[Study of malnutrition with residents of nursing homes. Interviews of relatives, nursing staff and survey of nursing documentation].

Malnutrition is a common problem in in-patients nursing homes. A body mass index (BMI) that is lowerthan 18.5 kg/m2 is the first indication for malnutrition. In three studies BMI and other data were therefore collected. Family members and nurses of wards for residents suffering from dementia were interviewed and nursing documentation was analysed. Almost every tenth resident has a BMI that is lower than 18.5 kg/m2. The results clarify the need to identify malnutrition in the early stages by screening and assessment as well as the need for a nutrition supply that is focussed on the demands and needs of residents. A standard for in-patients nursing homes has been worked out based on the results of the studies.
