The connected health ecosystem is becoming increasingly important as technology continues to advance and healthcare systems become more complex. In 2023, the importance of a connected health ecosystem will propel multifold to support better remote monitoring, personalized care, improved efficiency, and better data analysis needs. There are several stats and trends supporting the connected health ecosystem model such as:


  • A study published in the Journal of Medical Internet Research found that remote patient monitoring resulted in a 44% reduction in hospital readmissions and a 38% reduction in emergency room visits for patients with chronic conditions.
  • A report by Accenture found that 60% of patients are willing to share their personal health data with healthcare providers if it results in personalized care.
  • A report by the Centers for Medicare & Medicaid Services (CMS) found that hospitals participating in the Hospital Value-Based Purchasing program had a 0.31% higher clinical process of care score when they used health information technology for quality measurement and reporting.
  • A study published in the Journal of Medical Internet Research found that using telemedicine for follow-up visits resulted in a 30% reduction in the time patients spent traveling to appointments and a 42% reduction in the time providers spent on each appointment.

To enable such a level of seamless, on-demand information exchange, healthcare providers, vendors, and developers are paying a great deal of attention to data standards. That’s where FHIR or Fast Healthcare Interoperability Resource has become a popular and widely adopted protocol. FHIR is an application-based approach for joining together disparate systems to enable interoperability and health information exchange. In this blog, we will discuss in detail what FHIR is, its importance in the connected healthcare ecosystem, and how it is being used to further health data exchange. And how FHIR transforms the health IT landscape as well. Let’s begin!

What is FHIR?

Fast Healthcare Interoperability Resources (FHIR) is a healthcare data exchange standard that is designed to make it easier for different healthcare information systems to exchange information with each other. FHIR is based on modern web technologies, such as HTTP and RESTful web services, and uses XML and JSON for data representation. It also standardized data elements, known as resources, to enable the sharing of healthcare information.

FHIR is designed to be flexible, easy to implement, and scalable, which makes it an ideal solution for healthcare providers, researchers, and developers who want to improve the interoperability of healthcare information systems.

Fast Healthcare Interoperability

Just like users worldwide can access the same URL and perform identical tasks using any standard browser on any web-enabled device, such as a smartphone, desktop, or tablet running on different operating systems like Windows, Apple, Android, or Linux, FHIR aims to achieve a similar goal. FHIR strives to enable developers to construct standardized “browser” applications that provide data access, regardless of the underlying EHR “operating system” that supports the user’s infrastructure. FHIR is becoming increasingly popular and is being widely adopted by the healthcare industry due to its ability to support better patient care, more efficient workflows, and improved outcomes.

Why Did The Healthcare Industry Need FHIR?

The healthcare industry has traditionally struggled with interoperability and data exchange between different systems, resulting in siloed data, inefficiencies, and increased healthcare costs. FHIR (Fast Healthcare Interoperability Resources) was developed to address these challenges by providing a modern, web-based standard for exchanging healthcare data electronically.

FHIR is designed to be simple, flexible, and scalable, allowing for the secure and efficient exchange of healthcare data across different systems and platforms. FHIR is also well-suited for use with mobile devices and web-based applications, making it easier for patients to access their health information and for healthcare providers to deliver care remotely. FHIR emerged as an integral tool for improving interoperability, reducing inefficiencies, and improving patient outcomes in the healthcare industry.

What Are The Benefits Of FHIR In The Healthcare Industry?

FHIR fosters healthcare data exchange to enable a better health ecosystem powered by the true potential of digitization. It provides several benefits to payers and providers, such as:

Interoperability of data

There was a dire need to facilitate the interoperability of health data as it allows different healthcare systems to exchange patient data securely and efficiently. FHIR here enables different healthcare systems and devices to communicate with each other, regardless of the platform or vendor.

This improves the exchange of patient data, leading to better diagnoses and treatment plans, ultimately leading to improved patient care and outcomes. When healthcare systems are interoperable, doctors, nurses, and other healthcare professionals can access patient data from multiple sources, such as EHRs, medical devices, and other systems, regardless of where the data is located.


FHIR brings standardization to healthcare data exchange by defining a set of standardized resources and data elements that can be used to represent healthcare information. This enables different healthcare systems to communicate with each other using a common set of data elements, which facilitates data exchange and promotes interoperability.

FHIR also defines a set of standard APIs for accessing and manipulating healthcare data, which makes it easier for developers to create applications and services that can be used across different healthcare systems.


FHIR enables faster and more efficient data exchange, which can save time and reduce costs for healthcare providers. It enables faster and more efficient data exchange by using modern web technologies and standard data formats. FHIR uses RESTful APIs that allow for easy and flexible communication between healthcare systems, devices, and applications.

These APIs are based on widely-used web standards like HTTP, JSON, and XML, which make them easier to understand and use. This is especially important for providers who need to access patient data quickly in emergency situations.

Patient-Centered Care

FHIR enables healthcare providers to access a patient’s complete health history, including data from other providers and healthcare systems. This can help providers make more informed decisions about patient care and provide more personalized treatment plans. FHIR’s focus on patient-centric data modeling enables the representation of health information in a way that is easy for patients to understand and access.

Additionally, FHIR includes specific resources and elements for representing patient preferences and goals of care, which allows for more personalized and patient-centered care planning. FHIR also enables patients to have greater control over their own health data through standardized access and authorization mechanisms, which allows patients to share their data with providers and caregivers as needed.


FHIR provides a flexible and scalable platform for healthcare data exchange, which can enable innovation in healthcare delivery and the development of new applications and services. Developers can quickly and easily build new applications and services on top of FHIR, leveraging standardized data and APIs to provide new and innovative solutions for healthcare data exchange and management.

This flexible and scalable platform provided by FHIR supports ongoing innovation in the healthcare industry and helps to improve the quality and efficiency of healthcare delivery.


FHIR is compliant with healthcare data privacy and security regulations, ensuring the protection of patient data. Besides supporting interoperability between different healthcare systems, FHIR supports role-based access control, data encryption, consent management, secure transport protocols (protect data during transmission between systems), audit trails, and complaint management, including HIPAA and GDPR. This way, it secures healthcare data transmission electronically just like other industries ensure security for data exchange.

How Is FHIR Related To EHR?

FHIR and EHR are both related to healthcare data exchange and management, but they serve different purposes and have different scopes. FHIR, or Fast Healthcare Interoperability Resources, is a standard for exchanging healthcare data between systems, applications, and devices. It provides a set of resources, APIs, and profiles that enable data exchange in a standard and interoperable way. FHIR is focused on data exchange and interoperability, rather than data storage and management.

On the other hand, EHR, or Electronic Health Record, is a digital record of patient health information that is collected, managed, and accessed by healthcare providers. It contains a patient’s medical history, diagnoses, medications, lab results, and other healthcare data.

EHRs are designed to provide a comprehensive view of a patient’s health information across different care settings and providers. FHIR is used as a standard for exchanging healthcare data, while EHR is a system for collecting, managing, and accessing patient health information. While FHIR can be used to facilitate EHR data exchange, they are different concepts with different purposes and scopes.

How Does FHIR Work?

FHIR (Fast Healthcare Interoperability Resources) works by providing a standardized format for exchanging healthcare data electronically. Here’s how it works:

FHIR Resources

FHIR defines a set of standardized resources, which represent discrete pieces of healthcare data, such as patient demographics, clinical observations, and medications. These resources are defined using a consistent data model and are designed to be easily understood by both humans and machines.


FHIR uses a RESTful API (Application Programming Interface) to enable communication between different healthcare systems and devices. RESTful APIs use standard HTTP requests to send and receive data, making them simple and easy to use.

Data Exchange

Using FHIR, healthcare providers can exchange patient data securely and efficiently across different systems and platforms. For example, a healthcare provider using an EHR system could use FHIR to access patient data from another healthcare provider’s system, such as a lab result or imaging study.

Implementation Guides

FHIR also provides implementation guides, which are detailed instructions on how to use FHIR to exchange specific types of healthcare data. These guides help ensure consistency and standardization in the use of FHIR across different healthcare systems and organizations.
