With health going digital, FHIR has emerged as the gold standard for moving data from one place to another. Developed by Health Level Seven International (HL7), Fast Healthcare Interoperability Resources (FHIR) facilitates seamless communication between disparate systems. Beyond just handling health records, FHIR in healthcare acts as a bridge for everything from lab systems to wearable medical devices. This expansion addresses critical needs in modern healthcare, like real-time data sharing and improved patient outcomes.
According to HL7 and ONC-aligned industry data, a large majority of U.S. hospitals now support FHIR-based APIs within their EHR systems, but the real innovation lies in how FHIR is being applied beyond traditional clinical records. Therefore, we’ll explore how FHIR bridges the gap between different tech, like heart monitors and lab software, to help everything run smoothly.

Understanding the Foundations of FHIR in Healthcare
FHIR in healthcare builds on a resource-oriented architecture. Each resource represents a specific data element, like a patient’s demographics or a diagnostic test result. These resources can be queried, created, updated, or deleted via standard HTTP methods, similar to how web services operate. This approach contrasts with rigid, message-based standards of the past.
For example, by using the Observation resource to log blood pressure or glucose, you can share critical health data with a whole range of platforms outside the EHR. FHIR relies on this foundation to stop data from getting trapped in separate silos. The U.S. Core FHIR profiles, mandated by the Office of the National Coordinator for Health Information Technology (ONC), set baselines for interoperability in the United States.
FHIR in Healthcare Device Integration: Connecting Wearables and IoT
One of the most transformative applications of FHIR in healthcare involves medical devices. From wearable fitness trackers to implanted pacemakers, devices generate vast amounts of data. FHIR uses the Device resource to describe the equipment, DeviceMetric to track how it’s performing, and Observation to tie it all to the patient’s actual results.
Consider smartwatches like the Apple Watch. These devices continuously capture heart rate, activity, sleep, and ECG data. With FHIR APIs, this patient-generated information can flow directly into healthcare systems. For example, users can share their stats with providers via Apple’s HealthKit, thanks to its built-in support for FHIR export. As a result, clinicians can view Apple Watch data inside EHRs or through connected applications, supporting remote monitoring of chronic conditions and earlier clinical interventions.
Within hospitals, FHIR in healthcare also supports IoT device integration. Ventilators, infusion pumps, and bedside monitors share data via FHIR gateways, with IHE FHIR profiles providing standardized device communication. This shift toward FHIR-enabled device connectivity transforms isolated equipment into part of a unified clinical ecosystem.
Moreover, FHIR supports real-time streaming. Using WebSockets or subscriptions, devices can push updates instantly. This capability proves critical in intensive care units, where delays in data can impact decisions. Standards like IEEE 11073, when mapped to FHIR, bridge legacy devices to modern networks.
Integrating Labs with FHIR in Healthcare: Streamlining Diagnostic Data
Laboratory information systems (LIS) manage a wide range of test results, from common blood work to specialized genomic assays. FHIR in healthcare provides standardized resources such as DiagnosticReport and Observation that represent lab results and associated data in structured form, making it possible to share results, interpretations, and specimen information across systems in a consistent way.
Traditional lab integrations relied on HL7 v2 messages, which often required custom mappings. FHIR replaces the custom mappings of HL7 v2 with a RESTful API to request and retrieve specific resources (e.g., using GET operations for Observation or DiagnosticReport) through standardized REST endpoints.
API platforms that support FHIR profiles — such as third-party diagnostic networks that exchange orders and results with major labs — illustrate how modern interoperability frameworks can integrate laboratory data into broader clinical workflows.
There are also dedicated implementation guides, including the HL7 FHIR Genomics Reporting Implementation Guide, which define conventions for reporting genomic test results in structured FHIR formats.
By providing uniform data models and API mechanisms, FHIR enables more flexible querying of lab results, improved electronic exchange with EHRs and downstream systems, and the potential for faster availability of diagnostic information in clinical decision-making processes.
FHIR in Healthcare Remote Monitoring: Supporting Telehealth and RPM
Remote Patient Monitoring (RPM) systems collect health data from patients outside traditional clinical environments using connected devices. FHIR resources like Observation capture readings from home-based devices, while CarePlan, Goal, and ServiceRequest can represent monitoring protocols, clinical objectives, and follow-up actions. This structured approach enables RPM data to be integrated into electronic health records and care management platforms in a consistent, interoperable format.
Major digital health and medical technology companies, including Philips and Medtronic, support interoperability standards such as HL7 and FHIR across their connected care and digital health platforms.
FHIR also supports real-time event notifications through subscription mechanisms. Instead of constantly checking for updates, FHIR pings connected systems in real-time whenever new data or specific triggers occur. This capability enables proactive care models, such as alerting care teams when a patient’s blood glucose, oxygen saturation, or blood pressure readings indicate potential deterioration.
In mental and behavioral health, FHIR-enabled applications can exchange structured data such as mood assessments, questionnaires, wearable-derived activity metrics, and therapy notes, supporting more integrated digital care experiences across platforms.
In the United States, the Centers for Medicare & Medicaid Services (CMS) provides reimbursement pathways for RPM services and promotes the use of standardized APIs for data sharing. While FHIR is not mandated for RPM reimbursement, it is widely adopted as a practical standard for meeting interoperability requirements.
