Malnutrition is a significant problem amongst hospitalised older people, and can impede effective recovery. Oral nutritional supplements (ONS) are limited by their poor tolerability and an alternative strategy is food fortification, the addition of protein/energy/micronutrients to frequently eaten food. The aim of this pilot study is to establish the feasibility and acceptability of delivering fortified foods to older people including those who have dementia and frailty whilst in hospital and to assess whether fortified foods could increase the energy and protein intake.
