Insights
During the COVID-19 pandemic, emergency departments saw fewer acute ischemic stroke diagnoses. This study investigates why stroke patients, particularly in Texas, may have delayed seeking care for critical neurological symptoms.
Area of Science:
- Neurology
- Public Health
- Infectious Diseases
Background:
- The COVID-19 pandemic has been associated with a high rate of cerebrovascular complications.
- Despite this, reports indicate a decrease in new ischemic stroke diagnoses during the pandemic.
- Reduced emergency department (ED) visits are attributed to patient avoidance of potential SARS-CoV-2 exposure.
Purpose of the Study:
- To investigate the observed decrease in acute ischemic stroke diagnoses during the COVID-19 pandemic.
- To analyze stroke patient volumes in central and south Texas following shelter-at-home orders.
- To understand the impact of reduced face-to-face encounters on stroke symptom recognition and care-seeking.
Main Methods:
- Review of existing literature on cerebrovascular complications and COVID-19.
- Analysis of patient admission, treatment, and discharge data for acute stroke in Texas regions.
- Examination of stroke warning sign recognition in the context of social distancing and isolation.
Main Results:
- A significant decrease in acute ischemic stroke patient volumes is suspected in Texas EDs post-shelter-at-home orders.
- Patients may be delaying care for stroke symptoms due to fear of SARS-CoV-2 infection.
- Limited social interaction may lead to delayed recognition of stroke symptoms by family or friends.
Conclusions:
- The pandemic has likely led to a reduction in diagnosed ischemic strokes, not necessarily a true decrease in incidence.
- Patient education on recognizing stroke warning signs is crucial during periods of isolation.
- Further analysis is needed to understand the full impact on stroke care in diverse populations like those in San Antonio and Austin.
Abstract:
Despite the evidence suggesting a high rate of cerebrovascular complications in patients with SARS-CoV-2, reports have indicated decreasing rates of new ischemic stroke diagnoses during the COVID-19 pandemic. The observed decrease in emergency department (ED) visits is unsurprising during this major crisis, as patients are likely to prioritize avoiding exposure to SARS-CoV-2 over addressing what they may perceive as mild symptoms of headache, lethargy, difficulty speaking, and numbness. In the central and south Texas regions where we practice, we suspect that patient admission, treatment, and discharge volumes for acute stroke treatment have decreased significantly since COVID-19-related shelter-at-home orders were issued. Symptoms of stroke are frequently noticed by a family member, friend, or community member before they are recognized by the patients themselves, and these symptoms may be going unnoticed due to limited face-to-face encounters. This possibility emphasizes the importance of patient education regarding stroke warning signs and symptoms during the current period of isolation and social-distancing. The south Texas population, already saddled with above-average rates of cardiovascular and cerebrovascular disease, has a higher stroke mortality rate compared to Texas and U.S. averages; however, the number of patients presenting to EDs with acute ischemic stroke diagnoses is lower than average. In our viewpoint, we aim to present the relative literature to date and outline our ongoing analyses of the highly affected and diverse stroke populations in San Antonio and Austin, Texas, to answer a simple question: where did all our stroke patients go?
