Automated diagnostic system and method including alternative symptoms
First Claim
1. A method of automated medical diagnosis of a patient, the method comprising:
- a) evaluating symptom elements for the patient from a first set of symptom elements;
b) switching to evaluate symptom elements from a second set of symptom elements for a selected disease when a condition is satisfied;
c) reevaluating the previously evaluated symptom elements from the first set of symptom elements with corresponding symptom elements from the second set of symptom elements for the selected disease; and
d) automatically diagnosing a medical problem of the patient based on the evaluating and reevaluating of the symptom elements.

Abstract
Structure-based processing includes a method of diagnosing diseases that works by arranging diseases, symptoms, and questions into a set of related disease, symptom, and question structures, such as objects or lists, in such a way that the structures can be processed to generate a dialogue with a patient. A structure-based processing system organizes medical knowledge into formal structures and then executes those structures on a structure engine to automatically select the next question. Patient responses to the questions lead to more questions and ultimately to a diagnosis. An object-oriented embodiment includes software objects utilized as active, intelligent agents where each object performs its own tasks and calls upon other objects to perform their tasks at the appropriate time to arrive at a diagnosis. Alternative symptoms, synergies, encoding of patient responses, multiple diagnostic modes, disease profiles or timelines, and the reuse of diagnostic objects enhance the processing of the system and method.

10. A system for automated medical diagnosis of a patient, the system comprising:
-
(a) a first function configured to select a disease applicable to the patient;
(b) a second function configured to select a symptom associated with the selected disease;
(c) a third function configured to automatically determine, for the selected disease, if the selected symptom has an alternative symptom that has already been evaluated;
(d) a fourth function configured to apply a diagnostic weight of the alternative symptom to a diagnostic score associated with the selected disease; and
(e) a fifth function configured to automatically determine if a diagnosis of the disease has been reached based on the diagnostic score after application of the weight. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
