The subtraction of 1 percentage from another results in a percentage point (PP) difference that provides the size of the difference; overt human auditing inflates compliance by 20 PPs to 37 PPs compared with covert automated auditing. Overt human auditing did not sustain inflated compliance estimates once auditing ceased. Neither overt human nor automated auditing changes hand hygiene compliance per se, but automated auditing improves the validity of compliance estimates. Daily feedback from automated auditing with peer nudging assisted a cooperative ward to improve, but practice was not sustained once the intervention ceased.
