Comparing the adequacy of the MNA-SF, NRS-2002 and MUST nutritional tools in assessing malnutrition in hip fracture operated elderly patients.

Summary Background & aims Malnutrition is common in hip fracture elderly patients. There is no gold standard for screening nutritional risk. We compared the adequacy of 3 screening tools, their association to nutritional measurements and their ability to predict outcome. Methods The Mini Nutrition Assessment Short Form (MNA-SF), the Malnutrition Universal Screening Tool (MUST) and the Nutrition Risk Screening 2002 (NRS-2002) were prospectively determined. Length of stay (LOS), complications, 6 months readmission and up-to 36 months mortality were recorded. Results 215 operated patients were included: 154 (71.6%) were women; mean age was 83.5 ± 6.09 years (66–104). According to the MNA-SF, 95 patients were well-nourished, 95 were at risk of malnutrition and 25 were malnourished. Based on the MUST, 171 patients were at a low risk of malnutrition, 31 at a medium risk, 13 at a high risk. According to the NRS-2002, 134 patients were at a low risk of malnutrition, 70 at a medium risk, 11 at a high risk. A significant relationship between the nutritional groups of the 3 scores (p  Conclusions All screening tools were adequate in assessing malnutrition parameters in hip fracture operated elderly patients, however, only the MNA-SF could also predict readmissions and mortality.
