ABSTRACT
BACKGROUND: COVID-19 has caused a global shift in healthcare-seeking behaviour; however, presentation rates with serious conditions, such as stroke in low COVID-19-prevalence cities, has received less attention. AIMS: To determine if there was a significant reduction in stroke admissions, delivery of acute reperfusion therapies, or increased delays to presentation during the first wave of the COVID-19 pandemic. METHODS: A multicentre, retrospective, observational cohort study was performed across three tertiary hospitals in Brisbane, Australia. Cases were identified using ICD-10 codes and then individually reviewed for eligibility using prespecified inclusion and exclusion criteria. All metrics were compared over 3 months from 1 March to 31 May 2020 with two corresponding 3-month periods in 2018 and 2019. RESULTS: There was a mean of 2.15 (95% CI 1.87-2.48) stroke admissions per day in the examined pandemic months compared with 2.13 (95% CI 1.85-2.45) and 2.26 (95% CI 1.97-2.59) in March to May 2018 and 2019 respectively, with no significant difference found (P = 0.81). There was also no difference in rates of intravenous thrombolysis (P = 0.82), endovascular thrombectomy (P = 0.93) and time from last known well to presentation (P = 0.54). Conversely, daily emergency department presentations (including non-stroke presentations) significantly reduced (P < 0.0001). CONCLUSIONS: During the early months of the COVID-19 pandemic there was no significant reduction in stroke presentations, use of acute reperfusion therapies or delays to presentation, despite a reduction in ED presentations for any cause. Our results differ from the global experience, with possible explanations, including differences in public health messaging and healthcare infrastructure.
