Effectiveness and Cost-Effectiveness Study of Medical Nutrition in Malnourished Patients in Spain

COSNUT pretends to assess the cost‐effectiveness and cost‐utility of oral nutritional supplementation (ONS) in persons with malnutrition and other clinical conditions. The effectiveness will be evaluated by comparing the intervention group having ONS vs a control group only with nutrition advice. The effectiveness and resource use will be collected using quality of life assessment tools, body mass index, change in malnutrition state, number of hospital admissions, medical visits... Unitary costs for Spain will be extracted from databases and official publications and will be applied to the number of resources used in order to calculate the costs in each of the groups. Finally, the incremental cost‐effectiveness ratio will be estimated and presented.
