目的了解四川省第五次结核病流行病抽样调查中X线胸片诊断水平现状。方法抽取全省11个国家级流调点拍摄的15 187张胸片中的异常胸片314张,分别由省级阅片小组和国家级阅片小组进行复核,计算出3组阅读同一胸片结果的一致性Kappa值(K)和比较阅片诊断类型中的差异性。结果县级与省级、国家级的阅片结果一致性K值分别为0.173和0.206;省级与国家级的阅片结果一致性K值为0.613。在阅片诊断类型上,差异最大的为疑似肺结核和非结核的诊断。结论国家级与省级判定结果的一致性K值较高,国家级与县级、省级与县级判定结果一致性K值均较低。
Objective To understand the status quo of diagnosis of X-ray in the fifth sampling survey of tuberculosis in Sichuan province. Methods A total of 314 anomalous chest radiographs of 15 187 chest radiographs were taken from 11 national-level epidemic-point spots in the province, which were reviewed respectively by the provincial reading group and the national reading group, and three groups of reading chest radiographs Consensus of results The Kappa values (K) and the differences in the diagnostic type of the comparison readings. Results The concordance K values of county-level, provincial-level and national-level reading results were 0.173 and 0.206, respectively. The concordance K between provincial and national reading results was 0.613. In the diagnostic type of reading, the biggest difference is suspected tuberculosis and non-tuberculosis diagnosis. Conclusion The concordance between national and provincial judgments has a high value of K, and the concordance K between national and county-level, provincial and county-level judgments is low.
