Professionalism in medicine encompasses a set of values including competence, integrity, compassion, respect and dedication to service. It emerged as a concept in the 1990s in response to the growing business model of healthcare and need to reinforce ethical principles. Professionalism is important for medical students to understand as it forms the basis of the patient-physician relationship and trust. While professional values have long existed, it is important for students to dedicate themselves to living according to these ideals from the beginning of their training through compassionate care for patients.
