Applying alcohol-based handrubs (ABHRs) can be a key factor in controlling the spread of infection, yet only if the proper amount of an effective handrub formulation is used. Healthcare workers often prefer to apply small ABHR amounts, since it dries faster. In response to this market preference, dispenser manufacturers tend to design their dispensers to dose small amounts. This study aims to investigate whether manufacturers' preset volume is suitable to achieve complete coverage. Medical students were asked to perform hand hygiene using foam format handrubs from three different wall-mounted, automatic dispensers. Drying time and hand coverage were objectively measured at each hand hygiene event. Participants were also asked to qualitatively assess the amount of ABHR received. 60 medical students tried all three dispensers, applying either one or two doses from each. Hand coverage strongly correlated with the applied ABHR volume. When less than 1 ml of handrub was applied, more than 10% of the hand surface was missed. Drying time appeared to be a limiting factor: when 2.6 ml of handrub was applied, the average drying time was 47.5 seconds. The participants' perception of the amount of ABHR received was inconsistent. As the dispensed ABHR volume determined the coverage achieved, it should be among the key indicators of quality when selecting a dispenser for installation. Participants frequently misjudged whether the received handrub amount was appropriate, suggesting that we cannot rely on people's intuition. Higher volumes cover the hands better, but require longer drying times, which can impede compliance.
