What features should a case-based practice exercise include to improve CDM skills?

• A. Build realistic vignettes with uncertainty, alternate plausible hypotheses, require justification for data ordering, and include debrief with learning points
• B. Use rigid, deterministic cases with no uncertainty
• C. Limit feedback to a single right answer
• D. Avoid debriefs after exercises

Answer: (A)

The idea behind effective case-based practice is to train clinical decision-making by simulating real patient care, where uncertainty and evolving information are the norms. Realistic vignettes with uncertainty force you to consider that more than one explanation could fit the data and to weigh competing possibilities rather than settling on a single, obvious answer. Presenting alternate plausible hypotheses helps you develop a robust differential diagnosis and management plan that remains adaptable as new information appears. Requiring justification for data ordering trains the reasoning about why you seek certain information first, how tests and data influence probability estimates, and how that sequencing affects decisions and patient safety. Including a debrief with explicit learning points cements what you did well, highlights cognitive biases, and translates reasoning into concrete clinical actions for future cases.

Rigid, deterministic cases with no uncertainty miss the essential practice of handling ambiguity. Limiting feedback to a single right answer suppresses reflective thinking and learning from missteps, and skipping debriefs removes a critical opportunity to articulate reasoning and extract actionable lessons.
