Effectiveness of hospital disinfection and experience learnt from 11 years of surveillance

This survey was designed to assess the sanitation status of hospitals and the compliance of hospital staff to disinfection strategies within the past 11 years.A total of 199 provincial affiliated tertiary or secondary public hospitals from 2007 to 2017 were investigated and seven critical categories,namely indoor air,work surface,hand hygiene,ultraviolet(UV)irradiation intensity,use of disinfectants,sterilization of medical items,and effects of steam sterilizer,were monitored.The average qualified rates were(94.74±3.54)%(810/855),(97.25±1.65)%(1876/1929),(87.57±4.60)%(2508/2864),(95.00±4.50)%(1196/1259),and(98.76±1.14)%(1599/1619)for indoor air,work surface,hand hygiene,UV irradiation intensity,and sterilization of medical items,respectively.In terms of other categories,few samples were not qualified:3/1575 for use of disinfectants and 1/243 for effects of steam sterilizer.The hospital disinfection monitoring and supervision program effectively improved the effectiveness of disinfection.Routine monitoring and supervision must be conducted to ensure a safe hospital treatment environment.

北京市托幼单位消毒工作现状调查

１９９３～１９９５年，经细菌检测，北京托幼单位在全年中以第三季度物体表面与室内空气卫生合格率较低，分别为７０．２９％与７０．９３％。应用中消毒液合格率（７０．８３％）亦较低。物体表面卫生合格率，市区、近郊区与远郊县分别为８４．２５％、８３．２４％与８０．９０％，手卫生合格率分别为８０．０９％、７８．１６％与７６．９９％。

巴盟地区医疗单位消毒工作质量调查

为了解巴盟地区各级医疗单位消毒工作质量,采用平板沉降法和棉拭子采样法对消毒后的室内空气、物体表面、医护人员手及使用中的消毒剂进行了检测。结果,手术室、产房空气细菌超标率为71.21％(47/66);医务人员手和物体表面细菌污染超标率波动在10％～100％;使用中消毒剂污染超标率波动在6％～33％。加强管理后消毒工作质量逐年提高,但空气卫生质量仍未得到有效控制。

临沂市托幼单位消毒工作质量调查

为了解临沂市托幼单位消毒工作质量，１９９７～２０００年对托幼单位室内空气用平板沉降采样，对人员手与物体表面用棉拭涂抹采样，作细菌检测。结果，室内空气细菌总数超标（＞５００ ｃｆｕ／ｍ３）率为９０．８％（３６７／４０４）。人员手与物体表面以细菌总数＜１０ｃｆｕ／ｃｍ２，并且不得检出致病菌与沙门菌为合格，在肥皂、流水洗手前、后合格率分别为１５．６％和８９．０％；以含有效氯５００ｍｇ／Ｌ溶液消毒前、后，物体表面合格率分别为１８．２％和９０．６％。说明加强对消毒工作管理与落实消毒制度的重要。

西宁市某医院卫生消毒质量调查

目的了解西宁市某医院卫生消毒质量,以便改进提高。方法通过现场采样和检测方法,以该医院眼科手术室等为目标进行了消毒质量监测。结果在2010年全年从该医院眼科共采样310份,平均总合格率为95.2%。在各种监测对象中,室内空气卫生质量合格率为94.5%;物体表面卫生合格率为97.9%;医护人员手合格率为96.3%。结论该医院眼科手术室和换药室等场所室内空气及其他监测对象卫生消毒质量合格率较高,对少数合格率较低部位需要有针对性地加强管理。
