Increased Mortality Risk Associated with Chronic Obstructive Pulmonary Disease (COPD)

Abstract

Background: Community-acquired pneumonia (CAP) is a leading cause of hospitalization and mortality worldwide. Chronic obstructive pulmonary disease (COPD) is a common comorbidity in patients with CAP, potentially worsening outcomes. This study investigates the association between COPD and adverse outcomes in patients admitted with CAP. A retrospective review of 100 patients with CAP revealed that those with underlying COPD had significantly higher in-hospital mortality, ICU admission rates, and prolonged hospital stays. Materials and Methods: A total of 100 adult patients diagnosed with CAP were included in the study. Patients were stratified based on the presence or absence of COPD. Results: Of the 100 patients, 40% had a history of COPD. Patients with COPD showed higher ICU admission rates (55% vs. 20%), increased in-hospital mortality (25% vs. 8%), and longer average hospital stays (9 vs. 5 days). Conclusion: The presence of COPD in patients with CAP is associated with increased mortality, ICU admissions, and prolonged hospitalization. COPD should be considered a key prognostic factor in managing CAP.
