Length of Hospitalization and Mortality among Stroke Patients before and after the Implementation of a Specialized Unit: A Retrospective Cohort Study Using Real-World Data from One Reference Hospital in Southern Brazil.

Stroke constitutes a significant global cause of mortality and disability. The implementation of stroke units influences hospital quality indicators, guiding care management. We aimed to compare hospital length of stay (LOS), in-hospital mortality, and post-discharge mortality between stroke patients admitted in the pre- and post-implementation periods of a stroke unit in a public hospital in southern Brazil. This retrospective cohort study used real-world data from one reference hospital, focusing on the intervention (stroke unit) and comparing it to the general ward (control). We analyzed the electronic medical records of 674 patients admitted from 2009 to 2012 in the general ward and 766 patients from 2013 to 2018 in the stroke unit. Admission to the stroke unit was associated with a 43% reduction in the likelihood of prolonged hospitalization. However, there was no significant difference in the risk of in-hospital mortality between the groups (Hazard ratio = 0.90; Interquartile range = 0.58 to 1.39). The incidence of death at three, six and twelve months post-discharge did not differ between the groups. Our study results indicate significant improvements in care processes for SU patients, including shorter LOS and better adherence to treatment protocols. However, our observations revealed no significant difference in mortality rates, either during hospitalization or after discharge, between the SU and GW groups. While SU implementation enhances efficiency in stroke care, further research is needed to explore long-term outcomes and optimize management strategies.

Challenges in adapting a stroke unit in a middle-income country: warning about costs and underfunding to achieve the Brazilian Ministry of Health's benchmark.

Background: Since the implementation of the stroke care line in Brazil, the relationship (adequacy) of costs spent during hospitalization with the Brazilian Ministry of Health indicators for a stroke unit have not yet been analyzed. Aims: This study aimed to assess the adequacy of a comprehensive stroke center for key performance indicators and analyze the costs involved in hospitalization. We verified the association between stroke severity at admission and care costs during hospitalization. Methods: A retrospective medical chart review of 451 patients was performed using semiautomatic electronic data from a single comprehensive stroke center in Brazil between July 2018 and January 2020. Clinical and resource utilization data were collected, and the mean acute treatment cost per person was calculated. The Kruskal-Wallis test with Dunn's post-test was used to compare the total costs between stroke types and reperfusion therapies. A robust linear regression test was used to verify the association between stroke severity at hospital admission and the total hospitalization costs. Good adequacy rates were observed for several indicators. Results: Data from 451 patients were analyzed. The stroke unit had good adaptation to key performance indicators, but some critical points needed revision and improvement to adapt to the requirements of the Ministry of Health. The average total cost of the patient's stay was the USD 2,637.3, with the daily hospitalization, procedure, operating room, and materials/medication costs equating to USD 2,011.1, USD 220.7, USD 234.1, and USD 98.8, respectively. There was a positive association between the total cost and length of hospital stay (p < 0.001). Conclusion: The stroke unit complied with most of the main performance indicators proposed by the Brazilian Ministry of Health. Underfunding of the costs involved in the hospitalization of patients was verified, and high costs were associated with the length of stay, stroke severity, and mechanical thrombectomy.

Capsular warning syndrome and its clinical awareness and therapeutic approach: two case reports and a systematic review of the literature.

Introduction: Capsular warning syndrome (CWS) is characterized by recurrent stereotyped episodes of unilateral transient motor and/or sensory symptoms affecting the face and upper and lower limbs, without cortical signs in 24 h and with a high risk of developing stroke. Among the possible underlying mechanisms, small perforating artery disease is the most common. The aim was to assess the most common risk factors, the therapeutic alternatives, and the different outcomes in patients with CWS, along with the presentation of two cases treated in our Emergency Department. Methods: Stroke Code, launched at our institution in January 2017, was triggered 400 times, and by December 2022, 312 patients were admitted as having an acute ischemic stroke. Among them, two of them fulfilled the criteria of CWS. A systematic search was carried out in PubMed, Scopus, and Web of Science databases to seek demography and therapeutic approaches in CWS. Results: Of 312 cases, two with acute ischemic stroke exhibited CWS. The first patient had six events of right hemiparesis with recovery in 10-30 min; after MRI and digital subtraction angiography (DSA), he received apixaban and clopidogrel; however, a day after admission, he developed ischemic infarction with partial recovery. The second patient presented five transient events of right hemiparesis. After MRI and DSA with an intra-arterial infusion of nimodipine, oral aspirin, and ticagrelor, he presented another event-developing stroke and was discharged with partial recovery. A systematic review found 190 cases of CWS in 39 articles from 1993 to 2022. Most were male subjects (66.4%), and hypertension (60%), smoking (36%), diabetes (18%), and dyslipidemia (55%) were the most common risk factors. Over 50% of the cases were secondary to small perforating artery disease. The most commonly used treatments were dual antiplatelet therapy (DAT), recombinant tissue plasminogen activator, and anticoagulant therapy (ACT), where the combination of DAT plus ACT was linked to the most positive functional outcomes (82.6%). Conclusion: Our cases fit with the description of patients with partial recovery and risk factors (hypertension, diabetes, and smoking) in male patients. There is a lack of evidence regarding the best treatment option; dual antiplatelet therapy and anticoagulation therapy are strong contenders for a favorable result.

Organization and Implementation of a Stroke Center in Panamá, a Model for Implementation of Stroke Centers in Low and Middle Income Countries.

Background: Stroke is the second leading cause of death and disability worldwide. Stroke centers have become a central component of modern stroke services in many high-income countries, but their feasibility and efficacy in low, middle, and emerging high-income countries are less clear. Also, despite the availability of international guidelines, many hospitals worldwide do not have organized clinical stroke care. We present a methodology to help hospitals develop stroke centers and review quality data after implementation. Objectives: To describe and compare demographics, performance, and clinical outcomes of the Pacífica Salud, Hospital Punta Pacífica (PSHPP) stroke center during its first 3 years 2017-2019. Methods: Pacífica Salud, Hospital Punta Pacífica was organized to implement protocols of care based on the best practices by international guidelines and a quality improvement process. The methodology for implementation adapts a model for translating evidence into practice for implementation of evidence-based practices in medicine. This is a retrospective study of prospectively collected quality data between March of 2017 to December of 2019 for patients admitted to PSHPP with primary diagnosis stroke. Data collected include demographics, clinical data organized per the Joint Commission's STK Performance Measures, door to needle, door to groin puncture, 90 day modified Rankin Score, and hemorrhagic complications from IV thrombolysis and mechanical thrombectomy (MT). Primary outcome: year over year proficiency in documenting performance measures. Secondary outcome: year over year improvement. Results: A total of 143 patients were admitted for acute ischemic stroke, TIA, or hemorrhagic stroke. Of these, 36 were admitted in 2017, 50 in 2018, and 57 in 2019. Performance measure proficiency increased in the year-over-year analysis as did the total number of patients and the number of patients treated with IV thrombolysis and MT. Conclusions: We present the methodology and results of a stroke program implementation in Panamá. This program is the first in the country and in Central America to achieve Joint Commission International (JCI) certification as a Primary Stroke Center (PSC). We postulate that the dissemination of management guidelines is not sufficient to encourage the development of stroke centers. The application of a methodology for translation of evidence into practice with mentorship facilitated the success of this program.

[Importance of the forewarning system and assistance center selection in acute stroke]. / Importancia del sistema de preaviso y elección del centro asistencial en el accidente cerebrovascular agudo.

Acute ischemic stroke (AIS) is a time-dependent emergency, since the greatest impact depends on the time elapsed to treatment. The objective of this work was to analyze door to needle (DTN) and start treatment (STT) times and the effect of pre-notification system (PNS) and the appropriate choice of the healthcare center on these variables. An observational study with data obtained from records of patients admitted to the Stroke Unit (SU) was conducted between August 2015 to December 2019. We analyzed the number of intravenous thrombolytic treatments (IVT), DTN and STT and compared them according to PNS use, direct arrival at the center with SU or arrival at another center for subsequent referral. An overall of 472 patients were hospitalized during the studied period and the treatment was performed in 143 out of 265 patients. One hundred thirty-seven patients arrived from another center, 70 received IVT. Average DNT with PNS and without PNS were 41 ± 23 and 81 ± 44 minutes, respectively (p = 0.001). STT on direct arrival to SU was 159 ± 59 minutes and to another center for referral was 199 ± 44 (p = 0.001). The use of a PNS and the direct choice of a center where IVT is performed significantly improve treatment.

El accidente cerebrovascular (ACV) es una urgencia tiempo dependiente, ya que las conductas de mayor impacto pronóstico dependen del tiempo trascurrido. El objetivo de este trabajo fue analizar nuestros tiempos puerta aguja (TPA), comienzo aguja (TCA) y el efecto que tiene sobre estos el sistema preaviso y la elección adecuada del centro asistencial. Se realizó un estudio observacional con datos obtenidos de historias clínicas de pacientes internados en la unidad de ACV. Analizamos el número de tratamientos trombolíticos endovenosos, entre agosto 2015 y diciembre 2019. Comparamos TPA según utilización de pre-aviso, llegada directa por sus propios medios vs. en ambulancia sin pre-aviso, y TCA según llegada directa al centro con unidad de ACV vs. llegada a otro centro para posterior derivación. De 265 pacientes en ventana terapéutica, se realizó tratamiento en 143. Llegaron 137 pacientes derivados de otro centro, 70 recibieron tratamiento trombolítico. El TPA con sistema preaviso y sin preaviso fue 41 ± 23 (media ± DE) y 81 ± 43 minutos, respectivamente (p = 0.001). El TPA con llegada directa por sus propios medios 79 ± 43 y en ambulancia sin preaviso 84 ± 44 minutos (p = 0.7) a unidad de ACV. El TCA en llegada directa a unidad de ACV fue 159 ± 59 y a otro centro para su derivación 199 ± 44 minutos (p = 0.001). La utilización de un sistema de preaviso y la elección directa de un centro con unidad de ACV son medidas clave para reducir los tiempos de tratamiento.

Uso y resultados de la fibrinolisis intravenosa en una unidad cerebrovascular / Use and results of intravenous fibrinolysis in a stroke unit

Resumen La fibrinólisis intravenosa con activador del plasminógeno tisular recombinante (rTPA) y la utilización de unidades cerradas, demostraron disminuir sustancialmente la morbimortalidad en pacientes con accidente cerebrovascular isquémico (ACVi). Sin embargo, los datos publicados en Argentina son escasos. Describimos la experiencia en la utilización de fibrinólisis en pacientes con ACVi agudo antes y después de la implementación de una unidad cerebrovascular (UCV) en un Centro Integral de Neurología Vascular de la Ciudad de Buenos Aires durante 17 años. Se realizó un análisis retrospectivo de pacientes consecutivos tratados con rTPA entre enero 2003 y diciembre 2019. Se evaluaron tiempos de tratamiento, de internación, complicaciones post tratamiento y discapacidad a 3 meses. Para su análisis se evaluaron los períodos pre y post apertura de la UCV, período 1 (P1 de 2003-2011) y P2 (2012 -2019). Se realizó fibrinolisis intravenosa en 182 pacientes. La apertura de UCV resultó en aumento del porcentaje de fibrinólisis sobre el total de los ACVi ingresados (4% en P1 vs. 10% en P2, p < 0.001), acortamiento del tiempo puerta-aguja (75 minutos en P1 vs. 53 minutos en P2, p < 0.00001) y mayor proporción de pacientes tratados dentro de los 60 minutos del ingreso hospitalario (36% en P1 vs. 76% en P2, p < 0.00001). Además, hubo reducción de la mediana de internación de 9 días en P1 a 5 días en P2 (p < 0.00001). En conclusión, la UCV parece optimizar la utilización de fibrinólisis en el ACVi agudo, aumentando el porcentaje de pacientes tratados, reduciendo el tiempo puerta-aguja y disminuyendo el de internación.

Abstract Intravenous fibrinolysis with recombinant tissue plasminogen activator (rTPA) and use of stroke units improve morbidity and mortality in patients with acute ischemic stroke (AIS). However, data published in Argentina are scarce. We describe the experience in the use of fibrinolysis in patients with acute ischemic stroke (AIS) before and after the implementation of a stroke unit in a Comprehensive Stroke Center in Buenos Aires during the last 17 years. Retrospective analysis of consecutive patients treated with rTPA between January 2003 and December 2019. Treatment times, hospitalization time, post-treatment complications and disability at 3 months were evaluated. For the analysis, the pre and post opening periods of the stroke unit were evaluated, Period 1 (P1, from 2003 to 2011) and Period 2 (P2, from 2012 to 2019). Intravenous fibrinolysis was performed in 182 patients. Opening of the stroke unit resulted in an increase in the percentage of fibrinolysis over the total number of admitted strokes (4% in P1 vs. 10% in P2, p < 0.001), shortening of the door-to-needle time (75 minutes in P1 vs. 53 minutes in P2, p < 0.00001) and higher proportion of patients treated within 60 minutes of hospital admission (36% in P1 vs. 76% in P2, p < 0.00001). In addition, there was a reduction in the median hospital stay from 9 days in P1 to 5 days in P2 (p < 0.00001). In conclusion, stroke units seem to optimize the use of fibrinolysis in acute stroke, increasing the percentage of patients treated, reducing door-to-needle time, and reducing hospitalization time.

Perfil do atendimento de pacientes com acidente vascular cerebral em um hospital filantrópico do sul de Santa Catarina e estudo de viabilidade para implantação da Unidade de AVC / Profile of the care of patients with vascular cerebral accident in a phantantrophic hospital of the south of Santa Catarina and feasibility study for implementation of the Stroke Unit

O objetivo do estudo foi conhecer o perfil de atendimento dos pacientes com Acidente Vascular Cerebral (AVC) em um hospital da região Sul de Santa Catarina, no ano de 2016, e avaliar a viabilidade de implantação de uma Unidade de AVC. Trata-se de um estudo epidemiológico observacional e descritivo, realizado por coleta de dados em prontuários eletrônicos de pacientes com AVC e pela aplicação do Formulário de Vistoria para Gestores constante na Portaria nº. 665/2012 do Ministerio da Saúde, que trata da habilitação dos Centros de AVC. Dos 208 casos, 81,3% tiveram AVC isquêmico, os principais fatores de risco foram Hipertensão Arterial (78,4%) e Diabete Melito (36,1%). O intervalo de tempo entre início dos sintomas e o primeiro atendimento variou de 1,5 a 5,5 horas, entre o atendimento inicial e a Tomografia Computadorizada (TC) 1,3h e entre TC e trombolítico foi de 1,12h. Das intervenções apenas 9,2% usaram trombolítico, a principal complicação foi infecção (21,6%) e o tempo de internação foi de 5 dias. Quanto às Unidade de AVC, a Instituição preenche requisitos para Unidades Tipo I. A partir dos resultados conclui-se que houve dificuldade em determinar o tempo de início dos sintomas e, com isso, a indicação da terapia trombolítica. O tempo de internação foi semelhante a de um Hospital com Centro de AVC implantado. Há condições de receber uma Unidade de AVC do tipo I com porte para se adequar a unidades mais complexas, no hospital em estudo.

The aim of this study was to know the profile of stroke patients seen at a hospital in the southern region of Santa Catarina, in 2016, and to evaluate the feasibility of a Stroke Unit. This is an observational and descriptive epidemiological study, carried out by data collection in electronic medical records of stroke patients and by the application of the Inspection Form for Managers contained in Ordinance no. 665/2012 of the Brazilian Ministry of Health, that deals with the habilitation of Stroke Centers. Of the 208 cases, 81.3% had ischemic stroke and the main risk factors were Hypertension (78.4%) and Diabetes Melitos (36.1%). The period between the onset of symptoms and first health care ranged from 1.5 to 5.5 hours; between initial health care and CT scan, 1.3 hours; and between CT and thrombolytic therapy was 1.12 hours. Only 9.2% of the interventions used thrombolytic therapy, the main complication was infection (21.6%) and the hospitalization period was 5 days. The institution fulfills the requirements for Type I Stroke Units. It was difficult to determine the time of onset of symptoms and, therefore, the indication of thrombolytic therapy. The period of hospital stay was similar to that of a Hospital with a Stroke Center implanted. There are conditions in the hospital under study to receive a Type I or more complex Stroke Unit.

Acute Treatment of Stroke (Except Thrombectomy).

PURPOSE OF REVIEW: The management of patients with acute stroke has been revolutionized in recent years with the advent of new effective treatments. In this rapidly evolving field, we provide an update on the management of acute stroke excluding thrombectomy, looking to recent, ongoing, and future trials. RECENT FINDINGS: Large definitive trials have provided insight into acute stroke care including broadening the therapeutic window for thrombolysis, alternatives to standard dose alteplase, the use of dual antiplatelet therapy early after minor ischemic stroke, and treating elevated blood pressure in intracerebral hemorrhage. Further ongoing and future trials are eagerly awaited in this ever-expanding area. Although definitive trials have led to improvements in acute stroke care, there remains a need for further research to improve our understanding of pathophysiological mechanisms underlying different stroke types with the potential for treatments to be tailored to the individual.

Análisis de una Cohorte de Pacientes con ACV del Joven: Hospital de Clínicas, Montevideo / Analysis of a cohort of patients with young man's stroke: Hospital of Clinics, Montevideo / Análise de uma coorte de pacientes com AVC do joven: Hospital de Clínicas, Montevidéu

Resumen: Introducción: El ataque cerebro-vascular (ACV) es un importante problema de salud pública. Se define ACV en el joven a aquel que se presenta entre los 15-45 años. El objetivo primario de este trabajo es describir las características epidemiológicas, clínicas, imagenológicas, etiopatogénicas y terapéuticas de los pacientes con ACV en el joven. Materiales y Métodos: Se trata de un estudio retrospectivo y descriptivo, acerca de una cohorte de pacientes que presentaron ACV en el joven asistidos en el Hospital de Clínicas de Montevideo en el período comprendido entre junio de 2007 y junio de 2014. Resultados: Se incluyeron 50 pacientes que representaron el 5,6 % de todos los ACV en el período comprendido en el estudio. La media de edad fue de 33 años. En cuanto a la naturaleza, el 64% fueron isquémicos y el 36% hemorrágicos. Según la clasificación TOAST, la etiología más frecuente fue la criptogenética (34%). Respecto a la etiología de las hemorragias intracerebrales la mitad correspondió a malformaciones vasculares. Discusión: El porcentaje de ACV del joven fue algo menor que el descrito en otras comunicaciones. Comparado con el ACV en todas las edades, la hemorragia cerebral aumenta su proporción, si bien la naturaleza isquémica sigue predominando. La causa más frecuente de ACV isquémico del joven fue la criptogenética, seguida de la cardioembolia y las causas inhabituales. Las disecciones arteriales igualaron en prevalencia a la ateromatosis de grandes vasos. Este hecho es similar a lo descrito por la mayoría de los autores. Conclusiones: Si bien la etiología más prevalente de hemorragia parenquimatosa fueron las malformaciones vasculares, la cantidad de hematomas hipertensivos no fue despreciable a estas edades.

Abstract: Introduction: Stroke is an important public health issue. Stroke in the young is defined as the one who presents between 15 and 45 years old. The primary objective of this study is to describe the epidemiological, clinical, imaging, etiopathogenic and therapeutic characteristics of stroke in young patients. Materials and Methods: This was a retrospective and descriptive study of a cohort of patients who presented with stroke in the young assisted at the Hospital de Clínicas in Montevideo in the period between June 2007 and June 2014. Results: We have included fifty patients which accounted for 5.6% of all stroke in the period covered by the study. The mean age was 33 yo. As for nature, 64% were ischemic and 36% hemorrhagic. According to the TOAST classification, the most common etiology was cryptogenetic (34%). Regarding the etiology of intracerebral hemorrhages, half corresponded to vascular malformations. Discussion: The proportion of stroke in young people was somewhat lower than that described in other communications. Compared with stroke in all ages, cerebral hemorrhage increases its proportion, although the ischemic nature continues to predominate. The most common cause of ischemic stroke was cryptogenetic, followed by cardioembolism and unusual causes. Arterial dissections matched the prevalence of atheromatosis of large vessels. This fact is similar to that described by most authors. Conclusions: Although the most prevalent etiology of parenchymal hemorrhage were vascular malformations, the number of hypertensive hematomas was not negligible at these ages.

Resumo: Introdução: O ataque cerebrovascular (AVC) é um importante problema de saúde pública. A ACV é definida no jovem que aparece entre 15 a 45 anos. O objetivo primário deste trabalho é descrever as características epidemiológicas, clínicas, de imagem, etiopatogênicas e terapêuticas de pacientes com AVC em jovens. Materiais e métodos: Trata-se de um estudo retrospectivo e descritivo sobre uma coorte de pacientes que se apresentaram com AVC no jovem atendido no Hospital de Clínicas de Montevidéu no período de junho de 2007 a junho de 2014. Resultados: Cinquenta pacientes foram incluídos, representando 5,6% de todos os casos de AVC no período coberto pelo estudo. A idade média foi de 33 anos. Em relação à natureza, 64% eram isquêmicos e 36% eram hemorrágicos. Segundo a classificação TOAST, a etiologia mais freqüente foi a criptogenética (34%). Em relação à etiologia das hemorragias intracerebrais, metade correspondeu a malformações vasculares. Discussão A porcentagem do derrame do jovem foi um pouco menor do que a descrita em outras comunicações. Em comparação com o AVC em todas as idades, a hemorragia cerebral aumenta sua proporção, embora a natureza isquêmica continue a predominar. A causa mais freqüente de acidente vascular cerebral isquêmico do jovem foi criptogenética, seguida por cardioembolismo e causas incomuns. Dissecções arteriais igualaram a prevalência de ateromatose de grandes vasos. Este fato é semelhante ao descrito pela maioria dos autores. Conclusões: Embora a etiologia mais prevalente da hemorragia parenquimatosa tenha sido a malformação vascular, o número de hematomas hipertensivos não foi desprezível nessas idades.

Trombólisis intravenosa en pacientes con accidente cerebrovascular isquémico: Experiencia de un Hospital del Caribe Colombiano / Intravenous thrombolysis in patients with ischemic stroke: Experience from a Colombian Caribbean Hospital

RESUMEN INTRODUCCIÓN: Las guías de ACV isquémico establecen dentro del algoritmo de manejo la implementación de la terapia trombolítica intravenosa como una de las estrategias de abordaje del evento agudo que ha demostrado reducir los niveles de discapacidad en los pacientes. OBJETIVO: Describir el impacto de la realización de trombólisis intravenosa en pacientes con accidente cerebro-vascular isquémico, teniendo como referencia escalas de medición de funcionalidad y pronóstico. MATERIALES Y MÉTODOS: Se realizó un estudio descriptivo longitudinal en pacientes que recibieron tratamiento fibrinolítico en la Fundación Hospital Universidad del Norte (octubre 2011 - marzo 2016) teniendo en cuenta aspectos demográficos, clínicos, factores de riesgo y seguimiento a los 30 y 90 días para determinar el pronóstico y la mortalidad según escala modificada de Rankin. RESULTADOS: La población elegible consta de 27 pacientes cuya edad promedio fue de 65 años. La mayor prevalencia se presentó en el género femenino. El factor de riesgo más frecuente fue la hipertensión arterial (19/27). Se realizó manejo inicial de acuerdo al protocolo institucional de la unidad de stroke. Se describen tiempos promedio en cada etapa de la atención médica desde el inicio de los síntomas hasta la realización de la trombolisis. Durante la realización de la intervención terapéutica se documentó las complicaciones que justificaron la suspensión del manejo. Se reportó transformación hemorrágica del ACV y muerte secundaria a ello. La funcionalidad fue valorada con escala NIHSS al ingreso y egreso del paciente, el pronóstico y mortalidad se evaluaron con escala modificada de Rankin, que evidenció que más del 50 % de los pacientes obtuvieron una puntuación entre 0 y 1 a los 90 días postrombólisis. CONCLUSIONES: El estudio presenta limitantes dadas principalmente por el tamaño de la muestra, pero cabe resaltar que refleja la experiencia de un centro universitario y busca establecer y/o generar una base de datos importante a nivel regional que permita ser punto de referencia y suministrar información para futuros estudios.

SUMMARY INTRODUCTION: The ischemic stroke guidelines establish within the management algorithm the implementation of intravenous thrombolytic therapy as one of the strategies to approach the acute event that has been shown to reduce levels of disability in patients. OBJECTIVE: To describe the impact of intravenous thrombolysis performed on patients with ischemic stroke, taking into account functionality and prognosis measuring scales. MATERIALS AND METHODS: We conducted a descriptive longitudinal study on patients to whom intravenous thrombolysis were performed at the Fundación Hospital Universidad del Norte ( October 2011 - March 2016) taking into account the demographics aspects as well as risk factors including a 30 and 90 day follow up to determine prognosis and mortality using the modified Rankin scale. RESULTS: The study consisted of 27 patients whose average age was 65 years, finding a higher prevalence within female patients and A frequent risk factor of hypertension (19/27). Initial management was performed according to the institutional protocol from the stroke unit. Average times were shown at each stage of care, from the onset of symptoms to thrombolysis. During the intervention, some complications were documented which justified the suspension of the treatment. There was hemorrhagic transformation of stroke reported leading to secondary death. Functionality was assessed with the NIHSS scale at patient's admission and discharge, prognosis and mortality were assessed with a modified Rankin scale, which showed that more than 50% of the patients scored between 0 and 1 at 90 days post-thrombolysis. CONCLUSION: The study has limitations in order to establish conclusions statistically significant, but it does reflect the experience of a university center with an effective therapeutic intervention and looks to create a database in the region that can be use like a reference for other studies.

Experience on Mechanical Thrombectomy for Acute Stroke Treatment in a Brazilian University Hospital.

BACKGROUND: Brazil is a developing country struggling to reduce its extreme social inequality, which is reflected on shortage of health-care infrastructure, mainly to the low-income class, which depends exclusively on the public health system. In Brazil, less than 1% of stroke patients have access to intravenous thrombolysis in a stroke unit, and constraints to the development of mechanical thrombectomy in the public health system increase the social burden of stroke. OBJECTIVE: Report the feasibility of mechanical thrombectomy as part of routine stroke care in a Brazilian public university hospital. METHODS: Prospective data were collected from all patients treated for acute ischemic stroke with mechanical thrombectomy from June 2011 to March 2016. Combined thrombectomy was performed in eligible patients for intravenous thrombolysis if they presented occlusion of large artery. For those patients ineligible for intravenous thrombolysis, primary thrombectomy was performed as long as there was no evidence of significant ischemia for anterior circulation stroke (Alberta Stroke Program Early CT score >6) within a 6-hour time window, and also for those patients with wake-up stroke or posterior circulation stroke, regardless of the time of symptoms onset. RESULTS: A total of 161 patients were evaluated, resulting in an overall successful recanalization rate of 76% and symptomatic intracranial hemorrhage rate of 6.8%. At 3 months, 36% of the patients had modified Rankin Scale score less than or equal to 2. The overall mortality rate was 23%. CONCLUSION: Our study, the first ever large series of mechanical thrombectomy in Brazil, demonstrates acceptable efficacy and safety results, even under restricted conditions outside the ideal scenario of trial studies.

Infarto Cerebral del territorio Vértebro-Basilar: Comunicación de una serie de pacientes asistidos en el Hospital de Clínicas de Montevideo / Cerebral infarction vertebrobasilar territory: Communication of a number of patients assisted at the Hospital de Clinicas in Montevideo

Introducción: El ataque cerebro vascular tiene una elevada incidencia y mortalidad en Uruguay representando, aquellos de la circulación posterior, un porcentaje importante de ellos. En este estudio describimos características basales, clínicas, diagnósticas y terapéuticas de una serie de pacientes con ataque cerebro vascular de la circulación posterior. Material y métodos: Estudio observacional descriptivo. Inclusión: pacientes con diagnóstico de ataque cerebro vascular de la circulación posterior atendidos en el Hospital de Clínicas entre junio de 2007 y 2014. Resultados: Se incluyeron 140 pacientes con una edad media de 68 años y elevada frecuencia de factores de riesgo clásicos para enfermedad cerebro vascular. Predominó la clínica cerebelosa y piramidal, con un puntaje medio bajo en la escala de NIHSS (5,2) y una baja sensibilidad de la Tomografía de cráneo para el diagnóstico. La etiología determinada más prevalente fue la cardioembolia. Un quinto de los pacientes consultó antes de las 4,5 horas y el 3,8% de los pacientes fue tratado con trombolisis iv. Discusión y comentarios: Se trata de la mayor serie de ataque cerebro vascular de la circulación posterior reportada en nuestro país, la forma de presentación fue similar a la descrita en la literatura. La escala de NIHSS infravaloró la severidad de este tipo de ataque cerebro vascular. La tomografia de cráneo tuvo baja sensibilidad diagnóstica y el porcentaje de resonancias magnéticas realizadas fue bajo. Un bajo número de pacientes consultó en ventana para trombolisis iv y solo al 3,8% de los casos se le realizó dicho tratamiento.

Introduction:The incidence and mortality of stroke in Uruguay is high. Posterior circulation strokes represent a significant percentage of them. In this study we describe baseline characteristics, clinical presentation, diagnostic test and therapy in a cohort of patients with stroke of posterior circulation. Method: Descriptive observational study. Inclusion: patients with a diagnosis of PC stroke admitted to Hospital de Clinicas between June 2007 and 2014. Results: 140 patients were included. Mean age was 68 years and a high frequency of classic risk factors for cerebrovascular disease was found. Cerebellar and pyramidal clinic were the most frecuent, with a low median score in the NIHSS scale (5.2) and low sensitivity of the craneal tomography for the diagnosis. The most prevalent etiology was cardioembolism. A fifth of patients consulted before 4.5 hours and 3.8% of patients were treated with iv thrombolysis. Discussion and comments: This is the largest series of PC strokes reported in our country. Clinical presentation was similar to that described in the literature. NIHSS scale underestimated the severity of this type of stroke. Craneal tomograhphy had low diagnostic sensitivity and the number of magnetic resonances performed was low. A small number of patients consulted on time for iv thrombolysis and only 3.8% of cases underwent such treatment.

Characterization of patients treated by rehabilitation service after establishing of an acute stroke unit in a Brazilian hospital.

[Purpose] The study aimed to characterize patients treated by rehabilitation section after establishment of an acute stroke unit. [Subjects and Methods] Medical consultation records of individuals with ischemic stroke were studied retrospectively, excluding individuals with hemorrhagic stroke, thrombolysis, previous Modified Rankin Scale ≥ 1, prior stroke, structural bone deformities, associated neurological disease, and prior cognitive deficit. The data evaluated were age, gender, etiology, localization, treatment received, ictus onset, hospitalization time, discharge date, and date of first evaluation at the rehabilitation center. The Modified Rankin Scale in 90 days after ictus was utilized to measure functional incapacity with the individuals divided into two groups, before and after acute stroke unit implementation (2010). Functional incapacity was compared between before and after acute stroke unit implementation by the Mann-Whitney test, χ(2) test and Fisher's exact test. [Results] The medical records of 170 patients were evaluated. In the group evaluated after 2010, the patients were significantly older and presented a shorter time between hospitalization and discharge, shorter time until the first evaluation in rehabilitation, and increased percentage of mild incapacity (Modified Rankin Scale = 0 to 2). [Conclusion] After acute stroke unit implementation, the patients treated in the rehabilitation section presented a shorter hospitalization time and rehabilitation delay and less functional incapacity.

Impact of stroke unit in a public hospital on length of hospitalization and rate of early mortality of ischemic stroke patients / Impacto da unidade de AVC em hospital publico sobre a hospitalizacao e mortalidade no acidente vascular cerebral isquemico

We ascertained whether a public health stroke unit reduces the length of hospitalization, the rate of inpatient fatality, and the mortality rate 30 days after the stroke. Methods We compared a cohort of stroke patients managed on a general neurology/medical ward with a similar cohort of stroke patients managed in a str oke unit. The in-patient fatality rates and 30-day mortality rates were analyzed. Results 729 patients were managed in the general ward and 344 were treated at a comprehensive stroke unit. The in-patient fatality rates were 14.7% for the general ward group and 6.9% for the stroke unit group (p<0.001). The overall mortality rate 30 days after stroke was 20.9% for general ward patients and 14.2% for stroke unit patients (p=0.005). Conclusions We observed reduced in-patient fatalities and 30-day mortality rates in patients managed in the stroke unit. There was no impact on the length of hospitalization. .

Past, present, and future of stroke in middle-income countries: the Brazilian experience.

BACKGROUND: Stroke is one of the major public health challenges in middle-income countries. Brazil is the world's sixth largest economy but was clearly behind the milestones in the fight against stroke, which is the leading cause of death and disability in the country. Nevertheless, many initiatives are now reshaping stroke prevention, care, and rehabilitation in the country. AIMS: The present article discusses the evolution of stroke care in Brazil over the last decade. METHODS: We describe the main characteristics of stroke care before 2008; a pilot study in a Southern Brazilian city between 2008 and 2010, the Brazilian Stroke Project initiative; and the 2012 National Stroke Policy Act. RESULTS: The National Stroke Project was followed by a major increased on the number of stroke center in the country. The key elements of the 2012 National Stroke Policy Act included: definition of the requirements and levels of stroke centers; improved reimbursement for stroke care; promotion of stroke telemedicine; definition of the Line of Stroke Care (to integrate available resources and other health programs); increased funding for stroke rehabilitation; funding for training of healthcare professionals and initiatives to increase awareness about stroke within the population. CONCLUSIONS: The evolution of stroke care in Brazil over the last decade is a pathway that exemplifies the challenges that middle-income countries have to face in order to improve stroke prevention, treatment and rehabilitation. The reported Brazilian experience can be extrapolated to understand the past, present, and future of stroke care in middle-income countries.

Validation of the scandinavian stroke scale in a multicultural population in Brazil.

BACKGROUND: The objective of this study was to evaluate the consistency, coherence, and interobserver reliability of the Portuguese version of the Scandinavian Stroke Scale (SSS) in a multicultural population of stroke. METHODS: The SSS was translated, culturally adapted, and applied by two independent investigators. This was a randomized transverse study involving two groups: group 1 included 20 patients in the acute phase and group 2 included 20 patients in the subacute phase after stroke was confirmed by computed tomography with a pre-stroke modified Rankin Scale score of 0. Each patient also underwent National Institutes of Health Stroke Scale (NIHSS) evaluation at hospital entry and at the time of the SSS evaluation for correlation with our current standard hospital practice. Consistency and coherence were analyzed by Cronbach's α and interobserver reliability by κ. RESULTS: Forty patients were evaluated with 0.88 consistency and coherence in both stroke phases. Mean interobserver κ was 0.76, with reliability considered excellent and good for most scale items, and moderate for only the facial palsy item. CONCLUSION: The SSS is adequate and validated to study post-stroke patients in a multicultural Brazilian population and in the Portuguese language.
