    Abstract:
    INTRODUCTION: The prevalence of malnutrition in patients admitted with a proximal femoral fracture is considered high and the negative effects on health are well-studied. The SNAQ and the MNA-SF are two screening tools routinely used during admission of acute medical patients. The aim of this study is to compare the screening capacity of the SNAQ score and the MNA-SF, and to evaluate their predictive values for malnutrition using the ESPEN criteria. MATERIALS AND METHODS: A single-centre study with data routinely collected prospectively from the original patient records was performed in the Haaglanden Medical Centre Bronovo in the Netherlands. All patients with a proximal femoral fracture consecutively admitted between December 19th 2016 and December 21st 2017 were included. The Intraclass Correlation Coefficient was used to assess the agreement between the malnutrition screening tools and the predictive values were calculated to compare the SNAQ with the MNA-SF using the ESPEN diagnostic criteria as the reference standard. RESULTS: Data was available from 437 patients. Of all patients admitted with a proximal femoral fracture 16.9% was diagnosed as malnourished by the ESPEN criteria. When screened, 20.1% (SNAQ score) to 47.8% (MNA-SF) of all patients were classified as either at risk for malnutrition or as malnourished. A moderate agreement was found between the MNA-SF and the SNAQ (κ = 0.68). The sensitivity, specificity, PPV and NPV of the SNAQ score were 71.6%, 90.4%, 60% and 94% respectively, compared to 100%, 62.8%, 35.4% and 100% for the MNA-SF. DISCUSSION: The SNAQ has been proven to be a very specific screening tool and the positive predictive value tends to be higher than that of the MNA-SF. However, 28.4% of all malnourished patients with a proximal femoral fracture had a negative screening test when using the SNAQ score. CONCLUSIONS: No benefits were observed for the SNAQ over the MNA-SF as a screening tool for malnutrition in admitted patients with a proximal femoral fracture. Missing a significant portion of malnourished patients or those at risk and consequent under treatment of fragile older patients should be avoided. The well-validated MNA-SF seems more preferable as a screening tool for this patient population.
