摘要目的:总结分析省级卫生机构参加个人剂量检测比对的结果，探究能力比对对省级卫生机构检测能力的提升作用。方法:汇总2009—2022年省级疾控中心、职业病防治院在全国(2009—2020年)/国家级(2021—2022年)个人剂量检测能力比对中取得的结果，按照《2022中国卫生健康统计年鉴》东、中、西部地区的分区方式分区，对不同地区比对结果进行分析比较。结果:共有来自30个省、自治区及直辖市的24家省级疾控中心和14家省级职业病防治院参加2009—2022年的13次能力比对，参加机构的数量由2009年的26家增加到2022年的37家。3个地区省级卫生机构比对结果的合格率共37次保持在85%以上，28次达到100%，3个地区合格率与优秀率分别有9次和5次均高于同期全国(2009—2020年)/国家级(2021—2022年)全部参比机构的整体水平。中部地区省级卫生机构在9次比对中优秀率相较另两个地区更高。结论:随着比对标准不断提高，各地区省级卫生机构保持着稳定较强的检测能力。全国个人剂量检测能力比对有效地提升了省级卫生机构的检测能力和质量控制水平，多家机构将能力比对列为常态化工作。

abstractsObjective:To summarize and analyze the results of the individual dose intercomparison in which province-level health institutions participating, and explore the role of ability intercomparison in improving the detection capabilities of province-level health institutions.Methods:From 2009 to 2022, the results obtained by the province-level CDCs and occupational prevention and control institutions in the individual dose intercomparison countrywide for time periods of 2009—2020 and 2021—2022 were summarized. The intercomparison results were analyzed and compared for three regions of east, central and west China divided according to the method from China Health Statistics Yearbook 2022.Results:A total of 24 province-level CDCs and 14 occupational prevention and control institutions countrywide participated in the ability intercomparison from 2009—2022 for 13 times. Number of participating institutions increased from 26 in 2009 to 37 in 2022. The qualified rates of the intercomparison results among the province-level health institutions in the three regions were maintained at higher than 85% for 37 times and 100% for 28 times. The pass rate and excellent rate of the three regions were higher than the overall level at whole country level (2009-2020) and national level (2021-2022) in the same period for 9 and 5 times, respectively. The excellent rate of province-level health institutions in central region were higher than that of the other two regions in 9 intercomparisons.Conclusions:With the improvement of the intercomparison standard, the province-level health institutions in various regions have maintained a relatively stable and high detection capability. The ability intercomparison effectively improve the detection ability and the quality control of the province-level health organizations. Many province-level agencies have listed the ability intercomparison as the regular work.
