For example, an overall CFU/cm2 count of 0.08 in single-occupancy rooms two weeks before relocating is a decrease of 89% compared to a CFU count/cm2 of 0.74 in the old building. This is a significant reduction, indicated by the color of the cell. Green cells indicate a significant decrease in CFU counts, red cells indicate a significant increase in CFU counts. Light green/light red 0.05<P<0.01, Green/Red 0.01≤P<0.001, Dark green/dark red P≤0.001. Before; before relocating patients, After; after relocating patients. Abbreviation: CFU colony forming units. a The RODACs for the single-occupancy rooms and bathrooms were accidentally incubated for 24 hours instead of 48 hours b Singleoccupancy rooms were compared with the combined median CFU counts per cm2 of two- and four patient rooms in the old hospital building. 158 Chapter 3.2
