Functioning issues in inpatients affected by COVID-19-related moderate pulmonary impairment: a real-practice observational study

Objective To investigate the correlations between clinical, functional, and radiological outcomes in inpatients with coronavirus disease 2019 (COVID-19). Methods In this observational study, we recruited inpatients affected by moderate COVID-19 disease. The clinical evaluation comprised the Cumulative Illness Rating Scale (CIRS), numerical rating scale (NRS), modified Rankin scale (mRS), and the modified Borg dyspnea scale (mBDS). Respiratory involvement was assessed with computed tomography (CT) and graded with a CT-severity score (CT-SS). We retrospectively assessed functioning using the International Classification of Functioning, Disability and Health (ICF) codes of the Clinical Functioning Information Tool (ClinFIT) COVID-19 in the acute phase. Correlation analysis was performed 1) between clinical, instrumental, and functional parameters and 2) between ICF categories. Results The data showed statistically significant moderate correlations between CT-SS and the following categories: b152 emotional functions and b440 respiratory functions. Conclusion This is the first study to use the ICF framework in people with a moderate form of COVID-19 in the acute phase. Considering the correlations between some ICF categories and radiological findings, our results support the use of the ClinFIT COVID-19 for a comprehensive assessment of COVID-19 patients.

Automated summary

This study investigated correlations between clinical, functional, and radiological outcomes in inpatients with moderate COVID-19, using the ICF framework. Significant moderate correlations were found between CT-SS and emotional functions as well as respiratory functions. The study supports the use of ClinFIT COVID-19 for comprehensive assessment of COVID-19 patients.
