This study presents a method to model and analyze dependencies between hospital business processes and communication system needs. The approach aids in systematic planning of health information systems (HIS).

Area of Science:

  • Health Informatics
  • Information Systems Engineering

Background:

  • Effective planning of hospital information systems (HIS) requires understanding the interplay between business processes and inter-system communication.
  • Existing approaches may not adequately capture these complex interdependencies.

Purpose of the Study:

  • To present an approach for modeling, visualizing, and analyzing the interdependencies between business processes and communication needs in HIS.
  • To ensure HIS architecture aligns directly with organizational business requirements.

Main Methods:

  • Utilized the 3LGM2 meta-model for describing health information systems.
  • Defined information processes as sequences of functions and communication paths as links between application system interfaces.
  • Applied the Floyd-Warshall algorithm to solve the all-pairs shortest-paths problem for identifying communication paths.

Main Results:

  • Developed an algorithm implemented within the 3LGM2 tool for interactive definition and analysis of information processes.
  • Enabled step-by-step analysis of communication infrastructure sufficiency at the logical tool layer.
  • Facilitated the direct association of HIS architecture with business needs.

Conclusions:

  • The approach effectively represents and analyzes dependencies between information processes and communication paths.
  • Provides a systematic method for planning HIS by linking technical infrastructure to business requirements.
  • Enhances the alignment of HIS architecture with critical business needs for improved hospital operations.
