Abstract:
Objective:To investigate the features, changing trend, and rules of pneumoconiosis in Jiangsu Province, China, as well as the health status of patients with pneumoconiosis.Methods:From July to October 2019, the patients with pneumoconiosis, reported up to the end of 2018 in Jiangsu Province, were enrolled as respondents, and follow-up and retrospective investigation were performed. A total of 24405 patients with pneumoconiosis were investigated, and related data were collected from the monitoring system of cause of death for residents, pneumoconiosis network reporting system, occupational disease diagnosis institution, management institutions for the reporting of occupational diseases, and related residents' committee or village committee. The patients with pneumoconiosis, who had been reported, were followed up by telephone or on-site visit to obtain the information on their conditions. A descriptive analysis was performed for age of onset, working years, sex, category of industry, type of pneumoconiosis, annual disease onset, geographic distribution, and medical security.Results:Among the 24405 patients, a male/female ratio was 16.81∶1. Of all 24405 patients, 15948 (65.35%) had stage 1 pneumoconiosis, 5289 (21.67%) had stage 2 pneumoconiosis, and 1637 (6.71%) had stage 3 pneumoconiosis. The mean working years for dust exposure was 16.25±9.95 years for all patients, and the mean working years for dust exposure was 15.80±9.95 years for patients with stage 1 pneumoconiosis, 17.82±9.80 years for patients with stage 2 pneumoconiosis, and 16.31±9.90 years for patients with stage 3 pneumoconiosis. The highest number of cases of pneumoconiosis was reported in Wuxi (5744 cases, accounting for 23.54%) , followed by Zhenjiang (4160 cases, accounting for 17.05%) , Xuzhou (3851 cases, accounting for 15.78%) , Yancheng (3340 cases, accounting for 13.69%) , and Suzhou (2948 cases, accounting for 12.08%) . Major types of pneumoconiosis included silicosis (15392 cases, accounting for 63.07%) and coal workers' pneumoconiosis (5253 cases, accounting for 21.52%) . In this survey, 21115 completed follow-up, among whom 15924 survived and 5191 died, 15924 patients with pneumoconiosis survived, among whom 7461 (46.85%) had an age of ≥70 years and 2515 (15.79%) were exposed to dust for 5-9 years. The industries involved were mainly coal mining and washing industry (5687 cases, accounting for 35.71%) and public management, social security, and social organization (3349 cases, accounting for 21.03%) ; in terms of security, 7999 patients (50.23%) were covered by occupational injury insurance, 946 (5.94%) were compensated by employers, 4537 (28.49%) were covered by basic medical insurance for urban and rural residents, 1590 (9.98%) were covered by critical illness insurance, and 5458 (34.28%) were covered by other types of social security, such as medical assistance and poverty relief.Conclusion:Silicosis and coal worker's pneumoconiosis are the key points for the prevention and treatment of pneumoconiosis in Jiangsu Province, and supervision should be strengthened for industries and regions with serious dust hazards.
