The physicians who are using ILO classification should have appropriate education and experience including regular digital chest X-ray and certificated by the boards of pulmonary, occupational medicine or radiology and / or should be competent in the assessment of pneumoconiosis radiographs as reader B by NIOSH.9
Usually underexposure leads for a higher; overexposure leads for a lower category in ILO classification. The factors for the differences in the interpretation of films between the observers depends on different levels of medical education, difficulty in getting previous radiographs and clinical data and even the conditions of reading rooms.
For my indicator I use the ILO [International Labor Organization] standard, the ILO formula and the ILO classification
. We have a Lebanese specificity, but this specificity should be highlighted through the scientific work rather than through what I want to highlight.
([dagger]) A "B Reader" is a physician certified by NIOSH as demonstrating proficiency in the use of ILO classification
of radiographs of pneumoconiosis.
No evidence of pneumoconiosis was noted by CT scan and chest x-ray films according to ILO classification
. Bronchoscopy showed near-total occlusion of orifice of RML bronchus, which showed markedly inflamed mucosa with anthracotic pigmentation.
Of the 113 survey participants who had ever blasted or worked as helpers, eight (7%) had chest radiographs that were classified as being consistent with pneumoconiosis; all eight were classified as major profusion category one or greater (ILO classification
[is greater than or equal to] 1/0).
