What do the PINI, NRI, and PNI have in common?

• A. They are dietary assessment tools
• B. They are laboratory tests for vitamin levels
• C. They are prognostic indices that include objective measures of nutrition status
• D. They measure inflammatory markers only

Answer: (C)

These indices are prognostic tools that combine objective nutrition-related measurements to assign a risk score and predict outcomes. They use concrete data such as serum albumin, lymphocyte counts, and weight loss, sometimes along with other objective markers, to reflect a patient’s nutritional and inflammatory status. They aren’t dietary screening tools, nor are they solely laboratory tests for vitamins or just inflammatory markers; their purpose is to provide a prognostic index based on objective nutrition-related data. That combination of measurable nutrition status data and the ability to predict outcomes is why they are categorized as prognostic indices that include objective measures of nutrition status.
