    Abstract

    Rationale: Analyse the criterion related validity, interrater reliability and the usefulness of MEONF, an instrument for undernutrition risk screening. Methods: 100 patients were included and assessed with Mini Nutritional Assessment (MNA) regarded as golden standard and screened with Malnutrition Universal Screening Tool (MUST) as well as Minimal Eating Observation and Nutrition Form (MEONF). Results: Nurses regarded MEONF instructions and questions easy to understand, easy to answer (100%) and questions as being important (98%). It had acceptable sensitivity (0.83) and specificity (0.78) in relation to MNA. Sensitivity was higher than found between MUST and MNA (0.57). Replacing BMI with Calf Circumference (CC) gave equivalent results (sensibility 0.83, specificity 0.79) in relation to MNA. Interrater reliability was high (kappa 0.81). Conclusions: MEONF has good validity in relation to MNA and high interrater reliability. If replacing BMI with CC the precision is maintained, which is important in cases were weight or height is difficult to obtain. Having high sensitivity is a major concern for nutritional screening instruments and in that respect MEONF works better than MUST. One fundamental gain with MEONF is that the instruments criteria are experienced as clinically meaningful, in that some observed difficulties can be managed by nursing interventions.
