E.5 End points |
E.5.1 | Primary end point(s) |
The trial has two primary endpoints: - 1 a) Patients who switch from negative to positive in faecal tests for VRE / ESBL before versus immediately after antibiotic provocation. - 1 b) Difference in the composition, diversity and profile of the intestinal flora, before compared to directly after antibiotic provocation. |
Studien har två primära effektmått: 1 a) Omslag från negativ till positiv i fecesprov avseende VRE/ESBL före respektive direkt efter antibiotikaprovokation. 1 b) Skillnad i tarmflorans sammansättning, diversitet och profil före jämfört med direkt efter antibiotikaprovokation.

|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Directly after antibiotic treatment |
Direkt efter antibiotikabehandlingen |
|
E.5.2 | Secondary end point(s) |
The trial has three secondary endpoints 2 (a) Time until participants, who switched to positive VRE / ESBL test during antibiotic treatment, besome negative again - 2 b) Time until the composition, diversity and profile of the intestinal flora return to baseline. - 2 c) Difference in sensitivity with respect to detection of resistance genes of conventional compared to metagenomic method defined as discordant results. |
Studien har tre sekundära effektmått: - 2 a) Tid tills deltagare som slagit om till positiv återigen blir negativa avseende VRE/ESBL. - 2 b) Tid tills tarmflorans sammansättning, diversitet och profil återgår till baseline. 2 c) Skillnad i känslighet avseende detektion av resistensgener med konventionell jämfört med metagenomisk metod, definierat som diskordanta resultat.
