Choose Indicators and Interpret Change

An indicator must support a decision

A monitoring indicator is an observable or measurable marker used to judge change after a nutrition intervention. The best indicator is not automatically the most sophisticated laboratory value. It must be valid for the construct, responsive within the review interval, reliable enough to distinguish signal from noise, feasible to obtain, relevant to the patient, and close enough to the intervention mechanism to guide action. Begin with the nutrition diagnosis and ask what would change first if the intervention worked. For inadequate energy intake, actual intake and delivery usually respond before weight, function, wound healing, or length of stay. For a knowledge deficit, accurate teach-back may respond before a disease outcome. Pair an early process or behavior marker with a later clinical or patient-centered marker when the stakes justify it. Avoid a dashboard of unrelated values. Every indicator should answer a stated question and have a planned interpretation.
