What Does an HL7 Interface Do and What are its Benefits?

The “HL7 interface” is widely used in the healthcare and IT industry. “Interface engine” and “integration engine” are two more terms. The definition of an HL7 interface consists of two elements.

Health Level Seven International (HL7) interfaces are often examined when a health care institution is adopting new or upgrading current software.

What is the HL7 interface?

Health level 7 (HL7 interface) refers to international standards for interchange and integration. It also successfully shares and retrieves electronic health information to deliver healthcare services (HL7). 

HL7 interface is a global, user-friendly standard that allows two or more healthcare management systems to communicate. The health-related data, such as patient records and billing information, will be sent in one or more HL7 messages.

What does an HL7 interface do?

The HL7 interface is an interconnection that allows information to be transmitted between multiple system endpoints, while the HL7 protocol permits data sharing and exchange. 

An HL7 interface enables users to send and receive data between applications and software systems. Therefore, Healthcare organizations must connect and empower their data systems with the appropriate communication tools for this exchange.

It also refers to the transmission of administrative data between software applications using a defined communications protocol. Different software programs and health systems must constantly communicate data regarding healthcare technology. 

What is the importance of the HL7 interface in healthcare?

  • Integration with other systems:

Healthcare companies rely on cutting-edge software to carry out their everyday operations in today’s environment. However, each piece of software has its functions and capabilities. 

Some tools have minimal functionality, while others have complex features. However, the fundamental issue is that some healthcare companies utilize vast and complicated data systems.

The HL7 standard’s major goal is to provide a universal protocol that allows any healthcare company with the appropriate permissions to access and retrieve data from other healthcare software systems.

  • Workflow automation:

While EHR systems are the most well-known and widely used option for practice workflow automation, it is sometimes difficult to communicate effectively across multiple EHR and other information sources, such as lab services.

HL7 interface can increase interoperability and data transmission in this situation. Regardless, the systems use older communication technologies or modern APIs. 

If a clinic or clinical association does not have a full EHR, HL7 can fill in as a workflow automation device.

  • Collaboration:

Because HL7 interfaces are a vital resource for storing and transmitting data, it has the potential to be used and collaborated on by people all over the world. 

One of the main challenges in the medical care industry is a collaboration between traditional administrative institutions and the quickly growing health tech sector and private practices.

How does the HL7 interface work?

The two key drivers of technology in the healthcare sector are electronic health records (EHRs) and interoperability. The use of HL7 is extremely important in interoperability.

You may immediately comprehend how HL7 works by comparing it to the process of connecting millions of websites on the Internet. They may be written in different languages, such as PHP, .NET, or WordPress, but they all adhere to the same W3C standards. 

HL7 protocols, on the other hand, establish a framework for retrieving, sharing, and integrating electronic health data. 

HL7 uses several standards such as application, messaging, and following a set of HL7 protocols for packing and communicating with different systems. It accomplishes this by defining the data’s language, data type, structure, and how it must be packaged.

Benefits of HL7 interface for healthcare practices:

The healthcare business in the United States is extremely regulated, and the vast volume of medical data gathered regularly makes it even more complicated. 

A standard framework for data exchange has several advantages; let’s look at the most important ones.

  • Ensuring data uniformity:

It may effortlessly move patient information and other health information from admission through diagnostics, treatment, and billing. Moreover, it guarantees data homogeneity between different applications inside and between medical institutions.

  • Automation of workflows:

Manual data input takes time, and automating repeated operations saves both energy and money. In addition, a unified HL7 data pipeline can aid in synchronizing data changes. 

For example, exchanging records, lab tests, and medications can reduce the need for human data entry.

  • Facilitate information exchange with regulators:

Healthcare providers must regularly exchange information with authorities, notably in the United States, to fulfill public health reporting criteria. 

By sharing data electronically, medical systems that are HL7 compliant can streamline this procedure and decrease the administrative strain. 

It is especially essential when it comes to medical device specs being shared. Biopharmaceutical companies that need to exchange information about drug development and clinical trials are in the same boat.

  • HL7 improves clinical productivity:

Improved communication across different clinical associations considers the gathering of more relevant data. Therefore, it may enhance the quality and productivity of a patient’s treatment. 

HL7 enables faster and more efficient information interchange, allowing doctors to access up-to-date data. It also provides a broader clinical perspective due to the availability of more permanent records.

  • Eliminate administrative errors:

Clinicians may access important data from many sources using HL7 FHIR standards and ensure that all information is coordinated and appropriate. 

HL7 interface reduces time and provides greater accuracy when handling patient records by reducing the need for physically noting and filling out data.

  • Patients may readily access their records:

Patients will be able to view their records and fresh updates online when EHR records are combined with interoperability. 

When it comes to consulting various professionals, this is a huge plus. The time-consuming task of hauling around a stack of paperwork or presenting a complete medical history is eliminated instantaneously.

  • Reduce new technology upgrade investments:

While introducing a new HL7 framework requires an initial expenditure, the expenses will be lower in the long run. 

Because it leverages the messaging capabilities of the HL7 framework to communicate with newer systems, it can prolong the system life of older systems.


It is not a surprise that the HL7 interface is improving every element of healthcare today. Suppose you are ready to use the HL7 interface’s features to improve your practice productivity. 

In that case, we at intelyConnect are well aware of the revolutionary phase the healthcare sector is undergoing.
