FHIR can provide a standardized framework for exchanging healthcare information through APIs. This can help applications retrieve and exchange relevant information more consistently.
HL7 FHIR can support interoperability across:
Hospitals
Clinics
Physician practices
Laboratories
Pharmacies
Insurance organizations
Telehealth platforms
Patient applications
Remote monitoring systems
Medical devices
Interoperability can improve access to information while reducing unnecessary manual data entry.
HL7 vs. FHIR: What Is the Difference?
HL7 is an international standards organization that develops standards for healthcare information exchange. HL7 standards include several approaches for exchanging healthcare information.
FHIR is one of the standards developed by HL7. It provides a modern framework that uses web technologies and APIs to exchange healthcare data.
Traditional HL7 standards, such as HL7 v2, commonly use message-based communication. FHIR uses resources that applications can exchange through APIs.
Both approaches remain relevant in healthcare environments. Organizations may need HL7 v2, FHIR, or both based on their existing systems.
Key HL7 FHIR Development Services
Healthcare organizations may require different interoperability capabilities. We can tailor development services around existing systems, workflows, and data exchange requirements.
FHIR API Development
FHIR APIs allow applications to exchange healthcare information using standardized resources. We design APIs around authentication, authorization, data validation, and interoperability requirements.
APIs can support applications such as patient portals, telehealth platforms, mobile health apps, and clinical dashboards.
FHIR Server Development
A FHIR server stores and exposes healthcare data through FHIR-compatible interfaces. We can develop or configure FHIR server environments based on application requirements.
The implementation can support resources such as Patient, Observation, Encounter, Medication, and Practitioner.
HL7 Integration Services
Many healthcare organizations still operate systems that use HL7 v2 messages. We can develop integration services that receive, process, transform, and route HL7 messages.
This approach can connect EHRs, laboratories, hospital systems, and other healthcare applications.
EHR Integration
Electronic health record, or EHR, integration allows applications to exchange information with clinical systems.
We can integrate compatible EHR environments through FHIR APIs, HL7 interfaces, or vendor-specific integration methods.
The integration strategy depends on the capabilities and documentation provided by each EHR vendor.
FHIR Data Mapping
Healthcare systems may represent the same information differently. Data mapping creates relationships between source data structures and FHIR resources.
We map relevant fields, values, identifiers, codes, and relationships according to the required implementation.
Healthcare Data Migration
Organizations may need to migrate data from legacy systems into modern healthcare platforms. We can transform legacy information into appropriate FHIR resources where applicable.
Migration processes should include validation, data quality checks, and reconciliation.
FHIR Testing and Validation
FHIR implementations require careful testing to verify that resources and APIs follow the expected specifications.
We can test resource structures, API responses, authentication, data validation, error handling, and interoperability workflows.
Common FHIR Resources
FHIR organizes healthcare information into standardized resources. Each resource represents a specific type of healthcare information.
Common resources include:
Patient
The Patient resource represents demographic and administrative information about an individual.
Practitioner
The Practitioner resource represents healthcare professionals who participate in healthcare activities.
Observation
Observation represents measurements and findings such as vital signs, laboratory results, and other clinical observations.
Encounter
Encounter represents interactions between patients and healthcare providers.
Medication
Medication represents information about medications used or managed within healthcare workflows.
Condition
Condition represents clinical conditions, diagnoses, or health concerns associated with a patient.
DiagnosticReport
DiagnosticReport can represent diagnostic results and reports from clinical investigations.
These resources can connect with each other to represent more complete clinical workflows.
HL7 FHIR Integration Use Cases
FHIR supports many healthcare applications and integration scenarios.
Patient Portals
Patient portals can use FHIR APIs to retrieve relevant healthcare information from connected systems. Patients may access appointments, medications, observations, and other authorized information.
Telehealth Platforms
Telehealth applications can integrate clinical information into virtual care workflows. Providers may access relevant patient data before or during remote consultations.
Remote Patient Monitoring
Remote patient monitoring platforms can transform device readings into appropriate healthcare data structures. FHIR resources can then help exchange this information with compatible clinical systems.
Healthcare Mobile Apps
Mobile applications can use FHIR APIs to exchange authorized patient information. This can support medication management, appointment tracking, health records, and other workflows.
Laboratory Integration
Healthcare platforms can connect laboratory systems with clinical applications. HL7 messaging and FHIR APIs can support the exchange of orders and results.
Pharmacy Integration
Pharmacy systems can exchange medication-related information with compatible healthcare platforms. The exact integration method depends on the systems involved.
Benefits of HL7 FHIR Development
Implementing FHIR can provide several benefits for healthcare organizations.
Improved Interoperability
FHIR provides a standardized approach for exchanging healthcare information. This can make it easier for compatible systems to communicate.
API-Based Integration
FHIR uses modern API patterns that support web and mobile applications. Developers can integrate healthcare information into different digital experiences.
Better Data Accessibility
FHIR-based integrations can make relevant information available to authorized applications. This can reduce dependence on isolated data repositories.
Reduced Manual Data Entry
Connected systems can exchange information automatically. This can reduce repetitive data entry across compatible workflows.
Support for Digital Health Applications
FHIR can support patient portals, mobile applications, telehealth platforms, analytics systems, and remote monitoring solutions.
Easier System Expansion
A well-designed interoperability layer can support additional integrations over time. Organizations can add compatible systems without redesigning the entire platform.
HL7 FHIR Security and Compliance
Healthcare interoperability involves sensitive patient information. Security should therefore remain a core part of every HL7 FHIR implementation.
Important controls can include:
Strong authentication
Role-based authorization
Encryption in transit and at rest
OAuth 2.0 and OpenID Connect
API access controls
Audit logging
Data validation
Secure token management
Monitoring and alerting
Vulnerability testing
FHIR implementations may use OAuth 2.0 and OpenID Connect for secure authorization and identity management.
Organizations handling protected health information should also evaluate applicable regulatory requirements. In the United States, this may include Health Insurance Portability and Accountability Act, or HIPAA, requirements.
Technical controls alone do not guarantee compliance. Organizations also need appropriate policies, procedures, contracts, and operational safeguards.
HL7 FHIR Development Process
A structured development process helps reduce interoperability risks and improves implementation quality.
1. Requirements Analysis
We identify source systems, target systems, data types, workflows, user roles, and integration requirements.
We also determine which HL7 and FHIR standards apply to the project.
2. Integration Architecture
We define the API architecture, integration layer, FHIR server requirements, authentication model, and data flow.
This stage helps establish how information will move between systems.
3. Data Mapping
We map existing healthcare data to appropriate FHIR resources and elements.
The mapping process should account for identifiers, terminology, codes, data types, and relationships.
4. API and Integration Development
We develop FHIR APIs, HL7 interfaces, transformation services, and integration workflows.
We implement validation and error handling to improve data quality and reliability.
5. Security Implementation
We configure authentication, authorization, encryption, auditing, and access controls based on the application's requirements.
6. Testing and Validation
We test resources, APIs, messages, integrations, and end-to-end workflows.
We also validate expected responses and error conditions.
7. Deployment and Monitoring
After testing, we deploy the integration environment and monitor system performance.
Monitoring can help identify API errors, message failures, authentication problems, and data inconsistencies.
8. Maintenance and Updates
Healthcare standards and connected systems can change over time. We maintain integrations and update implementations when requirements evolve.
