Chemical disinfectants: Controversies regarding their use in low risk healthcare environments (part 1).
Journal of infection prevention(2019)
摘要
In recent years, the number of disinfectants designed to decontaminate healthcare environments and reusable, non-invasive care equipment (NICE) has increased markedly, making the selection of the most appropriate disinfectant a somewhat daunting prospect. In addition to the microbial challenge, there are numerous factors to consider including: efficacy; range and speed of activity; stability of the ingredients; compatibility of the disinfectant with surfaces; inactivation of the disinfectant by organic matter; method of application; convenience; health and safety concerns; and cost. While the microbial challenge continues to evolve, and novel disinfectants continue to emerge, guidance updates have been notably absent. Most healthcare surfaces belong to a UK-defined category of 'low risk' for which guidance dictates 'cleaning and drying is usually sufficient'. This paper assesses the evidence and arguments regarding the use of disinfectants for low-risk healthcare surfaces. A novel subcategorisation of 'low risk' is presented to provide a more specific up-to-date disinfectant needs assessment.
