Researchers Measure Effectiveness of Spray Bleach Formulation

The frequency of recovery of Clostridium difficile spores from surfaces after postdischarge cleaning of non-C difficile infection rooms was significantly reduced from 24%-5% after a commercial spray formulation of bleach was substituted for a quaternary ammonium disinfectant. These results suggest that routine use of a sporicidal disinfectant in all postdischarge rooms could potentially be beneficial in reducing the risk for C difficile transmission from contaminated surfaces.
