全国医疗机构病区环境消毒现况调查与分析

Current situation of environmental disinfection in medical institutions in China

目的了解本国医疗机构环境消毒的实施情况,为《医疗机构消毒技术规范》WS/T 367—2012的贯彻落实与修订提供科学依据。方法采取多阶段分层抽样的方法,抽取全国6个省份共168所医疗机构,由其医疗机构感染管理专职人员调查填写,并网络上报其普通病区和重点部门空气与物体表面消毒方式、频次及消毒效果监测情况。结果共163所医疗机构参与调查,其中2所医疗机构未开设普通病区。75所(46.58%)医疗机构对普通病区进行空气消毒,其中42所(56.00%)医疗机构采用紫外线灯照射进行消毒,31所(41.33%)医疗机构只在终末或必要时消毒;98所(60.87%)医疗机构对普通病区物体表面定期进行消毒,其中94所(95.92%)医疗机构每天消毒1~2次;73所(45.34%)医疗机构对普通病区进行环境消毒效果监测,其中47所(64.38%)医疗机构每季度至少监测1次。141所(86.50%)医疗机构对重点部门空气进行消毒,其中122所(86.52%)每天消毒2次;163所(100%)医疗机构均对重点部门物体表面进行消毒,其中134所(82.21%)每天消毒≥2次;161所(98.77%)医疗机构定期对重点部门进行环境消毒效果监测,其中111所(68.94%)医疗机构为每季度监测1次。结论《医疗机构消毒技术规范》WS/T 367—2012的颁布促进了各级医疗机构环境清洁与消毒工作,但医疗机构对普通病区存在消毒与监测过度与不足并存的现象,需进一步改进。

Objective To understand the implementation of environmental disinfection in medical institutions(MIs)in China,provide scientific basis for the implementation and revision of Regulation of disinfection technique in healthcare settings(WS/T 367-2012).Methods By multi-stage stratified sampling method,168 MIs in 6 pro-vinces were selected,monitoring results of disinfection mode,frequency and efficacy of air and object surface in general wards and high risk departments were surveyed,filled and reported on internet by full-time staff of infection management in MIs.Results A total of 163 MIs participated in the survey,2 of which didn’t open general wards.75(46.58%)MIs disinfected air in general wards,42(56.00%)disinfected with ultraviolet light,31(41.33%)only performed terminal disinfection or disinfected when necessary,98(60.87%)regularly disinfected object surface in general wards,94(95.92%)disinfected once or twice a day;73(45.34%)MIs monitored the effect of environmental disinfection in general wards,47(64.38%)of which monitored at least once per quarter.141(86.50%)MIs disinfected air in high risk departments,122(86.52%)of which disinfected twice a day;163(100%)MIs disinfected object surface of high risk departments,134(82.21%)of which disinfected at least twice a day;161(98.77%)MIs regularly monitored the effect of environmental disinfection in high risk departments,111(68.94%)of which monitored once a quarter.Conclusion The issuing of Regulation of disinfection technique in healthcare settings(WS/T 367-2012)has promoted the environmental cleaning and disinfection in all levels of MIs,but the phenomenon of excessive and insufficient disinfection and monitoring of general wards exists in MIs,which needs further improvement.
