Clinical characteristics of Coronavirus Disease 2019 and development of a prediction model for prolonged hospital length of stay.

Background: The epidemic of Coronavirus Disease 2019 (COVID-19) has become a global health emergency, but the clinical characteristics of COVID-19 are not fully described. We aimed to describe the clinical characteristics of COVID-19 outside of Wuhan city; and to develop a multivariate model to predict the risk of prolonged length of stay in hospital (ProLOS).

Methods: The study was conducted in a tertiary care hospital in Zhejiang province from January to February 20, 2020.
