Changes of resistance rates in Pseudomonas aeruginosa strains are unrelated to antimicrobial consumption in ICU populations with invasive device-related infection.

Objective: To evaluate the relationship between antipseudomonal antibiotic consumption and each individual drug resistance rate in Pseudomonas aeruginosa strains causing ICU acquired invasive device-related infections (IDRI).

Design: A post hoc analysis was made of the data collected prospectively from the ENVIN-HELICS registry.

Setting: Intensive Care Units participating in the ENVIN-UCI registry between the years 2007 and 2016 (3-month registry each year).
