| 目的 调查黑龙江省放射诊疗机构开展常规X射线诊断和CT诊断的总人次，研究黑龙江省放射诊疗检查频度和诊断受检者的分布特点，统计全省医用X射线诊断应用频度。方法 以卫生计生行政部门文件形式，向黑龙江省所有放射诊断机构下发医疗机构基本情况调查表，结合现场抽样调查，收集并汇总全省2016年常规X射线诊断（不含介入放射学）、CT诊断的基本情况和诊疗人次。将调查结果参照2016年全省常住人口数，获取黑龙江省医用X射线诊断应用频度调查结果。结果 共调查1 645家医用辐射机构，其中三级医院81家，二级医院359家，一级及未定级医院808家，私人口腔诊所397家。这些医疗机构共进行常规X射线诊断7 706 050人次，CT诊断7 063 734人次。常规X射线诊断应用频度为200.9人次/千人口，CT诊断应用频度为184.1人次/千人口，总频度范围为98.0~274.7人次/千人口。全省公立医疗机构诊断频度是民营医疗机构的7.47倍。结论 黑龙江省放射诊断总人次分布中三级医院占据50%，而一级以下医疗机构只占13%。同时，公立与民营医疗机构数量虽然在同一量级，但公立医院的放射诊断总人次是民营医院的7倍以上。黑龙江省2016年常规X射线诊断和CT诊断应用频度与江苏省2015年调查结果基本相近。 |

| Objective To investigate the total examinations of conventional X-ray diagnosis and CT diagnosis of radiation diagnosis and treatment institutions, in order to explore the distribution characteristic of radiological diagnosis frequency and diagnostic patients, and to estimate the application frequency of medical X-ray diagnosis in Heilongjiang province. Methods The questionnaire was sent to all radiation diagnosis and treatment institutions in forms of public document issued by the administrative department of health and family planning of Heilongjiang province. Basic situations and patient numbers of conventional X-ray diagnosis (interventional diagnosis not included) and CT diagnosis in 2016 were collected and summarized combined with sampled on-site verification. The application frequency of medical X-ray diagnosis was obtained using permanent resident population in Heilongjiang province in 2016. Results Totally 1 645 medical radiation institutions were investigated, including 81 tertiary hospitals, 359 secondary hospitals, 808 primary hospitals or unrated medical institutions, and 397 private dental clinics. The examinations of conventional X-ray diagnosis and CT diagnosis were 7 706 050 and 7 063 734, respectively. The application frequency of conventional X-ray diagnosis and CT diagnosis was 200.9 and 184.1 examinations per 1 000 population, respectively, and varied from 98.0 to 274.7 in different areas. The ratio of examinations in public medical institutions to that in private medical institutions was 7.47:1. Conclusions 50% of the total radiological diagnosis were made in tertiary hospitals, and only 13% were made in medical institutions below primary in Heilongjiang. Meanwhile, although the number of public and private medical institutions was at the same scale, the total examination of radiological diagnosis in public medical institutions was 7 times of that in private medical institutions. The application frequency of conventional X-ray diagnosis and CT diagnosis in Heilongjiang province in 2016 was similar to that of Jiangsu province in 2015. |
