Trusted identity and directories

The national exchange layer
Connect care without replacing every system.
PHX provides the trusted exchange, governance, and operational layer between existing public and private health systems—so information can move with purpose, accountability, and country control.

Core capabilities
A shared foundation for a connected health ecosystem
PHX groups national capabilities into clear trust and exchange domains. Detailed internal methods remain protected; public interfaces and assurance stay verifiable.
Care
Care exchange and referrals
Authorized clinical exchange, accountable cross-facility referrals, acknowledgements, and continuity-of-care pathways.
Trust
Consent, privacy, and audit
Purpose-aware decisions, minimum-necessary access, privacy controls, and durable evidence of sensitive actions.
Operations
Interoperability operations
Conformance, routing health, data quality, terminology, acknowledgements, and recoverable exchange operations.
Public health
National insight
Privacy-protected surveillance, coverage, trends, and programme monitoring for authorized national audiences.
Ecosystem
Governed participation
Clear onboarding paths for public and private facilities, insurers, regulators, programmes, and software vendors.
How it works
Four layers, one accountable exchange
Connect
Existing systems join through approved interfaces and country-defined onboarding requirements.
Govern
Identity, purpose, consent, policy, and institutional roles determine what is allowed.
Exchange
Authorized information moves with traceability, acknowledgement, and operational safeguards.
Act
Care teams coordinate care while authorized leaders receive privacy-protected national insight.
Product boundary
What PHX deliberately does not replace
PHX does not duplicate everyday hospital operations. It connects the ecosystem around them.
Facility operations stay local
Billing, dispensing, ward management, laboratory workflow, and daily clinical operations remain in facility applications.
Policy stays authoritative
The user interface explains policy; the trusted service layer remains the source of truth for authorization and exchange.
Data access stays bounded
Partner and population views use authorized, de-identified aggregates—not a path into individual patient records.
