Purpose: The purpose of this study was to analyse the possible differences, especially those regarding mortality, between patients hospitalized for community-acquired pneumonia (CAP) with and without chronic obstructive pulmonary disease (COPD), and the risk factors related to mortality in the COPD group.
Methods: 710 patients with CAP were included in a prospective multicenter observational study. 244 of the patients had COPD confirmed by spirometry.
