abstract={<b>Objective</b>: This study aimed to examine the sensitivity and specificity of occupational health doctors (OHDs)¡¯ reading of early-stage pneumoconiosis radiographs. <b>Materials and Methods</b>: A screening test was applied, and 33 OHDs consented to participate in the study. There were atotal of 67 chest radiographs, which consisted of normal and early-stage pneumoconiosis film. The cut-point for disease was set at profusion0/1 and 1/0. Mean sensitivity and specificity for small opacity detection were analyzed. <b>Results</b>: The median sensitivity of ILO profusion of 0/1 or above was 88% (IQR 10.3), and the median sensitivity of film with a 1/0 cutoff pointwas slightly higher at90% (IQR 10.3).The average specificity for ILO profusion of 0/1 or above was 43.3% (SD21.1). Upon increasing the cut-point at profusion1/0, the average specificity increased to 47.0% (SD 20.9). <b>Conclusion</b>: This study showed that occupational health doctors were able to interpret chest radiographs of workers with early-stage pneumoconiosis. This indicates that the development of OHDs¡¯ chest X-ray reading skillsis valuable in order to improve the national pneumoconiosis surveillance system.},
