Which statement is accurate concerning alcohol-based hand rub (ABHR)?

The statement that alcohol-based hand rub (ABHR) is the most effective product for reducing the number of pathogens on hands is accurate because ABHR, when applied correctly and to dry hands, effectively kills a wide range of pathogens, including bacteria and viruses. The alcohol concentration in these products typically ranges from 60% to 95%, which is optimal for antimicrobial action.

ABHRs are particularly beneficial in healthcare settings because they are quick to use, do not require water, and significantly reduce the time needed for hand hygiene compared to traditional handwashing with soap and water. They also minimize skin irritation when compared to repeated washing. It is important to note that while ABHR is effective, its use is most appropriate when hands are not visibly soiled, as visible dirt or organic matter may inhibit its effectiveness.

In contrast, other statements suggest limitations or inaccuracies about ABHR. For instance, the claim that ABHR is less effective than soap and water does not hold true in most situations where soap and water are not needed to remove dirt or grease. Moreover, the statement that ABHR should only be used when hands are visibly dirty contradicts current infection control practices that recommend hand hygiene to be performed with ABHR when hands are not visibly contaminated.
