An infrastructure for Integrated Electronic Health Record services: the role of XML (Extensible Markup Language)

Area of Science:

• Health Informatics
• Telemedicine
• Health Information Management

Background:

• Healthcare information resource sharing is crucial for improving productivity and care quality.
• Increasing population mobility necessitates national and international healthcare networks for information exchange.
• The HYGEIAnet regional health telematics network on Crete developed an Integrated Electronic Health Record (IEHR) environment for island-wide access to clinical information.

Purpose of the Study:

• To create a unified user interface for viewing comprehensive patient medical information.
• To integrate distributed and heterogeneous health record segments into a single IEHR.
• To provide on-line access to integrated patient data.

Main Methods:

• Implementation based on the HYGEIAnet Reference Architecture for service, component, and interface reuse.
• Utilized Extensible Markup Language (XML) for seamless information presentation.
• Enabled dynamic navigation based on user preferences and authorities.

Main Results:

• Developed an IEHR environment enabling consistent, authenticated Internet access to primary health information.
• Supported improved decision-making through readily available clinical data.
• Maintained primary information at its source, managed by the originating clinical information system, avoiding centralized repositories.

Conclusions:

• Extensible Markup Language (XML) offers a cost-effective technology for document accessibility, contingent on existing Healthcare Information Infrastructure.
• XML facilitates incremental implementation, transparent to end-users.
• The IEHR system provides a foundation for authenticated access to primary information, enhancing healthcare delivery.
