Everything you need to know about FHIR

There has always been a persistent move towards digitalization of all (or at least most) medical records so as to facilitate data exchange and improve patient outcomes.

In order for patients to navigate the healthcare system effectively, their data needs to be easily accessible and understood by users in terms of the available digital tool.

Additionally, such data should follow the set standard so that it can be easily integrated into automation systems and processes. With the fast healthcare interoperability resources (FHIR), the entire healthcare community feels they have made significant progress in digitalizing global patient data.

If you work in the healthcare business, you may already be familiar with FHIR and HL7, primarily since CMS's new standardization regulations were implemented in the past years. 

For many, these are still hazy concepts—difficult-to-define letters tied to EHR (Electronic Health Record) and the always-frightening threat of heightened regulatory compliance. But have no worries.

Knowing the distinction between HL7 and FHIR might be crucial for your company in the following months and years. With that in mind, here's the relationship between FHIR and HL7: what they are, how they vary, and why it matters for your organization.

HL7 and FHIR are both healthcare data standards for exchange but have different characteristics. One major difference between the two is the fact that FHIR uses RESTful web services and web open standards such as XML, JSON, and RDF, whereas HL7 does not have any such capabilities and only provides support for XML. The use of web open standards allows FHIR to be more lightweight and flexible so that it can send smaller and discrete data packets as compared to HL7 which only deals with larger messages.

The ability of FHIR to use RESTful services makes application development simpler by being able to use healthcare data exchange more granularly and modularly.

The other major distinction between FHIR and HL7 is their data model. HL7 employs a more rigid data modeling technique, which makes adding new data items difficult depending on the situation. Conversely, FHIR employs a more flexible data modeling method, allowing it to create new data items where necessary. FHIR's flexibility thus allows it to be better adapted to changes in the healthcare industry.

FHIR's use of open web technologies and flexible data models makes it a more versatile standard than HL7. It stands to reason that FHIR will become an increasingly important standard for healthcare data exchange.

HL7 FHIR Standard is a breakthrough health care interoperability system that is freely accessible and has no constraints whatsoever.

• A strong focus on ease of implementation. What does it mean? It implies that it was intended to be simple to implement in order to serve as an effective way to optimize processes in health care organizations.
• Data standardization during healthcare communication. Thanks to this standardized system, mistakes have been avoided while exchanging health care data, improving its overall quality.
• A modular and scalable approach to data modeling. This way to model information provides more opportunities to extend data elements and resources. As such, FHIR is a scalable solution that adapts well to changes in the health care environment, thus being highly customizable.
• The ability to coexist with and take advantage of prior standards. Such as HL7 Version 2 and CDA. This interoperability helps ensure that FHIR is able to easily incorporate prior systems, thus making the process more efficient.
• Interoperability "out of the box." In other words, it was designed from the outset to interact with other systems and technology. This has helped healthcare facilities communicate and exchange information.

Interoperability is essential in healthcare because it allows different systems and devices to communicate, enabling healthcare providers to access all relevant patient information in one place. 

Access to relevant healthcare data, regardless of location, dramatically benefits patients, doctors, healthcare providers, funders, governments, and society.

Yet there is an issue. Extensive healthcare IT platforms have sprung up worldwide without the capacity to interchange data quickly. 

Vital patient information is kept in 'data silos,' and older systems still employ emails and faxes to send records, files, and results. Physicians can only treat patients with complete histories, and researchers cannot obtain de-identified data.

FHIR is crucial because it simplifies the process of exchanging healthcare information, making it easier to achieve interoperability.

The benefits of FHIR interoperability are ample, including improved patient care and coordination, reduced costs, and better efficiency.

FHIR enables the transition from hospital-centric to patient-centric collaborative healthcare, allowing physicians and patients to gain what they need from health IT systems.

Patients can connect with several physicians in various places and healthcare settings while maintaining a single personal health record with a complete history of all their prescriptions, concerns, allergies, and consultations.

Overall, FHIR interoperability is an invaluable asset for advancing the healthcare industry in terms of both functionality and patient outcomes.

A patient who visits their doctor frequently has to supply health information. Despite this, they've most likely filled out the same form several times before. Instead, individuals may arrive in an emergency, unable to answer critical inquiries regarding their current diseases or sensitivities.

FHIR contributes to the safe availability of clinical and administrative information by guaranteeing that different computer systems may 'speak' to one other in different places. It is built using the same technologies that run the internet, so it is quick, simple to use, and well-accepted by the developer community.

FHIR apps can connect directly with FHIR-enabled servers, much as internet users anywhere on the planet may access the same URL.

• Interoperability is quick and straightforward.

• Web-based data exchange.

• Specifications that are easy to use and concise.

• Tools and procedures that are well-known.

• Major vendor assistance.

• There are several free internet tools and open-source libraries available.

• A global, lively community is driving the standard.

• It is suitable for a wide range of applications.

• Resource summaries that are comprehensible by humans.

FHIR uses the standard technology including XML, JSON, HTTP, OAuth, GraphQL, and REST, making it easier to integrate into existing technologies.

In addition to that, FHIR is an open-source standard. This implies that it does not cost any money to use. It represents an affordable technology for healthcare providers and developers that cannot afford proprietary software and standards.

The FHIR framework makes use of a modular approach for the sharing of healthcare data, whereby each item of data is described as "a resource."

The resources can be joined to form the full patient profile, which can seamlessly share information between different healthcare systems and applications.

To find the history for any resource or version, certain methods are used to enhance interoperability. This specification is provided on the internet, where it is hyperlinked and linked to the resource of the property through data types.

There are three parts that make up FHIR – general documentation, implementation, and the resource list. Documentation available provides information on how the resources are modeled, including definitions of data types and codes and formats like XML and JSON. Users can access RESTful programming interface resource for their own usage as clinical papers and service-oriented architecture.

FHIR offers a framework for extending and altering resources so that any system may read them, regardless of how they were created. Extension definitions can be fetched using the exact mechanism as other resources. Each resource may include a human-readable text representation in HTML.

FHIR's concepts for enabling interoperability through well-structured data models include the following:

• Reuse: To prevent an overcomplicated and duplicate resource collection, FHIR resources are designed to fulfill the broad demands of health care.

• Performance: Compared to prior standards, FHIR resources are more straightforward in their architecture, making them more suited for network exchange and more accessible for developers to understand and use.

• Usability: FHIR resources are intended to be understood by both technical professionals and non-technical users.

• Fidelity: Intermixing values of different data kinds, such as strings and numeric values, is strictly prohibited in FHIR resources. In addition to established sets of business rules, they can be validated by their syntax.

• Implementability: FHIR's main objective was to build a standard that various development groups would widely adopt.

FHIR resources are designed to be easy to comprehend and exchange using industry standards, commonly used programming languages, and well-tested techniques for exchanging information.

The FHIR profile, by contrast, is the way resources are supposed to be used in some context; this could be an organization or a program that uses FHIR resources. It imposes restrictions and extensions on how a resource may be used. This helps ensure consistent and accurate exchange of information between systems and programs.

Profiles can be used to tailor the specification to meet the requirements of an individual organization or program.

In today's healthcare landscape, interoperability is critical to delivering quality patient care. FHIR (fast healthcare interoperability resources) is an emerging standard gaining popularity in exchanging healthcare data between disparate systems. Many well-known organizations already use FHIR to improve data exchange and streamline care coordination.

One such organization is Epic Systems, a leading electronic health record (EHR) vendor that supports FHIR to exchange healthcare data between different EHR systems. Similarly, Cerner Corporation, another major EHR vendor, recognizes the value of FHIR for healthcare data exchange.

Tech giants Apple and Google are also on board with FHIR. Apple's Health app supports FHIR for exchanging healthcare data between different health apps and systems. Meanwhile, Google's Cloud Healthcare API supports FHIR to exchange healthcare data between other healthcare systems.

Microsoft has also developed its FHIR-based solution. The Azure API for FHIR allows developers to build healthcare applications that can exchange data using the FHIR standard.

Government agencies also recognize the benefits of FHIR. The Centers for Medicare and Medicaid Services (CMS) use FHIR to support healthcare data exchange for quality reporting and other purposes. The Veterans Health Administration (VHA) also uses FHIR to support healthcare data exchange between different VHA systems and external partners.

Finally, the Office of the National Coordinator for Health Information Technology (ONC) has developed the FHIR Implementation Guide for the 2015 Edition Health IT Certification Criteria to support the adoption of FHIR in EHR systems.

Overall, FHIR is used by a wide range of organizations in the healthcare industry, from EHR vendors to government agencies. Its adoption will help improve healthcare data exchange and ultimately improve patient care.

However, FHIR standard is continuously developing and adapting to the dynamic nature of the healthcare sector. Some of its future plans include the development of new resources and profiles that will facilitate healthcare innovations in the field and increased participation of FHIR community by adding more healthcare practitioners, vendors, and other players.

The increasing use of FHIR standard in the industry can play an instrumental role in transforming the management of healthcare information and making significant strides in improving health care service delivery.

The introduction of FHIR should be considered to make the healthcare more interoperable.

With FHIR implementation gaining momentum, it may potentially become one of the most revolutionary approaches to exchanging healthcare information.
