About

Bacteremia is a frequent infection in intensive care units. It is associated with a high mortality rate and the rapid implementation of appropriate antibiotic therapy is strongly correlated to patient clinical outcomes.

Innovative technologies have emerged to shorten the turnaround time of blood culture samples by obtaining susceptibility testing of the incriminated pathogen at an early stage, and therefore to rapidly adjust the antibiotic therapy of patients with Gram-negative Bacilli bacteremia.

The study investigators hypothesize that the implementation of the innovative BacT/Alert® VIRTUO®, BioFire® BCID2 and REVEAL® solutions for the analysis of blood culture samples will increase the proportion of patients with Gram-negative Bacilli bacteremia who receive appropriate and optimized antibiotic therapy 24 hours after blood culture collection.
