惠州市放射诊疗频度的调查与分析

目的 掌握惠州市开展放射诊疗的医疗机构基本情况及放射诊疗频度水平，科学实施医疗机构放射诊疗防护管理，提高放射卫生监督管理水平。方法 按照《广东省2017年医疗卫生机构医用辐射防护监测工作方案》的要求，对惠州市开展放射诊疗活动的医疗机构进行普查和现场核查。采用EXCEL表格对调查数据进行统计分析，根据惠州市《2017年统计年鉴》中2016年常住人口计算放射诊疗频度。结果 惠州2016年总的放射诊疗应用频度为482.68人次/千人口，其中放射诊断应用频度为478.29人次/千人口，介入诊疗应用频度为1.76人次/千人口，核医学诊疗应用频度为2.48人次/千人口，放射治疗应用频度为0.16人次/千人口。结论 惠州市放射诊疗机构的分布、放射诊疗设备和放射工作人员的配置不均衡。惠州市2016年的放射诊疗频度明显高于1998年惠州市、广东省和全国的放射诊疗频度，低于1998年周边城市深圳市、东莞市、广州市的放射诊疗频度。

Investigation and analysis of the frequency of radiological diagnosis and radiotherapy in Huizhou

Objective To master the basic situation of radiological diagnosis and treatment in Huizhou and the frequency of radiological diagnosis and radiotherapy, scientifically implement the radiation protection management of medical institutions, and improve the level of radiation hygiene supervision and management. Methods According to the requirements of the "Medical radiation protection monitoring program of medical and health institutions in Guangdong Province in 2017", we carried out the general survey and on-site verification of the medical institutions providing radiological diagnosis and treatment in Huizhou. The EXCEL table was used to analyze the survey data, and the frequency of Radiology and treatment was calculated according to the 2016 resident population from the《2017 statistical yearbook》of Huizhou. Results In 2016, the total frequency of radiation diagnosis and treatment was 482.68 person time/thousand people, of which, the frequency of radiological diagnosis is 478.29 person time/thousand people, the frequency of interventional diagnosis and treatment was 1.76 person time/thousand people, the frequency of nuclear medicine diagnosis and treatment was 2.48 person time/thousand people, and the frequency of radiation therapy was 0.16 person time/thousand people. Conclusion The distribution of the institutions offering radiological diagnosis and treatment institutions in Huizhou, the distribution of radiological diagnosis and treatment equipment and the staffs of radiological workers are uneven. The frequency of radiological diagnosis and treatment in Huizhou in 2016 was significantly higher than that in Huizhou, Guangdong and the whole country in 1998, but lower than that in the neighboring cities as Shenzhen, Dongguan and Guangzhou in 1998.
