| 目的 掌握武汉市放射诊疗机构X射线诊断设备基本情况及频度水平,为卫生行政部门制定医疗照射防护策略及合理调配放射诊疗资源提供依据。方法 采用普查的方法,通过"武汉市职业病防治综合管理信息平台"收集2022年全市1 030家放射诊疗机构(不包括部队和武警医院)填报的X射线诊断设备基本情况和诊断人次调查表,将调查的各类型X射线诊断人次数除以2021年底武汉市常住人口数,获得武汉市不同X射线诊断应用频度。结果 武汉市1 030家放射诊疗机构拥有各类型X射线诊断设备2 540台,放射工作人员7 062人,其中37.76%的设备和75.01%的放射工作人员集中在三级医院;全市平均每百万人拥有186.10台X射线诊断设备,其中数字X射线摄影机(DR)48.65台/百万人最多,其次为口内牙科机31.21台/百万人;全市X射线诊断总数11 884 582人次,集中在X射线摄影与计算机体层成像(CT)诊断检查,分别占43.61%与43.59%,频度分别为379.75人次/千人口与379.52人次/千人口;中心城区放射诊疗资源配置优于远城区。结论 武汉市X射线诊断设备发展较快且仍有增长空间,诊断频度未恢复到新冠疫情前水平,中心城区与远城区放射诊疗资源配置需统筹优化,医疗照射防护管理力度应不断加强,以促进区域间放射诊疗事业可持续发展,保障患者及受检者健康安全。 |

| Objective To attain comprehensive insight into the diagnostic X-ray equipment and examination frequency in radiological diagnosis and treatment institutions in Wuhan, with the purpose of assisting the health administration department in formulating medical exposure protection strategies and efficiently allocating radiological diagnosis and treatment resources. Methods Using the census method, questionnaires on the basic information on diagnostic X-ray equipment and the annual number of examinations filled out in 2022 by the 1 030 radiological diagnosis and treatment institutions (excluding military and armed police hospitals) were collected through the Wuhan Prevention and Treatment Information Management Platform for Occupational Diseases. To obtain the data on number and frequency of diagnostic X-ray examinations, the different types of diagnostic X-ray examinations were divided by the total number of permanent residents by the end of 2021 in Wuhan. Results In Wuhan, 1 030 radiological diagnosis and treatment institutions had 7 062 radiation workers and 2 540 diagnostic X-ray units of various types. 37.76% of units and 75.01% of radiation workers were concentrated in tertiary hospitals. The number of diagnostic X-ray units per million population was 186.10, with the top two being 48.65 DR machines per million population and 31.21 intraoral dental machines per million population. The total number of diagnostic X-ray examinations was 11 884 582, with plain radiographs and computed tomography (CT) examinations accounting for 43.61% and 43.59% of the total, respectively. The annual frequency of examinations was 379.75 and 379.52 per 1 000 population, respectively. Radiodiagnosis and treatment resources were higher in central urban areas than that in remote urban areas. Conclusions The development of diagnostic X-ray equipment in Wuhan was experiencing rapid growth, with potential for further expansion,and the frequency has not yet recovered to the level before the COVID-19 pandemic. The allocation of radiodiagnosis and treatment resources between central urban areas and remote urban areas needs to be coordinated and the management of medical radiation protection should be continuously strengthened, so as to promote the sustainable development of inter-regional radiodiagnosis and treatment, and ensure the health and safety of examinaed patients and indivuduals. |
