[目的]探讨精神病专科医院检验不合格标本的原因,以提高检验分析前质量保证与控制水平。[方法]对2007～2009年检验不合格标本按不同类型、原因和年份进行统计分析。[结果]统计3年标本不合格率为5.88%。血液和培养标本的不合格率较大,分别为6.10%和4.83%,尿液和粪便标本的不合格率为4.36%和3.45%。不合格标本前5项原因是溶血、脂血、标本量不符、标本凝固、标本放置时间过久,不合格比率高达97.41%。连续3年各年份不合格标本间不合格率差异无统计学意义(P﹥0.05)。[结论]精神病专科医院有必要通过采取各种有效方法和措施来加强检验分析前质量保证和控制水平以提高标本采集质量。
[Objective] To investigate the reason why non-qualified specimens were inspected by psychiatric hospitals to improve quality assurance and control before testing and analysis. [Method] The statistical analysis of different types, causes and years of unqualified samples from 2007 to 2009 was conducted. [Results] The 3-year statistical sample failed rate was 5.88%. The unqualified rates of blood and cultured specimens were 6.10% and 4.83% respectively, and the unacceptability rates of urine and stool specimens were 4.36% and 3.45%. The first five causes of unqualified specimens were hemolysis, lipids and blood, the amount of specimens did not match, the specimen was solidified and the specimen was placed too long, the unqualified rate was as high as 97.41%. There was no significant difference in the unqualified rate of unqualified samples in each year for three consecutive years (P> 0.05). [Conclusion] It is necessary for psychiatric hospitals to strengthen pre-analysis quality assurance and control by adopting various effective methods and measures to improve the quality of specimen collection.
