STUDIES PRACTICE A new study involving the HARTMANN SCIENCE CENTER - conducted by an independent accredited test laboratory - shows that two disinfectants from the Sterillium® range meet the bactericidal efficacy requirements for hygienic hand disinfection according to the EN 1500 test standard with an exposure time of 15 seconds [1]. EN 1500 [2] does not currently allow for testing of less than 30 seconds. Therefore, the minimum contact time stated by the manufacturer is 30 seconds, but this is not always adhered to in everyday clinical practice. The two Sterillium® products - one ethanolic, one propanolic - were compared with the unmodified reference at a 15 second rubin time using two different rub-in techniques and volumes. The result: Both products were not inferior to the reference in either technique and therefore met the efficacy requirements of EN 1500 after just 15 seconds [1]. References 1. Mönch E et al.

Selected hand disinfectants fulfil the requirements Now that HARTMANN has been successfully marketing the NosoEx® hand hygiene monitoring system in Germany for two years, the first pilot projects in other EU countries began this year. One of the two pilot projects in Hungary is taking place in the neonatal intensive care unit at Semmelweis University in Budapest. To reduce the number of nosocomial infections in his department, Dr Csaba Nádor, head physician, wanted to use a new, innovative approach to better understand the current level of hand hygiene and to provide impetus for improvement. As part of the 6-month project, NosoEx® sensors were attached to all hand disinfection dispensers to record and automatically analyse all hand disinfections. In addition, transponders were given to ward staff and parents to monitor the hand hygiene behaviour of each group and remind them to disinfect their hands regularly. To analyse habits, knowledge, motivations and fears regarding hand disinfection and electronic monitoring, questionnaires were given to the staff in advance and will be repeated towards the end of the project to see what effect the pilot has had. The first successes are already evident in the fact that more hand disinfections are being carried out than before. The next step is to establish the habit of using a sufficient amount of hand disinfectant. The results of the intervention will then be published. The NosoEx® system is also in use at the Emergency Centre of the Medical University of Pécs. A structured intervention program will be developed for this site in the near future.
