[Efficiency and Usefulness of the Molecular Test 'Biofire^®Filmarray^® Blood Culture Identification 2' in the Quick Diagnosis of Bacteraemias in a Burns Intensive Care Unit].

Abstract

. The sensitivity and specificity of the test for detecting resistance genes were 84.1% and 92%. The turnaround time (TAT) for molecular test results was 1 hour and 10min (Q1 1.09 h; Q3 1.12 h). The median TAT for BCID2 was significantly (Mann-Whitney, p<0.0001) shorter than for conventional culture 39.1 h (Q1 33 h; Q3 57.6 h). Antimicrobial therapy was modified on the basis of the molecular test results in 35.3% of patients. This was done within a median of 04 hours of receiving the test result [interquartile range 2.4h - 21h]. A favorable outcome was noted in 70% of these patients.
