The value in the evidence: teaching residents to "choose wisely".

The Accreditation Council for Graduate Medical Education mandates that training physicians "incorporate considerations of cost awareness" into practice. However, medical education has traditionally avoided addressing costs, and most residency programs currently lack curricula to fulfill this requirement. With the recent widespread emphasis on unsustainable costs, inefficiencies, and waste in healthcare, the need to appropriately train physicians in this domain is increasingly apparent. In this article, we describe the implementation of a resident-led, case-based cost awareness curriculum for medicine residents at the University of California, San Francisco, sharing our keys to success and defining guiding principles.
