This study presents a future-proof Electronic Health Record (EHR) architecture, emphasizing reliability and flexibility for lifelong patient data management. The new system design ensures data integrity and interoperability across diverse platforms and specialties.

Area of Science:

  • Health Informatics
  • Computer Science
  • Information Systems

Background:

  • Electronic Health Records (EHRs) are central to health information systems, requiring lifelong reliability, flexibility, and adaptability.
  • Current EHR systems face challenges in maintaining data integrity and interoperability over time.

Purpose of the Study:

  • To propose and evaluate an advanced EHR architecture for future-proof health information systems.
  • To ensure EHRs are communicable, comprehensive, useful, effective, and legally binding.
  • To develop EHRs that preserve data integrity independent of platforms, systems, and national specialties.

Main Methods:

  • The proposed EHR architecture is based on the ISO Reference Model-Open Distributed Processing.
  • A component-based paradigm of model-driven health information system architectures is utilized.
