So read on to fully comprehend HL7 significance, how it works, why systems need HL7 data integration, how to integrate an HL7 with APIs, and the benefits of HL7 in healthcare.

Why Is HL7 Integration Needed in the Healthcare Industry?

Healthcare providers use software and electronic systems to perform various activities such as billing, medical record maintenance, telehealth, and patient record updates.

Such software may include the following:

• Hospital information system (HIS)
• Electronic medical record (EMR)
• Electronic health record (EHR)
• Lab information system (LIS)
• Radiology information system (RIS)
• Picture archiving and communication system (PACS)

All software solutions above communicate in different languages and formats, making data collection a complex process. As a result, HL7’s mandatory guidelines are necessary to ensure that data can be easily incorporated through healthcare systems.

By having a shared and common language in terms of content and structures for clinical classes, the value of electronic health records (EHRs) can be maximized. Information can also be shared without ambiguity or fear of misinterpretation, allowing for better care delivery.

Furthermore, as data sharing becomes more convenient, the administrative and logistical burden on providers will be reduced. More information will be readily available, and clinical efficiency will increase, allowing medical practitioners to make better clinical decisions.

HL7 Integration by Using Application Programming Interfaces (APIs)

As useful as the HL7 standards are, traditional integration techniques are insufficient to meet the needs of modern healthcare providers. After all, as the industry and technologies evolve, medical professionals will need to accept non-clinical applications.

Mobile and SaaS applications have become increasingly intertwined with the online medical industry, but they use data formats that are unfamiliar to the majority of clinical systems. In order to seamlessly connect these radically different message standards, APIs must be used to scale these integrations.

Since APIs provide a standardized and public interface, any approved application with the proper security authentication may send and receive data. This enables fast and smooth communication between multiple systems and third-party applications. Businesses may also benefit from being able to send data to different government departments to meet public health reporting standards.

Healthcare providers can also exchange patient health records with community care organizations and other third-party medical facilities in order to influence informed medical choices. Furthermore, an HL7 integration case study reveals that by reusing the same collection of APIs with these associated partners, it would be possible to cut communication time by more than 50%.

Another benefit is that APIs provide an amazing opportunity for real-time interoperability by including methods for posting, updating, and retrieving complex data.

Key Advantages of HL7 Standards in Healthcare Industry

Medical facilities can benefit from HL7 healthcare standards integration in several ways. Here are the main advantages of HL7:

Maintaining Data Consistency in the Infrastructure

As already stated, different healthcare systems use specific communication means and formats. That creates an issue of smooth data exchange. Yet, by using HL7 standards, healthcare organizations can ensure data consistency across their infrastructure and update their legacy software.

Simplifying the Process of Medical Decision-Making

There is no room for hesitation in the healthcare industry. In many emergencies, doctors must decide on the patient’s treatment right away. By integrating HL7 standards, healthcare professionals can quickly access the necessary data and provide instant medical care.

Reducing Investments in New Services and Programs

Healthcare providers can continue using their current information systems using the HL7 interface engine, which would expand their systems’ life and ROI.

Allowing Standardized Data Sharing with Other Sources

Medical organizations often need to share their data with external healthcare facilities, research centers, or third-party service providers. The use of HL7 in healthcare ensures the smooth transmission of standardized data with a high level of security.

Reducing Risks and Errors

As HL7 is a set of formatting standards, there would be less ambiguity within health records, reducing the possibility of mistakes.

Saving Time and Money

The HL7 standards would simplify and accelerate data exchanges, reducing administration and operational time and costs.

Making Services Easier for Patients

Patients will be able to access their results and records online conveniently. They will also be relieved of the time-consuming process of transporting their documents from specialist to specialist.

Providing Better Patient Treatment

HL7 integration makes life easier for patients not only due to smoother exchange of health data. It also enables doctors to improve the quality of their medical services, as all health data, prescriptions, and treatment standards are at their fingertips.

How HL7 Is Used in Healthcare

Please consider some examples of HL7 use cases to understand how the benefits we mentioned today work in practice better. Here are some options for the integration of HL7 interfaces:

Automation of Processes

Data exchange will become automated with HL7, reducing administrative burden while improving clinical performance.

EHR Management for Incoming Patients

HL7 integrated software systems will enable data transfer and storage, allowing healthcare providers to access the medical files of their incoming patients effortlessly.

How to Build an HL7 Interface for Your Healthcare Company

If you want to implement HL7 interfaces standards in your healthcare company, keep reading our step-by-step integration guide. The process of HL7 integration consists of the following stages:

1. Gather Sample Data

First, you need to get sample data from the healthcare system. We recommend using a data-gathering tool to help you collect all information in a standardized and structured format.

2. Analyze the Gathered Data and Its Structure

If you gathered data with an HL7 listener tool at the previous stage, you’d get data in an HL7 message format. Once you’ve collected that information, you should analyze it with suitable software like a message transformation app. This tool will help you structure all data into tables and segments.

3. Build the Messaging, Segmentation, and Table Grammar

The next stage of HL7 hospital integration involves identifying the most suitable type of segment and table grammar for gathered data. The selection of the appropriate type depends on the functions you need your healthcare system to perform.

4. Design and Code Your Interface

At this point, you should develop the interface, i.e., write its backend and frontend code. Then, ensure the efficient logging strategies for your HL7 interface to operate correctly. Plus, you should design a user-friendly interface at this stage.

5. Deploy and Test Your Interface

Finally, you can conduct testing and quality assurance to ensure your HL7 interface is bug and error-free. You may apply the message transformation app as a QA tool. After fixing all the issues, you can deploy the interface.

These five straightforward steps will help you integrate HL7 standards into your healthcare organization.

Custom HL7 Interface Cost and Maintenance

Now that you know how to build an HL7 interface in healthcare organizations, you may wonder how much it all costs. Let’s consider the expenses associated with compliance to HL7 standards.

Custom HL7 Interface Design and Development Expenses

If you build a custom HL7 interface, the cost will be higher than if you use other tools like APIs for interface integration. For example, bespoke software design and development will require about $8,000 and more for a single interface. Yet, healthcare facilities often need more HL7 interfaces for various procedures; thus, the expenses may be higher.

Using APIs or interface engines can significantly reduce your development expenses. In this case, you’ll need to pay for licensing, but you’ll get your HL7 interface faster and still for a more reasonable price.

An HL7 integration case study reveals that by reusing the same collection of APIs with these associated partners, it would be possible to cut communication time by more than 50%.

Port Expenses

Another price-influencing factor includes port fees. These are expenses for introducing a point of import and export to your HL7 interface. You'll require four such ports if you need to connect two systems, i.e., two HL7 interfaces.

One port integration will cost you about $5,000. As a result, connecting two HL7 interfaces requires $20,000.

Data Transfer Expenses

Once you cover your design, development, and port expenditures, you need to consider data transfer fees. You can use SSL for secure data transmission at a reasonable price. It’ll cost you about $60 per year, but you can find even cheaper options.
