“…We defined RLU thresholds, based on literature review and on previous ATP measurements in the participating hospitals before the project started [8]. Other studies have recommended an RLU threshold for cleanliness at 250-500 RLU, however this threshold is intended for measurement (almost) directly after cleaning [4,6,8,[14][15][16]. We developed ATP thresholds for conducting an ATP measurement at a random point in time on a hospital ward, not knowing if items were used or cleaned that day.…”

Background: The objective of this study was to determine the level of environmental contamination in hospitals in the Dutch/Belgian border area, using ATP measurements. Design: A cross-sectional observational survey. Methods: Standardized ATP measurements were conducted in 9 hospitals on 32 hospital wards. Thirty pre-defined surfaces per hospital ward were measured with the 3 M Clean Trace NG luminometer. Results are displayed in relative light units (RLU). RLU > 1000 was considered as "not clean." Differences in RLU values were compared between countries, hospitals, fomite groups and medical specialties. Results: A total of 960 ATP measurements were performed, ranging from 60 up to 120 per hospital. The median RLU-value was 568 (range: 3-277,586) and 37.7% of the measurements were rated as not clean (RLU > 1000). There were significant differences between countries, hospitals and fomite groups. Conclusion: ATP measurements can be used as a more objective approach to determine the level of environmental contamination in hospitals. Significant differences in ATP levels were found between hospitals and between countries. Also, substantial differences were found between different fomite groups. These findings offer potential targets for improvement of cleanliness in healthcare facilities.

“…13 Other studies have recommended an RLU threshold for cleanliness at 250-500 RLU, however this threshold is intended for measurement (almost) directly after cleaning. 4,6,8,14,15,16 We developed ATP thresholds for conducting an ATP measurement at a random point in time on a hospital ward, not knowing if items were used or cleaned that day. The goal of this study was to visualize the environmental contamination independent from the time of cleaning and to determine the environmental contamination to which a patient is exposed in the hospital.…”
