The digital shift in collecting and managing patient health information has revolutionized healthcare delivery and practices. The EHR systems have encouraged new ways to be instilled in patient data management, and this further optimizes the workflows of the practices.

However, an EHR system can only work at its full potential when it is able to seamlessly connect with other EHR systems. This smooth flow of information exchange between various systems can foster quality care and coordination between healthcare providers.

Achieving interoperability of EHR and EMR systems has become a necessity for a smooth workflow, coordination, and care delivery in modern-day healthcare practices. However, achieving healthcare interoperability is easier said than done. The entire process is filled with challenges, and to make the EHR system relevant for a long time, overcoming these challenges is extremely important.

In this blog, we will oversee the challenges, solutions, and best practices in EHR and EMR system interoperability.


Why is EHR Interoperability Important?

Modern-day healthcare practices have become extremely data-driven. From using data to identify diseases to using it as evidence to make clinical decisions, EHR has today become the connecting link of the healthcare system.

Making this system interoperable helps in better coordination and in bringing everyone involved in the care team on the same page. This directly contributes to improving the care quality and efficiency of healthcare practices. 


Some of the primary benefits of EHR interoperability are:

1. Patient-Centric Care: The EHR system keeps the patient information in one place, and by making it interoperable, different healthcare providers can have easy access to it. This fosters better coordination between healthcare providers in a defined workflow, bringing everyone on the same page and working towards the same goal, which is to improve patient outcomes.

2. Reduces Cost: When providers have access to the complete health history of the patient, the chances of medical errors become very low, and the duplication of tests and care plans can be eliminated. This reduces the overall health cost for patients and helps to prevent unnecessary tests, procedures, medication errors, etc.

3. Improved Coordination and Communication: When the exchange between different healthcare systems is smooth, quick, and accurate, providers can communicate at a faster rate and coordinate better to get the desired outcomes. 


EHR Interoperability Challenges

Making an EHR system interoperability is important but also a difficult task at the same time. Some of the major challenges in achieving EHR Interoperability are:

1. Data Consistency and Standardized Structures: The data in the healthcare system is inconsistent and unorganized due to the lack of standardization and uniformity in formats. This is one of the biggest challenges in achieving EHR interoperability.

For example, a single patient record contains comprehensive information, including medical history, treatment plans, etc. Since this non-uniformity in data format is different in every EHR system, the system finds the data difficult to interpret and exchange in the right manner.

Establishing and using standardized data formats such as HL7 and FHIR can be an effective solution to achieve EHR interoperability.

2. Patient Data Privacy and Security: EHR deals with sensitive Patient Health Information (PHI), which makes it prone to cyber-attacks. The network of various systems provides enough entry points for cyber attacks.

Apart from that, EHR systems involve the exchange of this sensitive information across different platforms and systems. This increases the risk of data breaches. Any unauthorized access to patient data can lead to severe consequences like identity theft, fraud, etc. 

Here healthcare organizations need to safeguard patient data and maintain its privacy to ensure the security of personal health information. An effective way to ensure that is by developing robust APIs and compliance with regulations like HIPAA and GDPR.

3. Communication Standards Across EHRs: As of now, there are no set interoperability format standards in healthcare. This has made healthcare organizations develop their own standards to follow. 

Though these standards have effectively increased the internal workflow, the lack of standardized format, common vocabulary, and inconsistent data models have made it difficult for EHR systems to communicate and exchange data between themselves.

This improper communication can lead to duplication of tests and procedures, increase the chances of medication errors, and account for delays in diagnosis processes.

A proactive initiative must be taken by healthcare organizations, like developing standardized formats, using health information exchanges, etc., which can help set the standard and enhance the sharing of data.

4. Cost and Technical Challenges: Making an EHR system interoperable is a costly affair. The healthcare organization has to invest significantly in its infrastructure and resources. 

Adapting to legacy systems, bringing in relevant IT resources, and overcoming technical complexities pose a significant hurdles in achieving it. Along with that, the software customization and integration efforts further influence the cost of EHR software development.


Solutions to Improve EHR Interoperability

Achieving EHR interoperability is indeed a difficult task, but it’s now impossible. Knowing the challenges can help you navigate through the challenges effectively.

Here are some of the best practices and solutions that can improve the interoperability of your EHR system:

1. Cloud-based EHRs: Data servers are often located at different locations, further complicating data storage and retrieval. With cloud-based EHRs, the integration process becomes easy with increased accessibility of the data.

Cloud-based EHRs improve the accessibility of data for clinical, lab, and pharmacy systems. By implementing this one process, not only does access and integration become easy, but it also provides robust security features, keeping the data safe and eliminating the risk of unauthorized access.

2. Use Open Application Programming Interfaces (API): Developing APIs is one of the best practices used in achieving EHR interoperability. It allows different independent applications and systems to communicate in a better way.

APIs also encourage the smooth flow of data and protect sensitive patient health information better.

3. Blockchain for Network Provider Identification (NPID): The rise of the use of blockchain technology has been a rising trend in the healthcare industry. Since it is decentralized and records the transitions in a permanent and verified way, it adds another layer of security to data modification, access, and theft. 

Furthermore, the risk of data loss is minimized with unique security features like audit trails, which enable patients and providers to access medical records through a more secure and private network.



EHR interoperability is driven by challenges that can create delays in diagnosis and treatment. However, achieving interoperability can be simplified with best practices and innovative solutions. Here, the adoption of interoperability standards can improve the efficiency of healthcare providers and encourage data-driven practices, benefiting both patients and healthcare providers in many different ways.
