ABSTRACT Many physicians, particularly those practicing in remote regions, lack training opportunities to develop point-of-care ultrasound (POCUS) skills. This pretest-posttest study quantified the skill improvement of learners after participating in a virtual training program that used real-time, remotely delivered point-of-care tele-ultrasound (tele-POCUS) for teaching and learner feedback provision. Ten physicians practicing in an urban tertiary (Kingston, Ontario, Canada, n = 6) or remote care center (Moose Factory, Ontario, Canada, n = 4) completed a 3-week educational program that consisted of e-learning module review, independent image acquisition practice, and expert-guided tele-POCUS consultations. Pretraining and posttraining assessments were performed to evaluate skill enhancement in image acquisition, image quality, and image interpretation for cardiac and lung/pleura POCUS using a 5-point Likert scale. A total of 76 tele-POCUS consultations were performed during the study period. Significant improvements in image quality were noted following remotely delivered mentorship and guidance (all P < 0.01). In cardiac POCUS, pretraining and posttraining comparisons noted significant improvements in image acquisition (means, 2.69-4.33; P < 0.02), quality (means, 2.40-4.03; P < 0.01), and interpretation (means, 2.50-4.40; P < 0.02). In lung/pleura POCUS, significant improvements in image acquisition (means, 3.00-4.43; P < 0.01), quality (means, 3.23-4.37; P < 0.01), and interpretation (means, 3.00-4.40; P < 0.01) were demonstrated. Introductory ultrasound can be taught to novice users using a virtual, live-streamed training format with tele-POCUS while demonstrating significant enhancement in imaging skills.
