Stroke Patients' Management During COVID-19 Pandemic: Results from the Sun4Patients Web-Based Registry

Covid-19 pandemic has influenced stroke care in different ways. Recent reports demonstrated a sharp decline in acute stroke admissions worldwide. Even for patients presented to dedicated healthcare services, management at the acute phase may be sub-optimal. On the other hand, Greece has been praised for the early initiation of restriction measures which were associated with a 'milder' surge of SARS-CoV-2 infection. Methods Data derived from a prospective cohort multicenter registry. The study population consisted of first-ever acute stroke patients, hemorrhagic or ischemic, admitted within 48 hours of symptom onset in seven national healthcare system (NHS) and University hospitals in Greece. Two different time periods have been considered, defined as "before Covid-19" (15/12/2019-15/02/2020) and "during Covid-19" (16/02/2020-15/04-2020) era. Statistical comparisons on acute stroke admission characteristics between the two different time periods have been performed. Results This exploratory analysis of 112 consecutive patients showed a reduction of acute stroke admissions by 40during Covid-19 period. No significant differences were observed regarding stroke severity, risk factor profile and baseline characteristics for patients admitted before and during Covid-19 pandemic period. There is a significant delay between symptom onset to CT scan during Covid-19 era compared to the period before pandemic reached Greece (p=0.03). Conclusions The rate of acute stroke admissions has been reduced by 40% during Covid-19 pandemic. Further research is needed to clarify whether the reduction in stroke volume is actual or not and identifying the reasons underlying the paradox.
