NRS-2002 Nutritional Risk Screening

Also known as: NRS-2002, Nutrition risk screening

OriginatorJens Kondrup, et al.Year2003Sources2Related methods4

The Nutritional Risk Screening 2002 (NRS-2002), developed by Kondrup et al. and endorsed by ESPEN (European Society for Parenteral and Enteral Nutrition), is a 7-point tool for identifying hospitalized patients at nutritional risk. It combines assessment of recent weight loss, dietary intake, disease severity, and age to stratify the need for nutritional intervention.

Key highlights

  • Validated across diverse hospitalized populations (medical, surgical, critically ill)
  • Combines anthropometric, dietary, and clinical factors into a simple composite score
  • Low cost and time (< 5 minutes) enable universal screening at admission
  • Strong prognostic association: NRS-2002 ≥ 3 predicts complications and poor outcomes
  • Endorsed by major European and international nutrition guidelines

When to use it

NRS-2002 is used upon hospital admission in all hospitalized patients to identify those needing nutritional support. It is recommended by ESPEN guidelines and is standard in many European hospitals. NRS-2002 is less applicable to outpatient or community settings but can be used to flag patients needing referral to dietetics services. Re-assessment is recommended during prolonged hospitalization.

Strengths & limitations

Strengths
  • Validated across diverse hospitalized populations (medical, surgical, critically ill)
  • Combines anthropometric, dietary, and clinical factors into a simple composite score
  • Low cost and time (< 5 minutes) enable universal screening at admission
  • Strong prognostic association: NRS-2002 ≥ 3 predicts complications and poor outcomes
  • Endorsed by major European and international nutrition guidelines
Limitations
  • Does not capture micronutrient deficiencies or specific nutrient needs (protein, amino acids)
  • Subjective assessment of dietary intake; patients may underreport or overreport intake
  • Does not account for swallowing difficulties, food allergies, or cultural dietary preferences
  • Weight loss history depends on patient recall, which can be inaccurate
  • May overestimate risk in obese patients with recent weight loss (overweight patients can be malnourished)

Frequently asked

My NRS-2002 is low; do I need nutrition support?

NRS-2002 < 3 generally indicates low nutritional risk. However, specific conditions (swallowing difficulty, extensive surgery, burn injury) may warrant support regardless of score. Discuss with your dietitian or physician if you have concerns.

Can NRS-2002 predict my recovery?

NRS-2002 is associated with risk of complications and poor outcomes. High risk (NRS-2002 ≥ 3) indicates need for support to optimize recovery. However, individual outcomes depend on disease severity, comorbidities, and treatment response.

What's the difference between NRS-2002 and MUST?

NRS-2002 (European standard) and MUST (Malnutrition Universal Screening Tool, UK standard) are both validated screening tools. NRS-2002 emphasizes disease severity and age; MUST emphasizes unintentional weight loss and BMI. Both are valid; choice depends on setting and guideline preference.

How often should NRS-2002 be repeated?

Initial screening occurs at admission. Re-screening is recommended weekly during hospitalization or if significant clinical changes occur (new GI symptoms, major surgery, increased respiratory support).
