Hypothesis: Hospital presentation for acute stroke may have been delayed during COVID-19. We hypothesize that stroke patients with mild symptoms (NIHSS <= 5) were more likely to present in a delayed fashion during the early days of the pandemic. Methods: Get with The Guidelines Stroke registry was used to identify stroke patients that presented between January 1 and August 31, 2020 to the University Hospital in San Antonio, Texas. The cohort was stratified by date of presentation (before COVID: Jan 1 - Mar 15; during COVID: Mar 16 - Aug 31) and presenting NIHSS (<=5 versus >5). We then analyzed by the thrombolytic exclusion criteria delay to arrival and the time interval of stroke symptoms discovery to hospital presentation. Subgroup analysis included age, sex, and ethnicity; race was excluded due to 90% Caucasian cohort. Results: A total of 294 subjects were included of which 115 were before and 179 were during COVID. There were no significant differences in the demographics for these two time periods, although a trend for greater male presentation was seen during COVID (Table 1). After both groups were dichotomized by NIHSS <=5, stroke symptoms discovery to hospital arrival and delay to arrival (Table 2) were not significantly different across subgroups. Conclusions: Regardless of NIHSS, a significant time delay in acute stroke presentation to our hospital was not seen when comparing before and during COVID. Although our study included a large Hispanic population, the cohort was primarily Caucasian; and therefore, the results have limited application. Whether men were more likely than women to present with stroke during COVID is unclear but warrants further study with a larger sample size.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
