Abstract:
Objective:To ascertain the distribution of interventional radiodiagnosis and treatment resources and the current situation of radiological protection in Beijing, standardize the interventional radiodiagnosis and treatment, and promote the implementation of radiation protection regulatory measures.Methods:Various medical institutions at differetn levels that perform interventional radiodiagnosis and treatment in Beijing were identified as the survey objects. With special questionnaires designed, the investigation groups at two levels of municipality and district was established to investigate the basic situation of interventional radiology and occupational health monitoring by the end of 2020. The indexes and parameters were analyzed and evaluated under the relevant national regulations and standards.Results:By the end of 2020, there were 93 medical institutions performing interventional radiology in Beijing, together with 236 digital subtraction angiography machines (DSA) with higher than 800 mA. A total of 135 593 cases of interventional radiological surgical operation were performed. There were 40 hospitals annually performing more than 1 000 cases and 41 hospitals perfoming 10-1 000 cases. There were 3 539 interventional radiological workers, with 99.0% holding radiological worker certificates. The passing rates of occupational health examination, personal dose monitoring and radiation protection training were 96.9%, 99.5% and 95.8%, respectively. A total of 3 532 sets of protective articles were provided for the workers, of which 98.9% were equipped with split or integrated lead clothing, but 6.5% were not equipped with lead protective glasses and 54.9% were not equipped with lead protective gloves.Conclusions:The radiation protection management for the interventional radiodiagnosis and treatment is generally good. However, the regulatory mechanism should be further improved based on the current distribution of interventional radiodiagnosis and treatment resources, with focus on strengthening the occupational health examination, the radiation protection training, and the configuration and use of protective equipment.
