<b>Team-Based Analysis for Critical Thinking in Clinical Cases (TACTIC): Development of a new innovative method for teaching clinical reasoning</b>

Clinical reasoning is a core competency in undergraduate medical education, yet many instructional approaches do not fully address its cognitive complexity in a structured or scalable way. Team-Based Analysis for Critical Thinking in Clinical Cases (TACTIC) is a stepwise novel method that mirrors real-world diagnostic reasoning through iterative, team-based engagement with authentic clinical scenarios. This study describes the development of TACTIC using formal consensus methods.
