COVID-19 Surveillance Based on Smart Wearable Device

This is a prospective cohort study. 200 subjects aged 18～75y with asymptomatic, mild, general-type COVID-19 will be recruited. The physiological parameters of wearable devices, including heart rate, sleep, blood oxygen saturation, electrocardiogram and exercise records, will be continuously collected from the day of admission / isolation to 14 days after discharge or out of quarantine. The Department of Respiratory and Critical Care of Peking University First Hospital is responsible for this research. All clinical data of patients during hospitalization will be collected including demographic characteristics, onset time, visit time, hospitalization time, symptoms, physical examination, laboratory examination, imaging characteristics, disease severity, treatment and outcome. Primary outcome is the deterioration of disease, the correlation analysis between the change of wearable device physiological parameters and the deterioration of disease determined by the traditional disease evaluation system will be used to find it whether can early alert deterioration of COVID-19.

The study protocol has been approved by the Peking University First Hospital Institutional Review Board (IRB) (2020-055). Any protocol modifications will be submitted for the IRB review and approval.
