Nutrition Monitoring and Evaluation
Closing the loop
Monitoring is the ongoing, planned collection of indicators; evaluation is the judgment you make when you compare those data with predetermined criteria and goals. Questions routinely blur the two.
Indicators are selected at the time of intervention and tied directly to the nutrition diagnosis. If the PES says intake is inadequate because of nausea, the indicators are energy and protein intake as a percentage of goal, nausea severity, and weight trend - not unrelated laboratory values. Specify the indicator, the criterion or target, and the time frame in advance so the evaluation is not hindsight.
Evaluation outcomes are documented as goal met, partially met, or not met; the plan is then continued, revised, or discontinued. Rewrite the nutrition diagnosis when the problem changes. Discharge from nutrition care happens when goals are achieved and the client can self-manage, not merely when the patient is "stable."
Traps: re-reporting assessment data as if it were monitoring; using an inflammation-confounded marker such as albumin as the primary outcome; omitting whether the goal was met; continuing a plan without evidence that criteria were met.
Worked example: goal set at week 0 - "Mr. K will consume ≥75% of estimated energy needs by week 4." At week 4 a 3-day food record shows 62%. Evaluation: goal partially met. Continue intervention, add an oral nutrition supplement, address early satiety, and revise the criterion to ≥75% by week 6.
