Assumptions and prerequisites

  • The PoS 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).

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.
