Integrating legacy systems into clinical workstations is crucial for hospitals. This approach offers flexible encapsulation, avoiding costly reengineering of existing proprietary technology.

Area of Science:

  • Health Informatics
  • Computer Science
  • Information Systems

Background:

  • Hospitals extensively use proprietary legacy systems.
  • Implementing new technology requires integrating these existing systems.
  • Reengineering legacy systems is often economically and organizationally unfeasible.

Purpose of the Study:

  • To describe methods for integrating legacy systems into clinical workstations.
  • To present challenges and solutions for legacy system integration.
  • To outline features for effective clinical workstation integration.

Main Methods:

  • Describing input/output and translation models for legacy system integration.
  • Presenting case studies of legacy systems integrated into the HERMES clinical workstation.

Related Experiment Videos

  • Analyzing features required for a comprehensive clinical workstation.

    • Main Results:
