Utilization and influencing factors of whole lung lavage for patients with pneumoconiosis in Chinese mainland from 2018 to 2021 / 中国职业医学

ABSTRACT

Objective: To evaluate the utilization and influencing factors of whole lung lavage (WLL) for patients with pneumoconiosis. Methods: A total of 10 524 pneumoconiosis patients who sought medical treatment from 2018 to 2021 were selected as the research subjects using a combination of stratified random sampling and non-random sampling methods. The patients were from 27 provincial administrative regions of Chinese mainland (excluding Shanghai City, Tianjin City, Hainan Province and Tibet Autonomous Region). The effects of demographic and sociological characteristics, disease-related factors, and economic and social security status on WLL utilization were analyzed. Results: The WLL rate of pneumoconiosis patients was 17.8% (1 871/10 524). The main reason for promoting WLL in pneumoconiosis patients was “doctor's advice”, accounting for 65.4%； followed by “known-pneumoconiosis-patients had WLL” and “patient's recommendation”, accounting for 24.1% and 18.1%, respectively. Multivariate logistic regression analysis showed that age, body mass index, smoking index, education level, survey area, source of patients, current employment status, nature of dust-exposed unit, stage of pneumoconiosis, type of pneumoconiosis, pneumoconiosis symptoms (coughing up phlegm, chest pain, dyspnea, joint pain), contraindications to WLL (tuberculosis, pulmonary heart disease), family annual income, medical insurance for urban employees, proportion of medical insurance reimbursement, disability benefits, and social assistance were the influencing factors of WLL utilization in pneumoconiosis patients (all P<0.05). Conclusion: A large proportion of pneumoconiosis patients used WLL. The influencing factors of WLL utilization included demographic and sociological characteristics, disease-related factors, economic and social security status, and more. It is necessary to protect the interests of pneumoconiosis patients, strengthen occupational health education and health promotion for pneumoconiosis patients, standardize the use of WLL in medical institutions, and make rational use of WLL.
