Automated diagnostic system and method
View Patent ↗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.

26. The system of claim 25 , wherein the patient health item comprises a problem, symptom, manifestation, test result, or observed effect.
27. The system of claim 25 , wherein, when the symptom object is executed by the processor, the symptom object manipulates data related to the patient's habits or environment.
28. The system of claim 25 , wherein, when the symptom object is executed by the processor, the symptom object evaluates changes in the severity of the patient health item over time.
29. The system of claim 25 , wherein the symptom object comprises a code for use in managing a disease identified by the determined diagnosis.
30. The system of claim 1 , wherein when the objects are executed by the processor, the objects interact to provide advice regarding a treatment for the patient.
31. The system of claim 30 , wherein the treatment comprises counseling, intervention, rehabilitation, or therapy.
32. An automated diagnostic system for use in a computing environment, the system comprising:
