Patient specimens with positive blood culture with Gram stain showing GNB identified during local laboratory business hours will be enrolled by the Microbiology Laboratory Technologist if they do not meet any exclusion criteria. Subject specimens will be randomized 1:1 to standard culture and AST or Rapid identification and AST using the FDA approved Accelerate Pheno TM System. Both groups will receive standard antimicrobial stewardship (AS). The primary service, including the prescribing provider, will be unaware of group assignment at the time of randomization, so initial antibiotic choice will not be affected by group assignment. Once rapid results become available and/or AS interventions are made, treating providers may become aware of group assignment.
