Infection Prevention with Darrel Hicks

Question: What are the top SIX activities in cleaning that will have the greatest impact on safety and health?
Answer: Here is my list of the top SIX activities necessary to impact the health and safety of our public.

Train and retrain housekeepers (custodial staff) that their role is NOT cleaning for appearance sake, but for “health’s sake.” For too long we have judged the cleanliness of surfaces based on a shiny floor, smudge-free glass, spot-free carpet and a clean nice smelling restroom. The indoor environmental surfaces can be clean, but unhealthy or unsanitary. BUT, if those same surfaces are healthy and sanitary, THEY ARE CLEAN! There is a science to cleaning and disinfecting. The Environmental Services (ES) staff performs both the a.) Clinical function of removing and inactivating/killing HAI producing microbes, and, b.) The practical function of cleaning by restoring the room to order after soil removal activities are completed.

The time has come to turn cleaning professionals into Certified Environmental Services Technicians (CEST). Moreover, infection prevention will only become a reality when the CEST is properly regarded, educated and equipped. The certified technician must be: a) Well trained and coached; b) Equipped with the necessary tools to clean, sanitize and/or disinfect; c) Allotted time to do the necessary tasks; d) Provided the tools to enable scientific measurement of “clean”; e) Educated about the prevention and transmission of disease.

Train those who clean that there is a pattern for cleaning; Clean the room from top, down and from the cleanest part of the room to the dirtiest; leave the rest room for last. When cleaning the “patient zone” (the area 3′ [1 meter] around the patient’s bed, including the bed rails); use a fresh, clean cloth for the patient’s zone.

Never double dip a cleaning cloth. Set up a bucket of properly diluted disinfectant at the beginning of the shift; add 10-15 microfiber cloths to the bucket. Reach into the bucket for a clean, disinfectant-charged cloth; NEVER return (double dip) a soiled cloth into the solution bucket. The analogy I like to use is this; when you pull a disposable disinfectant wipe from a container and use it to wipe a soiled surface, do you return it to the container? No, it is disposed of. The same should be true for soiled microfiber cleaning cloths…they are put into a bag to be laundered daily.

Using a quaternary ammonium disinfectant with “retired” cotton cleaning cloths (i.e., surgical towels, terry cloth towels and washcloths) and mops is counterproductive. Unfortunately, this combination is used in most hospitals and hotels. The cotton in these retired cloths inactivates quat disinfectants by binding the active ingredients to the cotton rather than releasing them to the surface. This happens within 5 minutes of introducing cotton to the bucket of quat disinfectant. In fact, you might as well be using water after 5 minutes because the ppm of active ingredients is out of specification for EPA registration. At that point, you are using the product “in a manner inconsistent with the manufacturer’s label” and are in violation of US federal law.

Regardless of whether or not a “One-Step” disinfect (manufacturer claims surfaces do not need to be pre-cleaned) or a “Two-Step” disinfectant (must be applied to pre-cleaned surfaces) is being used, the surface SHOULD be cleaned with a general purpose cleaner and a high denier microfiber cloth for soil removal and followed by the disinfectant of choice. The AOAC testing that is done on disinfectants before submitting them to the US EPA for registration is “in the presence of 5% blood serum.” If surface soil is greater than 5%, the disinfectant is most likely over challenged (ineffective due to the soil load). For a surface to have greater than a 5% soil load, the soil most likely is NOT VISIBLE. If 90-95% of the soil (and micro-soil) can be removed with a general-purpose cleaner and superior microfiber cloth, most of the food and moisture necessary for microorganisms to survive on a surface are removed. Then, the disinfectant that is applied has a much better chance of killing the remaining microorganisms.

Reasons to Change to Microfiber Cloths

When it comes to the prevention of the spread of diseases the custodians are the first line and last line of defense. With 80 percent of infections being caused through direct contact there won’t be anything stopping these bacteria if the custodians aren’t equipped with the right tools. This doesn’t mean having to buy thousands of dollars worth of heavy duty equipment for your facility, but instead just to make sure not to cut corners on the cheaper things that you need to clean and disinfect your facility.

So do you want to be in a facility were the bacteria and soil is being spread around by cotton cloths or to ensure that the soil and bacteria is getting picked up through the use of Microfiber Cloths?

When cleaning with traditional cotton rags in most situations you will be picking up a good majority of bacteria, but this is only half the battle when it comes to cleaning and disinfecting. The true challenge is not to just remove the bacteria from a surface, but the soils from the surface as well to give the disinfecting chemicals a fighting chance according to Darrel Hicks, author of Infection Prevention for Dummies. Cotton rags while cheap and readily available, are not particularly good at picking up these soils off of surfaces which is one of the problems of using cotton rags.

Microfiber cloths on the other hand work by gently scrapping against the surface to help pull the soil and bacteria off of the surface. They then use their engineered pockets within their fabric to collect and trap the soil until the cloths are washed to prevent from spreading it across the surface. Making them extremely effective in preparing a surface to be disinfected.

Another problem that cotton cloths have is when you are using quat-based disinfectants. The cloths can have a strong attraction with the active ingredients in these quat disinfectants, which causes the cloths to spread the soil and bacteria rather than picking it up off the surface.

At The University of Minnesota Medical Center they tested the efficiency of both cloth and microfiber cloths, which led their decision to switch to microfiber.

The University found that Microfiber cloths will pick up spores and microorganisms even if you don’t use disinfectants were as cotton will just spread them across the surface. As well according to Amanda Guspiel, environmental infection preventionist since using these microfiber cloths they have not had any issues with quat binding that can occur with cotton rags.

Through changing to microfiber Guspiel has had a decrease in the number of Hospital acquired infections.
