Minutes

Minutes/Conclusions Reached:

1. Roll Call
2. Review draft agenda
3. Introductions
4. Task Force:
   • Definition - a purpose tasked committee with a lifetime to match the issue
   • Objectives: to define a conceptual model for UDI to ensure interoperable implementation across the suite of HL7 standards (v2, v3 message4, v3 CDA, FHIR

   Timeline: 3 weeks if possible (prior to harmonization)

   • Goals for today: introduce the issue, outline the goal(s), start developing the questions, and engage participants in seeking the answer.
5. UDI Presentation from Terrie Reed (FDA)
   • UDI means Unique Device Identification. The UDI is a series of numeric or alphanumeric characters that is created through a globally accepted device identification and coding standard. It allows the unambiguous identification of a specific medical device on the market. The UDI comprises the UDI-DI and UDI-PI.

   Note: The word Unique" does not imply serialization of individual production units.

   • Discussion: She shows a slide show on the current status of UDI.
   • Grahame asks if HL7 should be involved in the API development to the GUDID. How to retrieve from the GUDID not yet addressed.
   • Hans asks about the use cases for when to communicate UDI or its DI/PI components?
   • Paul Schluter notes that Terrie wanted ASCII string display. How must it be stored and displayed for EHRs - components versus the whole. If you break it up into constituent parts you can't reassemble it for human readable format with the PI at the manufacturer's discretion. Recommend communicating entire UDI as known and allow the application to parse / use what they need of it. User visual validation would require the parentheses to be displayed.
     • Good things:
       • Always transmit the entire string
       • The string should be human readable
       • The contents should be parseable
   • International device regulator's forum has been active for years and Terrie can refer to a white paper.
   • Paul K. describes use case with G10 example, vs ISBT format
   • Configuring bar code readers rendering same display values is an issue.
   • HL7 needs to specify what we're storing, knowing if it's a codeable structure and what the decoding would be. John M notes that there are OIDs, URIs and other universal global IDs but we don't try to decompose them.
   • Grahame notes he had investigated they will need to use specially configured bar code readers for this UDI. If we state the human-readable format is what needs to be exchanged because that is the format from which all can use it, since we need a separate bar code reader anyway.
   • Hans notes that an EI with assigning authority might indicate how the code is used. However when you're scanning how do you indicate that.

At time, Paul is asked about inviting Christian Hay. This might be difficult time for him but we can invite him. What about HIBCC - Terrie can invite a contact. Hans asks about X12?

Schedule for next week at same time for next two weeks

Paul asks that others provide their perspectives, V2, FHIR, etc.

Woody sends the link to Grahame's Blog on UDI is: http://www.healthintersections.com.au/?p=1730

Grahame also asks about non-patient devices versus patient specific items like blood bags etc. John notes there are legacy identifiers in devices, like Continua notes JD.
