南京市放射诊断机构X射线设备及诊断频度调查

Investigation of X-ray equipment and radiodiagnostic frequency in Nanjing

目的掌握南京市放射诊断机构、设备基本情况和X射线诊断频度现状,为卫生健康行政部门合理调配医疗卫生资源提供依据。方法采用普查的方法,卫生行政部门以文件形式下发工作方案,放射诊疗机构在"江苏省放射卫生信息管理平台"填报相关调查表,再将汇总后的X射线诊断人次数除以2019年底南京市常住人口数,获得南京市X射线诊断频度。结果南京市拥有各级放射诊断机构347家,其中三级医院27家,二级医院52家,一级医院159家,未定级医院109家,放射工作人员3270人,各类型X射线诊断设备1285台,其中69.23%设备和44.57%的放射工作人员集中在三级医院;全市各类X射线诊断设备中,X射线摄影(DR)机数量最多(37.59%),其次为牙科机(20.70%);全市X射线诊断总数8563487人次,其中常规X射线诊断占55.28%,计算机体层成像(CT)诊断占35.98%;南京市X射线诊断频度1007.47人次/千人口,其中常规X射线诊断频度556.90人次/千人口,CT诊断频度362.46人次/千人口,其他诊断频度80.03人次/千人口,介入治疗频度8.08人次/千人口;X射线诊断检查主要集中在三级医院(62.23%),城区高于郊区。结论初步掌握了南京市放射诊断机构基本情况和X射线诊断频度现状,一级及未定级医院在放射工作人员配置上存在明显的不足,城区医疗资源优于郊区,卫生行政部门需加强宏观调控,以保障患者及受检者健康安全,减少公众集体剂量负担。

Objective To grasp the basic information on medical institutions,radiodiagnostic equipments and X-ray diagnosis frequency in Nanjing,in order to provide the health administration department with the basis to rationally allocate medical and health resources.Methods Using the census method,the work plan was issued in the form of a document by the health administration department,and the radiodiagnostic institutions filled in the relevant questionnaires on the Jiangsu Province Radiological Health Information Management Platform.The frequencies of X-ray diagnosis were obtained by dividing the number of people invloved in X-ray diagnoses by the total number of permanent residents at the end of 2019 in Nanjing.Results There were 347 radiodiagnostic institutions in Nanjing,including 27 tertiary hospitals,52 secondary hospitals,159 primary hospitals and 109 unrated hospitals.There were 3270 radiation workers and 1285 X-ray diagnostic equipment of various types in Nanjing,and 69.23%equipment and 44.57%radiation workers are concentrated in tertiary hospitals.Among all types of X-ray diagnostic equipment in the city,DR machines have the largest number(37.59%),followed by dental machines(20.70%).The total number of X-ray diagnosic examinations in the city was 8563487,with routine X-ray diagnosis accounting for 55.28%,CT diagnosis for 35.98%.Frequencies was estimated to be 1007.47 examinations per 1000 population in medical X-ray diagnosis,of which frequency of routine X-ray diagnosis was 556.90 per 1000 population,the frequency of CT diagnosis was 362.46 per 1000 population,the frequency of other diagnoses was 80.03 per 1000 population,and the frequency of interventional treatment was 8.08 per 1000 population.X-ray diagnostic examination was mainly concentrated in tertiary hospitals(62.23%),higher in the urban area than that in the suburban area.Conclusions The basic information on radiation diagnostic institutions and the current status of X-ray diagnostic frequency in Nanjing are initially ascertained.There are obvious deficiencies in the staffing of radiation in the primary and ungraded hospitals,and urban areas were superior to suburbs in medical resources.It is desirable to enhance the macroeconomic regulation of radiodiagnosis and treatment resources in order to protect the health and safety of patients and examinees and reduce the dose to the public.
