Summary
This study evaluates middleware approaches like CORBA, DHE, and Health Level Seven (HL7) for healthcare systems integration. It highlights HL7
Area of Science:
- Health Informatics
- Computer Science
- Information Systems
Background:
- Healthcare enterprises require robust middleware for seamless systems integration.
- Existing middleware solutions present diverse architectural frameworks and conceptual underpinnings.
- Evaluating these approaches is crucial for optimizing healthcare IT infrastructure.
Purpose of the Study:
- To describe and evaluate different middleware approaches for healthcare systems integration.
- To compare CORBA, DHE, and HL7 based on their concepts, architecture, and enterprise relevance.
- To provide recommendations for future middleware development in healthcare.
Main Methods:
- Comparative analysis of middleware technologies: CORBA, DHE, and HL7.
- Evaluation based on conceptual models and architectural frameworks.
- Assessment of relevance for healthcare enterprises and electronic patient records.
Main Results:
- CORBA is a strictly object-oriented approach, promoted by CORBAmed.
- DHE is based on process-related concepts.
- HL7 is evolving towards a harmonized information interchange concept, supporting electronic patient records and EDI standards migration.
Conclusions:
- Middleware selection significantly impacts healthcare systems integration.
- HL7's evolution offers enhanced flexibility and interoperability for healthcare information exchange.
- Future developments should focus on standardized platforms and networking mediator applications for improved integration.
