Effectiveness of case-based teaching of cardiovascular physiology in clinical pharmacy students

Abstract

Objective: This study aimed to formulate and implement a case-based cardiovascular physiology module for second year clinical pharmacy (CP) students. We also evaluated the students’ feedback and compared the academic performance between a case-based teaching (CBT) group and a traditional didactic lectures (TDL) group. Methods: This descriptive quantitative study was conducted on 181 students who were divided into two groups. Group 1 (77 students) underwent TDL and the same topics were delivered to Group 2 (94 students) through CBT. A written examination was conducted at the end of both modules. A validated questionnaire was used to obtain feedback from the CBT group regarding CBT and their assessment grades (response rate - 93.6%). Results: Students’ feedback about CBT was positive. The majority of students, 63 (72%), preferred learning and understanding through CBT, finding it an enjoyable experience. Participants stated that CBT stimulated critical thinking (67; 76%) and linked theory to practice (69, 78%). Furthermore, 70 (80%) preferred this type of teaching and assessment in the future and 70 (80%) agreed to include CBT in all preclinical subjects. Students feedback was supported by exam results: the mean percentage of exam scores in the CBT group was significantly higher in comparison to the TDL group (81.2% vs. 79%, p value <0.05). Further comparison within the CBT group revealed improved student performance in “casebased” as compared to “conventional” questions (82.75% vs. 80%, p value <0.05). Conclusion: Students greatly appreciated CBT, as it stimulated logical thinking and active participation in the class, resulting in improved performance in exams.
