Implementation of rapid antimicrobial susceptibility testing combined with routine infectious disease bedside consultation in clinical practice (RAST-ID): a prospective single-centre study.

Objectives: Recently, EUCAST released guidelines for rapid antimicrobial susceptibility testing (RAST) directly from positive blood culture bottles. The aim of our prospective single-centre clinical study was to assess the proportion of readable results and errors compared with routine antimicrobial susceptibility testing and the clinical consequences drawn by infectious disease (ID) physicians from RAST results during same-day bedside consultation.

Methods: All positive blood cultures suitable for RAST from January to December 2019 were included and RAST results at 4 and 6 h compared with standard disc diffusion.
