RESUMEN

BACKGROUND: Endovascular thrombectomy, the preferred treatment for acute large-vessel occlusion stroke, is highly time-dependent. Many patients live far from thrombectomy centers due to large geographical variations in stroke services. This study aimed to explore the consequences of long transport distance on the proportion of thrombectomy-eligible patients who underwent thrombectomy, the clinical outcomes with or without thrombectomy, the timelines for patients transported, and the diagnostic accuracy of large-vessel occlusion in primary stroke centers. METHODS: We conducted a retrospective observational study in a county with only primary stroke centers, ∼ 300 km from the nearest thrombectomy center. All stroke patients admitted over a year were retrieved from the Norwegian Stroke Registry. A neuroradiologist identified all computed tomography images with large-vessel occlusions. A panel determined whether these patients had a corresponding clinical indication for thrombectomy. RESULTS: A total of 50% of the eligible patients did not receive thrombectomy. These patients had a significantly higher risk of severe disability or death compared to the patients who underwent thrombectomy. The median time from computed tomography imaging at the primary stroke center to arrival at the thrombectomy center was over 3 hours. Additionally, 30% of the large-vessel occlusions were initially undiagnosed, and half of these patients had a corresponding clinical indication for thrombectomy. CONCLUSIONS: In a county with a long transport distance to a thrombectomy center, a high proportion of eligible patients did not undergo thrombectomy, negatively impacting clinical outcomes. The transport time was considerable. A high rate of large-vessel occlusions was initially not diagnosed.

RESUMEN

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.

RESUMEN

In the last decade, mobile stroke units (MSUs) have shown the potential to transform prehospital stroke care, marking a paradigm shift in delivering ultra-rapid thrombolysis and streamlining triage processes. These units bring acute stroke care directly to patients, significantly shortening treatment times. This review outlines the rationale for MSU care and discusses the potential applications beyond the original purpose of delivering thrombolysis, including large vessel occlusion detection, intracerebral hemorrhage management, and innovative forms of prehospital research.

RESUMEN

Background and purpose: Mobile stroke units (MSU) have been demonstrated to improve prehospital stroke care in metropolitan and rural regions. Due to geographical, social and structural idiosyncrasies of the German city of Mannheim, concepts of established MSU services are not directly applicable to the Mannheim initiative. The aim of the present analysis was to identify major determinants that need to be considered when initially setting up a local MSU service. Methods: Local stroke statistics from 2015 to 2021 were analyzed and circadian distribution of strokes and local incidence rates were calculated. MSU patient numbers and total program costs were estimated for varying operating modes, daytime coverage models, staffing configurations which included several resource sharing models with the hospital. Additional case-number simulations for expanded catchment areas were performed. Results: Median time of symptom onset of ischemic stroke patients was 1:00 p.m. 54.3% of all stroke patients were admitted during a 10-h time window on weekdays. Assuming that MSU is able to reach 53% of stroke patients, the average expected number of ischemic stroke patients admitted to MSU would be 0.64 in a 10-h shift each day, which could potentially be increased by expanding the MSU catchment area. Total estimated MSU costs amounted to € 815,087 per annum. Teleneurological assessment reduced overall costs by 11.7%. Conclusion: This analysis provides a framework of determinants and considerations to be addressed during the design process of a novel MSU program in order to balance stroke care improvements with the sustainable use of scarce resources.

RESUMEN

INTRODUCTION: Despite 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 & METHOD: A 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. CONCLUSION: An 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.

RESUMEN

OBJECTIVE: To report COVID -19 pandemic impact on mobile stroke units (MSUs) a world-wide survey of MSU programs. METHODS: Contact information of MSU program was obtained through the Pre-hospital Stroke Treatment Organization. Anonymous electronic questionnaire was developed and sent through the email to one representative of each program on May 15, 2020. RESULTS: Of 26 programs queried, 20 responded and completed survey based on the data or personal impression. Eighteen programs were in the regions with pandemic lockdown. Six either suspended or reduced MSU availability at some point. The reasons given for change in availability were as follows: decreased personnel availability (5 programs), risk of exposure (5 programs), and financial concerns (1 program). Staff availability was a concern among 8 programs. MSU activations were reported to be unchanged by 10 programs, but 9 programs experienced decline in activation, 1 program had more activations. Sixteen programs reported change in MSU protocol including introduction of screening questionnaire, PPE, reducing patient contact, and cleaning protocols. Nine reported that the crew was under greater stress. Only 2 respondents felt that the pandemic delayed stroke care on MSU and the remainder did not. CONCLUSION: Overall Stroke care delivery had no major disruptions despite COVID 19 pandemic posed challenges to MSU Operations.

RESUMEN

Introduction: Intravenous thrombolysis (IVT) and mechanical thrombectomy (MT) are well-established, evidence-based, time-critical therapies that reduce morbidity and mortality in acute ischemic stroke (AIS) patients. The exclusion of intracerebral hemorrhage (ICH) is mandatory and has been performed by cerebral imaging to date. Mobile stroke units (MSUs) have been shown to improve functional outcomes by bringing cerebral imaging and IVT directly to the patient, but they have limited coverage. Blood biomarkers clearly distinguishing between AIS, ICH, and stroke mimics (SM) could provide an alternative to cerebral imaging if concentration changes are detectable in the hyperacute phase after stroke with high diagnostic accuracy. In this study, we will take blood samples in a prehospital setting to evaluate potential biomarkers. The study was registered in the German Clinical Trials Register (https://drks.de/search/de) with the identifier DRKS00023063. Methods and analysis: We plan a prospective, observational study involving 300 patients with suspected stroke and symptom onset of ≤4.5 h before the collection of biomarkers. Study participants will be recruited from three sites in Berlin, Germany during MSU deployments. The focus of the study is the collection of blood samples from participants at the prehospital scene and from participants with AIS or ICH at a second-time point. All samples will be analyzed using targeted and untargeted analytical approaches. Study-related information about participants, including medical information and discharge diagnoses from the subsequent treating hospital, will be collected and documented in an electronic case report form (eCRF). Discussion: This study will evaluate whether a single blood biomarker or a combination of biomarkers can distinguish patients with AIS and ICH from patients with stroke and SM in the early phase after symptom onset in the prehospital setting. In addition, the kinetics of blood biomarkers in AIS and ICH patients will be investigated. Our goal is to evaluate new ways to reliably diagnose stroke in the prehospital setting and thus accelerate the application of evidence-based therapies to stroke patients.

RESUMEN

The rate of stroke-related death and disability is four times higher in low- and middle-income countries (LMICs) than in high-income countries (HICs), yet stroke units exist in only 18% of LMICs, compared with 91% of HICs. In order to ensure universal and equitable access to timely, guideline-recommended stroke care, multidisciplinary stroke-ready hospitals with coordinated teams of healthcare professionals and appropriate facilities are essential.Established in 2016, the Angels Initiative is an international, not-for-profit, public-private partnership. It is run in collaboration with the World Stroke Organization, European Stroke Organisation, and regional and national stroke societies in over 50 countries. The Angels Initiative aims to increase the global number of stroke-ready hospitals and to optimize the quality of existing stroke units. It does this through the work of dedicated consultants, who help to standardize care procedures and build coordinated, informed communities of stroke professionals. Angels consultants also establish quality monitoring frameworks using online audit platforms such as the Registry of Stroke Care Quality (RES-Q), which forms the basis of the Angels award system (gold/platinum/diamond) for all stroke-ready hospitals across the world.The Angels Initiative has supported over 1700 hospitals (>1000 in LMICs) that did not previously treat stroke patients to become "stroke ready." Since its inception in 2016, the Angels Initiative has impacted the health outcomes of an estimated 7.46 million stroke patients globally (including an estimated 4.68 million patients in LMICs). The Angels Initiative has increased the number of stroke-ready hospitals in many countries (e.g. in South Africa: 5 stroke-ready hospitals in 2015 vs 185 in 2021), reduced "door to treatment time" (e.g. in Egypt: 50% reduction vs baseline), and increased quality monitoring substantially.The focus of the work of the Angels Initiative has now expanded from the hyperacute phase of stroke treatment to the pre-hospital setting, as well as to the early post-acute setting. A continued and coordinated global effort is needed to achieve the target of the Angels Initiative of >10,000 stroke-ready hospitals by 2030, and >7500 of these in LMICs.

RESUMEN

The rate of neural circuitry loss in a typical large vessel occlusion well emphasizes that 'Time is Brain'. Every untreated minute in a large vessel ischaemic stroke results in loss of 1.9 million neurons and 13.8 billion synapses. As such, it is essential to optimize the flow-limiting steps in delivering the current standard of care. The current diagnostic model involves recognition of symptoms by patients, followed by access to Emergency Medical Services and subsequent physical examination and neuroimaging in the Emergency Department. With more than 50% of stroke patients using Emergency Medical Services as the first point of care contact, it can be deduced that the outcome of the 'stroke chain of survival' can be improved by addressing the bottleneck of prehospital stroke diagnosis. Here we present a review of the existing technologies.

RESUMEN

BACKGROUND: The efficacy of mobile stroke units (MSUs) in improving acute ischemic stroke (AIS) care in developing countries is unknown. We compared performance measures and stroke outcomes in AIS patients between MSU and usual care: emergency medical services (EMS) and walk-in. METHODS: We enrolled patients > 18 years of age with an AIS within 4.5 h after onset. Demographic data, types, and time of reperfusion therapies and clinical outcomes were recorded. A favorable outcome was defined as a modified Rankin Scale (mRS) 0-2 at 3 months. RESULTS: A total of 978 AIS patients (MSU = 243, EMS = 214, walk-in = 521) were enrolled between June 1, 2018, and April 30, 2021. The mean age (± SD) was 66 (± 14) years, and 510 (52.1%) were male. AIS time metrics were the shortest in the MSU with a mean (± SD) door to needle (DN) time of 20 (± 7), 29 (± 13), and 35 (± 16) min (p < 0.001) and door to puncture (DP) time of 73 ± 19, 86 ± 33, and 101 ± 42 min (p < 0.001) in MSU, EMS, and walk-in, respectively. Participants in the MSU (56.8%) received higher rate of reperfusion therapie(s) when compared to the EMS (51.4%) and walk-in (31.5%) (p < 0.001). After adjustment for any potential confounders and using the EMS as a reference, the MSU has the highest likelihood of achieving a favorable outcome (adjusted OR 2.15; 95% CI 1.39-3.32). CONCLUSIONS: In underserved populations, MSUs significantly reduced DN time, increased the likelihood of receiving reperfusion treatment, and achieved independency at 3 months when compared to usual care.

RESUMEN

Introduction: Acute ischemic stroke (AIS) is a time-critical medical emergency. For patients with large-vessel occlusions (LVO), mechanical thrombectomy (MT) is the gold-standard treatment. Mobile Stroke Units (MSUs) provide on-site diagnostic capabilities via computed tomography (CT) and have been shown to improve functional outcomes in stroke patients, but are cost-efficient only in urban areas. Blood biomarkers have recently emerged as possible alternative to cerebral imaging for LVO diagnosis. Prehospital LVO diagnosis offers the potential to transport patients directly to centers that have MT treatment available. In this study, we assess the accuracy of combining two biomarkers, HFABP and NT-proBNP, with clinical indicators to detect LVO using ultra-early prehospital blood samples. The study was registered in the German Clinical Trials Register (DRKS-ID: DRKS00030399). Methods and analysis: We plan a multicenter prospective observational study with 800 patients with suspected stroke enrolled within 24 h of symptom onset. Study participants will be recruited at three sites (MSUs) in Berlin, Germany. Blood-samples will be taken pre-hospitally at the scene and tested for HFABP and NT-proBNP levels. Additional clinical data and information on final diagnosis will be collected and documented in an electronic case report form (eCRF). Sensitivity and specificity of the combination will be calculated through iterative permutation-response calculations. Discussion: This study aims to evaluate the diagnostic capabilities of a combination of the biomarkers HFABP and NT-proBNP in LVO prediction. In contrast to most other biomarker studies to date, by employing MSUs as study centers, ultra-early levels of biomarkers can be analyzed. Point-of-care LVO detection in suspected stroke could lead to faster treatment in both urban and rural settings and thus improve functional outcomes on a broader scale.

RESUMEN

Introducción: el ACV constituye un problema de salud y la trombólisis sistémica una estrategia de reperfusión con alto nivel de evidencia para su tratamiento. Los reportes nacionales sobre su utilización son escasos. Objetivos: comunicar y analizar los resultados de esta terapia en el Hospital de Clínicas. Establecer predictores de buena evolución, hemorragia intracraneana y mortalidad. Métodos: estudio observacional analítico de los pacientes trombolizados en el Hospital de Clínicas (2010-2021). Resultados: se realizó trombólisis sistémica a 268 pacientes. La mediana del NIHSS al ingreso fue 12 puntos. Un 42% fueron infartos totales de la circulación anterior. La cardioembolia constituyó la etiopatogenia más frecuente. El 59,3% de los pacientes fueron externalizados con independencia funcional y 55,2% con déficit neurológico mínimo. Las tasas de hemorragia intracraneana sintomática y mortalidad fueron 7,1% y 18,7% respectivamente. El 57% de los pacientes se trataron con tiempo puerta aguja ≤60 minutos. El porcentaje de trombólisis en el total de ACV fue 18,9%. La edad, NIHSS al ingreso e internación en unidad de ACV se comportaron como variables importantes para predecir buena evolución, hemorragia intracraneana y muerte. Discusión y conclusiones: se comunicó la mayor casuística nacional sobre el tema. Los parámetros de efectividad y seguridad del tratamiento fueron comparables a los reportados internacionalmente. Se destacaron los buenos tiempos puerta aguja y tasa trombólisis sobre ACV totales como indicadores satisfactorios de calidad asistencial.

Introduction: Strokes are a health problem and systemic thrombolysis constitutes a reperfusion strategy backed up by significant evidence on its positive therapeutic impact. National reports on its use are scarce. Objectives: To report and analyze results obtained with this therapeutic approach at the Clinicas Hospital. To establish predictive factors for a good evolution, intracranial hemorrhage and mortality. Method: Observational, analytical study of thrombolysed patients at Clinicas Hospital (2010-2021). Results: Systemic thrombolysis was performed in 268 patients. Average NIHSS score was 12 points when admitted to hospital.42 % of cases were total anterior circulation infarct (TACI). Cardioembolic ischaemmic stroke was the most frequent etiopahogenesis. 59.3% of patients were discharged with functional independence and 55.2% had minimal neurologic deficit. Symptomatic intracranial hemorrhage and mortality rates were 7.1% and 18.7% respectively. 57% of patients were assisted within ≤60 minutes they showed up at the ER. Thrombolysis percentage in total number of strokes was 18.9%. Age, NIHSS score upon arrival to hospital and admission to the stroke unit were significant variables to predict a good evolution, intracranial hemorrhage and death. Discussion and conclusions: The large number of cases in the country was reported. Effectiveness and safety parameters for this treatment were comparable to those reported internationally. The good door-to-needle time and thrombolysis rate versus total number of strokes stood out as satisfactory indicators of healthcare quality. Admission to the stroke unit behaved as a predictive factor of functional independence and it protected patients from hospital mortality.

RESUMEN

Background: Acute stroke care is complex and requires multidisciplinary networking. There are insufficient data on stroke care in the Middle East and adjacent regions in Asia and Africa. Objective: Evaluate the state of readiness of stroke programs in the Middle East North Africa and surrounding regions (MENA+) to treat acute stroke. Method: Online questionnaire survey on the evaluation of stroke care across hospitals of MENA+ region between April 2021 and January 2022. Results: The survey was completed by 34/50 (68%) hospitals. The median population serviced by participating hospitals was 2 million. The median admission of patients with stroke/year was 600 (250-1,100). The median length of stay at the stroke units was 5 days. 34/34 (100%) of these hospitals have 24/7 CT head available. 17/34 (50%) have emergency guidelines for prehospital acute stroke care. Mechanical thrombectomy with/without IVT was available in 24/34 (70.6%). 51% was the median (IQR; 15-75%) of patients treated with IVT within 60 min from arrival. Thirty-five minutes were the median time to reverse warfarin-associated ICH. Conclusion: This is the first large study on the availability of resources for the management of acute stroke in the MENA+ region. We noted the disparity in stroke care between high-income and low-income countries. Concerted efforts are required to improve stroke care in low-income countries. Accreditation of stroke programs in the region will be helpful.

RESUMEN

BACKGROUND: older patients are less frequently treated in stroke units (SUs). Clinicians do not seem convinced that older patients benefit from specialised treatment in SU similarly to younger patients. OBJECTIVE: our study aimed to compare older patients' long-term outcomes with and without SU treatment. METHODS: this study used routinely collected health data of 232,447 patients admitted to hospitals in Germany between 2007 and 2017 who were diagnosed with ischaemic stroke (ICD 10 I63). The sample included 29,885 patients aged ≥90 years. The outcomes analysed were 10-, 30- and 90-day, and 1-, 3- and 5-year mortality and the combinations of death or recurrence, inpatient treatment and increase in long-term care needs. Bivariate chi-square tests and multivariable logistic regression analyses were used, adjusting for the covariates age, sex, co-morbidity, long-term care needs before stroke and socioeconomic status of the patients' region of origin. RESULTS: between 2007 and 2017, 57.1% of patients aged <90 years and 49.6% of those aged ≥90 years were treated in a SU. The 1-year mortality rate of ≥90-year-olds was 56.9 and 61.9% with and without SU treatment, respectively. The multivariable-adjusted risk of death in ≥90-year-olds with SU treatment was odds ratio (OR) = 0.67 (95% confidence interval [CI] = 0.62-0.73) 10 days after the initial event and OR = 0.76 (95% CI = 0.71-0.82) 3 years after stroke. CONCLUSIONS: even very old patients with stroke benefit from SU treatment in the short and long term. Therefore, SU treatment should be the norm even in older patients.

RESUMEN

Introduction: The COVID19 pandemic collapsed intensive care units (ICUs) all around the world, conditioning systems of care (SOC) for other critical conditions such as severe ischemic stroke requiring endovascular treatment (EVT). Our aim was to evaluate the impact of an adaptive Stroke Unit (SU) based SOC on functional outcomes, with the goal of avoiding both general anesthesia (GA) and ICU admission in stroke patients treated with EVT. Material and methods: We performed an observational study comparing data from our traditional ICU-GA based SOC and the adaptive SU-Conscious Sedation (CS) based SOC (consecutive patients undergoing EVT 1 year prior and after onset of the pandemic). Primary outcome was 90-days modified Rankin Scale (mRS), and secondary outcomes included, among others, in-hospital complications, and hospital length of stay (LOS). Results: A total of 210 EVT were performed during the study period (107 under the traditional-SOC and 103 under the adaptive-SOC). A significantly greater proportion of patient was treated under CS (15.9% vs 57.3%; p < 0.001) and admitted for post-procedural care at SU (15% vs 66%; p < 0.001) in the adaptive SOC. Rates of in-hospital complications were similar in both periods, with reduced hospital LOS in the adaptive SOC (10 (7-15) vs 8 (6-12); p = 0.005). The adaptive SOC was associated with higher odds for 90 days favorable outcome (mRS 0-2) (aOR 3.15 (1.34-7.39); p = 0.008). Conclusion: In our case, an adaptive SOC that combined both preference for CS and postprocedural care in SU was associated with better functional outcomes and reduced healthcare resource use for patients undergoing EVT.

RESUMEN

BACKGROUND: Central retinal artery occlusion (CRAO) is a neuro-ophthalmological emergency whose optimal management is still under debate and due to the absence of definite guidelines, practice is expected to vary. We aimed to characterize early evaluation as well as acute treatment and diagnostic approaches in German hospitals with a stroke unit (SU). METHODS: In 07/2021, all 335 certified German SUs were invited to participate in an anonymous online survey endorsed by the German Stroke Society on emergency department care organization, diagnostic procedures, and treatment of patients with unilateral vision loss (UVL) subsequently diagnosed with CRAO. RESULTS: One hundred and sixty-three (48.6%) of the 335 eligible centers responded. Most (117/135; 86.7%) stated that UVL patients were treated as an emergency, in 62/138 (44.9%) hospitals according to specific guidelines. First-line evaluation was performed by neurologists in 85/136 (62.5%) hospitals, by ophthalmologists in 43/136 (31.6%) hospitals. Seventy of 135 (51.9%) respondents indicated a lack of on-site ophthalmological expertise. Seventy-four of 129 (57.4%) respondents performed thrombolysis in CRAO and 92/97 (94.8%) stated that patients with CRAO-if admitted to neurology-were treated on a SU. CONCLUSIONS: Our findings reflect notable heterogeneity in early intrahospital care of CRAO in German SUs but demonstrate a preference for work-up and management as acute stroke by the involved neurologists. Streamlining interdisciplinary emergency evaluation is essential for ongoing and future prospective trials.

RESUMEN

Ischemic stroke accounts for 80% of overall stroke, and is one of the leading causes of death, disability and dementia in worldwide. Management of patients with acute ischemic stroke dramatically improved over time with the implementation of intensive care stroke units, the development of acute recanalization strategies, the optimization of the management of post-stroke complications, and the prevention of early stroke recurrence. The objective of this article is to provide a general overview of the current management of patients with acute ischemic stroke aiming at improving post-stroke outcome.

RESUMEN

BACKGROUND: The patients with ruptured vertebral artery dissecting aneurysm (rVADA) should be treated as early as possible because VADA carries extremely high risk of rebleeding in the acute phase. We have established a mobile endovascular strategy for the patients with rVADA between our flagship center and its affiliated local hospitals. We introduced and reviewed our mobile endovascular therapy in this study. METHODS: We retrospectively evaluated 98 consecutive patients who underwent endovascular surgery for rVADA from 2000 to 2018 at our institution or five affiliated hospitals. When each patient was initially transported to the local affiliated hospitals, neuroendovascular surgeons traveled directly to the affiliated hospital from the flagship center in order to treat the patient there. Clinical outcomes using modified Rankin Scale at 6 months after treatment, radiological results, and procedure-related complications were reviewed to justify our mobile endovascular strategy. RESULTS: All aneurysms were cured successfully by internal trapping. Favorable outcome was achieved in 61 patients (62.2%) even though 53 patients (54.1%) had presented with severe subarachnoid hemorrhage. Overall mortality rate, treatment-related mortality rate, and treatment related complication rate were 18.4% (18/98), 0%, and 16% (16/98), respectively. There were no differences in clinical and radiological outcomes between the patients treated in the flagship center and those who treated in the affiliated hospitals. Treatment in the affiliated hospital was not a predictive factor of unfavorable outcome in our multivariate analysis, and elderly age (≥ 60) was negatively associated with favorable outcome. CONCLUSIONS: Our results prove the efficacy and safety of mobile endovascular therapy for the treatment of rVADA in the ultra-acute stage. Mobile endovascular therapy may work well in the acute treatment of rVADAs in the certain circumstance.

RESUMEN

Introduction: Stroke is one of the leading causes of death in Latin America, a region with countless gaps to be addressed to decrease its burden. In 2018, at the first Latin American Stroke Ministerial Meeting, stroke physician and healthcare manager representatives from 13 countries signed the Declaration of Gramado with the priorities to improve the region, with the commitment to implement all evidence-based strategies for stroke care. The second meeting in March 2020 reviewed the achievements in 2 years and discussed new objectives. This paper will review the 2-year advances and future plans of the Latin American alliance for stroke. Method: In March 2020, a survey based on the Declaration of Gramado items was sent to the neurologists participants of the Stroke Ministerial Meetings. The results were confirmed with representatives of the Ministries of Health and leaders from the countries at the second Latin American Stroke Ministerial Meeting. Results: In 2 years, public stroke awareness initiatives increased from 25 to 75% of countries. All countries have started programs to encourage physical activity, and there has been an increase in the number of countries that implement, at least partially, strategies to identify and treat hypertension, diabetes, and lifestyle risk factors. Programs to identify and treat dyslipidemia and atrial fibrillation still remained poor. The number of stroke centers increased from 322 to 448, all of them providing intravenous thrombolysis, with an increase in countries with stroke units. All countries have mechanical thrombectomy, but mostly restricted to a few private hospitals. Pre-hospital organization remains limited. The utilization of telemedicine has increased but is restricted to a few hospitals and is not widely available throughout the country. Patients have late, if any, access to rehabilitation after hospital discharge. Conclusion: The initiative to collaborate, exchange experiences, and unite societies and governments to improve stroke care in Latin America has yielded good results. Important advances have been made in the region in terms of increasing the number of acute stroke care services, implementing reperfusion treatments and creating programs for the detection and treatment of risk factors. We hope that this approach can reduce inequalities in stroke care in Latin America and serves as a model for other under-resourced environments.

RESUMEN

BACKGROUND: In high-income countries, the management of stroke has changed substantially over the years with the advent of thrombolysis and endovascular treatment. However, in low-income countries, such interventions may not be available, or patients may come to the hospital outside the time window no longer qualified for this therapy. Most studies on stroke units were conducted in high-income countries. Unfortunately, there has been no local multicenter data with large patient numbers showing the effectiveness of stroke units in the Southeast Asian region. AIM: To compare the outcomes of patients allocated to stroke units (based on accepted criteria) to those allocated to general neurology wards in the Philippines. METHODS: This is an open, prospective, parallel, observational comparative study of patients from 11 institutions in the Philippines. Patients were allocated either to the stroke unit or to the general neurology ward by the admitting physician based on the criteria suggested by the Stroke Trialist Collaboration Group. The primary outcome was to determine in-hospital mortality at three- and six months in both stroke units and general neurology wards. The secondary outcomes were determined by a dichotomized modified Rankin scale: (0-2) independent and (3-5) dependent. RESULTS: A total of 1025 patients were included in the study. In the primary outcome, a higher mortality rate (8.4% vs 1.0%) in the general neurology ward (p = 0.000) was seen. The six-month mortality rate was statistically significant and higher among patients admitted to the general neurology ward (3.1% vs 0.8%) (p = 0.009). Patients admitted to the stroke unit attained an independent functional outcome (mRS 0-2) as compared to the general neurology ward (73% vs 61.5%) (p = 0.000). Analysis of functionality at six months favored patients admitted in the stroke unit (88.5% vs 81.4%) as compared to the general neurology ward. CONCLUSION: Patients specifically admitted to stroke units in the Philippines based on established criteria have better outcomes than those admitted to general neurology wards.
