GOMEZ CANDELA, C.; CANTON BLANCO, A.; LUENGO PEREZ, L. M.  y  OLVEIRA FUSTER, G.. Efficacy, cost-effectiveness, and effects on quality of life of nutritional supplementation. Nutr. Hosp. [online]. 2010, vol.25, n.5, pp.781-792. ISSN 1699-5198.

This article summarizes the main results and conclusions presented in the Symposium "Nutritional supplementation: evidences and experiences" that took place in the XXIII^rd SENPE Congress (2008). Protein energy malnutrition, that can affect 30-50% of hospitalized patients, increases both time of hospitalization and costs of medical care of this kind of patients. There is a lot of scientific evidences demonstrating that the use of nutritional supplementation improves nutritional status or prevents malnutrition in those patients who do not meet their nutritional needs with a conventional diet or an adapted one with no replacing intake from normal food. This is strengthened by the results that demonstrate the rol of nutritional supplements improving nutritional and functional parameters. Current bibliographic reviews focused on certain clinical frameworks (i.g. geriatrics, oncology), prove that nutritional supplements reduce complications related to pathology and to nutritional status, and also reduce length of hospitalization and mortality. More studies regarding to efficacy of oral nutritional supplements are needed. These studies should be carried out with a period of follow-up longer than the current published studies have. As well as effective, nutritional supplements become a save therapeutic intervention with no important adverse events that, according to bibliography, improve patient's functionality and quality of life. It is worth mentioning that nutritional supplements can be effective on certain kind of patients, for instance, malnourished elderly or elderly in risk of malnourishment, and hospitalized surgical patients. Scientific literature refers that it is necessary to carry out more studies, with an accurate methodology, which assess the effect of nutritional supplements on quality of life and its cost-effectiveness on malnourished patients regarding specific clinical situations. That would allow physicians to make clinical decisions based on evidences and cost analysis.
