HTA HL7 & IHTSDO have a collaboration agreement to work together to improve the quality of HL7 Value Sets. Progress has been slow but picking up steam. It is very important that HL7 respond in a timely fashion. However, various difficulties have been encountered.

8. © 2014 Health Level Seven ® International. All Rights Reserved. HL7 and Health Level Seven are registered trademarks of Health Level Seven International. Reg. U.S. TM Office. HTA Difficulties include: 1. Different HL7 Product Families create and store value sets differently; 2. Common tooling does not exist to perform these actions across the product families; 3. The quality of the existing value sets is highly variable; 4. There are very few resources within HL7 that have the capability of responding to these difficulties.

9. © 2014 Health Level Seven ® International. All Rights Reserved. HL7 and Health Level Seven are registered trademarks of Health Level Seven International. Reg. U.S. TM Office. Approach We need to bring together resources to:  Identify a set of use cases. For example, FHIR, CIMI, HL7 CDA, etc.  Identify the corresponding value sets  Undertake the necessary remodeling, curation and quality assurance ensuring fitness for purpose.

10. © 2014 Health Level Seven ® International. All Rights Reserved. HL7 and Health Level Seven are registered trademarks of Health Level Seven International. Reg. U.S. TM Office. Approach (cont.)  Recognize the international standards that can be used across different development and run-time architectures;  All of the above will give us requirements for the tooling and process that must be developed. The result of all of the above will give us the necessary information to create a road map to review all HL7 value sets and identify the resources required to complete the project management work plan and transition.
