1. Proper training of cleaning personnel and rigorous oversight and strict enforcement of cleaning routine can improve overall cleanliness and decrease bacterial load in the ward environment.
2. Multilevel antimicrobial disinfectant coating achieves consistently low bacterial load in the ward environment independent of the cleaning regimen.
3. The number of multidrug-resistant organism (MDRO)-positive environmental samples between two cleaning regimens does not differ significantly owing to rapid surface reacquisition of MDROs.
4. The occurrence of MDROs in the environmental samples is lower on surfaces coated with the multilevel antimicrobial disinfectant coating regardless of the cleaning regimen.
