Use of a Rapid Diagnostic Test for Antibiotic De-escalation in Severe Community Acquired Pneumonia (BioFire)

March 1, 2021 updated by: Richard Wunderink, Northwestern University
The purpose of this study is to conduct an open-label step-wedge pilot clinical trial to compare an antibiotic strategy based on routine use of a novel rapid diagnostic test to usual care in critically ill adults with severe community acquired pneumonia (SCAP). We hypothesize that when results from a rapid diagnostic test (RDT) are used to guide antibiotic therapy, broad-spectrum antibiotic exposure will be reduced in critically ill patients with SCAP without an increase in adverse events.

Description

Inclusion Criteria:

  1. Adults aged 18 years and older with known or suspected community-acquired pneumonia who are admitted to the MICU Service

  2. Meets one of the following:

    1. Have or plan to obtain a bronchoalveolar lavage (BAL)
    2. Have or plan to obtain a quantitative endotracheal aspirate sample
    3. Have already produced a high-quality sputum sample if not intubated
  3. Primary MICU attending and fellow willing to base antibiotic therapy on results of RDT

Exclusion Criteria:

  1. Subjects with confirmed extrapulmonary infection requiring antibiotics outside the usual treatment for SCAP, with the exception of suspected uncomplicated urinary tract infection
  2. Neutropenic fever, defined as absolute neutrophil count <1000/mm3 and absence of infiltrate on available chest imaging
  3. Chronic airway infection, defined as cystic fibrosis, lung transplant, or non-CF bronchiectasis
  4. Patient/surrogate refusal
  5. Inability to perform BAL, NBBAL, quantitative ETA, or produce a high-quality sputum sample prior to 48 hours from hospital admission

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
No Intervention: Control
Critically ill patients with pneumonia will be treated with an antibiotic strategy at the discretion of the treating clinician
Experimental: Interventional
Critically ill patients with pneumonia will be treated with an antibiotic strategy based on results from the BioFire Pneumonia Panel
Diagnostic test: BioFire Pneumonia Panel
Treatment based on an algorithm that recommends antibiotic choices based on bacteria/virus detected by BioFire Pneumonia Panel
