An integration foundation for connected hospital workflows
Connect HIS, clinical and departmental systems through a governed exchange layer. ZeroOne combines healthcare standards, integration-engine capabilities and AI orchestration to coordinate data and workflow across the hospital environment.
A managed exchange layer for the systems you already have
Use a suitable integration engine to support HL7 messages, FHIR resources and APIs documented with OpenAPI 3.0. Where needed, change data capture (CDC) tracks database updates, while an Anti-Corruption Layer (ACL) translates between legacy and modern data models.
Receive and route
Accept supported messages and events, identify the appropriate destination and manage delivery state.
Validate and transform
Check agreed data structures, profiles and mappings before information reaches a receiving system.
Reconcile context
Use patient indexes (MPI/EMPI) and master data management (MDM) to reconcile identities and reference data, with defined systems of record (SoR) and review paths for uncertain matches.
Recover and replay
Handle failures through bounded retries, quarantine queues and controlled replay without duplicating transactions.
Observe and trace
Record message lineage, acknowledgements and operational events for support and investigation.
Coordinate with AI
Use AI assistance for mapping proposals, exception analysis and bounded agent workflows, with approved execution paths.
Use the right standard for the exchange
- Exchange standards
HL7 v2
Event and message exchange for established hospital interfaces, including ADT, orders and results where supported
HL7 FHIR
Resource-based exchange and service interfaces; version and implementation guide selected for the participating systems
HL7 CDA
Structured clinical-document exchange where required by the environment
DICOM and DICOMweb
Imaging information and supported web-based imaging workflows across RIS, PACS and related systems
- Implementation profiles
IHE profiles
Defined implementation patterns that combine standards for specific cross-system workflows
- Terminology and classification
SNOMED CT
Clinical meaning and terminology mapping where applicable
LOINC
Identifiers for observations, measurements and documents, including laboratory content
ICD-10 and ICD-11
Classification and coding appropriate to the jurisdiction and use case
UCUM
Consistent representation of units of measure where applicable
- Access patterns
SMART on FHIR
Appropriate application and backend authorisation patterns for FHIR-based access
FHIR adoption does not by itself provide security or full semantic interoperability, and not every system supports the newest release or every operation. Versions and profiles are confirmed per participating system.
Coordinate the workflow through agents and governed tools
An orchestrator can select a permitted workflow, ask one agent to retrieve the required information and ask another to prepare or carry out an authorised action. Reusable connectors and clear policies reduce repeated point-to-point workflow work while keeping system boundaries explicit.
Approved ADT or workflow event
Policy-governed AI orchestrator
Retrieval agent
Approved HIS/EMR connector
HIS / EMR
Task agent
Approved departmental / workflow connector
Departmental or workflow system
Validated response or operational task, with acknowledgement
Identity
Permission checks
Schema and terminology validation
Human approval where needed
Audit trail
Exception handling
Agents reach hospital systems only through approved connectors and tools. The orchestrator coordinates the sequence; it does not replace system databases or grant access on its own.
Example. When an admission event is received, a retrieval agent can obtain authorised patient and encounter context. A workflow agent can then prepare a non-clinical coordination task for the appropriate team. Approved rules determine what can execute automatically and what requires staff review.
