Analyses of Malnutrition Screening in Internal Medicine

The goal of this observational study is to study the presence and consequences of malnutrition risk in hospitalized internal medicine patients. The main questions it aims to answer are: 1. How many patients are at risk of malnutrition at admission? 2. Is there a link between an existing malnutrition risk and nutrition therapy that the patients receive? 3. Is there a link between an existing malnutrition risk and clinical outcome (e.g. length of hospital stay, mortality, need for rehospitalization)? Participants will be screened for malnutrition risk at admission using a validated questionnaire (Nutritional Risk Screening 2002). All relevant data regarding hospital stay will be obtained from the clinical information system after discharge.
