User acceptability of chlorhexidine handwashes


Bottom line

A randomised study of scrubs in volunteer healthcare workers identified one of four scrub products as less suitable than others.

This was a randomised comparison of four chlorhexidine scrubs in 73 volunteers. The scrubs (Macrocide, Uniscrub, Surgiscrub, Hibiscrub) were all in original square bottles, but with bottles masked. Identical dispenser pumps delivered 4 mL per actuation.

Volunteers used a different preparation on each of four days in a randomised manner. Hands were washed without scrubbing 10 times between morning and evening, with a minimum of 15 minutes between washes. At the end of the day they scored a number of features about the product and their hands on a 100 mm VAS scale.


One preparation, Uniscrub, was chosen as least likely to be used routinely, while there was little difference between the other three. This mirrored low scores for smell, feel and lather, as well as normal hands at the end of the day.


This is an interesting model on how to involve staff in the choice of a scrub, perhaps to ensure higher compliance in their use. It certainly provides a model that could be used again.
