A component-based clinical information system (CIS) was successfully deployed at Georges Pompidou University Hospital (HEGP), proving high-performing and cost-effective. This approach facilitated the integration of essential healthcare functions and improved physician access to patient data.

Area of Science:

  • Health Informatics
  • Computer Science in Medicine

Background:

  • The Georges Pompidou University Hospital (HEGP) was established by merging three older facilities, necessitating a new, integrated clinical information system (CIS).
  • A component-based architecture was chosen to build the HEGP CIS, aiming for flexibility and efficiency.

Purpose of the Study:

  • To describe the selection process for business components of the HEGP CIS.
  • To outline the main functions of the deployed CIS and its technical infrastructure.
  • To evaluate the performance and cost-effectiveness of the component-based approach for CIS development.

Main Methods:

  • The HEGP CIS was developed using a component-based approach, integrating generic components (e.g., document manager, security manager) and healthcare-specific components (e.g., patient record, act management).

  • Key functions were made operational at the hospital's opening, with subsequent deployment and user adoption monitored.
  • The system included a unique patient record, provider order entry, and online access to investigation results and images.

    • Main Results:

    • Major CIS functions were operational upon HEGP's opening in July 2000.
    • Within two years, the unique patient record and provider order entry system achieved 96% adoption in relevant units.
    • Physician direct entry of biological and imaging orders reached 65% and 55% respectively, with 100% of units utilizing online access to investigation results and images.

    Conclusions:

    • The component-based approach proved to be a high-performing and cost-effective strategy for designing and deploying the HEGP CIS.
    • The successful implementation demonstrates the viability of this architecture for modern hospital information systems.
