Abstract

Sepsis is a leading cause of death. Rapid and accurate identification of pathogens and antimicrobial resistance directly from blood culture could improve patient outcomes. The FilmArray® (FA; Idaho Technology, Salt Lake City, UT, USA) Blood Culture (BC) panel can identify >25 pathogens and 4 antibiotic resistance genes from positive blood cultures in 1 h. We compared a development version of the panel to conventional culture and susceptibility testing on 102 archived blood cultures from adults and children with bacteremia. Of 109 pathogens identified by culture, 95% were identified by FA. Among 111 prospectively collected blood cultures, the FA identified 84 (91%) of 92 pathogens covered by the panel. Among 25 Staphylococcus aureus and 21 Enterococcus species detected, FA identified all culture-proven methicillin-resistant S. aureus and vancomycin-resistant enterococci. The FA BC panel is an accurate method for the rapid identification of pathogens and resistance genes from blood culture.
