Changes in respiratory, physical, and mental conditions in moderate and severe COVID-19 cases at our convalescent rehabilitation ward.

Abstract

This study clarified the changes in respiratory condition, and physical and mental functions pertaining to them, of patients with the coronavirus disease 2019 ("COVID-19") who were admitted to our convalescent rehabilitation ward. It also examined the conditions remaining after the disease (long-COVID). We focused on 16 moderate and severe patients with COVID-19 who were transferred to our convalescent rehabilitation ward and discharged home between March and September 2021. We evaluated the patients' respiratory, physical, and mental conditions at the time of admission, four weeks after admission, and at the time of discharge. We confirmed an improvement in the shortness of breath in those with respiratory conditions, and a significant improvement in the walking distance related to physical function before the time of discharge, but anxiety and depression remained. Patients with moderate to severe COVID-19 can be discharged home after convalescent rehabilitation. Despite improved dyspnea and walking distance, the patients tend to have incomplete recovery, including physical deconditioning, mood disorders, and other long-COVID conditions at discharge.
