The sub-specialty medical clerkship is a 10-week rotation offered at our affiliated teaching hospitals. Learning will be primarily patient-oriented. Students devote 80% of their time evaluating medical patients in the allocated hospitals at both inpatient and outpatient clinical settings, with the remaining 20% assigned for didactic teaching and seminars. The course expands knowledge, skills, and competencies in the following subspecialties; Cardiology, Pulmonary and Critical care Medicine, and Hematology and oncology. Faculty instructions and supervision are commenced on daily basis by bedside tutoring and case-based discussions. A clinical skill component runs on weekly basis in the Clinical Simulation Center to complement the bedside teaching.
