Comparison of network report and actual detection of suspected occupational diseases among lead exposed workers in Jiangsu Province from 2016 to 2018

Abstract

Objective: To analyze and compare the detection level and actual detection of suspected occupational diseases of lead exposed workers in the network report of occupational disease and occupational health information monitoring system, so as to provide a basis for formulating and improving relevant laws and regulations on occupational disease monitoring in the future. Methods: From January 2016 to December 2018, the network report occupational health examination data of lead exposed workers in Jiangsu Province were selected, the network report detection rate of suspected occupational diseases of lead exposed workers was counted and compared with the actual detection rate judged in the early stage, and the distribution characteristics of the network report detection rate of different years, regions and occupational health examination institutions and the reasons for the difference with the actual detection rate were analyzed. Results: Network report detection rate of suspected occupational disease in Jiangsu Province from 2016 to 2018 (0.042%, 30/71810) was significantly lower than the actual detection rate of 1.12% (805/71810) , and the difference was statistically significant (χ(2)=723.518, P<0.01) . The network report detection rates of suspected occupational chronic lead poisoning showed an increasing trend year by year, and the difference were statistically significant (χ(2)(trend)=7.627, P<0.01) . All the 30 network report cases were male, and 28 cases (93.33%) were from small and medium-sized enterprises. Among the 805 cases of suspected occupational chronic lead poisoning, 689 cases (85.59%) came from small and medium-sized enterprises. The three cities with more cases were Huai'an 222 cases (27.58%) , Suzhou 208 cases (25.84%) and Changzhou 138 cases (17.14%) . Compared with the actual detection, the number of network reports in Yangzhou accounted for 85.29% (29/34) of the actual detection from 2016 to 2018, that in Suqian accounted for 10.00% (1/10) , and that in other prefecture level cities was 0. From 2016 to 2018, 46.22% (33191/71810) of the occupational health examinations of lead exposed workers were undertaken by Centers for Disease Control and prevention at all levels (referred to as "CDC") . The 30 suspected cases of occupational chronic lead poisoning reported network came from CDC, accounting for 4.89% (30/614) of the actual detection, and the rest were 0. Conclusion: There are great differences between the network report and the actual detection rate of suspected occupational chronic lead poisoning among lead exposed workers, mainly due to the differences in the judgment level of suspected occupational diseases in different regions, the nature of institutions and the level of professional technicians.
