![]() ![]() ![]() NIOSH has employed B Readers in many epidemiologic and other research studies for nearly 30 years, as have many other organizations. The B Reader Program aims to ensure competency in radiographic reading by evaluating the ability of readers to classify a test set of radiographs, thereby creating and maintaining a pool of qualified readers having the skills and ability to provide accurate and precise ILO classifications.ī Readers, through their demonstrated proficiency in classifying radiographs of the pneumoconioses, are appropriate choices for research, surveillance, and worker monitoring programs and activities. ![]() The original intent of the B Reader Program still exists, but B Readers are also now involved with epidemiologic evaluation, surveillance, and worker monitoring programs involving many types of pneumoconioses. This included epidemiologic research on coal workers’ pneumoconiosis and the compensation of coal miners with pneumoconiosis under programs processed by government agencies (Morgan 1979). The B Reader examination was initially developed to identify physicians qualified to serve in national pneumoconiosis programs directed at coal miners and others who suffer from dust-related illness. The NIOSH B Reader Program began in 1974, although it was not until 1978 that the B reader examination was given extensively (Attfield 1992). ![]() As a consequence, NIOSH concluded that a proficiency program was needed to provide a pool of qualified readers. However, it was found that readers, despite employing the classification scheme, still disagreed with each other and with themselves to an excessive degree (Felson 1973). The principle intent of the standards was to achieve uniformity in assessing pneumoconiosis across readers. In 1949, the International Labour Office (ILO) promulgated standards for systematically describing and recording radiographic appearances of certain abnormalities caused by the inhalation of dusts. ![]()
