Retrospective cohort study

Medical records

101

Based on the clinical types, the patients were divided into a progression group and an improvement group. The definition of the progression group: clinically advanced types; patients admitted to ICU; death during hospitalization. The improvement group: the clinical types remained unchanged or changed to a lighter type, and patients were discharged from the hospital.

The study population included 101 hospitalized patients with laboratory-confirmed COVID-19, and 44 (43.6%) were men. The median age was 50.9± 20.1 years, and 27 patients were aged >=65years (26.7%). Among the 101 patients, there were 4 patients with the mild type (4.0%), 75 patients with the common type (74.3%), 13 patients with the severe type (12.9%), and nine patients with the critically ill type (8.9%) at admission.
