2002-2008年惠州市区医疗机构消毒质量监测

Quality of Disinfection in Hospitals in Huizhou Urban Districts from 2002 to 2008

目的了解广东省惠州市区医疗机构消毒质量,探讨消毒监测中存在的问题,加强医院感染监控力度。方法采用普查的方法,按照统一的技术方案对辖区内医疗机构进行消毒质量监测,收集2002-2008年惠州市疾病预防控制中心对医疗机构进行消毒监测的数据,并用SPSS统计软件进行分析。结果2002-2008年惠州市区医疗机构消毒监测样品总数依次为3270、2399、3861、5206、5054、5267、4584份,合格率依次为87.40%、93.25%、89.48%、90.34%、87.73%、87.98%、91.19%,总合格率为89.41%。二级以上、一级和社会医疗机构消毒监测样品合格率分别为91.13%、88.05%、87.74%,三者差异有统计学意义(χ2=90.20,P<0.01)。监测样品中病房物体表面合格率最高(97.07%),最低为空气中细菌含量(70.42%)。结论二级以下的医疗机构消毒质量较低,因此,一级和社会医疗机构是消毒监测工作的重点。

Objective To investigate the sanitary quality of hospitals in Huizhou,Guangdong province,and to discuss the existing problems during the monitoring process in order to improve the efficiency of disinfection and strengthen the control of nosocomial infections.Methods Data concerning the sanitary conditions of hospitals were obtained from the Center for Disease Control and Prevention of Huizhou between 2002 and 2008.The collected information was analyzed using SPSS software.Results A total of 3270（2002）,2399（2003）,3861（2004）,5206（2005）, 5054 （2006）, 5267 （2007） and 4584 （2008） records were collected and analyzed. The eligible rates were 87.40% （2002）,93.25% （2003）,89.48% （2004）,90.34% （2005）,87.73% （2006）,87.98% （2007） and 91.19% （2008）. The total eligible rate was 89.41%. The eligible rate meeting the sterilization standard in the second level hospitals, the first level hospitals and the social medical institutions was 91.13%,88.05% and 87.74%,respectively. The difference in the eligible rate was significant in these three groups of hospital（x2=90.20 ,P〈0.01 ）. Microbiological analysis revealed that 97.07% of the object surface in the sickroom and 70.42% of the air sample passed the quality test. Conclusion Medical institutions under the second level hospitals had a lower sanitary quality than the other hospitals. There was a variation in eligible rates among hospitals. Both of the first level hospitals and social medical institutions should be closely monitored in the future.
