Sustainable application of ready-to-use disinfectant wipes in clinical practice: efficacy, handling, and contamination risks

BACKGROUND: Healthcare facilities face the challenge of reducing greenhouse gas emissions. In this context, the use of surface disinfectant wipes as a component of infection control requires special consideration. This study examined options for using disinfectant wipes that ensure a favourable eco-balance without compromising patient or occupational safety. User application routines and laboratory test parameters were considered. METHODS: The study comprised a clinical observational study and complementary laboratory analyses. Laboratory tests evaluated three different alcohol-based wipe types and assessed surface coverage and liquid release on different surfaces. The risk of persistent microbial contamination of the wipe after use and the risk of microbial transfer from wipe to gloved hand was investigated. In the observational study, 69 wipe procedures were recorded across three clinical departments. RESULTS: The cellulose-based wipe demonstrated superior surface coverage compared with two different wipes, with double-ply application consistently outperforming single-ply use across all wipes and all tested surfaces. The wipes fulfilled efficacy criteria even at the end of their wiping range. Transfer risk evaluation indicated that microorganisms may remain viable within the wipe and can be transferred onto gloves. Clinical observations further revealed substantial variability in folding and wiping techniques. CONCLUSION: This study highlights key aspects of surface coverage and handling-related variability, and contamination risks associated with disinfectant wipe use. The findings underscore the importance of proper wipe handling and glove use to support sustainable use of ready-to-use wipes while maintaining infection prevention standards.
