Learning Outcomes With Point-of-Care Ultrasound

July 15, 2019 updated by: Andre Kumar, Stanford University

Does Improved Access to a Portable Ultrasound Device Improve Trainee Learning With Point-of-care Ultrasonography: A Randomized Trial

Point-of care-ultrasonography has the potential to transform healthcare delivery through its diagnostic and therapeutic utility. Its use has become more widespread across a variety of clinical settings as more investigations have demonstrated its impact on patient care. This includes the use of point-of-care ultrasound by trainees, who are now utilizing this technology as part of their diagnostic assessments of patients. However, there are few studies that examine how efficiently trainees can learn point-of-care ultrasound and which training methods are more effective. The primary objective of this study is to assess whether handheld ultrasound devices, along with a year-long lecture series, improve internal medicine interns' knowledge and image interpretation skills with point-of-care ultrasound. Participants shall be randomized to receive personal access to handheld ultrasound devices to be used for learning vs. no personal access. The primary outcome will assess their interpretive ability with ultrasound images/videos. Secondary outcomes will include rates of device usage and lecture attendance.
