[Prognostic morbidity and mortality factors in hospital enteral nutrition: prospective study].

OBJECTIVE
To determine the prognostic factors that may best for see the outcome of an enteral nutritional intervention and to assess the assistance quality of a nutrition unit.


SETTING AND SUBJECTS
Patients that required enteral nutrition during hospital admission at a third level center.


INTERVENTIONS
Observational prospective study in which 160 patients were included by means of consecutive sampling, for a 6-months follow-up period. Underlying pathology, disability degree, nutritional assessment, type of enteral nutrition, complications, nursing care, and clinical course of patients were determined.


RESULTS
severe caloric and protein hyponutrition was diagnosed in 48.4 and 52.9% of patients; stress degree was moderate in 52.2% and severe in 36.5%. In 88.2% of patients variation of protein parameters was unchanged or improved, with a 0.26 g/dL increase in albumin levels and 2.4 m/dL in prealbumin (p < 0.05). Multivariate analysis adjusted for plasma albumin at admission showed that besides this biochemical parameter, a severe stress degree, a decreased alertness level, and worsening of protein variation during admission are independent prognostic mortality factors during an enteral nutritional intervention in the hospitalized patient (p < 0.05).


CONCLUSIONS
alertness level, degree of caloric hyponutrition, stress degree, plasma albumin levels, and variation of protein parameters during nutritional support are independent prognostic factors for the nutritional intervention outcomes. The development of global monitoring systems of assistance activity and quality of Nutrition Units is paramount in order to improve the efficiency of enteral nutritional support at the hospital setting, to advance in patients care and promote the development of nutritional therapy.
