Characteristics and Outcomes of Stroke Patients with Concurrent SARS-CoV-2 Infection from March 1, 2020 to February 28, 2021: An Analysis from the N3C Database

Studies have shown that patients with ischemic stroke (IS) and concurrent COVID-19 have increased stroke severity. These analyses were limited by use of prepandemic era controls or by use of a sample from the early pandemic when stroke care delivery was affected by lockdown. Data on the severity of hemorrhagic stroke (HS) in patients with COVID-19 are sparse.
To test the association of SARS-CoV-2 infection with increased stroke severity in individuals with ischemic and hemorrhagic stroke during the first year of the COVID-19 pandemic in the US.
Using the National Institute of Health (NIH) National COVID Cohort Collaborative (N3C) database, we identified patients diagnosed with stroke between Mar 1, 2020 - Feb 28, 2021. Hospitalized stroke patients with concurrent COVID-19 (stroke within 3 months after or one week prior to positive SARS-CoV-2 PCR or AG lab test) were matched to all other hospitalized stroke patients in a 1:3 ratio. Nearest neighbor matching with a caliper of 0.25 was used for most clinical and demographic factors; exact matching for race/ethnicity and site. Within our matched sample, we used Poisson regression to calculate stroke severity incident rate ratio (IRR).
Our query identified 10394 patients hospitalized with IS with NIHSS scores upon admission (802 with concurrent COVID-19 and 9592 without) and 2138 patients hospitalized with HS with admission NIHSS scores (181 with concurrent COVID-19 and 1957 without). Average NIHSS was greater in concurrent groups with both IS and HS (11.1 vs 7.68, p<0.001 and 15.7 vs 11.7, p<0.001 respectively). Propensity matched analysis demonstrated that stroke patients with concurrent COVID-19 had increased NIHSS (IS: IRR=1.4, 95% CI:1.3-1.5, p<0.001; HS: IRR=1.3, 95% CI:1.2-1.5, p<0.001).
This analysis suggests that the association between increased stroke severity and COVID-19 remained as stroke care utilization normalized. Further work will center on the interaction between COVID-19 illness severity and stroke severity.
