Objective: To understand the epidemiological characteristics of suspected occupational diseases cases, and to track the subsequent diagnosis of suspected cases in Hubei Province from 2020 to 2021, and to provide theoretical basis for the supervision of suspected occupational diseases. Methods: In April 2022, the data of suspected occupational diseases cases and occupational diseases in Hubei Province from 2020 to 2021 were collected by the Occupational Diseases and Health Risk Factors Information Surveillance System. The distribution and diagnosis of suspected occupational diseases cases were analyzed. We investigated undiagnosed suspected occupational diseases by telephone. Results: From 2020 to 2021, a total of 1872 cases of suspected occupational diseases in 6 categories and 18 species were reported in Hubei Province. The top three suspected occupational diseases were suspected occupational noise deafness (36.75%, 688/1872), suspected coal worker's pneumoconiosis (33.07%, 619/1872) and suspected silicosis (20.99%, 393/1872). The diagnosis rate of suspected occupational diseases was 33.60% (629/1872). The rate of confirmed diagnosis was 63.59% (400/629). The diagnosis rate (26.86%, 456/1698) and rate of confirmed diagnosis (55.48%, 253/456) of suspected occupational diseases detected by occupational health examination were the lowest. The diagnosis rate of suspected occupational diseases detected by comprehensive medical institutions and private medical institutions were lower than disease prevention and control institutions and occupational disease prevention center (P<0.05). The main reasons for not entering the diagnostic procedure included that workers were not informed that they were diagnosed as suspected occupational diseases (31.55%, 124/393), workers were unwilling to apply for occupational disease diagnosis (18.56%, 73/393), and some workers planned to apply for diagnosis but had not yet applied (10.69%, 42/393) . Conclusion: Occupational noise deafness, coal worker's pneumoconiosis and silicosis are the main diseases of suspected occupational diseases in Hubei Province. In order to increase the diagnosis rate and confirmed diagnosis rate of suspected occupational diseases, it is suggested to strengthen management and supervision from the aspects of case management, information warning and worker notification.
目的： 了解湖北省2020至2021年疑似职业病病例的流行病学特征，并追踪疑似病例的后续诊断情况，为疑似职业病监管提供数据依据。 方法： 于2022年4月，收集2020至2021年"职业病与健康危害因素监测信息系统"中湖北省报告的疑似职业病和职业病病例，分析疑似职业病病例的分布及确诊情况，并电话随访未诊断的疑似职业病患者。 结果： 2020至2021年湖北省共报告疑似职业病6大类18种1 872例。疑似职业病排在前三位的病种为疑似职业性噪声聋（占36.75%，688/1 872）、疑似煤工尘肺（占33.07%，619/1 872）和疑似矽肺（20.99%，393/1 872）。2020至2021年报告的疑似职业病诊断率为33.60%（629/1 872），确诊率为63.59%（400/629）；通过职业健康检查检出的疑似职业病诊断率（26.86%，456/1 698）和确诊率（55.48%，253/456）均为最低，由综合医疗机构、民营体检机构检出的疑似职业病诊断率低于疾病预防控制机构和职业病防治院（P<0.05）。未进入诊断程序的主要原因是劳动者未被告知自己是疑似职业病（占31.55%，124/393）、劳动者不愿申请职业病诊断（占18.56%，73/393）、计划申请诊断但还未进行申请（占10.69%，42/393）。 结论： 职业性噪声聋、煤工尘肺和矽肺是湖北省疑似职业病主要病种。应加强病例管理、信息化预警、劳动者告知以提高职业病诊断率和确诊率。.
