Abstract
Introduction: The coronavirus disease 2019 (COVID-19) pandemic has changed the medical use of stroke patients. This study evaluated the health-seeking behavior of stroke patients and changes in stroke care services at the time of three domestic COVID-19 outbreaks in Korea using the Korean Stroke Registry (KSR) data. Methods: We reviewed data from patients with acute stroke and transient ischemic attack (TIA) from Jan 2019 to May 2021. There were three domestic COVID-19 outbreaks (1st: Feb to Mar 2020, 2nd Aug to Sep 2020, 3rd Nov 2020 to Jan 2021). Outcomes included patient characteristics, times from stroke onset to hospital arrival, and in-hospital stroke pathways. Results: The study included 34,271 patients who visited hospitals that contribute to the KSR. In the first outbreak, in Daegu city (the main epicenter), the number of patients decreased by two-thirds compared to the pre-COVID period, and the number of TIA patients was particularly decreased (9.97% to 2.91%). Unlike other regions, the median onset-to-door time increased significantly in the epicenter (361 min vs. 526.5 min, p=0.016), and longer times were common for patients with mild symptoms and who were in their 60s or 70s. The median onset-to-door time increased in the epicenter during the second outbreak, but it was not statistically significant. At the third outbreak, the median onset-to-door time was reduced even in the epicenter compared to the previous one. The number of patients decreased with each outbreak compared to the previous one, but the decrease gradually became smaller. Conclusions: Korean stroke patients in a COVID-19 outbreak region showed clear changes in health-seeking behaviors and showed a pattern of adaptation to the COVID-19 environment. There is a need for continued attention to an appropriate triage system and public education on the importance of early treatment during the COVID-19 pandemic.
