Background And Objective:
Traditional point-of-care ultrasound (PoCUS) teaching that relies on hands-on practice faces challenges of limited scale and infection-control constraints during pandemics. We designed a low-contact curriculum integrating near-peer teaching (NPT) with faculty remote supervision (RS) and evaluated its effectiveness versus on-site faculty-led teaching.
Methods:
In this randomized controlled pilot trial, 69 senior medical students were assigned to NPT+RS (n=34) or faculty-led control group (n=35). Both groups received identical didactic and hands-on training, with the NPT+RS group incorporating multi-camara telemedicine supervision by the faculty to support NPT. The primary outcome was the Entrustable Professional Activity (EPA)-based Objective Structured Clinical Examination (OSCE) score with four major domains measured 1 month after training. The secondary outcomes included the technology acceptance model (TAM) survey and the OSCE feedback.
Results:
Total OSCE scores (74.9 vs 76.8; p=0.614) and the Indication-Acquisition-Interpretation-Medical decision domain scores did not differ between two groups. For single items, only a lower interpretation performance at the posterolateral alveolar/pleural syndrome in NPT+RS group (4.6 vs 6.5; p=0.013) was found. The NPT+RS group reported higher perceived usefulness (efficiency, usefulness, performance, productivity; all p<0.05), with no between-group difference in perceived ease-of-use. The OSCE was more often perceived by the NPT+RS group as revealing weaknesses (p=0.002) and meriting routine post-training implementation (p=0.034).
Conclusions:
A low-contact PoCUS curriculum integrating NPT with RS achieved overall EPA-based OSCE performance comparable to traditional faculty-led instruction while enhancing perceived usefulness and assessment acceptance. Implementation of this model allows for greater training capacity and decreased contact. The capacity of NPT for image-interpretation skills warrants investigation.
