Developing a flexible clinical workstation architecture using distributed object-oriented services enhances software reusability. This approach supports various user interfaces and database tiers for ambulatory care applications.

Area of Science:

  • Computer Science
  • Health Informatics
  • Software Engineering

Background:

  • Clinical applications often struggle with software reusability, leading to integration challenges with legacy systems.
  • Developing adaptable architectural frameworks is crucial for modernizing healthcare software.

Purpose of the Study:

  • To present a novel architectural framework for clinical workstation applications.
  • To demonstrate how a distributed object-oriented services middle tier enhances flexibility and reusability.

Main Methods:

  • Designed a clinical workstation architecture centered on a middle tier of distributed object-oriented services.
  • Implemented core services for vocabulary, patient index, documents, charting, security, and encounter management.
  • Utilized standard distributed object interfaces (CORBA, OLE) for service implementation.

Main Results:

  • The architecture facilitated the creation of flexible user interface and database tiers.
  • Core services were successfully reused across multiple applications, including World Wide Web browser interfaces.
  • The framework supported a mix-and-match approach for user interface components.

Conclusions:

  • A distributed object-oriented services architecture promotes significant software reusability in clinical applications.
  • This architectural approach offers flexibility for developing diverse clinical workstation interfaces and integrating with various systems.
  • The model is adaptable for both new development and the integration of legacy systems.
