description | BACKGROUND: Ventilator-associated pneumonia (VAP) is one of the most commonly encountered hospital-acquired infections worldwide, and one of the major contributors to an over mortality in critically ill patients. Initial empirical antimicrobial therapy is often broad-spectrum. Fast identification and quantification of microorganisms is of great importance to enable early effective targeted antimicrobial treatment. This trial compares the performance of the new BioFire(®) Pneumonia Panel (BPP) with quantitative conventional culture (CC) and an independent real-time quantitative molecular-based method (MM), in Intensive Care Unit (ICU) patients with VAP suspicion. METHODS: Bronchoalveolar lavage (BAL) specimens from 120 patients with suspected VAP, enrolled at four different French ICUs, during January to November 2013, were analysed by CC, following microbiological standard procedures, by BPP and MM. A total of 15 bacterial targets, commonly detected by the three methods, were analysed for concordance above an agreed threshold for positivity. While every step is fully integrated, from specimen-to-results (BPP), bacterial DNA was extracted from each sample on the NucliSENS easyMAG® Platform, and real-time polymerase chain reactions were run in an ABI 7500 Dx thermocycler (MM). RESULTS: A total of 117 different BAL specimens were processed. Positive culture was obtained for 65.8% of BAL, while positive detections were observed in 79.4% with BPP and 75.4% with independent MM. Fourteen different species were detected by the three methods, with majority of the bacteria being S. aureus, P. aeruginosa, and H. influenzae. Overall concordance performance between BPP and CC was 89.0% (83.1%–94.9%) positive percentage agreement (PPA) and 95.9% (95.0%–96.9%) negative percentage agreement (NPA). Overall concordance between BPP and MM was 97.1% (93.8%–100.3%) PPA and 96.6% (95.6%–97.6%) NPA. Following discrepancy analyses overall performance increased to 95.3% (91.2–99.3%) PPA when comparing BPP to CC. CONCLUSION: The new BioFire® Pneumonia Panel provides reliable quantitative microbiological data in BAL specimens, in only 65 minutes, which can lead to more appropriate management of VAP suspected patients in the ICU. RUO products used in this study have not been evaluated by the FDA or other regulatory agencies for In Vitro Diagnostic use. DISCLOSURES: A. Iannello, bioMérieux: Employee, Salary. C.
