Clinical statistics analysis on the characteristics of pneumoconiosis of Chinese miner population

Background: Pneumoconiosis is one of the most common occupational diseases, which shows the progressive and irreversible pathological changes. It ultimately can induce pulmonary failure and lead to death. To date, these patients have no curative treatment option under the current standard of care, so it is especially important to delay the onset of the disease and slow down its progression. Therefore, understanding of clinical features of pneumoconiosis is particularly critical for medical intervention. Methods: We collected the clinical data from 118 pneumoconiosis cases of miners admitted in hospital and processed the statistics analysis by using the Chi-square test and the risk assessment. Results: Compared to other types of miners, gold miners are liable to cause Broncho-pulmonary co-infection with Chi-square value 18.748 and the P value 0.05. Moreover, smoking history exhibited a deteriorating effect to the overall survival (OS) with 9.546 of Chi-square value and P Conclusions: Our studies suggest that the history of smoking and exposure time of dust play important roles in the development of pneumoconiosis and smoking could be a factor that determines the treatment options depending on patients’ smoking history.
