| 目的 调查山东省临沂市放射诊断设备、防护设备和用品、工作人员的配置状况以及放射诊断频度,为合理配置资源、加强放射诊断卫生管理提供数据支持。方法 2023年对临沂市所有具备放射诊断设备的医疗卫生机构(不含单纯的牙科诊所,以下简称"放射诊断机构")共353家进行放射诊断资源问卷调查。调查内容包括放射诊断设备(包括7类16种设备)、防护设备、防护用品的配置情况、工作人员数量以及X射线诊断频度。不同级别、不同地区机构设备和人员的比较采用秩和检验。结果 2023年,临沂市353家放射诊断机构均配置放射诊断设备,共配置放射诊断设备1 180台,每家诊断机构拥有放射诊断设备M(P25,P75)为2(2,3)台。单项设备中占比最高的是数字X射线摄影机(DR)和计算机X射线体层成像(CT)设备,分别为35.4%和32.5%,其次是影像增强器透视机(7.9%)和平板探测器透视机(7.6%),计算机X射线摄影机(CR)、3种乳腺X射线机、4种牙科X射线摄影机和骨密度仪占比均低于4.0%。共配置防护设备(辐射巡测仪)223台,机构配置率仅为47.0%。每家放射诊断机构均配置防护用品;共配置防护用品5 709件,以铅橡胶颈套、铅橡胶帽子、铅橡胶围裙为主(占比均超过20%)。2023年,临沂市从事放射诊断工作人员共有2 677人,男性为主(62.9%);平均拥有工作人员M(P25,P75)为3(2,5)人,其中男性2(1,4)人,女性1(0,2)人。放射诊断设备、防护用品、工作人员数量均存在等级差异,三级机构显著高于其他级别(χ2=109.04、83.05、96.90,P<0.05)。2023年临沂市拥有放射诊断设备为107.8台/百万人口(DR和CT分别为38.2和35.0台/百万人口)、工作人员为244人/百万人口(男性和女性分别为154和90人/百万人口);开展放射诊断频度543.7人次/千人口,其中CT诊断频度最多(342.7人次/千人口),其次为X射线摄影频度(157.8人次/千人口)。结论 2023年临沂市放射诊断机构均配置诊断设备和防护用品,百万人均拥有CT、DR、乳腺DR数量优于全国和山东省平均水平,放射诊断资源总体较好。但放射诊断资源配置存在一定不均衡性,目前主要侧重于三级机构;同时骨密度仪和乳腺X射线机相对不足,今后有待进一步调整和优化。 |

| Objective To survey the status of radiological diagnostic equipment, protective equipment and articles, personnel allocation, and exposure frequencies in Linyi city, Shandong province, and to provide data support for rational allocation of radiological resources and radiological health management. Methods In 2023, a questionnaire survey was conducted of radiological diagnostic resources in 353 medical health institutions with radiological diagnostic equipment (excluding simple dental clinics, hereinafter referred to as radiological diagnostic institutions) in Linyi. The survey included the radiological diagnostic equipment (including 16 types of equipment in 7 categories), protective equipment and articles, the number of staff, and the exposure frequencies of X-ray diagnosis. The comparisons were conducted using rank sum test of number of peices of equipment and article and staff number in institutions at different levels in different regions. Results In 2023, the 353 radiological diagnostic institutions in Linyi were all equipped with radiological diagnostic equipment, summing 1 180 pieces. The median value M (P25,P75) of the number of peices of radiological diagnostic equipment possessed by each diagnostic institution was 2 (2, 3). The highest proportion of a single piece of equipment was 35.4% for digital radiography (RD) machine and 32.5% for computed tomography (CT) scanner, respectively, followed by image intensifier fluoroscopes 7.9% and flat-panel detector fluoroscopes 7.6%, while computed radiography(CR), 3 kinds of breast X-ray machines, 4 kinds of dental CT machines, and bone densitometers accounted for less than 4.0% each. A total of 223 items of protection equipment (radiation monitoring devices) were equipped, about of 47.0%. The radiological diagnostic institution was each equipped with protective articles. A total of 5 709 protective articles were provided, mainly including lead rubber neck covers, lead rubber hats, and lead rubber aprons (accounting for over 20% each). In 2023, there were a total of 2 677 staff engaged in radiological diagnosis in Linyi, with the majority being male (62.9%). The M (P25, P75) of staff was 3 (2, 5), including 2 (1, 4) males and 1 (0, 2) females. There were level differences in radiological diagnostic equipment (χ2=109.04, P<0.05), protective articles (χ2=83.05, P<0.05), and the number of staff (χ2=96.90,P<0.05), with tertiary institutions significantly higher than other levels. In 2023, there were 107.8 pieces of radiological diagnostic equipment per million population (38.2 DR units and 35.0 CT scanners per million population) and 244 radiological diagnostic staff per million population (154 males and 90 females per million population) in Linyi. The exposure frequencies of radiological diagnosis in Linyi were 543.7 examinations per thousand population, with CT diagnosis having the highest frequency (342.7 examinations per thousand population), followed by X-ray photography (157.8 examinations per thousand population) during the survey period. Conclusions In 2023, all the radiological diagnostic institutions in Linyi are equipped with diagnostic equipment and protective articles. The number of CT, DR, breast DR units possessed by every millions of population are higher than the national and Shandong provincial average levels. The overall radiological diagnostic resources are generally good. However, the allocation of radiological diagnostic resources is unbalanced to a certain degree, which currently mainly focuses on the tertiary institutions. At the same time, the bone density meters and breast X-ray machines are insufficient, and further adjustments and optimizations are needed in the future. |
