上海市检验结果互认定量项目室间质量评价结果分析

Analysis on the results of external quality assessment of mutual recognition quantitative items in Shanghai

目的分析上海市检验结果互认定量项目的检测性能,为医疗机构间检验结果互认工作的推进提供参考。方法收集2020年上海市临床检验中心(SCCL)58个检验结果互认定量项目第2次室间质量评价(EQA)参评实验室回报结果,计算各项目EQA成绩和基于5种来源允许总误差(TEa)的西格玛(σ)度量。结果有802家临床实验室回报结果,抗凝血酶原项目EQA合格率为92.59%,有18个项目EQA合格率为100.00%;分别有32.54%的公立医疗机构和67.46%的非公立医疗机构临床实验室成绩不合格。基于SCCL的TEa标准,有39个(67.24%)项目的σ度量>3;基于Tea的最大值,有51个(87.93%)项目的σ度量>3,有14个(24.14%)项目的σ度量>6;基于Eea的最小值,有12个(20.69%)项目的σ度量>3。结论上海市各医疗机构临床实验室检验结果互认定量项目总体一致性较好,但部分检验项目不同医疗机构临床实验室检测结果存在差异,应引起重视。

Objective To analyze the performance of mutual recognition quantitative items in Shanghai,in order to promote the mutual recognition of determination results in medical institutions.Methods The results of 58 mutual recognition quantitative items of clinical laboratories in Shanghai Center for Clinical Laboratory(SCCL)from the second External Quality Assessment(EQA)in 2020 were selected to calculate the EQA scores and the sigma(σ)metrics from allowable total error(TEa)sources.Results A total of 802 clinical laboratories of medical institutions reported the results of 58 mutual recognition quantitative items.EQA pass rates ranged from 92.59%(antithrombin)to 100.00%(18 items).The failed rates of medical institutions were 32.54%in public hospitals and 67.46%in non-medical institution clinical laboratories.Taking the value of TEa from SCCL,39(67.24%)items had aσmetrics>3.Taking the maximum value of TEa,51(87.93%)items had aσmetrics>3,and 14(24.14%)items had aσmetrics>6.Taking the minimum value of TEa,12(20.69%)items had aσmetrics>3.Conclusions The mutual recognition quantitative items in Shanghai have good consistency among clinical laboratories.However,there are differences in determination results between clinical laboratories in different medical institutions for some items,which should be paid attention to.
