FHIR Modernization Services

Modernize legacy systems like HL7 v2 or CDA by migrating to FHIR standards. Transform and validate your data for seamless compliance and interoperability.

HL7 v2 Message Transformation into FHIR Resources

Healthcare organizations often rely on HL7 v2 messaging standards, which can be complex, unstructured, and inconsistent across different systems. Our migration services:

  • Extract and convert HL7 v2 segments (e.g., ADT, ORM, ORU, VXU) into corresponding FHIR resources (e.g., Patient, Encounter, Observation, MedicationRequest).
  • Preserve message integrity and structure while adapting to the modern, RESTful FHIR framework.
  • Support multi-format inputs, including HL7 v2, CCD, XML, and JSON, for flexible and accurate data transformation.

Automated Data Validation to Ensure Accuracy

Migrating healthcare data requires precision and compliance to maintain data integrity and usability. Our automated validation processes ensure:

  • Schema conformance checks to validate migrated data against FHIR standards.
  • Data integrity assessments to prevent duplication, errors, or loss during transformation.
  • FHIR resource validation tools to confirm compliance with US Core, Argonaut, and other FHIR implementation guides.
  • Automated testing frameworks to detect and resolve discrepancies before deployment.

Scalable Migration Strategies for Large Datasets

Handling millions of patient records, clinical encounters, lab results, and medication histories requires an efficient, scalable approach. We provide:

  • Batch and incremental migration strategies to minimize disruption and ensure smooth transitions.

    Frequently Asked Questions

    HL7 FHIR (Fast Healthcare Interoperability Resources) is a standard developed by Health Level Seven International (HL7) to enable seamless electronic exchange of healthcare data. It uses modern web technologies like RESTful APIs to make data accessible, computable, and interoperable.

    Unlike older standards such as HL7 v2 or CDA, FHIR is built with modern web technologies, uses granular resources instead of monolithic documents, and is developer-friendly. This makes it faster and easier to implement while offering greater flexibility for various use cases.

    FHIR supports robust security protocols like OAuth 2.0 and TLS to protect data in transit. However, healthcare organizations are responsible for implementing additional security measures and complying with regulations like HIPAA or GDPR to ensure data privacy and security.

    APIs are the backbone of FHIR, enabling seamless communication between systems. FHIR uses RESTful APIs to retrieve, update, or share specific data in real time, fostering interoperability and simplifying app development.

    FHIR organizes healthcare data into modular components called resources (e.g., Patient, Observation, Medication). These resources are standardized, making it easier to exchange data between systems while maintaining a consistent structure.

    Yes, FHIR can be integrated with legacy systems through middleware or adapters that map older data formats to FHIR standards. This allows organizations to modernize their interoperability capabilities without completely replacing existing systems.

    FHIR’s lightweight, RESTful APIs are perfect for mobile and web applications. Developers can use FHIR to retrieve and display patient data, integrate with wearable devices, and create innovative apps for better patient engagement and care delivery.

    Interoperability is the ability of different healthcare systems, applications, or devices to exchange, interpret, and use data effectively. FHIR promotes interoperability by providing a common standard for sharing and accessing healthcare data.

    FHIR is increasingly being adopted worldwide by governments, healthcare organizations, and technology vendors. Initiatives like the US CMS Interoperability Rule and Europe’s focus on digital health are driving its implementation globally.

    FHIR is continuously updated by HL7 to address emerging needs, such as supporting AI-driven solutions, integrating with IoT devices, and enhancing data exchange for public health emergencies. Its adaptability ensures relevance for future healthcare innovations.

    CDA (Clinical Document Architecture) focuses on document-based data sharing, while FHIR offers a modular, resource-based approach. FHIR’s use of APIs and web technologies makes it more flexible and developer-friendly for modern healthcare applications.

    Start by evaluating your current systems for interoperability readiness, training your team, and consulting with FHIR experts. Implement pilot projects and gradually expand to fully leverage FHIR’s capabilities.
