Enhancing EHR Interoperability and Security through Distributed Ledger Technology: A Review

Area of Science:

• Health Informatics
• Computer Science
• Information Security

Background:

• Electronic health records (EHRs) face significant interoperability challenges due to fragmented systems and varied standards.
• Security concerns and lack of data integrity impede efficient healthcare data exchange and patient care.

Purpose of the Study:

• To propose a novel solution using distributed ledger technology (DLT) to enhance EHR interoperability, security, and transparency.
• To outline a strategic implementation framework for DLT in healthcare, addressing privacy and security concerns.

Main Methods:

• Leveraging the decentralized and immutable properties of DLT, including blockchain, for secure health data exchange.
• Developing a strategic implementation approach with timelines, resource allocation, and stakeholder engagement.
• Exploring necessary standards and protocols for DLT integration and interoperability, supported by case studies.

Main Results:

• DLT enhances data security, integrity, and transparency in healthcare systems.
• The proposed framework facilitates more efficient and secure information exchange across platforms.
• Case studies demonstrate the effectiveness of the DLT-based framework in improving interoperability.

Conclusions:

• DLT presents a novel pathway to address persistent EHR interoperability issues, enabling secure and efficient health data exchange.
• Identifying essential standards and protocols is crucial for integrating DLT with existing health information systems.
• This work facilitates a smoother transition towards enhanced healthcare interoperability through DLT adoption.
