PURPOSE: Chronic obstructive pulmonary disease (COPD) is a risk factor for acquiring multiple drug resistant bacteria. The main objective of this analysis was to question a beneficial outcome in the routine use of antipseudomonal antibiotics in the empiric treatment of severe AECOPD in Intensive Care Unit patients.

MATERIAL AND METHODS: We report a retrospective, observational cohort study in adult patients with severe AECOPD admitted to ICU at a tertiary care university hospital. Antibiotic treatment on admission as well as microbiology samples were analyzed. The influence of SOFA score at admission, age, sex and antibiotic choice upon survival was investigated by multivariable analysis.

RESULTS: 437 patients were included. Mean age was 68 years (±10), 46.5% were female. 271/437 patients (62%) were initially treated with antibiotics covering Pseudomonas aeruginosa. Overall, positive microbiology samples were found in 107 patients (24.5%). P. aeruginosa was only found in 3.7%. There was no significant difference in 30-day ICU mortality after adjusting for age, sex and severity of illness (20.4% ± 11.6 in patients with Pseudomonas inactive antibiotics versus 29.3% ± 10.8 in patients with PAA, p=0.113).

CONCLUSIONS: Empiric use of antipseudomonal antibiotics did not result in improved ICU survival in this retrospective analysis.
