Outcome Measures

Primary Outcomes (1)

  • Presence of respiratory sequelae

    The presence of respiratory sequelae will be assessed by low dose thoracic tomodensitometry

    6 months after hospital discharge

Secondary Outcomes (31)

  • Presence of respiratory sequelae on low dose thoracic tomodensitometry

    3 months after hospital discharge

  • Forced vital capacity (FVC, %)

    6 months after hospital discharge

  • Forced vital capacity (FVC, %)

    3 months after hospital discharge

  • Forced expiratory volume in 1 second (FEV1, %)

    6 months after hospital discharge

  • Forced expiratory volume in 1 second (FEV1, %)

    3 months after hospital discharge

  • +26 more secondary outcomes

Study Population

Patients who have been hospitalized for severe pneumonia due to SARS-CoV-2 infection will be seen in consultation at approximately 3 and 6 months after hospital discharge, as per standard practice.

You may qualify if:

  • Age ≥ 18 years old
  • SARS-CoV-2 infection proven by RT-PCR and/or retrospective serology and/or a COVID-19 syndrome with evocative chest CT scan
  • Hospitalized for severe pneumonia due to SARS-CoV-2 infection requiring oxygen supply

You may not qualify if:

  • Not hospitalized for a severe COVID-19 infection
  • Absence of respiratory symptoms at V1 (3 months after hospital discharge), defined as: absence of residual exertional dyspnea and persistent pulmonary infiltrates on follow-up chest radiography at 1 month (if available), transcutaneous oxyhemoglobin saturation \>94% and normal pulmonary auscultation
  • Patient with pre-existing chronic lung disease prior to the first episode of COVID-19: chronic obstructive pulmonary disease confirmed by respiratory function testing with a forced expiratory volume in one second (FEV1) \< 50% and/or a diffusing capacity for carbon monoxide (DLCO) \< 60%, fibrotic lung disease or chronic respiratory failure (on long-term oxygen therapy)
  • Opposition to participation in the study
  • Patient under legal protection
  • Patient not affiliated to/beneficiary of a social security scheme
