ANSI Anti-Trust Policy:  Professional Associations, such as HL7, which bring together competing entities are subject to strict scrutiny under applicable antitrust laws. HL7 recognizes that the antitrust laws were enacted to promote fairness in competition and, as such, supports laws against monopoly and restraints of trade and their enforcement.

E-signature Update:  - NOT DISCUSSED

  • The e-signature draft was submitted to the PAC.  I did get a request from Christopher at Quest to quote a paragraph and am following up with PAC on when we are locked in enough to do so.


UP-44 -no value set content defined for v2 table 963 value set  - NOT DISCUSSED

  • We had discussed and taken a vote on this back on 2022-06-10, but I'm not sure at this point if that is still what we actually still will want to do.  If we discuss it again together hopefully we can decide if that is what we want or we can figure out a good alternative plan.

Add 'GTIN' to HL70301 and HL70203  - NOT DISCUSSED

Add "GTIN" to UniveralIDType ( to be able to specify that a Universal ID is of "GTIN" Universal ID Type.

This would help to apply to HD Data, EI Data, EIP Data, etc. the Universal ID Type "GTIN", examples are:

HD based Data (HD-2 (Universal ID) is of "GTIN" Universal ID Type:

  • MSH-3 (Sending Application), 
  • MSH-5 (Receiving Application), 

EI based Data (EI-3 (Universal ID) is of "GTIN" Universal ID Type:

  • SAC-3 (Container Identifier), 
  • SAC-4 (Primary (Parent) Container Identifier)
  • PRT-10 (Device ID)
  • PRT-16 (UDI Device Identifier)

EIP based Data (EIP-1-3 and EIP-2-3 (Universal ID) is of "GTIN" Universal ID Type:

  • SPM-2 (Specimen ID), 
  • SPM-3 (Specimen Parent IDs), etc.
    • Both of these are related to the work GS1 is currently discussing to maybe create a "serialized" GTIN for all containers which would be a worldwide unique code (woudl be default barcode on tubes, slides, tags etc) 

CX datatype uses HL70203 for example in PID-3 (not applicable), but maybe in OBX-5.

V2-Jira Review (time permitting)  - NOT DISCUSSED
