Insights
The COVID-19 pandemic saw a decrease in overall stroke patients but a significant increase in Black and Hispanic individuals presenting with strokes. Widespread testing is recommended to explore potential links between SARS-CoV-2 infection and stroke disparities.
Area of Science:
- Neurology
- Public Health
- Epidemiology
Background:
- The COVID-19 pandemic has strained healthcare systems globally.
- Lockdowns reduced hospital visits for non-respiratory conditions like strokes.
- Existing racial disparities in COVID-19 infection rates prompted an investigation into stroke patient demographics.
Purpose of the Study:
- To determine if racial disparities observed in COVID-19 cases extended to patients presenting with strokes during the pandemic.
- To compare stroke presentation rates across different racial groups before and during the COVID-19 pandemic.
Main Methods:
- Utilized the Get with the Guidelines National Stroke Database for ischemic stroke, TIA, SAH, and IPH diagnoses.
- Analyzed data from February-May 2020 (pandemic period) and compared it to the same period in 2019 (control).
- Assessed data from a single hospital, California hospitals, Pacific State hospitals, Western Region hospitals, and all U.S. hospitals, categorizing patients by race.
Main Results:
- A general decrease in total stroke patient numbers was observed across all assessed regions.
- A statistically significant increase in stroke presentations was noted among Black and Hispanic populations in California, Pacific, Western, and national U.S. hospital cohorts.
- Specific months showed significant increases for Hispanic patients (Feb-Apr) and Black patients (Apr) in various regional analyses when comparing 2020 to 2019.
Conclusions:
- The COVID-19 pandemic disproportionately impacted certain racial groups, including those presenting with strokes.
- A correlation between increased stroke incidence in specific racial populations and the pandemic is suggested.
- The study highlights the need for widespread SARS-CoV-2 testing to investigate potential links between viral infection, racial disparities, and stroke presentation.
Abstract:
Introduction The global coronavirus disease 2019 (COVID-19) pandemic has had deleterious effects on our healthcare system. Lockdown measures have decreased the number of patients presenting to the hospital for non-respiratory illnesses, such as strokes. Moreover, there appears to be a racial disparity among those afflicted with the virus. We sought to assess whether this disparity also existed for patients presenting with strokes. Methods The Get with the Guidelines National Stroke Database was reviewed to assess patients presenting with a final diagnosis of ischemic stroke, transient ischemic attack (TIA), subarachnoid hemorrhage (SAH), or spontaneous/nontraumatic intraparenchymal hemorrhage (IPH). The period of February - May 2020 was chosen given the surge of patients affected with the virus and national shutdowns. Data from this same time during 2019 was used as the control population. Our hospital numbers and four additional regions were assessed (California hospitals, Pacific State hospitals, Western Region hospitals, and all hospitals in the United States). Patients were categorized by race (White, Black/African American, Asian, Native American, Hispanic) in each cohort. The primary endpoint of this study is to compare whether there was a significant difference in the proportion of patients in each reported racial category presenting with stroke during the COVID-19 pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Results A downward trend in total number of patients was noted in all five regional cohorts assessed. A statistically significant increase in the number of Black and Hispanic patients presenting with strokes was noted in California, Pacific hospitals, Western hospitals, and all hospitals in the United States during various months studied comparing 2020 to 2019. A statistically significant increase in the Hispanic population was noted in February and March in all California hospitals (p=0.005 and 0.02, respectively) and Pacific Coast hospitals (p=0.005 and 0.039, respectively). The Western region and all national hospitals noted a significant increase in strokes in the Hispanic population in April (p=0.039 and 0.023, respectively). A statistically significant increase of strokes in the Black population was noted in April in Pacific hospitals, Western region hospitals, and all national hospitals (p=0.039, 0.03, and 0.03, respectively). Conclusion The COVID-19 pandemic has adversely affected certain racial groups more than others. A similar increase is noted in patients presenting with strokes in these specific racial populations. Moreover, lack of testing for the SARS-CoV-2 virus may be missing a possible link between racial disparity for patients infected with the virus and patients presenting with stroke. The authors advocate for widespread testing for all patients to further assess this correlation.
