| 目的 调查北京市医疗机构放射诊断设备、放射诊断人员和检查频次,为临床放射诊断工作中辐射防护措施制订及放射诊断资源的配置提供数据支持。方法 2023年10月,采用问卷调查的方法,向分布于各市辖区的不同等级医疗机构中的北京医学会放射技术分会委员发放调查表,收集北京市所辖14个市辖区,包含三级甲等、三级、二级共38家医疗机构的放射诊断设备、从业人员信息和不同X射线诊断成像设备在2018年至2022年的应用频次。使用MicroSoft PowerBI软件对数据进行整理并形成报表模型,使用RStudio软件对设备、人员和检查项目频次的数据进行统计学分析。结果 北京市38家医疗机构拥有591台各种类型的放射诊断设备,放射科工作人员2 018人,其中技师1 037人、医师738人,单台设备平均配备技师1.77人、医师1.26人。在2018至2022年间的所有放射诊断检查中,计算机体层成像(CT)检查频次占比最高,总发展速度为138.06%,平均发展速度为108.40%;其中胸部CT的总发展速度为225.20%,平均发展速度为122.50%;X射线摄影的检查频次占比仅次于CT,总发展速度为70.20%,平均发展速度为91.53%;其中胸部X射线摄影的总发展速度为63.89%,平均发展速度为89.41%。结论 2018年至2022年,38家医疗机构中X射线摄影检查频次波动较大、整体下降,CT检查频次上升,其中胸部CT检查频次和占比均呈增长趋势,应重视CT检查的正当性。 |

| Objective To investigate devices for radiodiagnosis used in medical institutions in Beijing, China, as well as radiation workers and the devices' application frequencies, in order to provide data support for determining radiation protection measures and allocating resources for clinical radiodiagnosis. Methods In October 2023, questionnaires were distributed to the members of the Radiation Technology Branch of the Beijing Medical Association who work in medical institutions at different levels across varying districts of Beijing. The collected data included information about devices for radiodiagnosis and radiation workers, as well as the application frequencies of various medical X-ray imaging devices during 2018-2022, in 38 medical institutions of Level 3 Grade A, Level 3, and Level 2 in 14 municipal districts of Beijing. Then, the collected data were organized using the Microsoft Power BI software to form report models, followed by the statistical analysis of data on the devices, radiation workers, and application frequencies were using the RStudio software. Results The 38 medical institutions in Beijing possess 591 devices for radiodiagnosis and 2 018 staff in the departments of radiology, including 1 037 radiologic technologists and 738 physicians, with 1.77 technologists and 1.26 physicians arranged for a single device on average. From 2018 to 2022, among all examinations of radiodiagnosis, computed tomography (CT) scans showed the highest frequencies, with total and average annual growth rates of 138.06% and 108.40%, respectively. Specifically, chest CT scans exhibited total and average annual growth rates of 225.20% and 122.50%, respectively. X-ray imaging ranked second in application frequency, with total average annual growth rates of 70.20% and 91.53%, respectively. Notably, chest X-ray imaging showed total and average annual growth rates of 63.89% and 89.41%, respectively. Conclusions From 2018 to 2022, X-ray imaging examinations displayed significantly fluctuating frequencies with an overall decline trend in the 38 medical institutions. In contrast, the CT scans showed increased frequencies, with chest CT scans displaying an increased frequency and proportion. This necessitates ensuring the justification of CT scans. |
