ADT^A08 - IHE ITI-8 Transactions
Assumptions and Prerequisites
The Point-of-Service system is a trusted application known by the HIE and it is registered with the interoperability layer to be able to send and receive data securely (Common message security workflow).
The Patient to be updated is assumed to already exist in the Client Registry.
Actors
PoS - The point of care system that captures patient identifiers, is responsible for sending the identifiers to the HIE.
IL - Mediates the transactions between the PoS system and the Client Registry.
CR - Manages patient demographics and identifier details.
