HL7 EMR Integration: Interoperability That Goes Hand in Hand

Paul Kovalenko Paul Kovalenko | September 27, 2023 | 7 min

Electronic health records were created to make information travel between hospitals, doctors, and patients easier and more reliable. The idea was great and would have been revolutionary, but there was an obvious flaw. Different hospitals use different EHR systems and types of EMR systems and data formats, so what will be displayed perfectly well in one institution will not work in the other. Because of this data jumble, the US spends $30 billion a year alone to deal with the consequences of the lack of orderly data flow.

The difficult task of interoperability was accepted by Health Level Seven. In this blog post, we are going to give you a glimpse into the standards developed by this organization and HL7’s impact on healthcare interoperability.

Why is HL7 Important for the EHR/EMR?

Health Level Seven International, founded in 1987, fosters global collaboration for health system standardization, notably in HL7 and EMR interoperability. It sets standards for messaging in healthcare administration, logistics, finance, and clinical processes, enabling seamless communication among various systems. Additionally, HL7 defines XML-based clinical document standards and supports Arden Syntax for healthcare knowledge representation. Visit their website for valuable resources on interoperability and development. Headquarters in Michigan, HL7 engages in rigorous standardization processes, recognized by ANSI and ISO.

Key Benefits of HL7 EMR Interoperability

HL7 standards were developed to help healthcare institutions get helpful digitalization. Their guidelines helped laboratories, registries, pharmacies, payors, local and state departments of health, healthcare institutions, and developers create solutions that matter, and stay for a long time to support the huge diversity of healthcare systems. Thus, HL7 EMR interoperability offers numerous benefits.

Establishing Smooth Data Exchange Between Different Parties

Before health records moved to electronic form, the process of exchanging information between hospitals or doctors had lots of obstacles. Doctors had to send photos of records via email or fax, or patients had to take physical records from one place or specialist to another. Even after EHR/EMR was introduced, there was still the problem of different systems not being able to read the same data, so email and fax were still widely used.

Using HL7 to achieve interoperability in health IT made it possible to view a patient’s history, test results, or examination notes from anywhere. Moreover, there was no delay, as the information gets updated in real time!

Eliminating Any Errors

When data goes through different systems, it is likely to arrive with mistakes. It is also common in healthcare when medical staff cannot find a health record because of system differences and they create a new one, resulting in a significant number of duplicate records and lost background that can be essential to the patient’s treatment. HL7 EHR interoperability eliminates these issues and allows for error-free transfer of information.

Now, physicians can also integrate lab test results and make examination notes on any device, straight from the patient’s room. This practically eliminates the possibility of human error that existed before because of the manual transfer of data from paper to the computer.

Saving Time Needed to Retrieve Data or Develop New Tools

Doctors no longer need to figure out how to share information; no need to choose the right format or sending method. With interoperability, they can just go to the database and find the right patient from any device or system.

It is also time-effective when it comes to developing new healthcare software and integrating it with the existing EHR/EMR systems. HL7 already has a set of instructions with must-have features and their FHIR standard makes integration as simple as it can get.

Promoting Innovation by Simplifying EHR/EMR Integration Processes

One of the reasons why healthcare software was not the fastest to progress was interoperability issues. When creating a new practice management software or telehealth app, you have to integrate an EHR/EMR system to deliver the full experience. Otherwise, the app will not function properly and be pretty much useless. It was very difficult to integrate the system before but with Health Level 7 interoperability and FHIR API, it is as simple as in any other digitally developed industry. It will definitely contribute to the rise of health tech and new types of software which will truly embrace every single aspect of managing healthcare institutions.

Seamless HL7 EMR Integration: Empowering Healthcare Systems

Data Mapping Complexity

Navigating the intricacies of data mapping between HL7 and EMR systems poses a significant challenge. These systems often use different data structures, codes, and terminologies, making alignment and translation a complex endeavor.

Standard Variability

HL7 standards themselves can vary, such as HL7 v2 and HL7 FHIR, each with its own nuances. Integrating these standards with EMR systems that may also have custom data formats adds another layer of complexity.

Data Security and Compliance

Ensuring data security and compliance with regulations like HIPAA in the context of HL7 EMR integration is crucial. Protecting patient information during data exchange requires robust encryption and access control mechanisms.

Real-time Data Exchange

Achieving real-time data exchange between HL7 and EMR systems is a persistent challenge. Delays in data transmission can impact clinical decision-making and patient care.

System Scalability

As healthcare systems grow, scalability becomes a challenge in HL7 EMR integration. Ensuring that integration solutions can accommodate increasing data volumes and users is essential for long-term success.
