To evaluate the impact of a longitudinal ultrasound (US) simulation training program on radiology residents' comfort with performing and interpreting abdominal US.

Materials and Methods:
The longitudinal US curriculum includes online modules, case sessions utilizing a simulated US probe, and hands-on sessions with standardized patients. First, residents completed online modules covering US technique, anatomy, and pathology. A post-test was administered after each module to ensure an acceptable level of competence was achieved. In phase 2, residents completed case sessions using a US simulation probe to "scan" normal and abnormal cases. With manipulation of the US probe, images displayed were updated in real time, simulating an actual examination. In addition, the program gave feedback on the participant's manipulation of the probe. During this phase, each resident attended 2 case simulation sessions and completed 39 simulation cases. Feedback on the findings was provided immediately after the completion of each case. Phase 3 included a 75 minute simulation session with two standardized patients, an attending physician and a senior US technologist. An anonymous 11 question post-course survey with responses rated on a 5-point scale was administered electronically.

16 of 17 (94%) residents completed the survey (R1 37.50%, R2 31.25%, R3 12.50%, R4 18.75%). Prior to the US simulation curriculum, residents rated their comfort level at performing abdominal US as not at all confident (18.75%), not so confident (43.75%), somewhat confident (37.5%), very confident (0%), or extremely confident (0%). After the program, all residents rated their comfort level as very confident (31.25%) or somewhat confident (68.75%). On a 5-point Likert scale (1=strongly disagree, 5=strongly agree), median response regarding if the standardized patient sessions improved their comfort in scanning patients was 4.65, and the simulation US probe case sessions as improving their comfort in scanning patients as 3.14 and as improving their US knowledge as 4.00.

Implementation of a longitudinal US simulation curriculum improved radiology resident comfort with performing US exams, and can potentially improve diagnostic skills and patient safety. Planned additions include gynecologic/obstetric US and US-guided procedure modules.
