Palliative care is an interdisciplinary approach to specialized medical and nursing care for people with life-limiting illnesses. It focuses on providing relief from the symptoms, pain, physical stress, and mental stress at any stage of illness. The goal is to improve quality of life for both the person and their family. Evidence as of 2016 supports palliative care's efficacy in the improvement of a patient's quality of life. Palliative care is provided by a team of physicians, nurses, physiotherapists, occupational therapists, speech-language pathologists and other health professionals who work together with the primary care physician and referred specialists and other hospital or hospice staff to provide additional support. It is appropriate at any age and at any stage in a serious illness and can be provided as the main goal of care or along with curative treatment. Although it is an important part of end-of-life care, it is not limited to that stage. Palliative care can be provided across multiple settings including in hospitals, at home, as part of community palliative care programs, and in skilled nursing facilities. Interdisciplinary palliative care teams work with people and their families to clarify goals of care and provide symptom management, psycho-social, and spiritual support.
