#2105 Introduction: Physical examination remains an important method of breast cancer detection. Unfortunately, many health care professionals express concerns about missing breast lesions and current methods of teaching this essential skill are limited. Through an interdisciplinary collaboration, we created an immersive virtual patient to teach health professions students history-taking and breast examination skills.
 Methods: Fifteen physician's assistant (PA) and 13 medical students (MS) interacted with a mixed reality human (MRH, a computer avatar with a mannequin-based breast simulator) with a breast complaint (Figure 1).
 
 Students spoke to and touched the MRH to take a history and examine a simulated breast with two masses of differing size and consistency. Subjects were surveyed regarding the usefulness of the virtual teaching tool and composed a patient note documenting pertinent history and physical examination findings. Students received feedback regarding the content of their patient note (number of 17 essential content items documented) and on the completeness of their breast examination (percentage area covered) using a color-coded touch map.
 Results: Student feedback related to the utility of this virtual educational tool was positive. Students only documented a mean of 7.8±2.7 (range=4-15) essential content items in the breast history. The completeness of the breast exam was a mean of 82% (range=62% to 97%) of total breast area examined (Figure 2, green=area examined, red=area missed).
 
 More clinically experienced students (MS 3 and 4, N=9) performed better than those with no clinical experience (MS 1 and PA 1, N=19) in both history-taking (58% vs. 40%, p<0.05) and completeness of exam (90% vs. 84%, p<0.05). Fifty percent of students were able to locate at least one mass but only 14% were able to correctly document the location of both lesions.
 Conclusions: The simulated experience differentiated performance among students with varying levels of clinical experience and identified a need for improved teaching and greater practice among all students. MRH scenarios provide a less anxious learning environment for students to practice breast history-taking and examination. Citation Information: Cancer Res 2009;69(2 Suppl):Abstract nr 2105.
