Les surfaces de contact des surfaces biocides à fort contact peuvent être utilisées pour aider à réduire les infections nosocomiales (IAS). Bien que les protocoles bactéricides soient bien développés, les méthodes utilisées pour évaluer les propriétés virucides de ces surfaces restent très variables. Ce document cherche à identifier les méthodes les plus couramment utilisées et à évaluer de manière critique les points forts de chaque méthode en comparant les tests des organismes d’essai standard et les protocoles bactéricides connexes.
Background Biocidal high-touch surfaces contact surfaces can be used to help reduce healthcare-acquired infections (HAIs). While the bactericidal protocols are well developed, there remains high variability in the methods used to evaluate the virucidal properties of such surfaces. This paper seeks to identify the most commonly used methods and critically evaluate the strengths of each method by comparing tests from standard testing organisations and related bactericidal protocols. Methods Three databases and grey literature were queried using a key-word search for relevant articles. Articles were selected if they met the criteria of virucidal properties of self-sterilizing surfaces designed to prevent HAIs. Of the resulting 177 articles, 38 met the inclusion criteria. Results The resulting papers varied greatly in their testing methods and recommendations. Further, no standard test adequately meets the needs for specifically testing virucidal properties of self-sterilizing surfaces. Conclusions Studies have shown that temperature and humidity can affect the performance of virucidal touch-surfaces, but no standard protocols were found to test these factors.
