Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

This is study is comprised of three approaches. First, the investigators will conduct a retrospective cohort study to determine factors associated with COVID-19 severity and complications and understand COVID-19 outcomes, including all-cause mortality, post-discharge events, and impacts of rehabilitation services (third aim). The second aim is a mixed-method study and follows COVID-19 patients with repeated surveys to determine patient-reported functional outcomes, health recovery, and rehabilitation needs after COVID-19. The investigators will recruit patients and their informal caregivers for interviews to assess their function and rehabilitation needs.
