FHIR vs. HL7: EHR-wise, it’s an acronym you can easily relate to.

Most people in healthcare are familiar with Health Level 7 (HL7), but not everyone understands it at a technical level. While they may know they want software that’s HL7-compliant, many may not grasp the specifics of how HL7 interfaces between different healthcare systems.

On the other hand, Fast Healthcare Interoperability Resources (FHIR) has been around for several years but hasn’t achieved the same level of recognition. Recently, however, FHIR has gained significant attention, especially after being adopted as the preferred healthcare interface by major players like Apple and CMS.

It’s important to note that FHIR is a subset of HL7, which means there’s no inherent competition between the two systems or the companies implementing them. Apple and CMS have highlighted FHIR’s potential by launching a patient-focused mobile app that allows individuals to securely access and manage their medical records.

With the FHIR app, patients can quickly check everything from their eligibility for preventive care to the status of unpaid claims right from their iOS devices. They are able to “pull” their health records from any organization linked to Apple and CMS. This powerful combination of the FHIR application programming interface (API) and web services suggests that the future of healthcare technology could mirror the integration seen in social media platforms.

In contrast, traditional HL7 interfaces typically require a programmer or a team of developers to connect the necessary systems, and these interfaces must be continually supported and maintained to ensure their effectiveness. FHIR streamlines this process, simplifying what was once a complicated EHR interfacing method.

For example, health information exchanges (HIEs) have struggled to gain traction as a seamless solution for sharing patient information. However, the FHIR app and API can facilitate communication among various sources including EHRs, mobile applications, and devices.

The essence of APIs lies in providing a secure, public interface that allows authorized applications to send and receive data with the appropriate security measures. This is akin to having a key to open a locked door, rather than forcing it down with an ax.

HL7 designed FHIR specifically with EHRs in mind, ensuring that its primary goal is to create EHRs that are compatible with FHIR and easily interoperable with other healthcare applications. On a technical note, the FHIR 4 draft standard outlines various data formats and elements, referred to as “resources.”

A recent JASON (CMS) taskforce report has identified FHIR as the most promising candidate for an API-based approach. It has even suggested that FHIR should be included in the compliance criteria for stage 3 of meaningful use (MU). It certainly appears that FHIR is on track to become a standard, if not the standard, for healthcare API interoperability. Considering HL7’s strong foundation in the healthcare interface sector, FHIR seems destined to become a go-to solution for any EHR user and patient looking to manage their data effectively.
