RESUMO
To revise GBZ 188 Technical Specification for Occupational Health Surveillance based on national laws, regulations, standards, specifications and legal documents of occupational disease, and combination with the actual situation in China. The main modifications are as follows: the occupational health surveillance for workers exposed to toluene (xylene may implement by reference), bromopropane, methyl iodide, ethylene oxide, chloroacetic acid, indium and its compounds, coal tar, coal tarasphalt, asphalt, β-naphthylamine, dust of metal and its compounds(tin, iron, antimony, barium and its compounds), hard metal dust, erionite dust, low temperature, laser, tick-borne encephalitis virus, Borrelia burgdorferi, and human immunodeficiency virus, for scraper or grind operators, and underground workers using squatting or kneeling position, crawling position, side-lying position, or shoulder position for a long period of time are included. The emergency health screening for workers exposed to arsenic, fluorine and its inorganic compounds, and acrylamide are included. The occupational medical examination (OME) for workers exposed to amino and nitro compounds of benzene, phosgene, monomethylamine, organic fluorine and dimethyl sulfate has been adjusted and made mandatory, with corresponding assessments required upon leaving the job. The special occupational health surveillance for workers exposed to mycobacterium tuberculosis and hepatitis virus is removed. The OME conclusion of reexamination is removed, and standardize recheck/additional inspection requirements. The optional items in OME performed before, during and after leaving post are removed, but the optional items in emergency medical examination are retained. Additional OME items are added. The Guideline for OME Summary Reports is added as informative appendix, and so on. The revised GBZ 188 Technical Specification for Occupational Health Surveillance is more scientific and practical.
RESUMO
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.
