Transfusion demand in COVID‐19 patients from the Korean population: a nationwide study in South Korea

As patients infected with severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) often present coagulopathy depending on disease severity, appropriate prevention and treatment for hemodynamics control are most essential for Coronavirus disease 2019 (COVID‐19) management (Helms, et al 2020). Although several papers alarmed the decrease of blood donation in the COVID‐19 pandemic as expected (Mohammadi, et al 2020, Pagano, et al 2020), few research investigated the actual prevalence of blood transfusion requested in hospitalized COVID‐19 patients (Berzuini, et al 2020, Doyle, et al 2020), and no publication reported nationwide result until today. Here, we examined the transfusion demand in COVID‐19 patients using the Korean nationwide COVID‐19 patient database generated by the government.
