      • The FHIR data format is more straightforward than CDA
      • But additional issues need to be resolved
        • Data sharing agreement methodology
        • Limitations of query for reporting workflow
        • FHIR has less of an implementation history (and compiled industry experience) than CDA
        • HINs and HIEs don't fully support FHIR at scale (both policy and technical issues)
        • TEFCA is expected to be helpful for PH exchange
        • Attention from the FHIR community has mostly been on query, not on push messaging and the pre-definition of clear data sets that can be shared
  • US Public Health Profiles Library Update (20 mins)
    • HL7 USPHPL PH WGM 9-22.pptx
    • Starting with MedMorph and eCR profiles
      • Each IG currently contain their own profiles as the library hasn't been published yet

      • 54 issues submitted - 38 change requests
      • Ballot recon will happen Wednesday Q1
    • Talked to US Realm in Q3 to discuss a technical process
      • What to create a similar process to what US Core does in terms of validating that IG profiles are based on a library profile when an appropriate one exists (US Realm IG and the sponsor is Public Health)
      • Grahame says this is technically feasible
      • US Realm voted in favor
      • Someone will have to authorize exceptions
        • US Realm agreed that PHWG has the authority to create these exceptions
        • Exemptions granted my lead to changes to the US Profile Library if there is a general need for something that doesn't currently exist
      • Motion for the PHWG to accept responsibility for the variance process for IGs (Sarah Gaunt/AbdulMalik Shakir) 27-0-3
        • We need to develop the technical process with Grahame and a WG process
          • John and Sarah will work with Grahame
