HL7 Integration Services & Interface Development

The healthcare industry is one of the oldest sectors. It goes way back to humans first starting to tend to each other, mushing down leaves and mud to heal wounds, and so on. We can’t really call this an industry, but our history underlines the necessity of it. Slowly, we learned to keep medical records and started manually transferring them. It then became a fax-based transmission, and today, we share medical history digitally, securely, and almost seamlessly.

Since we do data exchange digitally, HIPPA and other various standards have been put in place since the mid-90s to increase the levels of interoperability in the healthcare system.

One of the challenges of clinical data exchange was its quality and structure. That’s why HL7 was developed to solve these issues. What HL7 does, we’ll discuss in this article and guide you to successful development and integration.

How does HL7 Integration Work: Seamless Exchange of Clinical and Administrative Data

HL7 integration is an important function in healthcare that helps in the easy flow of information between different medical systems and applications. Here, we list five key factors that will help you understand how HL7 integration works:

Standardization of clinical and administrative data

All medical facilities have their unique or specific medical data formats. This can be difficult for another facility to understand. HL7 creates a standard that can be understood by all facilities. Basically, it’s creating a mutual language for dozens of foreigners.

Message formatting

Messages sent from facility to facility all contain essential information that can’t be mistaken or interpreted differently. This is where HL7 comes in with a standard format that all clinics and facilities can understand.

Electronic medical record transmission

For healthcare providers to have continuous and safe access to patient health data, we need safe data exchange systems. HL7 formats the messages and transmits them between systems using MLLP.

Integration tools and middleware

HL7 integration is usually done with other integration tools or middleware that stand between the EHRs and translators and relay the information to the right place. This middleware can work with multiple connections and protocols and therefore, it is a good solution for the healthcare sector in exchange of data.

Continuous monitoring and compliance

HL7 integration needs to be maintained to avoid data corruption of electronic health records and adherence to legal standards like HIPAA in the United States. That’s why we recommend checking the systems periodically and regularly to sort out any problems.

To say it simply, HL7 integration helps healthcare organizations give their patients better care by making sure all their medical data is safe and transmitted correctly between different systems.

Benefits of HL7 Integration for Healthcare Organizations

We already explored what HL7 integration does. You may ask, what’s in it for me? And that’s a great question. Health Level Seven interface development has many real-life benefits that we’re sure you’ll find interesting:

• Enhanced interoperability: Your medical facilities will reduce mistakes made due to inconsistent data exchange formats
• Improved efficiency: Time is essential, especially in the healthcare sector, which is why HL7 integration is beneficial
• Better patient care: Once your medical professionals have easy and secure access to real-time and reliable data, they can deliver better patient care
• Cost savings: HL7 integration might seem like a costly purchase at first, but its’ long-term benefits have a huge effect on cost savings
• Regulatory compliance: You will be able to provide tools and services that adhere to HIPAA
• Scalability: Don’t worry about integrating your new HL7 into existing systems and messing them up. Professional services can conduct this integration without a hassle
• Secure data transmission: With secure messaging and other security measures, HL7 allows your doctors to transfer data without worry

These benefits are the reason successful healthcare organizations choose HL7 integration.

HL7 Integration: A 7-Step Guide for Healthcare Organizations

Implementing HL7 integration in a healthcare system is a complex process that requires careful planning and execution. We recommend consulting with a professional team that can help you implement HL7 effectively. Meanwhile, please take a look at our small guide on HL7 integration.

• Identify needs: What are your company’s needs? What kind of information do you want to exchange between systems? (e.g., patient data, lab results, billing information).
• Scope of the project: What’s the scope of your project? Define the systems involved, and the data flows.
• Create a project team: If you’re doing the integration in-house, you need to assemble a team of professionals with experience in clinical workflows, IT, and HL7 standards.

• Learn HL7 specifications: Your in-house team should know HL7 standards (HL7 Version 2.x, HL7 Version 3, or FHIR). A professional team is usually hired to meet these specifications.
• Define data structures: Now, it’s time to map out data structures that comply with HL7 standards.

• Design interface architecture: Your designers should create sketches of the architecture (using HL7 interface engines, APIs, etc.).
• Develop the interfaces: Then, developers will program the interfaces that will translate and route the data based on the HL7 standard on what to do. This is usually done through middleware or an integration engine.

• Internal testing: Once you have the program ready, it’s time for QA engineers to start testing the functions
• End-to-end testing: We recommend doing end-to-end testing, manual and automated testing, and more.
• User acceptance testing: Testers can create real-life scenarios, but it’s always smart to involve end-users to get better feedback.

• Deploy integration: It’s time to launch your HL7 integration and see how it performs.
• Monitor and optimize: This stage requires continuous monitoring of the performance. It helps gather user feedback and adjust errors if any were found.

• Regular updates: This is essential since your business grows and will require updated HL7. It’s also important to make updates to ensure adherence to standards.
• Compliance checks: Once isn’t enough. You have to regularly review your system for compliance with HIPAA and other standards.

• Training: Without training your end user (your staff, in this case), there’s no point in launching the system. Make sure everyone knows how to interact with it.
• Provide ongoing support: Create user manuals, employ technical writers, and so on. This is best done by a professional team.

HL7 (Health Level Seven) Integration using Application Programming Interfaces (APIs)

You know what’s the most modern approach to seamless communication between medical centers? HL7 integration using APIs.

APIs are a form of protocols that define how two or more software applications are to interact with each other. To this end, APIs in the context of HL7 refer to the means of exchanging health information between different healthcare IT systems, including EHRs, LIS, and billing applications.

APIs in HL7 integration support HL7’s latest version standards like HL7 FHIR (Fast Healthcare Interoperability Resources). These are some of the features that have been put in place to ensure that the implementation of FHIR becomes easier and more efficient: JSON, XML, HTTP, OAuth, and REST. This API-based standard enables the rapid integration of components and solutions that may be easily modified as healthcare organizations’ requirements change over time. APIs prove a good way of exchanging data and sharing information as they are flexible and scalable.

The use of APIs in implementing HL7 ensures that healthcare applications can easily and seamlessly share data in real time. For instance, when a patient is admitted into a hospital, their health record can be easily obtained from other medical facilities through API calls.

Why Healthcare Providers Outsource HL7 Integration?

Now, to explore the subject of why successful healthcare organizations prefer to outsource HL7 integration, rather than do it in-house. We already mentioned that HL7 interface development is a complex process. We mapped out seven steps of development and integration, and you can already tell that recruiting all the experts for this job will take weeks and even months.

Companies usually outsource certain services to save time on various processes, save money, and avoid making mistakes that skill gaps may create. We prepared a little list of why outsourcing is the best option for your HL7 integration:

Effective integration of the HL7 interface is a complex process and requires expertise

Let’s say you have a wonderful, talented in-house development team, QA engineers, and user-friendly UX designers. Do they have all the necessary knowledge to integrate HL7? You’ll notice there are some skill gaps, which can be found in professional outsourcing companies that have hundreds of professionals from around the world.

Outsourcing HL7 integration is cost-efficient compared to in-house development

You decided to hire professionals to fill in the skill gaps. The hiring process usually takes months, and it’s especially long when you’re looking for professionals with such specific knowledge. Outsourcing HL7 integration is relatively cost-efficient because outsourcing companies have access to a wide pool of talent, a better and modern tech stack, and skilled project managers who can make the development process flow like a river.

Outsourcing HL7 integration will give you time to focus on core business

We always say this! Owners of medical organizations, representatives, and decision-makers of medical facilities are often so busy with these tasks that they are easily delegated that sometimes, core business decisions and processes are neglected. Outsourcing even the smallest parts of data integration and the HL7 development process will save you the time needed for your business.

Professional HL7 integration services offer high flexibility

This is something that’s difficult to achieve with an in-house team. You’ll notice, as your healthcare facility grows, the needs of healthcare providers and administrative workers grow and change. Professional services can guarantee the scalability and flexibility within your HL7 that your company needs.
