The Post-COVID-19 Functional Status Scale in moderate and severe COVID-19 infections in a tertiary referral hospital in Indonesia: a retrospective study

Background & objective: Coronavirus disease 2019 (COVID-19) is known to have caused respiratory function derangement that can affect changes in the body's physiological conditions even after the active phase of infection is over. This study aimed to overview the Post-COVID-19 Functional Status (PCFS) scale at the 3rd and 6th months after treatment of moderate to severe COVID-19 infections in our tertiary referral hospital. Methodology: A descriptive observational study was conducted for confirmed COVID-19 patients with moderate to severe symptoms treated in Hasan Sadikin Hospital from June-August of 2021 by following them at third- and sixth- month post-infection and their PCFS was recorded. A total of 153 patients were enrolled in the study. Results: Eighty subjects (52.3%) were male, and 91 subjects (59.4%) had an average body mass index. Thirty-seven (24.2%) patients were diagnosed with severe symptoms, and 116 (75.8%) were diagnosed with moderate symptoms. In their third month post-infection, 30.7% of patients were on a scale of 0, 32.7% on a scale of 1, 20.9% on a scale of 2, 12.4% on a scale of 3, and 3.3% on a scale of 4. In their sixth month post-infection, 81.7% of patients were on a scale of 0, 15% on a scale of 1, and 3.3% on a scale of 3. Conclusion: The assessment of post-COVID-19 functional status has a significant role in understanding the pathophysiology and recovery process of the disease. The patients are recommended to have medical check-ups regarding organ function to determine the impact of COVID-19 and advised to undergo medical rehabilitation to return to their initial functional status.
