Implementing carbapenem-resistance testing algorithms for Enterobacteriales and Pseudomonas aeruginosa: diagnostic and antimicrobial stewardship with timely infection prevention

Abstract

Early detection of carbapenem resistance in Gram-negative (CRGN) infections can help tailor therapy sooner and prevent horizontal transmission more efficiently. This involves timely, multidisciplinary communication. To this aim, we describe our experience with implementing reflex testing algorithms for expanded antibiotic susceptibilities and molecular mechanisms of resistance in a large academic hospital.
