贵阳市介入诊疗医务人员辐射防护用具使用现状及分析

目的了解贵阳市从事介入诊疗工作的医务人员辐射防护用具使用及维护现状,并分析其影响因素。方法对47名介入诊疗医护人员(医师、护士、放射技师)辐射防护用具使用情况进行现场观察,并对观察结果进行分析。结果介入诊疗医师、护士和放射技师在使用辐射防护用具的实际人次占应使用辐射防护用具总人次的比例平均为50%(104/208)、32%(41/128)、32%(13/40)。不同性别使用情况差异无统计学意义;不同职称对辐射防护用具的使用情况差异有统计学意义;高级职称介入诊疗医务人员在辐射防护用具的维护方面意识低于初、中级职称。结论介入诊疗医务人员辐射防护用具使用及维护的总体情况有待提高,放射卫生监督管理部门及开展介入诊疗工作的单位主管部门应加强介入诊疗医务人员辐射防护用具使用和维护方面的知识培训,提高辐射防护用具使用和维护的意识,并督促改善辐射防护行为。

Current situation and influencing factor analysis of radiation occupational protection of medical staff engaged in interventional diagnosis and treatment in Guiyang City of China

Objective To investigate the current situation of the use and maintenance of radiation protective equipment in medical staff engaged in interventional diagnosis and treatment in Guiyang City of China, and to analyze its influencing factors. Methods A total of 47 interventional medical workers, including doctors, nurses and technicians, were enrolled in this study. On-site observation of their use of radiation protective equipment was conducted, and the observation results were analyzed. Results The mean proportions of the number of people who actually used radiation protective equipment to the total number of people who should use radiation protective equipment during interventional procedure in interventional doctors, nurses and technicians were 50%(104/208), 32%(41/128) and 32%(13/40) respectively. No statistically significant differences in the use of protective equipment existed between medical workers of different genders. The differences in the use of protective equipment between medical workers with different medical titles were statistically significant. The awareness degree of the maintenance of radiation protection equipment in the interventional staff with senior professional titles was lower than that in the interventional staff with junior or intermediate professional titles. Conclusion In aspect of the use and maintenance of radiation protective equipment in interventional medical workers, the current general situation needs to be improved. The radiation hygiene supervision and administration department and the department in charge of medical therapy units where the interventional diagnosis and treatment are carried out should strengthen the knowledge training on the use and maintenance of radiation protective equipment for medical staff engaged in interventional diagnosis and treatment, improve the awareness of the use and maintenance of radiation protection equipment, and urge the interventional staff to improve their radiation protection behavior.
