There is a clear rationale for elucidating effective ways of identifying and treating disease-related malnutrition (DRM), given the physiological and financial consequences of this common condition and its treatability. Evidence indicates the efficacy of nutritional support methods (oral, tube and intravenous) in increasing total nutritional intake while having little effect on appetite, satiety, appetite mediators (e.g. leptin) and voluntary food intake. When used as the only source of nutrition, artificial nutrition can effectively maintain nutritional intake, and yet many patients find enteral or parenteral feeding alone is unable to relieve distressing appetite sensations, and unusual temporal patterns (including dissociation between hunger and desire to eat) occur. Despite the positive impact of these feeding methods on intake, controversy about whether nutritional support can affect patient outcome has remained. Systematic reviews and meta-analyses indicate that improvements in function and clinical (mortality, complication rates) outcome can occur in a number of patient groups (including hospitalised patients, the elderly, patients who have had gastrointestinal surgery, patients at risk of pressure ulcers). In order to target those patients who will benefit from nutritional support, and overcome the ongoing problem of poor detection and recognition of DRM, simple routine screening to identify risk followed by practical evidence-based treatment is recommended.
