Abstract

A system for providing computerized, knowledge-based medical diagnostic and treatment advice. The medical advice is provided to the general public over a digital network via interactive dialogue. Software 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 dynamic data structure is used to record and save new patient data 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 system for medical self-diagnosis, the system comprising:

a memory in data communication with a computing device, said memory configured to store;

a static medical history objects data structure, said static medical history objects data structure comprising a specification of a plurality of attributes representative of at least one of;

a symptom of at least one disease,

an attribute of the at least one disease, and

an anticipated rate of change in severity of the at least one disease, the anticipated rate of change including a set threshold,

a modifiable data structure, said modifiable data structure comprising specifications of a plurality of attributes representative of at least one of;

a medical history of a patient,

a consultation history of the patient, and

a patient input concerning a present symptom of the patient,

a processor in data communication with said computing device, the processor configured to;

receive the patient input, without physician assistance, via a direct interactive dialogue between the patient and the computing device;

store the patient input in the modifiable data structure;

specifically respond to the patient based on said modifiable data structure;

access the static medical history objects data structure;

determine an actual rate of change in severity of the at least one disease;

transmit a self-diagnosis to the patient, the self-diagnosis based on the patient input, the data in the static medical history objects data structure and the data in the modifiable data structure; and

transmit, to the patient via said direct interactive dialogue, an action to take if said actual rate of change in severity exceeds said set threshold;

wherein said modifiable data structure is modified by the direct interactive dialogue and said static medical history objects data structure remains unchanged by the direct interactive dialogue.

2. The computerized system for medical self-diagnosis of claim 1, wherein the static medical history objects data structure is changed only by a system administrator outside of said direct interactive dialogue.

3. The computerized system for medical self-diagnosis of claim 1, wherein the symptom of the at least one disease further includes a symptom severity.

4. The computerized system for medical self-diagnosis of claim 1, wherein the symptom of the at least one disease further includes a symptom severity trend.

5. The computerized system for medical self-diagnosis of claim 1, wherein the direct interactive dialogue between the patient and the computing device further includes at least one of voice communication, data communication, or third party assistance.

6. A method for computerized medical self-diagnosis, the method comprising:

receiving, without physician assistance, an input from a patient concerning a present symptom of the patient via a direct interactive dialogue between the patient and a computing device;

storing, in a static medical history objects data structure in data communication with said computing device, a plurality of attributes representative of at least one of;

a symptom of at least one disease,

an attribute of the at least one disease, and

an anticipated rate of change in severity of the at least one disease, the anticipated rate of change including a set threshold,

storing, in a modifiable data structure in data communication with said computing device, a plurality of attributes representative of at least one of;

a medical history of a patient,

a consultation history of the patient, and

the input from the patient,

modifying said modifiable data structure in said computing device based on said direct interactive dialogue;

responding to the patient via said direct interactive dialogue, based on said modifiable data structure;

determining an actual rate of change in severity of said at least one disease;

transmitting, to the patient via said direct interactive dialogue, an action to take if said actual rate of change in severity exceeds said set threshold; and

transmitting a self-diagnosis to the patient via said direct interactive dialogue, the self-diagnosis based on the input from the patient, the data in the static medical history objects data structure and the data in the modifiable data structure.

7. The method for computerized medical self-diagnosis of claim 6, wherein the static medical history objects data structure is changed only by a system administrator outside of said direct interactive dialogue.

8. The method for computerized medical self-diagnosis of claim 6, wherein the symptom of the at least one disease further includes a symptom severity.

9. The method for computerized medical self-diagnosis of claim 6, wherein the symptom of the at least one disease further includes a symptom severity trend.

10. The method for computerized medical self-diagnosis of claim 6, wherein the direct interactive dialogue between the patient and the computing device further includes at least one of voice communication, data communication, or third party assistance.
