1.6 Outstanding Issues

This specification is currently in its second round of trial use. Much work remains to be done.

Specifically, there are still many outstanding questions about the Request/Fulfillment cycle (Order/ OrderResponse and how various statuses and workflows associated with requests, as well as how proposals cascade to plans to orders to downstream/encoded orders, etc. This is a matter of ongoing investigation.

In addition, the following general areas of functionality have been deferred to a future version:

  • Adverse Event Reporting
  • An alarm resource to represent current issues with the patient (e.g. device created)
  • Concern Tracking
  • Clinical Studies and Protocols
  • Aggregated Data Reporting including Public Health Reporting
  • Payment related resources, and specifically, an Account resource for payment tracking
  • One or more resources for Advance Care Directive / Power of Attorney
  • Use of RDF
  • 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: how to report 'no known allergies' of various flavors
  • Appointment: suitability of Appointment.priority values
  • BodySite: suitability of this as a resource?
  • CarePlan: 2 questions about usage
  • ClinicalImpression: general usage questions
  • Composition: question about title being mandatory, and about signatures
  • Invariants: is there a replaceement for XPath?
  • DataElement: question about relationship between DataElement and other resources
  • Markdown: which markdown flavor can we settle on, if any?
  • DiagnosticReport: relationship with Observation
  • RESTful API: question about using the PATCH operation
  • RESTful API: what should we do about side-effects and transactions?
  • RESTful API: Transaction integrity and introspection
  • Resource Identification: identifier policy rules?
  • Messaging: what additional events should be defined?
  • Operations: should it be possible to execute operations asynchronously?
  • Patient: what effect linking/merging/unlinking should have on other functionality such as the GET operation?
  • Patient: Comment on MPI search query sought
  • Profiling: Note about need for feedback about use of profiles
  • References: Should inside out containment be allowed?
  • RiskAssessment: General usage questions
  • Search: how much should text search be standardised?
  • Search: Should additional rules about how _include works be made?
  • Security: Using signatures with RESTful interfaces is a poorly understood area
  • Subscription: Use with messaging is still to be clarified
