Genetic testing information standardization in HL7 CDA and ISO13606

Area of Science:

• Medical Informatics
• Genomics
• Health Data Standards

Background:

• Communicating patient genetic testing reports semantically interoperably is challenging due to document-based data storage.
• Lack of automated processing hinders secondary uses of genetic testing information, such as clinical trials and decision support.

Purpose of the Study:

• To develop semantically interoperable genetic testing reports.
• To enable secondary uses of genetic data through standardized modeling.

Main Methods:

• Modeled genetic information reports using Electronic Health Record (EHR) standards.
• Utilized the Implementation Guide for CDA R2 Genetic Testing Report (GTR) as a foundation.
• Developed archetypes for HL7 CDA and CEN/ISO 13606 standards.

Main Results:

• Created three archetypes conforming to ISO 13606.
• Developed three archetypes conforming to the HL7 CDA model.
• Successfully incorporated information from Usher Syndrome genetic testing reports and the GTR implementation guide.

Conclusions:

• The developed archetypes provide a foundation for semantically interoperable genetic testing reports.
• This standardization facilitates data exchange for communication and secondary applications in healthcare.
• The approach is validated and applicable to existing genetic testing report data.
