某医院病原微生物标本送检质量监测

Surveillance of Collection of Clinical Microbiological Specimensb

目的分析某医院临床病原微生物标本采集中存在的问题,为制定有效的干预措施,提高标本采集质量提供指导。方法由院感办、检验科和临床科室成员组成小组,对送检的1616份病原微生物标本质量进行监测,并对不合格送检标本的原因进行分析。结果 2013年1-12月微生物标本不合格率为12.8%,2014年1-12月微生物标本不合格率为4.7%;微生物标本质量监测中发现患者的认知度差、依从性低,不配合有效的采样方法;部分标本被污染、采集量不足、送检不及时、暂存不当等是造成病原微生物标本送检不合格的主要原因。结论该医院病原微生物标本送检标本质量尚存在一定问题,其原因主要与患者的认知度差及采样流程不规范有关。

Objective To analyze the existing problems with the collection of clinical microbiological specimens, and to find effective ways to improve the quality of specimen collection. Methods The quality ofmicrobiological specimenswas evaluated, the reasons for unqualified specimens were analyzed and corresponding countermeasures were proposed. Results There were many problems in the process of specimen collection, such as specimen contamination, inadequate amounts of collection, delayed in- spection, and improper temporary storage. After intervention, the failure rates of microbial specimens decreased obviously from 12.8% （between Jan 2013 and Dec 2013） to 4.7 % （ between Jan 2014 and Dee 2014）. Conclusion We need to improve the quality of specimens by perfecting specimen collection manuals, enhancing training on specimen collection, implementing the process control of specimen collection, and strengthening the ties between departments.
