To truly tackle the issue of malnutrition in the nursing home setting, a consistent definition is needed. We strongly recommend that an expert consensus panel identify a standard set of measures to more accurately compare the prevalence across countries. Given the mortality consequences of malnutrition and the paucity of intervention studies, research on interventions for malnutrition in the nursing home needs to be a higher priority for facilities, researchers, and funding agencies.

The results across studies were inconsistent, justifying the need for further research.
