Exploration of the changes in the perceptions of medical students about cadaver dissections using metaphors

Abstract

Objective: This study examines the changes in metaphors used by medical students before and after the dissection of a cadaver. This will help qualitatively understand the meaning of cadaver dissections. Methods: The metaphorical expressions about the practice of dissection that were used before and after the dissection exercises were collected from 147 Korean medical students. The collected qualitative data were categorised through a repeated comparative analysis. Results: The results of the analysis identified seven types of metaphors that were used before the dissection practice: ‘rite of passage’, ‘first step’, ‘precious opportunity’, ‘fog’, ‘hell’, ‘thrill’, and ‘double-edged sword’. After the cadaver dissection, nine types of metaphors were used: ‘introspection’, ‘hell’, ‘precious opportunity’, ‘treasure hunt’, ‘turning point’, ‘debt’, ‘mist’, ‘bittersweet candy’, and ‘buzzer beater’. In general, before a cadaver dissection, students recognised the importance of the practice of cadaver dissection as being a ‘gateway’ or a ‘growing pain’. Metaphors such as ‘introspection’ and ‘mirror’ were used with an improved attitude. However, some students continued to use negative metaphors, such as ‘hell’, before and after the cadaver dissection and maintained negative feelings about it. Conclusions: The results of our study suggest that, for many medical students, cadaver dissection is a crucial stage of self-reflection and for the formation of their identities as doctors. The consideration of students’ perceptions during all cadaver dissections is therefore essential.
