Since the clostridium difficile infection (CDI) was first confirmed to be associated with antibiotic-associated diarrhea in the 1970s, the research on IT has been increasingly heated in the field of sensory control. The relevant research results have provided rich evidence-based evidence for the prevention, diagnosis and treatment of CDI, and laid a foundation for better control of CLOstridium difficile infection. The medical environment is an important medium for clostridium difficile (CD) cross transmission. How to effectively eliminate CD on the surface of the environment has been actively explored for us, such as strengthening training and education, replacing disinfectant, increasing wipe frequency, improving disinfection methods, strengthening supervision and feedback. The following study from Canada shows that different cloth materials have different effects on controlling the spread of CDS in the environment. Microfiber cloth and cotton cloth big PK, what is your choice?
Background
Environmental surfaces in healthcare facilities contaminated with Clostridium difficile spores can be an important reservoir of hospital-acquired infections. Microfiber cloths can improve the effectiveness of surface cleaning, so the purpose of this study was to evaluate whether microfiber cloths, compared with cotton cloths, can remove Clostridium difficile spores from environmental surfaces more effectively and control their spread in different environments.
Methods
A clostridium difficile spore suspension was inoculated on the surface of ceramic products (with a spore concentration of about 4.2 log10cfu/cm2). Ceramic products were selected because of the prevalence of ceramic materials in the patient's environment (e.g. flush toilets, sinks). Wipe ceramic surfaces with a microfiber cloth or cotton cloth sprayed with a buffer or non-spore cleaning agent. To ensure consistent friction and contact time, the researchers used a custom-made electric drill to simulate the wiping action of a clean surface. The pressure is maintained at 1.5-1.77 N with a total revolution of 10. The ability of microfiber and cotton cloths to remove or transfer spores was evaluated by viable count.
The results
The use of microfiber cloths reduces the risk of c. difficile spore transmission during environmental cleaning.
