Abstract Objective To investigate the epidemiological characteristics of suspected cases with occupational diseases and analyze the quality of occupational diseases report in Huzhou City from 2016 to 2020, so as to provide insights into supervision and early warning of occupational diseases. Methods The epidemiological data pertaining to suspected cases with occupational diseases reported in Huzhou City from 2016 to 2020 were retrieved from the Occupational Disease and Health Risk Factors Monitoring Information System of China Disease Prevention and Control Information System, including gender, age, type of job, industry category, enterprise size and diagnosis. The percentages of identification, diagnosis and definitive diagnosis were calculated, and the distribution and diagnosis of suspected cases with occupational diseases were descriptively analyzed among different regions, industry categories and enterprise sizes. Results A total of 264 398 people underwent occupational health examinations in Huzhou City from 2016 to 2020, and 322 suspected cases with occupational diseases were detected (12.18/104), including 179 cases with suspected pneumoconiosis (55.59%), 78 cases with suspected occupational ear, nose, throat and oral diseases (24.22%), 54 cases with suspected occupational poisoning (16.77%), 6 cases with suspected occupational skin diseases (1.86%), 3 cases with suspected occupational diseases caused by physical factors (0.93%) and 2 cases with other suspected respiratory diseases (0.62%). The 322 cases with suspected occupational diseases included 290 men (90.06%) and 32 women (9.94%), and had a mean age of (53.28±9.20) years. A total of 207 cases underwent occupational diseases diagnosis (64.29%), and 155 cases were definitively diagnosed with occupational diseases (74.88%). Among different counties (districts) in Huzhou City, the highest number of suspected cases with occupational diseases was reported in Changxing County (101 cases, 31.37%), with a diagnostic rate of 88.12%, and among all enterprises, the highest number of suspected cases with occupational diseases was reported in small enterprises (220 cases, 68.32%), with a diagnostic rate of 68.64%, while among all industry categories, the highest number of suspected cases with occupational diseases was reported in manufacture industry (228 cases, 70.81%), with a diagnostic rate of 56.14%. In addition, there was no suspected case with occupational diseases detected in agriculture, forestry, animal husbandry, fishery, wholesale/retail trade industry, or public administration, social security or social organizations. Conclusion Pneumoconiosis was the predominant type of suspected occupational diseases in Huzhou City from 2016 to 2020, and a low diagnostic rate was found. Improved supervision of occupational diseases control is strongly recommended among small enterprises to standardize the reporting system of suspected occupational diseases.
