Experience of 6 years with home enteral nutrition in an area of Spain.
OBJECTIVE
The wide spread use of long-term enteral nutrition and the substantive costs dictate a need to study outcome, clinical and epidemiological characteristics of these patients. The aim of our study was to analyze incidence and characteristics of a cohort of patients on HEN during 6 years, after our previous pilot study of 3 years.


METHODS
Prospective observational study.


METHODS
Tertiary care.


METHODS
Between January 1999 and December 2004, all adult patients living in Valladolid West area who were discharged from the hospital on HEN were prospectively studied and followed up.


METHODS
Information for each patient was prospectively recorded by the dietitian of the team, and include age, sex, body mass index, tricipital skinfold, midarm circumference, underlying disease, exitus, dates of initiation and discontinuation of HEN, nutrient formula, mode of administration and complications of HEN. During HEN, physicians supervised the home patients and the patients themselves or their close relative, were asked to contact our nutrition team if any problem occurred. Finally the yearly incidence of HEN was calculated each year on the basis of the estimated population in our area of recruitment, assuming almost all HEN patients were reported.


RESULTS
In our previous study, incidence of HEN in 1999 was patients 15 per 100,000 inhabitants, 21.3 in 2000 and decreased to 9.52 in 2001. In the new 3 years, the incidence remained in the mean levels of 1999 and 2000, the data were 17.1 per 100,000 inhabitants 26.5 in 2003 and 25.6 in 2004. The mean age of all patients was 56.4+/-17 years. The distribution of patients by diseases was; (43.8%) had a head and neck cancer, (26.8%) had human immunodeficiency virus infection, (9.6%) had a neurological disorders affecting swallowing (cerebrovacular accident and/or dementia), (4.7%) had diseases in digestive tract (fistulae, pancreatic disease, inflammatory bowel disease), (2.5%) had tumors in different locations with anorexia, (5%) had head trauma, and (7.6%) had one of several miscellaneous diseases inducing dysphagia or anorexia. HEN was administered via oral in 258 patients (70.6%) (group I), via a NGT in 95 patients (26.1%), a PEG in 9 patients (2.5%), and a jejunostomy in 3 patients (0.8%) (group II=107 patients). During the course of HEN, 12 patients had diarrhea (3.3%) and 8 (2.2%) constipation, and 4 vomiting (1.1%) that did not require cessation of HEN. No lung aspiration was detected. Hypernatremia (sodium >145 meq/l) appeared only in six cases (1.64%) and 12 cases of hyperglycaemia (3.28%). Ten patients (2.8%) reported a least one problem with the tube. The mean duration of HEN was 148.2+/-104 days. After the follow-up, 19 of the 365 patients (5.2%) had died, 346 (94.8%) were alive. In multivariant analysis, an independent factor associated with death was age (hazard ratio: 1.22; 95% CI: 1.06-1.39), adjusted by sex, route and diagnosis.


CONCLUSIONS
HEN has a high incidence in our area and it is a valid and safe technique for nutrition support.
