EUCAST rapid antimicrobial susceptibility testing (RAST) compared to conventional susceptibility testing: implementation and potential added value in a tertiary hospital in Belgium.

EUCAST RAST is an inexpensive and reliable method of susceptibility testing, although care must be taken with reporting piperacillin/tazobactam. In support of RAST implementation, we show that AST remains of great importance in providing effective therapy, even in a setting of low MDR prevalence and elaborate antibiotic guidelines.
