Abstract:

Objective To understand the quality control assessment of chest X-ray films of occupational health examination institutions in Guangzhou City from 2022 to 2024 and analyze its related influencing factors. Methods Totally 96 occupational medical examination(OME) organizations in Guangzhou were selected as study subjects for on-site quality assessment and quality control assessment of chest X-ray films of dust-exposed personnel from 2022 to 2024. Results A total of 96 OME institutions were sampled from 2022 to 2024,including 52 public hospitals and 44 private hospitals,and a total of 682 corrective actions were detected. Among them,the OME institutions that did not meet the requirements of organizational structure,quality control of OME work,quality management system,and reporting requirements of health examination information were 14,57,19 and 6,respectively. The correct rate of chest X-ray examination of total dust-exposed persons was 90.4%(3 940/4 358). OME institutions with non-compliant organizational structure and unqualified pneumoconiosis reading staff had higher rates of non-compliance in dust catching quality control than their corresponding compliant groups,respectively(χ2=4.731,4.731,both P<0.05). Public hospitals had lower rates of non-compliance in organizational structure and quality control of OME work than private hospitals(χ2=14.598, 13.701, both P<0.05). The non-compliance rate of reporting health examination information in OME institutions with late or omission of suspected occupational disease reporting was higher than that of the normal reporting of suspected occupational diseases group(χ2=13.937,P<0.05). The risk of substandard quality of dust catching results was higher in OME institutions with non-compliant organizational structure and unqualified pneumoconiosis reader assessment than in those with compliant organizational structure and qualified pneumoconiosis reader assessment(both P<0.05). Conclusion The quality control of chest X-ray radiographs in OME institutions in Guangzhou needs to be improved. Improving organizational structure and enhancing the ability of pneumoconiosis reading staff can help improve the quality of chest X-rays of dust exposed personnel.
