Malnutrition affects at least three million people in the UK, with 93% of these living in the community (BAPEN, 2018). Conversely, managing malnutrition can result in improvements in patients’ physical function, such as strength, quality of life and clinical outcomes, and reductions in healthcare use (such as hospital stays and admissions) (Stratton et al, 2018). Identifying and managing malnutrition can therefore improve lives and save money (Stratton et al, 2018).
