1. Brushless and waterless with 1% CHG and
61% ethyl alcohol and emollients (Method C) was
significantly more effective in reducing skin colony
counts compared to brush with 4% CHG (Methods A)
and 4% CHG brushless (Method B).
2. A carryover effect was present for the
conductance data making interpretation of the results
problematic. The pre-planned analysis indicated that
Method C slightly but significantly reduced the
conductance values (reduced moisture) compared to
Method B. However, the analysis where baselines were
excluded showed no significant difference among the
methods. This was also true of the analyses run
separately for each period.
3. There was no significant difference among the
methods of surgical hand scrubs in the HSA ratings of
skin condition. However, the satisfaction scores
(easiest, fastest, like most) of Method C were
significantly higher than Method B and A.
4. The cost and time for Method C were
significantly less than Method B and A
