Abstract:
Objective To investigate the characteristics of 136 patients with occupational diseases,to summarize key techniques used in field investigation,and to provide a scientific basis for the development of standard operating procedures for field investigation of occupational disease diagnosis.Methods Field investigation and routine data analysis were performed to analyze the cases diagnosed by Guangdong Provincial Hospital for Occupational Disease Prevention and Treatment from January 2009 to December 2014.Results A total of 136 cases of occupational diseases were diagnosed by Guangdong Provincial Hospital for Occupational Disease Prevention and Treatment from 2009 to 2014,and there were 66 cases of leukemia,18 cases of suspected occupational benzene poisoning,12 cases of suspected occupational hand-arm vibration disease,and 11 cases of suspected pneumoconiosis.Of all these patients,41.91％ were engaged in at least three types of work,70.59％ were exposed to at least three types of chemicals,25.74％ experienced changes in technical processes and chemicals,and 47.06％ had disputes on the chemicals they were exposed to during verification by both parties.Occupational hazard factors were detected.Most samples (358) were used to measure benzene concentration in workplace air,among which 11.7％ had a benzene concentration of ＞6.00 mg/m3 (exceeding standard),13.41％ had a benzene concentration of 3.26～6.00 mg/m3,75.42％ had a benzene concentration of＜ 0.03 to ＜3.25 mg/m3.The samples of suspected occupational hand-arm vibration disease,suspected pneumoconiosis,and suspected occupational noise-induced hearing loss had high over-standard rates (100％,93.8％,and 83.3％,respectively).Conclusion Field investigation of occupational disease diagnosis reveals large numbers of cases of leukemia,suspected occupational benzene poisoning,suspected occupational handarm vibration disease,and suspected pneumoconiosis.The key aspects of field investigation include confirmation of the history of occupational exposure,identification of occupational hazard factors,confirmation of the changes in technical processes and chemicals,detection of occupational hazard factors,sampling and analysis of raw materials,and epidemiological investigation of workers with the same type of work.
