The aim of this research is to examine if the brushless scrub is effective in reducing
bioburden on the hands of the operating room (OR) personnel both with a prewash of one minute
prior to scrub and without a prewash prior to scrub, and to compare the bioburden reduction
between both methods.
Hypothesis I: A soap and water prewash used prior to brushless scrub further decreases
bioburden than brushless scrub alone.
Hypothesis II: Brushless scrub is effective in reducing the bioburden measured just after the
application of the brushless scrub within 20 seconds of application for both groups.
Exploratory Hypothesis: We will also compare the bioburden measured before and at 1.5 minutes
after application of the brushless scrub for both groups.
