In the AMR era, the clinical utility of the BioFire FilmArray Pneumonia Panel Plus (BFPP) to diagnose HAP\/VAP has not been thoroughly evaluated.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We enrolled adult hospitalized patients with HAP or VAP at Siriraj Hospital and Saraburi Hospital from July 2019\u2013October 2021.

The median duration of HAP\/VAP diagnoses was 10.5 (5, 21.5) days, and 36 endotracheal aspirate and 4 sputum samples were collected. Standard cultures isolated 54 organisms\u2014<jats:italic>A. baumannii<\/jats:italic> (37.0%), <jats:italic>P. aeruginosa<\/jats:italic> (29.6%), and <jats:italic>S. maltophilia<\/jats:italic> (16.7%). 68.6% of Gram Negatives showed an MDR or XDR profile. BFPP detected 77 bacterial targets\u2014<jats:italic>A. baumannii<\/jats:italic> 32.5%, <jats:italic>P. aeruginosa<\/jats:italic> 26.3%, and <jats:italic>K. pneumoniae<\/jats:italic> 17.5%. Of 28 detected AMR gene targets, CTX-M (42.5%), OXA-48-like (25%), and NDM (14.3%) were the most common. Compared with standard testing, the BFPP had an overall sensitivity of 98% (88-100%), specificity of 81% (74-87%), positive predictive value of 60% (47-71%), negative predictive value of 99% (96-100%), and kappa (<jats:italic>\u03ba<\/jats:italic>) coefficient of 0.64 (0.53-0.75). The concordance between phenotypic AST and detected AMR genes in <jats:italic>Enterobacterales<\/jats:italic> was 0.57.
