Surgical residents can now access patient lab results faster using the ScroungeMaster mobile system. This pen-based interface in the intensive care unit (ICU) improves data readability and physician workflow.

Area of Science:

  • Medical Informatics
  • Clinical Software Development
  • Surgical Care

Background:

  • Surgical residents require significant time (approx. 30 minutes) multiple times daily to access patient lab values in the intensive care unit (ICU).
  • Existing systems present challenges in data readability and timeliness for critical care decision-making.

Purpose of the Study:

  • To develop and evaluate a mobile, pen-based software system to streamline access to laboratory results for surgical residents in the ICU.
  • To reduce the time spent retrieving patient data and enhance its presentation.

Main Methods:

  • Developed the ScroungeMaster system on a portable tablet computer with a local database cache.
  • Implemented a background task for rapid cache updates (approx. 2.7 minutes) and a user interface organizing lab results by physiologic system.

  • Utilized a layout selection algorithm based on access history, physician preferences, and patient condition.

    • Main Results:

    • Physicians expressed a preference for the ScroungeMaster interface over existing systems.
    • The system demonstrated satisfactory performance in delivering timely and readable lab results.
    • Observed positive changes in physician workflow due to mobile, pen-based computing in the ICU.

    Conclusions:

    • The ScroungeMaster system effectively reduces time spent accessing ICU lab results for surgical residents.
    • Mobile, pen-based computing can significantly improve information delivery and physician workflow in critical care settings.
    • Physician satisfaction and preference indicate the value of user-centered design in clinical software.
