Content and Modeling

Main hierarchies
- Terminology for nutrition diagnosis is predominantly from the Clinical Finding hierarchy within SNOMED CT. This hierarchy includes concepts related to nutrition-related health issues, conditions, and diagnoses, such as malnutrition, nutrient deficiencies, and dietary imbalances.
Key Attributes and Value Ranges
- A range of attributes is available to represent the properties for concepts within this hierarchy (Clinical Finding Defining Attributes); however, the key attributes relevant for nutrition assessment and diagnosis include:
  - Interprets: This attribute links the diagnosis to an observable entity being assessed or measured. For example, a diagnosis of 'difficulty swallowing' interprets the observation related to a patient's 'ability to swallow', see the example below. This attribute specifies what aspect of nutrition or health is being interpreted within the context of the diagnosis.
  - Has Interpretation: This attribute represents the outcome or evaluation of the observation, specifying how the observation is interpreted in relation to the diagnosis. For example, it may link to a Qualifier Value such as Deficient, Excessive, or Normal intake, providing a clear description of the interpretation relevant to the nutrition diagnosis.
  - These attributes, Interprets and Has Interpretation, ensure that each diagnosis is directly linked to the observed data and its interpretation, allowing for precise and standardized representation of nutrition-related diagnoses within SNOMED CT.

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. Nutrition intake (finding) - v1.0

These templates ensure that nutrition diagnosis concepts are modeled in a clear, consistent, and clinically relevant manner, supporting effective documentation and interoperability in healthcare settings.
