Highlights
- •Hospital admissions for CAP increased over time in patients with and without COPD.
- •In-hospital mortality decreased over time in both groups of patients.
- •There were no differences in mortality by COPD status during admissions for CAP.
Abstract
Aim
To examine trends in incidence and outcomes of community-acquired pneumonia (CAP)
hospitalizations among patients with or without COPD in Spain (2004–2013).
Methods
We used national hospital discharge data to select all hospital admissions for CAP.
Incidence was calculated overall and according to the presence or absence of COPD.
Results
We identified 901,136 hospital admissions for CAP (32.25% with COPD). Incidence of
hospitalizations of CAP increased significantly over time among patients with and
without COPD, but it was higher among people with COPD for all years analyzed. S. pneumoniae decreased over time for both groups. Time trend analyses showed significant decreases
in mortality during admission for CAP for patients with and without COPD. Factor independently
associated with higher mortality in both groups included: male sex, older age, higher
comorbidity, isolation of S. aureus or P. aeruginosa, use of mechanical ventilation, and readmission. The presence of COPD was associated
with a lower in-hospital mortality (IHM) (OR: 0.58, 95%CI 0.57–0.59).
Conclusions
The incidence of hospitalizations for CAP increased over time in patients with and
without COPD, being higher in the COPD population for all years analyzed. IHM decreased
over time in both groups. There were no differences in mortality between COPD and
non-COPD patients.
