Palliative care (from Latin palliare, to cloak) is any form of medical care or treatment that concentrates on reducing the severity of disease symptoms, rather than striving to halt, delay, or reverse progression of the disease itself or provide a cure. The goal is to prevent and relieve suffering and to improve quality of life for people facing serious, complex illness. Non-hospice palliative care is not dependent on prognosis and is offered in conjunction with curative and all other appropriate forms of medical treatment. It should not be confused with hospice care which delivers palliative care to those at the end of life. In the UK, this distinction is not operative; hospices and non-hospice-based palliative care teams both provide care to those with life limiting illness at any stage of their disease.

Concept

The term "palliative care" may be used generally to refer to any care that alleviates symptoms, whether or not there is hope of a cure by other means; thus, a recent [[WHO statement calls palliative care "an approach that improves the quality of life of patients and their families facing the problems associated with life-threatening illness." Palliative treatments may also be used to alleviate the side effects of curative treatments, such as relieving the nausea associated with chemotherapy.

The term "palliative care" is increasingly used with regard to diseases other than cancer such as chronic, progressive pulmonary disorders, renal disease, chronic heart failure, and progressive neurological conditions. In addition, the rapidly growing field of pediatric palliative care has clearly shown the need for services geared specifically for children with serious illness.

Although the concept of palliative care is not new, most physicians have traditionally concentrated on trying to cure patients. Treatments for the alleviation of symptoms were viewed as hazardous and seen as inviting addiction and other unwanted side effects.

The focus on a patient's quality of life has increased greatly during the past twenty years. In the United States today, 55% of hospitals with more than 100 beds offer a palliative-care program, and nearly one-fifth of community hospitals have palliative-care programs. A relatively recent development is the concept of a dedicated health care team that is entirely geared toward palliative treatment: a palliative-care team.

Clarification

There is often confusion between the terms hospice and palliative care. In the United States, hospice services and palliative care programs share similar goals of providing symptom relief and pain management. The most important distinction between hospice and palliative care programs in the United States, however, is that hospice is a Medicare Part A benefit, thus requiring many aspects of hospice care such as enrollment to be regulated by the United States federal government. Non-hospice palliative care, however, is appropriate for anyone with a serious, complex illness, whether they are expected to recover fully, to live with chronic illness for an extended time, or to experience disease progression.
