目的 评价疾控机构盐碘检测能力,为碘缺乏病防治提供可靠的检测数据.方法 对2013年辽宁省疾控机构114个盐碘实验室外质控考核结果进行评价分析.通过Z比分值图形对检测结果的复现水平和误差类型予以分析,通过Youden图寻找检测结果需复核的离群值,盐碘检测采用《制盐工业通用试验方法碘的测定》(GB/T 13025.7-2012).结果 根据Z比分值单样评价,111个实验室结果合格,合格率为97.4％(111/114),3个实验室检测结果不合格,不合格率为2.6％(3/114);双样评价结果中,112个实验室结果合格,合格率为98.2％(112/114),有2个实验室检测结果不合格,不合格率为1.8％(2/114).Youden图显示,共计有5个点在椭圆外,占全部实验室的4.4％(5/114),提示这5个实验室的检测结果有可能离群,需要做进一步的复核.结论 利用图形法分析考核数据可直观显示考核结果,有助于查找针对性的改进措施,持续提高检测能力.

Objective To evaluate the detection capability for salt iodine test by using graphic method,and to provide reliable detection data for prevention of iodine deficiency disorders.Methods The examination results of external quality assessment for disease control mechanism in Liaoning Province in 2013 were analyzed by using standard Z score and Youden plot.The level of reproduction and type of error were analyzed by Z score sequence diagram in order to find the outliers and results need to be reviewed by the Youden plot.Salt iodine was detected by the general test method in salt industry for determination of iodine (GB/T 13025.7-2012).Results According to single sample evaluation of the Z score,111 laboratories were qualified,the qualified rate was 97.4％ (111/114).Three labs were not qualified,unqualified rate was 2.6％ (3/114).According to double sample evaluation of the Z score,112 laboratories were qualified,the qualified rate was 98.2％ (112/114).Two laboratories were not qualified,unqualified rate was 1.8％ (2/114).According to the Youden plot,5 laboratories were possible outliers with results need to be reviewed.Conclusion Statistical graphic method has displayed the examination results directly,which is helpful in searching targeted improvements,and improving the detection capability.
