摘要:

目的 应用六西格玛(6σ)方法评价河北省17家三级甲等医院血细胞分析项目室内质量控制(IQC)室间比对性能,探讨IQC室间比对新方法,促进质量改进。方法 收集河北省17家三级甲等医院血细胞分析项目[白细胞(WBC)计数、红细胞(RBC)计数、血红蛋白(Hb)、血小板(PLT)计数] IQC室间比对数据,统计其x、变异系数(CV)、偏移(Bias)、西格玛(σ)值和质量目标指数(QGI)。结果 当使用我国卫生行业标准WS/T 406—2012《临床血液学检验常规项目分析质量要求》中的允许总误差(TEa)时,WBC计数、RBC计数、Hb、PLT计数中值和高值2个水平性能≥6σ的实验室分别占52.94%、47.06%,17.65%、17.65%,35.30%、23.53%和52.94%、58.82%;4≤σ<6的实验室分别占35.30%、47.06%,29.41%、29.41%,47.05%、47.06%和35.30%、35.30%。结论 河北省17家三级甲等医院血细胞分析项目检验性能优良。6σ方法可提供统一而简单的评价标准,用于临床实验室IQC室间比对更加简便、直观。

Abstract:

Objective To use six sigma(6σ) for evaluating the performance of blood cell analysis internal quality control(IQC)inter-laboratory comparison among 17 laboratories from Grade 3 Class A hospitals in Hebei,and to improve the quality of blood cell analysis. Methods The data of IQC inter-laboratory comparison among 17 laboratories from Grade 3 Class A hospitals in Hebei were collected,and the determination items included white blood cell(WBC) count,red blood cell(RBC) count,hemoglobin(Hb) and platelet (PLT) count,and coefficients of variation(CV),biases(Bias),sigma(σ) values and quality goal indices(QGI) were calculated. Results Using WS/T 406—2012 as standard for allowable total error(TEa),the laboratories with the performance of WBC count,RBC count,Hb and PLT count with 2 levels (middle level and high level)≥6σ accounted for 52.94% and 47.06%,17.65% and 17.65%,35.30% and 23.53%,52.94% and 58.82%,and those with 4≤σ<6 accounted for 35.30% and 47.06%,29.41% and 29.41%,47.05% and 47.06%,35.30% and 35.30%,respectively. Conclusions The performance of blood cell analysis IQC inter-laboratory comparison among 17 laboratories is good,and 6σ is a unified and simple method for IQC.
