Open information systems and data security in medicine.

Area of Science:

• Health Informatics
• Medical Information Systems
• Health Law and Ethics

Background:

• German healthcare reform necessitates efficient hospital information systems (HIS).
• Big hospitals require integrated systems for seamless departmental and subsystem functionality.
• Regional cancer registries, like those at Cancer Centres, also demand robust information systems.

Purpose of the Study:

• To outline the necessity and possibilities of open systems in HIS.
• To discuss different levels of application integration within healthcare.
• To present concepts and realizations for data security and protection in HIS and cancer registries.

Main Methods:

• Discussion of open system features: portability, scalability, and interoperability.
• Analysis of practical implementations in Magdeburg University Hospital's HIS and regional cancer registry.
• Examination of legal aspects of medical data handling and security measures.

Main Results:

• Open systems are crucial for modern HIS, enabling user-near applications and complex integrations.
• Practical examples demonstrate the successful implementation of open HIS principles and integrated communication structures.
• Concepts for data security and protection, including hardware-based access control and encryption, are presented and applied.

Conclusions:

• Open systems are essential for efficient, scalable, and interoperable hospital information systems.
• Integrated communication structures in healthcare demand stringent data security and protection measures.
• Hardware-based access control and encryption are vital for safeguarding sensitive patient data in HIS and cancer registries.
