Trends in the seeking of emergency service for ischemic stroke and its risk factors during the COVID-19 pandemic, a study from Taiwan

ABSTRACT

Background & Objectives: COVID-19 may influence the health seeking behavior of acute ischemic stroke patients. This study aimed to determine the characteristics of the patients who visited the emergency room in a centre designated for stroke care in Taiwan. Methods: This was a retrospective database-based study comparing the severity of ischemic stroke, intracerebral hemorrhage (ICH), and risk factors of patients seen between 2019 and 2020 in the National Taiwan University Hospital Yunlin Branch. Patients with or without thrombolysis therapy were analysed. Results: The median NIHSS of ischemic stroke patients were lower in 2019 than in 2020 (p = 0.015). The difference was seen in non-thrombolysis patients (2019 3[1-6] vs. 4 [2-7.5], p = 0.012) but not in thrombolysis patients. The frequency of minor stroke was higher in 2019 (45.1%) than in 2020 (37.9%, p = 0.038). The discharge mRS was lower overall (p = 0.004) and in non-thrombolysis patients (0.003), but not in thrombolysis patients in 2019. As for the ICH patients, the severity of ICH score (p = 0.021) and discharge mRS (p = 0.001) were also lower in 2019. The frequencies of risk factors of stroke were higher in 2019 than in 2020, including smoking (24% vs. 18.2%, p = 0.046), alcohol (11.9% vs. 7.5%, p = 0.039), hypertension (72.9% vs. 66.2%, p = 0.039), history of stroke (16.5% vs. 11.6%, p = 0.047), and atrial fibrillation (11.9% vs. 7.5%, p = 0.039). Conclusions: This study in Taiwan revealed a decline in the willingness to seek emergency services under the influence of COVID-19 among patients with lower stroke severity, especially those with more risk factors.
