Psychiatric morbidity among terminally ill patients is quite common, with some estimates of delirium approaching 80 percent and depression 50 percent. Recent research efforts repeatedly underscore the central importance of addressing psychiatric and psychosocial issues to optimize care of the terminally ill. These issues include problems such as depression, anxiety, suicidal ideation, delirium, eating disorders, fatigue, grief, loss, and bereavement as well as questions regarding capacity to make decisions and overall quality of life.
