One-third of all healthcare dollars are wasted, primarily in the form of clinician-ordered unnecessary diagnostic tests and treatments. Medical education has likely played a central role in the creation and perpetuation of this problem. We aimed to create a curriculum for medical students to promote their contribution to high-value care conversations in the clinical environment. At a large university medical center between March 2017 and February 2018, we implemented a 3-phase curriculum combining multimodal educational initiatives with individual and group reflection for third-year medical students during their 12-week long Internal Medicine clerkship rotation. Students were asked to identify examples of clinical decision making that lacked attention to high-value care, propose solutions to the identified situation, and pinpoint barriers to the implementation of effective solutions using a structured reflection framework and then participate in a debrief debate with fellow students. To assess the curriculum, reflective narratives were coded by frequency and codes were compared with one another and with relevant high-value care literature to identify patterns and themes. In total, 151 medical students participated in phase 1 and 119 in phase 3. For phase 2, 126 reflective narratives (94.7% participation rate) comprised 226 problems, 280 solutions, and 179 barriers. When provided appropriate resources, medical students are able to identify relevant examples of low-value care, downstream solutions, and barriers to implementation through a structured reflection curriculum comprising written narratives and in-person debate.
