Diagnostic Reasoning


Diagnostic reasoning is central to the internal medicine clerkship. Sir William Osler described medicine as the science of uncertainty and an art of probability. We hope during this clerkship you will further develop the  skill set needed to reason through diagnostic uncertainty and balance the probability of a diagnosis in the care of your patients.

For each patient, you are expected to:

  • Build a differential diagnosis.

  • Commit to a working diagnosis.

  • Clearly articulate your diagnostic reasoning.
