Hip fractures are highly prevalent and are expected to increase due to the ageing population. Malnutrition is often present in these patients and is associated with prolonged convalescence, lower mobility, lower mental function, lower quality of life and higher complication rate. Nutritional intervention starting soon after hospital admission might reduce complication rate and total length-of-stay by improving nutritional and functional status. Research questions are:

1. Does nutritional intervention reduce total length-of-stay?
2. Is nutritional intervention cost-effective?
3. Can nutritional screening contribute to targeting of nutritional intervention, and thereby reduce costs without loss of effectiveness?

Patients randomized to the intervention group will receive oral nutritional supplements (protein and energy enriched) and regular dietetic counselling during hospitalisation and after discharge at patients' homes for 3 months. Patients in the control group will receive usual nurse and dietetic care. Outcome measurements will be taken at baseline, 3 months and 6 months after inclusion.
