江西省医用X射线诊断应用频度调查

目的 对江西省医疗机构医用X射线诊断设备进行应用频度抽样调查,掌握江西省医用X射线诊断应用频度水平和受检者的分布特点,估算全省普通X射线诊断、计算机X射线断层摄影装置（CT）、介入放射学的应用频度水平。方法 采用分层典型抽样方法,在全省范围内抽取三级、二级、一级和其他各级样本医院,以发放调查问卷的形式对样本医院进行应用频度的调查与分析。结果 医用X射线诊断受检者男性多于女性;年龄分布中"0~"组比例最低,"40~"组占比例最高;估算出江西省2016年度X射线诊断频度约为543.07次/千人口,CT诊断频度约为244.79次/千人口,介入放射学频度约为6.28次/千人口。结论 江西省医用X射线诊断应用频度迅猛发展,给放射卫生工作提出了巨大的挑战,因此应加强医用X射线诊断医疗照射的监督管理并合理配置使用各类医疗资源。

Survey on frequency of medical X-ray diagnosis in Jiangxi province

Objective To study the frequency of diagnostic medical radiological examinations and the distribution of examinees in Jiangxi province by sampling investigation, including normal X-ray diagnosis, computed tomography (CT), interventional radiology. Methods Hospitals of different levels in Jiangxi province were chosen by the typical sampling method. Questionnaire was used in this study. Results There were more male examinees than female in diagnostic medical radiological examinations. For the distribution of age, the "0-" group accounted for the lowest and the "40-" group the highest proportion. The annual frequency in 2016 in Jiangxi was 543.07 examinations per 1 000 population for normal X-ray diagnosis, 244.79 examinations per 1 000 population for CT scanning, 6.28 examinations per 1 000 population for interventional radiology. Conclusions The frequency of diagnostic medical radiological examinations in Jiangxi has been increased rapidly which made a huge challenge for radiological protection. Therefore, the supervision and management of diagnostic medical radiological examinations should be enhanced and medical resources should be rationally allocated.
