目的 了解某区放射诊疗人员现况，为加强监管提供技术依据。方法 对2016-2018年某区持有《放射诊疗许可证》的医疗机构进行问卷调查，调查内容包括辖区基本情况、放射诊疗单位及人员情况、放射工作人员证持证情况、个人剂量检测情况、职业健康检查情况等；统计方法采用χ²检验，以P<0.05为差异有统计学意义。结果 2018年某区放射诊疗单位共77家，《放射诊疗许可证》持证率100%，平均每万人拥有放射诊疗机构0.37家，放射诊疗人员665人，平均每万人拥有放射诊疗人员3.22人，自2016年以来均呈递增趋势。《放射工作人员证》持证率呈逐年递增趋势，2018年达到87.2%，差异有统计学意义（P<0.05）。个人剂量检测率2018年为94.3%，近两年分别下降3.2%、1.5%，差异有统计学意义（P<0.05）；其中非疾控机构承检比例逐年上升，差异有统计学意义（P<0.05）。职业健康检查体检率逐年递增，2018年达到97.6%，差异有统计学意义（P<0.05）；其中非公立机构承检比例呈下降趋势，差异无统计学意义（P>0.05）。结论 应进一步加强放射诊疗工作监管，合理配置放射诊疗机构和人员，保持个人剂量检测及职业健康监护的高覆盖率，大幅提高放射工作人员持证水平。

Objective To understand the current situation of radiological diagnosis and treatment personnel in a district and provide technical basis for strengthening supervision.Methods To conduct a questionnaire survey of medical institutions in a certain district that hold the Radiological diagnosis and treatment license from 2016 to 2018, including the basic conditions of the district, the conditions of the radiological diagnosis and treatment units and personnel, the certificate holders of the radiologist, the personal dose test, and the occupational health examination; The statistical method uses χ² test and the difference of P<0.05 is statistically significant.Results In 2018, there were a total of 77 radiological diagnosis and treatment units in a certain area, and the certificate rate of "radiological diagnosis and treatment license" was 100%, with an average of 0.37 radiological diagnosis and treatment institutions per 10 000 people on average, 665 radiological diagnosis and treatment personnel, and an average of 3.22 radiological diagnosis and treatment personnel per 10 000 people. Since 2016, there has been an increasing trend. The holding rate of radiology personnel certificate has been increasing year by year, reaching 87.2% in 2018, with a statistically significant difference (P<0.05). The individual dose detection rate was 94.3% in 2018, which decreased by 3.2% and 1.5% respectively in the past two years. The difference was statistically significant (P<0.05); Among them, the proportion of non-disease control institutions has increased year by year, and the difference is statistically significant (P<0.05). The physical examination rate of occupational health inspection increased year by year, reaching 97.6% in 2018, and the difference was statistically significant (P<0.05); Among them, the proportion of private institutions is declining, and the difference is not statistically significant(P>0.05).Conclusion It is necessary to further strengthen the supervision of radiological diagnosis and treatment, rationally allocate radiological diagnosis and treatment institutions and personnel, maintain the high coverage rate of individual dose testing and occupational health supervision, and substantially improve the certification level of radiological workers.
