What is the definition of ‘Terminology’?
A system of terms used in a particular field or subject area
Terminology is essential for clear communication in healthcare.
What are ‘Terminologies’?
Collections of terms and their meanings within a specific domain
They provide a structured way to understand complex information.
Define ‘Concept’ in the context of healthcare terminologies.
An abstract idea or a mental representation of a phenomenon
Concepts are fundamental to the organization of medical knowledge.
What is a ‘Code’?
A symbolic representation of a concept used for identification
Codes facilitate the standardized communication of medical information.
What is the difference between ‘Terminologies and Classifications’?
Terminologies provide definitions while classifications organize terms into categories
Both are essential for data standardization in healthcare.
Define ‘Classification’.
A systematic arrangement of concepts into categories based on shared characteristics
Classifications help in organizing health data for analysis.
What does ‘Ontology’ refer to?
A formal representation of a set of concepts within a domain and the relationships between them
Ontologies are crucial for advanced data interoperability.
What is a ‘Concept identifier’?
A unique code or label assigned to a concept within a terminology
This ensures each concept can be distinctly recognized.
What is ‘Terminology binding’?
The process of linking a data element to a specific value set
This is essential for ensuring accurate data representation.
List the design features for controlled medical vocabularies in the twenty-first century.
- Concept-oriented
- Concept permanence
- Nonsemantic identifiers
- Polyhierarchy
- Reject ‘not elsewhere classified’
These features enhance the usability of medical vocabularies.
How does LOINC measure against Cimino’s Desiderata?
- Nonsemantic identifiers
- Polyhierarchy
- Does not include ‘not elsewhere classified’
LOINC is widely used for lab tests and clinical observations.
How does ICD-10-CM differ from LOINC?
- Semantic identifiers
- Monohierarchy
- Includes ‘not elsewhere classified’
ICD-10-CM is primarily used for diagnosis coding.
What is a ‘Value set’?
A collection of codes and terms that are appropriate for a specific data element
Value sets are essential for standardizing data in electronic health records.
Fill in the blank: A value set can be defined as _______.
[a collection of codes and terms appropriate to the data element]
What are the two types of value set definitions?
- Extensional
- Intensional
These definitions help clarify how value sets are constructed.
What does ‘Value set expansion’ refer to?
The process of adding new codes and terms to an existing value set
This is important for keeping value sets current with medical advances.
Define ‘Binding strength’.
The level of rigor with which a constraint should be enforced
Higher binding strength ensures better compliance with data standards.
True or False: Binding is a semantic task.
True
Binding involves linking concepts to their meanings.
What is ‘Model impedance’?
A barrier to semantic interoperability that arises from mismatched information models
It complicates the integration of different data systems.
List the options to produce interoperable messages using standard terminologies.
- Maps
- Native implementation
Each option has its advantages and challenges in maintaining standards.
What is ‘Native implementation’?
Implementing standard codes directly in the operational system
This approach minimizes maintenance overhead.
How do ontologies support semantic interoperability?
By specifying relationships and providing a framework for knowledge representation
This allows for more comprehensive data analysis.
What is the role of terminologies in clinical decision support?
They facilitate the intelligent use of information for quality measures and research
Accurate terminologies enhance the effectiveness of decision-making.
