2.22 Outstanding Issues

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 Known Allergies" be represented?
• Appointment: Values for Appointment.priority: how interoperable are they
• 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 Known Problems" be represented?
• Device: Questions about instance vs kind, and multiple UDIs
• DeviceRequest: Should this be combined with SupplyRequest?
• DiagnosticReport: Request for comments on Clinical Genomics approach
• Exchange: Should support for ProtocolBuffers be added to the specification?
• RESTful API: Consequence of side effects in batches and transactions?
• RESTful API: What are the documentation requirements around transaction integrity?
• Immunization: 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 comments on changes, and relationship with Observation
• Narrative: Should narrative support multiple languages more directly?
• Patient: Request for comments on several changes
• Patient: Request for comments on Clinical Genomics approach
• Patient: Should linking/merging affect the RESTful API?
• Profiling Resources: Need feedback on using system profiles
• 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
