The impact of a rapid molecular identification test on positive blood cultures from critically ill with bacteremia: A pre-post intervention study

In this prospective study on critically ill with bloodstream infections, FA-BCID testing led to a substantial 10h02 time-reduction to administration of optimal antimicrobial treatment. This beneficial outcome was certainly a combined impact of the FA-BCID test (bioMerieux) and its around-the-clock realization covering time frames in which culture testing on positive blood bottles was limited or not realized. Thus 80% of the FA-BCID tests enabling a treatment switch occurred outside business hours and 54.3% overnight. This real-time approach has its usefulness for 24h/24 monitored critically ill but could lack clinical responsiveness overnight in other non-critical hospital units.
