Abstract Background Environmental contamination contributes to hospital associated infections, particularly those caused by multi-drug resistant organisms (MDRO). This study investigated bioburden presence on surfaces in a critical care center’s patient rooms following typical environmental services (EVS) practices and following intervention with hybrid hydrogen peroxide™ (HHP™) fogging. Methods Upon patient discharge, following standard cleaning or cleaning with ultraviolet (UV) light use, patient rooms were sampled by swabbing for adenosine triphosphate (ATP) and aerobic colony counts (ACC) from five preset locations. Rooms were then fogged via HHP technology using chemical indicators and Geobacillus stearothermophilus biological indicators for sporicidal validation monitoring. Following fogging, rooms were sampled again, and results were compared. Results A 98% reduction in ACC was observed after fogging as compared to post EVS practices both with and without UV light use. No statistical difference was seen when comparing cleaning to cleaning with UV light use. Methicillin-resistant Staphylococcus aureus (MRSA) and Pseudomonas aeruginosa were identified following EVS practices and not detected following HHP fogging. ATP samples were reduced 88% by fogging application. Chemical and biological indicators confirmed correct application of HHP fogging, as seen through its achievement of a 6-log reduction of bacterial spores. Conclusion HHP fogging is a thorough and efficacious technology which, when applied to critical care patient rooms, significantly reduces bioburden on surfaces, indicating potential benefits for implementation as part of infection prevention measures. |
