- Electronic health records (EHR) interoperability is the ability to effectively exchange and use information between different EHR systems.
- This capability makes it possible to provide continuity of care by making information about a patient’s medical history easily accessible to other providers once they have been treated at one hospital.
In the realm of healthcare technology, the term “EHR interoperability” refers to the capability of electronic health record (EHR) systems to communicate, exchange, and coordinate information effectively across different healthcare providers and settings. This seamless data sharing is critical to enhancing patient care, improving efficiency, and reducing medical errors.
Understanding EHR interoperability
Electronic health records (EHR) interoperability is the ability to efficiently exchange and use information between different EHR systems. This ability allows a patient’s medical record information to be easily accessed by other healthcare providers once the patient has been treated at one hospital, allowing for a continuum of care to be provided.
Interoperability is a core element of an EHR system that allows for the sharing of data between different systems and organisations to enable comprehensive, continuous patient care. Specifically, interoperability consists of two essential components: the ability to securely transmit data and the ability to interpret and use that data. Ensuring that data between different EHR systems can be accurately interpreted and effectively used is accomplished through means such as standardised data formats, coding and terminology sets.

Importance and benefits of EHR interoperability
The significance of EHR interoperability lies in its potential to transform healthcare delivery. It enables healthcare professionals to access comprehensive patient information, regardless of where care is provided, thereby facilitating informed decision-making and continuity of care.
Moreover, it supports the integration of various healthcare services, enhances patient safety through reduced medical errors, and can lead to cost savings by minimizing redundant tests and procedures.
The benefits of EHR interoperability are manifold:
- Improved patient care: By providing a complete view of a patient’s health history, healthcare providers can deliver more personalized and effective care.
- Enhanced efficiency: Streamlining workflows and reducing the need for redundant data entry or tests.
- Patient satisfaction: Patients value the convenience of having their medical history readily accessible at different healthcare facilities.
- Cost reduction: By avoiding unnecessary duplication of services and improving overall operational efficiency.
Secure data transfer between EHR systems
Secure transmission of data between EHR systems is mainly achieved in the following ways:
- Encryption technology: This is an important means of protecting information. By encrypting the data stored in the EHR system, even if the data is accessed by hackers, it is difficult to be deciphered and utilised.
- Advanced encryption technology: The EHR system uses advanced encryption technology to encrypt and store sensitive data such as patients’ personal information, medical history, and test results, which can only be accessed by authorised medical personnel.
- Cloud encryption technology: Integrating cloud encryption technology and text mining strategies in the EHR system aims to ensure patient privacy while promoting quality of care by optimising data management and protection.
- Network transmission encryption: To address the security risks of data transmission based on wide-area networks, encrypted transmission can be used to ensure the security of data during transmission.
- Privilege control: The EHR system has a stricter privilege control and data encryption mechanism for the handling of sensitive information such as health records and medical records, which guarantees the protection of employees’ personal privacy information.
- Blockchain technology: A permissioned blockchain system based on Hyperledger fabric is used for EHR integration and data sharing, using a hybrid encryption system that combines the advantages of symmetric-key cryptography and public-key cryptography, and data is stored in HIPAA-compliant cloud storage.

Challenges of EHR interoperability
Despite the clear benefits, achieving EHR interoperability is fraught with challenges. These include:
- Technical barriers: Different EHR systems may use incompatible formats or standards, making data exchange difficult.
- Lack of standardization: Absence of universal standards for data representation and communication protocols.
- Security and privacy concerns: Ensuring the protection of sensitive patient information while facilitating data sharing.
- Cultural resistance: Healthcare providers may be reluctant to adopt new technologies or share patient data due to competitive or proprietary interests.
EHR interoperability is a pivotal aspect of modern healthcare systems, offering substantial advantages for patient care and operational efficiency. As the technology and policies evolve, the goal is to create a healthcare environment where information flows freely and securely, empowering healthcare providers to deliver the best possible care.
