Notes
  • FHIR-58655
    • Comment so far - Only need vaccine, not vaccine group
    • Similar to preferable vaccines in V2
    • Target disease is functionally equivalent to vaccine group
  • FHIR-58952
    • Only one target disease but consider expanding to allow multiple target diseases
  • FHIR-59485
    • Make it codable concept but still can do a string
    • no concerns raised by the group for this direction
  • FHIR-59486
    • Same as evaluation - no concerns
  • FHIR-59487
    • For evaluation
    • adding a season
    • no concerns raised with this direction
  • FHIR-59488
    • For recommendation
    • adding a season
  • FHIR-59489
    • On recommendation
    • can now say which does number you are on but no way of saying how many doses remain
    • can move forward as proposed

Structural/definitional
*FHIR-58952 - MULTIPLE TARGET DISEASES IN IMMUNIZATION EVALUATION
*FHIR-58655 - ImmunizationRecommendation VaccineCode has a conflated definition
*FHIR-59485 - ImmunizationEvaluation: Change 'series' from string to CodeableConcept
*FHIR-59486 - ImmunizationRecommendation: Change 'series' from string to CodeableConcept

Handled in ICE FHIR API extensions
*FHIR-57247 - ImmunizationRecommendation.authority needs to be moved under recommendation backbone element
*FHIR-56990 - ImmunizationRecommendation.authority cardinality expansion
*FHIR-56989 - ImmunizationEvaluation.authority cardinality expansion
*FHIR-59487 - ImmunizationEvaluation: Add season
*FHIR-59488 - ImmunizationRecommendation: Add season
*FHIR-59489 - ImmunizationRecommendation: Add seriesDosesRemaining

Other open questions
*Option for recommendation-related URL: PlanDefinition, Library, Device, and Device Definition
Notes
  • Working on FHIR tickets.
  • Comment from participant: The scenario I was considering is that there is a provider. Provider is using Authority A for a recommended influenza vaccine schedule and Authority B for a TB schedule. Patient 1 has received vaccinations for both influenza and TB. How is that represented? (can be addressed offline/different time and place)
  • Another topic: How do we message at the technical level to share how the logic got to the answer. HLN software provides a URL for this. Maybe PlanDefinition, Library, DeviceDefinition. Device seemed to narrow but actually it's more broad. Probably more than a URL, maybe version number and data. PlanDefinition had some references to CDS. Action item is to do more investigation.
    • The term needed is something like "clinical decision support rule that is backing the recommendation for a particular vaccine group".
    • Need this at the recommendation backbone element.
    • URL can be displayed as additional documentation
    • Explains the logic that was used to make the recommendation
  • Discussed 7 tickets that would be useful to move.

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
