Public health and national systems
Open Health Information Exchange (OpenHIE)
OpenHIE is an open community and reference architecture for national health information exchange. It describes shared components, such as a client registry, facility registry, shared health record and interoperability layer, and the workflows that connect them.
Why it matters
A national health information system is not one product. It is a set of registries, records and reporting tools that must agree on who a patient is, where care happened and what was done. OpenHIE gives ministries a shared pattern for those parts, so procurement can specify how each system connects rather than buy one system to do everything.
Key points
- The architecture specification is intended as a pattern for the key components of a health information exchange, reflecting the consensus of its Architecture Review Board [1].
- It names IHE profiles as the building blocks of its data exchange workflows, with FHIR resources as part of the standards picture [1].
- Components include registries for clients, facilities, health workers and terminology, a shared health record, a health management information system and an interoperability layer [2].
- The shared health record supports three exchanges: querying a patient's previous encounters, providing data to the record, and requesting a document on demand [3].
In Moana
Moana serves as the point of service system and shared patient record within an OpenHIE style architecture, exchanging data through FHIR R4 and reporting aggregates to the national HMIS.
