Objective: We assessed the impact of a workshop on first-year medicine residents (PGY1) shared decision-making (SDM) communication skill, risk-benefit education, and attitude.Methods: A SDM skills-focused workshop was integrated into an academic medical center PGY1 ambulatory rotation in 2016-2017. Pre/post recordings of virtual Objective Structured Clinical Examinations (OSCEs) with standardized patients sharing decisions were scored using OPTION5. Risk-benefit education, including decision aid use, was measured. Pre/post surveys assessed SDM practice attitudes and perceived barriers.Results: 31 of 48 (65%) PGY1 workshop attendees completed pre/post OSCEs yielding 62 videos. OPTION5 scores improved from 27/100 pre to 56/100 post (p < 0.001). Pre/post increases in integration of qualitative (15/31 vs 31/31, p < 0.001) and quantitative (3/31 vs 31/31, p < 0.001) risk measures, and decision aids (1/3 vs 31/31, p < 0.001) were observed. Pro-SDM attitude of decisional neutrality increased 16.6% pre to 71.9% post-survey (P < 0.001). Barriers to SDM remain. Conclusion: This PGY1 workshop with virtual OSCEs improved SDM communication skills, the ability to find and provide risk-benefit education, and SDM-facilitating attitude.Practice implications: Residency programs can improve SDM skills, risk-benefit education, and attitudes with a workshop intervention. Perceived time constraints and cognitive biases regarding risk-benefit es-timates should be addressed to ensure quality SDM in practice.(c) 2021 Elsevier B.V. All rights reserved.
