Analysis the causes and countermeasures of unqualified microbiological samples in public health

目的分析公共卫生中微生物检验标本不合格的原因及对策。方法选取2017年9月~2018年9月我疾控中心进行微生物检验的120例标本作为研究对象,标本来源包括空气、水质、公共卫生用具、一次性消毒餐具等。分析公共卫生中微生物检验标本不合格类型及原因,并在该基础上提供相应对策。结果120例微生物检验标本中不合格率为13.33%(16/120),合格率为86.67%(104/120)。16例微生物检验标本不合格类型包括医疗机构消毒效果检测标本、宾馆卫生微生物检测标本、游泳池卫生检测标本、饭店卫生微生物检测标本。16例微生物检验标本不合格原因包括外部环境不卫生、外观被损坏、检测结果不准确、检验程序不规范及原材料不合格。结论根据微生物检验标本不合格的原因制定相应的措施有利于提高微生物检验结果的准确性,对公共卫生工作具有重要的指导意义。
