Multisite evaluation of environmental cleanliness of high-touch surfaces in intensive care unit patient rooms.

The efficacy of discharge cleaning and disinfection of high-touch surfaces of intensive care unit patient rooms in Brazil, Canada, the Netherlands, and the United States was evaluated and the effect of an educational intervention was determined. Significant site-to-site differences in cleaning regimens and baseline cleanliness levels were observed using ATP levels, colony-forming units, and reflective surface marker removal percent pass rates. An educational intervention that includes rapid feedback of the ATP measurements could significantly improve the quality of the cleaning and disinfection regimens.
