Abstract
Increasing normative demands on patient safety and quality assurance measures, but also the problem of multi-resistant germs and pathogens with a high potential for infection, increase the need for hygienically correct work.In this study, hygienically relevant potential sources of contamination in ENT examinations were to be identified and possible improvement strategies examined.A complete ENT examination was performed by 5 examiners with different professional experience, whose gloves were wetted with fluorescent lotion prior to the examination. Contaminations especially on the examination unit and on the instruments were identified. The potential risk of transmission of pathogens to subsequent patients was assessed using a specially developed score. Various strategies to reduce identified contamination possibilities were developed and thought through.The score of the investigators was very high with an average of 87.4 points (±3.6). The implementation of individual hygiene measures during the examination process would lead to a significant reduction of the score and thus to an improvement in hygiene: No shaking of hands (81.8), additional disinfection of patient's chair (79.8), disinfection of important surfaces (69.8), provision of standard instruments (60.2) or all instruments (32.2), disinfection of all relevant surfaces and provision of all instruments (7.4).The results show very clearly that an ENT examination is a complex procedure from the point of view of hygiene. For reliable protection against possible transmission events, a structured bundling of hygiene measures is therefore necessary.
