In this Pro-Con commentary article, we discuss the models, value propositions, and opportunities of preoperative clinics run by anesthesiologists versus hospitalists and their role in perioperative care. The medical and anesthesia evaluation before surgery has pivoted from the model of "clearance" to the model of risk assessment, preparation, and optimization of medical and psychosocial risk factors. Assessment of these risk factors, optimization, and care coordination in the preoperative period has expanded the roles of anesthesiologists and hospitalists as members of the perioperative care team. There is ongoing debate regarding which model of preoperative assessment provides the most optimal preparation for the patient undergoing surgery. This article hopes to shed light on this debate with the data and perspectives on these care models.
