The Effect of Leadership on Hand Hygiene: Assessing Hand Hygiene Adherence prior to Patient Contact in 2 Infectious Disease Units in Tuscany

We assessed hand hygiene adherence in 2 infectious disease units. In one unit, adherence declined slightly from year 1 (84.2%) to year 4 (71.0%) after a multimodal intervention but remained much higher than before intervention. Adherence dropped in the second unit after a loss of leadership (from 50.7% to 5.7%). Strong leadership presence may improve hand hygiene adherence.
