Summary
Securely sharing electronic patient records (EPR) is crucial for efficient healthcare. This study introduces models for secure, distributed EPR systems, enhancing communication between healthcare establishments (HCE) and health professionals (HP).
Area of Science:
- Health Informatics
- Computer Science
- Information Security
Background:
- The need for efficient, high-quality healthcare necessitates a shared care paradigm.
- Electronic Patient Records (EPR) are vital for communication and interoperability between healthcare establishments (HCE) and health professionals (HP).
- Ensuring trustworthy cooperation is paramount due to the sensitivity of personal medical information.
Purpose of the Study:
- To develop and introduce models for the analysis, design, and implementation of secure, distributed EPR systems.
- To support diverse user views, from management to IT professionals.
- To address requirements for distributed multi-user EPRs, focusing on policy agreements, authorization, and access control.
Main Methods:
- Utilizing the Unified Modeling Language (UML) methodology and the component paradigm for open, interoperable systems.
- Developing user-friendly toolkits for application and communication security services.
- Implementing security infrastructure, including cryptographic algorithms, health professional cards (HPC), digital signatures, and trusted third-party (TTP) services.
Main Results:
- A set of models for secure distributed EPR analysis, design, and implementation has been developed.
- Toolkits facilitate the integration of security services and infrastructure.
- Consideration of policy agreements, authorization, and access control for multi-user EPRs.
Conclusions:
- The developed models and tools enable secure, interoperable EPR systems supporting the shared care paradigm.
- Current security infrastructure developments, including cryptographic solutions and standards initiatives (CEN, ISO), are discussed.
- The approach facilitates trustworthy cooperation among healthcare stakeholders.
