In this conversation, Daniel Belkin and Mitch Belkin interview infectious diseases physician and epidemiologist Dan Morgan, MD, about infection prevention, diagnostic stewardship, diagnostic reasoning, and medical overuse. They discuss regional differences in medical use and delve into a cluster-randomized controlled trial of contact precautions in ICU patients to evaluate whether this prevents C. Diff, MRSA, and VRE. They also touch on AI’s potential role in clinical decision support, and the question of how to improve clinician statistical reasoning.
