摘要
目的了解大连市2017年医疗机构(除口腔诊所或门诊)开展放射诊疗服务情况、接受X射线诊断的患者或受检者情况和监测点医疗机构的辐射防护情况。方法通过对大连市所有医疗机构的调查和对15家监测点医疗机构的监测,对全市医疗机构开展放射诊疗服务、接受X射线诊断的患者或受检者以及监测点医疗机构的放射工作场所辐射防护检测、X射线装置质量控制检测情况进行分析评价。结果结果显示全市277家医疗机构均开展了X射线诊断学,开展率为100%;开展介入放射学的有14家,占5.1%;开展核医学的有5家,占1.8%;开展放射治疗的有8家,占2.9%。全市医疗机构使用X射线诊断的人次数为4140427,其中常规X射线诊断2285306人次,占55.2%;CT诊断1740424人次,占42.0%;其它诊断114697人次,占2.8%。15个监测点医疗机构、141个放射工作场所辐射防护水平均合格,X射线装置的性能检测均合格。结论CT机的使用率非常高,应注意CT机使用的正当性,并加强辐射防护的管理。
Objective To understand the medical institutions(except oral clinics or outpatient clinics)in dalian city in 2017 to carry out radiological diagnosis and treatment services,the patients or examinees receiving X-ray diagnosis and the radiation protection situation of the medical institutions at the monitoring points.Methods Through the survey of dalian all med-ical institutions and to 15 medical institutions of monitoring,to the city of radiological diagnosis and treatment of medical institutions and service,or subjects and in patients undergoing X-ray diagnostic monitoring radioactive workplace radiation protection of medical institutions detection,X-ray equipment quality control testing situation analysis evaluation.Results The re-sults showed that all 277 medical institutions in the city had carried out X-ray diagnosis,with the development rate of 100%.Fourteen medical institutions had carried out interventional radiology,accounting for 5.1%.Five medical institutions,or 1.8 percent,had carried out nuclear medicine;Eight medical institutions,or 2.9%,had carried out radiation therapy.The number of times using X-ray diagnosis in medical institutions in the city was 4140427,among which 2285306 person times received conventional X-ray diagnosis,accounting for 55.2%.CT diagnosis reached 1740424 persontimes,accounting for 42.0%.Other diagnoses were 114697,or 2.8%.The radiation protection level of 15 medical institutions and 141 radiation workplaces at the monitoring sites were all qualified,and the performance test of the X-ray device was all qualified.Conclusion The utilization rate of CT machines is very high,so we should pay attention to the legitimacy of the use of CT machines and strengthen the management of radiation protection.
