Hand hygiene assessment in the workplace using a UV lamp.

The aim of this study was to determine the quality of the hand hygiene (HH) technique of healthcare workers (HCW) in real conditions, without previous education or training. All 705 participants did the World Health Organization sequence for HH correctly, but only 9.5% actually achieved the highest rating (ie, all hand areas with hand rub distribution).
