The study aims to assess the significance of Pseudomonas aeruginosa colonisation in patients without bronchiectasis in COPD.
Retrospective review of cases from April 2012 to April 2013
Analysis of patient records with positive sputum growth of Pseudomonas
Categorization of patients by lung function and bronchiectasis presence
20% of patients colonised with Pseudomonas did not show radiological evidence of bronchiectasis
60% of non-bronchiectasis patients had airway obstruction
96% of patients with bronchiectasis were on high dose inhaled corticosteroids

Adizie et al. (2014) studied this question.
