BackgroundMorning report is a fundamental component of internal medicine training and often represents the most significant teaching responsibility of Chief Residents. We sought to define Chief Resident behaviors essential to leading a successful morning report.MethodsIn 2016, we conducted a multi-site qualitative study using key informant interviews of morning report stakeholders. 49 residents, Chief Residents, and faculty from 4 Internal Medicine programs participated. Interviews were analyzed and coded by 3 authors using inductive reasoning and thematic analysis. A preliminary code structure was developed and expanded in an iterative process concurrent with data collection until thematic sufficiency was reached and a final structure was established. This final structure was used to recode all transcripts.ResultsWe identified four themes of Chief Resident behaviors that lead to a successful morning report: report preparation, delivery skills, pedagogical approaches, and faculty participation. Preparation domains include thoughtful case selection, learning objective development, content editing, and report organization. Delivery domains include effective presentation skills, appropriate utilization of technology, and time management. Pedagogical approach domains include learner facilitation techniques that encourage clinical reasoning while nurturing a safe learning environment, as well as innovative teaching strategies. Moderating the involvement of faculty was identified as the final key to morning report effectiveness. Specific behavior examples are provided.ConclusionConsideration of content preparation, delivery, pedagogical approaches, and moderation of faculty participation are key components to Chief Resident-led morning reports. Results from this study could be used to enhance faculty development for Chief Residents.
