Evaluation of an Online Application for Point of Care Ultrasound Training in General Internal Medicine Residents

This study compares Point of Care Ultrasound (POCUS) training in two hospitals, one that uses an online application for supervision and one that does not use the application. The goal of this trial is to learn if POCUS supervision using the online application is associated with improved POCUS skills in residents in General Internal Medicine (GIM). The main question it aims to answer is: \- Do POCUS skills improve more during 6 months in GIM residents supervised using the application than in GIM residents who do not use the application? Further questions the study aims to answer are: * Do residents using the application perform more POCUS exams during 6 months than residents not using the application? * Are residents using the application more satisfied with their POCUS training than residents not using the application?
