    This study presents a reliable, general-use algorithm for medical diagnosis assistance. It efficiently compares patient symptoms against a hierarchically organized disease matrix for faster differential diagnosis.

    Area of Science:

    • Medical Informatics
    • Artificial Intelligence in Medicine
    • Clinical Decision Support Systems

    Background:

    • Accurate and timely medical diagnosis is crucial for effective patient treatment.
    • Traditional diagnostic methods can be time-consuming and prone to error.
    • Developing automated diagnostic tools can enhance healthcare efficiency and accuracy.

    Purpose of the Study:

    • To design and present a novel algorithm for assisting medical diagnosis.
    • To create a highly reliable and generally applicable diagnostic support system.
    • To improve the efficiency of differential diagnosis processes.

    Main Methods:

    • The algorithm utilizes a matrix-based approach, organizing disease symptoms hierarchically.
    • It compares a patient's symptom vector against columns of disease symptoms within this matrix.
