Stroke; a journal of cerebral circulation

The efficiency of prehospital care chain response and the adequacy of hospital resources are challenged amid the coronavirus disease 2019 (COVID-19) outbreak, with suspected consequences for patients with ischemic stroke eligible for mechanical thrombectomy (MT). ⋯ Our study showed a significant decrease in patients treated with MTs during the first stages of the COVID epidemic in France and alarming indicators of lengthened care delays. These findings prompt immediate consideration of local and regional stroke networks preparedness in the varying contexts of COVID-19 pandemic evolution.

Trends in Active Cigarette Smoking Among Stroke Survivors in the United States, 1999 to 2018.
Background and Purpose- Patients who continue to smoke after a stroke face a higher risk of recurrent stroke. While several effective drugs for smoking cessation became available over the past 2 decades, whether active smoking has decreased among stroke survivors is unknown. We, therefore, evaluated trends in active smoking among stroke survivors during this period. ⋯ In contrast, there was no decrease in smoking among stroke survivors in NHANES (odds ratio, 1.00 [95% CI, 0.93-1.07]) or BRFSS (odds ratio, 0.99 [95% CI, 0.98-1.004]). Results were consistent in secondary analysis using biochemical ascertainment of active smoking in NHANES and in sensitivity analyses accounting for potential demographic changes in stroke epidemiology. Conclusions- In contrast to the general population, the prevalence of active smoking among stroke survivors has not decreased during the past 2 decades.

Background and Purpose- Hyperacute assessment and management of patients with stroke, termed code stroke, is a time-sensitive and high-stakes clinical scenario. In the context of the current coronavirus disease 2019 (COVID-19) pandemic caused by the SARS-CoV-2 virus, the ability to deliver timely and efficacious care must be balanced with the risk of infectious exposure to the clinical team. Furthermore, rapid and effective stroke care remains paramount to achieve maximal functional recovery for those needing admission and to triage care appropriately for those who may be presenting with neurological symptoms but have an alternative diagnosis. ⋯ We outline the specifics of personal protective equipment use and considerations thereof including aspects of crisis resource management impacting team role designation and human performance factors during a protected code stroke. Conclusions- We introduce the concept of a protected code stroke during a pandemic, as in the case of COVID-19, and provide a framework for key considerations including screening, personal protective equipment, and crisis resource management. These considerations and suggested algorithms can be utilized and adapted for local practice.

Multicenter Study
Regional Variation in Transient Ischemic Attack and Minor Stroke in Alberta Emergency Departments.
Background and Purpose- Multiple studies have shown the 90-day risk of stroke following an emergency department (ED) diagnosis of transient ischemic attack (TIA) or minor stroke is significant, with the greatest risk of recurrence being within the first 24 to 48 hours following initial symptom onset. This study explored regional differences in ED disposition, neuroimaging, and subsequent 90-day stroke risk of patients diagnosed with TIA or minor stroke in Alberta. Methods- We used administrative databases to identify ED visits, neuroimaging, and 90-day return visits for TIA or minor stroke in Alberta from April 2011 to March 2016 among adults ≥20 years of age and stratified them based on regions of presentation (Edmonton, Calgary, or nonmajor urban). ⋯ All 3 regions had a similar number of ED visits for TIA/minor stroke; however, on index ED visit, Calgary had a higher proportion of computed tomographic angiography imaging (48.8%; P<0.0001) compared with Edmonton (6.7%) and nonmajor urban region (5.7%) and higher proportion of discharged patients (83%; P<0.0001) compared with Edmonton (77.7%) and nonmajor urban region (73.5%). The risk of admission for stroke within 90 days of discharge after index ED visit for TIA/minor stroke in Calgary (3.4%) was lower than Edmonton (4.5%) and the nonmajor urban region (4.6%; P=0.002). Conclusions- This study demonstrates regional variation in computed tomographic angiography for neurovascular imaging of patients presenting to the ED for TIA/minor stroke and a possible association with frequency of index visit admission and 90-day readmission for the same problem.
