Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has rapidly spread worldwide. COVID-19 is highly contagious and can result in acute respiratory distress, multiple organ failure, or death in severe cases (Huang et al., 2020a, Wang et al., 2020, Yang et al., 2020, Zhang et al., 2020). The reported mortality rate of COVID-19 is lower than that of severe acute respiratory syndrome (SARS) (Donnelly et al., 2003), or Middle East respiratory syndrome (MERS) (Ahmed, 2017). However, the number of patients needing urgent critical care is remarkably larger than previous outbreaks of SARS or MERS, which could lead to a critical shortage of intensive care unit (ICU) beds and specialized medical and nursing personnel, and, consequently, result in the collapse of local health care systems. Thus, timely and appropriate dynamic monitoring and treatment for non-ICU inpatients is urgent and necessary to reduce the risk of patients becoming critically ill and requiring ICU care.
