Lesson from COVID-19—Adapting Respiratory Rehabilitation Through Early Multidisciplinary Care: An Opinion Paper from Retrospective Data

The COVID-19 pandemic significantly challenged healthcare systems worldwide, highlighting the critical role of early and multidisciplinary rehabilitation interventions. There remains uncertainty about whether these rehabilitation principles developed in response to COVID-19 can be effectively generalized to chronic respiratory diseases. This opinion paper evaluates retrospective data from early stages of the COVID-19 pandemic to propose a comprehensive early multidisciplinary rehabilitation model, potentially applicable across various chronic respiratory conditions. We retrospectively analyzed data from 62 COVID-19 patients hospitalized at the University Hospital of Messina, Italy, between March and June 2020. The patients underwent structured multidisciplinary rehabilitation sessions initiated upon achieving clinical stability. Functional improvements were assessed weekly using the Barthel Index (BI). Significant correlations were observed between initial BI scores and functional improvements at discharge (<i>p</i> < 0.001) and between functional gains and the number of rehabilitation sessions administered (<i>p</i> = 0.025). Early physiatric evaluation significantly enhanced functional recovery (<i>p</i> = 0.036). Early structured multidisciplinary rehabilitation during acute hospitalization demonstrated clear benefits in COVID-19 patients, indicating potential for broad applicability in chronic respiratory disease management. Systematic implementation could improve clinical outcomes, reduce healthcare resource utilization, and enhance patients' quality of life.
