Students' perception of peer instructors' teaching competency was equivalent to faculty instructors for the majority of sessions. Senior students who have completed an elective ultrasound rotation may serve as a useful resource for circumstances where the availability of skilled instructors is limited. However, further research is required to evaluate their effectiveness.
The addition of ultrasound teaching to traditional physical examination instruction enhanced medical student competency and confidence with the femoral vascular examination. However, understanding of anatomy may require emphasis on precourse didactic material, but further study is required.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
