This study will evaluate the immediate antimicrobial efficacy and persistence of two hand hygiene products on ICU Health Care Worker's skin flora by measuring bacterial organisms on hands using the hand print method. It is hypothesized that the product containing Chlorhexidine gluconate will provide more persistence than the alcohol product, resulting in less bacterial growth on the hand print plates. In addition, environmental monitoring for cleanliness will be captured from high touch surfaces in ICU patient rooms and common areas using Rodac plates and adenosine triphosphate tests.
