[Three-month functional prognosis of patients hospitalised due to acute ischaemic stroke in Aragon: Rregional analysis of the impact of COVID-19]. / Pronóstico funcional a 3 meses de pacientes hospitalizados por ictus isquémico agudo en Aragón: análisis regional de la repercusión de la COVID-19.

Introduction: The COVID-19 pandemic has had an impact on ischaemic stroke management, with a reported decrease in hospital admissions, and even disruptions in healthcare and increased in-hospital mortality. However, there is a lack of evidence on the impact of the pandemic on functional prognosis. The aim of this study is to analyse the effect of the COVID-19 pandemic on the 3-month functional outcomes of patients hospitalised due to acute ischaemic stroke in Aragon (Spain). Materil and methods: We reviewed the data of all patients admitted due to ischaemic stroke to any hospital in our regional healthcare system between 30 December 2019 and 3 May 2020. We compared modified Rankin Scale scores and mortality at 3 months in patients hospitalised before and after the declaration of a state of emergency due to the COVID-19 pandemic. Results: In total, 318 patients with acute ischaemic stroke met our inclusion criteria. No differences were observed between periods in global or specific characteristics, with the exception of a higher proportion of patients older than 80 years during the first period (42.2% vs. 29.0%, P=.028). In the comparative analysis, we found no significant differences in mortality (12.3 vs. 7.9, P=.465) or in the proportion of patients with modified Rankin Scale scores ≤ 2 (57.7% vs. 57.1%, P=.425) at 3 months. Conclusion: To our knowledge, this is the first study to analyse the impact of COVID-19 pandemic on the 3-month functional outcomes of patients with ischaemic stroke. In our region, there has been no increase in rates of mortality or disability at 3 months in patients admitted due to ischaemic stroke during the pandemic.

Ischaemic stroke in the time of coronavirus disease 2019.

BACKGROUND AND PURPOSE: Stroke assistance is facing changes and new challenges since COVID-19 became pandemic. A variation on the patient influx might be one of the greater concerns, due to fewer people coming to emergency departments or coming too late. However, no data quantifying this have been published until now. The aim was to analyse the impact of the COVID-19 epidemic outbreak on hospital stroke admissions and their characteristics in our region. METHODS: The data of every patient admitted to any hospital of our healthcare system with a diagnosis of ischaemic stroke between 30 December 2019 and 19 April 2020 were reviewed. Demographic and clinical data were recorded and compared between periods before and after the setting of the state of emergency secondary to the COVID-19 outbreak. RESULTS: In total, 354 patients with ischaemic stroke were admitted in our study period. There was a weekly average of 27.5 cases before the setting of the state of emergency against 12 afterwards (P < 0.001). This drop in stroke cases occurred progressively from week 11, persisting in time despite the decrease in confirmed cases of COVID-19. No differences in the proportion of intravenous thrombolysis (21.1% vs. 21.5%, P = 0.935) or endovascular therapy (12.4% vs. 15.2%, P = 0.510) were found, nor in other demographic or clinical characteristics except for median onset-to-door time (102 vs. 183 min, P = 0.015). CONCLUSIONS: This observational study offers the perspective of a whole region in one of the countries more heavily stricken by the SARS-CoV-2 epidemic and shows that the decrease of stroke events, since the beginning of the COVID-19 outbreak, happened globally and without any specific patient distribution.

Impact of COVID-19 outbreak in reperfusion therapies of acute ischaemic stroke in northwest Spain.

BACKGROUND AND PURPOSE: Spain has been one of the countries more heavily stricken by SARS-CoV-2, which has had huge implications for stroke care. The aim was to analyse the impact of the COVID-19 epidemic outbreak on reperfusion therapies for acute ischaemic stroke in the northwest of Spain. METHODS: This was a Spanish multicentre retrospective observational study based on data from tertiary hospitals of the NORDICTUS network. All patients receiving reperfusion therapy for ischaemic stroke between 30 December 2019 and 3 May 2020 were recorded, and their baseline, clinical and radiological characteristics, extra- and intra-hospital times of action, Code Stroke activation pathway, COVID-19 status, reperfusion rate, and short-term outcome before and after the setting of the emergency state were analysed. RESULTS: A total of 796 patients received reperfusion therapies for ischaemic stroke. There was a decrease in the number of patients treated per week (46.5 patients per week vs. 39.0 patients per week, P = 0.043) and a delay in out-of-hospital (95.0 vs. 110.0 min, P = 0.001) and door-to-needle times (51.0 vs. 55.0, P = 0.038). Patients receiving endovascular therapy obtained less successful reperfusion rates (92.9% vs. 86.6%, P = 0.016). COVID-19 patients had more in-hospital mortality. CONCLUSION: A decrease in the number of patients benefiting from reperfusion therapies was found, with a delay in out-of-hospital and door-to-needle times and worse reperfusion rates in northwest Spain. COVID-19 patients had more in-hospital mortality.

Impact of a series of measures for optimisation hospital code stroke care on door-to-needle times.

INTRODUCTION: Time continues to be a fundamental variable in reperfusion treatments for acute ischaemic stroke. Despite the recommendations made in clinical guidelines, only around one-third of these patients receive fibrinolysis within 60minutes. In this study, we describe our experience with the implementation of a specific protocol for patients with acute ischaemic stroke and evaluate its impact on door-to-needle times in our hospital. METHODS: Measures were gradually implemented in late 2015 to shorten stroke management times and optimise the care provided to patients with acute ischaemic stroke; these measures included the creation of a specific on-call neurovascular care team. We compare stroke management times before (2013-2015) and after (2017-2019) the introduction of the protocol. RESULTS: The study includes 182 patients attended before implementation of the protocol and 249 attended after. Once all measures were in effect, the overall median door-to-needle time was 45minutes (vs 74 minutes before, a 39% reduction; P<.001), with 73.5% of patients treated within 60minutes (a 47% increase; P<.001). Median overall time to treatment (onset-to-needle time) was reduced by 20minutes (P<.001). CONCLUSIONS: The measures included in our protocol achieved a significant, sustained reduction in door-to-needle times, although there remains room for improvement. The mechanisms established for monitoring outcomes and for continuous improvement will enable further advances in this regard.

[Moyamoya in Aragon: epidemiology and self-perception of quality of life]. / Moyamoya en Aragón. Epidemiología y calidad de vida autopercibida.

INTRODUCTION: Moyamoya angiopathy is a vasculopathy caused by stenosis/occlusion of one or both intracranial internal carotid arteries. Although more common in Eastern countries, its prevalence is increasing in the West. An angioresonance or angiography is essential for its diagnosis. There are two options for treatment: conservative (medical) treatment or surgical bypass techniques. PATIENTS AND METHODS: Nineteen patients were selected using International Classification of Diseases codes, and their demographic characteristics and health outcomes were studied. They were administered a scale for the screening of anxious-depressive syndrome (the Hospital Anxiety and Depression Scale - HADS) and another scale for self-perceived quality of life (SF-36). After applying the inclusion/exclusion criteria, eight of these patients were studied. RESULTS: Nineteen patients were studied (52.63% male, 57.89% European) and the Aragonese prevalence was estimated at 1.37/100,000 inhabitants. The most frequent clinical presentation was ischaemic stroke (73.68%). The HADS detected two positive cases of anxiety and one case of depression. According to the SF-36, the worst self-rated aspects were vitality (median: 35/100) and general health (median: 42.5/100), while the best rated was physical function (mean: 93.57/100). CONCLUSIONS: This is the Spanish series with the highest prevalence and the only one that addresses self-perceived health and screening of the anxious-depressive syndrome. Further research is needed to address this entity and determine its true prevalence in the West.

TITLE: Moyamoya en Aragón. Epidemiología y calidad de vida autopercibida.Introducción. La angiopatía de moyamoya es una vasculopatía originada por la estenosis/oclusión de una o ambas carótidas internas intracraneales. Aunque es más frecuente en países orientales, está aumentando su prevalencia en Occidente. Para su diagnóstico es imprescindible una angiorresonancia o una angiografía. En su tratamiento hay dos opciones: el tratamiento conservador (médico) o las técnicas quirúrgicas de bypass. Pacientes y métodos. Se seleccionó a 19 pacientes mediante códigos de la Clasificación internacional de enfermedades, y se estudiaron sus características demográficas y resultados en salud. Se les administró una escala para el cribado de síndrome ansiosodepresivo ­escala de ansiedad y depresión hospitalaria (HADS)­ y otra de autopercepción de calidad de vida (SF-36). De estos pacientes, se estudió a ocho al aplicar los criterios de inclusión/exclusión. Resultados. Se estudió a 19 pacientes (52,63%, hombres; 57,89%, europeos) y se estimó la prevalencia aragonesa en 1,37/100.000 habitantes. La clínica más frecuente fue el ictus isquémico (73,68%). La HADS detectó dos casos positivos para ansiedad y un caso de depresión. Según el SF-36, los aspectos peor autopercibidos fueron la vitalidad (mediana: 35/100) y la salud general (mediana: 42,5/100); mientras que el mejor valorado fue la función física (media: 93,57/100). Conclusiones. Se trata de la serie española con mayor prevalencia y la única que aborda la salud autopercibida y el cribado del síndrome ansiosodepresivo. Son necesarios más estudios que permitan abordar esta entidad y cuál es la verdadera prevalencia en Occidente.

Validation of the Spanish-language version of the simplified modified Rankin Scale telephone questionnaire.

INTRODUCTION: The modified Rankin Scale (mRS) is the main functional assessment tool used after stroke. The simplified mRS questionnaire (smRSq) has recently been validated in English, and represents a simpler, reliable scale with an excellent reproducibility via telephone. The present study aims to validate a Spanish-language version of the telephone smRSq. METHODS: We conducted a prospective cohort study, assessing 50 patients 3 months after they presented an ischaemic stroke. We assessed the Spanish-language smRSq by telephone and in person, the mRS with a structured interview, the Spanish-language smRSq, and the Stroke Impact Scale-16. Inter-rater reliability, test-retest reliability, construct validity, and criterion validity were assessed. RESULTS: Inter-rater reliability showed strong agreement (k = 0.810); test-retest reliability and criterion validity showed moderate agreement (k = 0.639 and k = 0.759, respectively), and construct validity showed moderate agreement (Spearman correlation coefficient = -0.728). CONCLUSIONS: The Spanish-language telephone smRSq is reliable and simple, and saves time in the functional assessment after a stroke.

Incidence, outcomes, and associated factors of isolated striatocapsular infarct after mechanical thrombectomy.

OBJECTIVE: To describe baseline and procedural characteristics and clinical outcomes of isolated striatocapsular infarct (iSCI) after mechanical thrombectomy in patients with large-vessel occlusion of the anterior cerebral circulation and its clinical outcome. METHODS: We performed a longitudinal study including all patients treated with mechanical thrombectomy at our centre between 2015 and 2017; patients were divided into 2 groups (iSCI and non-iSCI) according to whether they presented iSCI in a control CT scan at 24 hours. RESULTS: Of the 83 patients identified, 22.9% developed an iSCI. There were no statically significant differences in baseline characteristics or in reperfusion times. Patients presenting iSCI showed better collateral circulation and better reperfusion rates in the bivariate analysis. No significant difference was observed for mortality at discharge or at 3 months, or for functional prognosis at 3 months. CONCLUSIONS: Even if successful reperfusion is achieved, iSCI is a common sequela, independently of reperfusion time, especially in patients with good collateral circulation.

Epidemiology and characteristics of ischaemic stroke in young adults in Aragon.

INTRODUCTION: Stroke affects around 15 million people per year, with 10%-15% occurring in individuals under 50 years old (stroke in young adults). The prevalence of different vascular risk factors and healthcare strategies for stroke management vary worldwide, making the epidemiology and specific characteristics of stroke in each region an important area of research. This study aimed to determine the prevalence of different vascular risk factors and the aetiology and characteristics of ischaemic stroke in young adults in the autonomous community of Aragon, Spain. METHODS: A cross-sectional, multi-centre study was conducted by the neurology departments of all hospitals in the Aragonese Health Service. We identified all patients aged between 18 and 50 years who were admitted to any of these hospitals with a diagnosis of ischaemic stroke or TIA between January 2005 and December 2015. Data were collected on demographic variables, vascular risk factors, and type of stroke, among other variables. RESULTS: During the study period, 786 patients between 18 and 50 years old were admitted with a diagnosis of ischaemic stroke or TIA to any hospital of Aragon, at a mean annual rate of 12.3 per 100 000 population. The median age was 45 years (IQR: 40-48 years). The most prevalent vascular risk factor was tobacco use, in 404 patients (51.4%). The majority of strokes were of undetermined cause (36.2%), followed by other causes (26.5%). The median NIHSS score was 3.5 (IQR: 2.0-7.0). In total, 211 patients (26.8%) presented TIA. Fifty-nine per cent of the patients admitted with a diagnosis of ischaemic stroke (10.3%) were treated with fibrinolysis. CONCLUSIONS: Ischaemic stroke in young adults is not uncommon in Aragon, and is of undetermined aetiology in a considerable number of cases; it is therefore necessary to implement measures to improve study of the condition, to reduce its incidence, and to prevent its recurrence.

Three-month functional prognosis of patients hospitalised due to acute ischaemic stroke in Aragon: regional analysis of the impact of COVID-19.

[Characteristics of the stroke alert process attended by 061 ARAGON assistance units from 2010 to 2016. Factors influencing times of response and access to fibrinolytic treatment]. / Casuística de códigos ictus atendidos por 061 ARAGÓN en el período 2010-2016. Factores que influyen en los tiempos de respuesta y de acceso a la fibrinólisis.

AIM: To study the response times of stroke code assistance by care units of 061 ARAGON, analyzing factors involved and their relationship with availability to fibrinolytic treatment in the hyperacute phase. PATIENTS AND METHODS: Transversal descriptive study on outpatient care from the registry of cases attended by 061 ARAGON health care units to patients with stroke code during the period 2010-2016. RESULTS: A total of 1743 patients were attended (54.6% males), with a mean age of 72.83 ± 13.1 years. There was a higher number of strokes attended in 2015 and 2016 (372 and 366 respectively), compared to the average of 201 strokes per year in the rest of the years. 27,2% of patients were treated between 08:00-11:59 h, the most frequent time interval. Regarding the time, it took to take care of the patient, the average was 71.93 ± 33.64 minutes with a longer response time in Teruel. When influence of the hour interval on the percentage of cases treated with fibrinolysis was analyzed, a higher rate of fibrinolysis was observed when it was activated between 12:00-15:59 h (28.1%). CONCLUSIONS: In 55,3% of patients, the 061 response time was greater than 60 minutes, but this time were not conditioned by the activation time. However, there were differences in the percentage of cases fibrinolysed in the different time intervals, suggesting that factors other than the response time of 061 influence the indication of fibrinolytic treatment.

TITLE: Casuística de códigos ictus atendidos por 061 ARAGÓN en el período 2010-2016. Factores que influyen en los tiempos de respuesta y de acceso a la fibrinólisis.Objetivo. Estudiar los tiempos de respuesta en la atención al código ictus por unidades asistenciales del 061 ARAGÓN, analizando los factores implicados y su relación con el acceso al tratamiento fibrinolítico en la fase hiperaguda. Pacientes y métodos. Estudio descriptivo transversal sobre la asistencia extrahospitalaria a partir del registro de casos atendidos por unidades asistenciales del 061 ARAGÓN a pacientes con código ictus durante el período 2010-2016. Resultados. Se recogieron 1.743 pacientes con código ictus (54,6%, varones), con una edad media de 72,83 ± 13,1 años. El número de ictus atendidos en 2015 y 2016 (372 y 366, respectivamente) fue mayor que la media de 201 ictus anuales en el resto de los años. El 27,2% de los pacientes fueron atendidos entre las 08:00 y las 11:59 h, intervalo horario con mayor frecuentación. Respecto al tiempo que se tardó en atender al paciente, la media fue de 71,93 ± 33,64 minutos, con ma­yor tiempo de respuesta en Teruel. Cuando se analizó la influencia del intervalo horario sobre el porcentaje de casos tratados con fibrinólisis, se observó una mayor tasa de fibrinólisis cuando se activó entre las 12:00 y las 15:59 h (28,1%). Conclusión. En el 55,3% de los pacientes, el tiempo de respuesta del 061 fue mayor de 60 minutos, pero este tiempo no se vio condicionado por la hora de activación. Sin embargo, sí había diferencias en el porcentaje de casos de fibrinólisis en los diferentes intervalos horarios, lo que sugiere que factores distintos al tiempo de respuesta del 061 influyen en la indicación del tratamiento fibrinolítico.

[Influence of mechanical thrombectomy on the incidence of isolated striatocapsular infarction and a description of its clinical characteristics]. / Influencia de la trombectomia mecanica en la incidencia de infarto estriatocapsular aislado y descripcion de sus caracteristicas clinicas.

INTRODUCTION: The great vulnerability of the striatocapsular region to ischaemia means that mechanical thrombectomy has its limitations in occlusions of large-calibre vessels when it comes to preventing the striatocapsular region from undergoing infarction. AIMS: To analyse the effect of endovascular treatment on the incidence of isolated striatocapsular infarction (iSCI) and to describe its clinical characteristics. PATIENTS AND METHODS: We conducted a retrospective study to analyse the incidence of iSCI following treatment of cerebral reperfusion. The baseline and clinical characteristics of the patients identified with iSCI and the incidence of iSCI is compared between two groups according to the availability of mechanical thrombectomy: one (pre-thrombectomy group) that received intravenous fibrinolysis as the only treatment for cerebral reperfusion available in that moment; and another (post-thrombectomy group) that received a mechanical thrombectomy with or without intravenous fibrinolysis. RESULTS: Of the 390 patients who received reperfusion, 8.2% had iSCI. Of the 135 patients treated with intravenous fibrinolysis, 4.4% (n = 6) developed iSCI (pre-thrombectomy group), and of the 255 patients treated in the post-thrombectomy group, iSCI was observed in 10.2%. The statistical analysis of the incidence of iSCI between the two groups showed significant differences (p = 0.034). A sensory-motor clinical picture was the most frequent among the patients with iSCI (63.33%), with a frequency of cortical symptoms of 55.17%. CONCLUSIONS: According to the data, there has been an increase in the incidence of iSCI in our setting following the establishment of mechanical thrombectomy.

Estudio retrospectivo en el que se analiza la incidencia de IECa tras el tratamiento de reperfusion cerebral. Se describen las caracteristicas basales y clinicas de los pacientes identificados con IECa y se compara la incidencia del IECa entre dos grupos segun la disponibilidad de trombectomia mecanica: uno (grupo pretrombectomia) que recibio fibrinolisis intravenosa como unico tratamiento de reperfusion cerebral disponible en ese momento, y otro (grupo postrombectomia) que recibio trombectomia mecanica con o sin fibrinolisis intravenosa. Resultados. Del total de 390 pacientes reperfundidos, un 8,2% tuvo un IECa. De 135 pacientes tratados con fibrinolisis intravenosa, un 4,4% (n = 6) desarrollo un IECa (grupo pretrombectomia), y de 255 pacientes tratados en el grupo postrombectomia, se visualizo IECa en un 10,2%. El analisis estadistico de la incidencia de IECa entre ambos grupos mostro diferencias significativas (p = 0,034). La clinica sensomotora fue la mas frecuente entre los pacientes con IECa (63,33%), con una frecuencia de sintomas corticales de un 55,17%. Conclusiones. Segun los datos, hemos presenciado un aumento en la incidencia de IECa en nuestro medio tras la instauracion de la trombectomia mecanica.

Stroke care programme in Aragon (PAIA): strategy and outcomes for the period 2009-2014. / Programa de Atención al Ictus en Aragón (PAIA). Estrategia del cambio y resultados en el periodo 2009-2014.

INTRODUCTION: In 2008, stroke mortality, morbidity, and disability rates in Aragon were higher than the average in Spain. These data underscored the need to develop a stroke care programme (PAIA). MATERIAL AND METHODS: We present the dynamics of planning, implementation, evaluation, and improvement developed between 2009 and 2014 as well as the results of the PAIA after that 5-year period. RESULTS: Structure, processes, and outcomes have improved with reference to the key indicators of healthcare (audit: 2008, 2010, 2012) among others: stroke rate in 2013 was 2.07 (2.36 in 2008); 78% of strokes were managed in stroke units in 2014 (30% in 2008); rate of fibrinolysis was 8.3% in 2014 (4.4% in 2010); fibrinolysis was administered in secondary hospitals (30% of the total); fibrinolysis was administered by Telestroke in 9%; stroke mortality decreased (38%); 67.7 years of potential life lost (YPLL) in 2013 (144 in 2008); nurse training; development of neurosonology; networking; sharing protocols and best practices between health sectors, etc. CONCLUSIONS: Integrated process management and multidisciplinary teams distributed and deployed over an entire territory with established protocols, references, evaluations, and continuous development, have been proven powerful tools to ensure both quality and equality. The PAIA is a good example of clinical governance and networking due to its dynamic and sustained improvement and cooperation between clinicians.

[Signs predicting early growth of intracerebral haemorrhage in computer tomography without enhancement and mortality]. / Signos predictores de crecimiento precoz de la hemorragia intracerebral en la tomografia computarizada sin contraste y mortalidad.

INTRODUCTION: Intracerebral haemorrhage is associated with high morbidity and mortality, and an increase in its volume in the early phases entails a poorer prognosis. The blend sign, the heterogeneous density, the irregular morphology and a fluid level in the haematoma are related to an early growth of the haematoma. AIM: To determine whether these four characteristics are associated with greater mortality at 7, 30 and 90 days of the occurrence of the intracerebral haemorrhage. PATIENTS AND METHODS: A retrospective cohort study that included all the patients attended in our hospital between 2010 and 2015 for spontaneous intracerebral haemorrhage with a computed tomography brain scan performed in the first six hours following the onset of symptoms. RESULTS: Of the 158 patients included in the sample, 23 (14.6%) presented blend sign; 39 (24.7%), heterogeneity; 53 (33.5%), irregularity; and 33 (20.9%), fluid level. In the bivariate analysis, only heterogeneity and irregularity were associated with increased mortality at 7, 30 and 90 days. In the multivariate logistic regression analysis, previous treatment with an antiplatelet drug, a score on the Glasgow Coma Scale below 13 and irregularity were associated with higher mortality in the first seven days. CONCLUSION: The study shows an association between irregularity of the haematoma and mortality in the first seven days. Irregularity would allow identification of patients with a more unfavourable prognosis; in these cases, strict surveillance, especially of factors related to the growth of the haematoma, could improve their prognosis.

TITLE: Signos predictores de crecimiento precoz de la hemorragia intracerebral en la tomografia computarizada sin contraste y mortalidad.Introduccion. La hemorragia intracerebral esta asociada a una elevada morbimortalidad y su aumento de volumen en fases iniciales conlleva un peor pronostico. El signo de la mezcla, la densidad heterogenea, la morfologia irregular y un nivel liquido en el hematoma se relacionan con un crecimiento precoz del hematoma. Objetivo. Determinar si esas cuatro caracteristicas se asocian a una mayor mortalidad a los 7, 30 y 90 dias de ocurrida la hemorragia intracerebral. Pacientes y metodos. Estudio de cohortes retrospectivo que incluyo a todos los pacientes atendidos en nuestro hospital, entre 2010 y 2015, por una hemorragia intracerebral espontanea con tomografia computarizada cerebral realizada en las primeras seis horas tras el inicio de los sintomas. Resultados. De los 158 pacientes incluidos, 23 (14,6%) presentaban signo de la mezcla, 39 (24,7%) heterogeneidad, 53 (33,5%) irregularidad y 33 (20,9%) nivel liquido. En el analisis bivariante, solo la heterogeneidad y la irregularidad se asociaron a mayor mortalidad a los 7, 30 y 90 dias. En el analisis por regresion logistica multivariante, el tratamiento previo con antiagregante plaquetario, una puntuacion en la escala de coma de Glasgow menor de 13 y la irregularidad se asociaron a una mayor mortalidad en los siete primeros dias. Conclusion. El estudio muestra asociacion entre la irregularidad del hematoma y la mortalidad en los siete primeros dias. La irregularidad permitiria identificar a pacientes con peor pronostico, en los que una vigilancia estricta, especialmente de factores relacionados con el crecimiento del hematoma, podria mejorar su pronostico.

[Auditing as a tool for ongoing improvement in the Stroke Care Plan of the Region of Aragon]. / El audit como herramienta de mejora continua en el Plan de Atencion al Ictus de Aragon.

INTRODUCTION: The Aragon Stroke Care Plan (PAIA) was created in 2008 within the framework of the Spanish National Health System. Monitoring hospital care of strokes by means of periodic audits was defined as one of its lines of work. AIM: To determine the quality of the hospital care process for stroke patients in Aragon by using quality indicators. MATERIALS AND METHODS: Three audits were carried out (in the years 2008, 2010 and 2012) following the same methodology, based on the retrospective review of a representative sample of admissions due to stroke in each of the general hospitals belonging to the Aragonese Health Service. Information was collected on 48 indicators selected according to their scientific evidence or clinical relevance. RESULTS: Altogether 1011 cases were studied (331 in the first audit, and 340 in the second and the third). Thirty-one indicators showed a significant improvement (some of the most notable being the indicators of quality of the medical record, neurological assessment, initial preventive measures and, especially relevant, performing the swallowing test), two underwent a decline in their condition (related with rehabilitation treatment) and 15 did not register any significant variation. CONCLUSIONS: The implementation of the PAIA has given rise to a notable improvement in most of the quality indicators evaluated, which reflects an ongoing improvement in hospital stroke care. The progressive generalisation of specialised care and the creation of stroke units are some of the determining factors.

TITLE: El audit como herramienta de mejora continua en el Plan de Atencion al Ictus de Aragon.Introduccion. El Plan de Atencion al Ictus de Aragon (PAIA) se creo en 2008 en el marco de la Estrategia Nacional en Ictus del Sistema Nacional de Salud. La monitorizacion de la atencion hospitalaria al ictus mediante auditorias periodicas se definio como una de sus lineas de trabajo. Objetivo. Determinar la calidad del proceso asistencial hospitalario prestado al paciente con ictus en Aragon mediante el uso de indicadores de calidad. Materiales y metodos. Se realizaron tres audits (en los años 2008, 2010 y 2012) siguiendo la misma metodologia, basada en la revision retrospectiva de una muestra representativa de ingresos por ictus en cada uno de los hospitales generales del Servicio Aragones de Salud. Se recogio informacion sobre 48 indicadores seleccionados segun su evidencia cientifica o relevancia clinica. Resultados. Se estudiaron 1.011 casos (331 en el primer audit, y 340 en el segundo y en el tercero). Treinta y un indicadores presentaron una mejoria significativa (entre ellos destacan los indicadores de calidad de la historia clinica, de evaluacion neurologica, las medidas preventivas iniciales y, con especial relevancia, la realizacion de test de deglucion), dos sufrieron empeoramiento (relacionados con el tratamiento rehabilitador) y 15 no registraron variaciones significativas. Conclusiones. La implantacion del PAIA ha supuesto una mejoria notable en la mayoria de los indicadores de calidad evaluados, reflejo de una mejora continua en la atencion hospitalaria del ictus. La generalizacion progresiva de la atencion especializada y la creacion de las areas de ictus son algunos de los factores determinantes.
