| 目的 分析山东省X射线影像诊断应用分布特点及影响因素，估算全省的X射线影像诊断的应用频度，为X射线装置的配置提供数据支撑。方法 采用随机分层典型抽样方法，抽取山东省10个地级市的32家医疗机构作为样本医院，调查医疗机构基本信息及受检者的年龄、性别、检查类型和检查部位等信息，分析X射线应用项目的分布情况并利用多元线性回归模型进行预估。结果 共有受检者14 694 085例，抽取的样本中男女比例并非完全均匀。共收集2016年的X射线影像诊断信息2 099 155条，常规X射线摄影应用频度最高，占59.49%；其次为CT检查，占28.34%；且两类检查的频度呈随年龄增加的趋势。在常规X射线诊断检查和CT检查的总频度中，三级医院所占比例最高，达52.13%；二级医院较低，占30.09%；一级医院最低，为17.77%。常规X射线摄影中的胸部摄影占比最高，占32.79%；CT检查中的颅脑检查占比最高，为10.07%。透视检查、乳腺摄影和牙科摄影主要集中在三级医院，一级医院主要以X射线摄影为主。多元线性回归模型显示，常规X射线诊断项目（包含常规X射线摄影、透视造影、牙科摄影和乳腺摄影）的应用频度与设备量、门急诊量、三级医院呈现正相关（t=4.334、3.615、2.339，P<0.05），CT检查与设备量和住院量呈现正相关（t=2.167、2.595，P<0.05）。通过估算，山东省常规X射线诊断和CT照射检查的检查频度分别491.17人次/千人口和258.17人次/千人口。结论 山东省X射线照射频度较"九五"期间显著增长，各相关部门应采取有力措施，加强医疗照射防护，降低辐射危害。 |

| Objective To analyze the distribution characteristics and influencing factors of X-ray diagnostic imaging in Shandong province, and to estimate the application frequency of X-ray diagnostic imaging in the province, and provide data support for X-ray equipment. Methods A random sampling method was used to extract 32 medical institutions as respondents from 10 prefecture-level cities in Shandong province. The basic information of medical institutions and the age, sex, examination and procedure of the subjects were analyzed. The distribution of the X-ray application was analyzed and estimated by using a multiple linear regression model. Results Totally 14 694 085 subjects were surveyed, and the proportion of male and female in the sample was not completely uniform. A total of 2 099 155 X-ray diagnostic information was collected in 2016, and the frequency of conventional radiography was the highest, accounting for 59.49%. The next was CT examination, accounting for 28.34%. The frequency of the two examinations showed an increasing trend with the age of subjects. For the total frequency of conventional diagnostic radiography and CT examination, the tertiary hospitals accounted for the highest proportion of the total, up to 52.13%, while the secondary hospitals accounted for the relatively low proportion of 30.09%, and the primary hospitals the lowest with 17.77%. The chest radiography had the highest proportion in conventional radiography accounting for 32.79% of the total frequency of X-ray diagnostic imaging, and the head procedure had the highest proportion in CT examination, accounting for 10.07% of the total frequency of X-ray diagnostic imaging. The fluoroscopy, mammography and dental radiography were mainly concentrated in the tertiary hospitals, and the primary hospitals had mainly radiography. Multiple linear regression models showed that the frequency of application of conventional X-ray diagnostic imaging(including radiography, fluoroscopy, dental radiography and mammography) was positively correlated with equipment quantity, number of outpatient and emergency patients, and tertiary hospitals (t=4.334, 3.615, 2.339,P<0.05). CT examination was positively correlated with equipment quantity and the number of inpatient (t=2.167, 2.595,P<0.05). The frequency of conventional X-ray diagnostic imaging and CT examination in Shandong province were estimated about 491.17 examinations per 1 000 population and 258.17 examinations per 1 000 population respectively. Conclusions The frequency of X-ray exposure in Shandong province increased significantly compared with that during the "9th Five-Year Plan" period. All relevant departments should take effective measures to strengthen medical radiation protection and reduce radiation risk. |
