource-limited settings can be challenging, since the burden of stroke is higher and access to stroke care is lower. Barriers to stroke care in resource-limited settings include insufficient prevention, reduced awareness of stroke symptoms, limited prehospital care and lack of triage systems, limited access to comprehensive stroke centers, inadequate personnel education, lack of staff and resources, as well as limited access to neuroimaging, thrombolytics, mechanical thrombectomy, neurosurgical care, and rehabilitation. Here, we suggest strategies to improve stroke care in these settings, including public health campaigns, protocols for prehospital notification, organized flow to specialized stroke centers, development of dedicated stroke units, and utilization of telemedicine and telerehabilitation. We also highlight the role of international organizations and governments in reducing the global burden of stroke.

Emerging therapies in the management of acute ischemic stroke: Innovative approaches and clinical outcomes- A comprehensive literature review

Worldwide, acute ischemic stroke continues to be the primary cause of death and disability, requiring ongoing improvements in treatment approaches. With an emphasis on current advancements in collateral evaluation, thrombolytic therapy, endovascular thrombectomy, and neuroprotective treatment, this review examines novel treatments for acute ischemic stroke. To find relevant research published in the past five years, a thorough search of academic databases was carried out. The inclusion criteria for the inclusion of articles on innovative therapeutics and their implications for managing acute stroke were methodological rigor and direct relevance. With an emphasis on the effectiveness and safety of Tenecteplase, the review emphasizes the crucial role that collateral circulation plays in forecasting patient response to reperfusion treatments and the changing landscape of thrombolytic drugs. Furthermore, the treatment of acute strokes has been transformed by developments in endovascular thrombectomy, which provides better functional results for patients with major artery occlusions. Additionally, neuroprotective drugs have potential as complementary treatments, especially when used in combination with reperfusion procedures. Novel treatments for acute ischemic stroke provide fresh chances to improve patient outcomes and lower stroke-related morbidity and death. To provide equal access to improved stroke care, solve outstanding difficulties, and enhance treatment regimens, further research is required.

Overcoming barriers in the implementation of stroke care rehabilitation in a public hospital in Costa Rica

Stroke is a major public health concern in developing countries, where the burden of the disease is high and resources for care are often limited. While progress has been made in improving stroke care, many barriers still exist in providing adequate rehabilitation care for stroke survivors. In this paper we study the case of Costa Rica and how stroke care has been addressed in recent years. It is important to consider the particularities of Costa Rica when working on stroke rehabilitation. The existence of a socialized healthcare system, along with the consolidation of acute stroke management protocols, allows for the adequate management of the early stages. In addition to this, families play a key role in rehabilitation, particularly for a country where there is a lack of medium stay and long-stay rehabilitation centers. Therefore, providing training and education for families is essential in stroke case management. Looking toward the future, there is still a pending need to generate homogeneous stroke rehabilitation protocols throughout the national healthcare system, to ensure equitable access to health care, and to consolidate multidisciplinary groups. At the same time, the implementation of technologies is urgent, particularly considering their potential to help reduce waiting lists. Another goal is enhancing coordination with other state entities and NGOs to advance community, labor or educational reintegration of stroke patients.

Clinical characteristics, Risk factors, and outcomes of Posterior circulation stroke: A retrospective study between younger and older adults in Saudi Arabia

IntroductionPosterior circulation stroke (PCS) may be less prevalent than its anterior counterpart but contributes to substantial morbidity and mortality. The aim was to characterize PCS's demographics, clinical presentation, management, and outcomes between younger and older adults in Saudi Arabia. MethodsThis retrospective cohort study was conducted at two tertiary medical centers in Saudi Arabia between March 2016 and December 2020. All patients who presented with symptoms of posterior circulation stroke and had positive brain imaging were included. ResultsThe study involved 160 posterior circulation stroke patients, stratified into two age groups: 71 patients aged 18-59 years and 89 patients aged 60 years and above. The mean age of the entire cohort was 60.9 years, and 77 % were males. Hypertension was more prevalent in the older age group (88 % vs. 69 %, p=0.005), and smoking was significantly higher among younger patients (38 % vs. 15 %; p=0.0009). Only 22.4 % received thrombolysis and/or thrombectomy. Most strokes involved the posterior cerebral artery (45.6 %). Large artery atherosclerosis was the most common subtype. At discharge, younger patients had higher NIHSS compared to older patients. ConclusionOur investigation of 160 PCS patients in Saudi Arabia uncovers notable trends: a mere 22.4 % received thrombolysis and/or thrombectomy and a significant prevalence of posterior cerebral artery involvement due to large artery atherosclerosis. The study further reveals younger patients disproportionately had severe outcomes. Highlighting the need for improved stroke care and heightened awareness, this research contributes vital data to an underexplored domain, urging further study to optimize care and understand PCS dynamics in Saudi Arabia.

A comparison of in-hospital stroke and community- onset stroke outcomes after endovascular thrombectomy at a tertiary level hospital in Taiwan

Background: While acute-phase thrombectomy is a recognized treatment for main cerebral artery occlusion, variability exists in outcomes for in-hospital stroke and community-onset stroke patients undergoing endovascular thrombectomy. This study investigates the prognostic differences between in-hospital stroke and community-onset stroke patients in an Asian context, with a focus on the impact of patient transfer processes on treatment outcomes. Methods: Data were collected from in-hospital stroke patients who underwent endovascular thrombectomy in a tertiary medical center between January 2017 and December 2020. Propensity score matching with a ratio of 1:4 was performed to compare in-hospital stroke and community-onset stroke patients based on sex, age, NIHSS, and occluded vessel location. Results: The study included 20 in-hospital stroke and 80 community-onset stroke patients, with no significant difference in successful recanalization rates, complications, mortality rates, and NIHSS and mRS scores between the groups. The community-onset stroke group had longer times to treatment, particularly among transferred patients. A high proportion of in-hospital stroke patients had undergone surgery before their stroke, and a greater incidence of heart failure was noted in this group. Conclusion: Despite pre-stroke surgical treatments and a higher rate of heart failure in in-hospital stroke patients, prompt endovascular thrombectomy resulted in comparable outcomes to community- onset stroke patients. The study underscores the importance of reducing treatment times, especially for transferred patients, to improve stroke care efficacy.

A Holistic Approach to Expressing the Burden of Caregivers for Stroke Survivors: A Systematic Review.

This systematic review explores the multifaceted challenges faced by caregivers of stroke survivors, addressing the global impact of strokes and the anticipated rise in survivors over the coming decades. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a thorough literature search identified 34 relevant studies published between 2018 and 2023. The review categorizes caregiver burden into four domains: physical health, social functioning, financial issues, and psychological health. Caregivers often experience a decline in physical health, marked by chronic fatigue, sleep disturbances, and pain. Emotional distress is prevalent, leading to anxiety and depression, especially in cases of high burden. Financial strains arise from medical expenses and employment changes, exacerbating the overall burden. Contextual factors, such as cultural norms and resource availability, influence the caregiver experience. The Newcastle-Ottawa scale assessed the methodological quality of studies. The conclusion emphasizes tailored interventions and support systems for caregivers, with practical recommendations for healthcare professionals, therapists, mental health professionals, financial counselors, and policymakers. This comprehensive review enhances the understanding of caregiver experiences and provides actionable insights to improve stroke care and rehabilitation The study's novelty lies in its holistic examination of caregiver burden in stroke care, its focus on the recent literature, and its emphasis on forecasting caregiver outcomes, contributing valuable insights for proactive intervention strategies.

This study aims to evaluate the prevalence of risk factors and stroke awareness among university students.&#x0D; Methods:&#x0D; This cross-sectional study was conducted among students at Sardar Bahadur Khan Women's University in Quetta. An eleven-question multiple-choice survey was administered to assess participants' knowledge of stroke-related concepts. The initial study was conducted using descriptive statistics. Additionally, a supplementary screening for common risk factors linked to stroke was included in the study, which involved blood pressure, blood sugar, and cholesterol measures. Data were coded, entered into SPSS, and screened for missing values and outliers. Descriptive analyses were conducted, including frequency tables and graphical representations using pie charts.&#x0D; Results:&#x0D; In our survey of 255 female students, the vast majority (94.9%) correctly classified stroke as a brain disease, whereas a lesser percentage (1.6%) confused it with heart (0.8%), kidney (0.8%), or lung diseases (0.8%) problems. Notably, 74.1% of participants were aware of the precise cause of stroke, but 58.8% identified arm and leg weakness as a symptom. Other symptoms that were recognized by participants included difficulties speaking (25.5%), headache (9.8%), vertigo (2.4%), and chest pain (3.4%). Moreover, 94.9% of participants recognized that stroke is preventable. The most often diagnosed risk factor was hypertension (58.4%), which was followed by high cholesterol (11.8%), diabetes (9.0%), migraine (8.2%), advanced age (7.8%), and smoking (4.7%).&#x0D; Conclusion&#x0D; Our study shows a very good knowledge about stroke among the students at Sardar Bahadur Khan University but our results are biased due to addressing only an educated group of people.

Accreditation of stroke programs at the MENA + region; between aspiration and reality

IntroductionDespite global progress in stroke care, challenges persist, especially in Low- and Middle-Income countries (LMIC). The Middle East and North Africa Stroke and Interventional Neurotherapies Organization (MENA-SINO) Stroke Program Accreditation Initiative aims to improve stroke care regionally. Material & methodA 2022 survey assessed stroke unit readiness in the Middle East and North Africa (MENA) + region, revealing significant regional disparities in stroke care between high-income and low-income countries. Additionally, it demonstrated interest in the accreditation procedure and suggested that regional stroke program accreditation will improve stroke care for the involved centers. ConclusionAn accreditation program that is specifically tailored to the regional needs in the MENA + countries might be the solution. In this brief review, we will discuss potential challenges faced by such a program and we will put forward a well-defined 5-step accreditation process, beginning with a letter of intent, through processing the request and appointment of reviewers, the actual audit, the certification decisions, and culminating in granting a MIENA-SINO tier-specific certificate with recertification every 5 years.

Abstract WMP38: Access to Acute Stroke Care: Global Perspective From Registry of Stroke Care Quality (RES-Q)

Introduction: Disparities in access to acute stroke care represents a major global challenge. Addressing such challenges requires a comprehensive understanding of the variations in stroke care quality between nations. Methods: We used data from the global Registry of Stroke Care Quality (RES-Q). RES-Q is web-based quality monitoring platform for the management of stroke care. Key quality metrics on patients with acute ischemic stroke admitted in 2022 were calculated: patients percentage arriving by Emergency Medical Services (EMS); patients percentage admitted to the Stroke Unit/Intensive Care Unit (ICU); Door-to-Imaging Time (DIT), Door-to-Needle Time (DNT) for intravenous thrombolysis. Results: Of 153 181 patients across 912 hospitals in 67 countries enrolled in the register, 125 390 had acute ischemic stroke. After excluding secondary transfers (n=26 648), missing or erroneous data (n=45 526), and countries with &lt;200 cases (n=1 410), a total of 51,806 patients from 696 hospitals and in 30 countries were analyzed. The percentage of patients arriving at healthcare facilities by EMS varied from 3% to 98% (median 51%; IQR 26-87) and admitted to the Stroke Units/ICUs from 25% to 99% (median 78%; IQR 47-89). The median DIT was 32; IQR 21-39, with range 10-60 minutes. The median DNT was 44; IQR 31-52, with range 20-71 minutes. Median DNT of patients admitted directly to the CT scanner was 24 minutes (IQR 15-38), and, if admitted to the emergency department, DNT was 39 minutes (IQR 25-55). Data by quartiles (best is blue, worst is red) from each country are presented in a detailed Table below. Conclusion: Our study underscores the critical role of the global registry in enabling cross-national comparative analyses of acute stroke care quality. The findings highlight disparities and variations in critical aspects of acute stroke care, paving the way for targeted interventions, policy reforms, and enhanced collaboration among stakeholders to improve stroke care globally.

Abstract TMP20: Mapping the Expansion of the Minnesota Stroke System of Care

Objectives: Stroke is the fifth leading cause of death in Minnesota (MN) and in the United States. The state of MN a has a unique geographical layout with many healthcare facilities located in rural areas. In 2013 legislation was passed authorizing the Minnesota Department of Health to designate hospitals as Acute Stroke Ready Hospitals, Primary Stroke Centers, and Comprehensive Stroke Centers. When a hospital joins the MN Stroke System they maintain vital infrastructure, expertise, and care processes to provide high quality stroke care in accordance with evidence-based guidelines. We used geographic information systems (GIS) methods to visualize the growth and expansion of the Minnesota Stroke System and quantify its reach to Minnesotans across the state over a 10-year period. Methods: Using the Network Analyst extension of ESRI ArcGIS Desktop 10.8.2, 30- and 60- minute drive time service areas were calculated around each designated hospital in 2013, 2017 and 2023. Census block groups were identified where the mean center of population fell within the 30-minute drive time areas and the populations of those block groups were summed. A percentage was calculated using the total Minnesota population as the denominator. Results: In 2013, only 66% of Minnesota’s population lived within 30 minutes of a designated stroke center and 80% lived within a 60-minute drive time. Stroke designated hospitals (19) were largely concentrated in metropolitan areas, leaving many rural Minnesotans without ready access to stroke centers. After the first cycle in 2017, or three-year period post statute, drive time status increased to 90% of the population living within 30 minutes of a designated stroke system hospital and 98% living within a 60- minute drive time. As of 2023, 94% of Minnesotans now live within a 30-minute drive of a designated Stroke System Hospital and 99% live within a 60-minute drive time. Conclusions: Stroke statute was the catalyst for improving stroke care access in MN. The voluntary system of care expanded rapidly from 19 initial hospitals to 119 over a 10-year period. This progress means more than 1.9 million additional Minnesotans now have better access to emergency stroke care.

Abstract WP92: Application of a Horizontal Communication Process in Combination With Artificial Intelligence (AI) to Improve Stroke Care in Patients With Large Vessel Occlusion (LVO)

Introduction: Timely acute stroke care in patients with large vessel occlusion (LVO) requires both early detection of LVO and efficient multidisciplinary communication. In this study, we aimed to evaluate the impact of using AI and a horizontal communication system within the RapidAI application platform on acute stroke quality metrics in patients with LVO. Methods: On April 2022, the RapidAI application was launched at our center, which allowed for use of AI as a screening measure for LVO detection with immediate notification to neurology, neuroradiology, and neuro-interventional teams. The various teams used instant messaging within the application to communicate clinical data, imaging findings and shared clinical decision making. In this single center study, we retrospectively evaluated stroke care quality metrics for 167 consecutive patients (mean age: 71.6, 49.1% male) who underwent mechanical thrombectomy (MT) from January 2021 to May 2023. Data were compiled from multiple resources including Get-With-The-Guidelines®, chart abstraction, and internal healthcare databases. The groups were compared using appropriate statistical tests and significance was determined using a two-sided alpha of 0.05. Results: 85 patients underwent MT before implementation of the new system, and 82 patients underwent MT after. Demographic features (age, sex, race), cerebrovascular risk factors (hypertension, diabetes, hyperlipidemia, smoking, BMI) and stroke severity were similar between the two groups (p&gt;0.05). Average door to groin puncture (pre: 97 minutes, post: 82 minutes, p=0.10) and discharge disposition (p=0.02) were significantly different between the two groups. In an adjusted analysis of door to groin puncture time, the difference between pre-RapidAI and post-RapidAI was an average reduction of 19 minutes trending towards significance (p = 0.06). Conclusion: Application of a horizontal communication platform in combination with RapidAI was associated with significant improvements in time to intervention in patients with LVO and a significant improvement in the number of patients discharged home.

Criteria and Indicators for Centers of Clinical Excellence in Stroke Recovery and Rehabilitation: A Global Consensus Facilitated by ISRRA

Background The aim of the International Stroke Recovery and Rehabilitation Alliance is to create a world where worldwide collaboration brings major breakthroughs for the millions of people living with stroke. A key pillar of this work is to define globally relevant criteria for centers that aspire to deliver excellent clinical rehabilitation and generate exceptional outcomes for patients. Objectives This paper presents consensus work conducted with an international group of expert stroke recovery and rehabilitation researchers, clinicians, and people living with stroke to identify and define criteria and measurable indicators for Centers of Clinical Excellence (CoCE) in stroke recovery and rehabilitation. These were intentionally developed to be ambitious and internationally relevant, regardless of a country’s development or income status, to drive global improvement in stroke services. Methods Criteria and specific measurable indicators for CoCE were collaboratively developed by an international panel of stroke recovery and rehabilitation experts from 10 countries and consumer groups from 5 countries. Results The criteria and associated indicators, ranked in order of importance, focused upon (i) optimal outcome, (ii) research culture, (iii) working collaboratively with people living with stroke, (iv) knowledge exchange, (v) leadership, (vi) education, and (vii) advocacy. Work is currently underway to user-test the criteria and indicators in 14 rehabilitation centers in 10 different countries. Conclusions We anticipate that use of the criteria and indicators could support individual organizations to further develop their services and, more widely, provide a mechanism by which clinical excellence can be articulated and shared to generate global improvements in stroke care.
