Experiences with an interoperable data acquisition platform for multi-centric research networks based on HL7 CDA.

Area of Science:

• Medical Informatics
• Health Information Systems
• Clinical Research Technology

Background:

• Increasing medical specialization requires integrated telematic platforms for cross-institutional collaboration.
• Shared electronic patient records (EPRs) and secure remote data entry (RDE) are essential for collaborative clinical research and care.
• The German multicentric Epidermolysis Bullosa (EB) network needed a unified platform for data management.

Purpose of the Study:

• To develop and implement a shared remote data entry (RDE) platform for the German EB network.
• To facilitate cross-institutional cooperation and leverage the strengths of participating institutions.
• To support collaborative clinical research and patient care through a unified data storage system.

Main Methods:

• An existing telematic application was enhanced with an RDE module for structured data and pedigree storage.
• HL7 Clinical Document Architecture (CDA) was adopted as the standardized storage format for flexibility and interoperability.
• XML-based technologies were used to create adaptable data entry forms for distinct medical domains.

Main Results:

• A flexible and comprehensive EPR/RDE platform was successfully implemented within the German EB network.
• Specific data entry forms were developed to meet the network's comprehensive documentation requirements.
• The platform has been in productive use since 2005, demonstrating its reliability and utility.

Conclusions:

• Standardized documentation using HL7 CDA for EPRs enhances interoperability and integration of diverse healthcare systems.
• XML technologies provide significant flexibility and adaptability for various medical domains.
• Further development of standards like HL7 CDA R2 and interfaces can improve semantic and syntactic interoperability in healthcare data.
