The effect of random voice hand hygiene messages delivered by medical, nursing, and infection control staff on hand hygiene compliance in intensive care.

Hand hygiene (HH) compliance in the intensive care unit has been studied extensively, with short-term, nonsustained compliance often because of lack of ongoing reinforcement. HH messages delivered by health care workers responsible for overseeing staff in the intensive care unit provided continuous reinforcement of HH. Compliance measured through product usage and reported as HH/bed-days increased by 60% for soap and sanitizer combined and 25% for sanitizer usage (P < 001).
