Nutrition Assessment and Reassessment

Content and Modeling

• Main hierarchies

  • Terminology for nutrition assessment is predominantly from the Observable Entities hierarchy and includes questions relating to client and food/nutrition-related history, anthropometric measurements, biomedical tests and assessment tools. Also included in nutrition assessment is nutrition focused physical findings from the Clinical Finding hierarchy.

• Key attributes and value ranges

  • A range of attributes are available to represent the properties for concepts in this hierarchy (Observable Entity Defining Attributes); however, the key attributes that are used for content in the scope of nutrition assessment and reassessment include:

    • Technique: This attribute links to a concept from the Technique (qualifier value) hierarchy and specifies the observation method, e.g., estimation, measurement.

    • Property: This attribute links to a concept from the Property (qualifier value) hierarchy and specifies the type of feature to be observed, e.g., intake quantity, energy intake.

    • Characterizes: This attribute links to a concept from the Introduction procedure (procedure) hierarchy and specifies the process associated with intake quantity or energy intake, e.g. administration via gastrointestinal route.

    • Please view the examples below illustrating the modeling of these concepts.

• Templates

  • As part of the content development process, authoring templates were created to support future content additions and quality assurance of existing and new content in this area. Nutritional intake (observable entity) - v3.0

This template ensures that nutrition assessment concepts are modeled clearly, consistently, and clinically relevant, supporting effective documentation and interoperability in healthcare settings.
