201701 Resource Subscription Track
Return to January 2017 Proposals
FHIR Resource Subscription Track
Submitting WG/Project/Implementer Group
FHIR Management Group (FMG) (Proposed) Healthcare Services Platform Consortium (HSPC) (Proposed)
Justification
As part of the Workflow Module, the FHIR specification includes capabilities for a client to subscribe to receive notifications to resources that have been created or updated. The Subscription resource is used to define a push based subscription from a server to another system through a number of defined “channels”. The subscription includes criteria in the form of a search string that, when a resource is created or updated that match it, trigger a notification from the server through the channel specified in the original subscription request. Depending on the subscription request and channel, the notification may take the form of a simple reference, either to the search string or matching resource, or may include the content of the matching resources.
Proper workflow management and information orchestration is critical for any diverse and complex interoperable health IT ecosystem. A critical component of enabling effective workflow is the ability to receive updates on particular pieces of information of interest. For example, if a patient has a number of tests run during a specific encounter the results of those tests may not be immediately available. A provider that is interested in those results when they arrive could subscribe for notifications about the creation or updating of Observation resources that are associated with that encounter. Another example is where a provider may be interested in getting notifications on the progress of a specific patient’s condition.
The purpose of this track is to gain more implementer experience in the Subscription resource and identify areas where more definition may be needed in the specification and help move this resource to a higher maturity level.

Please sign up!
If you're working on a server, please complete the "servers" tab of the Signup Spreadsheet **This time around you'll need to update the `status` flag to indicate whether you've begun work (or completed work), so clients will know when to start testing.** You'll also share details about how a developer can obtain OAuth client credentials (`client_id` for public apps, or a `client_id` and `client_secret` for confidential apps) as well as user login credentials. You might consider simply sharing a set of fixed credentials in this spreadsheet, or else directing users to a web page where they can complete self-service registration. If absolutely necessary, you can ask developers to e-mail you directly.
If you're working on a client, please complete the "clients" tab of the Sprint 4 Spreadsheet. You'll also need to update the `status` flag to indicate whether you've begun work (or completed work).
Roles
Please include information here regarding how much advance preparation will be required if creating a client and/or server.
FHIR Subscription Client
Enable creating, updating, and deleting of subscription resources that include a search string criteria.
FHIR Server
Support the receiving and processing of subscription resources and provide notifications for resources through the requested channel (if the channel is supported).
Subscription Notification Receiver
Receive notifications from the server over the channel identified in the subscription resource. Query for the resource information if not provided in the notification payload. (NOTE: The notification receiver may, but does not have to, be the same as the subscription client, particularly considering the receiver may be a mobile device (SMS) or secure emailing system)
