ABSTRACT
Objective To analyze the distribution, survival conditions, and medical support of newly diagnosed occupational pneumoconiosis (hereinafter referred to as pneumoconiosis) patients in Zhangdian District, Zibo City. Methods A total of 1 189 newly diagnosed pneumoconiosis patients in Zhangdian District from 1956 to 2019 were selected as the study subjects using retrospective method. Data of their age of onset, years of occupational exposure, category of working industry, type of pneumoconiosis, and status of medical support was collected and analyzed. Results The median and the 25th-75th percentiles [M (P25, P75)] of the age of onset were 51.8 (45.5, 56.1) years, and the mortality was 37.0%. The majority of pneumoconiosis cases were silicosis (45.2%) and coal workers' pneumoconiosis (39.8%). The highest prevalence of pneumoconiosis was in the coal mining and washing industry (42.4%), followed by manufacturing (33.4%). Pneumoconiosis patients in stage Ⅰ,Ⅱ, and Ⅲ accounted for 89.1%, 8.7%, and 2.2%, respectively. The M (P25, P75) of the length of work exposed to dust were 24.1 (16.5, 29.9) years.The higher stage of pneumoconiosis the shorter of the length of work exposed to dust among these pneumoconiosis patients(all P<0.05). The overall survival rate, the 5-year survival rate and the 10-year survival rate of these pneumoconiosis patients were 63.0%, 92.3% and 85.9%, respectively. Among the 749 surviving cases, 60.8% were aged 60.0 to <80.0 years. In terms of social security, 100.0% surviving cases enjoyed basic medical insurance, meanwhile, 96.1% and 81.8% patients were covered by major medical insurances and occupational injury insurances, respectively. The M (P25, P75) of age at death were 73.1 (64.0, 77.1) years. The main causes of death were respiratory diseases (59.3%) and malignant tumors (20.4%). Conclusion The prevalent types of pneumoconiosis in Zhangdian District, Zibo City, are coal workers' pneumoconiosis and silicosis. Medical support and assistance are relatively limited. The pneumoconiosis prevention and control focus should be on silicosis and coal workers' pneumoconiosis, particularly in the manufacturing industry.
