Conclusion
This study is one of the first studies comparing the long-term outcomes
of patients with COVID-19 who were admitted to ICU and medical wards. A
number of COVID-19 survivors could not fully recover within 6 months of
hospital discharge. Unresolved CT findings, impaired PFT, and decreased
exercise capacity might be persistent in ICU patients even after 6
months. COVID-19 survivors need to be followed up on and be supported by
psychotherapeutic approaches if necessary.
