Fecal testing results.
Patients in the BioFire FilmArray arm had a shorter median time to stool test result than those in the standard-of-care arm (median [IQR] of 3.0 h [3.0 to 4.0 h] versus 42.0 h (23.5 to 47.3 h); difference of −38.0 h, 95% confidence interval [CI] of [−41.0 to −22.0 h]). Standard-of-care testing was performed on 26 (90%) participants in the standard-of-care arm (2 children submitted specimens that were not suitable for processing by the laboratory and 1 child did not submit a rectal swab or stool specimen) and for 30 (97%) children in the BioFire FilmArray arm (1 child did not submit a rectal swab or stool specimen); those who did not have testing performed never provided a specimen. A bacterial pathogen was identified by standard testing in 37% (11/30) of children in the BioFire FilmArray arm and 35% (9/26) of those in the standard-of-care arm. The pathogens most frequently identified using standard-of-care testing were Specimens submitted and test resultsThe denominator is 31 for the BioFire FilmArray gastrointestinal panel group and 29 for the standard of care group, unless otherwise specified.Either sample type was positive. Testing was modified with culture discontinued and replaced by testing using the BDMax in June 2019.N/A, not applicable.One child <2 years of age was positive for Five children <2 years of age were All participants in the BioFire FilmArray study arm had a specimen tested on the platform and 20 (65%, with 95% CI of 45 to 81%) had a pathogen identified (
