Eve,

There may be only 4 distinct use-cases for UMA in healthcare. I wrote this in order to prepare for the legal subgroup this morning. Feel free to share if it's useful.

Alice-to-Alice N - The multiple portals problem - Alice wants to direct sharing herself
Alice wants to manage her EHR-1 and EHR-2 authorizations in one place. We call that place the AS.
Alice registers her AS with her practice’s EHR-1.
Alice registers her AS with another practice EHR-2.
From then on, Alice can sign-in to her EHR, view accounting for disclosures, and manage authorizations.

Alice-to-Custodian - Delegation to a custodian
Custodian creates an AS for Alice. Custodian has a sign-in to Alice’s AS.
Alice registers her AS with her PCP’s EHR-1.
Alice registers her AS with another practice’s EHR-2.
From then on, Custodian can sign-in to Alice’s EHR, view accounting for disclosures, and manage authorizations.

Alice-to-Bob Directed - Alice wants to authorize her PCP for directed sharing
Alice registers her AS with her PCP’s EHR-1.
The PCP shares an Alice-specific context with Bob.
Bob’s client EHR-2 presents claims to Alice’s AS, gets authorization.
EHR-2 accesses resource from EHR-1.

Alice-to-Bob HIE - Alice wants to be discoverable
Alice registers her AS with her practice’s EHR-1.
Alice picks up a flier for the state HIE with a Q/R code, reads their Privacy Policy
Alice signs-in into her AS and scans the Q/R code.
The HIE allows Alice to pick her discovery attributes, registers Alice’s AS.
Bob’s client signs into the HIE, discovers Alice, gets authorization to EHR-1.
