摘　　要：目的 分析嘉兴市医疗卫生机构放射诊疗设备配置数量、放射工作人员结构、防护设备配备、防护用品配备及诊疗照射频度，为进一步优化资源配置提供研究数据。方法 按照全国放射卫生监测项目工作方案的要求，使用分层随机抽样的方法抽取嘉兴市三级、二级、一级及其他医院等各等级医院的50%放射诊疗机构共计111家。采用全国统一的调查表，对这些放射诊疗机构的基本情况、放射诊疗设备、防护配套设备和放射工作人员数以及放射诊疗频度等方面进行调查和分析。结果 抽取的111家医院中，三级、二级、一级及其他医院数构成比分别为13.5%、21.6%、46.9%和18.0%；在各等级医院中，三级医院的放射治疗设备、核医学设备、介入放射学设备和X射线影像诊断设备分别占100%、100%、57.9%和38.0%，占比较高；一级医院常规摄影、透视放射诊断类设备占比分别为34.2%和50.0%，明显高于其他等级医院；CT、乳腺机分布在二级及以上医院。放射诊断放射防护各类用品和介入放射学各类防护用品配备齐全；南湖区X射线诊断、CT诊断、介入治疗诊断、放射治疗、核医学诊断和核医学治疗等各类诊疗项目频度依次为178.9、157.5、3.1、1.5、2.2和0.1人次·千人-1·年-1，在嘉兴市各区域中占比较高。结论 三级医院的放射诊疗设备数量、放射工作人员数量高于二级及以下医院，各等级医院防护用品配备充足，南湖区放射诊疗频度明显高于其他区县市医院。Objective To analyze the diagnostic radiology equipment number, radiological staff structure, protection allocated at the medical institutes in Jiaxing city, with the purpose to provide basic data for the further optimization of resource allocation. Methods As required by the national radiation health monitoring program and using the stratified random sampling method, a total of 111 hospitals at grades Ⅲ,Ⅱ,Ⅰand other types were used to select 50% radiological institutions in Jiaxing. Unified questionnaires were used to investigate the basic situation in these hospitals, such as diagnostic radiology equipment, configurable protection equipment, radiation worker number and diagnostic frequency. Results The hospital number at grades Ⅲ,Ⅱ,Ⅰand other types accounted separately for 13.5%, 21.6%, 46.9% and 18.0% of the total. The equipment numbers for radiotherapy, nuclear medicine, interventional radiology and X-ray imaging at grade Ⅲ hospitals accounted for 100%, 100%, 57.9% and 38.0%, respectively, significantly higher than others. The numbers of conventional photofluorography and fluoroscopy equipment at grades Ⅰ hospitals accounted for 34.2% and 50%, slightly higher than others; CT and mammography devices were distributed at the grades Ⅱ and Ⅲ hospitals. The frequencies at X-ray diagnosis, CT diagnosis and interventional therapy and diagnosis, radiotherapy, and nuclear medicine diagnosis and therapy were 178.9, 157.5, 3.1, 1.5, 2.2 and 0.1 per thousand person-year in Nanhu district, which were higher than in the other areas of Jiaxing city. Conclusions Grade Ⅲ hospitals have more diagnostic radiology devices and radiation workers than in non-grade-Ⅲ hospitals. These hospitals were all equipped with adequate amount of protection equipment. The frequency of diagnostic radiology in Nanhu district hospital was significantly higher than that in other district hospitals.
