Comparison of the clinical value among different nutritional evaluation methods for super aging patients with high risk of pressure ulcers

Abstract

Objective To explore the pressure ulcer incidence and nutrition evaluation of 102 hospitalized super aging patients (80-90 year-old) by the subjective comprehensive nutrition evaluation method (SGA), the micro-nutrition evaluation method (MNA-SF), and nutritional risk screening 2002 (NRS 2002). Methods A total of 102 hospitalized super aging patients had been selected by the convenient sampling method and documented the incidence pressure ulcer according to three methods of nutritional screening from August 2012 to December 2014. We combined with the traditional measurement methods and laboratory index to compare the correlation between them, and combined with the ROC to evaluate the sensitivity and specificity of different pressure ulcers. The evaluation of the advantages and disadvantages were also discussed. Results In elderly patients, the incidence of pressure ulcers was 35.29%, the detection rate of MNA-SF, NRS 2002, SGA evaluation methods in malnutrition were 74.5%, 54.9% and 29.4%. The MNA-SF detection rate of malnutrition was higher than the other two methods. All three nutrition detection methods had negative correlation with traditional nutrition measurement and indexes results of laboratory (P 0.05). While we assessed the sensitivity of pressure ulcer, the MNA-SF was 86.1%, NRS 2002 61.0%, SGA 33.3%, and the three specificity were 68.2%, 51.5%, 27.3%. Conclusions MNA-SF has a better effect than SGA and NRS 2002 at detection of malnutrition and the effect of pressure ulcer.
