He received Master’s degree… Read more

Evolution of hand hygiene assessment tools


From UV-lamps through black boxes to the Semmelweis Scanner In our previous posts, we described what the fluorescent trial is, and when it should be applied. The conclusion was that the fluorescent trial is a quick and cost-effective solution, it is microbiologically validated, and these facts make it a great educational tool. Once we decided that it is a method for us to apply, what are the commercially available solutions? How do these systems differ in availability, capabilities and price? The minimal requirements for the fluorescent trial are a UV-lamp and fluorescent dye containing ABHR (alcohol-based handrub). We previously summarized… Read more

Why direct observation is not often objective?


Our last post addressed the Hawthorne effect, which refers to the tendency of people behaving differently when they know that they are being observed. In IPC, this leads to the overestimation of the hand hygiene compliance values [1]. Unfortunately, the Hawthorne effect is not the only bias, that can modify the results of direct observation of hand hygiene. We describe now a few more. Observer bias is often confused with the Hawthorne effect or observer effect, but it is quite different. While the Hawthorne effect describes the change of the observed person’s behavior, the observer bias is independent from the… Read more
