The 60-film set was developed by experts (Expert Group) for examining 8 indices: sensitivity (X₁) and specificity (X₂) for pneumoconiosis, sensitivity(X₃) and specificity for (X₄) large opacities, sensitivity (X₅) and specificity (X₆) for pleural plaque, profusion increment consistency for small opacities (X₇), and shape differentiation for small opacities (X₈) of physicians’ reading skills on pneumoconiosis X-ray according to ILO 2000 Classification. The aim of this study was to assess the appropriateness of the exam film set for evaluating physicians’ reading skills. 29 physicians (A1-Group) and 24 physicians (A2-Group) attended the 1st and 2nd “Asian Intensive Reader of Pneumoconioses” (AIR Pneumo) training course, respectively, and 22 physicians (B-Group) attended Brazilian training course. After training, they took examination of reading 60-film exam set. The examinees’ reading results in terms of 8 indices were compared between the examinee groups and the Expert Group by parametric unpaired t -test. The Examinee Group consisting of A1-Group, A2-Group and B-Group was inferior to the Expert Group in all indices. There was no significant difference for X₇ of A1-Group, X₇ and X₈ of A2-Group ( p >0.05) compared with the Expert Group. There was a significant difference in X₈ at p <0.05 between A1-Group and A2-Group, in X₃ at p <0.05 between A1-Group and B-Group, in both X₁ and in X₃ at p <0.05 between A2-Group and B-Group. Accordingly, the 60-film set providing 8 indices designed might be a good method for evaluation of the physicians’ reading proficiency at different training settings.
