Abstract
Background
The aim of this study was to compare the outcome of coronavirus disease 2019 (COVID-19) in hospitalised patients with chronic obstructive pulmonary disease (COPD) with the outcome in matched COVID-19 patients without COPD.
Methods
Sixty-three COPD patients hospitalised for acute COVID-19 from March through August 2020 were retrospectively identified and 63 hospitalised COVID-19 patients without COPD were selected and matched for age, gender and month of hospital admission.
Results
COPD patients had a higher rate of comorbidities, especially cardiovascular disease, and a trend towards a higher 30-day mortality than control patients (35% vs. 22%). In the COPD group, high Charlson comorbidity index (p = 0.03) and previous cerebrovascular disease (p = 0.04) were associated with 30-day mortality in univariate analysis. Inhaled corticosteroids maintenance therapy was not associated with lower mortality.
Conclusion
COPD patients hospitalised for acute COVID-19 disease had significantly more comorbidities and a high risk of severe outcome and death within 30 days. Comorbidity, especially cardiovascular diseases, was associated with mortality among COPD patients.
