A superb cluster randomised trial has just been published in Clinical Infectious Diseases testing whether improved environmental hygiene via objective monitoring and feedback reduces HCAI. The study also tests whether ATP or UV fluorescent marker monitoring is more effective. The findings reinforce that improving environmental hygiene reduces HCAI, and (I think surprisingly) suggest that ATP is more effective than UV monitoring.
