Multiple cases in case-based learning: A qualitative description study

Abstract

Introduction: Case-based learning is widely used in health professions education to improve clinical learning, but little is known about how best to approach multiple cases in this active learning strategy. Our study explored dental student views of multiple case-based learning in oral pathology.

Materials and methods: Qualitative description informed the study design. Data were collected through semi-structured, individual interviews with twenty-one third- and fourth-year dental students who participated in multiple case-based learning seminars. Data were analysed using inductive, manifest thematic analysis.

Results: Themes were identified at approach and case levels. Approach-level themes included preparing students for clinical practice and board exams and maximising exposure (e.g., to lesions/conditions), knowledge application, and engagement within the time allotted for the learning session. Case-level themes included using challenging but manageable cases, linking cases to lecture content, providing the necessary clinical information to solve the cases, and ensuring that cases were authentic and common with non-typical presentations. Aspects of themes encompassed definitions of case characteristics, benefits, conditions of implementation, and recommendations for improvement.

Conclusion: Cases should be considered individually, collectively, purposefully, and contextually in multiple case-based learning. Evaluations of learning and behavioural outcome are needed to further establish the effectiveness of approaches and case characteristics in multiple case-based learning.
