Solution Description

The FAST team is proposing a solution that will support a hybrid environment moving forward, including point-to-point, gateway, and intermediary models.   Minimum availability and performance requirements need to be established for any scale architecture including one or more intermediaries, with the requirement to support synchronous transactions and maintain “state” across intermediaries (i.e., systems remember preceding events that occurred across multiple systems or actors).  Intermediaries will need to support all FHIR workflow operations and be capable of handling volume, response time, and routing to all available endpoints.  Consistent support of metadata is also needed for routing through multiple intermediaries.  Finally, testing will validate conformance with these exchange and Service Level Agreement (SLA) requirements.

The goal is for ubiquitous access to permitted endpoints regardless of the architecture (i.e., point-to-point, one intermediary, or multiple intermediaries). The performance reliability and availability characteristics should be substantially the same for intermediary connections and point-to-point connections and must be acceptable for real-time information exchange where there is a provider/patient waiting for the response before clinical workflow can continue. The ultimate application user, system, and API endpoint should see the rest of the world as a consistent set of endpoints, regardless of whether there is one or more intermediaries sitting in the middle of the exchange.

Note: This proposed solution is still being refined as additional industry feedback is obtained, and is yet to be finalized.
