Rationale: Geriatric patients show a high prevalence of chronic diseases and a high number of risk factors for malnutrition which both can be influenced by nutritional support. This project aimed to describe the nutritional support in geriatric patients, and the changes for hospital personnel after establishment of a nutrition support team. Methods: We retrospectively assessed the characteristics, nutritional status, and nutritional therapy of 1252 patients (57.2% of all geriatric patients) attended by a nutrition support team in 2010 at a geriatric ward. Additionally, the changes through the establishment of a nutrition support team have been analysed. Results: Patients were impaired in the activities of daily living, mobility, and cognition. A total of 17.7% were well nourished, 58.7% showed a risk for malnutrition, and 23.6% were malnourished. The mean BMI was at 25.3±5.6 kg/m2 (MD 24.5, MIN 14.0, MAX 54.5). A low calcidiol level has been found in 97.4% of the patients, a low folate level in 60.5%. The most frequent reason for nutrition counselling was malnutrition and the risk for malnutrition. After establishment of the nutrition support team, number of diagnoses related to nutrition, and supplementation of at-risk nutrients increased. In 96.3% of the patients a malnutrition risk-screening has been executed, and in 93.8% of the patients the weight at hospital admission and discharge has been documented. Conclusion: The high percentage of patients attended by the nutrition support team underpins previous results emphasising the need for nutritional support for geriatric patients. It could be shown that the establishment of a nutrition support team is associated with a number of changes and improvements in patient care which are not only important for nutritional support, but also for medical treatment.
