Johansen N et al. Effect of nutritional support on clinical outcome in patients at nutritional risk. Clin Nutr 2004;23:539-550.


Protein and energy intake of patients at nutritional risk (NRS 2002) was increased in the intervention group. Length of stay (LOS) was shorter in the intervention group among patients with complications.

Schwegler et al. Nutritional risk is a clinical predictor of postoperative mortality and morbidity in surgery for colorectal cancer. Br J Surg 2010;97:92-7.


Based on the NRS-2002, there was a significant difference in postoperative complication rate between patients at nutritional risk and those not at risk (62 versus 39.8 per cent; P = 0.004) but not if Reilly's NRS was used (58 versus 44.1 per cent; P = 0.086).
Nutritional risk was identified as an independent predictor of postoperative complications (odds ratio 2.79; P = 0.002).

Raslan et al. Complementarity of Subjective Global Assessment (SGA) and Nutritional Risk Screening 2002 (NRS 2002) for predicting poor clinical outcomes in hospitalized patients. Clin Nutr (e-pub ahead of printing) 2010.


Patients who were both NRS+ and SGA C had higher rates of complicarions than patients who were NRS+ or SGA C only.
The concurrent application of SGA in NRS+ patients might enhance the ability to predict poor clinical outcomes in hospitalized patients.

Raslan et al. Comparison of nutritional risk screening tools for predicting clinical outcomes in hospitalized patients. Nutrition 2010;26:721-6.


Performance in predicting complications, very long length of hospital stay (LOS), and death was analyzed using receiver operating characteristic curves.
NRS 2002 (complications: 0.6531; very long LOS: 0.6508; death: 0.7948) and MNA-SF (complications: 0.6495; very long LOS: 0.6197; death: 0.7583) had largest areas under the ROC curve compared to MUST (complications: 0.6036; very long LOS: 0.6109; death: 0.6363).
For elderly patients, NRS 2002 was not significantly different than MNA-SF (P>0.05) for predicting outcomes.

Ozkalkanli et al. Comparison of tools for nutrition assessment and screening for predicting the development of complications in orthopedic surgery. Nutr Clin Pract 2009;24:274-80.


In patients undergoing orthopedic surgery, NRS 2002 predicted development of complications better than the SGA.

Kyle et al. Comparison of tools for nutritional assessment and screening at hospital admission: a population study. Clin Nutr 2006;25:409-17.


As compared to SGA, the sensitivity was 62%, 61% and 43% and specificity was 93%, 76% and 89% with the NRS-2002, MUST and NRI, respectively.
NRS-2002 had higher positive (85%) and negative predictive values (79%) than the MUST (65% and 76%) or NRI (76% and 66%, respectively).

Guo et al. Screening of the nutritional risk of patients with gastric carcinoma before operation by NRS 2002 and its relationship with postoperative results. J Gastroenterol Hepatol 2010;25:800-3.


Preoperative nutrition score NRS 2002 >= 3 predicted more postoperative complications and longer length of hospital stay.

NRS 2002 and markers of protein malnutrition in geriatric patientsApplications

Drescher et al. Comparison of two malnutrition risk screening methods (MNA and NRS 2002) and their association with markers of protein malnutrition in geriatric hospitalized patients. Eur J Clin Nutr 2010;64:887-93.


Serum prealbumin and retinol-binding protein concentrations were inversely associated with the severity of malnutrition as indicated by the NRS (P=0.06 and <0.01, respectively).
The NRS seems to be superior compared with the MNA and serum proteins in identifying elderly patients at risk of malnutrition during acute intercurrent illness.
