Three-month functional outcomes following endovascular thrombectomy during the first wave of the COVID-19 pandemic: a Canadian single-center cohort study

BackgroundThe COVID-19 pandemic has disrupted acute stroke care logistics, including delays in hyperacute management and decreased monitoring following endovascular therapy (EVT). We aimed to assess the impact of the pandemic on 90-day functional outcome among patients treated with EVT.MethodsThis is an observational cohort study including all patients evaluated for an acute stroke between March 30, 2020 and September 30, 2020 (pandemic cohort) and 2019 (reference cohort) in a high-volume Canadian academic stroke center. We collected baseline characteristics, acute reperfusion treatment and management metrics. For EVT-treated patients, we assessed the modified Rankin score (mRS) at 90 days. We evaluated the impact of the pandemic on a 90-day favourable functional status (defined as mRS 0–2) and death using multivariable logistic regressions.ResultsAmong 383 and 339 patients included in the pandemic and reference cohorts, baseline characteristics were similar. Delays from symptom onset to evaluation and in-house treatment were longer during the early first wave, but returned to reference values in the subsequent months. Among the 127 and 136 EVT-treated patients in each respective cohort, favourable 90-day outcome occurred in 53/99 (53%) vs 52/109 (48%, p=0.40), whereas 22/99 (22%) and 28/109 (26%, p=0.56) patients died. In multivariable regressions, the pandemic period was not associated with 90-day favourable functional status (aOR 1.27, 95% CI 0.60 to 2.56) or death (aOR 0.74, 95% CI 0.33 to 1.63).ConclusionIn this single-center cohort study conducted in a Canadian pandemic epicenter, the first 6 months of the COVID-19 pandemic did not impact 90-day functional outcomes or death among EVT-treated patients.

The Impact

Introduction: The COVID-19 pandemic has strained the healthcare systems across the world but its impact on acute stroke care is just being elucidated. We hypothesized a major global impact of COVID-19 not only on stroke volumes but also on thrombectomy practice. Methods: A 19-item questionnaire survey aimed to identify the changes in stroke volumes and treatment practices seen during COVID-19 pandemic was designed using Qualtrics software. It was sent to stroke and neuro-interventional physicians around the world who are part of the executive committee of a global coalition, Mission Thrombectomy 2020 (MT2020) between April 5 th to May 15 th , 2020. Results: There were 113 responses across 25 countries. Globally there was a median 33% decrease in stroke admissions and a 25% decrease in mechanical thrombectomy (MT) procedures during COVID-19 pandemic compared to immediately preceding months (Figure 1A-B). This overall median decrease was despite a median increase in stroke volume in 4 European countries which diverted all stroke patients to only a few selected centers during the pandemic. The intubation policy during the pandemic for patients undergoing MT was highly variable across participating centers: 44% preferred intubating all patients, including 25% centers that changed their policy to preferred-intubation (PI) vs 27% centers that switched to preferred-conscious-sedation (PCS). There was no significant difference in rate of COVID-19 infection between PI vs PCS (p=0.6) or if intubation policy was changed in either direction (p=1). Low-volume (<10 stroke/month) compared with high-volume stroke centers (>20 strokes/month) are less likely to have neurointerventional suite specific written personal protective equipment protocols (74% vs 88%) and if present, these centers are more likely to report them to be inadequate (58% vs 92%). Conclusion: Our data provides a comprehensive snapshot of the impact on acute stroke care observed worldwide during the 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: Limited access to stroke specialist expertise produces disparities in inpatient stroke treatment. The impact of telestroke on the remote delivery of guideline-based inpatient stroke care is yet to be comprehensively studied. The TELECAST trial (NCT03672890) prospectively examined the impact of a 24-7 telestroke specialist service dedicated to inpatient acute stroke care spanning admission to discharge. Methods: AHA stroke guidelines were used to derive outcome metrics in the following acute stroke inpatient care categories: diagnostic stroke evaluation (DSE), secondary stroke prevention (SSP), health screening and evaluation (HSE), and stroke education (SE). Adherence to AHA guidelines for stroke inpatients pre-telestroke (July 1, 2016-June 30, 2018) and post-telestroke intervention (July 1, 2018-June 30, 2019) were studied. The primary outcome was a composite score of all guideline-based stroke care. Secondary outcomes consisted of subcategory composite scores in DSE, SSP, HSE, and SE. Chi-squared tests were utilized to assess primary and secondary outcomes. Statistical analysis was performed using STATA 15.0. Results: Following institution of a comprehensive inpatient telestroke service, overall adherence to guideline-based metrics improved (composite score: 85% vs 94%, p<0.01) as did adherence to DSE guidelines (subgroup score: 90 vs 95%, p<0.01). SSP, HSE, and SE subgroup scores were not significantly different. See Table 1. Conclusion: The implementation of a 24-7 inpatient telestroke service improved adherence to AHA guidelines for inpatient acute stroke care. Dedicated inpatient telestroke specialist coverage may improve inpatient stroke care and reduce stroke recurrence in hospitals without access to stroke specialists.

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.

Iv Tpa

Background: The Cleveland Clinic Health System (CCHS) consists of a large tertiary care center and 10 regional hospitals. It is organized both clinically and administratively into multispecialty organ based Institutes rather than departments. The CCHS re-introduced a regional initiative to standardize stroke care in 2008. Medina Hospital is a 118-bed community hospital in rural North-eastern Ohio, where there is a high stroke burden and previously minimal IV tPA use. Medina Hospital joined the CCHS Stroke Network in November 2009. Hypothesis: We hypothesized that after joining the formally organized stroke CCHS system of care, the proportion of stroke patients receiving IV tPA and the timeliness of administration of acute thrombolytic therapy would both significantly increase. Methods: Data was analyzed from our prospective participation in the Get with the Guidelines-Stroke and the Ohio Coverdell Stroke Registries. Baseline data regarding quality, outcomes and stroke performance measures were reviewed. CCHS initially supported acute stroke care in early 2010 with a telemedicine cart and then introduced 24/7 emergency, on-site, CCHS neurologist, acute stroke call coverage in late 2010. Standardized CCHS stroke care pathways and order sets were also introduced in 2010. The proportion of stroke patients treated with IV tPA in 2010 and 2011 (post- joining CCHS) was compared to 2009 (2-sided Fisher’s exact test), and door-to-needle times were compared from 2010 to 2011 (unpaired t-test). Results: IV tPA treatment utilization increased from 0/69 patients (0%) in 2009 to 9/67 patients (11.8%) in 2010 [exact p=.0033] and 11/46 (19.3%) in the first 7 months of 2011 [exact p=.0001]. Door-to-needle times improved from a mean of 81.4 (95%CI 66.4 to 96.4) minutes in 2010 to 61.7 (95% CI 52.7 to 70.8) minutes in 2011 (p=.0158). Conclusions: Participation in an organized formal collaborative regional hospital stroke treatment network resulted in dramatic improvements from zero IV tPA utilization to greatly exceeding the national benchmark averages for both percentage treatment with IV tPA and door-to-needle time in a rural area where patients previously had minimal access to acute stroke expertise.
