The impact of VITEK 2 implementation for identification and susceptibility testing of microbial isolates in a Brazilian public hospital.

The use of automated systems in identification and susceptibility tests can improve antimicrobial therapy, and positively impact clinical outcomes with a decrease in antimicrobial resistance, hospitalization time, costs, and mortality. The aim of this study was to evaluate the clinical impact of an automated method for identification and susceptibility testing of microbial isolates. This was a retrospective cross-sectional study aimed to analyse the results before and after the implementation period of a VITEK 2 system in a Brazilian university hospital.
