Ethical dilemmas in providing nutrition.

The decisions involved in the institution of artificial feeding in patients with chronic and/or terminal illness are difficult. They are more complex when one is deciding if nutrition and hydration are to be withdrawn. In both instances the decision must be based on a combination of factors: the patient's right to self-determination; documented medical evidence demonstrating the need for artificial feeding, combined with a risk/benefit analysis if alternative alimentation is recommended; and an appreciation of prior legal decisions as they relate to the implementation of alternative forms of nutrients to sustain life.
