Abstract:
Objective To explore the impact factors of misjudge of pneumoconiosis stage based on GBZ70-2015 criteria.Methods Sixty-five case of pneumoconiosis were retrospectively enrolled.Chest high-resolution CT were independently analyzed by one associate chief physician,one attending physician and one resident physician,respectively.The stage of pneumoconiosis was judged,and the inter-observer consistency was observed.Taken the results of 5 experts using Delphi method as gold standard,the impact factors of misjudge of pneumoconiosis stage were analyzed.Results Among 65 cases,there were 42 cases of stage 1,16 cases of stage 2 and 7 cases of stage 3 pneumoconiosis.The inter-observer consistency of pneumoconiosis stage was relatively high(Kappa=0.653),of stage 3 pneumoconiosis was the best(Kappa=0.803),followed by stage 1(Kappa=0.661),while of stage 2 was the lowest(Kappa=0.518).Radiologist lack experience(OR=4.872),the lesions mainly located in the posterior upper area of lungs(OR=2.317),the present of r-type small shadows(OR=3.105)and high CT pulmonary emphysema index(OR=1.214)were all independent impact factors of misjudge of pneumoconiosis stage(all P＜0.05).Conclusion Both the experience of radiologist and lesions'heterogeneity were main impact factors of misjudge of pneumoconiosis stage based on GBZ70-2015 criteria.
