| Objective To explore the non-coverage rate (NCR) of occupational health examination for radiation workers. Methods The occupational health examination data of 1 019 radiation workers were selected in 2019 in Pingdingshan City, Henan Province. Statistical analyses were performed, on the one hand, based on the NCR of different examinations, including collection of personal basic information, blood pressure, internal medicine routine, dermatology, ophthalmology (color sensation, visual acuity, lens slit, vitreum, ocular fundus), DR chest X-ray, color B-ultrasound of abdomen and thyroid, ECG, blood (blood routine, biochemical test, thyroid function, micronucleus test or chromosomal aberrations analysis of peripheral blood lymphocytes) and urine routine. On the other hand, the analyses were also based on the NCR of various examinations for different occupational radiation categories, genders, age groups and medical institutions at different levels. Results There were statistically significant differences in the NCR for 1 019 radiation workers (χ2=2 580.657, P<0.05), with the highest value of 46.0% in DR chest X-ray examination, followed by urinary routine of 9.3%, and the lowest value of 0 in blood examination. The trend in NCR for radiation workers of different categories was higher in medical application than in industrial application (χ2=93.969, P<0.05), and higher in women than in men (χ2=24.228, P<0.05). Among different age groups, the NCR under the age of 30 was the highest, followed by above the age of 50, and the lowest over 40 years old (χ2=12.623, P<0.05). As a whole, the higher the level of medical institutions was, the higher the overall NCR was (χ2=24.725, P<0.05). Among different occupational groups of medical applications, the trend in NCR of each examination was:radiodiagnosis > interventional radiology > radiodiagnosis (χ2=23.263, P<0.05). The NCR of the various examinations were higher in medical applications than in industrial applications including DR chest X-ray, color B-ultrasound of abdomen and thyroid, ECG, urine routine (χ2=141.776, 13.801, 11.228, 5.465, 4.825, P<0.05) and higher in female than male including DR chest X-rays and urine routine(χ2=43.032,23.247, P<0.05). Among different age groups, statistically significant differences in NCR were found (χ2=14.285, 9.519, 7.958, 16.656, P<0.05) in color sensation and visual acuity, DR chest X-ray, color B-ultrasound of thyroid, urine routine. Between medical institutions at different levels, the NCR in color sensation and visual acuity, DR chest X-ray, ECG undetected rate were statistically significant (χ2=12.328, 29.831, 15.342, P<0.05). There were statistical significance in NCR of DR chest X-ray and urine routine between different occupational groups of medical applications (χ2=46.519, 14.109, P<0.05). Conclusions Continued effort should be made to strengthen the health management of radiation workers and carry out occupational health examinations in strict accordance with the relevant national requirements. |
