In response to a request arising out of employee concerns over the medical surveillance program at the Chrysler Corporation Foundry (SIC-3321) located in Indianapolis, Indiana, an evaluation was made of chest radiographs evaluated by this program with specific concern directed to disagreement on the radiographic diagnosis of pneumoconiosis. The request was made by the Chrysler Corporation and the United Auto Workers National Joint Committee on Health and Safety. Three NIOSH certified B-readers independently interpreted a set of 78 systematically sampled posteroanterior (PA) chest radiographs from the system files. These interpretations were compared among themselves and with company interpretations. While none of the radiographs was deemed unreadable, 35 percent were classified as having poor technical quality. Only one film was found which had a profusion of small opacities, and the company had interpreted this film as positive. Overall, agreement on proportion of positive readings and agreement on individual films was as good between the company and B-readers as it was between any two of the individual B-readers. The author recommends, however, that in order to avoid future complaints of this nature, the company should use standard radiographic equipment and techniques, NIOSH certified B- readers, and current international classifications of radiographs for pneumoconioses in their medical surveillance program.
