Objective:To analyze the situation of hospitalized migrant workers with pneumoconiosis in Hunan Province, and to provide reference for the prevention and treatment of pneumoconiosis.Methods:In July 2019, the data of pneumoconiosis migrant workers hospitalized in Hunan Prevention and Treatment Institute for Occupational Diseases from February 2017 to February 2019 were retrospectively analyzed, and the general situation, region distribution, diagnosis and complications were analyzed.Results:From February 2017 to February 2019, a total of 6344 migrant workers with pneumoconiosis were treated, mainly distributed in Zhuzhou city (1283 cases, 20.22%) , Yiyang city (1048 cases, 16.52%) and Loudi city (783 cases, 12.34%) . Coal worker's pneumoconiosis (4242 cases, 66.87%) and silicosis (2089 cases, 32.93%) were the main types of pneumoconiosis. Among them, 1433 cases (22.59%) were in stage I, 1318 cases (20.77%) were in stage II, and 3593 cases (56.64%) were in stage III. The age of the patients was mainly between 41-60 years old (4584 cases, 72.26%) . 3869 patients (60.99%) had complications and chronic obstructive pulmonary disease (3046 cases, 48.01%) and pulmonary infection (1703 cases, 26.84%) were the most common complications. There were 1510 patients (23.80%) who had two or more complications. There were significant differences in the number of complications among patients with different diagnosis stages and age stages (χ 2=764.43, 90.24, P<0.01) . Conclusion:Coal worker's pneumoconiosis and silicosis are the main types of pneumoconiosis among hospitalized migrant workers in Hunan Province, and most patients were in stage III. Older patients with higher pneumoconiosis stage have more complications, early diagnosis and treatment should be taken.
