Changes in Stroke Patient's Health-seeking Behavior by COVID-19 Epidemic Regions : Data from Korean Stroke Registry

Introduction The coronavirus disease 2019 (COVID-19) pandemic has led to changes in stroke patients' healthcare use. This study evaluated changes in Korean stroke patients' health-seeking behaviors and stroke care services using data from the Korean Stroke Registry (KSR). Methods We reviewed data from patients with acute stroke and transient ischemic attack (TIA) during 2019 (before COVID-19 period) and 2020 (COVID-19 period). Outcomes included patient characteristics, time from stroke onset to hospital arrival, and in-hospital stroke pathways. Subgroup analyses were performed for an epidemic region (Daegu city and Gyeongsangbuk-do region, the D-G region). Results The study included 1,792 patients from the pre-COVID-19 period and 1,555 patients from the COVID-19 period who visited hospitals that contribute to the KSR. During the COVID-19 period, the D-G region had two-thirds the number of cases (vs. the pre-CO-VID-19 period) and a significant decrease in the proportion of patients with TIA (9.97%-2.91%). Unlike other regions, the median onset-to-door time increased significantly in the D-G region (361 min vs. 526.5 min, p = 0.016), and longer onset-to-door times were common for patients with mild symptoms and who were in their 60s or 70s. The number of patients who underwent intravenous thrombolysis also decreased during the COVID-19 period, although the treatment times were not significantly different between the 2 periods. Discussion/conclusion Korean stroke patients in a CO-VID-19 epidemic region exhibited distinct changes in health-seeking behaviors. Appropriate triage system and public education regarding the importance of early treatment are needed during the COVID-19 pandemic.
