摘　　要：目的 调查四川省医疗机构辐射防护现状,为实施省内放射诊疗防护科学管理和资源优化提供参考依据。方法采用问卷调查法对四川省21个市(州)开展放射诊疗活动(不含牙科诊所)的医疗机构进行调查分析。结果 截至2023年底,四川省内开展放射诊疗的医疗机构3 424家,其中三级医疗机构280家(8.18%),二级医疗机构647家(18.90%),一级医疗机构1 104家(32.24%),未评级医疗机构1 393家(40.68%)。从事放射工作人员共31 763人。全省共有放射诊疗设备9 056台,三级医疗机构3 346台(36.95%),二级医疗机构2 057台(22.71%),一级医疗机构1 510台(16.67%),未评级医疗机构2 143台(23.67%),哨点医院设备初检合格率达96.00%,复检合格率达97.41%,其中使用10年以上占24.70%,5~10年占62.10%,5年以下占13.20%。年放射诊疗总量4 988.97万人次。省内放射个人防护用品48 877件,核医学与介入放射学的防护个人用品配置平均每台设备大于13件。与2014年相比,四川省开展放射诊疗机构的数量增长率27%,放射工作人员增长率251%,开展放射诊疗频次增长率215%。结论 放射设备更新较慢,使用时长大部分集中在5~10年,医疗机构应提高维护监测意识;各级医疗机构在放射诊断防护用品数量上均满足要求,在介入放射和核医学项目中配置的放射防护用品充足;放射诊疗频次增多,建议有关部门进一步加强放射设备防护监测,提升医疗机构放射诊疗水平,安全开展放射诊疗活动。Objective To investigate the current status of radiation protection in medical institutions in Sichuan Province,providing a reference for the scientific management and resource optimization of radiation diagnosis and treatment protection within the province.Methods A questionnaire survey was conducted to analyze medical institutions engaged in radiation diagnosis and treatment activities(excluding dental clinics) across 21 cities(prefectures) in Sichuan Province.Results By the end of 2023,there were 3 424 medical institutions in Sichuan Province conducting radiation diagnosis and treatment,includ-ing 280 tertiary institutions(8.18%),647 secondary institutions(18.90%),1 104 primary institutions(32.24%),and 1 393 unclassified institutions(40.68%).A total of 31 763 radiation workers were employed.The province had 9 056 radiation diagnosis and treatment devices,with 3 346 in tertiary institutions(36.95%),2 057 in secondary institutions(22.71%),1 510 in primary institutions(16.67%),and 2 143 in unclassified institutions(23.67%).The pass rate for initial inspections of sentinel hospital equipment was 96.00%,while the re-inspection pass rate was 97.41%.Devices over 10 years old accounted for24.70%,those between 5 to 10 years for 62.10%,and those under 5 years for 13.20%.The annual total of radiation diagnosis and treatment visits reached 49.8 897 million.The province had 48 877 pieces of personal protective equipment for radiation,with an average of more than 13 protective items per device in nuclear medicine and interventional radiology.Compared to2014,the number of institutions conducting radiation diagnosis and treatment increased by 27%,the number of radiation workers grew by 251%,and the frequency of radiation diagnosis and treatment activities rose by 215%.Conclusion The update of radiation equipment is slow,with most devices in use for 5 to 10 years,indicating a need for improved maintenance and monitoring awareness among medical institutions.All levels of medical institutions meet the requirements for the quanti
