recorded. Failure to disinfect hands was recorded as noncompliance
(Lam et al., 2004). To determine the influence
of the education program on the consumed amount of
hand alcohol we recorded the mean 1-week amount of
applied hand alcohol per occupied bed during two periods
before and two periods after the education program.
Prior to the study the interobserver reliability had been
assessed by using Cohen’s Kappa. The mean Kappa was
above 0.86, which indicates very good agreement.
