ATP荧光检测法在医院感染管理中的应用

Application of ATP fluorescence detection method in healthcareassociated infection management

摘要:

目的探讨ATP荧光检测法用于医院感染管理现场监测督导的效果。方法某院2015年各季度采用生物荧光检测仪对医务人员手、环境物体表面，以及清洁工具的污染情况进行检测，及时反馈检测结果，并提出改进措施。结果共检测1 294份标本，合格率为62.75%。医务人员手、环境物体表面，以及清洁工具的检测合格率分别从第一季度的54.35%、50.30%和60.26%，提高至第四季度的76.42%、64.80%和79.52%，经趋势χ2检验，差异均有统计学意义（均P＜0.05）。医务人员手、环境物体表面，以及清洁工具对应的相对光单位值（RLU）中位数分别为20.00、85.00和35.00。 结论ATP荧光检测法用于现场督导，作为评价清洁效果的手段，可以促进手卫生和环境清洁度的持续质量改进。

Abstract:

ObjectiveTo explore the effect of ATP fluorescence detection on onsite monitoring and supervision of healthcareassociated infection management . MethodsATP bioluminescence analyzer was used to detect the contamination status of hands of health care workers(HCWs), the object surfaces, and the cleaning tools in all quarters of 2015, the detection results were timely given feedback, and improvement measures were put forward. ResultsA total of 1 294 specimens were detected, the overall qualified rate was 62.75%. The qualified rates of hands of HCWs, object surfaces, and cleaning tools increased from 54.35%, 50.30%, and 60.26% in the first quarter to 76.42%, 64.80%, and 79.52% in the fourth quarter respectively，tendency chisquare test showed that difference was statistically significant (all P＜0.05). The median of relative light unit (RLU) of hands of HCWs, object surfaces, and cleaning tools were 20.00, 85.00, and 35.00, respectively. ConclusionATP fluorescence detection for onsite monitoring and supervision for cleaning and disinfection effect can promote the continuous quality improvement of hand hygiene and environmental cleanliness.
