Abstract
Posterior/anterior chest X-rays from silica (14808607) exposed mine workers and factory workers originally interpreted under the 1963 Chinese Roentgenodiagnostic Criteria for pneumoconioses were reinterpreted according to the 1986 criteria. There were 1,936 chest films which were independently read by three of a panel of 11 radiologists. Afterwards, three readers interpreted the films together (consensus readings). A comparison of old and new interpretations was conducted for 1,914 films. There was a crude agreement for the whole cohort of 57.4% and crude agreement within one step of 92.5%. The old readings were slightly higher than the new interpretations. Several possible reasons were cited for the differences noted between the older and the new radiographic interpretations. These reasons included the two different classifications used, the availability to the original readers of old X-rays and clinical data, reading biases, deterioration of films over time, and the different algorithms used to determine the final interpretation. In this study, virtually all of the films examined were thought to be of satisfactory quality by the new readers. The authors conclude that old interpretations are in substantial agreement with the current criteria for determining pneumoconiosis as demonstrated by the new readings, and that epidemiologic dose response studies can be based on data from the old readings.
