Effects of pulmonary rehabilitation in survivors of severe acute respiratory syndrome coronavirus 2. Role of vaccination.

Abstract

Survivors of severe COVID-19 requiring hospital admission may suffer from short- and long-term sequelae, including disability and reduced physical performance. Vaccination and pulmonary rehabilitation (PR) are effective tools against COVID-19 effects. While the beneficial effect of each of these treatments is known, there are no data about their combined effect. In people admitted to PR hospitals after severe COVID-19 disease, we retrospectively analyzed whether PR outcome might be influenced by vaccination status. Ninety-six individuals were studied (46 vaccinated, 50 unvaccinated). Unvaccinated individuals were younger and less comorbid than vaccinated ones and had needed more intensive care support during the previous hospitalization. Measures of disability and physical performance did not differ between groups at the beginning and at the end of the PR program. However, each group showed a statistically significant improvement in all outcome measures (6-minute walking test, short physical performance battery, Barthel Index). We conclude that vaccination status does not influence the outcome of in-patient PR programs for survivors of severe COVID-19.
