Background

360X describes the use of referral-specific payloads that enable the management of end-to-end (closed-loop) referrals. Given that the TEFCA "push" interactions are based on XCDR, a related IHE profile to XDR, there could be a relatively straight-forward path for enabling 360X on TEFCA. 

In September and October of 2024, the 360X project distributed a questionnaire to potential interested parties.

Approach

The initial approach for this effort is in two main areas:

1. Enable the mapping of the referral targets (currently Direct addresses in 360X) to TEFCA endpoints and Responding Nodes, and describe the routing. This includes:
   - enhancing the provider directory to indicate support for 360X
   - TEFCA or IHE profiling how SubmissionSet.intendedRecipient and author can be used to indicate the precise recipient and sender (most people will probably want to use Direct address for this purpose for now, but we would want to consider how other identifiers might be used).
   - requirements on the TEFCA Responding Node to be able to understand those values and route the message accordingly, or return an error if the value is unrecognized and/or routing is not possible. 
2. Describe an XCDR transport option in the IHE specification that enables the sending and receiving of 360X transactions across communities, allowing TEFCA to then reference it.
