History and Perspectives on Nutrition and Hydration at the End of Life.

The question of whether to provide artificial nutrition and hydration (ANH) to a patient with terminal illness or at end of life has been debated over many years. Due to the nature of the question and the setting in which it presents, prospective trials are not feasible, and the health care professional is left to work with the patient and family to make decisions. This perspectives piece addresses the issue in a format designed to inform the reader as to the pertinent considerations around ANH. We briefly review significant historic, religious, ethical, and legal contributions to this discussion and physiologic underpinnings. We address the beliefs of patient, family, and health care providers surrounding this issue. Our goal is to provide a review of the considerations for health care providers as they address this issue with patients and families in the course of compassionate care.
