Main hierarchies
Terminology for nutrition interventions are represented in the SNOMED CT 386373004 | Nutrition therapy (regime/therapy)| hierarchy to facilitate recording nutrition interventions such as food and/or nutrient delivery, or coordination of nutrition care by a nutrition professional. Counselling interventions are represented in SNOMED in the 441041000124100 |Counseling about nutrition (regime/therapy)| hierarchy
Key branches:
386373004 | Nutrition therapy (regime/therapy) |
384760004 |Feeding and dietary regime (regime/therapy)|
61310001 |Nutrition education (procedure)|.
Key attributes and value ranges
A range of attributes are available to represent the properties for concepts in this hierarchy (); however, the key attributes that are used for content in the scope of nutrition assessment and reassessment include:
Method: This attribute links to a concept from the Action (qualifier value) hierarchy and specifies the action used to perform the procedure, e.g. education, counselling, administration.
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. Currently, there is one template outlining the model for a modified substance diet . However, additional templates may be developed in the future to support various interventions.
This template ensures that nutrition diagnosis concepts are modeled in a clear, consistent, and clinically relevant manner, supporting effective documentation and interoperability in healthcare settings.
Has focus: This attribute links to a concept from the clinical finding or procedure hierarchies, specifying the particular clinical finding or procedure that is the primary focus of the current procedure, e.g. For 437331000124101 |Increased iron diet (regime/therapy)| the focus is an inadequate intake of iron (finding)
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 (); 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.
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.
This template ensures that nutrition assessment concepts are modeled clearly, consistently, and clinically relevant, supporting effective documentation and interoperability in healthcare settings.
Please view the examples below illustrating the modeling of these concepts.
To facilitate the development of nutrition-related content in SNOMED CT, the NCPT Clinical Project Group was established, bringing together nutrition and dietetics professionals across several continents. This group played a pivotal role in reviewing, validating, and authoring content directly into the SNOMED CT International Release with support from SNOMED International authors. The work of the project group, which took place between 2017 and 2023, concluded with the integration of NCPT (Nutrition Care Process Terminology, Edition 2020) into SNOMED CT.
The responsibility for maintaining nutrition and dietetics content within SNOMED CT has since, transitioned to the Nutrition and Dietetics Clinical Resource Group (CRG). This group is now tasked with overseeing the management of nutrition-related concepts, maintaining the SNOMED CT NCPT reference set, and leading quality improvement projects in collaboration with SNOMED International. The Academy of Nutrition and Dietetics continues to provide stewardship through dedicating staff support.
When clinical concepts are modeled using a set of rules (these rules are explained in the SNOMED CT Editorial Guide), this allows for consistent representation of clinical information in electronic health records (EHRs). Thus, good modeling enhances the quality of the data. Also, modeling of concepts offers the necessary infrastructure to carry out data analytics, collapse, or parse different sets of data. This means that data can be analyzed with different levels of granularity, across different settings, and reused by many for different objectives. (for more information on data analysis with SNOMED CT, please refer to: Data Analytics with SNOMED CT and Data Analytics Tooling)
High-quality modeling of clinical concepts is crucial for ensuring data quality and maximizing the utility of health information. Effective modeling supports the automation of processes and the generation of knowledge at various levels, from individual healthcare services to institutional, regional, national, and international systems.
Population Analytics : With SNOMED CT, healthcare organizations can analyze population data to identify patterns and trends across patient groups. This enables the detection of shifts in the prevalence of clinical issues (such as nutrition-related problems), procedures, and interventions over time, helping to inform public health initiatives, resource allocation, and policy development.
Clinical Decision Support Systems : SNOMED CT serves as a foundation for clinical decision support, enabling systems to provide timely, evidence-based recommendations. By standardizing data, it also facilitates accurate laboratory reporting and registry tracking and reporting, improving the precision and consistency of clinical decision-making and documentation.
Removing Language Barriers : SNOMED CT supports multilingual use, allowing healthcare data to be shared and understood across language divides. This is especially valuable in diverse or multilingual regions, as it enables healthcare providers to communicate consistently and accurately regardless of language.
By modeling clinical concepts with precision, SNOMED CT not only enhances data quality but also empowers healthcare systems to harness data for deeper insights, improved decision-making, and more equitable, coordinated care globally.
This chapter provides a comprehensive overview of SNOMED CT content specific to the Nutrition Care Process Terminology (NCPT). The objective of the following sections is to explain how SNOMED CT concepts relevant to the Nutrition Care Process (NCP) are modeled within the SNOMED CT framework.
It is important to note that there is no single, unified hierarchy dedicated solely to “nutrition content” within SNOMED CT. Instead, relevant content is distributed across various sub-hierarchies according to broader domains, such as Procedures , Clinical Findings , and others. This division ensures that nutrition-related concepts are aligned with the overarching structure of SNOMED CT while remaining accessible within the appropriate contexts.
To aid understanding and interpretation, each page of this chapter will introduce relevant content, along with explanations of its modeling approach, attributes, and examples. This layout is designed to help readers navigate and utilize SNOMED CT content for NCPT effectively, with practical examples that demonstrate the structure and utility of each concept within clinical documentation and workflows.
Main hierarchies
Terminology for nutrition diagnosis is predominantly but not exclusively from the Clini cal Finding hierarchy within SNOMED CT. This hierarchy includes concepts related to nutrition-related health issues, conditions, and diagnoses, such as malnutrition, nutrient deficiencies and imbalances.
Key Attributes and Value Ranges
A range of attributes is available to represent the properties for concepts within this hierarchy (); 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 ,
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.
This template ensures that nutrition diagnosis concepts are modeled in a clear, consistent, and clinically relevant manner, supporting effective documentation and interoperability in healthcare settings.
Problems related to intake of energy, nutrients, fluids, bioactive constituents through oral diet or nutrition support.
870404000 |Excessive intake of carbohydrate (finding)|
897491008 |Inadequate intake of protein and/or protein derivative (finding)|
Nutritional findings/problems identified that relate to medical or physical conditions
288939007 |Difficulty swallowing (finding)|
448765001 |Unintentional weight loss (finding)|
Nutritional findings/problems that relate to knowledge, attitudes, beliefs, physical environment, access to food or food safety
1149231004 |Absence of readiness for nutrition behavior change (situation)|
1163267006 |Able to access potable water with difficulty (finding)|
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.
Main hierarchies
Terminology for Nutrition Monitoring and Evaluation is predominantly but not exclusively from the Observable Entity hierarchy, but also from the Clinical Finding hierarchy, which encompass questions, outcomes, and indicators relevant to evaluating nutrition interventions and goals.
The content is modeled in alignment with these previously described hierarchies
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. The templates described in the assessment and reassessment section are also applicable to monitoring and evaluation.
This will also include concepts from Nutrition Assessment and Reassessment section with some additional examples given here. With the exception of historical assessment content, Nutrition Assessment and Reassessment concepts are modified to achieve nutrition care goals and track nutrition care progress in the Nutrition Monitoring and Evaluation step of the NCP.
