In many hospitals, the traditional method of using buckets and towels to clean the environment has been replaced by the use of disposable disinfection wipes.
Use fluorescent dyes that are not visible in daylight. Thereafter, the surface shall be disinfected by pre soaked wet wipes or by cleaning with buckets. After 10 minutes, the operator disinfected six parts with alternative methods. Depending on the disinfection operation, the tester gets 2 points for compliance of each surface (0=dye not removed; 1=partial removal; 2=complete removal), which can get 12 points higher. In addition, the time required for disinfection was also determined. The researchers found that the compliance of operators using disposable wipes soaked in advance was significantly higher than using bucket cleaning method (compliance score 8.1 points) (compliance score 10.6 points). In addition, using disposable wipes for disinfection saves a lot of time (178.1s and 230.9s). Savings of $38.58 per operator per day.
The conclusion is that the use of disposable wet wipes soaked in advance is better than the use of bucket cleaning method, which can improve the surface disinfection process. "There are many possible mistakes in bucket cleaning, as well as many non human events." "For example, when diluting the disinfectant, it must be properly diluted. However, we often encounter problems of over dilution or insufficient dilution, which greatly affect the efficacy of the product. More and more published data show that the material quality of the wiping cloth is crucial to ensure that the disinfectant can actually be released to the surface. I know that many medical institutions still use cotton cloth soaked with quaternary ammonium compounds, which is now considered unreliable 。 Once the cleaning cloth is immersed in the disinfectant, no matter what kind of material is used in the cleaning cloth, it will generally be dried, so that the amount and concentration of disinfectant left on the cleaning cloth can not be determined (let alone a relatively dry cleaning cloth). Data shows that the bucket itself will be polluted by microorganisms, such as C. difficile spores, when using bucket cleaning method. If so, when we think we are disinfecting the site, we may be spreading the pathogen around. These kinds of events make us feel terrible. We found that it is a relatively easy and more user-friendly way to switch from bucket cleaning to a ready to use system. "
In terms of cost saving and cross contamination prevention, instant sterilized wipes may be a better method. "We found that, compared with wipes, environmental service personnel tend to quickly throw away wipes when wipes from ready to use systems fall to the floor."
