Study summary

The FDA-cleared Accelerate Pheno™ System and PhenoTest™ Blood Culture (BC) Kit will be used to assess the workflow impact of fast identification (ID)/ antimicrobial susceptibility testing (AST) in the microbiology lab and in the quality of care in patients with Gram-negative rod (GNR) bacteremia. Blood culture work up will be randomized to one of two arms: the positive blood culture will either undergo fast ID and AST using the Accelerate Pheno™ System and PhenoTest™ BC Kit or processing per the site's standard of care (SOC) procedures.

Inclusion criteria

  • Adult (≥18 years of age) hospitalized patients with positive blood culture due to gram-negative rod (on Gram stain)
  • Blood culture drawn in the Emergency Department (ED)

Exclusion criteria

Exclusion Criteria:

  • Patients not admitted to hospital
  • Patients discharged from hospital prior to blood culture positivity
  • Only the first positive blood culture for each patient of each hospitalization will be included during the study period; any subsequent episode of bloodstream infection (BSI) will be excluded
  • Positive blood culture with GNR in the prior 7 days (if known at the time of randomization)
  • Transferred from an outside hospital and had a history of a previously positive blood culture of the same organism in the prior 7 days (if known at the time of randomization)
  • GNR plus gram-positive organism, gram-negative cocci, and/or yeast detected on blood culture Gram stain
  • Deceased or palliative care at the time of randomization
  • Patient who is moribund (does not survive the initial 72 hours after enrollment)

Interventions

  • Diagnostic testAccelerate Pheno

    The Accelerate Pheno™ system and PhenoTest™ BC Kit is a fully-integrated in vitro diagnostic system. It is FDA-cleared to perform ID of bacteria and yeast in less than 90 minutes and AST in less than 7 hours, on average, directly from positive blood culture.

  • Diagnostic testStandard of Care

    Standard blood culture work up as determined by the site's microbiology lab.

What researchers measure

Primary outcomes

  1. Desirability of Outcome Ranking (DOOR) - composite outcome

    The primary endpoint is the probability that a patient will have a better DOOR when the Accelerate PhenoTest™ BC kit is used on positive blood cultures due to gram-negative rods compared to the standard of care

    Time frame: 30 days
