# 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](https://app.gitbook.com/s/uoSxuN6wQMDYcvuq2wNX/readme/authoring/domain-specific-modeling/observable-entity/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*](https://conf.spaces.snomed.org/wiki/spaces/SCTEMPLATES/pages/134001915/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.
