Abstract:
Objective:To analyze the incidence characteristics of occupational chronic benzene poisoning under two diagnostic criteria.Methods:In March 2020, 126 patients who were divided into the old criteria group (74 cases) and the new criteria group (52 cases) were retrospectively analyzed. These patients were diagnosed with occupational chronic benzene poisoning, and were diagnosed in our hospital during the period of January 2009 to December 2019. The gender composition, age of onset, years of benzene exposure, industry distribution, work type, benzene concentration in working environment and diagnostic grade of the two groups of patients were analyzed and compared. The follow-up of 22 benzene poisoning observation subjects under the old criteria were retrospectively analyzed.Results:There were no statistically significant differences in gender composition, age of onset, years of benzene exposure, industry distribution and work type between the old criteria group and the new criteria group ( P>0.05) . In the old criteria group and the new criteria group, 41.9% (31/74) and 17.3% (9/52) of the patients' workplace benzene concentration exceeded the maximum allowable concentration, respectively. The composition of different benzene concentration in the workplace between the two groups showed statistically significant ( P<0.05) . In the old criteria group, the proportion of mild poisoning (79.7%, 59/74) was the majority, while in the new criteria group, the proportion of moderate and severe poisoning (51.9%, 27/52) were the majority, and there was statistically significance in the composition ratio of diagnostic grade between the two groups ( P<0.05) . Under the old criteria, after folow-up of 22 cases of benzene poisoning observation subjects, we observed that 8 cases (36.4%) progressed to the level of chronic benzene poisoning. Conclusion:The revision of diagnostic criteria for benzene poisoning may affect the composition of diagnosis classification. Based on the rights and interests of workers, formulating more complete diagnostic criteria and system policies will be more conducive to the development of occupational benzene poisoning prevention and control.
