Abstract

A system and method for providing computerized, knowledge-based medical diagnostic and treatment advice. The medical advice is provided to the general public over a telephone network. Two new authoring languages, interactive voice response and speech recognition are used to enable expert and general practitioner knowledge to be encoded for access by the public. “Meta” functions for time-density analysis of a number of factors regarding the number of medical complaints per unit of time are an integral part of the system. A semantic discrepancy evaluator routine along with a mental status examination are used to detect the consciousness level of a user of the system. A re-enter feature monitors the user'"'"'s changing condition over time. A symptom severity analysis helps to respond to the changing conditions. System sensitivity factors may be changed at a global level or other levels to adjust the system advice as necessary.

Claims

1. A computerized medical diagnostic system comprising:

a memory configured to store a data structure, wherein data in the data structure can be referenced by specification of a plurality of attributes representative of a medical condition of a patient,

wherein a first attribute corresponds to a cause of disease and a second attribute corresponds to an anatomic system; and

a processor, in data communication with the memory, configured to make a diagnosis based on the data in the data structure.

2. The system of claim 1, wherein the diagnosis is a single disease.

3. The system of claim 1, wherein the diagnosis is a differential diagnosis list.

4. The system of claim 1, wherein each cause of disease is subdivided into subcauses of disease.

5. The system of claim 1, wherein each anatomic system is subdivided into anatomic subsystems.

6. The system of claim 1, wherein a third attribute is time.

7. The system of claim 1, wherein the data structure is a two-dimensional array.

8. The system of claim 1, wherein the data structure is a three-dimensional cube.

9. A computerized method of medical diagnosis, the method comprising:

ascertaining a plurality of attributes of a medical condition of a patient, wherein a first attribute is associated with a cause of disease and a second attribute is associated with an anatomic system;

modifying a data structure based on the attributes; and

diagnosing the medical condition of a patient based on the data structure.

10. A computerized method of medical diagnosis, the method comprising:

associating a data structure, stored in a memory on a computer, with a patient, wherein data in the data structure can be referenced by specification of a plurality of attributes representative of a medical condition of the patient, wherein a first attribute corresponds to a cause of disease and a second attribute corresponds to an anatomic system;

ascertaining a plurality of attributes of a first medical condition of the patient;

modifying the stored data structure based on the plurality of attributes of the first medical condition;

ascertaining a plurality of attributes of a second medical condition of the patient;

modifying the stored data structure based on the plurality of attributes of the second medical condition; and

outputting a diagnosis based on the data in the data structure.

11. The method of claim 10, wherein the diagnosis comprises a third medical condition.

12. The method of claim 10, wherein a third attribute corresponds to time.

13. The method of claim 10, wherein the first medical condition and second medical condition are the same medical condition.

14. The method of claim 10, wherein the first medical condition and second medical condition are associated with different times.

15. The method of claim 10, wherein each cause of disease is subdivided into subcauses of disease.

16. The method of claim 10, wherein each anatomic system is subdivided into anatomic subsystems.

17. A computer usable medium having computer readable program code embodied therein for performing a computerized process used in medical diagnosis, the computer readable code comprising instructions for:

associating a data structure, stored in a memory on a computer with a patient, wherein data in the data structure can be referenced by specification of a plurality of attributes representative of a medical condition of the patient, wherein a first attribute corresponds to a cause of disease and a second attribute corresponds to an anatomic system;

ascertaining a plurality of attributes of a first medical condition of the patient;

modifying the stored data structure based on the plurality of attributes of the first medical condition;

ascertaining a plurality of attributes of a second medical condition of the patient;

modifying the stored data structure based on the plurality of attributes of the second medical condition; and

outputting a diagnosis based on the data in the data structure.

18. A computerized medical diagnostic system comprising:

means for associating a data structure, stored in a memory on a computer, with a patient, wherein data in the data structure can be referenced by specification of a plurality of attributes representative of a medical condition of the patient, wherein a first attribute corresponds to a cause of disease and a second attribute corresponds to an anatomic system;

means for ascertaining a plurality of attributes of a first medical condition of the patient;

means for modifying the stored data structure based on the plurality of attributes of the first medical condition;

means for ascertaining a plurality of attributes of a second medical condition of the patient;

means for modifying the stored data structure based on the plurality of attributes of the second medical condition; and

means for outputting a diagnosis based on the data in the data structure.

19. The system of claim 18, wherein the means for outputting comprises a modem.

20. The system of claim 18, wherein the means for outputting comprises a monitor, a telephone, or a speaker.

21. The method of claim 18, wherein the first medical condition and second medical condition are the same medical condition.
