Deltakergruppe / Arm |
Intervensjon / Behandling |
|---|---|
|
Ingen inngripen: Velferdstandard
Når en blodkultur voksende GNB er randomisert standardbehandlingsarm, vil de positive blodkulturene bli karakterisert ved bruk av standardbehandlingstesting av antimikrobiell følsomhet (AST)
|
|
|
Aktiv komparator: Avsløre
Når en blodkultur voksende GNB randomiseres til Reveal-armen, vil den positive blodkulturen karakteriseres ved hjelp av Reveal, en rask AST, og standardbehandling AST.
|
Reveal er en rask AST-metode, som bruker sensorteknologi for små molekyler for å oppdage vekst av bakteriepopulasjoner ved å måle flyktige metabolitter, og gir AST-resultater på ~5 timer.
Reveal™ er godkjent for klinisk bruk i EU (EU) og Israel, og godkjenning er under behandling i India, og gir minimumshemmende konsentrasjoner (MIC) for 28 antibiotika og 9 gramnegative arter, som til sammen utgjør ~90 % av organismene forårsaker gramnegative blodstrømsinfeksjoner (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:
