  • FHIR is a standardized protocol that enables the exchange of healthcare data across different healthcare systems.
  • With Epic FHIR integration, Epic's EHR can communicate with other systems, such as electronic medical record (EMR) systems, and exchange patient information efficiently.
  • FHIR endpoints provide a standardized way for these systems to interact, allowing for the secure exchange of patient data, including clinical records, encounter diagnoses, laboratory results, and medication information.
  • This integration enhances interoperability.

Leverage FHIR Endpoints for Secure Patient Data

When talking about software and technology applications, the term integration often comes up in retail, wholesale, and health-related businesses.

Integrations drive automation and customer self-service applications but can present special challenges for health practices because of demanding HIPAA regulations for privacy, security, and utility.

Fortunately, these problems can be resolved with an Epic EHR-EMR integration with FHIR endpoints.

FHIR works better across siloed medical systems because it communicates more effectively in today's digital environment.

Built on JSON for structured content, RESTful APIs, and other common codes and formatting standards, the FHIR standard is both future-proof and easy to connect to existing systems to provide meaningful use in patient portals.

What Is Epic/FHIR Endpoint Integration?

Medical practices face the twin challenges of providing greater patient access while ensuring HIPAA-level security.

FHIR is an API format with predefined endpoints. The API layer is outside the HIPAA-compliant website's firewalls, so all incoming and outgoing data can be verified for validity and security before being accepted into the system.

The robust nature of Epic's EHR and EMR technology when combined with FHIR endpoints makes it easy for developers to integrate medical apps, health monitoring devices, patient portals, medical mobile apps, and third-party resources into their systems.

The technical details of an FHIR Epic integration can be challenging for any medical practice because healthcare staff members usually work on medical issues instead of development and security technology.

That's why it's important to hire an experienced software development company to implement an EMR-EHR system and handle the secure EMR integration.

SMART on FHIR and HL7 are two kinds of integration technologies that protect and transport healthcare data

FHIR and HL7 Details

FHIR provides a robust API environment for secure access to HL7 patient data.

HL7 creates the actual specifications, and FHIR and SMART EHR are guidelines used to implement the technology.

The internal systems of hospitals, clinics, and other health practices need to install, configure, and update their internal operating systems to incorporate these standards.

That's why medical companies need an experienced and trusted developer for a seamless integration process of an Epic instance and FHIR with their health system.

What About SMART on FHIR?

SMART on FHIR is a healthcare technology standard that integrates the Fast Healthcare Interoperability Resources (FHIR) protocol with SMART (Substitutable Medical Applications, Reusable Technologies) to enable interoperability and data exchange in healthcare applications. It facilitates the development of modular and interoperable health apps that can run seamlessly across different healthcare systems.

The SMART on FHIR framework ensures that applications can access and interact with electronic health records (EHRs) while maintaining security and privacy standards. This standard leverages modern web technologies, such as OAuth 2.0, to enable secure authorization and authentication, allowing healthcare providers and patients to benefit from a diverse ecosystem of applications that enhance patient care, research, and overall healthcare delivery.

SMART on FHIR promotes innovation and collaboration within the healthcare industry by providing a standardized approach to building and deploying healthcare applications.

Benefits of EHR-EMR Integration with FHIR Endpoints

EHR integration services of HIPAA-approved technologies foster greater communication between patients and staff, streamline office operations, and enable more self-service functions for patients.

Practices can meet their targets for the Medicare and Medicaid patient meaningful use mandate to qualify for government reimbursement. The more that patients use and consult their electronic health records and other medical history files, the better their treatment will be.

Some of the benefits of using FHIR endpoints and integration with Epic for staff and patients include [1]:

Ease of Communications

Staff can post critical information to patients in a secure forum.

The Diagnostic Report Application

Patients can link to verified outside information associated with lab procedures.

The Observation Resource

The observation resource enables analyses of vital signs, encounter diagnosis, smoking history, bad health habits, and lab results to identify common health problems. Patients can consult expert resources for further information.

Health Provider Care Plan Details

Each patient can receive specific assessments and treatments for associated medical, surgical, dental, and diagnostic procedures.

Appointment Management

All appointments are listed on secure patient portals that patients can consult anytime.

Overcoming Common System Limitations

The FHIR standard overcomes many limitations by making it easier to incorporate proprietary health apps and health information into EHR/EMR systems and allowing greater interoperability for software companies and FHIR app developers to create better features and apps for patients [2].

Bill Management

Patients can pay their bills and view their medical invoices 24/7. That increases on-time payments and reduces no-pays.

FHIR endpoints enable patients, doctors, pharmacies, and insurance companies to exchange data without the rigid workflows of other methods. There's no need for SOAP overhead when the system can use a straightforward RESTful approach. FHIR enables medical practices to focus on the 80 percent of common uses instead of the rarefied 20 percent of exceptions [3].

NEST Technology

NEST technology is the government's initiative to create universal interoperability among medical databases.

Spearheaded by the FDA, the goal of the initiative is to foster increased safety for medical-related devices and better input from devices, monitoring services, health providers, registries, patients, payers, insurers, and manufacturers to create a collaborative workspace where every stakeholder can work together on each patient's health [4]. FHIR technology is one of the most promising standards for building a universal interoperable platform.

FHIR are standardized data formats used in healthcare to exchange patient records—often in the form of electronic health records (EHRs)—and other healthcare information. They serve as building blocks for health information exchange, allowing data exchange between different systems and providers.

FHIR resources represent discrete pieces of health information, like patient demographics, medications, or diagnoses. These resources are structured in a standardized way, enabling easy integration with various healthcare applications. FHIR promotes interoperability with its data sharing, making it simpler for different health systems to communicate and share information, ultimately improving patient care, research, and healthcare system efficiency.


Epic EHR-EMR integration with FHIR endpoints is crucial for several reasons. First, it enhances interoperability by enabling the seamless data exchange between Epic's EHR system and external electronic medical record (EMR) systems. This promotes care coordination and ensures care providers have access to comprehensive patient data from every point of the health system. This information sharing can be enhanced during healthcare software development or integration.

Second, the integration streamlines workflows, eliminating the need for manual data entry and reducing errors. It also facilitates the integration of third-party healthcare apps and systems, allowing for the utilization of innovative tools and technologies to improve patient care after the encounter diagnosis.


FHIR endpoints, in the context of health records, refer to the specific URLs or web addresses where FHIR APIs are exposed by health systems or EHR platforms. These endpoints act as communication channels through which different systems can interact and exchange health record data using FHIR standards.

FHIR endpoints enable authorized applications or services to query, retrieve, update, and transmit health information securely. They provide a standardized and structured approach to accessing health record data, allowing for interoperability and integration between various care systems, applications, and devices, ultimately allowing it to exchange data and improve collaboration in the healthcare ecosystem.


Epic/FHIR endpoints enable it to exchange data to facilitate interoperability and seamless integration between Epic's EHR system and external systems. These endpoints allow for the secure exchange of patient-centric data between and within healthcare organizations, including patient demographics, clinical observations, diagnostic reports, medications, procedures, allergies, immunizations, vital signs, care plans, and more.

Additionally, FHIR endpoints enable the transmission of administrative data such as appointments, admissions, discharges, and transfers. The use of FHIR standards ensures that these data exchange elements are structured and standardized, allowing for consistent interpretation and seamless sharing of information between different health systems, health information exchanges, applications, and providers.


Epic integration with FHIR endpoints offers several benefits for healthcare providers, including:

  1. Enhanced care coordination: Providers can access and share up-to-date basic patient information from multiple sources, improving care coordination and clinical decision-making within healthcare organization systems.
  2. Reduced data entry: Epic integration eliminates the need for manual data entry across different systems, saving time and reducing the risk of errors.
  3. Comprehensive patient view: By pulling data from various sources, Epic integrations present a more comprehensive view of the patient's health history, enabling better-informed treatment decisions.
  4. Interoperability: FHIR-based integration allows seamless data exchange with other systems, promoting interoperability and avoiding data silos.

The United States Core Data for Interoperability (USCDI) is a standardized set of healthcare data elements defined by the U.S. government to promote interoperability and patient data exchange across care systems. USCDI specifies a common set of health data elements, such as patient demographics, clinical observations, diagnostic reports, medications, and procedures, that should be made available for exchange between different healthcare organizations.

It serves as a foundation for the adoption and implementation of health information technology systems, ensuring that essential data can be easily shared and accessed across various care settings. USCDI and Epic FHIR resources facilitate improved care coordination, patient engagement, and overall healthcare quality by enabling the secure exchange of standardized health information.
