Use of ultrasound as a diagnostic tool is fast becoming an expectation in clinical practice. With formal outcomes now being included as competencies in many residency programs, earlier exposure to use of ultrasound is being achieved through informal activities embedded within medical school curricula. Using ultrasound to learn anatomy is now standard practice for many courses in the United States. However, very few if any offer formal opportunities to assess student skill and anatomical knowledge at the same time. As part of the Mini Ultrasound Skills Institute (MUSI) in Anatomy, a component of the first year anatomy course, students were expected to complete a team‐based, hands‐on ultrasound skills assessment. Throughout the course, students received both didactic briefing sessions and hands‐on training on ultrasound basics, image interpretation, and scanning techniques. The ultrasound content was presented in parallel to anatomy and radiology curriculum. In the past, ultrasound knowledge was assessed via static images; however, due to the contextual nature of ultrasound interpretation, a live, hands‐on method was devised to assess student learning. At regular intervals during the course, students completed an ultrasound skills assessment. In their dissection teams of four, students completed four tasks: setup the machine, obtained, oriented, and labeled a desired image using a live model. Each student was given a unique role within this exercise. Students were graded on a rubric scale for each of the four components and given an overall team score. At the conclusion of the course, students completed a graded ultrasound objective structural practical examination (OSPE). Rotating through four stations, students completed the four tasks on four different structures. Students rotated through roles within their team as they moved between stations. OSPE grade was incorporated into their final laboratory practical grade. Preliminary data from formative OSPE assessments ‐‐‐‐showed an average score of 72% (±21%) with a minimum of 50%, maximum of 100%. Within the skill specific breakdown, students were very comfortable at labeling obtained images (100%) and had the most challenging time with either selecting the correct probe or setting up the scanner 40% (±51%). Overall, team‐based OSPE is an effective method to promote and evaluate ultrasound skills learned in an anatomy course.
