Palliative care aims to improve the quality of life for those with serious illnesses by treating physical, psychological, and spiritual pain and symptoms. It takes an interdisciplinary, whole person approach involving physicians, nurses, social workers, chaplains and other practitioners. As the population ages and chronic illnesses rise, palliative care can help address the inadequately treated symptoms, fragmented care, and strains on family that many serious illness patients experience. While palliative care programs have expanded in hospitals, continued growth faces barriers in workforce shortages, lack of research funding, and reimbursement challenges.
