摘要
目的对北京市东城区放射诊断人员X射线影像诊断过程中的相关防护知识、信念和行为进行调查,分析相关影响因素,为提高放射防护意识提供参考依据。方法于2018年6—7月,采用整群抽样的方法,选取北京市东城区参加2018年复训的320名放射诊断人员为调查对象,采用知信行问卷进行调查,应用多因素logistic回归分析影响知信行的因素。结果调查共发放问卷320份,回收有效问卷305份,问卷有效率95.31%。调查对象中主要是通过培训班获取放射卫生防护知识的人数为275人,占90.16%,认为自己的放射防护知识已经足够的人数为211人,占75.46%,但有关射线敏感器官、X线防护目的、X线防护方法、胸片辐射剂量和患者年剂量限值5个问题的知晓率<50%。放射诊断工作人员防护相关知识及格人数为163人,及格率为53.44%;信念及格人数为188人,及格率为61.64%;行为及格人数为196人,及格率64.26%。多因素logistic回归分析显示,工龄和医疗机构级别是防护知识得分的独立影响因素;文化程度和医疗机构级别是信念得分的独立影响因素;职称、知识和信念得分是否及格是防护行为得分的独立影响因素。结论北京市东城区放射诊断工作人员对辐射防护相关知识知晓率分布不均衡,行为形成率不高,应通过强化放射人员培训和加强医疗机构监管等手段,提高放射工作人员防护意识。
Objective To investigate the knowledge,attitude and practice of radiation protection during the process of X-ray imaging diagnosis among radiodiagnosis workers in Dongcheng District of Beijing,analyze the related influencing factors,provide reference for improving the awareness of radiation protection.Methods Totally 320 radiodiagnosis workers in Dongcheng District,who attended radiation protection training in 2018,were collected by the cluster sampling between June and July 2018.The questionnaire of knowledge,attitude and practice was used to investigate,and multivariate logistic regression was used to analyze the influencing factors.Results A total of 320 questionnaires were distributed and 305 valid questionnaires were recovered,with an effective rate of 95.31%.Among the respondents,275 acquired the knowledge of radiation protection through the training course,accounting for 90.16%.211 respondents thought they had enough knowledge of radiation protection,accounting for75.46%,however,the awareness rates of five questions about sensitive organs,purpose of X-ray protection,methods of X-ray protection,radiation dose of chest X-ray and annual dose limit of patients were less than 50%.163 radiodiagnosis workers passed the related knowledge examination,with a passing rate of 53.44%.188 passed the examination for attitude with a passing rate of61.64%.196 passed the practice examination,with a passing rate of 64.26%.Multivariate logistic regression analysis showed that length of service and level of medical institutions were independent influencing factors of protection knowledge score,education level and medical institution level were independent influencing factors of attitude score,and professional title,knowledge and attitude scores were independent influencing factors of protective behavior score.Conclusion The awareness rate of radiation protection related knowledge is uneven and the behavior formation rate is not high among radiodiagnosis workers in Dongcheng District of Beijing.It is necessary to strengthen the training of radiation workers and the supervision of medical institutions to improve the protection awareness of radiation workers.
