Preliminary study on the evaluation of pneumoconiosis

Objective Select the appropriate disease assessment indicators, formulate the comprehensive evaluation group of pneumoconiosis patients, and explore the role of the comprehensive evaluation grouping in the clinical evaluation of pneumoconiosis, and provide the basis for the prognosis of pneumoconiosis. Methods Combined with clinical symptoms, pulmonary function, pneumoconiosis stage, acute exacerbation and complications, a comprehensive assessment of pneumoconiosis patients was established.138 newly diagnosed pneumoconiosis patients were divided into low risk group, middle risk group and (very) high risk group. The patients were followed up by telephone to record their health status and quality of life within one year after discharge from hospital. Analysis of the relationship between the comprehensive assessment group of patients with pneumoconiosis and symptom score, pulmonary function, pneumoconiosis stage, acute exacerbation and complications. The relationship between the comprehensive assessment group of pneumoconiosis patients and the risk events (the number of visits, hospitalization, mechanical ventilation, death cases in one year) and CAT score were analyzed. Results There were significant differences in clinical symptoms, pulmonary function injury, pneumoconiosis stage, acute exacerbation and complications among patients in low risk group, middle risk group and (very) high risk group (P<0.01) . With the increase of comprehensive assessment score, CAT score increased, the risk events increased, the difference was statistically significant (P<0.01) . Spearman correlation analysis showed that the comprehensive assessment group was significantly correlated with the number of visits, hospitalization, mechanical ventilation, deaths and CAT score in one year. Conclusion Combined with clinical symptom assessment, pulmonary function assessment, chest imaging assessment, acute exacerbation assessment, and complication assessment, the pneumoconiosis patients' comprehensive assessment group formulated can evaluate the severity of pneumoconiosis patients, and make a more accurate and comprehensive judgement of the disease.
