Nutritional Risk Index (NRI) 1.0

Nutrition status assessment is important in the detection of protein energy malnutrition (PEM), dietary requirements, and the development of the alternative nutritional therapies in patients with chronic diseases. Malnutrition is a strong predictor of mortality and morbidity. There are many tools for the assessment of nutrition status. Nutrition risk index (NRI) specific and positive predictor for identifying patients with risk of malnutrition and validated in many populations.

Nutritional Risk Index (NRI) Calculator app will calculate the Nutrition risk index (NRI) score and classify the Nutritional Risk Index (NRI) score. The patients with Nutritional Risk Index (NRI) score of more than 100 was considered in no risk group, 97.5–100 mild risk, 83.5–97.5 moderate risk, and less than 83.5 has severe risk groups. Although weight and nutritional status are not always correlated (e.g. obese patients may have malnutrition), for the purposes of this calculator, patients with increased weight from baseline (present weight more than usual weight) are unlikely to have malnutrition.
