Abstract:
We assessed the extent to which healthcare workers report more favorable hand hygiene rates when observing members of their own professional group versus other groups' observations of them. Healthcare workers consistently reported higher compliance rates for their own group compared to others' observations of them (97 vs 92%; P ≤ .001).
