A critical evaluation of the use of nutrition screening tools by nurses.

Abstract

Malnutrition remains a problem in hospital and community patients, the consequences of which have deleterious effects on the sick individual and cost implications for healthcare providers. Provision of nutritional support has been shown to improve patient outcome in those at risk of malnutrition; therefore, the detection and treatment of malnutrition is paramount. Nurses have been identified as being in an ideal position to carry out routine nutritional screening to detect patients at risk of malnutrition and hence refer to the dietitian for detailed nutritional assessment and provision of nutritional support. Therefore, many nutritional screening tools have been developed to guide nurses in basic nutritional screening. However, for a tool to be effective certain criteria must be met including ease of use, cost-effectiveness, the presence of an action plan and prior testing for validity, reliability, sensitivity and specificity. Six such tools are critically evaluated in this article to establish whether they meet these criteria. Surprisingly, none of the screening tools demonstrated a beneficial effect on clinical outcome or met all of the above criteria. It is therefore essential that these tools are refined and retested before becoming part of established nursing practice.
