Chapter 4: Case-Based Learning (CBL)
Case-Based Learning (CBL) is an educational strategy that uses clinical cases to bridge the gap between theoretical knowledge and real-world application. It is particularly relevant in surgical education, where clinical reasoning and decision-making are vital. This chapter explores the distinction between Problem-Based Learning (PBL) and Case-Based Learning (CBL) in surgery, provides guidelines for designing effective case-based discussions, and highlights the outcomes of CBL in developing clinical reasoning skills.
Section 4.1: Distinction Between PBL and CBL in Surgery
While both PBL and CBL utilize real-world problems to enhance learning, they differ in their structure, focus, and application in surgical education.
•Focus:
PBL: Encourages students to identify and explore the problem themselves, promoting self-directed learning.
CBL: Provides a structured case with specific questions, focusing on clinical reasoning and application of knowledge.
•Structure:
PBL: Starts with minimal information, allowing students to generate hypotheses and decide what information to gather.
CBL: Provides comprehensive case details upfront, guiding students through the diagnostic and management process.
•Role of Educator:
PBL: The educator acts as a facilitator, intervening minimally.
CBL: The educator plays an active role in guiding discussion and emphasizing key learning points.
Practical Example:
•PBL Scenario: "A 65-year-old man presents with abdominal pain. What questions would you ask, and what tests would you order?"
•CBL Scenario: "A 65-year-old man presents with abdominal pain. The CT scan reveals an abdominal aortic aneurysm. Discuss the management options and surgical intervention."
Section 4.2: Designing Effective Case-Based Discussions
Designing engaging and impactful CBL sessions requires careful planning and alignment with learning objectives.
•Step 1: Select or Develop Relevant Cases
Choose cases representative of common or critical surgical conditions (e.g., appendicitis, hernias, trauma).
Ensure the case aligns with curriculum objectives and challenges students to think critically.
•Step 2: Structure the Case Discussion
Case Presentation: Present a clinical scenario, including patient history, examination findings, and investigation results.
Guiding questions: Frame questions around diagnosis, differential diagnosis, investigation interpretation, and management.
Key Teaching Points: Highlight important takeaways such as diagnostic pitfalls or treatment nuances.
•Step 3: Facilitate the Session
Please encourage students to actively participate, share their reasoning, and justify their decisions.
Use probing questions like, “What if the patient had a history of anticoagulant use? How would your management change?”
Summarize key points at the end of the session to reinforce learning.
•Step 4: Incorporate Multimodal Resources
Use images, videos, or real patient data (with consent) to make cases more engaging. For instance, a case of gallbladder disease can include ultrasound or surgical footage.
Practical Example:
A CBL session on “Management of a Breast Lump” could include the following:
Case: A 45-year-old woman with a palpable lump in her right breast for three months.
Discussion Points: Differential diagnosis, interpretation of mammography, biopsy techniques, and surgical options.
Outcome: Students learn to correlate clinical and imaging findings with management strategies.
Section 4.3: Outcomes of CBL in Clinical Reasoning Development
CBL has profound effects on enhancing clinical reasoning and decision-making skills in surgical trainees.
•Promotes Critical Thinking: By working through cases, students develop the ability to analyze complex scenarios, identify relevant data, and synthesize solutions.
•Enhances Diagnostic Accuracy: Discussing real-world cases helps trainees correlate symptoms, signs, and investigations to arrive at precise diagnoses.
•Bridges Theory and Practice: CBL connects foundational knowledge with its practical application, making it highly relevant to clinical settings.
•Encourages Reflective Practice: Post-discussion reflection on what was learned and how it applies to future cases fosters lifelong learning.
Challenges and Recommendations:
•Challenge: Passive learners may struggle to engage in discussions.
Recommendation: Assign roles within the group (e.g., lead discussant, scribe, critic) to ensure active participation.
•Challenge: Time constraints may limit case depth.
Recommendation: Use concise cases focusing on specific learning objectives.
•Challenge: Cases may lack realism if overly simplified.
Recommendation: Include real-world complexity, such as atypical presentations or patient comorbidities.
Summary and Takeaways
Case-based learning is an indispensable tool in surgical education, fostering the development of clinical reasoning and decision-making skills through structured, real-world scenarios.
Key Actionable Points
Differentiate between PBL and CBL to utilize each method effectively in surgical training.
Design structured and engaging CBL sessions with clear objectives, guiding questions, and real-world cases.

This completes the third episode of Case-based learning & Simulation-based training. In the upcoming episodes up to the 7th episode we will discuss the various teaching methodologies and from the 8th to 14th episodes will discuss the various assessment methods. I hope it is useful to all academically oriented faculties and you all will enjoy this series of blogs and podcasts on Surgical Education.
In our institution, we are regularly doing both case-based learning & simulation-based training classes regularly. We used to give triggers on a particular surgical problem few days before the class and in the class, each student should answer questions in turn regarding these case scenarios. We follow the flip class model in this case-based teaching classes. In simulation-based training, we are using high-fidelity manikin- Metiman- to train our students. We simulate hypovolemic shock in this manikin and train our students how to diagnose and treat a hypovolemic shock.
