OBJECTIVE: The aim of the study is to explore the application of safety education based on the IMB model to prevent harm caused by magnetic resonance ferromagnetic projection accidents. METHODS: One hundred ninety-six patients undergoing magnetic resonance imaging were divided into a control group of 90 cases and an observation group of 106 cases. The control group received routine safety education, while the observation group received safety education based on the IMB model in addition to routine education. The knowledge, attitudes, and behaviors related to the prevention of ferromagnetic projection accidents, as well as fear scores, were compared before and after the intervention. RESULTS: A total of 90 cases in the control group and 106 cases in the observation group completed the study. There were statistically significant differences in the scores of knowledges, attitudes, and behaviors related to the prevention of ferromagnetic projection accidents, as well as fear scores between the 2 groups after the intervention (all P <
0.01). CONCLUSIONS: Safety education based on the IMB model can improve the knowledge, attitudes, and behaviors of magnetic resonance imaging patients and reduce the risk of ferromagnetic projection accidents.
