Compared with the positive culture group, the negative group performed better in hand hygiene (χ2=17.624, P<0.01), and the frequency of the case sterilization in the negative group (χ2=43.754, P<0.01), cleaning frequency (χ2=69.737, P<0.01) were higher than the positive group. In the choice of cleaning methods, the proportion of using brushing (χ2=65.441, P<0.01) and re-rinsing (χ2=59.663, P<0.01) in the negative group was higher than that of the positive group.
