| 目的 通过对内蒙古自治区样本医院的基本信息和放射诊断频度的调查，了解内蒙古自治区居民的医疗照射应用频度和受检者的年龄部位分布信息，为医疗照射的最优化提供依据。方法 采用分层抽样的方法在内蒙古自治区内选取12家样本医院，调查医院2015年度和2016年度的X射线诊断受检者性别、年龄和受检部位等基本信息，并根据门急诊量、住院人数、工作人员数等信息，利用多重线性回归模型，估算全区2015年度和2016年度的医用X射线诊断应用频度。结果 调查发现，三级医院的医疗照射实践总体上高于二级医院，二级医院高于一级医院，综合医院的医疗照射实践高于专科医院。估算出内蒙古自治区2015年度和2016年度常规X射线照射应用频度为223和233人次/千人口，CT照射频度为96和125人次/千人口，透视照射应用频度为1和2人次/千人口，牙科照射应用频度为35和19人次/千人口，乳腺照射应用频度为1和2人次/千人口。结论 内蒙古自治区放射诊断的频度水平持续发展，但不同级别和不同类型的医疗机构医疗照射实践差异较大，今后继续开展频度调查工作时应当兼具全面性与针对性。 |

| Objective To obtain the information on frequency of diagnostic medical X-ray examination and age distribution of examined individuals surveyed through samples from 12 hospitals in Inner Mongolia region to provide the basis for the optimization of medical exposure. Methods Stratified sampling method was used to select 12 hospitals in the region to survey the information of examined patients on sex, age and exposed location of patients undergoing medical X-ray examination in 2015 and 2016. Based on the information on number of inpatients, number of inpatients and total number of staff, the total frequency of medical X-ray examinations in the region for 2015 and 2016 was estimated by using multiple linear regression model. Results The survey showed that the total frequency of medical exposure was, in decreasing order, tertiary hospitals > secondary hospitals > primary hospitals, and meanwhile the general hospitals > specialized hospitals. Values on frequency in general hospitals in 2015 and 2016 were 223 examinations per 1 000 population and 233 per 1 000 in conventional X-ray examination, 96 per 1 000 and 125 per 1 000 in CT examination, 1 per 1 000 and 2 per 1 000 in fluoroscopy, 35 per 1 000 and 19 per 1 000 in dental radiology, 1 per 1 000 and 2 per 1 000 in breast fluoroscopy in the region, respectively. Conclusions The frequency of radiological diagnosis and treatment in Inner Mongolia showed an rapid upward trend, but varied greatly dependent on the levels and types of medical institutions. Further surveys should be expanded with focuses on their comprehensiveness and relevancy. |
