2016年度福建省医疗照射频度调查与分析

目的 通过对福建省的37家样本医院进行放射诊疗情况调查，研究福建省放射诊疗的基本情况，估算全省各类放射诊疗项目的照射频度。方法 采用全国统一的调查表，通过医院信息管理系统或手工登记本搜集样本医院的门急诊量、住院量、放射诊疗设备和放射工作人员的基本情况，以及各类诊疗项目的受检者性别、年龄、检查类型、检查部位等分布信息，并对调查结果进行统计分析。结果 37家医院各类放射诊疗项目合计照射人次4 496 833，基于该调查结果估算的福建省各类诊疗项目照射频度分别为X射线影像诊断459.1人次/千人口、介入放射学1.8人次/千人口、核医学2.4人次/千人口、放射治疗0.50例/千人口。结论 通过本次调查能够掌握福建省医疗照射频度的大体情况，可为我省放射诊疗技术的应用以及医疗照射防护安全提供许多的启发。

Investigation and analysis of medical radiation exposure frequency in Fujian Province in 2016

Objective Through the investigation of radiological diagnosis and treatment performed in the 37 sampled hospitals to estimate the application frequency of radiological diagnosis and treatment in Fujian.Methods Adopting the nationwide unified questionnaire, collect the information on the amount of outpatient and emergency patients, in-patients, radiological diagnosis and treatment equipment, radiological workers in the sampled hospitals through the hospital information system or the manually registering notebooks. The information of examinees were further counted by sex, age, diagnostic or treatment types and irradiation positions.Results The total number of medical radiation exposure in the 37 hospitals was 4 496 833 persons time. For per 1 000 population, the frequency of X-ray diagnosis, interventional radiology, nuclear medicine and radiotherapy were 459.1, 1.8, 2.4 and 0.50.Conclusion The general situation about the frequency of medical exposure in Fujian has been grasped throughout the investigation, and the results can provide many useful suggestions for both rational uses of radiological techniques and the protection and safety of medical radiation exposure.
