KNOWLEDGE 0 20 40 60 80 100 3 mL 2 x 3 mL 3 mL Inactivation of microorganisms on hands. The reduction of colony forming units (CFU) by two VAH-listed hand disinfectants was tested in a practical contact test. Means with standard deviations and single results are shown. A high alcohol content ensures reliable inactivation of the microbial flora. More reliable inactivation of microbial flora However, high-alcohol hand disinfectants do not only score over low-alcohol products in terms of cost and time savings. In a practical test of two VAH-listed hand disinfectants [4], the highalcohol product (85% w/w) reduced the colony forming units (CFU) on the hands of the test subjects more reliably than the low-alcohol product (65% w/w), by more than 90% compared to a reduction of between 60 and 70% [5]. Safer, cheaper and more sustainable High-alcohol hand disinfectants are therefore not only more economical than low-alcohol products, but also fit seamlessly into the needs and routines of healthcare staff. In addition, their use helps to improve patient safety and the sustainability of healthcare facilities. Digital hygiene monitoring provides new insights into hand hygiene behaviour Hand hygiene is widely recognised as the most important measure in the prevention of healthcare associated infections. Hand rub dispensers are particularly suitable for collecting information on hand hygiene as a starting point for any disinfection process. This is especially true when sensors are used to record every single disinfection around the clock. Together with an academic partner and GWA Hygiene GmbH (Stralsund, Germany), the HARTMANN SCIENCE CENTER has recently published a paper on digital hygiene monitoring. In this publication, 931,446 disinfections recorded with NosoEx® from 17 wards in nine German hospitals were analysed in terms of frequency, consumption and location [1].
