The FilmArray® Pneumonia Plus (FA-PP) panel can provide rapid identifications and semiquantitative results for many pathogens. We performed a prospective single-center study in 43 critically ill ...patients with coronavirus disease 2019 (COVID-19) in which we performed 96 FA-PP tests and cultures of blind bronchoalveolar lavage (BBAL). FA-PP detected 1 or more pathogens in 32% (31/96 of samples), whereas culture methods detected at least 1 pathogen in 35% (34/96 of samples). The most prevalent bacteria detected were Pseudomonas aeruginosa (n = 14) and Staphylococcus aureus (n = 11) on both FA-PP and culture. The FA-PP results from BBAL in critically ill patients with COVID-19 were consistent with bacterial culture findings for bacteria present in the FA-PP panel, showing sensitivity, specificity, and positive and negative predictive value of 95%, 99%, 82%, and 100%, respectively. Median turnaround time for FA-PP was 5.5 h, which was significantly shorter than for standard culture (26 h) and antimicrobial susceptibility testing results (57 h).

Accuracy and timing of antibiotic therapy remain a challenge for lower respiratory tract infections. New molecular techniques using Multiplex Polymerase Chain Reaction, including the ...FilmArray® Pneumonia Plus Panel FAPP, have been developed to address this. The aim of this study is to evaluate the FAPP diagnostic performance for the detection of the 15 typical bacteria of the panel from respiratory samples in a meta-analysis from a systematic review.
We searched PubMed and EMBASE from January 1, 2010, to December 31, 2022, and selected any study on the FAPP diagnostic performance on respiratory samples compared to the reference standard, bacterial culture. The main outcome was the overall diagnostic accuracy with sensitivity and specificity. We calculated the log Diagnostic Odds Ratio and analyzed performance for separate bacteria, antimicrobial resistance genes, and according to the sample type. We also reported the FAPP turnaround time and the out-of-panel bacteria number and species. This study is registered with PROSPERO (CRD42021226280).
From 10 317 records, we identified 30 studies including 8 968 samples. Twenty-one were related to intensive care. The overall sensitivity and specificity were 94% 95% Confidence Interval (CI) 91–95 and 98% 95%CI 97–98, respectively. The log Diagnostic Odds Ratio was 6.35 95%CI 6.05–6.65. 9.3% 95%CI 9.2–9.5 of bacteria detected in culture were not included in the FAPP panel.
This systematic review reporting the FAPP evaluation revealed a high accuracy. This test may represent an adjunct tool for pulmonary bacterial infection diagnostic and antimicrobial stewardship. Further evidence is needed to assess the impact on clinical outcome.
