OBJECTIVE
to assess the correlation among the ATP-bioluminescence assay, visual inspection and microbiological culture in monitoring the efficiency of cleaning and disinfection (C&D) of high-touch clinical surfaces (HTCS) in a walk-in emergency care unit.
METHOD
a prospective and comparative study was carried out from March to June 2015, in which five HTCS were sampled before and after C&D by means of the three methods. The HTCS were considered dirty when dust, waste, humidity and stains were detected in visual inspection; when ≥2.5 colony forming units per cm2 were found in culture; when ≥5 relative light units per cm2 were found at the ATP-bioluminescence assay.
RESULTS
720 analyses were performed, 240 per method. The overall rates of clean surfaces per visual inspection, culture and ATP-bioluminescence assay were 8.3%, 20.8% and 44.2% before C&D, and 92.5%, 50% and 84.2% after C&D, respectively (p<0.001). There were only occasional statistically significant relationships between methods.
CONCLUSION
the methods did not present a good correlation, neither quantitative nor qualitatively.
目的
评估三磷酸腺苷生物发光法、目视检查和微生物培养在监测急诊留观病房高接触临床表面清洁与消毒（C&D）效果中的相关性。
方法
于2015年3月至6月进行了一项前瞻性对比研究，采用这三种方法在清洁与消毒前后对五个高接触临床表面进行采样。目视检查中若发现灰尘、废物、潮湿和污渍，则认为高接触临床表面不干净；培养中每平方厘米发现≥2.5个菌落形成单位则认为不干净；三磷酸腺苷生物发光法中每平方厘米发现≥5个相对光单位则认为不干净。
结果
共进行了720次分析，每种方法240次。清洁与消毒前，目视检查、培养和三磷酸腺苷生物发光法检测到的表面清洁率分别为8.3%、20.8%和44.2%，清洁与消毒后分别为92.5%、50%和84.2%（p<0.001）。各方法之间仅偶尔存在统计学显著相关性。
结论
这些方法在定量和定性方面均未呈现良好的相关性。
