ABSTRACT
Objective@#o explore the problems encountered in the application of GBZ/T 237-2011 edition of "Diagnosis of Chronic Obstructive Pulmonary Disease Caused by Occupational Stimulating Chemicals" , and to provide reference for the revision of the new standard.@*Methods@#Delphi expert survey method was used to consult experts on the reasonableness of six primary indicators (scope of application, diagnostic principles, diagnostic indicators, treatment principles, diagnostic grading, appendix A) and their corresponding secondary indicators in the Diagnosis of Chronic Obstructive Pulmonary Disease (COPD) caused by Occupational Stimulant Chemicals.@*Results@#The results of the first round of Delphi method showed that the reasonable mean of the diagnostic criteria about long-term occupational history, smoking history and clinical diagnostic criteria was less than 7, and the coefficient of variation was greater than 0.25, indicating that the experts disagreed with the scope of application of the original criteria; the average of smoking history and 3-year working age were 1.78 and 3.43 (less than 7) respectively, which indicated that the experts agreed that the two diagnostic indexes were not conducive to the practical work of occupational disease clinicians; among the diagnostic indicators, smoking history and smoking volume were taken into account in a comprehensive way, and the average values were 7.61 and 7.61 (greater than 7) , respectively. the coefficient of variation was less than 0.25, indicating that the experts had concentrated their opinions and agreed that such indicators could be considered into the diagnostic index system.@*Conclusion@#"Diagnosis of Chronic Obstructive Pulmonary Disease Caused by Occupational Stimulating Chemicals" should be improved by expanding the scope of occupational irritant gases. Smoking problems can be considered in combination with clinical practice, and occupational exposure history can be considered to reduce appropriately.
