[Study on survival analysis and influencing factors of pneumoconiosis patients in Guangzhou].
Objective: To analyze the survival of pneumoconiosis patients in Guangzhou from 1958 to 2018, explore the factors affecting the survival of pneumoconiosis, and provide scientific basis for formulating the guidelines and policies for treatment and assistance of pneumoconiosis. Methods: From July 2019 to January 2020, 1194 cases of occupational pneumoconiosis patients diagnosed by institutions qualified for pneumoconiosis diagnosis in Guangzhou from June 1, 1958 to December 31, 2018 were studied. Excluding 258 patients who lacked survival data, 936 patients were included in the pneumoconiosis survival analysis. Life table method was used to estimate the survival rate, Kaplan-Meier method was used to draw the survival curve, log-rank test was used to compare the groups, and Cox proportional risk regression model was used to analyze the influencing factors of survival. Results: The 10, 20 and 30 years cumulative survival rates of pneumoconiosis patients in Guangzhou were 62.8%, 35.2% and 15.4%, respectively. The median survival time was 19.4 years. log-rank test showed that there were statistically significant differences in the survival curves of pneumoconiosis patients between group without tuberculosis and group with tuberculosis (P<0.001), and there were statistically significant differences among different stages and categories of pneumoconiosis (P<0.001). Age of exposure to dust (HR=1.03, 95%CI: 1.01-1.05), age of diagnosis (HR=1.02, 95%CI: 1.00-1.04), combined pulmonary tuberculosis (HR=1.46, 95%CI: 1.18-1.81), stage of pneumoconiosis (stage Ⅲ vs. stage Ⅰ, HR=2.26, 95%CI: 1.47-3.48) and categories of pneumoconiosis (fibrogenic mineral dust pneumoconiosis and metallogenic pneumoconiosis, HR=2.45, 95% CI: 1.61-3.74; non-fibrogenic mineral pneumoconiosis and metallogenic pneumoconiosis, HR=2.67, 95% CI: 1.47-4.87; mixed pneumoconiosis and metallogenic pneumoconiosis, HR=2.25, 95%CI: 1.11-4.56) were the factors affecting the survival time of pneumoconiosis patients (P<0.05) . Conclusion: Pulmonary tuberculosis may increase the risk of death in patients with pneumoconiosis. Mineral dust pneumoconiosis, mixed pneumoconiosis and stage Ⅲ pneumoconiosis may also have higher risk of death.
