Teaching Clinical Reasoning in the Preclinical Period

Introduction: Developing the clinical reasoning skills necessary to becoming an astute diagnostician is essential for medical students. While some medical schools offer longitudinal opportunities for students to practice clinical reasoning during the preclin-ical curriculum, there remains a paucity of literature fully describing what that curriculum looks like. As a result, medical educators struggle to know what an effective clinical reasoning curriculum should look like, how it should be delivered, how it should be assessed, or what faculty development is necessary to be successful. We present our Introduction to Clinical Reasoning course that is offered throughout the preclinical curriculum of the Uniformed Services University of the Health Sciences. The course introduces clinical reasoning through interactive lectures and 28 case-based small group activities over 15 months. The curriculum is grounded in script theory with a focus on diagnostic reasoning. Specific emphasis is placed on building the student's semantic competence, constructing problem lists, comparing and contrasting similar diagnoses, constructing a summary statement, and formulating a prioritized differential diagnosis the student can defend. Several complementary methods of assessment are utilized across the curriculum. These include assessments of participation, knowledge, and application. The course leverages clinical faculty, graduate medical education trainees, and senior med-ical students as small group facilitators. Feedback from students and faculty consistently identifies the course as a highly effective and engaging way to teach clinical reasoning. Conclusion: Our Introduction to Clinical Reasoning course offers students repeated exposure to well-selected cases to promote their development of clinical reasoning. The course is an example of how clinical reasoning can be taught across the preclinical curriculum without extensive faculty training in medical education or clinical reasoning theory. The course can be adapted into different instructional formats to cover a variety of topics to provide the early learner with sequential exposure and practice in diagnostic reasoning.
