Origin and Evolution of the Concept of FHIR

As with every industry, healthcare primarily provides high-quality care to patients at the right time. This requires timely access to and exchange of accurate health data. An ever-growing amount of healthcare data, the rise of “online culture”, and heavy reliance on digital technology have made adopting modern technologies necessary in healthcare. Enter the need for a standardized, secure, quick, and easy data exchange between various healthcare information systems, databases, applications, and software used across the healthcare industry.

Regulatory initiatives in the United States have played a crucial role in advancing healthcare interoperability. The journey commenced in 2019 with the initiation of Federal Interoperability Efforts dedicated to fostering and executing interoperability. A pivotal government initiative, the draft of the Trusted Exchange Framework and Common Agreement (TEFCA) surfaced in 2018. Subsequently, 2019 marked the initiation of collaborative efforts with various regulations, witnessing annual advancements in interoperability.

A breakthrough occurred in 2021 when every ONC-certified Electronic Health Record (EHR) system in the US was mandated to implement Fast Healthcare Interoperability Resources (FHIR). This requirement represented a significant stride in interoperability, laying the foundation for the current state of affairs.

What is FHIR?

According to the HL7 website, “The philosophy behind FHIR is to build a base set of resources that, either by themselves or when combined, satisfy the majority of common use cases. FHIR resources aim to define the information contents and structure for the core information set shared by most implementations.”

Interoperability and standardization lie at the heart of FHIR (Fast Healthcare Interoperability Resources). Created by the HL7, a non-profit standards development organization that focuses on the interoperability of health information technology, FHIR is a standard that defines how healthcare information is stored and exchanged electronically. FHIR data models use modern web technologies to facilitate easy and timely access to core clinical and administrative data.

Why Does the Healthcare Industry Need Interoperability?

What Does FHIR Address?


So why is FHIR such a big deal for the healthcare industry? This is because, sadly, outdated systems such as email or fax machines and document-based records still act as barriers to seamless health data exchange and access. These legacy systems create data silos, making it difficult for healthcare providers to access patient data with full context, such as patient history and previous records.

The diverse and disconnected data sets or systems that store healthcare information lack standardization. Disparate data sources often use different formats, standards, or data models, making it challenging for systems to understand and interpret information consistently. This lack of interoperability hinders seamless data exchange between different healthcare applications and systems.

Healthcare IT systems such as EHRs are used extensively in different healthcare organizations. However, these systems face challenges when it comes to seamlessly exchanging data with external systems such as laboratories, imaging systems, pharmacies, and other healthcare providers.

Timely access to accurate patient data is crucial in healthcare, especially in situations of emergency or urgent care. FHIR supports real-time data exchange, which allows healthcare providers to access the most recent information when it is needed the most.

How Does FHIR Facilitate Interoperability?

Interoperability is about prioritizing and sharing the patient’s complete story. FHIR makes the shift to patient-centric healthcare possible by ensuring that patients and healthcare providers get accurate information from health IT systems. Through FHIR, different computer systems can easily exchange updated clinical and administrative data for the well-being of a patient receiving medical care.

The quest for organizing and securely storing healthcare data initiated the development of FHIR around 2011, and it was officially released as a draft standard in 2014. FHIR defines a set of standardized data elements known as resources or data models.

Each resource has a tag that acts as a unique identifier, just like the URL of a web page. These resources represent different types of core healthcare data, such as information about patients, providers, observations, medications, care plans, and more. About 150 of these are listed in the FHIR guidelines. The use of these standardized resources allows for consistent representation and interpretation of data across diverse healthcare systems.

With FHIR, the goal was to create a standard that leverages modern web technologies like RESTful APIs (Representational State Transfer Application Programming Interfaces). RESTful APIs make it easier for different systems to communicate and share healthcare data over standard HTTP protocols. Since these web standards are widely used and familiar outside of the healthcare industry, software developers can easily implement these standards without prior experience in healthcare IT.
