Semantic Difficulties in FHIR 'Conditions'

Area of Science:

• Health Informatics
• Clinical Data Standards
• Electronic Health Records

Background:

• The Fast Healthcare Interoperability Resources (FHIR) standard aims to standardize electronic health data exchange.
• Preventing semantic ambiguity is a key goal of the FHIR standard.

Purpose of the Study:

• To evaluate the semantic clarity of FHIR's Condition resource, specifically the 'clinical status' and 'verification status' elements.
• To identify semantic difficulties within the FHIR Condition resource definitions and allowed values.

Main Methods:

• Analysis of the FHIR Condition resource specifications.
• Focus on the 'clinical status' and 'verification status' elements and their combined usage.
• Identification of semantic issues in element definitions and value sets.

Main Results:

• FHIR's 'clinical status' and 'verification status' definitions present semantic difficulties.
• Disjunctive descriptions and pseudo-synonyms without clear distinctions were found.
• Insufficient discrimination between evidence and its subject matter was identified.

Conclusions:

• The FHIR standard, in its current form, may not fully prevent semantic ambiguities in clinical data exchange.
• Further refinement of FHIR Condition resource elements is needed to improve clarity and reduce potential misinterpretations.
