Electronic Monitoring Increases Healthcare Worker Hand Hygiene Rates *

“The New Jersey Hospital Association reported: “Hand hygiene rates were found to be three times higher when auditors were visible to healthcare workers than when there were no auditors present, according to a study published online in the BMJ Quality & Safety Journal.
The study, “Quantification of the Hawthorne Effect in Hand Hygiene Compliance Monitoring Using an Electronic Monitoring System: A Retrospective Cohort Study,” examined the Hawthorne effect, also known as observation bias. This is the tendency of people to change their behavior when they are aware of an observer.
The study used an electronic monitoring hand hygiene system in real-time, eliminating many of the biases inherent to human observation. Ultrasound “tags” on soap dispensers transmitted a signal to a nearby receiver each time the levers were pushed, and a time-stamped hand hygiene wash was recorded in a central data base.
There was an approximately three-fold increase in the rate of hallway hand washes per hour among healthcare staff when an auditor was visible (3.75 per hour), compared to a location where the auditor was not visible (1.48 per hour) and to the previous weeks (1.07 per hour), the study suggests.
The study concluded that a front-line staff ownership approach, which engages rather than “nags” staff is a good option.”
