临床生化检验室间质控三年结果的评价

Evaluation on results of external quality control in clinical biochemical trial

目的:对室间质量评价的得分情况进行统计学分析,总结室内质控和室间质量评价的经验,以便更好地为临床服务。方法:将卫生部室间质控标本与常规标本用全自动生化分析仪在同样条件下进行测试,将得到的2005～2007年6次临床生化室间质评结果进行统计。结果:2005～2007年,质控检测21项临床生化指标,变异指数得分(VIS)优良率由59.52%提高至88.09%,不及格率由28.57%降至0。结论:通过室间质控,发现不足,经过改进,提高检验结果的准确度保证,保证了检验质量。因而质量控制对于临床生化检验结果的质量保证非常重要,只有做好室内质控和室间质量评价,才能为临床提供准确的诊断、治疗和预后观察的依据。

Objective： Analyze the statistically data （scores） of external quality assessment and acquire experience from internal quality control and external quality assessment. Methods： By automatic biochemical analyser,21 clinical biochemical index of samples were measured. Results： From 2005 to 2007, 21 clinical biochemical index of samples were measured. Variability index scoring （VIS） merit rate increased from 59.52% to 88.09 %, the fail rate decreased from 28.57% to 0%. Conclusion： We found the defiviency by the quality control and made improvement, thus ensured the inspection quality, quality control is important to the results of the clinical laboratory quality assurance. By internal quality control and quality assessment, we can provide an accurate clinical diagnosis, treatment and prognosis.
