Radiation accidents can cause numerous challenges to hospitals, the appropriate medical responses to which may save the lives of countless people. The present study aimed at the design and validation of an Emergency Department preparedness questionnaire for hospital emergency departments (EDs) in the case of radiation accidents, nuclear accidents, and nuclear terrorism in Iran.
This multistage cross-sectional study was conducted in 2019. The questionnaire items were created with the reference to article reviews and expert judgement. The validity of the questionnaire was assessed through face, content, and construct validities. Additionally, its reliability was estimated using measures of internal consistency and stability, namely Cronbach's alpha and intraclass correlation coefficient (ICC). To this end, the questionnaire was completed by the ED staff in the hospitals of Iran.
The proposed 48-item questionnaire consisted of three themes: staff preparedness, stuff preparedness, and structure preparedness. The face and content validities were confirmed by expert judgement. All items remained with content validity ratio (CVR) > 0.7 and the mean content validity index (CVI) = 0.891. The overall Cronbach's alpha and ICC were 0.781 and 0.709, respectively for the whole questionnaire.
Hospital ED preparedness in radiation and nuclear accidents requires readiness of staff, stuff, and structure of the ED, the consideration of which will properly respond to radiation and nuclear accidents. Thus, upstream organizations like the Ministry of Health and the Emergency Organization should oblige hospital EDs to make themselves be more prepared by codifying certain imperative laws and -policies.
辐射事故会给医院带来诸多挑战，而采取适当的医疗应对措施可能会拯救无数人的生命。本研究旨在设计并验证一份针对伊朗辐射事故、核事故和核恐怖主义的医院急诊科（ED）准备情况的调查问卷。
这是一项 2019 年进行的多阶段横断面研究。问卷项目的创建参考了文献回顾和专家意见。通过表面效度、内容效度和结构效度来评估问卷的有效性。此外，还通过内部一致性和稳定性测量（Cronbach's alpha 和组内相关系数 [ICC]）来评估其可靠性。为此，伊朗医院的 ED 工作人员填写了这份问卷。
拟议的 48 项问卷包括三个主题：员工准备情况、物资准备情况和结构准备情况。专家判断证实了表面效度和内容效度。所有项目的内容效度比（CVR）均>0.7，平均内容效度指数（CVI）=0.891。整个问卷的总体 Cronbach's alpha 和 ICC 分别为 0.781 和 0.709。
医院 ED 在辐射和核事故中的准备工作需要 ED 的员工、物资和结构做好准备，这将有助于对辐射和核事故做出适当的应对。因此，卫生部和紧急组织等上游机构应通过制定某些必要的法律和政策，要求医院 ED 使自己做好更充分的准备。
