Background: Case-based learning (CBL) is a contextualized learning and teaching method that can facilitate active and reflective learning to develop critical thinking and problem-solving skills. However, nursing educators have some difficulty in creating a CBL environment that matches the diverse professional nursing curriculum and students' needs, including developing relevant cases and appropriate CBL implementation processes.
Objective: To summarize the case design, implementation process, and their relationship with CBL effectiveness.
Methods: Electronic databases of PubMed, Embase, Web of Science, CINAHL, China National Knowledge Infrastructure (CNKI) and Wanfang Data (a Chinese database) were searched from inception until January 2022. Study quality was assessed using the Mixed Methods Appraisal Tool. A qualitative synthesis was then conducted to summarize the study findings.
Results: The systematic mixed studies review included twenty-one quantitative studies, five qualitative studies and two mixed methods studies. The case design and implementation process were indispensable parts of each study, but the application process of CBL in each study was slightly different, basically including case design, preparation, small-group interaction and exploration, collaborative efforts, teacher summary, assignment and teacher feedback. There were three themes in this review that indicate the effect of CBL on students, namely, knowledge, competence and attitude.
Conclusion: The present review analyzes the available literature and suggests that there is no common format for the case design and CBL implementation process, but demonstrates that they are an indispensable part of each study. This review provides conceptual procedures for nurse educators to design and implement CBL in nursing theoretical courses to improve the effectiveness of CBL.
