Abstract:

U.S. Navy Asbestos Medical Surveillance Program B-reading reports were analyzed for variability in identifying pneumoconiosis in 278,944 chest radiographs done from 1990 to 2004 using commercial database and statistical software. Reported presence of pneumoconiosis by 33 B-readers ranged from 1.85 to 32.28%. The reported presence of parenchymal abnormalities ranged from 0.11 to 15.07%; increased profusion (to 1/0 or greater) of small parenchymal opacities ranged from 0.10 to 17.70%; presence of large opacities ranged from 0.00 to 0.67%; and presence of pleural abnormalities ranged from 1.08 to 23.93%. Ranges appear to be decreasing slightly as rates of abnormal findings are diminishing. Differences between U.S. East Coast, West Coast, and midcontinent were not statistically significant.
