Maintenance of Acute Stroke Care Service During the COVID-19 Pandemic Lockdown

Background and Purpose: Timely reperfusion is an important goal in treatment of eligible patients with acute ischemic stroke. However, during the coronavirus disease 2019 (COVID-19) pandemic, prehospital and in-hospital emergency procedures faced unprecedented challenges, which might have caused a decline in the number of acute reperfusion therapy applied and led to a worsening of key quality measures for this treatment during lockdown. Methods: This prospective multicenter cohort study used data from the TRISP (Thrombolysis in Ischemic Stroke Patients) registry of patients with acute ischemic stroke treated with reperfusion therapies, that is, intravenous thrombolysis or endovascular therapy. We compared prehospital and in-hospital time-based performance measures (stroke-onset-to-admission, admission-to-treatment, admission-to-image, and image-to-treatment time) during the first 6 weeks after announcement of lockdown (lockdown period) with the same period in 2019 (reference period). Secondary outcomes included stroke severity (National Institutes of Health Stroke Scale) after 24 hours and occurrence of symptomatic intracranial hemorrhage (following the ECASS [European-Australasian Acute Stroke Study]-II criteria). Results: Across 20 stroke centers, 540 patients were treated with intravenous thrombolysis/endovascular therapy during lockdown period compared with 578 patients during reference period (−7% [95% CI, 5%–9%]). Performance measures did not change significantly during the lockdown period (2020/2019 minutes median: onset-to-admission 133/145; admission-to-treatment 51/48). Same was true for admission-to-image (20/19) and image-to-treatment (31/30) time in patients with available time of first image (n=871, 77.9%). Median National Institutes of Health Stroke Scale on admission (2020/2019: 11/11) and after 24 hours (2020/2019: 6/5) and percentage of symptomatic intracranial hemorrhage (2020/2019: 6.2/5.7) did not differ significantly between both periods. Conclusions: The COVID-19 pandemic lockdown resulted in a mild decline in the number of patients with stroke treated with acute reperfusion therapies. More importantly, the solid stability of key quality performance measures between the 2020 and 2019 period may indicate resilience of acute stroke care service during the lockdown, at least in well-established European stroke centers.

Introduction: Vascular imaging is increasingly used for diagnosis of arterial occlusions in acute ischemic stroke. Hypothesis:We hypothesized that time intervals using a CTA based acute ischemic stroke protocol are not increased when compared to an earlier non-CTA based protocol. Methods: We evaluated a database of consecutive patients admitted to a Brazilian tertiary hospital with acute ischemic stroke from February 2009 to March 2014 and reviewed our stroke quality measures data to determine if the time required to obtain CTA prolonged door-to-neuroimaging, door to radiology report and door-to-needle times. Patients were categorized into: Group 1 (February 2009 to October 2013) (Non-contrast CT Scan based acute stroke protocol) and Group 2 (November 2013 to August 2014) (CTA based acute stroke protocol). Time intervals were compared between the two groups.Results: We evaluated 415 consecutive patients, 20 of whom (4.8%) had a CTA in the acute phase (Group 2). Patients in groups 1 and 2 had similar onset-to-door times (1.86 [0.75-3.58] versus 2.75 hours [1.0-8.49], p=0.09); door to neuroimaging times (27.6 [18.6-46.8] versus 37.8 minutes [23.4-46.2], p=0.28 ) and door to radiology report intervals (39 [27-60.6] versus 53.4 minutes[35.4-61.2], p=0.09). The frequency of treatment with recanalization therapies ( either intravenous thrombolysis or endovascular procedures) was similar between groups 1 (30%) and 2 (21%), p=0.33, as well as door to needle times (p=0.09). Conclusions: CTA based acute stroke care does not significantly delay time to neuroimaging or thrombolysis in routine clinical practice.

Introduction: We analyzed whether the coronavirus disease 2019 (COVID-19) crisis affected acute stroke care in our center during the first 2 months of lockdown in Spain. Methods: This is a single-center, retrospective study. We collected demographic, clinical, and radiological data; time course; and treatment of patients meeting the stroke unit admission criteria from March 14 to May 14, 2020 (COVID-19 period group). Data were compared with the same period in 2019 (pre-COVID-19 period group). Results: 195 patients were analyzed; 83 in the COVID-19 period group, resulting in a 26% decline of acute strokes and transient ischemic attacks (TIAs) admitted to our center compared with the previous year (p = 0.038). Ten patients (12%) tested positive for PCR SARS-CoV-2. The proportion of patients aged 65 years and over was lower in the COVID-19 period group (53 vs. 68.8%, p = 0.025). During the pandemic period, analyzed patients were more frequently smokers (27.7 vs. 10.7%, p = 0.002) and had less frequently history of prior stroke (13.3 vs. 25%, p = 0.043) or atrial fibrillation (9.6 vs. 25%, p = 0.006). ASPECTS score was lower (9 [7–10] vs. 10 [8–10], p = 0.032), NIHSS score was slightly higher (5 [2–14] vs. 4 [2–8], p = 0.122), onset-to-door time was higher (304 [93–760] vs. 197 [91.25–645] min, p = 0.104), and a lower proportion arrived within 4.5 h from onset of symptoms (43.4 vs. 58%, p = 0.043) during the COVID-19 period. There were no differences between proportion of patients receiving recanalization treatment (intravenous thrombolysis and/or mechanical thrombectomy) and in-hospital delays. Conclusion: We observed a reduction in the number of acute strokes and TIAs admitted during the COVID-19 period. This drop affected especially elderly patients, and despite a delay in their arrival to the emergency department, the proportion of patients treated with recanalization therapies was preserved.

Variation In Care

Introduction In the nationwide Dutch Acute Stroke Audit (DASA), consecutive patients with acute ischaemic stroke (AIS) and intracranial haemorrhage (ICH) are prospectively registered. Acute stroke care is a rapidly evolving field in which intravenous thrombolysis (IVT) and intra-arterial thrombectomy (IAT) play a crucial role in increasing odds of favourable outcome. The DASA can be used to assess the variation in care between hospitals and develop ‘best practice’ in acute stroke care. Patients and methods: We describe the initiation and design of the DASA as well as the results from 2015 and 2016. Results In 2015 and 2016, 55,854 patients with AIS and 7727 patients with ICH were registered in the DASA. Treatment with IVT was administered to 10,637 patients (with an increase of 1.3% in 2016) and 1740 patients underwent IAT (with an increase of 1% in 2016). Median door-to-needle time for IVT and median door-to-groin time for IAT have decreased from 27 to 25 min and 66 to 64 min, respectively. Mortality during admission was 4.9% in patients with AIS, whereas 26% of patients with ICH died. Modified Rankin Scale score at three months was registered in 49% of AIS patients and 45% of ICH patients. Discussion During the nationwide DASA, time to treatment is reduced for IVT as well as IAT. With the rapidly evolving treatment of acute stroke care, the DASA can be used to monitor the quality provided on patient- and hospital level. Conclusion Increasing completeness of registration of the outcome, in combination with adjustment for patient-related factors, is necessary to define and further improve the quality of the acute stroke care.

Suspected Stroke

Background: Sex differences are encountered in many aspects of ischemic stroke, including risk factors, presenting symptoms, stroke mechanism, acute interventions and functional outcomes. As telestroke services continue to expand, many patients utilize telestroke for the evaluation and treatment of suspected stroke symptoms. To date, the existence of such differences between sexes has not been identified in the patient population having utilized telestroke for acute stroke care. Methods: A retrospective observational study of the experience of a single teleneurology practice serving 340 hospitals from April 2018 to June 2020 was performed. Patients seen in the emergency department (ED) with a diagnosis of suspected stroke were included. Data from the acute stroke encounter was reported through the current medical record platform. Results: Within the queried period, there were 11,454 male and 11,794 female patients identified as having received ED telestroke evaluation for suspected acute stroke. Males were younger than females (67 vs 70, P <0.01). Males had higher rates of prior stroke, hypertension, diabetes, hyperlipidemia, and coronary disease than females ( P <0.01), while females had higher rates of atrial fibrillation ( P =0.03) and TIA ( P <0.01). Rates of antiplatelet and anticoagulants were higher in males ( P <0.01) than females. There were no differences in time to ED presentation, time to request consult or make a thrombolysis decision, or length of consult. Females had higher stroke severity ( P <0.01) and door-to-needle times ( P <0.01), but lower alteplase rates ( P =0.02) compared to males. Conclusion: This review of a national heterogeneous telestroke patient population is indicative of sex differences in multiple aspects of acute ischemic stroke, most notably in thrombolysis delivered via telestroke. Further investigation into the etiology of such differences is warranted, as well as a survey of functional outcomes. As telemedicine continues to expand in the era of the COVID-19 pandemic, it is imperative that the reasons behind this disparity are investigated.

Global Epidemiology

Purpose of the ReviewTo provide an up-to-date review of the incidence of stroke and large vessel occlusion (LVO) around the globe, as well as the eligibility and access to IV thrombolysis (IVT) and mechanical thrombectomy (MT) worldwide.Recent FindingsRandomized clinical trials have established MT with or without IVT as the usual care for patients with LVO stroke for up to 24 hours from symptom onset. Eligibility for IVT has extended beyond 4.5 hours based on permissible imaging criteria. With these advances in the last 5 years, there has been a notable increase in the population of patients eligible for acute stroke interventions. However, access to acute stroke care and utilization of MT or IVT is lagging in these patients.SummaryStroke is the second leading cause of both disability and death worldwide, with the highest burden of the disease shared by low- and middle-income countries. In 2016, there were 13.7 million new incident strokes globally; ≈87% of these were ischemic strokes and by conservative estimation about 10%–20% of these account for LVO. Fewer than 5% of patients with acute ischemic stroke received IVT globally in the eligible therapeutic time window and fewer than 100,000 MTs were performed worldwide in 2016. This highlights the large gap among eligible patients and the low utilization rates of these advances across the globe. Multiple global initiatives are underway to investigate interventions to improve systems of care and bridge this gap.

Background and Purpose: Idarucizumab achieves instant reversal of anticoagulation and enables intravenous thrombolysis (IVT) in dabigatran-treated acute ischemic stroke (AIS) patients. AIS in dabigatran-treated patients is a rare event, therefore the experience is limited. A review of all published cases was performed to evaluate the safety and effectiveness of this therapeutic strategy.Methods: We searched PubMed and Scopus for all published cases of IVT after reversal with idarucizumab in dabigatran-treated AIS patients. The outcomes were safety assessed by hemorhagic transformation (HT), symptomatic intracranial hemorrhage (SICH) and death, and efficacy assessed by National Institutes of Health Stroke Scale (NIHSS) reduction.Results: We identified 251 AIS patients (39,9% females) with an average age of 74 years. HT, SICH, and death were reported in 19 (7.6%), 9 (3.6%), and 21 (8.4%) patients, respectively. Patients experiencing HT presented with more severe strokes (median NIHSS on admission: 21 vs. 8, p < 0.001; OR: 1.12, 95% CI: 1.05–1.20). After IVT there was a significant NIHSS reduction of 6 points (IQR:3–10, p < 0.001) post-stroke and linear regression revealed a correlation of admission NIHSS to NIHSS reduction (p < 0.001).Conclusions: In this systematic review of all published cases of IVT in dabigatran-treated AIS patients after reversal with idarucizumab the rates of HT, SICH and mortality, as well as NIHSS reduction, were comparable with previous studies in non-anticoagulated patients. This provides reassuring evidence about the safety and efficacy of this therapeutic strategy.

Stroke Treatment

Background: Stroke is a major cause of morbidity and disability worldwide. However, its outcomes have improved in the last few years with advancement in acute stroke treatment, including the use of tissue plasminogen activator (t-PA) within 4.5 hours of onset, which led several international guidelines to adopt it as the standard of care. In this study, authors sought to assess the knowledge, practices, and attitudes of emergency and medicine staff in Qassim, Saudi Arabia toward acute ischemic stroke care.Methods: A quantitative observational cross-sectional study involving 148 physicians from emergency and medicine departments (only three neurologists) was conducted in three main hospitals of the Qassim region, Saudi Arabia. Information was obtained from a self-administered questionnaire. A logistic regression model was used to control for potential confounding factors.Results: Ninety-two percent of participants were aware of t-PA. Eighty-seven percent of participants thought that t-PA was an effective treatment for acute ischemic stroke. Only 20% of participants had given t-PA or participated in the use of t-PA in acute ischemic stroke. Moreover, 64% of participants believed that allowing blood pressure to remain high was the most appropriate action in the first 24 hours in acute ischemic stroke patients who presented outside the t-PA window.Conclusion: Most of the emergency and medicine staff are well informed about t-PA, but the majority of these physicians have never given t-PA or participated in the administration of t-PA to a stroke patient. The main finding here is the positive outlook among emergency and medicine physicians in Qassim toward training in acute stroke care and administering t-PA for stroke, which will positively impact patient outcomes.

PurposeThe ThRombolysis in Ischemic Stroke Patients (TRISP) collaboration aims to address clinically relevant questions about safety and outcomes of intravenous thrombolysis (IVT) and endovascular thrombectomy. The findings can provide observational information on treatment of patients derived from everyday clinical practice.ParticipantsTRISP is an open, investigator-driven collaborative research initiative of European stroke centres with expertise in treatment with revascularisation therapies and maintenance of hospital-based registries. All participating centres made a commitment to prospectively collect data on consecutive patients with stroke treated with IVT using standardised definitions of variables and outcomes, to assure accuracy and completeness of the data and to adapt their local databases to answer novel research questions.Findings to dateCurrently, TRISP comprises 18 centres and registers >10 000 IVT-treated patients. Prior TRISP projects provided evidence on the safety and functional outcome in relevant subgroups of patients who were excluded, under-represented or not specifically addressed in randomised controlled trials (ie, pre-existing disability, cervical artery dissections, stroke mimics, prior statin use), demonstrated deficits in organisation of acute stroke care (ie, IVT during non-working hours, effects of onset-to-door time on onset-to-needle time), evaluated the association between laboratory findings on outcome after IVT and served to develop risk estimation tools for prediction of haemorrhagic complications and functional outcome after IVT.Future plansFurther TRISP projects to increase knowledge of the effect and safety of revascularisation therapies in acute stroke are ongoing. TRISP welcomes participation and project proposals of further centres fulfilling the outlined requirements. In the future, TRISP will be extended to include patients undergoing endovascular thrombectomy.

Intravenous Tissue Plasminogen Activator

Background: Despite proven efficacy of intravenous tissue plasminogen activator (tPA) and endovascular thrombectomy (EVT) in acute ischemic stroke, there has been slow administration of these therapies in the real world practice. We examined the ongoing quality improvement in acute stroke care at our comprehensive stroke center. Methods: Consecutive patients with acute ischemic stroke from 2013 to 2018 were studied. Patients were managed using Code Stroke algorithm per concurrent AHA guidelines and a simple quality improvement protocol implemented in 2015. Demographics and clinical data were collected from Get-With-The-Guideline-Stroke registry and electronic medical records. Patients were divided into 3 groups per admission and implementation date of quality improvement initiatives. Quality measures, including rates of intravenous tPA and EVT, door-to-needle (DTN) time, and door-to-puncture (DTP) time, were analyzed with general mean linear regression models and Jonckheere-Terpstra test. Results: Of the 1,369 eligible patients presenting within 24 hours of symptom onset or wakeup stroke, the rate of intravenous tPA was 20%, 30% and 22%, respectively, in 2013-2014, 2015-2016, and 2017-2018. In contrast, EVT rate was 9%, 14% and 15%, respectively. Based on Jonckheere-Terpstra test, there was significant ongoing improvement in the median DTN time (57, 45, 39 minutes; p < 0.001) and DTP time (172, 130, 114 minutes; p =0.009) during the 3 time periods, with DTN time ≤ 60 and ≤45 minutes in 80% and 63% patients, respectively, in 2017-2018. Conclusions: Getting with the guidelines and simple quality improvement initiatives are associated with satisfactory rates of acute stroke therapy and ongoing improvement in door to treatment times.

Background: In-hospital and 30-day mortality, 3-month functional outcome were reported as associated with endovascular treatment (EVT) case volume per hospital, but one-year mortality was unknown. Furthermore, the hospital EVT volume threshold based on one-year mortality was not reported. We aimed to investigate whether there was a correlation between annual EVT case volume per hospital and one-year mortality and suggest volume threshold. Methods: Data from Korean national survey for assessing quality of acute stroke care were used. The survey was conducted since 2005 and the subject was patients with acute stroke who were admitted via emergency rooms within 7 days of onset at hospitals treating 10 or more stroke cases during the three (2013, 2014) or six (2016) month survey period. Ischemic stroke cases treated with EVT during the last available three assessments (2013, 2014, and 2016) were selected for the analysis. Results: A total of 1,746 ischemic stroke cases (age, 69.2 ± 12.4years; male, 56.6%) treated in 120 hospitals with EVT were analyzed. The median annual EVT case volume was 12.0 cases per hospital (interquartile range, 6.0-22.9) and the mortality at one-month, three-month, and one-year were 12.7%, 16.6%, and 23.3%, respectively. When divided into quartiles according to the annual EVT case volume, the lowest quartile group was found to have the highest one-year mortality (odds ratio [95% confidence intervals], 1.49 [1.04-2.13]), adjusted for age, sex, NIHSS, onset to arrival time. Restricted cubic splines performed on the annual EVT case volume per hospital revealed that cut-off value for the probability of one-year mortality was 15 cases per year ( p <0.02) (Figure). Conclusions: There was an association between annual EVT case volume and one-year mortality, and the volume threshold per hospital based on the one-year mortality was found to be 15 EVT cases per year.
