| 目的 通过对江苏省4个县（区）抽样医院的放射诊断设备进行频度调查，研究江苏省放射诊断检查频度和诊断受检者的分布特点，估算全省普通放射诊断和计算机X射线断层摄影装置（CT）检查的频度。方法 采用分层随机抽样方法，将江苏省分成3个片区，在每个片区中使用随机数字表法随机抽取4个设区市，每个设区市用随机数字表法随机抽取1个县区，将4个县区内所有公立医院作为样本医院，通过样本医院中的放射信息管理系统（RIS）获得医院的放射诊断设备在调查期间的受检者性别、年龄、检查类型、检查部位等分布信息，并对结果加以分析。结果 样本中37家医疗机构共调查受检者信息728 196条，其中普通放射诊断受检者信息479 024条，CT受检者信息249 172条。样本中受检者男女比例较为平均；年龄分布中"＞40"组占比例最高，为62%。虽然一级医院数量较多，占70%，但二级医院的放射诊断频次在总频度中占比较高。各种检查类型中钡灌肠、乳腺X射线摄影等专科检查多集中于三级医院。以此次调查结果估算江苏省全省2015年普通放射诊断频度达到303次/千人口，CT扫描频度达到173次/千人口。结论 自上次放射诊断频度调查以来，江苏省放射诊断的频度水平发展较快，为开展放射卫生工作提出了较大的挑战。因此，切实采取有力措施，加强医疗照射的防护，是当前十分重要的公共卫生问题。 |

| Objective To study the frequencies of diagnostic exposure and distribution of examined patients in Jiangsu province and to evaluate the frequencies of commom diagnostic exposure and CT examination by investigating public hospitals in Jiangsu.Methods Public hospitals in 4 counties (districts) were sampled, and the information of examined patients on sex, age, diagnostic type and exposure category were gathered through radiology information system (RIS) of the sampled hospitals.Results A total of 728 196 records of diagnostic procedures were gathered from the sampled hospitals. Among them 479 024 records were on common diagnostic procedures, whereas 249 172 records were on CT diagnostic procedures. The sex ratio was relatively balanced. the above 40 years of age group amounted for 62% the highest proportion, among the three age groups. The diagnostic frequencies in level Ⅱ hospitals contributed the highest proportion although 70% of the sampled hospitals were level I hospitals. Such diagnostic procedures as barium enema and mammography were highly distributed in level Ⅲ hospitals. Diagnostic frequencies were estimated in 2015 at 303 common diagnostic examinations and 173 CT diagnostic procedures per 1 000 persons in Jiangsu province.Conclusions Frequencies of diagnostic radiology in Jiangsu became increased since the last investigation of medical exposure examinations during the Ninth Five-year Plan, which was a challenge for health care. It is important to mobilize more resources in protection against medical radiation exposure. |
