Treat COVID-19, but Not Only COVID-19: Stroke Matters as Well

Introduction: During the COVID-19 pandemic, studies reported less number of hospitalizations for acute stroke and reduction in the use of recanalization treatments. This study analyzes nationwide data on stroke admissions and management in the Czech Republic during the first wave of the COVID-19 pandemic. Methods: We compared the early COVID-19 pandemic (March–May 2020) with the pre-pandemic period (January–February 2020 and March–May 2019): (a) the National Register of Reimbursed Health Services provided volume of all admissions for subarachnoid hemorrhage (SAH), intracerebral hemorrhage (ICH), and ischemic stroke (IS), and volume of recanalization treatments (intravenous thrombolysis [IVT] and mechanical thrombectomy [MT]); (b) Registry of Stroke Care Quality provided door-to-needle time (DNT), onset-to-door time (ODT), and stroke severity at admission (National Institutes of Health Stroke Scale, NIHSS) for IS. Results: During the pandemic (March–May 2020), the peak number of COVID-19 patients treated in Czech hospitals was 39 per million. In March–May 2020 versus March–May 2019, hospital admissions decreased as follows: stroke overall by 14% (p < 0.001), IS by 14% (p < 0.001), SAH by 15% (p = 0.07), and ICH by 7% (p = 0.17). The mean age was 74 years versus 74 years (p = 0.33), and 52% versus 51% were men (p = 0.34). The volumes of IVT and MT decreased by 14% (p = 0.001) and 19% (p = 0.01), respectively. The proportions of all IS patients receiving IVT or MT remained unchanged, with, respectively, 17% versus 17% receiving IVT (p = 0.86) and 5% versus 5% receiving MT (p = 0.48). DNT and ODT were 24 versus 25 min (p = 0.58) and 168 versus 156 min (p = 0.23), respectively. NIHSS at admission did not differ (6 vs. 6; p = 0.54). Conclusion: Even with a low burden of COVID-19 during the first wave and no change in organization and logistics of stroke services, stroke admissions and volume of recanalization treatments decreased. Public health communication campaigns should encourage people to seek emergency medical care for stroke symptoms during the COVID-19 pandemic.

The Impact

Introduction: The COVID-19 pandemic resulted in significant healthcare reorganizations, potentially striking standard medical care. We investigated the impact of the COVID-19 pandemic on acute stroke care quality and clinical outcomes to detect healthcare system’s bottlenecks from a territorial point of view. Methods: Crossed-data analysis between a prospective nation-based mandatory registry of acute stroke, Emergency Medical System (EMS) records, and daily incidence of COVID-19 in Catalonia (Spain). We included all stroke code activations during the pandemic (March 15–May 2, 2020) and an immediate prepandemic period (January 26–March 14, 2020). Primary outcomes were stroke code activations and reperfusion therapies in both periods. Secondary outcomes included clinical characteristics, workflow metrics, differences across types of stroke centers, correlation analysis between weekly EMS alerts, COVID-19 cases, and workflow metrics, and impact on mortality and clinical outcome at 90 days. Results: Stroke code activations decreased by 22% and reperfusion therapies dropped by 29% during the pandemic period, with no differences in age, stroke severity, or large vessel occlusion. Calls to EMS were handled 42 min later, and time from onset to hospital arrival increased by 53 min, with significant correlations between weekly COVID-19 cases and more EMS calls (rho = 0.81), less stroke code activations (rho = −0.37), and longer prehospital delays (rho = 0.25). Telestroke centers were afflicted with higher reductions in stroke code activations, reperfusion treatments, referrals to endovascular centers, and increased delays to thrombolytics. The independent odds of death increased (OR 1.6 [1.05–2.4], p 0.03) and good functional outcome decreased (mRS ≤2 at 90 days: OR 0.6 [0.4–0.9], p 0.015) during the pandemic period. Conclusion: During the COVID-19 pandemic, Catalonia’s stroke system’s weakest points were the delay to EMS alert and a decline of stroke code activations, reperfusion treatments, and interhospital transfers, mostly at local centers. Patients suffering an acute stroke during the pandemic period had higher odds of poor functional outcome and death. The complete stroke care system’s analysis is crucial to allocate resources appropriately.

The Impact

Introduction: Stroke is a serious health problem, given it is the second leading cause of death and a major cause of disability in the European Union. Our study aimed to assess the impact of stroke care organization measures (such as the development of stroke units, implementation of a regional stroke code, and treatment with intravenous thrombolysis and mechanical thrombectomy) implemented from 1997 to 2017 on hospital admissions due to stroke and mortality attributed to stroke in the Madrid health region. Methods: Epidemiological data were obtained from the National Statistics Institute public website. We collected data on the number of patients discharged with a diagnosis of stroke, in-hospital mortality due to stroke and the number of inhabitants in the Madrid health region each year. We calculated rates of discharges and mortality due to stroke and the number of inhabitants per SU bed, and we analysed temporal trends in in-hospital mortality due to stroke using the Daniels test in 2 separate time periods (before and after 2011). Figures representing annual changes in these data from 1997 to 2017 were elaborated, marking stroke care organizational measures in the year they were implemented to visualize their temporal relation with changes in stroke statistics. Results: Hospital discharges with a diagnosis of stroke have increased from 170.3/100,000 inhabitants in 1997 to 230.23/100,000 inhabitants in 2017. However, the in-hospital mortality rate due to stroke has decreased (from 33.3 to 15.2%). A statistically significant temporal trend towards a decrease in the mortality percentage and rate was found from 1997 to 2011. Conclusions: Our study illustrates how measures such as the development of stroke units, implementation of a regional stroke code and treatment with intravenous thrombolysis coincide in time with a reduction in in-hospital mortality due to stroke.

Score Evaluation

Background: Availability of 4G cellular network and video cellphone handsets may allow mobile videophone assessment to be employed in prehospital stroke care. The California Brief Stroke Scale (CABSS) is a 4 item scale designed as a mobile videophone test to evaluate a prehospital telemedicine instrument to rate stroke severity. Potential uses include identifying patients who are likely harboring persisting large vessel occlusions and to characterize baseline deficits prior to enrollment in prehospital trials. Methods: One bedside and one remote CABSS score were independently obtained on 15 ischemic stroke patients with persistent neurologic deficits. The bedside examination was performed by a stroke neurologist. The remote examination was performed by a second stroke neurologist through mobile video phone. A CABSS score of 1 or higher (scale 0-7) was an index of global stroke deficit severity. Kappa coefficients were calculated for concordance between bedside and remote scores. Results: The median National Institutes of Health Stroke Scale score was 6 (interquartile range IQR 4-10). On average the CABSS score evaluation took 25 seconds to perform. The median video CABSS was 2, (IQR1-3) and median bedside CABSS was 3, (IQR 1-3). Based on weighted K coefficients, cortical findings (aphasia, gaze deviation/hemineglect) displayed excellent agreement κ=1 (95% CI 1.0) and non-cortical findings (facial droop, arm drift) displayed substantial agreement κ =0.7 (95% CI 0.4-1.0). There was substantial agreement between bedside and remote methods for the total CABSS κ 0.68 (95% CI 0.44-0.92). The CABSS scores obtained by bedside and remote methods were strongly correlated (r= 0.85, P<0.0001). Conclusion: Our prospective study found that mobile videocell phone evaluation using CABSS is a feasible and reliable means of examining hyperacute stroke patients in the field. A physician can rapidly perform an audiovideo examination to increase the accuracy of prehospital identification of patients harboring persisting large vessel occlusions and characterize baseline deficits prior to enrollment in prehospital clinical trials to a clinically important degree.

Background and Purpose— We evaluated the feasibility and the reliability of remote stroke severity quantification in the prehospital setting using the Unassisted TeleStroke Scale (UTSS) via a telestroke ambulance system and a fourth-generation mobile network. Methods— The technical feasibility and the reliability of the UTSS were studied in healthy volunteers mimicking 41 stroke syndromes during ambulance transportation. Results— Except for 1 issue, high-quality telestroke assessment was feasible in all scenarios. The mean examination time for the UTSS was 3.1 minutes (SD, 0.4). The UTSS showed excellent intrarater and interrater variability (ρ=0.98 and 0.97; P <0.001), as well as excellent internal consistency and rater agreement. Adequate concurrent validity can be derived from the strong correlation between the UTSS and the National Institutes of Health Stroke Scale (ρ=0.90; P <0.001). Conclusions— Remote assessment of stroke severity in fast-moving ambulances using a system dedicated to prehospital telemedicine, 4G technology, and the UTSS is feasible and reliable.

Background and Purpose: Mechanical thrombectomy helps prevent disability in patients with acute ischemic stroke involving occlusion of a large cerebral vessel. Thrombectomy requires procedural expertise and not all hospitals have the staff to perform this intervention. Few population-wide data exist regarding access to mechanical thrombectomy. Methods: We examined access to thrombectomy for ischemic stroke using discharge data from calendar years 2016 to 2018 from all nonfederal emergency departments and acute care hospitals across 11 US states encompassing 80 million residents. Facilities were classified as hubs if they performed mechanical thrombectomy, gateways if they transferred patients who ultimately underwent mechanical thrombectomy, and gaps otherwise. We used standard descriptive statistics and unadjusted logistic regression models in our primary analyses. Results: Among 205 681 patients with ischemic stroke, 100 139 (48.7% [95% CI, 48.5%–48.9%]) initially received care at a thrombectomy hub, 72 534 (35.3% [95% CI, 35.1%–35.5%]) at a thrombectomy gateway, and 33 008 (16.0% [95% CI, 15.9%–16.2%]) at a thrombectomy gap. Patients who initially received care at thrombectomy gateways were substantially less likely to ultimately undergo thrombectomy than patients who initially received care at thrombectomy hubs (odds ratio, 0.27 [95% CI, 0.25–0.28]). Rural patients had particularly limited access: 27.7% (95% CI, 26.9%–28.6%) of such patients initially received care at hubs versus 69.5% (95% CI, 69.1%–69.9%) of urban patients. For 93.8% (95% CI, 93.6%–94.0%) of patients with stroke at gateways, their initial facility was capable of delivering intravenous thrombolysis, compared with 76.3% (95% CI, 75.8%–76.7%) of patients at gaps. Our findings were unchanged in models adjusted for demographics and comorbidities and persisted across multiple sensitivity analyses, including analyses adjusting for estimated stroke severity. Conclusions: We found that a substantial proportion of patients with ischemic stroke across the United States lacked access to thrombectomy even after accounting for interhospital transfers. US systems of stroke care require further development to optimize thrombectomy access.

Stroke Registry

Background: Intravenous Thrombolysis with Recombinant Tissue Plasminogen Activator (rt-PA) availability at Chinese hospitals varies and may affect care quality for acute ischemic stroke patients. Limited research has shown whether there were differences in quality of care at China National Stroke Registry (CNSR II) hospitals based on rt-PA capability. Methods: For acute ischemic stroke patients admitted to CNSR II hospitals between 2012 and 2013, care quality at hospitals with or without Intravenous rt-PA capability was examined by evaluating conformity with performance and quality measures. The primary outcome was guideline-concordant care, defined as compliance with 10 predefined individual guideline-recommended performance metrics and composite score. A composite score was defined as the total number of interventions actually performed among eligible patients divided by the total number of recommended interventions among eligible patients. Propensity score matching was used to balance the baseline characteristics. We used cox model with shared frailty model and logistic regression with generalized estimating equation to compare the relationship between hospitals with rt-PA capability and hospitals without rt-PA on quality measures. Results: This study included 19604 acute ischemic stroke patients admitted to 219 CNSR II hospitals. Before matching, there were 7928 patients admitted to 86 (40.4%) hospitals with rt-PA capability and 11676 patients admitted to 133 (59.6%) hospitals without rt-PA capability. After matching, 7606 pairs of patients in rt-PA-capable hospitals and rt-PA-incapable hospitals were analyzed. Before matching, the composite score of guideline-concordant process of care was higher at hospitals with rt-PA capability than hospitals without rt-PA capability (74% versus 73%, P=0.0126). Hospitals with rt-PA capability were more likely to perform deep vein thrombosis prophylaxis within 48 hours of admission, dysphagia screening, assessment or receiving of rehabilitation, discharge antithrombotic, anticoagulation for atrial fibrillation and medications for lowering low-density lipoprotein (LDL) ≥100mg/dL. But hospitals with rt-PA capability were less likely to perform antithrombotic medication within 48 hours of admission and hypoglycemic therapy at discharge for patients with diabetes. After matching, differences of stroke care quality between hospitals with rt-PA capability and without rt-PA capability still exist after adjusting covariates. Conclusions: The CNSR II hospitals were associated with better performance in some of the hospitals but not all of them. The difference in conformity between rt-PA-capable hospitals and rt-PA-incapable hospitals was modest for performance measures of stroke care. However, more room for improvement still exists in key quality performance measures and further studies should be explored.

AbstractData about the coronavirus disease 2019 (COVID-19) pandemic’s collateral damage on ischemic stroke (IS) care during the second epidemic wave in Central Europe are limited. We sought to evaluate the impact of the COVID-19 outbreak on Hungarian IS care during the two epidemic waves. This retrospective observational study was based on a nationwide reimbursement database that encompasses all IS admissions and all reperfusion interventions, i.e., intravenous thrombolysis (IVT) and endovascular therapy (EVT) from 2 January 2017 to 31 December 2020 in Hungary. COVID-19 pandemic’s effect on the number of IS admissions and reperfusion interventions were analyzed using different statistics: means, medians, trends, relative rates, and linear relationships. The mean and median values of IS admissions and reperfusion interventions decreased only in some measure during the COVID-periods. However, trend analysis demonstrated a significant decline from the trends. The decline’s dynamic and amplitude have differed for each variable. In contrast to IVT, the number of IS admissions and EVTs negatively correlated with the epidemic waves’ amplitude. Besides, the decrease in the number of IS admissions was more pronounced than the decrease in the number of reperfusion interventions. Our study demonstrated a significant disruption in IS care during the COVID-19 epidemic in Hungary, in which multiple different factors might play a role. The disproportionate reduction of IS admission numbers could partially be explained by the effect of health emergency operative measures and changes in patients’ social behavior. Further studies are needed to evaluate the causes of our observations.

Background: The anterior cerebral artery (ACA) supplies many eloquent areas and can have anatomical variations making ACA strokes clinically and radiologically challenging. This study looks at the clinical and radiological features of isolated acute ACA strokes from a stroke centre in Oman. Methods: A retrospective study conducted over a 2 year period on ACA strokes presenting within 12 hours of symptom onset. TOAST classification was used for aetiology. National Institutes of Health Stroke Scale (NIHSS) and Modified Rankin Scale (mRS) were used to assess stroke severity. Fischer’s classification was used for assessing the arterial segments with CT angiogram. Heidelberg Bleeding Classification was used for haemorrhagic conversion. Results: Isolated ACA strokes constituted 25/1180 (2.1 %) of ischemic strokes. Males 15/25 (60%) Mean age was 68.4 years (Range 42 -97 years). Twenty eight percent of patients had earlier strokes. Hemiparesis (68%) was the commonest clinical presentation. Twenty percent had only lower limb weakness. Hypertension 22/25 (88%) followed by diabetes mellitus 12/25 (48%) was the commonest risk factor. The mean NIHSS was 9 (range 3 to 13). In 36% of patients there was progression of stroke. Plain CT Picked the infarct only in 6/24 (25%). Left side involvement in 18/25 (72%) Artery of Hubner was involved in 6/25 (24%); 44% had an embolic aetiology. There was no mortality and at discharge, 11/25 (44%) had mRS3 or less. Conclusions: In acute ACA infarcts a CT scan can miss the diagnosis in 74%. An embolic aetiology has to be considered in any Isolated ACA stroke and the outcome appears to be good.

Symptomatic Intracranial Hemorrhage

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: Although Mobile Stroke Treatment Units (MSTU) can reduce time to intravenous thrombolysis (IVtPA), limitations in MSTU care have not been well described. Methods: We retrospectively reviewed consecutive patients transported by MSTU to our academic comprehensive stroke center (CSC) from May 2019 to August 2020 for suspected stroke to assess for potential limitations of care. The Columbus MSTU is owned by a separate health system, but represents a collaborative venture with 3 CSCs and the Columbus Division of Fire, operating daily from 7am-7pm. Data was abstracted on demographics, clinical presentation, last known normal (LKN) time, initial National Institutes of Health Stroke Scale (NIHSS), neuroimaging, and IVtPA administration. Results: Among 93 patients transported to our CSC by MSTU, the mean age was 65 years (range, 21-93) and 61 (66%) were female. The mean initial NIHSS was 7.1 (range, 0 to 33) and 52 (55.9%) had a final diagnosis of stroke (4 hemorrhagic, 48 ischemic). IVtPA was administered in 15 (16.1%) with a mean LKN to IVtPA time of 120 minutes (range, 41 to 243). Among 15 patients treated with IVtPA, 10 received IVtPA in MSTU and 5 in CSC ED. In 7 patients who underwent thrombectomy, mean door to groin time was 57 minutes (range, 28 to 88). Among the overall group, 9 (9.7%) cases were identified with limitations in MSTU care, including 2 patients who received IVtPA by MSTU that were more than 10% off from ideal dosing (underdosed by 9mg and overdosed by 21mg), 1 warfarin-associated hemorrhage requiring intubation who did not receive reversal in MSTU but did upon arrival to CSC ED, and 5 patients who received IVtPA after arrival to CSC ED. The reasons for withholding IVtPA included inability to confirm LKN, patient declination, lack of translator, incorrect LKN, and seizure requiring intubation. The LKN to IVtPA time was significantly longer in the ED compared to MSTU (197 vs 82 minutes, p <0.0001). Conclusion: In our series of suspected stroke patients evaluated by MSTU, gaps identified within MSTU acute stroke care were related to limitations of resources and included errors in weight-based IVtPA dosing, inability to administer IVtPA, or reversal for anti-coagulation related hemorrhage. Clinicians need to be aware of potential pitfalls of MSTU evaluation.
