江苏省二级医院内镜消毒质量监测分析

Quality of Endoscopic Disinfection in Jiangsu Provincial Second Care Level Hospitals

目的监测全省二级医院内镜室日诊量情况与内镜清洗消毒效果,发现医院感染控制工作中的不足。方法对2008年第四季度-2009年第三季度内镜室情况与内镜监测数据进行回顾性分析,研究日诊量最高时"患者独占时间"与内镜消毒合格率之间的相关性。结果 6所二级医院共调查样本量72份,内镜监测合格率为90.27%,内镜携菌量最大数为1600 CFU/件;二级医院平均拥有4条内镜,日诊量最高例数平均为21例,工作时间平均为7.17 h;日诊量最高时,患者独占时间为(1.31±0.53)h,双变量相关性检验显示,患者独占时间与内镜合格率之间存在显著相关性(r=0.860,P=0.028)。结论患者独占时间与内镜清洗消毒质量紧密相关,可作为预测内镜清洗消毒合格率的重要参考依据。

OBJECTIVE To understand the effect of the cleaning and disinfection of endoscopes in endoscopic rooms to discover the insufficiency of controlling nosocomial infection.METHODS The biological monitoring of the endoscopes and the situation of endoscopic rooms from fourth quarter 2008 to third quarter 2009 were performed in a retrospective way.The qualified rate of bacterial culture of endoscopes in all provincial second care level hospitals and their relation with the patients′ exclusive time on a high level of consultation were analyzed.RESULTS Totally 72 samples were collected from 6 second care level hospitals.The qualified rate of bacterial culture of endoscopes was 90.27%.The maximal bacteria-carrying capacity of endoscopes was 1600 CFU/per piece.The average quantity of endoscopes and the average working time were 4 pieces and 7.17 hours in each second care level hospitals,respectively.The average max treatment volume was 21.The patients′ exclusive time was 1.31±0.53 hours on a high level of consultation.Bivariate correlation tests indicated that significant correlation exists between the patients′ exclusive time and the qualified rate of bacterial culture of endoscopes（r=0.860,P=0.028）.CONCLUSION The patients′ exclusive time is closely related to the quality of endoscopic disinfection,which can be an important reference to forecast the qualified rate of the endoscopes.
