The Nutritional Risk Index (NRI) is a nutrition-related risk score used to stratify risk of complications and adverse outcomes associated with undernutrition. It is applied in hospitalized and chronic-disease settings, including older populations.
Formula: NRI is a composite nutrition-risk index where lower totals indicate higher risk.

NRI has longstanding validation in hospitalized and chronic-care populations for nutrition-related risk prediction.
Lower NRI scores indicate greater nutrition-related risk and support intensified nutrition care planning.
Use for nutrition-risk stratification when clinicians need a standardized prognostic nutrition index.
Biomarker and weight-related components can be influenced by fluid status and non-nutritional illness factors.
For related assessments, see GNRI, CONUT and MUST Score.
