title: Impact of the clinical ultrasound elective course on retention of anatomical knowledge by second-year medical students in preparation for board exams.
abstract: Ultrasound has been integrated into a gross anatomy course taught during the first year at an osteopathic medical school. A clinical ultrasound elective course was developed to continue ultrasound training during the second year of medical school. The purpose of this study was to evaluate the impact of this elective course on the understanding of normal anatomy by second-year students. An anatomy exam was administered to students enrolled in the clinical ultrasound elective course before the start of the course and after its conclusion. Wilcoxon signed ranks tests were used to determine whether exam scores changed from the pre-test to the post-test. Scores from two classes of second-year students were analyzed. Students who took the elective course showed significant improvement in the overall anatomy exam score between the pre-test and post-test (P < 0.001). Scores for exam questions pertaining to the heart, abdomen, upper extremity, and lower extremity also significantly improved from the pretest to post-test (P < 0.001), but scores for the neck and eye showed no significant improvement. The clinical ultrasound elective course offered during the second year of medical school provided students with an important review of key anatomical concepts while preparing them for board exams. Our results suggested that more emphasis should be placed on head and neck ultrasound to improve student performance in those areas. Musculoskeletal, abdominal, and heart ultrasound labs were more successful for retaining relevant anatomical information.
