When a patient needs parenteral or enteral nutrition, be it in a transitory way or as a permanent form, and hospitalization is not strictly required, this treatment should take place in the home of the patient whenever possible. The support with artificial nutrition can be equally efficient, improving the life expectancy ad the quality of life of patients who would otherwise be faced with a much prolonged hospital stay. The Ambulatory and Home Artificial Nutrition group (NADYA) is a multidisciplinary team of health care professionals, from different areas of the national territory, who are dedicated to Clinical Nutrition. With the objective of promoting health and well-being of patients undergoing treatment, and to ease the therapeutic activity of the implicated professionals, this group has developed a series of suggestions for the practice of enteral or parenteral nutrition in the home of the patient. These suggestions include specifications about the technical team, criteria for selection and training of the patients, routes of access, formulas and material needed, follow up characteristics, and associated complications, and the represent a consensus of the regulations necessary for the guarantee of an adequate level of security and efficiency of the at home care of patients who require artificial nutrition support.
