对反馈的32例生化检验结果误差原因的调查分析

Analysis of 32 Errors in the Feedback of Biochemistry Test Results

目的 加强全面及全过程质量控制 ,为临床提供准确、可靠的实验诊断依据。方法 用常规检测方法 ,对工作中有误差反馈的生化检验结果 ,重新取标本检测或对标本复检 ,调查其引起误差的原因。结果 实验前、实验中、实验后误差分别在实验误差中占 6 9%、2 9%、3% ;由实验室各方面原因引起的误差占实验误差的 6 2 .5 % ,由临床方面原因引起的误差占实验误差的 37.5 % ;由临床方面送检不规范引起的误差占实验前误差的 5 4 .5 % ,由实验室方面引起的误差占实验前误差的 4 5 .5 %。结论 误差可以出现在实验过程的不同阶段 ,即使完全的客观指标 (全自动生化分析仪 ) ,在实验中阶段仍可出现误差 ,临床送检不规范及实验室标本处理不当是引起实验误差的最主要的原因 ,因此强化全面及全程质量控制概念 ,对医生、护士、检验者同样重要。

Objective In order to enhance quality control generally,and to offer accurate and reliable experimental results for clinical diagnosis.Method For biochemistry test results with error feedback,the exemplar was taken again or rechecked using routine methods,and error reasons were analyzed.Results The error rate before ,during and after tests were 69%,29%,3% respectively; the error aroused by lab was accounted for 62.5% of test error, by clinic 37.5%; the error aroused by clinics was 54.5% of pretest error,and by lab 45.5%.Conclusions The error could occur in different experimental phases ,even if there were whole objective indices in labs.The uppermost reasons causing errors were that samples were informally sent by clinic and that samples were disposed improperly, so for doctors,nurses and verifier,strengthening the quantity control in the whole course was equally important.
