2010—2022年184所医疗机构胃镜与肠镜消毒效果监测数据分析

Surveillance data of disinfection efficacy for gastroscopes and enteroscopes in 184 medical institutions from 2010 to 2022

目的了解中国医疗机构胃镜和肠镜的消毒质量,为消化内镜的科学消毒提供指导。方法2010—2022年依托“全国医院消毒与感染控制监测”项目对中国30个省份184所医疗机构胃镜和肠镜的消毒工作进行调查,并对胃镜和肠镜的清洗消毒质量进行分析。结果2010—2022年,184所医疗机构共采集6421份消毒后内镜标本,包括4011份胃镜标本,2410份肠镜标本。2010—2022年,中国胃镜消毒合格率从87.6%上升至97.9%,肠镜消毒合格率从75.9%上升至95.4%。二级医疗机构内镜消毒的平均合格率低于三级医疗机构(87.5%VS 92.1%)。不同种类内镜消毒剂的消毒效果也存在差异,其中过氧乙酸的合格率最高(95.6%~95.7%),邻苯二甲醛次之(93.6%~95.0%),而酸性氧化电位水的合格率较低,仅为55.0%~85.0%。结论中国胃镜及肠镜的消毒质量持续改善,但仍需要加强日常消毒质量的监测。

Objective To evaluate the disinfection quality of gastroscopes and enteroscopes in medical institutions across China,and provide scientific guidance for the disinfection of digestive endoscopes.Methods From 2010 to 2022,relying on the“National Hospital Disinfection and Infection Control Surveillance”project,the disinfection status of gastroscopes and enteroscopes in 184 medical institutions in 30 provinces in China was investigated,clea-ning and disinfection quality of gastroscopes and enteroscopes was analyzed.Results From 2010 to 2022,a total of 6421 post-disinfection endoscope specimens were collected from 184 medical institutions,including 4011 gastroscope specimens and 2410 enteroscope specimens.From 2010 to 2022,the qualified rate of disinfection of gastroscopes and enteroscopes in China increased from 87.6% to 97.9% and 75.9% to 95.4%,respectively.The average qualified rate of disinfection of endoscopes in secondary medical institutions was lower than that in tertiary medical institutions(87.5%vs 92.1%).The disinfection efficacy of different kinds of endoscopic disinfectants was also different,among which the qualified rate of peracetic acid was the highest(95.6%-95.7%),followed by o-phthalaldehyde(93.6%-95.0%).The qualified rate of acidic electrolyzed-oxidizing water was low,only 55.0%-85.0%.Conclusion The disinfection quality of gastroscopes and enteroscopes in China has been continuously improved,and it is still necessary to strengthen the surveillance on daily disinfection quality.
