Evidence-based strategies for the use of oral nutritional supplements.

Prescribable oral nutritional supplements are commonly used as a method of nutritional support in the prevention and treatment of malnutrition in adults. There is growing evidence to suggest that when used appropriately in treatment plans, individuals receiving them will benefit from functional and clinical improvements. The use of supplements in the community has increased over the last decade and questions about the increasing costs and efficacy of the products are often raised within health-care communities. The development of guidelines and protocols for the use of supplements in the community that are based on evidence of need and indicate a clear pathway of care, together with intended benefit, should help to address the issues of costly, inappropriate prescribing.
