Across residencies, there is marked variability in US training. The \u201cgoal\u2010directed focused US\u201d part of the Milestones Project states that trainees must correctly acquire and interpret images to achieve a level 3 milestone. Standardized methods by which programs teach these skills have not been established. Our goal was to determine whether residents could achieve level 3 with or without a dedicated US rotation.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Thirty\u2010three first\u2010 and second\u2010year residents were assigned to control (no rotation) and intervention (US rotation) groups. The intervention group underwent a 2\u2010week curriculum in vascular access, the aorta, echocardiography, focused assessment with sonography for trauma, and pregnancy. To test acquisition, US\u2010trained emergency medicine physicians administered an objective structured clinical examination. To test interpretation, residents had to identify normal versus abnormal findings. Mixed\u2010model logistic regression tested the association of a US rotation while controlling for confounders: weeks in the emergency department (ED) as a resident, medical school US rotation, and postgraduate years.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>For image acquisition, medical school US rotation and weeks in the ED as a resident were significant (<jats:italic>P<\/jats:italic>\u2009=\u2009.03; <jats:italic>P<\/jats:italic>\u2009=\u2009.04) whereas completion of a US rotation and postgraduate years were not significant.

A dedicated US rotation did not have a significant effect. A medical school US rotation had a significant effect on image acquisition but not interpretation.
