The LUCY (Linked Ulm Care sYstem) project developed an Intensive Care Unit workstation for evaluating data processing and device integration. While accepted by staff, the system required significant resources and had limitations in flexibility and data redundancy.

Area of Science:

  • Biomedical Engineering
  • Clinical Informatics
  • Human-Computer Interaction

Background:

  • Intensive Care Units (ICUs) generate vast amounts of data from multiple devices.
  • Integrating and presenting this data effectively is crucial for patient care and research.
  • Existing systems often lack comprehensive integration and flexible evaluation capabilities.

Purpose of the Study:

  • To design and implement a research workstation in an ICU environment.
  • To evaluate data/information processing and presentation concepts.
  • To assess new devices and functions holistically within the entire workplace.

Main Methods:

  • Development of the Linked Ulm Care sYstem (LUCY) workstation.
  • Integration of patient monitor, ventilator, infusion pumps, and syringe pumps via serial interfaces.

  • Utilization of a high-performance graphic workstation for central data display.
  • Implementation of a versatile user interface with touch screen, keyboard, and mouse interaction.
  • Inclusion of a barcode-based system for fluid administration control and documentation.

    • Main Results:

    • The LUCY system was developed and tested in clinical routine.
    • Initial clinical experience showed good general acceptance of the workstation concept.
    • Analysis revealed 90% data redundancy, necessitating individual filtering algorithms for devices.
    • System flexibility for new features did not meet expectations.
    • Significant manpower (8 man-years) and cost ($160,000) were required.
    • Ongoing technical maintenance poses a challenge for current resources.

    Conclusions:

    • The LUCY project successfully created an integrated ICU research workstation.
    • The system demonstrates the need for advanced data filtering and highlights challenges in achieving desired flexibility.
    • Future iterations require careful consideration of development resources, maintenance, and adaptability for clinical informatics systems.
