A MDS study group attends to the much-discussed problem of malnourishment of older people and people in need of care, especially in in-patient geriatric care, with a guideline statement „Nourishment and Liquid Supply of Older People“. It is the final report of the project group P 39 of the MDS (i.e. the medical service of the responsible central organisations in health insurance), July 2003. This guideline statement can surely contribute to a nurse’s stronger problem awareness of malnourishment and risks of nourishment deficits for old people. However, according to the national group for nursing assessment Germany (RAI group), some advices demand a more differential consideration.
