The goal must be the effective elimination of “problem pathogens” or at least reduction of the microbial load to an extent that reduces the risk of infection and prevents spread to other patients. A key practice with a high level of scientific evidence is the preventive patient decolonisation (universal / horizontal patient decolonisation.
A comprehensive screening is dispensed with here. Instead, all patients – irrespective of their microbial status – commence decolonising washes on admission to their respective wards.
Ideally, this involves simultaneous decontamination of the nasal vestibules, the whole of the skin and any wounds.
