All suspected cases of silicosis are evaluated by a multidisciplinary team. Based on the final diagnosis, the compensation is decided.Nearly 5000 workers were screened, and 729 appeared before the medical board. Of these 729, 465 were having silicosis, and their data are presented here (data of 7 patients were missing). All workers were males. The mean age was 44.54 ± 9.6 years, and the mean exposure (work experience) was 17.25 ± 6.7 years. Most of the workers were between the age of 40 and 50 years and had exposure for 10-20 years. Chest radiography examination showed that progressive massive fibrosis (large size type C opacities) was the most common type of presentation (23%). Smaller opacities (p, q, r and s, t, u) were combined for further analysis, given their similar prognostic significance. It was found that age and experience both had a linear and significant correlation with the severity of lung involvement.RESULTSNearly 5000 workers were screened, and 729 appeared before the medical board.
