| 目的 了解广东省医用X射线诊断医疗照射频度水平，为放射诊断的合理应用提供参考依据。方法 采用分层典型抽样的方法，选取广东省广州市、惠州市、江门市、茂名市、梅州市、潮州市和肇庆市等7个地区的56家医疗机构进行X射线诊断医疗照射频度情况调查，用调查样本的相关变量（医院总人次数、门急诊量、住院人数、放射工作人员数、放射诊断设备数）做多重线性回归分析，将有相关性的自变量拟合线性回归方程，以此来估算广东省2016年普通X射线诊断检查、CT诊断检查频度和医用X射线诊断检查的总频度。结果 胸部摄影在普通X射线诊断检查中样本例数最多，占比为60.84%；颅脑检查在CT诊断检查中的样本例数最多，占比为28.03%；心血管介入在介入放射学检查中的样本例数最多，占比为48.83%；普通X射线诊断检查、CT诊断检查和介入放射学检查均以"40~"年龄组例数所占比例最高，占比分别为47.95%、65.41%和75.64%；各类型的医用X射线诊断检查均集中在三级医院和二级医院。以此调查结果估算广东省2016年普通X射线诊断检查频度为699次/千人口，CT诊断检查频度为293次/千人口。广东省2016年医用X射线诊断检查的总频度为992次/千人口。结论 此次频度估算的结果有一定的局限性，但以较少的投入完成了此次调查。调查结果显示，广东省医用X射线诊断的频度水平发展较快，三级医院和二级医院的医用X射线诊断检查类型较多，有关部门应有针对性地加强受检者所受医疗照射的放射防护，积极引导正确合理应用放射诊断，努力实现趋利避害。 |

| Objective To obtain the information on the frequency of diagnostic X-ray examinations in Guangdong province in order to provide reference data for the rational application of diagnostic radiology. Methods A typical stratified sampling method was used to select 56 medical institutions in 7 districts in Guangdong province for the survey of the frequencies of diagnostic X-ray examinations. Multiple linear regression analysis was performed using the relevant variables of the surveyed sample (total number of hospitals, number of outpatients, number of inpatients, number of radiation workers, and number of diagnostic equipment). The dependent independent variables were fitted to the linear regression equation to estimate the frequency of routine diagnostic X-ray examinations and diagnostic CT examinations and the total frequency of diagnostic medical X-ray examinations in Guangdong province in 2016. Results By the largest percentage contribution, chest radiography accounted for 60.84% of the routine diagnostic X-ray examinations, brain scans 28.03% of diagnostic CT examinations, and cardiovascular interventions 48.83% of interventional radiology. For the group of above 40 years old, the largest percentage contributions were, respectively, routine diagnostic X-ray examination 47.95%, diagnostic CT examinations 65.41%, and interventional radiology 75.64%. All types of medical X-ray examinations are concentrated in the tertiary and secondary hospitals. Based on this survey, the examination frequencies for 2016 in Guangdong were estimated to be, respectively, diagnostic X-ray examination 699 examinations per 1 000 population and CT diagnostic 231 examinations per 1 000 population, with the total of 992 examinations per 1 000 population. Conclusions This survey was completed to a limited degree and less investment. The results showed that the diagnostic radiology in Guangdong province is developing with increased frequencies, with wide varieties of X-ray examination types in the tertiary and secondary hospitals. Relevant competent departments should pay attention to strengthening the radiation protection of examined individuals and actively providing guidance on the correct and rational application of diagnostic radiology so as to achieve profit and avoid disadvantages. |
