A Blockchain-Based Medical Electronic Health Record Big Data Sharing Scheme.

Area of Science:

• Health Informatics
• Computer Science
• Blockchain Technology

Background:

• Growing investment in medical informatization highlights issues with current Electronic Medical Record (EMR) systems.
• Existing EMR systems suffer from poor interactivity, weak security, and limited data sharing capabilities.
• Uneven distribution of medical resources and lack of patient access to records are significant challenges.

Purpose of the Study:

• To propose a novel blockchain-based system for secure and efficient sharing of EMR big data.
• To address the limitations of independent EMR systems and enhance patient data control.
• To improve cross-hospital care and facilitate data exchange between regions with varying medical resources.

Main Methods:

• System design based on field research and surveys.
• Implementation of blockchain technology for decentralization, transparency, and encryption.
• Focus on protecting patient rights while maintaining hospital control over data.

Main Results:

• The proposed system enhances the usability of EMRs for cross-hospital care.
• Secure and efficient data sharing is achieved between geographically diverse regions.
• Improved data integrity and accessibility for patients and healthcare providers.

Conclusions:

• Blockchain technology offers a robust solution for EMR big data sharing challenges.
• The system promotes equitable distribution of medical resources through enhanced data accessibility.
• This approach supports a more interconnected and secure healthcare ecosystem.
