A survey of the frequency of medical exposure in Fangshan District of Beijing, 2019

Abstract

Objective To investigate the basic situation of radiodiagnosis and radiotherapy institutions and the frequency of medical exposure in Fangshan District, Beijing, China.

Methods A general survey using the questionnaire was conducted online to obtain the basic situation of the radiodiagnosis and radiotherapy institutions, the number of people in each type of radiodiagnosis and radiotherapy project, and the number of the usually resident population in the whole district in 2019, thus obtaining the frequency of medical exposure in each type of radiodiagnosis and radiotherapy project.

Results There were 60 radiodiagnosis and radiotherapy institutions, 565 radiology staff, and 199 sets of radiodiagnosis and radiotherapy equipment in the whole district in 2019. The frequency of medical exposure was 521.29 per 1 000 people, among which conventional medical diagnostic X-ray workers accounted for 301.79 per 1 000 people (57.89%) and computed tomography workers accounted for 207.56 per 1 000 people (39.82%). The number of tertiary hospitals accounted for 6.67% of the radiodiagnosis and radiotherapy institutions, and the number of people exposed tomedical radiation in tertiary hospitals accounted for 52.25% of the total. The number of secondary hospitals accounted for 5.00% of the radiodiagnosis and radiotherapy institutions, and the number of people exposed to medical radiation in secondary hospitals accounted for 27.83% of the total.

Conclusion The distribution of medical exposure in Fangshan District is uneven. The radiodiagnosis and radiotherapy technology used is relatively single. Relevant departments should strengthen macroscopic readjustment and control, and formulate reasonable policies, so as to rationally allocate and effectively utilize medical and health resources.
