摘　　要：目的通过对26家医疗机构的抽样调查,对南京市放射诊断的总体情况进行初步分析,估算全市普通放射诊断和CT扫描的应用频度。方法根据哨点监测工作方案,将本市医疗机构按医院级别分为三层,再随机抽取26家医疗机构。通过调查表,对机构基本情况、放射诊断设备基本情况及放射诊断检查频次等内容进行调查。结果26家医疗机构放射诊断检查频次为1043307人次,占门急诊总量的15.76%。一级、二级、三级医院放射诊断检查频次占门急诊量的比例不同,差异有统计学意义(P<0.05),其中以二级医院的比例最高(32.17%)。常规X射线诊断在所有级别医院的放射诊断检查中的构成比最高,占放射诊断检查的70.81%。CT扫描检查全部分布在二级和三级医院,占放射诊断总数的25.82%,摄影检查占常规X射线诊断检查的比例最高,在三级医院和二级医院中均超过97%。在一级医院中透视检查的构成比为27.72%,高于三级和二级医院。利用此次调查结果和卫生统计年鉴数据,采用多元逐步回归方法,估算南京市2017年普通放射诊断应用频度为954人次/千人口,CT扫描应用频度为246人次/千人口。结论面对南京市放射诊断的发展现况,需更加重视医疗资源的合理配置,加强医疗照射的防护,加大放射卫生监督管理的力度,确保放射诊疗活动的正当性。Objective To preliminarily analyze the general situation of radiological diagnosis in Nanjing and to estimate application frequency of common radiological diagnosis and CT scan in Nanjing by sampling survey of 26 medical institutions.Methods Medical institutions in Nanjing were divided into three layers and then 26 medical institutions were randomly selected and their information including institutional grade,diagnostic equipment,number of radiological diagnosis examination in 2017 and so on was collected by issuing the unified questionnaires.Results There were 1043307 common radiographic diagnostic examinations in the 26 medical institutions,accounting for 15.76%of the total number of outpatient and emergency visits.The proportions inprimary hospital,secondary hospital and tertiary hospital were difference(P<0.05),and the proportion of secondary hospital was the highest(32.17%).The proportions of general X-ray diagnosisin the number of common radiographic diagnostic examinations were the highest in all grade hospitals.CT scans were all distributed in secondary hospital and tertiary hospital,accounting for 25.82%of the total number of radiographic diagnoses.The proportions of radiographic examinations in the number of general X-ray diagnostic examinations exceeded 97%in secondary hospital and tertiary hospital.The proportions(27.72%)of fluoroscopy in the number of general X-ray diagnosis in primary hospitals was higher than that in tertiary and secondary hospitals.The frequency of common radiological diagnosis was estimated at 954 per 1000 persons,and 246 per 1000 persons for CT scans.Conclusion It is necessary to pay more attention to the allocation of medical resources,and strengthen the supervision and management of radiological health,and ensure the legitimacy of radiological diagnosis in order to adapt to the development of radiological diagnosis in Nanjing.
