Malnutrition among hospitalized patients increases length of stay (LOS) and carries extra hospitalization costs.
To review the impact of malnutrition on hospital LOS and costs in Europe.
PubMed and Google Scholar search. All articles from January 2004 until November 2014 were identified. Reference lists of relevant articles were also manually searched.
Ten studies on LOS and nine studies on costs were reviewed. The methods used to assess malnutrition and to calculate costs differed considerably between studies. Malnutrition led to an increased LOS ranging from 2.4 to 7.2 days. Among hospitalized patients, malnutrition led to an additional individual cost ranging between 1640 € and 5829 €. At the national level, the costs of malnutrition ranged between 32.8 million € and 1.2 billion €. Expressed as percentage of national health expenditures, the values ranged between 2.1% and 10%.
In Europe, malnutrition leads to an increase in LOS and in hospital costs, both at the individual and the national level. Standardization of methods and results reported is needed to adequately compare results between countries.
住院患者的营养不良会延长住院时间（LOS）并产生额外的住院费用。
综述欧洲营养不良对住院时间和费用的影响。
检索PubMed和谷歌学术。确定了2004年1月至2014年11月期间的所有文章。还手动检索了相关文章的参考文献列表。
综述了10项关于住院时间的研究和9项关于费用的研究。各研究中评估营养不良和计算费用的方法差异很大。营养不良导致住院时间延长2.4至7.2天。在住院患者中，营养不良导致个人额外费用在1640欧元至5829欧元之间。在国家层面，营养不良的费用在3280万欧元至12亿欧元之间。以国家卫生支出的百分比表示，这些值在2.1%至10%之间。
在欧洲，营养不良在个人和国家层面都会导致住院时间和住院费用增加。需要对报告的方法和结果进行标准化，以便在各国之间充分比较结果。
