The Most Common Approaches of FHIR Implementation

Fast Healthcare Interoperability Resources (FHIR) is a flexible framework that offers multiple implementation options tailored to the distinct requirements of healthcare organizations. The four most common approaches to FHIR implementation are: 

1. FHIR RESTful API Implementation

In a RESTful API implementation, FHIR leverages web standards to create, read, update, and delete (CRUD) operations on resources. This approach is particularly valuable in real-time applications where healthcare systems need to interact dynamically. It’s a straightforward method where resources are treated as URLs, and standard HTTP verbs are used. RESTful API implementation is popular because of its simplicity, scalability, and compatibility with modern web architectures.

2. FHIR Messaging Implementation

In the messaging implementation, FHIR resources are used within existing HL7 message structures. This allows healthcare systems to take advantage of FHIR’s granularity and flexibility while retaining their investment in HL7 messaging infrastructure. It’s an event-driven model, where a trigger event in one system leads to a message being sent to another system. This approach is suitable for batch-style and background processing tasks.

3. FHIR Document-Based Implementation

In the document-based implementation, FHIR resources are bundled together to create self-contained, discrete units of healthcare information called documents. This is a particularly effective way to handle complex use cases that involve multiple resources, such as a discharge summary or a referral note. These documents can then be readily shared, stored, and retrieved, making them ideal for interoperability purposes.

4. FHIR Hybrid Implementation

As the name suggests, hybrid implementation combines various approaches based on the healthcare system’s needs. For example, a healthcare provider could leverage a RESTful API to facilitate real-time interactions, utilize messaging for batch processing tasks, and employ document-based approaches for handling complex FHIR use cases. This flexible approach ensures that healthcare systems can leverage FHIR’s strengths in a way that best suits their operational needs and strategic goals.

Choosing the right approach for FHIR implementation requires a careful understanding of the healthcare system’s requirements, existing infrastructure, and strategic goals. With the right approach, FHIR can significantly enhance healthcare data interoperability, leading to improved patient care and operational efficiency.
