Hospice is a large program encompassing a wide range of services and care for those afflicted with a terminal disease and their families. Hospice strives to treat the physical, emotional and spiritual needs of the patient. A nurse makes home visits to help manage symptoms, while home health aides help with personal care and companionship. Social workers aide with emotional support and advanced directives, speaking with families to determine strengths and needs, coordinate problem solving, counselling and referrals. Finally, chaplain services provide spiritual support upon request. Palliative care exists to enhance the comfort and quality of life, with no specific therapy being excluded from consideration.
