Meeting Minutes from Discussion

1Agenda Review and Minutes Approval (5 min)

Motion to approve meeting minutes from 2020-03-12 (Craig, Crystal)

  • Approved (27-0-0)
2COVID-19 response update (Robert Worden) (20 min)

This is a continuation of the discussion from last week's call as well as discussion on the PHWG listserv. See supporting material.

This is a personal effort from Robert.  This item has been tabled as a Board agenda item.  There are concerns that subject matter experts are not available to provide input to this exercise as they are busy responding to the pandemic. Participants are encouraged to provide feedback to Robert if possible however, it is not possible to do any meaningful engagement with subject matter experts.

Motion: The PH work group convey to the HL7 Board that this document does not adequately represent existing or ongoing work and should be reworked before it is presented to the Board for consideration.  Furthermore more informed alternatives cannot be provided by the WG as subject matter experts are working heads down in dealing with the pandemic (John Loonsk, Alean Kirnak)

  • Approved (35-0-1)
  • PHWG co-chairs to send a note to Karen, cc'ing Chuck, Wayne, Walter, Austin and Robert

4  starting Page 33 Patient Identifier Cross-Referencing (PIX).    

  • Note Figure 5-1:  the “Patient Identity Feed” is the ADT
  • Note Figure 5-1.1:  transactions Patient Identity Feed ITI-8 and Patient Identity Management ITI-30 describe the ADTs. 
  • ITI-30 in particular is relevant to immunization registries and other pediatric databases
  • Note references to Pediatric Demographic Option starting Page 36 Patient Identity Feed ITI-8.

  • Note top of Page 37 Section 3.8.2.  Note the reference to Document Registry.  This is a clue that XDS also uses Patient Identity Feed.  XDS registries/repositories are commonly found in Health Information Exchanges (HIEs), enterprise systems, and elsewhere.    
  • Note Figure 3-8.1 indicates the ADT trigger events used by ITI-8.  These include A01, A04, A05, A08 and A40.
  • Note references to Pediatric Demographic Option.  starting Page 12 Patient Identity Management ITI-30.

  • Note and Page 13 setting forth inclusion of ADT trigger events A28, A31 and A47.   
  • Additionally, implementers of the “merge” option must include A40 (merge two patients); implementers of the “link/unlink” option must include A24 (link) and A37 (unlink). Note the concept of “option” in the IHE framework.  Connectathons typically offer separate tests for the base profile and for the addition of the option.  This allows systems that don’t implement (in this case) merges and/or link/unlinks to pass on the base profile, while systems that do implement them can pass on those options.   The 2.8.2 IG might mirror this approach by setting these trigger events forth as options.
  • Also note that “merge” has no inverse operation.    This derives from the HL7 base standard.  There is no such thing as an “unmerge”. 
  • Note describes the additional requirements of  Pediatric Demographic Option.
  • Note Figure 3.30-3.  Pediatric Demographic Option creates additional constraints on everything with “Note 1” as described in the footnote.
