摘　　要：目的以6西格玛(σ)管理方法评价凝血检验项目分析质量。方法分别选取本室2015年4-6月份全自动凝血分析仪Sysmex CS2000i的室内质控结果与本室2014-2015年参加卫生部临床检验中心的室间质评结果,计算凝血酶原时间(PT)、活化部分凝血活酶时间(APTT)、纤维蛋白原(FIB)三个项目的偏倚和变异系数(CV)水平,并依据允许总误差,计算σ值,评价本实验室凝血检验项目的分析性能;计算质量目标指数(QGI),查找原因,改进后于下个月重新评价。结果经过改进后,本室凝血三项6σ结果均达到质量目标,说明本室所采取的预防措施积极有效。结论 6σ质量管理有助于不断提高临床实验室质量水平,是质量控制的有效管理工具。Objective Assessing the coagulation analytes with six sigma （σ） management , in order to improve quality performance. Methods Data of the Internal quality control from April to June in 2015 and the External Quality Assessment in which my laboratory participated between 2014 and 2015 were collected. The bias and imprecision （CV） was calculated for prothrombin time （PT）, activated partial thromboplastin time （APTT） and fibrinogen （FIB）. According to the allowed total errors （TEa）, sigma （σ） was calculated and the quality performance of the laboratory blood coagulation analytes was evaluated. The quality target index （QGI） was calculated to find the main reason, improve and re-evaluate in next month. Results After the improvements, the results of the 6σ value were reached quality goals, indicated the resolutions were helpful. Conclusion 6σquality helps to improve the quality of clinical laboratory level consistency; it was an effective tool for quality control.
