Summary
Integrating existing health care information systems is crucial for meeting evolving clinical and managerial needs. The Healthcare Information Systems Architecture (HISA) standard provides a framework for system interoperability and proposes a global security model.
Area of Science:
- Health Informatics
- Information Systems Architecture
- Cybersecurity in Healthcare
Background:
- Existing healthcare information systems require integration and evolution to meet increasing demands.
- The CEN ENV 12967-1 standard, known as Healthcare Information Systems Architecture (HISA), offers a solution.
- HISA promotes interoperability through a middleware of common business services.
Purpose of the Study:
- To provide an overview of the key aspects of the HISA standard.
- To discuss the integration of authorization and security within the HISA framework.
- To propose a global security framework for healthcare information systems.
Main Methods:
- Review of the CEN ENV 12967-1 HISA standard.
- Analysis of architectural positioning for security and authorization.
- Development of a proposed global security framework.
Main Results:
- HISA enables seamless operation across local and geographical systems using a common information heritage.
- The paper details the placement of security and authorization within the HISA architecture.
- A comprehensive global security framework is presented.
Conclusions:
- The HISA standard is essential for modernizing healthcare information systems.
- Effective integration of security and authorization is vital for robust healthcare IT infrastructure.
- The proposed framework enhances the security posture of integrated healthcare systems.
