Our objective was to evaluate the diagnostic yield and accuracy of the BioFire FilmArray pneumonia panel (BFPP) for identification of pathogens in lower respiratory tract specimens ( = 200) from emergency department (ED) and intensive care unit (ICU) patients at a tertiary care academic medical center. Specimens were collected between January and November 2018, from patients ≥18 years of age, and culture was performed as part of standard-of-care testing. The BFPP identified a viral or bacterial target in 117/200 (58.5%) samples, including in 22% of samples and in 14%, and both a viral and bacterial target in 4% of samples. The most common viruses detected by BFPP were rhinovirus/enterovirus (4.5%), influenza A virus (3%), and respiratory syncytial virus (RSV) (2%). Overall, there was strong correlation between BFPP and standard methods for detection of viruses (99.2%) and bacteria (96.8%). Most bacteria (60/61 98.4%) detected by standard methods were also identified by BFPP, and 92 additional bacteria were identified by BFPP alone, including 22/92 (23.9%) additional isolates and 25/92 (27.2%) isolates, which were more frequently discordant when detected at low concentrations ( , < 0.001; , < 0.0001) and in sputum-type specimens ( , < 0.05). A potential limitation of the BFPP assay is the absence of fungal targets and , which were detected in 26 and 4 of 200 specimens, respectively. Real-time specimen analysis with BFPP has the potential to identify bacterial pathogens and resistance markers 44.2 and 56.3 h faster than culture-based methods. The BFPP is a rapid and accurate method for detection of pathogens from lower respiratory tract infections.
