Is screening of patients for Pseudomonas aeruginosa groin/rectal carriage useful in identifying those at risk of bacteraemia in haematology and other high-risk clinical settings?

Rectal/groin swab-screening at admission to hospital might be valuable for early detection of patient colonization but it is intrusive, resource-demanding, and yield may be low. In high-risk settings, enhanced environmental monitoring, decontamination of surfaces and drains, and point-of-use filter-barriers is recommended, especially if expected duration of stay exceeds 30 days.
