对驻京医疗单位进行医院感染及消毒的监督监测

Supervision of Nosocomial Infection and Sterilization in Medical Institutions Located in Beijing

目的对驻京7所医疗单位医院感染诸环节进行监督监测,了解掌握情况,制定有效的管理措施。方法采用现场监督、测试、采样及实验室检测相结合的方法,对所采集的含氯消毒剂、戊二醛消毒剂分别进行有效成分含量的测定。结果被检查的7所医疗单位,呼吸道感染仍然占首位;各医院口腔科加强了对牙钻等器械的消毒,但对胃镜室的内镜等器械消毒情况的检查中发现,多数医疗单位没有严格按照国家卫生部有关清洗操作规定执行,使用中消毒剂有效浓度合格率为71.43%;多酶液采样合格率为57.14%。结论建立重点科室的目标性监测,进一步加强医院感染的监督,尤其是胃镜室器械消毒情况的检测,从而有效控制医院感染的发生。

OBJECTIVE Nosocomial infection and relevant aspects were investigated in 7 medical institutions located in Beijing in order to master the general information, rule out the efficient measures and make the correct decision for control of infectious diseases in time. METHODS A series methods including the fieldwork supervision, testing, collecting samples and laboratory analysis were employed in this study. In addition, the disinfeetors containing the chloride and glutaraldehyde were quantitatively analyzed for the efficient components. RESULTS In the seven medical institutions examined, incidence of upper and lower respiratory infections was the leading one among the nosocomial infections such as respiratory, digestive, mouth infections and so on. The dental instruments were found to be well sterilized in all hospitals, but the endoscopic appliances in most hospitals were not seriously sanitized according to national regulations and requirements. In practice, 71.43% of disinfectants were with effective concentration and 57.14% of multienzyme liquid sampled were up to standard. CONCLUSIONS The further supervision should be addressed to target the major instruments with serious problems like the endoscopic appliances to avoid the nosocomial infections.
