2019年北京市东城区医疗机构放射工作人员管理现状调查

目的 了解医疗机构放射工作人员管理现状和水平，为加强监管提供依据。方法 统一设计调查表，把放射工作人员基本信息、培训、体检、持证、建档和个人剂量作为调查内容，统计方法使用χ²检验和方差分析，检验水准α = 0.05，P < 0.05为差异有统计学意义。结果 医院共有放射工作人员1209人，其中男性682人（56.4%），初级职称603人（49.9%），中级职称449人（37.1%），高级职称157人（13.0%），本科及以上学历826人（68.4%），不同医院放射工作人员的性别、职称和学历分布均不同，差异具有统计学意义（P < 0.001）；趋势性χ²检验结果显示，医院级别越高，放射工作人员职称和学历越高（P < 0.001）；放射工作人员培训率、个人剂量监测建档率和职业健康检查建档率均为100%，放射工作人员体检率和持证率分别为98.5%和99.6%，不同医院放射工作人员的体检率和持证率差异没有统计学意义（P > 0.05）；个人剂量监测率和频次率为100.0%和93.7%；集体年剂量和平均年剂量分别为201.55 mSv·人和0.17 mSv；不同医院的平均年剂量（P < 0.001）差异有统计学意义，三级医院放射学工作人员人均年剂量显著高于其他医院（P < 0.05），不同岗位的平均年剂量（P < 0.001）差异有统计学意义，放射治疗和核医学放射学工作人员人均年剂量显著高于其他岗位（P < 0.05）。结论 医疗机构应完善放射工作人员管理，加强放射工作人员个人防护和个人剂量监测工作。

A survey of management status of radiation workers in medical institutions in Dongcheng District,Beijing in 2019

Objective To understand the management status and level of radiation workers in medical institutions, and to provide a basis for strengthening supervision.Methods To design the questionnaire in a unified manner including the following contents: basic information, training, physical examination, certification, file and personal dose of radiation workers, statistical methods using χ² test and variance analysis, significant level α = 0.05, P < 0.05 was statistically significant.Results There were 1209 radiation workers in the hospital, including 682 males (56.4%), 603 people (49.9%) with junior professional titles, 449 people (37.1%) with intermediate professional titles, 157 people (13.0%) with senior professional titles, and 826 people (68.4%) with bachelor degree or above. The distribution of gender, professional title and educational background of radiological staff in different hospitals was different and the differences are statistically significant (P < 0.001); the trend χ² test results show that the higher the hospital level, the higher the titles and degree of the radiation workers (P < 0.001); The radiation staff training rate, personal dose monitoring filing rate and occupational health examination filing rate were all 100%. The radiation staff physical examination rate and certificate holding rate are 98.5% and 99.6%, respectively. There was no statistically significant difference between the physical examination rate and the certification rate of the staff in different hospitals (P > 0.05); The personal dose monitoring rate and frequency rate were 100.0% and 93.7%, respectively. The collective annual dose and the average annual dose were 201.55 mSv and 0.17 mSv, respectively. The difference in the average annual dose (P < 0.001) of different hospitals was statistically significant. The average annual dose of radiology staff in tertiary hospitals was significantly higher than that in other hospitals (P < 0.05). The difference in the average annual dose (P < 0.001) of different positions was statistically significant. The average annual dose of radiotherapy and nuclear medicine radiology workers was significantly higher than that of other positions (P < 0.05).Conclusion Medical institutions should improve the management of radiation workers and strengthen the monitoring of personal doses and personal protection.
