The objective of this study was to determine the level of environmental contamination in hospitals in the Dutch/Belgian border area, using ATP measurements. A cross-sectional observational survey. 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. 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. 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.

ATP测量是测量荷兰/比利时边境地区9家医院环境污染的一种客观方法。

这项研究的目的是使用ATP测量来确定荷兰/比利时边境地区医院的环境污染水平。横断面观察调查。在9家医院的32个病房中进行了标准化的ATP测量。每个医院病房用30 M Clean Trace NG光度计测量30个预定义的表面。结果以相对光单位（RLU）显示。RLU> 1000被认为是“不干净”。比较了国家，医院，团体和医学专业之间的RLU值差异。总共进行了960次ATP测量，每家医院的测量范围为60到120。RLU的中值为568（范围：3–277,586），其中37.7％的测量结果为不干净（RLU> 1000）。各国之间存在重大差异，医院和团体。ATP测量可用作确定医院环境污染程度的更客观的方法。医院之间和国家之间发现ATP水平存在显着差异。同样，在不同的fomite组之间发现了实质性的差异。这些发现为改善医疗机构的清洁度提供了潜在的目标。
