| 目的 分析我国数字X射线摄影(DR)设备状态检测初检合格率的影响因素,为明确下一步的全国医用辐射防护监测工作重点提供科学依据。方法 通过全国放射卫生信息平台—全国医用辐射防护监测系统,采集2020年全国31个省份上报的DR设备质量控制检测数据,采用logistic回归模型对DR设备状态检测初检合格率的相关影响因素进行分析。结果 logistic回归分析结果显示,放射卫生技术服务机构性质、医疗卫生机构级别和地区是DR设备状态检测初检合格率的独立影响因素(χ2=15.41~21.18,P < 0.05)。民营机构组(OR=1.714,95%CI:1.310~2.243)、三级医院组(OR=1.710,95%CI:1.310~2.232)和二级医院组(OR=1.540,95%CI:1.203~1.971)DR设备初检合格的概率较高,西部地区组(OR=0.670,95%CI:0.526~0.852)DR设备初检合格的概率较低。结论 应加强对DR设备质量控制检测的监督力度,建议加强检测设备的抽检和复核,重点关注西部地区和一级及未定级医院DR设备的质量控制检测。 |

| Objective To analyze the influencing factors on initial testing qualified rate of condition monitoring of digital radiography (DR) devices in China and provide the scientific basis for key points of national medical radiation protection monitoring work.Methods The data of quality control detection of DR devices, reported by 31 provinces in 2020, were collected from National Radiation Health Information Platform-National Medical Radiation Protection Monitoring System. Logistic regression was used to analyze the related influencing factors of initial testing qualified rate of condition monitoring of DR devices.Results The result of logistic regression analysis showed that the nature of radiological health technical service institutions, the level of medical and health institution and the regions where they are located in China were the independent influencing factors of initial testing qualified rate of condition monitoring of DR devices (χ2=15.41-21.18, P< 0.05). Private institution group (OR=1.714, 95%CI:1.310-2.243), tertiary hospital group (OR=1.710, 95%CI:1.310-2.232) and secondary hospital group (OR=1.540, 95%CI:1.203-1.971) had a higher qualified probability of DR devices, while western region group (OR=0.670, 95%CI:0.526-0.852) had a lower qualified probability of DR devices. Conclusions Supervision on quality control of DR devices should be strengthened, such as strengthening the random inspection and double-check to the devices. And great attention should be paid to the quality control testing of DR devices in the western China and in the primary and ungraded hospitals. |
