Assessment of an innovative antimicrobial surface disinfectant in the operating room environment using adenosine triphosphate bioluminescence assay.

Terminal cleaning in the operating room is a critical step in preventing the transmission of health care-associated pathogens. The persistent disinfectant activity of a novel isopropyl alcohol/organofunctional silane solution (ISO) was evaluated in 4 operating rooms after terminal cleaning. Adenosine triphosphate bioluminescence documented a significant difference (P < .048) in surface bioburden on IOS-treated surfaces versus controls. RODAC plate cultures revealed a significant (P < .001) reduction in microbial contamination on IOS-treated surfaces compared with controls. Further studies are warranted to validate the persistent disinfectant activity of ISO within selective health care settings.
