Current Discussions in Healthcare Environmental Asepsis

Hot Topics �One-step vs. Two-step cleaning / disinfecting �ATP testing / Fluorescent marking �Ultraviolet / Solar disinfection �Copper / Silver containing disinfectants

One-step verses Two-step

Cleaning / Disinfection �Clean �The absence of visible dust, soil, debris, blood, or other potentially infectious material �The “first step” �Disinfection �A process that kills most forms of microorganisms on inanimate surfaces �The “second step”

One-step verses Two-step �One-step product – combines detergent and disinfectant, typically packaged as single-use wipes �Two-step products – separate detergent and disinfectant, requires user to perform cleaning and disinfection in two separate steps *Products shown are for demonstration only

One-step Wipes �Various terminology used by wipe manufacturers make it difficult to choose which wipe will best fit the organizations needs �Sanitizing �Disinfectant �Germicidal �Sporicidal �Virucidal �Antibacterial *Products shown are for demonstration only

Disinfectant Wipes �While wipes have gained tremendous popularity, there is poor evidence to support efficacy at the point of care �Effectiveness of the wipe depends on… �Detergency – ability to remove dirt on a visibly soiled surface �Wetness – ability to leave a layer of disinfectant on the surface of objects / equipment �Disinfectant efficacy – once the surface is dry disinfection stops, if residue is left behind there is no further antimicrobial effect

Wipe it Out �Royal College of Nursing produced “The Selection and Use of Disinfectant Wipes” �Ultimate resource for thorough understanding of benefits and limitations of one-step wipe products �Available at http: //www. rcn. org. uk/__data/assets/pdf_file/0011/38 2538/003873. pdf

ATP testing verses Fluorescent marking

ATP testing vs. Fluorescent marking �CDC recommends all facilities develop programs to evaluate thoroughness of high-touch object cleaning �Emerging technologies take evaluation of cleaning and disinfecting beyond direct observation and checklists �Subjective evidence verses objective evidence

Objective Methods for Evaluation �Direct practice observation �Swab cultures or agar slide cultures �ATP bioluminescence �Fluorescent markers

ATP Testing �Measurement of adenosine triphosphate (ATP) on surfaces using a luciferase assay and luminometer �Method �Before room cleaning / disinfection occurs, a specialized swab obtains a sample from the surface area or object �The swab is placed in the portable hand-held luminometer which identifies the amount of ATP in the sample �After cleaning / disinfection has occurred, the items are swabbed analyzed again

ATP Testing �Advantages �Easy to use �Immediate teaching and feedback �Disadvantages �Results vary between systems �A threshold value has not been determined in the healthcare setting for determining clean / contaminated �Significant amount of ATP in the environment is nonmicrobiological �Bleach based disinfectants alter the bioluminescence reaction �Viruses and bacterial spores do not contain ATP

Fluorescent Marking �Fluorescent powder, gel, or lotion can be used to mark objects prior to cleaning �Method �Objects are marked before cleaning occurs �Evaluation occurs by shining a UV (black) light over the object to see if the product has been removed

Fluorescent Marking �Advantages �Ease of use �Immediate teaching and feedback �Disadvantages �Some markers can be seen after the mark is applied, alerting the individual to clean the tagged object more thoroughly �Some marking products can be difficult to remove from surfaces and equipment, leaving permanent stains

Comparison Method Ease of Use Identifies Pathogens Useful for Teaching Directly Evaluates Cleaning Direct Observation Low No Yes Swab cultures High Yes Unknown Not determined Agar cultures Good Limited Unknown Not determined ATP High No Yes Not determined Fluorescent marking High No Yes

Comparing ATP Monitoring Units �Article on ISSA Web site “Using an ATP Monitoring System in Healthcare Settings” �Representatives from each major industry provider of ATP monitoring systems in healthcare contributed their perspective of ATP integration into practice �Available at http: //www. fmlink. com/article. cgi? type=Magazine&ti tle=Using+an+ATP+Monitoring+System+in+Health+C are+Settings&pub=ISSA+Today&id=41190&mode=sour ce

Current Research - ATP �Sciortino, C. V. , & Giles, R. A. (2012). Validation and comparison of three adenosine triphosphate luminometers for monitoring hospital surface sanitization: A Rosetta Stone for adenosine triphosphate testing. American Journal of Infection Control, 40(8), pp. e 233. �Validation occurred for all three meters tested, but only one could be verified due to variations in system performance between units �Recommends careful consideration of technologic application in the healthcare environment

Current Research – Marking �Presentation at the International Conference on Healthcare-Associated Infections (2010) by Rupp, M. E. , Adler, A, Schellen, M. , Cassling. K. , Lyden, E. , Fitzgerald, T. , Sholtz, L. , & Carling, P. “Hospital-wide Assessment of Patient Room Environmental Cleanliness” �With the use of fluorescent marking, 10 high-touch surfaces were evaluated for cleaning efficacy � 74% of high-touch surfaces were adequately cleaned

�Several studies have shown us two certainties… �Cleaning practices are often subpar �Improvements made through education and feedback do not last �This leads us to reach out for new technologies that can be applied to the healthcare environment

Ultraviolet verses Hydrogen peroxide

Ultraviolet vs. Hydrogen peroxide �Manual cleaning / disinfection relies on the individual to follow manufacturer’s stated contact time and appropriate distribution of the chemical across surfaces �Even with vigorous cleaning, multidrug resistant organisms (MDROs) can remain in the environment for months �Both methods have published evidence of reduction of contamination in the healthcare setting

Ultraviolet Light �Acts by breaking down the molecular bonds of DNA, causing cell destruction �Requires appropriate intensity, exposure time, air movement, and bulb strength �Can be used as an adjunct to manual cleaning / disinfecting practices

Hydrogen peroxide �Acts by releasing the oxygen (oxidizing) from within the cell membrane of organisms, leading to cell death �Available as a vapor, aerosolized dry mist, and vaporized hydrogen peroxide �Active against bacteria, fungus, viruses, and spores �Numerous systems available in various price ranges �Can be used as an adjunct to manual cleaning / disinfecting practices

Comparison Method Advantages Disadvantages UV light • Effective against a wide range of organisms • Ease of use • No need to seal off air supply • Expense • Requires furniture movement • Must be placed in middle of the room • Use in unoccupied room only Hydrogen peroxide • Effective against a wide range of pathogens • More effective than manual disinfection • No toxic by-products • Disinfection of complex equipment • Room must be unoccupied • Requires sealing room and air supply • Time • Logistical issues

Current Research – UV light �Rutala, W. , Gergen, M. , & Weber, D. (2010). Room decontamination with UV radiation. Infection Control & Hospital Epidemiology, 31(10), pp. 1025 -1028. �Boyce, J. , Havill, N. , & Moore, B. (2011). Terminal decontamination of patient rooms using an automated mobile UV light unit. Infection Control & Hospital Epidemiology, 32(8), pp. 737 -742. �Both studies showed significant reduction of organisms despite high levels of contamination, including C diff spores

Current Research – Hydrogen peroxide �Falagas, M. , Thomaidis, P. , & Kotsantis, K. (2012). Airborne hydrogen peroxide for disinfection of the hospital environment for infection control: A systematic review. Journal of Hospital Infections, 78(3), pp. 171 -177. �Study shows vapor or dry mist distribution of hydrogen peroxide can effectively disinfect the hospital environment

Copper verses Silver-containing Disinfectants

Copper �Acts by altering the structure of proteins, leaving them unable to perform their natural functions (inactive) �Used in self-disinfecting surfaces �Not a cleaning / disinfection strategy, rather this is a proactive approach to decreasing microbial load

Silver Containing Disinfectants �Action is not entirely understood, but believed to have a germicidal effect on some bacteria, viruses, algae, and fungi �Not toxic to humans �Testing and standardization is difficult in the healthcare setting �Used in self-disinfecting surfaces �Not a cleaning / disinfection strategy, rather this is a proactive approach to decreasing microbial load

Comparison Method Advantages Disadvantages Copper • Not user dependent • Continuous action • • Silver • Not user dependent • Continuous action • No studies in the healthcare environment Corrosion Can irritate skin Expense Few studies available for result validation

Current Research – Copper �Karpanen, T. , Casey, A. , & Lambert, P. (2012). The antimicrobial efficacy of copper alloy furnishing in the clinical environment: A crossover study. Infection Control and Epidemiology, 33(1), pp. 3 -9. �Study found a reduction in organisms in the healthcare environment with the use of copper alloy materials �However, the items must contain greater than 58% copper
