Epidemiological characteristics and survival analysis on patients with occupational pneumoconiosis in Zhejiang Province from 1987 to 2019

Abstract

ObjectiveTo evaluate risk factors affecting survival in patients diagnosed with pneumoconiosis and propose strategies to improve the quality of life in these patients.MethodsThe basic patient information was obtained from the pneumoconiosis report card. Disease types, regions, and industry distribution of pneumoconiosis were analyzed. The Kaplan-Meier survival curves and the Cox proportional risk regression model was used for survival analysis.ResultsA total of 13,812 patients were diagnosed with pneumoconiosis in Zhejiang province from 1987 to 2019. The overall survival rate at the end of life table analysis was 83%. Kaplan-Meier analyses showed that there were significant differences between survival curves depending on the stage of first diagnosis, age at first diagnosis, type of pneumoconiosis, industry, and duration of dust exposure (P < 0.05). The results of Cox proportional hazards regression analysis showed that pneumoconiosis stage of first diagnosis, age at first diagnosis, industry, and duration of dust exposure were risk factors affecting patient survival (P < 0.05).ConclusionsThe patients with high stage of pneumoconiosis at first diagnosis, older age, and long duration of dust exposure should be followed up and monitored as key population, and the industries with high incidence of pneumoconiosis such as mining and construction should be supervised as key industries.

Survival and disease burden analyses of occupational pneumoconiosis during 1958–2021 in Huangshi city, China: a retrospective cohort study

“…In terms of different types of pneumoconiosis, this study found no significant differences in the survival curves among the three categories, which is consistent with a study conducted in Jiangsu Province [ 12 ]. However, we did not observe statistically significant differences in survival among different stages of pneumoconiosis in this study, which is inconsistent with a previous study conducted in Zhejiang Province [ 18 ]. This discrepancy in findings may be attributable to the smaller number of stage III patients in our study and the relatively similar survival status between stage II and stage I patients.…”

“…Pneumoconiosis poses a serious threat to the health of workers and places a significant burden on society, affecting millions of workers worldwide who engage in hazardous occupations [ 18 ]. It is one of the common occupational diseases in China.…”

“…Disease burden of pneumoconiosis patients with different characteristics Coal workers' pneumoconiosis; DALY: Disability-Adjusted Life Year; YLD: Years lived with disability; YLL: Years of life lost due to premature mortality; a : Other types of pneumoconiosis include: graphite pneumoconiosis, carbon black pneumoconiosis, asbestosis, talc pneumoconiosis, pottery worker's pneumoconiosis, aluminosis, other pneumoconiosis, pneumoconiosis (unknown)study conducted in Zhejiang Province[18]. This discrepancy in findings may be attributable to the smaller number of stage III patients in our study and the relatively similar survival status between stage II and stage I patients.…”

Analysis of Prognosis, Survival Status, and Risk Factors of Occupational Pneumoconiosis Patients in Lanzhou Area

“…As workers age, lung ventilation function decreases significantly, and dust or debris from processed materials can be inhaled by workers. Long term work can lead to the occurrence of occupational pneumoconiosis [16][17] . The length of service exposed to dust is an independent risk factor for the occurrence of occupational pneumoconiosis.…”
