Adherence to ecology monitoring
Most patients (91–99% across periods) had swab samples taken at admission to the PICU. However, study-specific ecology was impacted by a low rate of consent (44% of enrolled children) for ongoing (twice-weekly) screening swabs. When consent was obtained, adherence to the sampling regimen was good with samples collected for more than 90% of eligible patients at each timepoint. There was good collection of all routine microbiology cultures and antimicrobial administration during the PICU stay.
