Volunteers are integral to palliative care worldwide, including North America, Europe, Africa, and India. Global mortality is predicted to rise by between 14% and 42% from 2002 to 2030 with many deaths following a period of progressive chronic illness increasing demand for palliative care. In many countries palliative care is provided in hospices or hospice programs. In the United States there are nearly half a million hospice volunteers, and more than 100,000 in the United Kingdom (U.K.), where their contribution reduces hospice costs by an estimated 23%.U.K. hospice services are specialist palliative care units which typically provide inpatient and day care (a service provided in a hospice building to nonresidents), as well as home-based care. Patients with advanced progressive disease are eligible for such care. Services are free to patients (although availability varies across the United Kingdom), with referral usually via health care professionals.
