“…In a prospective randomized trial, Celebi et al showed similar teaching effectiveness for student tutors and ultrasound experts [3], so our aim was to provide a first evaluation of the effectiveness of a mobile app without a tutor’s supervision. The results add to the observations of Celebi et al and others by showing positive effects after 60 minutes of autonomous practicing [15-17]. As opposed to Celebi et al [3] and Ritter et al [16], our study focused on practicing motor skills by using a smartphone or tablet.…”

Background Medical education is evolving from "learning by doing" to simulation-based hands-on tutorials. Objective The aim of this prospective 2-armed study was to evaluate a newly developed augmented reality ultrasound app and its effect on educational training and diagnostic accuracy. Methods We recruited 66 medical students and, using imaging and measuring a kidney as quality indicators, tested them on the time they needed for these tasks. Both groups used textbooks as preparation; in addition, the study group had access to a virtual ultrasound simulation app for mobile devices. Results There was no significant difference between the study arms regarding age ( P =.97), sex ( P =.14), and previous ultrasound experience ( P =.66). The time needed to complete the kidney measurements also did not differ significantly ( P =.26). However, the results of the longitudinal kidney measurements differed significantly between the study and control groups, with larger, more realistic values in the study group (right kidney: study group median 105.3 mm, range 86.1-127.1 mm, control group median 92 mm, range 50.4-112.2 mm; P <.001; left kidney: study group median 100.3 mm, range 81.7-118.6 mm, control group median 85.3 mm, range 48.3-113.4 mm; P <.001). Furthermore, whereas all students of the study group obtained valid measurements, students of the control group did not obtain valid measurements of 1 or both kidneys in 7 cases. Conclusions The newly developed augmented reality ultrasound simulator mobile app provides a useful add-on for ultrasound education and training. Our results indicate that medical students’ use of the mobile app for training purposes improved the quality of kidney measurements.
