Optimising nutrition in residential aged care: A narrative review

In developed countries the prevalence of protein-energy malnutrition increases with age and multi-morbidities increase nutritional risk in aged care residents in particular. This paper presents a narrative review of the current literature on the identification, prevalence, associated risk factors, consequences, and management of malnutrition in the <i>residential aged care (RAC)</i> setting. We performed searches of English-language publications on <i>Medline, PubMed, Ovid and the Cochrane Library</i> from January 1 1990 to November 25 2015. We found that, on average, half of all residents in aged care are malnourished as a result of factors affecting appetite, dietary intake and nutrient absorption. Malnutrition is associated with a multitude of adverse outcomes, including increased risk of infections, falls, pressure ulcers and hospital admissions, all of which can lead to increased health care costs and poorer quality of life. A number of food and nutrition strategies have demonstrated positive nutritional and clinical outcomes in the <i>RAC</i> setting. These strategies extend beyond simply enhancing the nutritional value of foods and hence necessitate the involvement of a range of committed stakeholders. Implementing a nutritional protocol in <i>RAC</i> facilities that comprises routine nutrition screening, assessment, appropriate nutrition intervention, including attention to food service systems, and monitoring by a multidisciplinary team can help prevent decline in residents’ nutritional status. Food and nutritional issues should be identified early and managed on admission and regularly in the <i>RAC</i> setting
