Våben og indgreb
Deltagergruppe / Arm |
Intervention / Behandling |
|---|---|
|
Ingen indgriben: Standard for pleje
Når en blodkultur, der vokser GNB, er randomiseret standardbehandlingsarm, vil de positive blodkulturer blive karakteriseret ved hjælp af standardbehandlingstest af antimikrobiel følsomhed (AST)
|
|
|
Aktiv komparator: Løfte sløret
Når en blodkultur, der vokser GNB, randomiseres til Reveal-armen, vil den positive blodkultur blive karakteriseret ved hjælp af Reveal, en hurtig AST og standardbehandlings-AST.
|
Reveal er en hurtig AST-metode, som bruger sensorteknologi med små molekyler til at detektere vækst af bakteriepopulationer ved at måle flygtige metabolitter og giver AST-resultater på ~5 timer.
Reveal™ er godkendt til klinisk brug i EU (EU) og Israel, og godkendelse er i gang i Indien og giver minimumshæmmende koncentrationer (MIC'er) for 28 antibiotika og 9 gramnegative arter, der tilsammen udgør ~90 % af organismerne forårsager gramnegative blodstrømsinfektioner (BSI).

Participant Clinical Outcomes, as Measured by Desirability of Outcome Ranking (DOOR)
Tidsramme: Up to 30 days after Gram stain result
|
The composite 3-category DOOR outcome will assess three deleterious events (unsuccessful discharge, lack of clinical response, and undesirable events) in addition to survival up to 30 days after Gram stain result. The primary DOOR outcome measure is defined using three ordered levels. From best to worst, they are:
