RESUMO
BACKGROUND AND PURPOSE: The complexity and expense of endovascular treatment (EVT) for acute ischaemic stroke (AIS) can present difficulties in bringing this approach closer to the patients. A collaborative node was implemented involving three stroke centres (SCs) within the Madrid Stroke Network to provide round-the-clock access to EVT for AIS. METHODS: A weekly schedule was established to ensure that at least one SC was 'on-call' to provide EVT for all those with moderate to severe AIS due to large vessel occlusion, >4.5 h from symptom onset, or within this time-window but with contraindication to, or failure of, systemic thrombolysis. The time-window for treatment was 8 h for anterior circulation stroke and <24 h in posterior stroke. Outcomes measured were re-canalization rates, modified Rankin Scale (mRS) score at 3 months, mortality and symptomatic intra-cranial haemorrhage (SICH). RESULTS: Over a 2-year period (2012-2013), 303 candidate patients with AIS were considered for EVT as per protocol, and 196 (65%) received treatment. Reasons for non-treatment were significant improvement (14%), spontaneous re-canalization (26%), clinical worsening (9%) or radiological criteria of established infarction (31%). Re-canalization rate amongst treated patients was 80%. Median delay from symptom onset to re-canalization was 323 min (p25; p75 percentiles 255; 430). Mortality was 11%; independence (mRS 0-2) was 58%; SICH was 3%. CONCLUSIONS: Implementation of a collaborative network to provide EVT for AIS is feasible and effective. Results are good in terms of re-canalization rates and clinical outcomes.

The usual therapy in cerebral venous sinus thrombosis (CVST) is based on anticoagulant treatment with adjusted-dose unfractionated heparin. When medical treatment fails, endovascular techniques, such as mechanical thrombectomy, are available. We report a case of a 21-year-old woman with a diagnosis of left CVST, treated by a neurointerventional approach with mechanical thrombectomy using the Penumbra(®) System. Despite the fact that only incomplete recanalization was achieved, a gradual resolution of the thrombus and a progressive clinical improvement occurred.

OBJECTIVE: This study aims to determine which factors are associated with delays in door-to needle (DTN) time in our hospital. This will help us design future strategies to shorten time to treatment with intravenous thrombolysis (IVT). METHODS: Retrospective analysis of a prospective cohort of patients with ischaemic stroke treated with IVT in our hospital between 2009 and 2012. We analysed the relationship between DTN time and the following variables: age, sex, personal medical history, onset-to-door time, pre-hospital stroke code activation, blood pressure and blood glucose level, National Institutes of Health Stroke Scale (NIHSS), computed tomography angiography (CTA) and/or doppler/duplex ultrasound (DUS) performed before IVT, time to hospital arrival, and day of the week and year of stroke. RESULTS: Our hospital treated 239 patients. Median time to treatment in minutes (IQR): onset-to-door, 84 (60-120); door-to-CT, 17 (13-24.75); CT-to needle, 34 (26-47); door-to-needle, 52 (43-70); onset-to-needle, 145 (120-180). Door-to-needle time was significantly shorter when code stroke was activated, at 51 vs. 72min (P=0.008), and longer when CTA was performed, at 59 vs. 48.5min (P=0.004); it was also longer with an onset-to-door time<90min, at 58 vs. 48min (P=0.003). The multivariate linear regression analysis detected 2 factors affecting DTN: code stroke activation (26.3% reduction; P<0.001) and onset-to-door time (every 30min of onset-to-door delay corresponded to a 4.7min increase in DTN time [P=0.02]). On the other hand, CTA resulted in a 13.4% increase in DTN (P=0.03). No other factors had a significant influence on door-to-needle time. CONCLUSIONS: This study enabled us to identify CTA and the «3-hour effect¼ as the 2 factors that delay IVT in our hospital. In contrast, activating code stroke clearly reduces DTN. This information will be useful in our future attempts to reduce door-to-needle times.

INTRODUCTION: Spontaneous spinal epidural haematoma (SSEH) has an estimated incidence of one per million inhabitants. It is classified as spontaneous when no identifiable cause can be linked to its onset. OBJECTIVE: To describe a sample of patients with SSEH and analyse variables related to its functional prognosis. PATIENTS AND METHODS: Retrospective study carried out in patients diagnosed with SSEH between 2001 and 2013 in our hospital. RESULTS: We included 13 subjects (7 men) with a mean age of 71 years. Of the total, 62% had hypertension and 54% were treated with oral anticoagulants; of the latter, 57% had an International Normalised Ratio above 3. The most frequent manifestation was spinal column pain (85%). Nearly all subjects presented an associated neurological deficit, whether sensory-motor (70%), pure motor (15%), or pure sensory (7%). Five patients underwent surgical treatment and 8 had conservative treatment. After one year, 3 of the patients treated surgically and 4 of those on conservative treatment had a score of 2 or lower on the modified Rankin Scale. Poorer prognosis was observed in patients with anticoagulant therapy, large haematomas, location in the lumbar region, and more pronounced motor disability at onset. CONCLUSIONS: Old age, hypertension, and anticoagulant therapy are the main risk factors for SSEH. The typical presentation consists of back pain with subsequent motor deficit. In patients with established motor symptoms, surgical treatment within the first 24hours seems to be the best option.

INTRODUCTION: Stroke is the main cause of admission to Neurology departments and cardioembolic stroke (CS) is one of the most common subtypes of stroke. METHODS: A multicentre prospective observational study was performed in 5 Neurology departments in public hospitals in the Region of Madrid (Spain). The objective was to estimate the use of healthcare resources and costs of acute CS management. Patients with acute CS at<48h from onset were recruited. Patients' socio-demographic, clinical, and healthcare resource use data were collected during hospitalisation and at discharge up to 30 days after admission, including data for rehabilitation treatment after discharge. RESULTS: During an 8-month recruitment period, 128 patients were recruited: mean age, 75.3±11.25; 46.9% women; mortality rate, 4.7%. All patients met the CS diagnostic criteria established by GEENCV-SEN, based on medical history or diagnostic tests. Fifty per cent of the patients had a history of atrial fibrillation and 18.8% presented other major cardioembolic sources. Non-valvular atrial fibrillation was the most frequent cause of CS (33.6%). Data for healthcare resource use, given a mean total hospital stay of 10.3±9.3 days, are as follows: rehabilitation therapy during hospital stay (46.9%, mean 4.5 days) and after discharge (56.3%, mean 26.8 days), complications (32%), specific interventions (19.5%), and laboratory and diagnostic tests (100%). Head CT (98.4%), duplex ultrasound of supra-aortic trunks (87.5%), and electrocardiogram (85.9%) were the most frequently performed diagnostic procedures. Average total cost per patient during acute-phase management and rehabilitation was 13,139. Hospital stay (45.0%) and rehabilitation at discharge (29.2%) accounted for the largest part of resources used. CONCLUSIONS: Acute CS management in the Region of Madrid resulted consumes large amounts of resources (13,139), mainly due to hospital stays and rehabilitation.

BACKGROUND AND OBJECTIVE: To update the ad hoc Committee of the Cerebrovascular Diseases Study Group of The Spanish Neurological Society guidelines on prevention of ischaemic stroke (IS) and Transient Ischaemic Attack (TIA). METHODS: We reviewed the available evidence on ischaemic stroke and TIA prevention according to aetiological subtype. Levels of evidence and recommendation levels are based on the classification of the Centre for Evidence-Based Medicine. RESULTS: In atherothrombotic IS, antiplatelet therapy and revascularization procedures in selected cases of ipsilateral carotid stenosis (70%-90%) reduce the risk of recurrences. In cardioembolic IS (atrial fibrillation, valvular diseases, prosthetic valves and myocardial infarction with mural thrombus) prevention is based on the use of oral anticoagulants. Preventive therapies for uncommon causes of IS will depend on the aetiology. In the case of cerebral venous thrombosis oral anticoagulation is effective. CONCLUSIONS: We conclude with recommendations for clinical practice in prevention of IS according to the aetiological subtype presented by the patient.

INTRODUCTION: Update of Acute Ischaemic Stroke Treatment Guidelines of the Spanish Neurological Society based on a critical review of the literature. Recommendations are made based on levels of evidence from published data and studies. DEVELOPMENT: Organized systems of care should be implemented to ensure access to the optimal management of all acute stroke patients in stroke units. Standard of care should include treatment of blood pressure (should only be treated if values are over 185/105 mmHg), treatment of hyperglycaemia over 155 mg/dl, and treatment of body temperature with antipyretic drugs if it rises above 37.5 °C. Neurological and systemic complications must be prevented and promptly treated. Decompressive hemicraniectomy should be considered in cases of malignant cerebral oedema. Intravenous thrombolysis with rtPA should be administered within 4.5 hours from symptom onset, except when there are contraindications. Intra-arterial pharmacological thrombolysis can be considered within 6 hours, and mechanical thrombectomy within 8 hours from onset, for anterior circulation strokes, while a wider window of opportunity up to 12-24 hours is feasible for posterior strokes. There is not enough evidence to recommend routine use of the so called neuroprotective drugs. Anticoagulation should be administered to patients with cerebral vein thrombosis. Rehabilitation should be started as early as possible. CONCLUSION: Treatment of acute ischaemic stroke includes management of patients in stroke units. Systemic thrombolysis should be considered within 4.5 hours from symptom onset. Intra-arterial approaches with a wider window of opportunity can be an option in certain cases. Protective and restorative therapies are being investigated.

OBJECTIVE: To update the Spanish Society of Neurology's guidelines for subarachnoid haemorrhage diagnosis and treatment. MATERIAL AND METHODS: A review and analysis of the existing literature. Recommendations are given based on the level of evidence for each study reviewed. RESULTS: The most common cause of spontaneous subarachnoid haemorrhage (SAH) is cerebral aneurysm rupture. Its estimated incidence in Spain is 9/100 000 inhabitants/year with a relative frequency of approximately 5% of all strokes. Hypertension and smoking are the main risk factors. Stroke patients require treatment in a specialised centre. Admission to a stroke unit should be considered for SAH patients whose initial clinical condition is good (Grades I or II on the Hunt and Hess scale). We recommend early exclusion of aneurysms from the circulation. The diagnostic study of choice for SAH is brain CT (computed tomography) without contrast. If the test is negative and SAH is still suspected, a lumbar puncture should then be performed. The diagnostic tests recommended in order to determine the source of the haemorrhage are MRI (magnetic resonance imaging) and angiography. Doppler ultrasonography studies are very useful for diagnosing and monitoring vasospasm. Nimodipine is recommended for preventing delayed cerebral ischaemia. Blood pressure treatment and neurovascular intervention may be considered in treating refractory vasospasm. CONCLUSIONS: SAH is a severe and complex disease which must be managed in specialised centres by professionals with ample experience in relevant diagnostic and therapeutic processes.

INTRODUCTION: Population ageing, the rising demand for healthcare, and the establishment of acute stroke treatment programs have given rise to increases in the number and complexity of neurological emergency cases. Nevertheless, many centres in Spain still lack on-call emergency neurologists. METHODS: We conducted a retrospective study to describe the role of on-call neurologists at Hospital General Universitario Gregorio Marañón, a tertiary care centre in Madrid, Spain. Sociodemographic characteristics, most common pathologies, diagnostic tests, and destination of the patients attended were recorded daily using a computer database. Results were compared with the general care data from the emergency department. RESULTS: The team attended 3234 patients (3.48% of the emergency department total). The mean number of patients seen per day was 11.15. The most frequent pathologies were stroke (34%), epilepsy (16%) and headache (8%). The mean stay in the emergency department was 7.17 hours. Hospital admission rate was 40% (7.38% of emergency hospital admissions). The main destinations for admitted patients were the stroke unit (39.5%) and the neurology department (33%). Endovascular or thrombolytic therapies were performed on 76 occasions. Doctors attended 70% of the patients during on-call hours. CONCLUSIONS: Emergency neurological care is varied, complex, and frequently necessary. Neurological cases account for a sizeable percentage of both patient visits to the emergency room and the total number of emergency admissions. The current data confirm that on-call neurologists available on a 24-hour basis are needed in emergency departments.

Intracerebral haemorrhage accounts for 10%-15% of all strokes; however it has a poor prognosis with higher rates of morbidity and mortality. Neurological deterioration is often observed during the first hours after onset and determines poor prognosis. Intracerebral haemorrhage, therefore, is a neurological emergency which must be diagnosed and treated properly as soon as possible. In this guide we review the diagnostic procedures and factors that influence the prognosis of patients with intracerebral haemorrhage and we establish recommendations for the therapeutic strategy, systematic diagnosis, acute treatment and secondary prevention for this condition.

INTRODUCTION: The A-S-C-O classification may be better than other methods for classifying ischaemic stroke by aetiology. Our aims are to describe A-S-C-O phenotype distribution (A: atherosclerosis, S: small vessel disease, C: cardiac source, O: other causes; 1: potential cause, 2: causality uncertain, 3: unlikely to be a direct cause although disease is present) and compare them to the Spanish Society of Neurology's Cerebrovascular Disease Study Group (GEECV/SEN) classification. We will also find the degree of concordance between these classification methods and determine whether using the A-S-C-O classification delivers a smaller percentage of strokes of undetermined cause. METHODS: We analysed those patients with ischaemic stroke admitted to our stroke unit in 2010 with strokes that were classified according to GEECV/SEN and A-S-C-O criteria. RESULTS: The study included 496 patients. The percentages of strokes caused by atherosclerosis and small vessel disease according to GEECV/SEN criteria were higher than the percentages for potential atherosclerotic stroke (A1) (14.1 vs. 11.9%; P=.16) and potential small vessel stroke (S1) (14.3 vs. 3%; P<.001). Cardioembolic stroke (C1) was more frequent (22.2 vs. 31%; P<.001). No differences between unusual cause of stroke and other potential causes (O1) were observed. Some degree of atherosclerosis was present in 53.5% of patients (A1, A2, or A3); 65.5% showed markers of small vessel disease (S1, S2, or S3), and 74.9% showed signs of cardioembolism (C1, C2, or C3). Fewer patients in the group without scores of 1 or 2 for any of the A-S-C-O phenotypes were identified as having a stroke of undetermined cause (46.6 vs. 29.2%; P<.001). The agreement between the 2 classifications ranged from κ<0.2 (small vessel and S1) to κ>0.8 (unusual causes and O1). CONCLUSION: Our results show that GEECV/SEN and A-S-C-O classifications are neither fully comparable nor consistent. Using the A-S-C-O classification provided additional information on co-morbidities and delivered a smaller percentage of strokes classified as having an undetermined cause.

BACKGROUND AND PURPOSE: Alteplase licensing approval in Europe does not advocate intravenous thrombolysis (IVT) for diabetic ischaemic stroke (IS) patients with previous cerebral infarction (PCI). Our aim was to assess whether concomitant diabetes mellitus (DM) and PCI are associated with symptomatic intracerebral haemorrhage (SICH) and poor outcome after IVT. METHODS: Multicentre prospective registry, which included consecutive IVT-treated, acute IS patients from January 2003 to December 2010. The frequency of SICH (SITS-MOST criteria) and 3-month outcomes (mRS) were compared between the following groups: (i) diabetic patients with PCI (DM+/PCI+); (ii) diabetic patients without PCI (DM+/PCI-); (iii) non-diabetic patients with PCI (DM-/PCI+); and (iv) patients without diabetes or PCI (DM-/PCI-). RESULTS: A total of 1475 patients were included. Thirty-four patients (2.3%) had known DM and PCI, 258 (17.5%) were diabetics without PCI, and 119 (8.1%) had a PCI and no DM. Thirty-six patients (2.6%) developed SICH, with no differences between groups (P = 985). Fifteen (40.9%) DM+/PCI+ patients, 113 (46.5%) DM+/PCI- patients, 47 (42%) DM-/PCI+ patients and 414 (40.9%) DM-/PCI- patients had mRS ≥ 3 at 3 months (P = 427). The presence neither of DM nor of PCI, nor their combination, had any impact on the risk of SICH or on outcome at 3 months after adjusting for age, stroke severity and glucose levels on admission. CONCLUSIONS: Acute IS diabetic patients with PCI who were treated with IVT had similar outcomes to patients without such history, with no increase in the rates of SICH. Thus, they should not be excluded from IVT only on the basis of DM and PCI.

OBJECTIVES: To identify possible differences in the early response to intravenous thrombolysis (IVT) or in stroke outcome at 3 months, based on stroke subtype in patients with acute ischaemic stroke (IS). METHODS: Multicentre stroke registry data were used, with prospective inclusion of consecutive patients with acute IVT-treated IS in five acute stroke units. We compared clinical improvement (National Institutes of Health Stroke Scale, NIHSS) at 24 h and at day 7 as well as functional outcome at 3 months (Modified Rankin Scale, mRS) amongst the different stroke subtypes (ICD-10). RESULTS: In total, 1479 patients were included; 178 (12%) had large vessel disease (LVD) with carotid stenosis ≥ 50%, 175 (11.8%) had other LVD, 638 (43%) had cardioembolism, 60 (4.1%) had lacunar infarction, 72 (4.9%) were patients with IS of other/unusual cause and 356 (24.1%) had unknown/multiple causes. Patients with lacunar infarction had lower stroke severity (median NIHSS 6) whilst cardioembolic IS was the most severe (median NIHSS 14) (P < 0.001). No differences in NIHSS improvement were found at 24 h. LVD patients with carotid stenosis (odds ratio 0.544; 95% CI 0.383-0.772; P = 0.001) were less likely to improve at day 7 after adjustment for age, gender, vascular risk factors and stroke severity. However, adjusted multivariate analysis showed no influence of stroke subtype on stroke outcome (mRS) at 3 months. Age, systolic blood pressure on admission and stroke severity were independently associated with mRS > 2 at 3 months. CONCLUSION: Although LVD patients with arterial stenosis ≥ 50% improve less than the other aetiologies at day 7, stroke aetiological subtype does not determine differences in IS outcome at 3 months after IVT.

OBJECTIVE: To update the ad hoc Committee of the Cerebrovascular Diseases Study Group of The Spanish Neurological Society guidelines on prevention of ischaemic stroke (IS) and transient ischaemic attack (TIA). METHODS: We reviewed available evidence on risk factors and means of modifying them to prevent ischaemic stroke and TIA. Levels of evidence and recommendation grades are based on the classification of the Centre for Evidence-Based Medicine. RESULTS: This first section summarises the recommendations for action on the following factors: blood pressure, diabetes, lipids, tobacco and alcohol consumption, diet and physical activity, cardio-embolic diseases, asymptomatic carotid stenosis, hormone replacement therapy and contraceptives, hyperhomocysteinemia, prothrombotic states and sleep apnea syndrome. CONCLUSIONS: Changes in lifestyle and pharmacological treatment for hypertension, diabetes mellitus and dyslipidemia, according to criteria of primary and secondary prevention, are recommended for preventing ischemic stroke.

INTRODUCTION: The COVID-19 pandemic has had a devastating impact on health, society and economics worldwide. Therefore, vaccines against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have recently emerged as an important measure to fight the pandemic. ChAdOx1-S (Oxford-AstraZeneca) is an adenovirus-vectored vaccine that expresses the SARS-CoV-2 spike protein. It shows an acceptable safety profile. Nevertheless, several cases of unusual thrombosis and thrombocytopenia have been reported after initial vaccination with ChAdOx1-S mimicking autoimmune heparin-induced thrombocytopenia. This condition has been called thrombosis with thrombocytopenia syndrome (TTS) and complications such as intracerebral haemorrhage have been described. CASE REPORT: We present a case of intracerebral haemorrhage after ChAdOx1-S vaccination. Middle-aged patient with no prior medical history was seen in the emergency room 16 days after the first dose of ChAdOx1-S vaccine with sudden onset left hemiplegia and severe holocranial oppressive headache. She did not receive heparin treatment in the previous 100 days. Blood test showed moderate thrombocytopenia and a right frontal lobar haemorrhage was seen on computed tomography scan, computed tomography venography was negative for thrombosis. The presence of antibodies against platelet factor 4 was confirmed. The patient's neurological condition progressively worsened. She developed a treatment resistant intracranial hypertension syndrome and she died three weeks later. CONCLUSIONS: TTS is a rare adverse effect of ChAdOx1-S vaccine, defined by the presence of thrombosis in uncommon locations. In our case we report an spontaneous intracerebral haemorrhage probable due to the thrombocytopenia related to probable TTS. It represents a rare clinical presentation of TTS.
TITLE: Hemorragia intracerebral fatal asociada al síndrome de trombosis con trombocitopenia tras la vacuna ChAdOx1-S.Introducción. La pandemia por COVID-19 ha tenido un impacto devastador en la salud, la sociedad y la economía en el mundo. Por ello, las vacunas contra el coronavirus del síndrome respiratorio agudo grave 2 (SARS-CoV-2) han surgido como medida importante para combatir la pandemia. ChAdOx1-S (Oxford-AstraZeneca) es una vacuna vectorizada por adenovirus que expresa la proteína de espiga del SARS-CoV-2. Se han notificado varios casos de trombosis y trombocitopenia inusuales tras la ChAdOx1-S que imitan la trombocitopenia autoinmune inducida por heparina. Esta situación se denomina síndrome de trombosis con trombocitopenia (STT), y se han descrito casos de hemorragia intracerebral secundaria. Caso clínico. Presentamos un caso de hemorragia intracerebral tras la vacunación con ChAdOx1-S. Una paciente de mediana edad sin antecedentes médicos de interés fue atendida en urgencias 16 días después de la primera dosis de ChAdOx1-S con una hemiplejía izquierda de inicio repentino y una cefalea opresiva holocraneal grave. No recibió heparina los 100 días anteriores. El análisis de sangre mostró trombocitopenia moderada y en la tomografía computarizada se observó una hemorragia lobar frontal derecha sin trombosis en la venografía por tomografía computarizada. Se confirmó la presencia de anticuerpos contra el factor 4 de las plaquetas en la sangre. La paciente presentó un síndrome de hipertensión intracraneal resistente al tratamiento y falleció tres semanas después. Conclusiones. El STT es un efecto adverso infrecuente de la vacuna ChAdOx1-S que se define por la presencia de trombosis en localizaciones infrecuentes. En nuestro caso, describimos una hemorragia intracerebral espontánea secundaria a la trombocitopenia desencadenada por el STT. Representa una presentación clínica poco frecuente del STT.

BACKGROUND: in-hospital strokes (IHS) are relatively frequent. Avoidable delays in neurological assessment have been demonstrated. We study the clinical characteristics, neurological care and mortality of IHS. METHODS: multi-centre 1-year prospective study of IHS in 13 hospitals. Demographic and clinical characteristics, admission diagnosis, quality of care, thrombolytic therapy and mortality were recorded. RESULTS: we included 273 IHS patients [156 men; 210 ischaemic strokes (IS), 37 transient ischaemic attacks (TIA) and 26 cerebral haemorrhages]. Mean age was 72 ± 12 years. Cardiac sources of embolism were present in 138 (50.5%), withdrawal of antithrombotic drugs in 77 (28%) and active cancers in 35 (12.8%). Cardioembolic stroke was the most common subtype of IS (50%). Reasons for admission were programmed or urgent surgery in 70 (25%), cardiac diseases in 50 (18%), TIA or stroke in 30 (11%) and other medical illnesses in 71 (26%). Fifty-two per cent of patients were evaluated by a neurologist within 3 h of stroke onset. Thirty-three patients received treatment with tPA (15.7%). Thirty-one patients (14.7%) could not be treated because of a delay in contacting the neurologist. During hospitalization, 50 patients (18.4%) died, 41 of them because of the stroke or its complications. CONCLUSIONS: cardioembolic IS was the most frequent subtype of stroke. Cardiac sources of embolism, active cancers and withdrawal of antithrombotic drugs constituted special risk factors for IHS. A significant proportion of patients were treated with thrombolysis. However, delays in contacting the neurologist excluded a similar proportion of patients from treatment. IHS mortality was high, mostly because of stroke.

INTRODUCTION: The information obtained from the Emergency Medical Chart (EMC) is a key factor for the correct management of acute stroke. Our aim is to determine if the use of a pro-forma (PF) for filling in the EMC improves the quality of the clinical information. MATERIAL AND METHODS: A PF was created from a list of 26 key-items considered important to be recorded in an EMC. We compared the number of items recorded in the EMC of patients admitted to our Stroke Unit (SU) in January-February 2009 (before PF was introduced) with the data obtained with the PF (April-May, 2009). We also analysed the agreement with the final diagnosis on discharge from the SU. RESULTS: A total of 128 EMC were analysed, and the PF was used in 48 cases. The mean number of recorded items was 20.5 for the PF group and 13.7 for the non-PF charts (P<.001). Sixteen of the 26 items were recorded significant more frequently (P<.05) in the PF Group. The most notable scores being: previous baseline situation (100% vs. 51%), previous Modified Rankin scale score (94% vs. 1%), time of symptom onset (100% vs. 85%), time of neurological evaluation (100% vs. 39%), NIHSS score (92% vs. 30%), ECG results (88% vs. 59%), time of perform brain scan (60% vs. 1%). Diagnostic agreement: nosological/syndromic diagnosis: PF group: 94%, Non-PF group: 60% (P<.001), topographic diagnosis: PF: 71%, Non-PF: 53% (P=.03), aetiological diagnosis: PF: 25%, Non-PF: 9% (P=.01). CONCLUSIONS: The use of a PF improves the quantity and quality of the information, and offers a better diagnostic accuracy.

INTRODUCTION: Recent analyses emphasise that The Benchmark Stroke Door-to-Needle Time (DNT) should be 30min. This study aimed to determine if a new in-hospital IVT protocol is effective in reducing door-to-needle time and correcting previously identified factors associated with delays. MATERIAL AND METHODS: In 2014, we gradually introduced a series of measures aimed to reduce door-to-needle time for patients receiving IVT, and compared it before (2009-2012) and after (2014-2017) the new protocol was introduced. RESULTS: The sample included 239 patients before and 222 after the introduction of the protocol. Median overall door-to-needle time was 27min after the protocol was fully implemented (a 48% reduction on previous door-to-needle time [52min], P<.001)]. Median door-to-needle time was lower when pre-hospital code stroke was activated (22min). We observed a 26-min reduction in the median time from onset to treatment (P<.001). After the protocol was implemented, the "3-hour-effect" did not affect door-to-needle time (P=.98). Computed tomography angiography studies performed before IVT were associated with increased door-to-needle time (P<.001); however, the test was performed after IVT was started in most cases. CONCLUSIONS: Hospital reorganisation and multidisciplinary collaboration brought median door-to-needle time below 30min and corrected previously identified delay factors. Furthermore, overall time from onset to treatment was also reduced and more stroke patients were treated within 90min of symptom onset.
