By means of a simplified questionnaire, the NADYA group has gathered and analyzed data with regard to the age, sex, diagnosis, access route, duration, form of administration, complications, and quality of life, in 812 patients (62% male; 37% female) with At Home Enteral Nutrition (AHEN), and 19 patients (42% male; 57% female) with At Home Parenteral Nutrition (AHPN) corresponding the National Registry of 1995. The most frequent indication of AHEN was a neoplasm (41%), followed by neurological alterations (33%). The most common access route is the NGT (37%) followed by oral administration in 37%, PEG in 13% and surgical ostomics in 8%. The mean treatment time is 8 months. The index of complications/patient-year is 0.50 (gasterointestinal 0.17, and mechanical alterations 0.9). At the end of the study, 63% of the patients continued to receive AHEN, showing a mortality rate of 70%. The majority of the patients undergoing treatment presented a sever social disability (20%) or were bed ridden (18%). The most common indications for the AHPN are: radical enteritis (26%), Crohn's disease (21%), and mesenteric ischemia (16%). AIDS, motility alterations, and neoplasic diseases are scantly represented (10%). Tunneled catheters are used in 58% of the cases, and Port-a-Cath in 31%). The mean duration for the treatment was 7.9 months. An index of 0.47 hospitalization/patient-year was seen in relation to the nutritional treatment (mainly due to catheter septicemia). A mortality of 16% is noted, and 21% show a recovery of the oral route. 42% of the patients did not present an assessable social disability.
