Effect of Pulmonary Rehabilitation Program on Post Hospitalization Severe COVID- 19 Patients

Overview

COVID-19 infection was discovered to be the major global cause of a serious respiratory illness toward the end of 2019. The majority of COVID-19 patients experience mild disease, while about 14% go on to have severe disease and 6% end up in critical condition. An evidence-based standard of therapy called pulmonary rehabilitation includes exercise training, education, and behavior modification to help people with lung illness feel better physically and mentally. The aim of the study to evaluate the effect of pulmonary rehabilitation program on severe post covid19 patients (post hospitalization) regarding pulmonary function tests and dyspnea score.

SARS CoV-2 infection has caused substantial death, morbidity, and unprecedented strain on the world's healthcare systems . When the illness is minor, it typically takes two weeks from the onset of symptoms till recovery, and when it is severe or critical, it may take three to six weeks. It should be mentioned that approximately 75% to 80% of hospitalized patients will remain there for more than 21 days . After the virus is defeated, COVID-19 can have serious aftereffects on the patient, with bilateral pneumonia. As a result, physiotherapy is essential in this pandemic and will play a major role in helping many patients' health. A 20-30% reduction in pulmonary capacity has already been reported in recent studies . Although pulmonary rehabilitation has been suggested following severe COVID-19, there is a lack of data showing effectiveness on recovery of physical and psychosocial parameters in severe COVID-19 patients following hospitalization. The aim of the study is to evaluate the effect of pulmonary rehabilitation program on severe post covid19 patients (post hospitalization) regarding pulmonary function tests and dyspnea score. 50 patients were enrolled in the study post hospitalization due to severe COVID 19 infection. Dyspnea score, Spirometry and 6minute walk test were performed upon discharge. Pulmonary rehabilitation program was performed. Follow up assessment of the same parameters was done 6 weeks after the program. These results were compared with another 50 patients who were admitted in hospital due to severe COVID 19 infection but no pulmonary rehabilitation program was performed to them after hospitalization.
