Palliative care psychiatry is an emerging subspecialty field at the intersection of Palliative Medicine and Psychiatry. The discipline brings expertise in understanding the psychosocial dimensions of human experience to the care of dying patients and support of their families. The goals of this review are (1) to briefly define palliative care and summarize the evidence for its benefits, (2) to describe the roles for psychiatry within palliative care, (3) to review recent advances in the research and practice of palliative care psychiatry, and (4) to delineate some steps ahead as this sub-field continues to develop, in terms of research, education, and systems-based practice.
