【摘要】 目的通过分析不合格标本的数量和不合格标本的原因,以此作为提高实验室分析前质量管理持续性改进的控制指标之一。方法对住院患者各种常规标本中不合格标本数和不合格率,分析不合格标本发生的主要原因。结果 2008、2009年不合格标本总数分别为803份、727份,分别占2008、2009年标本总数的0.71%、0.47%。按照拒收原因作分类统计,其中标本采集不合格为932份(60.9%),标本信息不合格为485份(31.7%),标本运送不合格为77份(5.0%),其他原因36份(2.4%),标本不合格率2008、2009年比较差异有统计学意义(P<0.05)。结论采用一系列改进措施,有助于保证分析前的质量控制,为临床提供全面而准确的评价。更多还原

【Abstract】 Objective Through statistical analysis of unsatisfactory specimens of the number and causes of failed samples,aimed at reducing the number of failed samples,as a pre-analysis to improve laboratory quality management,continual improvements in the control of one of the indicators.Methods According to the laboratory quality management requires that we developed an analysis of the former specimen collection,transportation,receipt,rejection and a series of requirements,clinical doctors and nurses for professional training,adhere to the matching sample system,we had statistical analysis of kinds of specimens in 2008~2009,the failure of conventional specimen number and the reasons for unsatisfactory specimens.Results In 2008 and 2009 the total number of unsatisfactory samples were respectively 803 and 727,accounting for 0.71% total annual sample and 0.47%,According to statistics of the reasons for rejection,in which 1 530 samples were unqualified failure for the 932 samples were collected,accounting for 60.9% of the total number of unsatisfactory specimens;samples failed to information 485,accounting for 31.7%;sample delivery is not meet the requirements of 77,accounting for 5.0%,36 were disqualified for other reasons,accounting for 2.4%,Failure rate of 2009 samples and 2008 samples compared the failure rate decreased significantly.Conclusion Adopted a series of improvements,help to ensure quality control before analysis,to provide comprehensive and accurate clinical evaluation.更多还原
