[When Digital Meets Diagnostics: E-Learning Effectiveness in Internal Medicine Sonography Training]

Sonography is a key component of internal medicine diagnostics, making the teaching of basic sonographic skills essential. This study aimed to evaluate the effectiveness of an abdominal-sonography-specific e-learning intervention.In this prospective controlled study, medical students were assessed before (T1) and after (T2) completion of the e-learning within a blended-learning framework. At T2, competence levels and evaluation outcomes were additionally compared with a reference group of physicians who had used the same module to prepare for a certified abdominal ultrasound course. Objective theoretical competencies were measured via written tests; subjective competencies and acceptance were assessed using 7-point Likert scales. Demographic data and usage behavior were also collected.A total of 191 participants were included (144 students, 47 physicians). Students showed significant improvements in objective and subjective competence domains (each p < 0.001). Physicians rated their competencies higher, whereas test scores did not differ significantly between groups (p = 0.07) at T2. Both groups rated the e-learning highly (mean >6.0 scalepoints). Completion time and number of completed modules were relevant influencing factors.The demonstrated competence gains and high acceptance highlight the potential of integrating digital learning resources more extensively into ultrasound education.
