Measuring the Impact of an Enhanced Strategy for Daily Disinfection in Acute Care Hospital Rooms

The study Investigator will evaluate the effectiveness of a) adding sani24 to the standard daily cleaning and b) routine daily disinfection in acute care hospital rooms to measure the reduction in bioburden. In other words, the study aims to answer the following research question: does the addition of an additional disinfection technology (Sani24) decrease the environmental bioburden in inpatient hospital compared to routine disinfection?

This trial was conducted in acute care hospital rooms at Duke University Hospital in Durham, North Carolina from November 2021 to March 2022. Room surfaces were divided in two (e.g., right vs. left), allowing each patient room to serve as its own control. The intervention was a quaternary ammonium salt-based 24-hour continuously active germicidal wipe, Sani-24 (PDI Healthcare, Woodcliff, NJ) that was applied in addition to routine disinfection. The control arm received no intervention beyond routine disinfection. Environmental services were blinded to study arms and no changes to routine cleaning protocols occurred during the study period. Room contamination was measured immediately before the application of the disinfectant (study day 0) and 24-hours later (day 1). Secondary outcomes included evaluation for clinically important pathogens (CIP), including methicillin-resistant staphylococcus aureus (MRSA), vancomycin-resistant Enterococcus (VRE) and carbapenem-resistant Enterobacteriaceae (CRE)
