P1788 Comparative evaluation of Accelerate Pheno and Vitek 2 systems for rapid antibiotic susceptibility testing of pathogens in positive blood cultures

Background: New diagnostic methods are available for rapid identification (ID) and antibiotic susceptibility testing (AST) of microorganisms responsible for bloodstream infections (BSIs). Accelerate PhenoTM system (AXDX) is an automated platform that uses morphokinetic cellular analysis to provide rapid species identification and antibiotic susceptibility directly in positive blood culture (BC) samples. The objective of the present study was to evaluate the performance of AXDX and the older VITEK 2 (VTK) system in comparison with that of conventional ID and AST methods.
