Background and purpose
The existence of contraindications to intravenous thrombolysis (IVT) is considered a criterion for direct transfer of patients with suspected acute stroke to ...thrombectomy‐capable centers in the prehospital setting. Our aim was to assess the utility of this criterion in a setting where routing protocols are defined by the Madrid – Direct Referral to Endovascular Center (M‐DIRECT) prehospital scale.
Methods
This was a post hoc analysis of the M‐DIRECT study. Reported contraindications to IVT were retrospectively collected from emergency medical services reports and categorized into late window, anticoagulant treatment and other contraindications. Final diagnosis and treatment rates were compared between patients with and without reported IVT contraindications and according to anticoagulant treatment or late window categories.
Results
The M‐DIRECT study included 541 patients. Reported IVT contraindications were present in 227 (42.0%) patients. Regarding final diagnosis no significant differences were found between patients with or without reported IVT contraindications: ischaemic stroke (any) 65.6% vs. 62.1%, ischaemic stroke with large vessel occlusion (LVO) 32.2% vs. 28.3%, hemorrhagic stroke 15.4% vs. 15.6%, stroke mimic 18.9% vs. 22.3% respectively. Amongst patients with LVO, endovascular thrombectomy (EVT) was performed less often in the presence of IVT contraindications (56.2% vs. 74.2%). M‐DIRECT‐positive patients had higher rates of LVO and EVT compared with M‐DIRECT‐negative patients independent of reported IVT contraindications.
Conclusions
Reported IVT contraindications alone do not increase EVT likelihood and should not be considered to determine routing in urban stroke networks.
Background and purpose
For patients with acute ischaemic stroke due to large‐vessel occlusion, it has recently been shown that mechanical thrombectomy (MT) with stent retrievers is better than ...medical treatment alone. However, few hospitals can provide MT 24 h/day 365 days/year, and it remains unclear whether selected patients with acute stroke should be directly transferred to the nearest MT‐providing hospital to prevent treatment delays. Clinical scales such as Rapid Arterial Occlusion Evaluation (RACE) have been developed to predict large‐vessel occlusion at a pre‐hospital level, but their predictive value for MT is low. We propose new criteria to identify patients eligible for MT, with higher accuracy.
Methods
The Direct Referral to Endovascular Center criteria were defined based on a retrospective cohort of 317 patients admitted to a stroke center. The association of age, sex, RACE scale score and blood pressure with the likelihood of receiving MT were analyzed. Cut‐off points with the highest association were thereafter evaluated in a prospective cohort of 153 patients from nine stroke units comprising the Madrid Stroke Network.
Results
Patients with a RACE scale score ≥ 5, systolic blood pressure <190 mmHg and age <81 years showed a significantly higher probability of undergoing MT (odds ratio, 33.38; 95% confidence interval, 12–92.9). This outcome was confirmed in the prospective cohort, with 68% sensitivity, 84% specificity, 42% positive and 94% negative predictive values for MT, ruling out 83% of hemorrhagic strokes.
Conclusions
The Direct Referral to Endovascular Center criteria could be useful for identifying patients suitable for MT.
The COVID-19 pandemic has resulted in complete saturation of healthcare capacities, making it necessary to reorganise healthcare systems. In this context, we must guarantee the provision of acute ...stroke care and optimise code stroke protocols to reduce the risk of SARS-CoV-2 infection and rationalise the use of hospital resources. The Madrid Stroke multidisciplinary group presents a series of recommendations to achieve these goals.
We conducted a non-systematic literature search using the keywords "stroke" and "COVID-19" or "coronavirus" or "SARS-CoV-2." Our literature review also included other relevant studies known to the authors. Based on this literature review, a series of consensus recommendations were established by the Madrid Stroke multidisciplinary group and its neurology committee.
These recommendations address 5 main objectives: 1) coordination of action protocols to ensure access to hospital care for stroke patients; 2) recognition of potentially COVID-19-positive stroke patients; 3) organisation of patient management to prevent SARS-CoV-2 infection among healthcare professionals; 4) avoidance of unnecessary neuroimaging studies and other procedures that may increase the risk of infection; and 5) safe, early discharge and follow-up to ensure bed availability. This management protocol has been called CORONA (Coordinate, Recognise, Organise, Neuroimaging, At home).
The recommendations presented here may assist in the organisation of acute stroke care and the optimisation of healthcare resources, while ensuring the safety of healthcare professionals.
INTRODUCTIONThe overload of the healthcare system and the organisational changes made in response to the COVID-19 pandemic may be having an impact on acute stroke care in the Region of ...Madrid.METHODSWe conducted a survey with sections addressing hospital characteristics, changes in infrastructure and resources, code stroke clinical pathways, diagnostic testing, rehabilitation, and outpatient care. We performed a descriptive analysis of results according to the level of complexity of stroke care (availability of stroke units and mechanical thrombectomy).RESULTSThe survey was completed by 22 of the 26 hospitals in the Madrid Regional Health System that attend adult emergencies, between 16 and 27 April 2020. Ninety-five percent of hospitals had reallocated neurologists to care for patients with COVID-19. The numbers of neurology ward beds were reduced in 89.4% of hospitals; emergency department stroke care pathways were modified in 81%, with specific pathways for suspected SARS-CoV2 infection established in 50% of hospitals; and SARS-CoV2-positive patients with acute stroke were not admitted to neurology wards in 42%. Twenty-four hour on-site availability of mechanical thrombectomy was improved in 10 hospitals, which resulted in a reduction in the number of secondary hospital transfers. The admission of patients with transient ischaemic attack or minor stroke was avoided in 45% of hospitals, and follow-up through telephone consultations was implemented in 100%.CONCLUSIONSThe organisational changes made in response to the SARS-Co2 pandemic in hospitals in the Region of Madrid have modified the allocation of neurology department staff and infrastructure, stroke units and stroke care pathways, diagnostic testing, hospital admissions, and outpatient follow-up.

In a population-based study of the incidence of stroke conducted on a broad denominator, it is wise first to carry out a pilot study.
To present the results of the pilot phase of the study on stroke ...incidence in Spain, entitled Iberictus.
Population of the study: all cases involving the first episode of acute cerebrovascular disease (stroke or transient ischaemic attack) diagnosed among residents over 17 years of age with their habitual place of abode registered in the areas of study between 15th and 31st October 2005 (total denominator: 1,440,997 inhabitants).
prospective, hospital records (basic minimum data set, discharge abstracts) and casualty department registers. Standardised definitions: diagnostic categorisation and pathological, topographical and aetiological classification. Inter-observer agreement analysis among researchers (kappa).
A total of 128 cases were identified. Age range, 37-103 years; mean age, 75.7 +/- 13.4 years; 54% were females. In all, 71.1% of the cases were collected by means of a basic minimum data set. There were 91 ischaemic events (29.7% atherothrombotic and 29.7% cardioembolic). Of the 15 haemorrhagic strokes, 40% due to arterial hypertension, six were lobar hemispheric, six were deep basal ganglia, and there were three cerebellar haemorrhages. The incidence of stroke was seen to increase exponentially with age. Inter-observer agreement was good for the classifications that were employed (range of kappa indices, 0.57-0.78). Several problems were detected and corrected in the fieldwork.
The Iberictus pilot study yielded data that were consistent with the literature and provided us with the opportunity to detect and correct issues that would hinder us from conducting the main study.
Epidemiological data on the incidence of cerebrovascular diseases in our country are scarce. A representative population-based study with a large denominator is required.
To present the design of the ...study on stroke incidence in Spain, entitled Iberictus.
We conducted a prospective, population-based study on the incidence of strokes and transient ischemic attacks, in which it is possible to distinguish: 1) population with a steady risk, which was well defined and had a broad denominator. We included all the cases in which the first episode of acute cerebrovascular disease was diagnosed among those over the age of 17 years (with no upper age limit) with their habitual residence in the areas of study between the 1st January and 31st December 2006: Lugo, Segovia, Talavera de la Reina, Mallorca and Almeria (total denominator, 1,440,997 inhabitants; minimum denominator per area, 100,000 inhabitants); 2) source of multiple and complementary data: hospital records (minimum basic data set, discharge abstracts), emergency and primary care records for the area with diagnostic codes 430-39 and 674.0 (International Classification of Diseases-9), population-based mortality records; 3) standardised definitions: diagnostic categorisation (MONICA-World Health Organisation, 1987), pathological classification (ischaemia, haemorrhagic), topography and aetiology; 4) presentation of data in suitable age groups, by sex and overall; 5) pilot study and analysis of inter-observer agreement among researchers.
With this design, the Iberictus study satisfies the methodological criteria as an 'ideal' study of the incidence of acute cerebrovascular diseases proposed by Malgrem, Sudlow and Warlow, and represents a unique opportunity to further our knowledge of the epidemiology of strokes in our country.
