BACKGROUND:
The rise in health care-associated infections has placed a greater
emphasis on cleaning and disinfection practices. The majority of policies
advocate using detergent-based products for routine cleaning, with detergent
wipes increasingly being used; however, there is no information about their
ability to remove and subsequently transfer pathogens in practice.
METHODS: Seven detergent wipes were tested for their ability to remove and
transfer Staphylococcus aureus, Acinetobacter baumannii, and Clostridium
difficile spores using the 3-stage wipe protocol.
RESULTS: The ability of the detergent wipes to remove S aureus, A baumannii, and
C difficile spores from a stainless steel surface ranged from 1.50 log10 (range,
0.24-3.25), 3.51 log10 (range, 3.01-3.81), and 0.96 log10 (range, 0.26-1.44),
respectively, following a 10-second wiping time. All wipes repeatedly transferred
significant amounts of bacteria/spores over 3 consecutive surfaces, although the
percentage of total microorganisms transferred from the wipes after wiping was
low for a number of products.
CONCLUSIONS: Detergent-based wipe products have 2 major drawbacks: their
variability in removing microbial bioburden from inanimate surfaces and a
propensity to transfer pathogens between surfaces. The use of additional
complementary measures such as combined detergent/disinfectant-based products
and/or antimicrobial surfaces need to be considered for appropriate infection
control and prevention.
