Systematic review of nutritional status evaluation and screening tools in the elderly.
One univocal definition for nutritional status (NS) does not exist. One set of generally accepted standards for assessing the nutritional status does not exist, either. The NS assessment is absolutely necessary because it drives to identify malnutrition which is a potential cause and or an aggravation of morbidity and mortality. Since malnutrition shows a high prevalence in the elderly, literature about the validation of tools exploring single or complex NS parameters in the elderly has been systematically review. 115 papers, published from January 1st 1990 to July 31st 2003, have been identified: among them, just 9 complied with the established quality criteria and were suitable to be systematically reviewed. Parameters and diagnosis protocols to assess NS used in the selected papers were not homogeneous. Two implications arise from this evidence: - as regards clinical practice: an assessment on NS in clinical practice is complex, but not impossible. Hopefully, despite the absence of a sure reference, nutritionists, during their own clinical practice, ought to choose a validated on their own population and complete tool (considering as NS indicators both dietetic, anthropometric and functional parameters) for NS assessment, among all the redundant set of tools proposed until now; - respecting a scientific point of view, there is the necessity for calling a consensus conference in order to establish an initial consensus to diagnose malnutrition in the elderly and to promote, therefore, a validation study.
