Abstract

An online medical evaluation and treatment system includes a patient interface, a physician interface and diagnostic tools to gather and sort information sent from the patient and automatically generate candidate diagnoses. A patient enters information about a medical condition through the patient interface. The diagnostic tools evaluate the information provided by the patient, generate further questions, and create a list of possible diagnoses known as a differential diagnosis. A physician enters the physician interface to review a patient file and diagnose the medical condition of the patient. Importantly, the physician does not have to be present as the data is gathered from the patient, thus saving the physician time. The information gathered from the patient may also be exported to external databases for processing by a third party.

Claims

1. A medical diagnostic system comprising:

a server configured to present to a patient through a browser interface at a remote location a list of symptoms and risk factors and to retrieve through said interface found symptoms and found risk factors that the patient has selected from said list;

the server being further configured to calculate from said found symptoms and said found risk factors a likelihood that the patient has said ailment; and

the server being further configured to enable a designated authority to set, through a browser interface at a remote location, which symptoms and risk factors the server will present to the patient and to set parameters that the server will use in calculating said likelihood that the patient has the ailment.

2. The system of claim 1, wherein said parameters include, for each of said presented symptoms, an importance value that correlates said symptom with said ailment and that is selected from a set of discrete possible importance values, and wherein said calculating includes generating a found distribution of the number of found symptoms having each possible importance value.

3. The system of claim 2, wherein said calculating further includes determining a suspicion index as a function of said found distribution.

4. The system of claim 3, wherein said suspicion index is determined by comparing said found distribution to a set of threshold distributions to determine for which of said threshold distributions each count in said found distribution meets or exceeds the corresponding count in the threshold distribution.

5. The system of claim 1, wherein said parameters include, for each of said presented risk factors, a risk index that correlates that risk factor with said ailment, and wherein said calculating includes determining said likelihood as a function of the risk indexes of said found risk factors.

6. The system of claim 1, wherein said risk factors include zipcodes, occupations and preexisting medical conditions.

7. The system of claim 1, configured to present said risk factors to the patient only if and only after said found symptoms are received by the server and are found to indicate more than a threshold level of suspicion of the patient having said ailment.

8. The system of claim 1, further configured to instruct the patient to perform a specific action based on the level of said likelihood.

9. A process comprising:

compiling a list of symptoms related to an ailment;

compiling a list of discrete possible importance values;

assigning, to each of said symptoms, one of said possible importance values that correlates said symptom to said ailment;

presenting said list of symptoms to a patient;

receiving from the patient found symptoms that the patient has selected from said list;

generating a distribution of the number of found symptoms having each possible importance value; and

determining a suspicion index as a function of said distribution.

10. The process of claim 9, wherein the determining step includes comparing said distribution to a set of threshold distributions.

11. The process of claim 9, wherein the presenting steps and the receiving step are performed by a web server communicating with the patient through a browser interface over the Internet.

12. The process of claim 9, wherein the compiling steps and the assigning step are performed by a web server communicating with a designated authority through a browser interface.

13. The process of claim 9, further including the steps of compiling a list of risk factors related to an ailment, presenting said list of risk factors to the patient, receiving from the patient found risk factors that the patient has selected from said list, and determining a likelihood of the patient having said ailment as a function of said suspicion index and said found risk factors.

14. The process of claim 13, wherein said risk factors include zipcodes, occupations and preexisting medical conditions.

15. A process comprising:

presenting a list of symptoms to a patient that are related to a specific ailment;

receiving from the patient found symptoms that the patient has selected from said list;

calculating a suspicion index for said ailment from said found symptoms;

presenting a list of risk factors to the patient that are related to said ailment;

receiving from the patient found risk factors that the patient has selected from said list; and

calculating an overall risk index for said ailment from said found risk factors;

said second presenting step being performed only if and only after determining that said suspicion index meets or exceeds a threshold value.

16. The process of claim 15, wherein said risk factors include zipcodes, occupations and preexisting medical conditions.

17. The process of claim 15, wherein said presenting and receiving steps are performed by a server through a browser interface remote from the server.

18. The process of claim 15, further comprising calculating a likelihood of said ailment as a function of said suspicion index and said overall risk index;

19. The process of claim 18, further comprising instructing the patient to perform a specific action based on the level of said likelihood.
