Notes
  • Macro landscape
  • IZ roundtable
    • QBP & VXU on FHIR - move to proposing a FHIR solution to replace or augment current V2 work
    • Risk-based forecasting
    • Bulk FHIR
    • Immunization vaccine collaborative
    • ImmDS+HALO
  • AI & Intelligence (ONC)
    • Computable
    • Trustworthy (verified provenance, ensuring AI systems and downstream networks can rely on the data)
    • Fit-for-purpose
  • Adjacent HL7 Alignments
    • Conformance Work Group Reoob
    • Bulk FHIR Momentum - looking for partners
    • Terminology & Policy Shifts
  • IVC
    • Disconnected national code block global interop and pandemic response
    • NUVA - provide a common reference linking CVX, SNOMED CT, and ATC (align systems)
    • The Outcome - a share foundation ensuring global systems speak a single unambiguous vaccine language
  • Clarifying the Architecture: ImmDS v. CDS Hooks - we are standardizing the exchange of immunization, not standardizing clinic decision logic or replacing workflow tools. The CDS workgroup endorsed this seperation for a 2027 update
  • Input Challenge: Defining Contextual Conditions
    • Definition - expert-defined clinical categories asserted as neutral facts by the requesting system
    • Gap - constructing the EHR Bridge
  • IVC how it works with contextual conditions -
  • Next Steps
    • Bridge the EHR Gap - map contextual conditions to existing clinic FHIR profiles to resolve roundtable feedback
    • Scope QBP/VXU on FHIR - review existing US realm FHIR guidance with Keith Boone to identify gaps against CDC models
    • Pilot Bulk FHIR - identify concrete exchange scenario and willing partner (leveraging Envision/RI leads.
    • Advance IVC and IPS - analyze how SNOMED CT and IVC align within the IPS use case

Notes
  • FHIR R6 went through ballot and resulted in some tickets
  • Zulip chat to how reactions are documented - https://chat.fhir.org/#narrow/channel/294552-Patient-Care-WG/topic/Reaction.20vs.20Manifestation/with/626177674
  • Comparing to allergy and intolerance
  • Last chance to get it right before Immunization becomes normative
  • Reaction and manifestation discussion - concerns about reducing from 0..* to 0..1 - breaking change
  • Immunization does not allow for AI to be an information source
  • Series Dose and Dose Number - provider indicates intent 2nd of 3 dose series for example - https://ginoc.io/jira-ticket-site/discussion/index.html#/ticket/FHIR-58387?wgKey=value%3APublic+Health
