O065: Using adenosine tri-phosphate (ATP)-bioluminescence assay to compare outcomes of two strategies to perform environmental cleaning in a hospital setting Conference Paper uri icon


  • Hospital environment poses a substantial risk for transmission of pathogens. However, assessing cleaning efficiency is difficult and often is carried out by a subjective visual check only. The ATP-bioluminescence assay technology was developed to assist in evaluation of the environmental cleaning process by counting living and non-living organic matter in Relative Light Units (RLUs). In a 1000-bed university-affiliated hospital the standard practice following patient discharge includes terminal cleaning of the patient unit performed by nursing aides associated with the ward.
