Knowledge score differences between clean and contaminated wrist groups were small and may not be clinically meaningful. UV light assessment found residual contamination across caregivers' hands.

No significant knowledge score differences were found for fingertips, palm, nails, dorsal hand, or interdigital spaces. Wrists are commonly neglected during handwashing.
