Pseudomonas aeruginosa ventilator-associated pneumonia. predictive factors of treatment failure.

Rationale: The predictive factors of treatment failure for ventilator-associated pneumonia (VAP) caused by Pseudomonas aeruginosa (PA) remain uncertain.

Objectives: To describe PA-VAP recurrence prognosis and to identify associated risk factors in a large cohort of intensive care unit patients with PA-VAP.

Methods: From the multicenter OUTCOMEREA database (1997-2011), PA-VAP onset and recurrence were recorded.
