The aim of this study is to assess the benefit of a 3-month intervention with oral nutritional supplements (ONS) in older ambulant patients with reference to functional limitations and quality of life as well as the consumption of health care resources.

Study participants are assessed upon discharge from the hospital and again after 3 months. Upon discharge all patients receive nutrition counselling with special focus on an energy rich diet. Additionally, the intervention group receives ONS. The investigators hypothesize an improvement in functional limitations and health economic benefits due to the post-hospital nutritional intervention.
