Chronic respiratory diseases are predictors of severe outcome in COVID-19 hospitalised patients: A nationwide study

Résumé

Background: Influenza epidemics were initially considered to be a suitable model for the COVID-19 epidemic, but there is a lack of data concerning patients with chronic respiratory diseases (CRD), who were supposed to be at risk of severe forms of COVID-19. Methods: This nationwide retrospective cohort study describes patients with prior lung disease hospitalized for COVID-19 (March-April 2020) or influenza (2018-2019 influenza outbreak). We compare the resulting pulmonary complications, need for intensive care and in-hospital mortality depending on respiratory history and virus. Results: In the 89, 530 COVID-19 cases, 16.03% had at least one CRD, which was significantly less frequently than in the 45, 819 seasonal influenza patients. Patients suffering from chronic respiratory failure, chronic obstructive pulmonary disease, asthma, cystic fibrosis and pulmonary hypertension were underrepresented, contrary to those with lung cancer, sleep apnea, emphysema, and interstitial pulmonary diseases (ILD). COVID-19 patients with CRD developed significantly more ventilator-associated pneumonia and pulmonary embolism than influenza patients. They needed intensive care significantly more often and had a higher mortality rate (except for asthma) when compared to patients with COVID-19 but without CRD, or patients with influenza. Conclusion: Patients with prior respiratory diseases were globally less likely to be hospitalized for COVID-19 than for influenza but were at higher risk of developing severe COVID-19 and had a higher mortality rate compared to influenza patients and patients without a history of respiratory illness.
