1.7 Open Issues

There are a number of issues in which input based on implementation experience is specifically sought during the trial use phase:

• Conformance: How system profiles are used
• Order: The need for additional kinds of order to be defined
• Resource Identification: Managing resource identification in distributed systems
• Search: How should text search be standardized?
• Search: How much should _include be standardized?
• Security Labels: How much policy can be standardized, and how does this impact on this specification?
• Security: What use cases are there for digital signatures?
• Messaging: Messaging has not yet been well-exercised at connectathon, so feedback based on implementation is welcome

In addition, there are future proposed resources:

• A notification resource for creating and recording notifications between parties
• An alarm resource to represent current issues with the patient
• A person resource to support person registries
• An appointment resource for making and tracking arrangements around the future of care
• Payment related resources, and specifically, an Account resource for payment tracking
• Possibly a way to define particular queries (finer detail than Profile provides)
• One or more resources for Advance Care Directive / Power of Attorney

Note that other resources beyond these may be anticipated.

In addition to these, further work is planned around tracking and reporting clinical observations / vital signs, and supporting remote consultations / telehealth.
