摘要
目的调查介入放射工作人员防护现状及影响防护水平的有关因素。方法选取上海市某三级医院94名介入放射工作人员作为研究对象,收集其工作量、个人防护用品及辅助防护设施使用、个人剂量监测、职业健康检查、影响个人防护用品使用因素等信息。结果2017年心血管、肿瘤、神经介入诊疗工作量较大;个人防护用品中铅围裙使用率最高为100%,其次为铅围脖97%,铅防护眼镜、铅橡胶帽、铅橡胶手套、铅内裤的使用率较低,分别为52%、23%、10%、3%;铅悬挂防护屏(帘)、床侧防护屏(帘)及可移动铅屏风的使用率分别为84%、62%、69%;每次介入诊疗过程中均会佩戴个人剂量计人数占78%,铅衣内外均佩戴个人剂量计人数占49%;职业健康检查率为100%;六类介入放射工作人员中肿瘤介入工作人员个人防护用品及辅助防护设施综合使用率、个人剂量计佩戴率均最高。防护用品配置不平衡及对防护重视程度不同是导致不同介入诊疗放射工作人员间个人防护用品使用率存在差异的主要原因。结论医疗机构应加强辐射安全文化建设,进一步普及铅围脖及辅助防护设施的使用。
Objective To investigate the occupational radiation protection status and influencing factors.Methods A total of 94 interventional radiation workers in a tertiary hospital in Shanghai were enrolled by using a self-administered questionnaire survey,and the survey data included information on workload,the use of personal protective equipment and auxiliary protective equipment,personal dose monitoring,occupational health examination,factors affecting the use of personal protective equipment.Results In 2017,the workload of cardiovascular,tumor and neurological interventional procedures were relatively large.The use rate of lead apron was 100%,followed by lead collar 97%,while the utilization rates of lead protective glasses,lead rubber caps and lead rubber gloves were only 52%,23%,10%and 3%,respectively.The usage rate of ceilingsuspension shields,table-suspension shields and mobile lead barriers were 84%,62%and69%,respectively.The wearing rate of personal dosimeter was 78%,the number of staff wearing personal dosimeters inside and outside the lead clothing accounted for 49%.The rate of regular occupational health examination was 100%.The comprehensive utilization rate of personal protective equipment and auxiliary protective equipment and the wearing rate of personal dosimeter in tumor interventional workers were the highest.Unbalanced configuration of protective equipment and different awareness of protection were the main reasons for the difference in the use rate of personal protective equipment among different interventional radiologists.Conclusion The hospital should strengthen the construction of radiation safety culture,and further popularize the use of lead apron and auxiliary protective equipment.
