The effects of a prospective sink environmental hygiene intervention on Pseudomonas aeruginosa and Stenotrophomonas maltophilia burden in hospital sinks

https://pubmed.ncbi.nlm.nih.gov/40398352/ AHRQ-supported researchers found that implementing an intensive care unit sink cleaning intervention 5 days a week using 10 percent bleach wipes to clean sink surfaces, plus pumping pre-acid disinfectants into hospital sink drains, reduced the proportion on Gram-negative bacteria by up to 85 percent. Counts of Pseudomonas spp. and Stenotrophomonas spp., also known as opportunistic premise plumbing pathogens, which can colonize the drains and cause healthcare-associated infections, dropped by up to 100 percent and 95 percent from the baseline when this 5-day-per-week, high-frequency treatment was implemented
