This study introduces a novel expert system for rheumatological disorders, offering a dynamic differential diagnosis based on chief complaints. It enables faster, focused clinical decision-making compared to existing systems.

Area of Science:

  • Artificial Intelligence in Medicine
  • Clinical Decision Support Systems
  • Rheumatology

Background:

  • Existing expert systems like AI/Rheum lack dynamic differential diagnosis capabilities based on initial patient complaints.
  • Current systems may not offer immediate feedback on diagnostic certainty levels.

Purpose of the Study:

  • To design and demonstrate a Turbo Pascal prototype of an expert system for diagnosing rheumatological disorders.
  • To enable clinicians to input chief complaints for a dynamic differential diagnosis.
  • To provide immediate notification of diagnostic certainty (possible, probable, definite).

Main Methods:

  • Utilizes the AI/Rheum knowledge base for a directed workup.
  • Employs a physician-assisted hypothesis investigation approach, diverging from the Greek Oracle method.

  • Restricts questioning to relevant items for the dynamic differential diagnosis.

    • Main Results:

    • The prototype allows clinicians to enter chief complaints, generating a dynamic differential diagnosis.
    • The system provides immediate alerts when sufficient data is gathered for diagnosis at three predefined levels.
    • Fewer user interactions are required compared to AI/Rheum, despite a potentially longer interaction time due to the prototype interface.

    Conclusions:

    • The developed system offers a more rapid and focused approach to rheumatological diagnosis.
    • Future development aims to optimize knowledge base questioning and enhance disease exclusion capabilities.
    • The system represents a step towards more efficient and physician-centric clinical decision support.
