Consultation-liaison psychiatry is a subspecialty of psychiatry that focuses on the interface between mental health and general medical care. In Europe, consultation-liaison psychiatry has a long history and is an established field of practice. The primary goal of consultation-liaison psychiatry is to provide psychiatric assessment, diagnosis, and treatment to patients with medical or surgical conditions that impact their mental health. Consultation-liaison psychiatrists work collaboratively with medical teams to manage the psychological and emotional aspects of illness and its treatment. In addition to providing direct patient care, consultation-liaison psychiatrists also participate in research, teaching, and advocacy activities related to the interface between medicine and psychiatry.
