Long-acting water-stable organosilane agent and its sustained effect on reducing microbial load in an intensive care unit.

Background: Contaminated hospital surfaces contribute significantly to the transmission of health care-associated infections. Although disinfectants reduce bioburden by up to 99%, bacterial growth can rebound within hours to precleaning levels. We tested the effectiveness of an innovative, long-acting water-stable organosilane (WSO) to achieve sustained decreases in bioburden on hard surfaces.
