The registries are databases including information about a treatment or a disease in a definite population. Concerning home artificial nutrition there are registries of patients in different European countries, USA and Japan, collecting data such as the prevalence, indication, follow-up and complications of these treatments. The Spanish group of Home Artificial Nutrition (HAN), NADYA, was established in 1992 with professionals devoted to the practise of artificial nutrition. Since then, one of its wills was the development of the Spanish registry of HAN. This is a voluntary registry accessible through the web page www.nadya-senpe.com. In 2005, this group decided to update the registry according to the Data Protection Law and including other improvements. Thank to the work of all the members of this group we have many data on the practise of HAN in our country. Since 1994, except the years 97-98, the annual registries of patients on home parenteral nutrition and home enteral nutrition have been published periodically, observing an increase in both, the number of patients and collaborating centres, presenting to us the actual practise of HAN in our country.
