Nutritional Risk Screening 2002

The NRS-2002 is recommended as a screening tool for the risk of undernutrition in hospitals by the European Society for Clinical Nutrition and Metabolism (ESPEN), the Federal Office of Public Health (OFSP), and the Council of Europe. It is based on the fact that nutritional support is indicated in severely ill patients with increased nutritional needs and/or severely malnourished. 

The score consists of three sections:

Deterioration in nutritional status

– The body mass index (BMI) is calculated with the weight measured the day after the patient's admission and the height estimated by the Chumlea equation using the measurement of the heel-knee distance.

– the decrease in food intake is assessed by questioning and estimated as a percentage.

– Recent weight loss is calculated using the weight measured the day after the patient's admission and a previous weight obtained from the medical file, from the patient or his entourage.

The data indicating the greatest deterioration in nutritional status is used to calculate the score.

Degree of severity of the disease

– The score is calculated according to the references published by Kondrup, taking into account the main diagnosis and the comorbidities of each patient.


– An additional point is added to people ≥ 70 years old.

Patients with a score ≥ 3 should receive nutritional support and an assessment of nutritional status.

Nutritional risk screening

• A process to identify patients who are:

• At the risk of malnutrition (presence of risk factors affecting diet or increasing nutrient or energy requirements)

• Suffering from malnutrition

• Likely to benefit from nutritional assessment and treatment

• A quick and simple process carried out by the staff responsible for admission or working on the front line, generally a nurse rather than a nutrition professional

Why screening is important...

• Malnutrition has negative consequences

• Treatment can improve nutritional status and lead to better outcomes

• Prevalence of malnutrition is high enough to warrant screening

• Malnutrition is under-recognized outside the professional nutrition community
