Assessment of Reasoning Tool.
Clinical reasoning can be flawed due to bias, fatigue, or knowledge deficits. This tool provides a five-component mechanism to help instructors assess students' diagnostic reasoning abilities and guide feedback (i.e., hypothesis-directed data gathering, articulation of a problem representation, formulation of a prioritized differential diagnosis, diagnostic testing aligned with high-value care principles, and metacognition. Faculty development videos are also provided to guide in use of the tool.
