We sought to quantify the knowledge base among parents and legal guardians presenting to our pediatric emergency department regarding radiation exposure during medical imaging and potential risks to children resulting from ionizing radiation. We sought to examine if a child's previous exposure to medical imaging changed caregiver knowledge base and discern caregivers' preference for future education on this topic.
A prospective convenience sample survey was performed of caregivers who presented with their child to our tertiary pediatric emergency department. Parents or legal guardians (18-89 years) who accompanied a child (0-17 years) were eligible for inclusion and approached for enrollment. A structured questionnaire was administered by trained interviewers, and a chart review was conducted to ascertain if their child had a history of previous imaging.
Sixty percent of caregivers interviewed (n = 205 of 340) did not associate any long-term negative effects with medical imaging. Among participants who did express a perceived risk from medical imaging radiation exposure, only 50% could indicate a known negative effect from exposure. We found no significant association between a child having had documented imaging studies and awareness of long-term negative effects (P = 0.22). Participants preferred to learn more about this topic from an Internet-based resource (50%), informational pamphlet (38%), or via treating physician (33%).
Parents and legal guardians are largely unaware that exposure to radiation during medical imaging carries an inherent risk for their child. Health care providers wishing to educate caregivers should utilize reliable Internet sources, educational pamphlets, and direct communication.
我们试图量化前来我院儿科急诊科就诊的家长及法定监护人关于医学影像检查时辐射暴露以及电离辐射对儿童潜在风险的知识储备。我们试图研究儿童既往接受医学影像检查的经历是否会改变照料者的知识储备，并了解照料者对于该主题未来教育方式的偏好。
对带孩子前来我院三级儿科急诊科就诊的照料者进行一项前瞻性便利抽样调查。陪伴儿童（0至17岁）前来就诊的家长或法定监护人（18至89岁）符合纳入标准，并被邀请参与研究。由经过培训的访谈者发放一份结构化问卷，并进行病历审查以确定其孩子既往是否有影像检查史。
接受访谈的照料者中有60%（340人中的205人）认为医学影像检查不会带来任何长期负面影响。在那些确实表示察觉到医学影像辐射暴露存在风险的参与者中，只有50%能够指出一种已知的暴露负面影响。我们发现儿童有影像检查记录与对长期负面影响的认知之间没有显著关联（P = 0.22）。参与者更倾向于通过网络资源（50%）、信息手册（38%）或主治医生（33%）来了解更多关于该主题的信息。
家长及法定监护人大多未意识到医学影像检查时的辐射暴露会给其孩子带来内在风险。希望对照料者进行教育的医疗保健提供者应利用可靠的网络资源、教育手册及直接沟通。
