Accuracy of Acoustic Evaluation of Swallowing as a Diagnostic Method of Dysphagia in Individuals Affected by Stroke: Preliminary Analysis.

After a stroke, more than half of the patients have some kind of disability, and dysphagia is frequently found. Cervical auscultation by Doppler sonar is an innovative technique with gain of credibility in the clinical evaluation of swallowing. To verify the diagnostic accuracy of Doppler sonar along with the DeglutiSom® software as an auxiliary method in the evaluation of oropharyngeal dysphagia in patients after stroke. The research is a cross-sectional, uncontrolled, blind, quantitative study with systematic random sampling. Patients from inpatient and outpatient units of a reference hospital with a stroke care unit were concomitantly submitted to both Doppler sonar and Fiberoptic Endoscopic Evaluation of Swallowing (FEES®). Seventy-three audio files collected from 26 patients through Doppler sonar were analyzed using DeglutiSom® software and confronted with the FEES® report, regarding three food consistencies offered to them during the exam. The study showed that the Doppler sonar correctly identified, among all the analyzed files, those that actually presented tracheal aspiration as well as it effectively identified patients who did not aspirate. The Youden index of 0.91 corroborates this information, showing a promising accuracy in detecting tracheal aspiration in the studied sample. The study evaluates the diagnostic accuracy of Doppler sonar, showing that it can be used as a valuable tool in the diagnosis of tracheal aspiration in patients after stroke. It is important to emphasize that the identification of residue by this method requires further studies. Also, larger sample size and more than one blind evaluator should be considered in future researches to increase the reliability of the proposed method.

Quality of Care and One-Year Outcomes in Patients with Diabetes Hospitalised for Stroke or TIA: A Linked Registry Study

ObjectivesTo evaluate key quality indicators for acute care and one-year outcomes following acute ischaemic stroke (IS), intracerebral haemorrhage (ICH), or transient ischaemic attack (TIA) by diabetes status. Materials and MethodsObservational cohort study (2009-2013) using linked data from the Australian Stroke Clinical Registry and hospital records. Diabetes was ascertained through review of hospital records. Multilevel regression models were used to evaluate the association between diabetes and outcomes, including discharge destination, and mortality and hospital readmissions within one-year of stroke/TIA. ResultsAmong 14,132 patients (median age 76 years, 46% female), 22% had diabetes. Compared to patients without diabetes, those with diabetes were equally likely to receive stroke unit care, but were more often discharged on antihypertensive agents (79% vs. 68%) or with a care plan (50% vs. 47%). In patients with TIA, although 86% returned directly home after acute care, those with diabetes more often had a different discharge destination than those without diabetes. Diabetes was associated with greater all-cause mortality (hazard ratio 1.13, 95% CI 1.04-1.23) in patients with IS/ICH; and with both greater all-cause (1.81, CI 1.35-2.43) and CVD mortality (1.75, CI 1.06-2.91) in patients with TIA. Similarly, diabetes was associated with greater rates of all-cause readmission in both patients with IS/ICH and TIA. ConclusionsDespite good adherence to best care standards for acute stroke/TIA, patients with comorbid diabetes had worse outcomes at one-year than those without comorbid diabetes. Associations of diabetes with poorer outcomes were more pronounced in patients with TIA than those with IS/ICH.

Prise en charge de l’infarctus cérébral à la phase initiale

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

A full year of the COVID-19 pandemic with two infection waves and its impact on ischemic stroke patient care in Germany.

Background and purposeMany countries worldwide, including Germany, reported that the first wave of the coronavirus disease 2019 (COVID‐19) pandemic in early 2020 influenced the care of acute ischemic stroke (AIS) patients, but data are lacking for further pandemic wave periods.MethodsWe conducted a nationwide, retrospective, cross‐sectional study of all hospitalized patients with the main diagnosis of AIS in 2019 and 2020. Primary outcomes were the number of hospitalizations for AIS, the application of stroke unit care, intravenous thrombolysis (IVT), and mechanical thrombectomy (MT), as well as the in‐hospital mortality during the different pandemic periods in 2020 compared to the corresponding periods in 2019. Secondarily, we analyzed differences in outcomes between patients with and without concurrent COVID‐19.ResultsWe included 429,841 cases with AIS, of which 1268 had concurrent COVID‐19. Hospitalizations for AIS declined during both pandemic wave periods in 2020 (first wave: −10.9%, second wave: −4.6%). MT rates were consistently higher throughout 2020 compared to 2019, whereas the IVT rate dropped during the second wave period (16.0% vs. 17.0%, p < 0.001). AIS patients with concurrent COVID‐19 frequently received recanalization treatments, with an overall MT rate of 8.4% and IVT rate of 15.9%. The in‐hospital mortality was high (22.8% vs. 7.5% in noninfected AIS patients, p < 0.001).ConclusionsThese findings demonstrate a smaller decline in hospitalizations for AIS in the more severe second wave of the COVID‐19 pandemic. AIS patients with and without concurrent COVID‐19 who did seek acute care continued to receive recanalization treatments in Germany.

Preconditioning by Preceding Ischemic Cerebrovascular Events

BackgroundEmerging yet contrasting evidence from animal and human studies associates ischemic preconditioning with improvement of subsequent stroke severity, although long‐term outcome remains unclear. The purpose of this study was to analyze how preceding cerebral ischemic events influence subsequent stroke severity and outcome.Methods and ResultsData for this retrospective cohort study were extracted from ASTRAL (Acute Stroke Registry and Analysis of Lausanne). This registry includes a sample of all consecutive patients with acute ischemic strokes admitted to the stroke unit and/or intensive care unit of the Lausanne University Hospital, Switzerland. We investigated associations between preceding ischemic events (transient ischemic attacks or ischemic strokes) and the impact on subsequent stroke severity and clinical improvement within 24 hours, measured through National Institute of Health Stroke Scale, as well as 3‐month outcome, determined through a shift in the modified Rankin Scale. Of 3530 consecutive patients with ischemic stroke (43% women, median age 73 years), 1001 (28%) had ≥1 preceding cerebral ischemic events (45% transient ischemic attack, 55% ischemic stroke; 31% multiple events). After adjusting for multiple prehospital, clinical, and laboratory confounders, admission stroke severity was significantly lower in patients preconditioned through a preceding ischemic event, but 24‐hour improvement was not significant and 3‐month outcome was unfavorable.ConclusionsPreceding ischemic events were independently associated with a significant reduction in subsequent stroke severity but worsened long‐term clinical outcome. These results, if confirmed by future randomized studies, may help design neuroprotective strategies. The unfavorable effect on stroke outcome is probably a consequence of the cumulative disability burden after multiple ischemic events.

Delayed Comprehensive Stroke Unit Care Attributable to the Evolution of Infection Protection Measures across Two Consecutive Waves of the COVID-19 Pandemic.

We aimed to assess how evidence-based stroke care changed over the two waves of the COVID-19 pandemic. We analyzed acute stroke patients admitted to a tertiary care hospital in Germany during the first (2 March 2020–9 June 2020) and second (23 September 2020–31 December 2020, 100 days each) infection waves. Stroke care performance indicators were compared among waves. A 25.2% decline of acute stroke admissions was noted during the second (n = 249) compared with the first (n = 333) wave of the pandemic. Patients were more frequently tested SARS-CoV-2 positive during the second than the first wave (11 (4.4%) vs. 0; p < 0.001). There were no differences in rates of reperfusion therapies (37% vs. 36.5%; p = 1.0) or treatment process times (p > 0.05). However, stroke unit access was more frequently delayed (17 (6.8%) vs. 5 (1.5%); p = 0.001), and hospitalization until inpatient rehabilitation was longer (20 (1, 27) vs. 12 (8, 17) days; p < 0.0001) during the second compared with the first pandemic wave. Clinical severity, stroke etiology, appropriate secondary prevention medication, and discharge disposition were comparable among both waves. Infection control measures may adversely affect access to stroke unit care and extend hospitalization, while performance indicators of hyperacute stroke care seem to be untainted.

Evaluation of Clinical Presentation and Associated Comorbid Conditions in Patients with Spontaneous Intracerebral Hemorrhage in a Tertiary Care Hospital in Bangladesh

Spontaneous intracerebral hemorrhage (ICH) has remained the least treatable form of stroke despite recent improvements in medical treatment. Treatment usually supportive and medical such as ventilatory support, blood pressure reduction, osmotherapy, fever control, seizure control and nutritional support and treatment of co morbidconditions. This study was carried out to see demographic variability, clinical presentation, causes and outcome of spontaneous intracerebral hemorrhage. Methods and materials: This was a cross sectional observational prospective in study on 50 spontaneous ICH patients admitted in Medicine department of Khulna Medical College Hospital from November 2020 to April, 2021. Result: The study showed that spontaneous ICH was most common in between 41-70 years. Their age frequency were 14 (28%) in 41-50 years, 15 (30%)in 51- 60 years, 12 (24%) in 61-70 years, 5 (10%) in 71- 80 years and 4 (8%) in more than 81 years age group. Among the patients, 64% (32) were male and 36% (18) were female. No of smoker male was 25(50%) and female was 1(2%) and no of nonsmoker male was 7(14%) and female was 17(34%). Headache was present in 56% (28) and absent in 44% (22) of patients. Vomiting was present in 54% (27) and was absent in 46% (23)of patients.Seizure was present in 16% (8) and was absent in 54% (42) of patients. Diabetes mellitus was present in 22% (11) of patients and absent in 78% (39) patients. Range of blood pressure –&lt;140/90 in 24%(12), Systolic BP:140-159/Diastolic BP:90-99 (mm Hg) in 10%(5), Systolic BP:160-179/Diastolic BP:100-109 (mm Hg) in 22%(11),Systolic BP:180 or more/Diastolic BP:110 or more (mm Hg) in 44%(22) patients. Dyslipidemia was present in 30% (15) &amp; absent in 70% (35) patients. Glasgow Coma Scale Score was 8 or less in 42% (21) and 9 or more in 58% (29) patients. Conclusion: Spontaneous ICH is common in Indian subcontinent. As death occur due to ICH itself, associated co morbidities or due to complications, management in stroke care unit, High dependency unit and Intensive care unit is required.

Demographic Variables, Co morbidities and Clinical Presentation of Spontaneous Intracerebral Hemorrhage (ICH) in a tertiary Care Hospital in Bangladesh: A Cross Sectional Study

A Cluster of Coronavirus Disease 2019 (COVID-19) Cases on an Inpatient Hospital Unit Involving Multiple Modes of Transmission

Background: The Ohio State University Wexner Medical Center identified a cluster of coronavirus disease 2019 (COVID-19) cases on an inpatient geriatric stroke care unit involving both patients and staff. The period of suspected severe acute respiratory coronavirus virus 2 (SARS-CoV-2) transmission and exposure on the unit was December 20, 2020, to January 1, 2021, with some patients and staff developing symptoms and testing positive within the 14 days thereafter. Methods: An epidemiologic investigation was conducted via chart review, staff interviews, and contact tracing to identify potential patient and staff linkages. All staff who worked on the unit were offered testing regardless of the presence of symptoms as well as all patients admitted during the outbreak period. Results: In total, 6 patients likely acquired COVID-19 in the hospital (HCA). An additional 6 patients admitted to the unit during the outbreak period subsequently tested positive but had other possible exposures outside the hospital (Fig. 1). One patient failed to undergo COVID-19 testing on admission but tested positive early in the cluster and is suspected to have contributed to patient to employee transmission. Moreover, 32 employees who worked on the unit in some capacity during this period tested positive, many of whom became symptomatic during their shifts. In addition, 18 employees elected for asymptomatic testing with 3 testing positive; these were included in the total. Some staff also identified potential community exposures. Additionally, staff reported an employee who was working while symptomatic with inconsistent mask use (index employee) early in the outbreak period. The index employee likely contributed to employee transmission but had no direct patient contact. Our epidemiologic investigation ultimately identified 12 employees felt to be linked to transmission based on significant, direct patient care provided to the patients within the outbreak period (Fig. 1). In addition, 3 employees had an exposure outside the hospital indicating likely community transmission. Conclusions: Transmission was felt to be multidirectional and included employee-to-employee, employee-to-patient, and patient-to-employee transmission in the setting of widespread community transmission. Interventions to stop transmission included widespread staff testing, staff auditing regarding temperature and symptom monitoring, and re-education on infection prevention practices. Particular focus was placed on appropriate PPE use including masking and eye protection, hand hygiene, and cleaning and disinfection practices throughout the unit. SARS-CoV-2 admission testing and limited visitation remain important strategies to minimize transmission in the hospital.Funding: NoDisclosures: None

Post-operative Right Ventricular Failure After Cardiac Surgery: A Cohort Study.

Introduction: Right ventricular failure (RVF) after cardiac surgery is an important risk factor for morbidity and mortality. Its diagnosis is challenging, and thus, its incidence and predictors are not well-established. We investigated the incidence, complications, and variables associated with clinically relevant post-operative RVF.Methods: We included all patients who underwent cardiac surgery with cardiopulmonary bypass between 2016 and 2019 in a cardiac surgery center with standardized diagnostic and therapeutic management of RVF. RVF was considered only if clinically relevant: associated with hemodynamic instability requiring catecholamine support and inhaled nitric oxide relayed by sildenafil.Results: Overall, 3,826 patients were included, of whom, 110 (2.9%) developed post-operative RVF. Mortality was not different among patients who developed post-operative RVF, compared with the rest of the cohort (1.8 vs. 0.7%, p = 0.17). Using a composite outcome that combined death, reintubation, stroke, and prolonged intensive care unit stay (more than 14 days) yielded an incidence of 6.6%, and RVF was associated with this composite outcome with an odds ratio of 3.6 (2.2–5.8), p < 0.001. In a multivariable model, pre-operative variables independently associated with post-operative RVF were pre-operative atrial fibrillation (AF) {adjusted odds ratio (adjOR) 3.22 [95% confidence interval (95%CI) = 1.94–5.36], p < 0.001}, left ventricle ejection fraction below 50% [adjOR = 2.55 (95%CI = 1.52–4.33), p < 0.001], systolic pulmonary artery pressure above 55 mmHg [adjOR = 8.64 (95%CI = 5.27–14.1); p < 0.001], mitral valve surgery [adjOR = 2.17 CI (95%CI = 1.28–3.66), p = 0.004], and tricuspid valve surgery [adjOR = 10.33 (95%CI = 6.14–17.4), p < 0.001]. In patients who developed post-operative RVF requiring treatment, 32 (29.1%) showed RV dysfunction before surgery.Conclusion: In this cohort study, 2.9% of patients developed clinically significant post-operative RVF. Moreover, RVF was associated with severe adverse outcomes, including death, strokes, reintubation, and prolonged intensive care unit stay.

Outcome Prediction for Patients With Ischemic Stroke in Acute Care: New Three-Level Model by Eating and Bladder Functions

ObjectiveTo develop a new prediction model by combining independence in eating and bladder management functions, and to assess its utility in an acute care setting.MethodsPatients with ischemic stroke who were admitted in our acute stroke care unit (n=250) were enrolled in this study. Functional Independence Measure (FIM) scores for eating and bladder management on the initial day of rehabilitative treatment (median, 3 days) were collected as predictive variables. These scores were divided into low (<5) and high (≥5) and categorized as values 0 and 1, respectively. From the simple summation of these two-level model values, we derived a three-level model that categorized the scores as values 0, 1, and 2. The FIM-motor scores at discharge (median, 14 days) were collected as outcome measurements. The three-level model was assessed by observing the distribution patterns of the outcome FIM-motor scores and logistic regression analyses.ResultsThe median outcome FIM-motor score was 19 (interquartile range [IQR],13.8–45.3) for the value 0 category (n=14), 66.5 (IQR, 59.5–81.8) for the value 1 category (n=16), and 84 (IQR, 77–89) for the value 2 category (n=95) in the three-level model. Data fitting by logistic regression for FIM-motor scores of 41.3 and 61.4 reached 50% probability of values 1 and 2, respectively.ConclusionDespite the simplicity of the three-level model, it may be useful for predicting outcomes of patients with ischemic stroke in acute care.

Association Between Cemented vs Cementless Hemiarthroplasty and Short-Term Change of In-Hospital Mortality in Elderly Patients with Femoral Neck Fracture: A Propensity-Score Matching Analysis in a Multicenter Database

ObjectiveCemented hemiarthroplasty is recommended for the vulnerable hip fracture population because of beneficial long-term outcomes. However, the association between cemented hemiarthroplasty and short-term mortality is controversial. To increase a preparedness of potential complication after cemented hemiarthroplasty, we aimed to evaluate the trajectory of the effect of cemented hemiarthroplasty on short-term in-hospital outcomes.MethodsWe investigated in-hospital mortality and complications between cemented hemiarthroplasty and cementless hemiarthroplasty using a nationwide multicenter database from 2010 to 2016 with a propensity-score matching analysis. We analyzed in-hospital mortality from 1 to 14 days after surgery. We also investigated in-hospital complications that may associate with mortality.ResultsAfter matching of 31,322 cases, we found no significant difference in 30-day in-hospital mortality between the cemented and cementless hemiarthroplasty groups (hazard ratio, HR [95% confidence interval, CI], 1.2 [0.89–1.6], p = 0.23). However, the 1- to 10-day postoperative mortality rates were significantly higher in the cemented group and the association becomes weaker as the postoperative period increased (day 1; HR [95% CI]: 3.5 [1.6–7.68]; day 10; HR [95% CI]: 1.59 [1.07–2.37]). The incidence of stroke and intensive care unit (ICU) admission was also significantly higher in the cemented group.ConclusionCemented hemiarthroplasty was not significantly associated with an increase in overall in-hospital mortality but was significantly associated with short-term mortality from 1-day to 10-day after surgery. The incidence of stroke and ICU admission was also significantly higher in the cemented group. Surgeons should pay more attention to the risk of mortality and stroke in patients undergoing cemented hemiarthroplasty, especially in the early days of hospitalization.

Randomized Sham-Controlled Pilot Study of Neurocardiac Function in Patients With Acute Ischaemic Stroke Undergoing Heart Rate Variability Biofeedback.

Background: Neurocardiac dysfunction worsens clinical outcome and increases mortality in stroke survivors. We hypothesized that heart rate variability (HRV) biofeedback improves neurocardiac function by modulating autonomic nervous system activity after acute ischaemic stroke (AIS).Methods: We randomly allocated (1:1) 48 acute ischaemic stroke patients to receive nine sessions of HRV- or sham biofeedback over 3 days in addition to comprehensive stroke unit care. Before and after the intervention patients were evaluated for HRV via standard deviation of normal-to-normal intervals (SDNN, primary outcome), root mean square of successive differences between normal heartbeats (RMSSD), a predominantly parasympathetic measure, and for sympathetic vasomotor and sudomotor function. Severity of autonomic symptoms was assessed via survey of autonomic symptom scale total impact score (TIS) at baseline and after 3 months.Results: We included 48 patients with acute ischaemic stroke [19 females, ages 65 (4.4), median (interquartile range)]. Treatment with HRV biofeedback increased HRV post intervention [SDNN: 43.5 (79.0) ms vs. 34.1 (45.0) ms baseline, p = 0.015; RMSSD: 46.0 (140.6) ms vs. 29.1 (52.2) ms baseline, p = 0.015] and alleviated autonomic symptoms after 3 months [TIS 3.5 (8.0) vs. 7.5 (7.0) baseline, p = 0.029], which was not seen after sham biofeedback (SDNN: p = 0.63, RMSSD: p = 0.65, TIS: 0.06). There were no changes in sympathetic vasomotor and sudomotor function (p = ns).Conclusions: Adding HRV biofeedback to standard stroke unit care led to improved neurocardiac function and sustained alleviation of autonomic symptoms after acute ischaemic stroke, which was likely mediated by a predominantly parasympathetic mechanism.Clinical Trial Registration: www.ClinicalTrials.gov, identifier: NCT03865225.

Palliative care after stroke: A review.

BackgroundPalliative care is an integral aspect of stroke unit care. In 2016, the American Stroke Association published a policy statement on palliative care and stroke. Since then there has been an expansion in the literature on palliative care and stroke.AimOur aim was to narratively review research on palliative care and stroke, published since 2015.ResultsThe literature fell into three broad categories: (a) scope and scale of palliative care needs, (b) organization of palliative care for stroke, and (c) shared decision making. Most literature was observational. There was a lack of evidence about interventions that address specific palliative symptoms or improve shared decision making. Racial disparities exist in access to palliative care after stroke. There was a dearth of literature from low- and middle-income countries.ConclusionWe recommend further research, especially in low- and middle-income countries, including research to explore why racial disparities in access to palliative care exist. Randomized trials are needed to address specific palliative care needs after stroke and to understand how best to facilitate shared decision making.

Stroke Care in the United Kingdom During the COVID-19 Pandemic.

The coronavirus disease 2019 (COVID-19) pandemic has potentially caused indirect harm to patients with other conditions via reduced access to health care services. We aimed to describe the impact of the initial wave of the pandemic on admissions, care quality, and outcomes in patients with acute stroke in the United Kingdom. Registry-based cohort study of patients with acute stroke admitted to hospital in England, Wales, and Northern Ireland between October 1, 2019, and April 30, 2020, and equivalent periods in the 3 prior years. One hundred fourteen hospitals provided data for a study cohort of 184 017 patients. During the lockdown period (March 23 to April 30), there was a 12% reduction (6923 versus 7902) in the number of admissions compared with the same period in the 3 previous years. Admissions fell more for ischemic than hemorrhagic stroke, for older patients, and for patients with less severe strokes. Quality of care was preserved for all measures and in some domains improved during lockdown (direct access to stroke unit care, 1-hour brain imaging, and swallow screening). Although there was no change in the proportion of patients discharged with good outcome (modified Rankin Scale score, ≤2; 48% versus 48%), 7-day inpatient case fatality increased from 6.9% to 9.4% (P<0.001) and was 22.0% in patients with confirmed or suspected COVID-19 (adjusted rate ratio, 1.41 [1.11-1.80]). Assuming that the true incidence of acute stroke did not change markedly during the pandemic, hospital avoidance may have created a cohort of untreated stroke patients at risk of poorer outcomes or recurrent events. Unanticipated improvements in stroke care quality should be used as an opportunity for quality improvement and to learn about how to develop resilient health care systems.

Stroke-unit care for stroke patients in China: the results from Bigdata Observatory platform for Stroke of China

To assess whether stroke patients admitted to stroke units (SU) have a better short-term outcome than those treated in conventional wards (CW). A total of 20 hospitals from 16 provinces in China were initially selected in this study. Finally, 24,090 consecutive admissions in 2013-2015 treated in CW and 21,332 consecutive entries in 2017-2019 treated in SU were included. The primary endpoint of this study was the all-cause death or dependency condition three months after admission. Patients in the SU group were more likely receiving thrombolytic therapy (3.9 vs 2.1%) and intravascular treatment (1.2 and 0.7%). In-hospital death were lower in the SU group than the CW group (SU vs CW: 2.93 vs 4.58% [absolute difference, - 2.28% {95% CI, - 3.32% to - 0.93%}, odd ratio {OR}, 0.72{95% CI, 0.61 to 0.82}]. Death after discharge was also lower in the SU group than the CW (SU vs CW: 5.07 vs 6.72% [absolute difference, - 2.33% {95% CI, - 3.39% to - 0.90%}, odd ratio {OR}, 0.75{95% CI, 0.68 to 0.84}]. In addition, patients who received SU care were less likely to be dead or disabled than those patients who received CW care after adjusting for other variability (SU vs CW: 36.20 vs 44.33% [absolute difference, - 11.33% {95% CI, - 15.32% to - 7.14%}, odd ratio {OR}, 0.78{95% CI, 0.80 to 0.85}]. Among patients with stroke, admission to a designated SU was associated with modestly lower mortality at discharge, reduced probability of death, or being disabled at the end of follow-up.

Impact of the COVID-19 pandemic and a national lockdown on hospitalizations for stroke and related 30-day mortality in France: A nationwide observational study.

Background and purposeThe aim of this nationwide study was to assess the impact of the COVID‐19 pandemic on stroke hospitalization rates, patient characteristics and 30‐day case fatality rates.MethodsAll hospitalizations for stroke from January to June of each year from 2017 to 2020 were selected using International Classification of Diseases, 10th revision, codes I60 to I64 in the national hospital discharge database. Patient characteristics and management were described according to three time periods: pre‐lockdown, lockdown, and post‐lockdown. Weekly incidence rate ratios (IRRs) were computed to compare time trends in the rates of patients hospitalized for stroke as well as in‐hospital and 30‐day case fatality rates between the years 2017–2019 and 2020.ResultsIn 2020, between weeks 1 and 24, 55,308 patients were hospitalized for stroke in France. IRRs decreased by up to 30% for all age groups, sex, and stroke types during the lockdown compared to the period 2017–2019. Patients hospitalized during the second and third weeks of the lockdown had higher in‐hospital case fatality rates compared to 2017–2019. In‐hospital case fatality rates increased by almost 60% in patients aged under 65 years. Out‐of‐hospital 30‐day case fatality rates increased between weeks 11 and 15 among patients who returned home after their hospitalization. Important changes in care management were found, including fewer stroke patients admitted to resuscitation units, more admitted to stroke care units, and a shorter mean length of hospitalization.ConclusionsDuring the first weeks of the lockdown, rates of patients hospitalized for stroke fell by 30% and there were substantial increases of both in‐hospital and out‐of‐hospital 30‐day case fatality rates.

Stroke Care During the COVID-19 Pandemic: Asian Stroke Advisory Panel Consensus Statement

The COVID-19 pandemic has impacted the health system worldwide. Stroke is one of the leading causes of death and disability in the world. Asia has a diverse health system and more than two-thirds of strokes occur in this region. The Asian Stroke Advisory Panel (ASAP) conducted a survey among the member countries to explore the impact of COVID-19 on stroke care. The stroke admission numbers have fallen, as have the number of patients who received thrombolysis and mechanical thrombectomy. The stroke unit and rehabilitation beds have been reallocated for COVID-19 care. ASAP recommends emergency department screening of stroke patients for COVID-19 and protected stroke code to be activated for COVID-19 suspect stroke patients. Noncontrast computed tomography (CT), CT angiography, and CT chest are the imaging modalities of choice. All health care professionals involved in triaging, imaging, and stroke care should wear appropriate personal protective equipment. All eligible stroke patients (COVID suspect/positive/non-COVID) should receive intravenous thrombolysis/mechanical thrombectomy. Mobile stroke units and robots can be used wherever available for evaluation and triaging. All stroke patients should receive standard stroke unit care. Limited rehabilitation should be offered to patients and training of caregivers if needed. Telemedicine/telestroke should be used for rehabilitation and follow-up. The ASAP consensus statement can be adapted to suit local and national health care systems.
