PAs and point-of-care ultrasound: A scoping review

Objective: Point-of-care ultrasound (POCUS) has rapidly emerged as a valuable tool in the bedside assessment of patients. This scoping review summarizes existing literature covering clinical use and educational integration of POCUS by physician assistants (PAs), with the overall goal of identifying gaps in POCUS research involving the PA profession. Methods: Keyword searches of PubMed, EMBASE, Medline, and Google Scholar were conducted. Studies assessing PA POCUS use or accuracy; those evaluating extent, method, or value of POCUS educational integration; and those assessing the effect of POCUS training interventions were included. Results: Of the 717 studies retrieved, 30 met inclusion criteria. Studies generally demonstrated that PAs can use a fairly wide range of POCUS applications with high accuracy, but that POCUS integration into PA programs remains limited because of a number of identified barriers. Conclusions: Machine availability and insufficient POCUS training and education opportunities limit widespread clinical use of POCUS by PAs.
