FHIR Infrastructure Work Group Maturity Level : N/A Ballot Status : Informative

This specification is currently in its third round of trial use. While some parts of the specification are mature and stable, and HL7 is focusing on moving these to a formal standard, much work remains to be done in other areas. The following general areas of functionality have been deferred to a future version, or are incompletely covered in this version:

  • An alarm resource to represent current issues with the patient (e.g. device created)
  • Concern Tracking
  • Aggregated Data Reporting including Public Health Reporting
  • One or more resources for Advance Care Directive / Power of Attorney
  • A full server side query framework

For some of these, some draft content is included in the specification for implementer consideration.

In addition, there are a number of specific notes in the specification requesting feedback from implementers:

  • AllergyIntolerance : new codes needed for certainty?
  • AllergyIntolerance : How should "No "No Known Allergies" Allergies" be represented?
  • Appointment : Values for Appointment.priority: how interoperable are they
  • BodySite : Should it be an independent resource or a datatype? ClinicalImpression : General Questions about use
  • Clinical Reasoning : Multiple questions about implementation and usage
  • Composition : Is title different to type? and open questions about document signatures
  • Condition : How should "No "No Known Problems" Problems" be represented?
  • DataElement Device : Questions about instance vs kind, and multiple UDIs
  • DeviceRequest : Should DataElement, this be rolled into StructureDefinition as a Logical Model? combined with SupplyRequest?
  • Markdown DiagnosticReport : Probable that will recommend/require CommonMark in release 4 - implementation consequences? Request for comments on Clinical Genomics approach
  • Extensibility Exchange : Do we need to Should support modifier extensions on extensions? for ProtocolBuffers be added to the specification?
  • RESTful API : Consequence of side effects in batches and transactions?
  • RESTful API : Should servers maintain ids when processing transactions? RESTful API : What are the documentation requirements around transaction integrity?
  • Managing Resource Identity Immunization : Mandating Identification practices Question about doseSequence and several new elements
  • ImmunizationEvaluation : Question about general recommendation design
  • ImmunizationRecommendation : Question about recommendation cardinality and general recommendation design
  • Media : Request for cross-system interoperability? comments on changes, and relationship with Observation
  • Narrative : Should narrative support multiple languages more directly?
  • Observation Patient : Request for feedback comments on using the lastn operation and whether it should be applied to other resources several changes
  • Operations Patient : Do we need a way to execute operations asynchronously? Request for comments on Clinical Genomics approach
  • Patient : Should linking/merging affect the RESTful API?
  • Profiling Resources : Need feedback on using system profiles
  • JSON-LD format : Need feedback on the JSON-LD format and it's usefulness References between Resources : Do we need to allow contained resources that reference the container?
  • Safety : Request for comments about further development
  • Search : does text search need to be standardized?
  • Search : Problems with which elements are marked as 'included in summary'
  • Security : Feedback about signatures on RESTful interfaces sought
  • Subscription : messaging details still to be resolved
  • ServiceRequest : Various Implementation/Design questions
  • SupplyRequest : Should this be combined with DeviceRequest?
  • Persistent Store/Database : Is a standard extension required for resolved links?
  • Workflow : several implementation questions
