Streamlining Healthcare App Development with Interoperability

The healthcare world is changing fast, and new technological advancements are its big builders. People are seeking easier and quicker ways to look after their health, and doctors aim to give better care more smoothly. Therefore, there’s a big rise in health apps being made. But, these apps need to work well with current health information systems to truly shine. To do this, the healthcare app development company uses HL7 integration. Here is your guide to learning how this integration lets healthcare information be used easily and for the betterment of patients.

What is HL7 Integration?

HL7 or Health Level Seven, is a set of international standards that format, and share healthcare information among Healthcare Information Systems (HIS). Therefore, healthcare app developers can ensure their apps communicate well with Electronic Health Records (EHRs), Lab Info Systems (LIS), and Picture Archiving and Communication Systems (PACS).

The Must-Know Benefits of HL7 Integration

HL7 integration brings many good things for both healthcare workers and the people they look after. Here’s a closer look:

  • Improved Data Accuracy and Consistency: HL7 makes sure data is shared commonly, lowering mistakes and mix-ups that can happen with hand-typed data. This means more precise and trustworthy patient info, key to smart choices by doctors.
  • Enhanced Patient Care: HL7 lets health apps talk to each other and the main health systems. This means doctors get a full picture of your health. They can make smarter choices, plan treatments just for you, and make sure you get the best care.
  • Increased Efficiency and Productivity: HL7 automates sharing between systems. This means less typing for healthcare workers. They save time and can focus more on caring for you.
  • Improved Patient Engagement: With HL7, you can see your own health info, test results, and more on health apps. This helps you be more active in looking after your health.
  • Reduced Costs: HL7 can make office work smoother and cut down on paper use. This can save a lot of money for health groups.

HL7 Integration for Mobile App Development in the UAE

The UAE health sector is growing fast, thanks to government plans and a rising need for top-notch health services. A mobile app development company in UAE is key in changing this area digitally by creating new health apps. By using HL7 in their apps, they can make sure their apps work well with the UAE’s health systems. This not only helps patients and doctors in the UAE but also helps build a more joined-up and working health world.

HL7 Standards & Implementation

HL7 isn’t just one rule but a set of rules for sharing data in different ways. Here are two main paths for making health apps:

  • HL7 v2.x: This is the old one, offering a strong and well-set for sharing a lot of health data. It uses a setup with messages made of parts, which have smaller parts and even tinier parts. Though strong, v2.x can be hard to put into use because of its detailed setup.
  • HL7 FHIR (Fast Healthcare Interoperability Resources): This new one is becoming popular for its easy-to-use way. FHIR uses modern web tech like RESTful APIs and JSON to make sharing data simpler. This makes it great for making mobile apps because it’s light and easy to change.

Integrating HL7 involves several steps:

  • Requirements Analysis:  This initial phase involves identifying the specific data your app needs to exchange with HIS and the functionalities required for seamless integration.
  • Standard Selection:  Based on your app’s needs, choose the most suitable HL7 standard (v2.x or FHIR) for your project.
  • Message Mapping:  Define how data elements within your app will be translated into the corresponding HL7 format for transmission.
  • Interface Development:  Develop the technical components within your app that will handle sending and receiving HL7 messages. This may involve utilizing middleware or specialized libraries.
  • Testing and Validation: Rigorously test the HL7 integration to ensure accurate data exchange and identify any errors. This may involve using HL7 validation tools and simulating various data exchange scenarios.
  • Deployment and Maintenance: Deploy the integrated app and establish ongoing monitoring processes to ensure the HL7 connection remains functional and secure.

Key Challenges for HL7 Integration

HL7 linking opens up many options for health apps, but going through it requires you to think about many important points. Here’s a close look at these points, with ways to make sure the link works well and goes without trouble:

  1. Security: Building a Fortress Around Patient Data

Challenge: HL7 integration involves transmitting sensitive patient data. Ensuring this data remains secure throughout the exchange process is paramount.


  • Compliance is King: Always stick to health data safety laws like HIPAA in the US and GDPR in the EU. Use strong checks on who can see data, make sure the data sent is safe, and check for security often.
  • Mitigate Vulnerabilities: Always make sure the software for HL7 links is up to date to keep out risks.
  • Educate and Train: Educate staff involved in app development and keeping the app how to care for private patient info.
  1. Scalability: Building for Growth

Challenge: As your app user base and data volume grow, the HL7 integration needs to be able to handle the increased load without compromising performance.


  • Choose Wisely: Select an HL7 integration solution that is scalable and can accommodate future growth. Consider cloud-based solutions that offer automatic scaling capabilities.
  • Modular Design: Design your HL7 integration with a modular architecture. This allows for easier upgrades and expansion of functionalities as needed.
  • Performance Monitoring: Continuously monitor the performance of your HL7 integration and identify potential bottlenecks. This allows for proactive scaling measures to be implemented before performance suffers.
  1. Interoperability: Aiming for Universality

Challenge: The healthcare landscape is filled with diverse HIS systems from various vendors. Your HL7 integration needs to be interoperable with a wide range of systems, not just a specific one.


  • Standardization is Key: Strictly adhere to chosen HL7 standards (v2.x or FHIR) during implementation. This ensures compatibility with other systems that also follow the same standards.
  • Testing is Paramount: Thoroughly test your HL7 integration with different HIS systems to identify and address any interoperability issues. Consider using industry-standard testing tools.
  • Embrace Adaptability: While aiming for broad compatibility, be prepared to adapt your integration for specific HIS systems if necessary. This might involve implementing custom message mapping or adapters.
  1. Testing: Leaving No Stone Unturned

Challenge: Ensuring accurate and reliable data exchange is crucial. Any errors in the HL7 integration can lead to negative consequences for patient care.


  • Multi-layered Testing:  Set up a deep test plan that includes checking each part on its own, making sure parts talk well together, and testing the whole system as if it were being used for real.
  • Leverage Tools: Pick industry-standard tools that check if your messages are built right and follow the HL7 rules you’re using.
  • Test, Refine, Repeat: Testing should be kept on. Identify and address any errors discovered during testing before deploying the integrated app.


HL7 is a powerful integration tool for building healthcare apps. It lets healthcare apps do more for both people who need care and those who give it. As the world of healthcare keeps using more digital tools, being able to work with HL7 will be key to making sure healthcare apps can do their best. In short, a healthcare app development company that uses HL7 will be ready to create new solutions that change how healthcare is given. This will lead to a healthcare system that works better, does more, and puts the needs of patients first.
