Abstract:

Hand hygiene compliance is subject to the Hawthorne effect, which may be attenuated by covert observers and brief observation periods. This study demonstrated that hand hygiene compliance rates were between 8% and 29% greater when reported by infection prevention programs than when reported by covert observers over brief observation periods.
