A reference architecture for integrated EHR in Colombia

Area of Science:

• Health Informatics
• Computer Science
• Information Systems

Background:

• National electronic health record (EHR) infrastructures require well-defined system architectures.
• Architectures must be open, scalable, flexible, user-friendly, trustworthy, and standards-based.

Purpose of the Study:

• To propose a reference architecture for implementing an integrated EHR system in Colombia.
• To leverage existing architectural models and EHR standards for semantic interoperability.

Main Methods:

• Utilized the General Computerized Model (GCM) as an architectural framework.
• Defined a set of services and interfaces for clinical document exchange.
• Tested the proposed architecture in a pilot tele-consultation project.

Main Results:

• Developed an open, scalable, flexible, and semantically interoperable EHR infrastructure.
• Successfully exchanged dental EHRs in a pilot tele-consultation setting in Colombia.

Conclusions:

• The proposed reference architecture provides a viable model for integrated EHR implementation in Colombia.
• The architecture supports seamless exchange of clinical documents, enhancing healthcare interoperability.
