2022年某自治区职业卫生检测能力验证结果分析

Analysis of verification results of testing capacity on occupational health in an autonomous region in 2022

目的分析2022年某自治区疾病预防控制中心(简称疾控中心)和职业卫生技术服务机构(简称职服机构)职业卫生检测实验室间比对结果,评估某自治区各职业卫生检测实验室的检测能力和质量。方法采取指定的方法比对,依据定值赋值法判断,对参加比对的实验室的检测结果进行符合性判断。结果疾病预防控制中心和职服机构61家参比实验室提交检测项目244个,合格202个、合格率82.8%;职服机构合格率(91.6%)高于疾控中心(75.7%),差异有统计学意义(χ^(2)=10.720,P<0.05);综合评定合格30家、综合评定合格率49.2%,职服机构综合评定合格率(66.7%)高于疾控中心(35.3%),差异有统计学意义(χ^(2)=5.926,P<0.05),职服机构实验室综合检测能力高于疾控中心。结论某自治区参加比对的职业卫生实验室检测能力基本能满足职业卫生检测要求,应加强其检测能力。

Objective To compare the test results between the laboratory of the disease control and prevention of an autonomous region(CDC for short)and the laboratories of the occupational health vocational service agencies(vocational service agencies for short)in 2022,and evaluate the testing capacity and the quality of the laboratories for occupational health testing in the autonomous region.Methods The conformity of the test results of the participating laboratories was judged by specifying method and the fixed-value assignment method.Results There were 244 test items provided by the laboratory of CDC and other 61 laboratories of the occupational service agencies.202 items were qualified,with the qualified rate of 82.8%.The qualified rate was 91.6%in the occupational service agencies,higher than that of 75.7%in CDC,with statistical difference(χ^(2)=10.720,P<0.05).After comprehensive assessment,30 laboratories are qualified,with the qualified rate of 49.2%.The qualified rate of comprehensive assessment was 66.7%in the occupational service agencies,higher than that of 35.3%in CDC,with statistical difference(χ^(2)=5.926,P<0.05).The laboratory comprehensive testing ability of the occupational service agencies was higher than that of CDC.Conclusions The testing capacity of the occupational health testing laboratories which participate the comparison in the autonomous region basically meet the requirements of occupational health testing.The testing ability needs to be further improved.
