# Health Data Integration

Facilitate interoperability between health IT systems including EHR, HIE, and clinical decision support through HL7, FHIR, and other healthcare data standards.

## Overview

This skill enables integration of healthcare information systems. It encompasses interoperability standards implementation, data exchange configuration, and system integration to support seamless health information sharing.

## Capabilities

### Interoperability Standards
- HL7 v2 messaging
- HL7 FHIR resources
- CDA document exchange
- CCDA implementation
- Direct messaging

### System Integration
- EHR integration
- HIE connectivity
- Lab interfaces
- Pharmacy integration
- Device connectivity

### Data Exchange
- ADT notifications
- Clinical summaries
- Lab results
- Medication data
- Imaging reports

### Data Quality
- Data validation
- Mapping and transformation
- Error handling
- Reconciliation
- Audit logging

## Usage Guidelines

### Integration Process
1. Define integration requirements
2. Assess system capabilities
3. Select appropriate standards
4. Design interface specifications
5. Develop and configure
6. Test thoroughly
7. Deploy and monitor

### FHIR Implementation
- Identify required resources
- Configure API endpoints
- Implement authentication
- Handle search parameters
- Manage subscriptions

### Data Governance
- Establish data standards
- Define ownership
- Implement access controls
- Maintain audit trails
- Ensure privacy compliance

Overview

This skill enables reliable interoperability between health IT systems by implementing HL7, FHIR, CDA, and related healthcare data standards. It focuses on connecting EHRs, HIEs, labs, pharmacies, and devices to support secure, auditable clinical data exchange. The skill improves data quality, streamlines interfaces, and helps operationalize clinical decision support integration.

How this skill works

I inspect system capabilities, select standards, and create interface specifications for message and API exchange. Implementations cover HL7 v2 message flows, FHIR resources and REST endpoints, CDA/CCDA document exchange, and Direct messaging. I include data mapping, validation, error handling, audit logging, and deployment checks to ensure reliable runtime behavior.

When to use it

  • Connecting a new EHR to an HIE
  • Delivering lab, imaging, or ADT feeds to downstream systems
  • Implementing FHIR APIs for clinical data access
  • Integrating clinical decision support with live patient data
  • Standardizing data exchange during mergers or platform migrations

Best practices

  • Start with a clear requirements and capabilities assessment for every integration project
  • Adopt implementation guides and conformance testing for HL7/FHIR profiles used
  • Define canonical data models and reusable mappings before coding
  • Enforce authentication, authorization, and audit trails aligned with policy
  • Automate validation, reconciliation, and monitoring to detect drift and errors

Example use cases

  • Build HL7 v2 ADT and lab interfaces from hospital middleware to a cloud EHR
  • Expose FHIR Patient and Observation resources for a CDS service and manage subscriptions for notifications
  • Translate legacy lab results into FHIR DiagnosticReport and push to an HIE
  • Implement CCDA document exchange for post-acute care transitions with audit logging
  • Integrate pharmacy fill data and medication lists across systems to maintain medication reconciliation

FAQ

Which standards should I choose for a new integration?

Choose based on use case and partner capabilities: HL7 v2 for event-driven feeds (ADT, labs), FHIR for APIs and CDS, and CDA/CCDA for document exchange. Use implementation guides to narrow resource sets.

How do you ensure data quality across systems?

Use canonical mappings, field-level validation, transformation rules, reconciliation jobs, and audit logs. Combine automated tests with periodic sampling and provider feedback loops.
