【摘要】：目的了解广州市一级医疗机构X射线诊断机房防护设施合格情况的分布特征。方法收集广州市2012-2016年140台一级医疗机构X射线诊断机房的防护设施现况,采用SPSS 21.0作秩和检验和卡方检验。结果机房防护设施总体合格率为17.14%,11项机房防护设施指标中,合格率最高为动力排风装置90.00%、最低为个人防护用品40.00%。不同X射线设备间总体合格率有统计学差异(χ2=28.349,P=0.000),DR机房最高(42.50%);双床双管类最低(0.00%)。对于合格率在不同类型X射线设备间有统计学差异的8项指标中,机房内最小单边长度、放射防护注意事项合格率最低的X射线设备均为双床双管单房(分别为50.00%和20.00%),机房布局和动力排风装置合格率最低的均为屏-片摄影(分别为62.50%和68.75%),个人防护用品、电离辐射警告标志、工作状态指示灯(灯箱处设警示语句)和门灯联锁合格率最低的均为双床双管双房(均为0.00%)。结论该市一级医疗X射线诊断机房防护设施现况不容乐观,特别是双床双管类和屏-片摄影。
[Abstract]:Objective to investigate the distribution characteristics of the qualified protective facilities in X-ray diagnostic machine rooms of first-grade medical institutions in Guangzhou. Methods to collect the prevention of X-ray diagnostic machine rooms of 140 first-grade medical institutions in Guangzhou from 2012 to 2016. Current status of security facilities. SPSS 21.0 was used for rank sum test and chi-square test. Results the overall qualified rate of protective facilities in computer room was 17.14 out of 11 indexes. The qualification rate was 90.00g for power ventilation device and 40.00g for personal protective equipment. There was statistical difference among different X-ray equipments (蠂 ~ 22.28. 349). The highest value of Dr machine room was 42.50%; The minimum one-sided length of the machine room for the 8 indexes with statistical differences in the qualified rate among different types of X-ray equipment was obtained. The X-ray equipments with the lowest qualified rate of radiation protection items were two-bed double-tube single room (50.00% and 20.00, respectively). The lowest qualified rate of engine room layout and power ventilation equipment were screen-film photography (62.50% and 68. 75, respectively), personal protective equipment, ionizing radiation warning signs. The working state indicator (warning statement at the light box) and the lowest pass rate of the door lamp interlock are both double bed and double tube double room (both 0.00000). Conclusion the present situation of the first class medical X-ray diagnostic machine room protection facilities in the city is not optimistic. In particular, two-bed double-tube and screen-film photography.
