某市不同级别医院介入的放射卫生现状调查

目的 调查珠三角某市不同级别医疗机构介入放射学的放射卫生现状。方法 通过采用全面普查的方法，选择该市截至2019年12月31日已开展介入治疗业务的所有医疗机构作为研究对象。采用现场流行病学调查的方法调查研究对象的基本情况、防护设施现状、环境辐射剂量、个体防护用品现状、职业健康监护现状。结果 截至2019年12月31日，该市7家医疗机构共有12台介入治疗设备，现有180名介入治疗从业人员。不同级别医院的介入治疗从业人员构成差异无统计学意义（P > 0.05）。不同级别医院的介入治疗的防护设施构成差异无统计学意义（P > 0.05）。三甲医院介入治疗设备机房的周围辐射剂量高于二甲医院，差异有统计学意义（P < 0.05）。不同级别医院的介入治疗个体防护用品构成差异无统计学意义（P > 0.05）。二甲医院上岗前职业健康检查和在岗期间的职业健康检查比例高于三甲医院（P < 0.01）。结论 该市不同级别医疗机构介入治疗业务发展良好，加强对介入治疗申请辐射防护管理、积极开展建设项目的职业病危害放射防护评价，督促从业人员按要求进行职业健康监护检查，可能有助于提高该市介入治疗的放射卫生防护水平。

Current situation of radiological health of interventional radiology of different ranks medical institutions in a city

Object the current radiological health situation of different ranks medical institutions of interventional radiology in a city of Pearl Delta.Methods all the medical institutions in the city, which had carried out interventional radiology before December 31, 2019 as the research objects by survey. By using the method of field epidemiological investigation, the basic situation of general messages, the status of protective facilities, environmental radiation does, personal protective equipment, occupational health monitoring were investigated.Results There were 12 interventional radiology equipment and 180 employees in 7 medical institutions in the city, before December 31, 2019. There was no statistical significance in the composition of employees of different ranks medical institutions (P > 0.05). There was no statistical significance in the composition of protective facilities for interventional treatment in different ranks hospitals (P > 0.05). The environmental radiation dose in interventional radiology devices room of grade A class 3 hospital was higher than that of grade A class 2 hospital (P < 0.05). There was no statistical significance in the composition of individual protective equipment for interventional therapy in different ranks medical institutions (P > 0.05). The proportion of occupational health examination before work and during work in grade A class 2 hospital was higher than A class 3 hospital (P < 0.01).Conclusion The current situation of radiological health of different ranks medical institutions of interventional radiology in a city of Pearl Delta was good momentum. It may be helpful to improve the radiological health protection level of interventional therapy in this city by strengthening the radiological protection management of applying for interventional therapy, actively carrying out the evaluation of radiological protection against occupational disease hazards in construction projects, and urging the employee to carry out the occupational health monitoring inspection as required.
