In the United States, hospice care is a type and philosophy of end-of-life care which focuses on the palliation of a terminally ill patient's symptoms. These symptoms can be physical, emotional, spiritual or social in nature. The concept of hospice as a place to treat the incurably ill has been evolving since the 11th century. Hospice care was introduced to the United States in the 1970s in response to the work of Cicely Saunders in the United Kingdom. This part of health care has expanded as people face a variety of issues with terminal illness. In the United States, it is distinguished by extensive use of volunteers and a greater emphasis on the patient's psychological needs in coming to terms with dying.
