The authors reported better user acceptability for the gel. Compliance for both formulations was significantly better P 0.035 when healthcare workers had easy access to hand rubs but the difference in compliance between the gel and the liquid was not statistically significant. We are concerned that readers may conclude that gels are generally better than and preferable to liquids. The abstract points out that the gel performed significantly better on skin tolerance parameters. Easy access however was the only significant predictor for compliance. The article also mentions superior acceptance of the gel but acceptability scores of 39.1 and 40 P 0.44 were presented. Surprisingly compliance was considerably lower compared with an earlier report from the same institution 2 . The two-phase study design may have biased the results with the gel coming second and with improvements noted in the second phase. In any ongoing hand hygiene campaign it is probable that compliance and acceptability will increase with time. Also the second phase occurred during summer -a season less likely to cause dry irritant skin. Previous studies found .
