北京市通州区公立与私立医院放射诊疗场所防护监测与分析

Monitoring and analysis of the radioprotection in radiology clinic sites of public and private hospitals in Tongzhou district of Beijing

目的比较北京市通州区公立医院与私立医院放射诊疗场所防护现况,为进一步提高该区医疗机构放射防护水平提供依据。方法按《医用X射线诊断放射防护要求》(GBZ 130—2013)要求,对该区上年度检测合格的19家公立医院和20家私立医院放射诊疗场所进行现场调查、检测。结果该区放射诊疗场所防护设施配置总符合率,公立医院(92.9%)高于民营医院(84.8%);场所外的周围剂量当量率检测点不合格率公立医院为1.6%低于民营医院的4.8%,上述指标差异均具有统计学意义(P<0.01)。结论公立医院放射诊疗场所防护总体水平高于私立医院,其主要原因是私立医院辐射防护最优化意识较公立医院差,但公立医院放射诊疗场所防护也存在不合格情况,在日常工作中两者都需提高防护最优化意识。

Objective To compare the radioprotection in radiology clinic sites of public and private hospitals in Tongzhou district of Beijing, in order to provide evidence for improving the levels of radioprotection in medical institutions. Methods The radiological sites of 19 public hospitals and 20 private hospitals, which already passed the test last year, were selected and tested again according to the Requirements for radiologieal protection in medical X-ray diagnosis （ GBZ 130 - 2013）. Results The coincidence rate of protection facilities in public hospitals was 92.9% compared with 84.8% in private hospitals, and the difference was significant （P 〈 0.01 ）. The unqualified rates of dose equivalent outside the detection points were also different in public and private hospitals （P 〈 0.01 ） , which were 1.6% and 4. 8% respectively. Conclusion The protection of radiotherapy clinics in public hospitals was better than that in private hospitals. The main reason was less awareness of radiation protection in private hospitals. However, some unqualified protection in public hospitals also existed. Both public and private hospitals should enhance optimizing protection consciousness in their daily work.
