Tackling contamination of the hospital environment by methicillin-resistant Staphylococcus aureus (MRSA): a comparison between conventional terminal cleaning and hydrogen peroxide vapour decontamination.

摘要: The hospital environment can sometimes harbour methicillin-resistant Staphylococcus aureus (MRSA) but is not generally regarded as a major source of MRSA infection. We conducted prospective study in surgical wards London teaching affected by MRSA, and compared the effectiveness standard cleaning with new method hydrogen peroxide vapour decontamination. contamination, measured surface swabbing was before after terminal that complied UK national standards, or All isolation rooms, ward bays bathrooms tested were contaminated several antibiogram types identified. common sites might transfer organisms to hands staff isolated from areas bed frames used non-MRSA patients. Seventy-four percent 359 swabs taken yielded 70% direct plating. After cleaning, all remained contaminated, 66% 124 yielding 74% In contrast, exposing six rooms vapour, only one 85 (1.2%) enrichment culture only. become extensively eliminated methods. decontamination highly effective eradicating furniture equipment. Further work needed determine importance environmental contamination effect on infection rates
