AHIC Healthcare Terminologies and Vocabulary Standards 3

Question 1

Semantic interoperability in health information exchange depends primarily on:

Accepted Answer

Consistent use of shared, standardized clinical terminologies across systems

Answer

Semantic interoperability requires that the meaning of exchanged data is preserved and understood consistently, which depends on shared use of standardized clinical terminologies.

Question 2

Post-coordination in SNOMED CT refers to the ability to:

Accepted Answer

Combine multiple codes at the point of use to express complex clinical meanings

Answer

Post-coordination allows clinicians to combine pre-existing SNOMED CT concepts (e.g., body site + finding + laterality) to represent complex clinical situations not captured by a single code.

Question 3

A General Equivalence Mapping (GEM) crosswalk between ICD-9-CM and ICD-10-CM is used to:

Accepted Answer

Facilitate translation of codes to support data analytics, reporting, and system migration

Answer

GEM crosswalks provide approximate mappings to support analytics, quality reporting, and system transitions, but do not guarantee clinical equivalence due to structural differences between the two systems.

Question 4

Which property of a well-designed clinical terminology ensures that concepts maintain consistent meaning over time, even as new versions are released?

Accepted Answer

Concept permanence

Answer

Concept permanence (from Cimino's desiderata) means that once a concept is assigned a code, that code retains its meaning permanently and is never reused for a different concept.

Question 5

In SNOMED CT, a 'poly-hierarchical' structure means that:

Accepted Answer

A concept can have multiple parents within the hierarchy

Answer

SNOMED CT is poly-hierarchical, meaning a single concept can have multiple parents (e.g., 'pneumococcal pneumonia' is a child of both 'pneumonia' and 'pneumococcal infection').
