Outline of Final Research Achievements

In this study, we examined residual bacteria on hands after cleaning with a fast-drying antiseptic handrub, either alone or after conventional hand-washing under running water. We tested 9 fast-drying antiseptic handrubs (7 standard handrubs, 2 for waterless surgical hand preparation) and 4 types of conventional hand-washing methods (one of 3 soaps or water only) with groups of 29-36 people per trial. Bacteria was lower when one of the 7 standard antiseptic handrubs, but not when the 2 for surgical hand preparation, was used alone, compared to when it was used with any type of conventional hand-washing. Among the 28 combinations, 18 had significant differences (p<0.05) in bacteria based on whether hand-washing was used. Bacteria was relatively low after cleaning with normal handwashing followed by either of the 2 types of chlorhexidine gluconate-containing (0.5 g/100 ml) surgical handrubs; this was not significantly different from when the handrub was used alone.
