ATP生物荧光检测法对重症医学科环境清洁质量的干预效果

目的了解ATP生物荧光检测法对重症医学科(ICU)环境清洁质量的干预效果。方法2013年12月—2014年2月对某院ICU物体表面进行基线检测，然后采用ATP生物荧光检测法对ICU物体表面进行检测并进行干预，评价干预后环境清洁质量。结果基线调查共采样627份，合格384份，合格率61.2%，其中床栏头端、电话按键、门把手、电脑鼠标相对光单位（RLU）中位数＞300。干预前、中、后ICU物体表面清洁合格率分别为61.2%、76.6%、90.0%（χ2=142.23，P＜0.001）;干预后ICU工作环境、主要仪器设备、其他医疗器具清洁合格率分别为85.5%、98.3%、92.6%，均高于干预前（分别为48.8%、84.4%、69.1%）(均P＜0.05)。结论ATP生物荧光法能简便、快捷的检测消毒效果，有助于ICU及时有效地干预，提高环境清洁合格率。

Intervention efficacy of ATP bioluminescence assay in environmental hygiene quality in an intensive care unit

ObjectiveTo evaluate the intervention efficacy of ATP bioluminescence assay in environmental hygiene quality in an intensive care unit (ICU).MethodsFrom December 2013 to February 2014, the baseline status of object surfaces in the ICU of a hospital was detected, then ATP bioluminescence assay was adopted to detect and intervene ICU object surfaces, environmental hygiene quality was evaluated.ResultsIn the baseline survey, a total of 627 object surfaces were monitored，qualified rate was 61.2%(n=384). The median of relative light unit (RLU) of head of bedrails, telephone keyboards, doorknobs, and computer mice were all > 300. Before,during,and after intervention, qualified rates of object surfaces were 61.2%, 76.6%, and 90.0% respectively （χ2=142.23，P＜0.001）; after intervention, qualified rate of ICU working environment, main instruments and equipments, and other medical devices were all higher than before intervention (85.5% vs 48.8%, 98.3% vs 84.4%, 92.6% vs 69.1%，all P＜0.05).ConclusionATP bioluminescence assay can easily and quickly detect disinfection efficacy, it is helpful for timely and effective intervention in ICU, and improving the qualified rate of environmental hygiene.
