FHIR facades are a powerful tool for simplifying and accelerating FHIR development. They can abstract away the complexity of FHIR healthcare standard and provide a more user-friendly interface.
FHIR facades are particularly useful for organizations that need to integrate FHIR with legacy systems or that want to develop FHIR applications without becoming experts in the FHIR standard. By using the FHIR facade, organizations can avoid developing their own FHIR server and instead focus on developing their FHIR applications.
In this article, you will learn everything you need to know about FHIR facades, including what they are and how they work, why and when to use them, their benefits and challenges, and best practices for using them. You will also learn how Binariks can help you implement an FHIR facade.
Whether you are an FHIR developer, a healthcare organization looking for FHIR implementation , or simply curious about FHIR, this article is for you. Let's start from the very beginning!
What is an FHIR facade?
An FHIR facade is a software layer between an FHIR client application and a backend system, such as a database or a legacy healthcare system. It acts as a translator, converting data between the FHIR format and the format used by the backend system. This allows FHIR applications to interact with the backend system without understanding its proprietary format, thus streamlining FHIR development.
Key components of an FHIR facade:
- Mapping engine: Converts data between FHIR and the backend format.
- Security layer: Ensures that only authorized users can access the backend system.
- Logging and auditing: Tracks all interactions with the backend system.
- Error handling: Handles any errors that occur during data conversion or communication.
How an FHIR facade works:
When an FHIR application requests the FHIR facade, it translates the request into the FHIR format and forwards it to the FHIR server. The FHIR server processes the request and returns a response to the FHIR facade. The FHIR facade translates the response back into the format expected by the FHIR application and returns the response back to it.
Why and when to use an FHIR facade?
You should consider using an FHIR facade if:
- You are developing an FHIR application that needs to interact with a legacy system.
FHIR facades can be used to bridge the gap between FHIR and legacy systems, which typically use different data formats and communication protocols. This can save developers time and effort, as they do not need to develop their custom integration code.
- You are developing an FHIR application that needs to interact with a backend system that does not support FHIR natively.
FHIR facade usage helps translate data between FHIR and the backend format, allowing FHIR applications to interact with any backend system, regardless of its native data format.
- You want to simplify the development and maintenance of your FHIR applications.
FHIR facades can abstract away the complexity of FHIR, making it easier for developers to build and maintain FHIR applications. FHIR facades can also centralize the management of FHIR interactions, which can reduce the amount of code developers need to write and maintain.
- You want to ensure interoperability between your FHIR applications and other systems.
FHIR facades can help to ensure interoperability between FHIR applications and other systems by translating data between FHIR and the format used by the other system. This can help improve the communication and integration between different healthcare systems.
- You want to reduce the cost of FHIR development and deployment.
FHIR facade implementation helps reduce the cost of FHIR development and deployment by centralizing the management of FHIR interactions and abstracting away the complexity of FHIR. This can free up developers to focus on building FHIR applications rather than developing and maintaining custom integration code.
- You want to improve the scalability and security of your FHIR applications.
FHIR facades can help to improve the scalability and security of FHIR applications by decoupling the FHIR application from the backend system. This allows FHIR applications to scale independently of the backend system and makes it easier to implement security measures for FHIR applications.
The FHIR facade pattern offers many advantages over traditional approaches to FHIR development. Here are a few crucial ones to keep an eye on:
- Increased agility: FHIR facades can help organizations become more agile by making it easier to develop and deploy new FHIR applications.
- Reduced risk: FHIR facades can help reduce the risk associated with FHIR development by providing a proven and tested framework for FHIR integration.
- Improved compliance: FHIR facades can help organizations comply with FHIR standards and regulations by providing a robust and scalable FHIR implementation.
- Accelerated time to market: FHIR facades can help organizations accelerate the time to market (TTM) for their FHIR applications by simplifying and streamlining the development process.
If you are unsure whether or not you need to build an FHIR facade, consulting with an experienced FHIR developer or architect is always a good idea. They can help you to assess your specific needs and to determine the best approach for your organization.

Choosing the right FHIR facade
When choosing an FHIR facade, there are several factors to consider:
- Features: Different FHIR facades offer different features and functionality. It is important to choose an FHIR facade that provides the features that your organization needs. For example, some FHIR facades support multiple FHIR versions, while others do not. Some FHIR facades also support additional features, such as security and authorization.
- Performance: FHIR facades can vary significantly in terms of performance. an FHIR facade must be able to handle the expected load of your organization's FHIR applications.
- Scalability: As your organization's FHIR needs to grow, you need to be able to scale your FHIR facade accordingly. Choose an FHIR facade that can be scaled to meet your future needs.
- Support: It is essential to choose an FHIR facade supported by a reputable vendor. This will ensure you get help and necessary updates when you need them.
Now, let's talk about repositories. an FHIR repository is a database that stores FHIR resources. It is typically used by FHIR applications to store and retrieve FHIR data. FHIR repositories can be used with or without an FHIR facade, but which is right for you?
Well, there are a lot of FHIR use cases , and whether you need an FHIR facade or an FHIR repository depends on your specific needs. If you need to integrate an FHIR application with a legacy system or a back-end system that does not support FHIR natively, then you need an FHIR facade. If you need to store and retrieve FHIR data, then you need an FHIR repository.
In some cases, you may need both an FHIR facade and an FHIR repository. For example, you may need an FHIR facade to integrate an FHIR application with a legacy system and an FHIR repository to store and retrieve the FHIR data exchanged between the two systems.
Best practices for using an FHIR facade
An FHIR facade can be a powerful tool for simplifying and accelerating FHIR development. Talking about HL7 vs FHIR , we can say that FHIR is a newer standard, and it is designed to be more flexible and extensible.
