摘要:

目的 参照国际最新规范《职业性尘肺病的诊断》(GBZ70⁃2015)的尘肺病影像诊断分期标准,回顾性分析影像医师诊断尘肺病影像学分期的一致性、个体间一致性及原始报告诊断的可靠性,为提高尘肺病影像学分期诊断的准确率提供依据。方法 邀请 3 名不同年资的尘肺病影像诊断医师R1、R2 R3(低、中、高)在尘肺诊断专用工作站对980例尘肺患者进行独立双盲阅片,并做出分期,记为0期、Ⅰ期、Ⅱ期、Ⅲ期,由 3 名医师共同阅片达成一致的分期为相对金标准,记为Major,收集各病例原始报告分类,记为 Report。参照 2016 5 1日实施的《职业性尘肺病的诊断》(GBZ70⁃2015)对尘肺病进行影像学分期诊断,记录阅片结果,进行数据整理及统计分析。结果 不同年资医师在尘肺病影像学分期的结果显示低年资医师与相对金标准的一致性中等(Kappa = 0.745),中、高年资医师与相对金标准的一致性较好(Kappa = 0.836、0.896),而原始报告的准确率偏低,一致性较差(Kappa = 0.583),三名医师的一致性较好(总体 Kappa = 0.765)。结论 不同年资阅片医师在进行尘肺病影像学分期方面存在一定差异,中、高年资医师的诊断一致性优于低年资医师,做出的分期结果不同。本研究在排除了外部因素干扰后发现阅片医师之间的差异性主要来自于Ⅰ期、Ⅱ期判断的差异,原始报告对尘肺分类评估的准确性有限。

Abstract:

Objective The aim of this study was to retrospectively analyze the consistency of imaging staging of pneumoconiosis diagnosed by imaging physicians and the reliability of original report diagnosis according to the latest international standard“diagnosis of Occupational Pneumoconiosis”(GBZ70⁃2015),so as to provide basis for improving the accuracy of imaging staging diagnosis of pneumoconiosis. Methods three pneumoconiosis imaging diagnostic physicians with different seniority,R1,R2,R3(low,medium and high)were invited to read the films independently and double blindly on the special workstation for pneumoconiosis diagnosis,and the stages were recorded as stage 0,stageⅠ,stageⅡ and stageⅢ. The three physicians read the films together to reach the relative gold standard,which was recorded as Major,to collect the original report classification of each case and recorded as Report. According to the diagnosis of Occupational Pneumoconiosis(GBZ70⁃2015)implemented on May 1,2016,the imaging stages of pneumoconiosis were diagnosed,the results of film reading were recorded and the data were collated and statistically analyzed. Results The results of imaging staging of pneumoconiosis by different seniority doctors showed that the consistency between low seniority physicians and relative gold standard was moderate(Kappa = 0.745),and that between middle and senior seniority doctors and relative gold standard was better(Kappa = 0.836,0.896),but the accuracy of original report was low,the consistency was poor(Kappa = 0.583),and the consistency of three doctors was good(overall Kappa=0.765). Conclusion there are some differ⁃ ences in imaging staging of pneumoconiosis among different seniority doctors. The diagnostic consistency of middle and senior doctors is better than that of low seniority doctors ,and the staging is different. In this study ,after excluding the interference of external factors,it was found that the difference among film ⁃ reading doctors mainly came from the difference between stage Ⅰ and stage Ⅱ judgment,and the accuracy of the original report on the classification and evaluation of pneumoconiosis was limited.
