Evaluating the Effectiveness of a Micronutrient Assessment Tool for Long-Term Total Parenteral Nutrition Patients *

Abstract

Monitoring parameters for patients receiving long-term home parenteral nutrition (HPN) should include assessment of micronutrient status to avoid deficiencies and potential excesses of any micronutrient. This evaluation examined the effectiveness of a standardized micronutrient assessment tool administered semiannually to long-term HPN consumers, for identifying signs/symptoms of a suspected deficiency or excess. All patients assessed were receiving long-term HPN from a single home-infusion provider. Of the 275 micronutrient assessments evaluated, 30 patients were found to have a suspected deficiency. Laboratory tests were ordered for 13 patients: deficiencies were confirmed in 6 patients, no deficiency was found in 4 patients, and 1 patient was not deficient in the suspected micronutrients but was found deficient in others. The micronutrient assessment tool is effective in determining the suspected presence of micronutrient deficiencies. All long-term HPN patients should receive ongoing monitoring by a home care clinician, including an assessment of micronutrient status, to ensure adequacy of the nutrition support regimen.
