BACKGROUND: Point-of-care-ultrasound (POCUS) training is expanding in undergraduate and graduate medical education, but lack of trained faculty is a major barrier. Two strategies that may help mitigate this obstacle are interprofessional education (IPE) and near-peer teaching. The objective of this study was to evaluate a POCUS course in which diagnostic medical sonography (DMS) students served as near-peer teachers for internal medicine residents (IMR) learning to perform abdominal sonography.
METHODS: Prior to the IPE workshop, DMS students participated in a train-the-trainer session to practice teaching and communication skills via case-based simulation. DMS students then coached first-year IMR to perform POCUS examinations of the kidney, bladder, and gallbladder on live models. A mixed-methods evaluation of the interprofessional workshop included an objective structured clinical exam (OSCE), course evaluation, and qualitative analysis of focus group interviews.
RESULTS: Twenty-four of 24 (100%) IMR completed the OSCE, averaging 97.7/107 points (91.3%) (SD 5.2). Course evaluations from IMR and DMS students were globally positive. Twenty three of 24 residents (96%) and 6/6 DMS students (100%) participated in focus group interviews. Qualitative analysis identified themes related to the learning environment, scanning technique, and suggestions for improvement. IMR felt the interprofessional training fostered a positive learning environment and that the experience complimented traditional faculty-led workshops. Both groups noted the importance of establishing mutual understanding of expectations and suggested future workshops have more dedicated time for DMS student demonstration of scanning technique.
CONCLUSION: An interprofessional, near-peer workshop was an effective strategy for teaching POCUS to IMR. This approach may allow broader adoption of POCUS in medical education, especially when faculty expertise is limited.
