The article describes the development, implementation, and evaluation of a capstone simulation course for medical school graduates in the Middle East, focused on the transition to residency. The course was created according to the modified seven-step Kern model and included simulation methods, Kolb's model of experiential learning and e-learning. Major course topics included patient safety, basic and advanced procedural skills, night shift, acute management and CPR training. The course was linked to key competencies according to Entrustable Professional Activities (EPAs). The evaluation showed significant improvement in students' psychomotor skills with statistically significant results (p < 0.001, Cohen's d = 1.02 to 2.29) and high participant satisfaction. The organization of the course included centralized communication, independent evaluators and digitization of processes, which helped to overcome organizational challenges. The study emphasizes the importance of a systematic approach to implementation, sustainability and recommends the development of specific training for residents. The course thus effectively helps to bridge the gaps in medical education before the start of clinical practice[1][2].
