Resident physicians who have completed the basic ultrasound courses each watch the same short instructional video and then perform three eFAST examinations on the same healthy volunteer. Participants are randomly assigned to one of three groups: (1) the instructional video only, with no live help; (2) the video plus real-time audio guidance from a remote expert who can see the live ultrasound image; or (3) the video plus guidance through a head-mounted device that also lets the expert see the participant's own point of view.\n\nAfterwards, experts who were not involved in a given exam review the recorded ultrasound images, without knowing which group the participant was in, and rate the image quality and skill. The study also measures how long the exams take, the participants' workload, and the comfort and usability of the system.\n\nThe goal is to learn whether real-time remote guidance, and in particular guidance through a head-mounted device, helps trainees produce better and faster eFAST examinations than an instructional video alone.",[99,100,101,102,103],"Clinical Competence","Ultrasonography","Medical Education","Point-of-care Ultrasound (POCUS)","Focused Assessment With Sonography for Trauma (FAST)",[105,106,107,108,109,110,111,112,113,114],"eFAST","POCUS","point-of-care ultrasound","tele-ultrasound","remote guidance","head-mounted device","simulation training","medical education","QUICk","OSAUS","NOT_YET_RECRUITING","2026-08-10",{"date":118,"type":119},"2026-08-12","ACTUAL",{"date":121,"type":93},"2026-08-17",{"date":123,"type":93},"2027-06",{"name":78,"class":6},1]
