Аннотация:Background & AimsDisease related malnutrition (under-nutrition caused by illness) is a worldwide problem in all health care settings with potentially serious consequences on a physical as well as a psycho-social level.In the European Union countries about 20 million patients are affected by disease related malnutrition, costing EU governments up to € 120 billion annually.The aim of this study is to calculate the total additional costs of disease related malnutrition in The Netherlands. MethodsA cost-of-illness analysis was used to calculate the additional total costs of disease related malnutrition in adults for The Netherlands in 2011 in the hospital, nursing-and residential home and home care setting, expressed as an absolute monetary value as well as a percentage of the total Dutch national health expenditure and as a percentage of the total costs of the studied health care sectors in The Netherlands. ResultsThe total extra costs of managing adult patients (>18 years of age) with disease related malnutrition was estimated to be € 1.9 billion in 2011 which equals 2.1% of the total Dutch national health expenditure and 4.9% of the total costs of the healthcare sectors analysed in this study. ConclusionsThe results of this study show that the additional costs of disease related malnutrition in adults in The Netherlands are considerable.
