Bacterial infection and risk factors in outpatients with acute exacerbation of chronic obstructive pulmonary disease: A 2‐year prospective study

Abstract

There was a higher incidence of Moraxella catarrhalis and Pseudomonas aeruginosa than reported in previous studies. These findings should influence antibiotic selection for exacerbations. COPD patients with a low baseline PEF are at a higher risk of having repeated exacerbations and gram-negative pathogens.
