2011年203个性病医疗卫生机构淋球菌分离鉴定室间质评结果分析

Tests for the identification and isolation of Neis seria gonorrhoeae： a nationwide external quality assessment in 203 medical and healthcare facilities providing sexually transmitted disease services in 2011

目的探讨各级性病医疗卫生机构分离鉴定淋球菌检测质量，分析存在的问题。方法质评样本采用冻干法，集中统一发放到203个性病医疗卫生机构，由中国疾病预防控制中心性病控制中心对回报结果进行统计分析，并将考评的结果反馈给各参评单位。结果共对252家单位发放质评样本，结果的总回报率为80．56％（203／252），总合格率为80．30％（163／203），平均成绩为87．14分；回报结果与预期结果一致的有109家，占总参评数的53．69％（109／203）；5株质评样本结果鉴定的正确率：2株纯淋球菌的正确率分别为82．76％（168／203）、87．68％（178／203），2株非淋球菌（干燥奈瑟菌、粪肠球菌）的正确率分别为86．21％（175／203）、96．06％（195／203），而含淋球菌的混合菌正确率只有69．46％（141／203o结论各级性病卫生机构之间淋球菌分离鉴定的能力存在一定的差距。

Objective To make a nationwide external quality assessment of tests for isolation and identifi- cation of N. gonorrhoeae in medical and heahhcare facilities at different levels, and to analyze current problems. Methods Lyophilized quality control samples were uniformly delivered to 252 medical and heahhcare facilities providing sexually transmitted disease （STD） services at different levels. Test results were analyzed by the National Center for STD Control, China Center for Disease Control and Prevention, and evaluation results were fed hack to participating laboratories. Results Finally, test results were received from 203 （80.56%） facilities. The compre- hensive score averaged at 87.14, and facilities achieving a comprehensive score of 80 or greater amounted to 80.30% （163/203）. The coincidence rate was 53.69% （109/203） for all of the 5 quality control samples, 82.76% （168/203） and 87.68% （178/203） respectively for two quality control samples containing only N. gono^hoeae, 86.21% （175/203） and 96.06% （195/203） respectively for a sample containing Neissen＇a sicca and a sample containing Enterococcus faecalis, 69.46% （141/203）for a sample containing different species of Neisseria. Conclusion The external quality assessment reveals a disparity in the capability to isolate and identify Neisser/a among medical and healthcare facilities providing STD services at different levels.
