徐州市2013-2015年医疗照射水平调查分析

目的 了解和掌握徐州市放射诊疗水平和发展趋势，为合理配置放射诊疗资源及放射诊疗的监管提供科学依据，促进放射诊疗的合理发展。方法 以徐州市所有放射诊疗机构为调查对象，采用信访方式对全市放射诊疗机构进行调查。结果 本次共调查放射诊疗机构314家，2013-2015年徐州市放射诊疗设备和放射工作人员总数均不断增加，但每台设备占放射工作人员无明显变化，设备区域分布不均；徐州市医疗照射总频次呈上升趋势，其中核医学治疗增长最快。一级及其他医疗机构X射线诊断频次最多，放射治疗、介入放射学和临床核医学的照射主要集中于三级医疗机构。结论 徐州市放射诊疗资源在逐年增加，区域范围内资源分配不均，医疗照射水平呈逐年上升趋势，但是放射诊疗总体水平远低于苏南等经济发达地区。控制放射诊疗工作人员和公众的受照射剂量，做好医疗照射防护工作，是当前放射卫生监督的主要任务。

Investigation and analysis of medical irradiation level in Xuzhou City from 2013 to 2015

Objective To understand and master the status of radiation diagnosis and treatment as well as their development in Xuzhou City, to provide data basis for the rational allocation and supervision of radiation diagnosis and treatment, and to promot the rational development of radiation diagnosis and treatment.Methods Taking all radiation diagnosis and treatment institutions in Xuzhou as the survey object, using the letter and visit investigation method to carry out the survey.Results A total of 314 institutions were surveyed in Xuzhou City, both the number of device and radiation workers increased in 2013-2015, but the number of radiation workers for each piece of device did not obviously changed, and the regional distribution of device was uneven. The total frequency of medical uses of radiation was in the upward trend, with the fastest growth in nuclear medicine treatment. The frequency of X-ray diagnosis was highest in the Grade I and other hospitals, while radiotherapy, interventional radiology and clinical nuclear medicine were mainly concentrated in the Grade Ⅲ hospital.Conclusion The medical radiation resources increased year by year, but their regional distribution was uneven. The total frequency of medical uses of radiation also increased year by year, but the overall level was still much lower than the economically developed regions such as southern Jiangsu. Controlling the medical exposure to radiation workers and public and enhancing their protection have become the main tasks of radiological health supervision.
