Abstract

A system and method for generating a medical history that is determined based on the patient'"'"'s medication list. Medications are taken for specific indications, i.e., disease and/or symptom, and the system includes a knowledge base of all known medications and associated indications. Preferably, an expert system allows the patient, nurse or other user, to enter all or part of the name of the patient'"'"'s medications, and creates a list of probable medications by determining which of the known medications the patient most likely takes. Based on a user selected probable medication, the system creates a list of probable medical indications associated with the selected medication. Based on a user selected probable indication, the system generates a medical history for the patient. The probable medications and probable medical indications are determined preferably based on the patient'"'"'s demographic data, historical data for other patients, and responses to follow-up questions generated by the system.

creating a list of probable medications using a computer processor, including determining which known medications are the probable medications that are more likely taken by the patient based on the at least a portion of the medication name received from the user, based on the patient'"'"'s demographic data and the historical data, and based on a first knowledge base of medications,

causing the list of probable medications to be displayed to the user; and

receiving a selection from the user of one of the probable medications on the list of probable medications;

for each one of the selected probable medications;

(i) creating a list of probable medical indications associated with the respective medication using a computer processor, wherein the probable medical indications are diseases or symptoms, including determining which known medical indications are probable medical indications for which the patient most likely takes the identified medication based on the patient'"'"'s demographic data and the historical data, and based on a second knowledge base of known medical indications for the respective medication;

(ii) causing the list of medical indications to be displayed to the user; and

(iii) receiving a selection from the user of one or more of the probable medical indications on the list; and

generating a medical history for the patient based on the user selected probable medical indications and respective medications.

2. The method of claim 1, wherein the historical data from other users of the method comprises data for other patients who match at least a portion of the demographic data of the patient.

3. The method of claim 1, further comprising ordering the list of probable medications starting with the known medications most likely taken by the patient.

4. The method of claim 1, wherein the list of probable medical indications is ordered from the most likely probable medical indications sequentially followed by less likely probable medical indications, with the most likely probable medical indications displayed at the top of the list.

10. The method of claim 1, wherein the determining is further based on historical data for the patient.

12. The method of claim 1, wherein the historical data from other users of the method includes inputs provided using the method.

13. The method of claim 1, wherein the demographic data includes at least one of the patient'"'"'s age, gender, diseases, and symptoms.

17. The method of claim 1, further comprising entering the generated medical history into an electronic medical record.

5. A method for generating a medical history for a patient, comprising:

obtaining from a user at least a portion of the names of each of the medications the patient is taking;

obtaining historical data for other patients who have used the method;

creating a list of probable medications using a computer processor, including determining which known medications are the probable medications that are more likely taken by the patient based on the at least a portion of the medication name received from the user, based on the historical data, and based on a first knowledge base of medications,

causing the list of probable medications to be displayed to the user; and

receiving a selection from the user of one of the probable medications on the list of probable medications;

for each one of the selected probable medications;

(i) creating a list of probable medical indications associated with the respective medication using a computer processor, wherein the probable medical indications are diseases or symptoms, including determining which known medical indications are probable medical indications for which the patient most likely takes the identified medication based on the historical data, and based on a second knowledge base of known medical indications for the respective medication;

(ii) causing the list of medical indications to be displayed to the user; and

(iii) receiving a selection from the user of one or more of the probable medical indications on the list; and

generating a medical history for the patient based on the user selected probable medical indications and respective medications.

6. The method of claim 5, wherein the historical data comprises historical data for other patients who match at least a portion of the demographic data of the patient.

7. The method of claim 5, further comprising:

selectively for each one of the selected probable medications, causing a question to be generated and to be displayed to the user, wherein the question is based at least on the selected probable medication, demographic data for the patient, and historical data for other patients from other users of the method.

8. The method of claim 7, wherein the list of probable medical indications displayed to the user includes ordering of the probable medical indications on the list based on a response received from the user to the question.

9. The method of claim 5, further comprising dynamically generating questions in response to previous responses received from the user, to generate additional information for inclusion in the patient'"'"'s medical history.

11. The method of claim 5, wherein the user selected probable medical indications and respective medications are provided in the medical history using widely accepted medical terminology.

14. The method of claim 5, wherein the list of medical indications is presented to the user using lay person terminology.

15. The method of claim 5, wherein the at least a portion of the name of the medication used by the patient comprises at least the first two letters of the name.

16. The method of claim 5, further comprising enabling secure viewing of the generated medical history via a network using password access.

18. The method of claim 5, wherein the medical history is generated via an expert system and machine learning.

19. The method of claim 5, further comprising

presenting one or more questions to the user regarding medical conditions, symptoms, and past surgical history for the patient for which the patient uses no medications;

and

wherein the medical history includes information based on user responses to the one or more questions.

20. The method of claim 5, wherein the step of obtaining from a user an identification of each of the medications the patient is taking comprises receiving input from the user of at least a portion of the name of each of the medications the patient is taking, and wherein the step of creating a list of probable medications further includes determining which known medications are the probable medications that are more likely taken by the patient based on the at least a portion of the medication name received from the user.

21. A system for generating an automated medical history of a patient, comprising:

a user interface for receiving from the user at least a portion of the names of each of the medications;

a first computer database for storing a library of known medications and their respective medical indications;

a second computer database for storing demographic data for the patient and a third database for storing historical data of other patients obtained through prior uses of the system;

a computer implemented expert system for creating a list of probable medications based on a determination of which known medications are probable medications based on the at least a portion of the medication name received from the user, based on the patient'"'"'s demographic data stored in the second database and the historical data stored in the third database, and based on the known medications in the first database;

wherein the user interface is further for causing the list of probable medications to be displayed to the user, and for receiving selection from the user of one of the probable medications from the list of probable medications;

the expert system is further for creating a list of probable medical indications associated with the selected probable medication based on a determination of which known medical indications are probable medical indications for which the patient most likely takes the selected medication using the known medications and their respective medical indications stored in the first database and based on the patient'"'"'s demographic data stored in the second database and the historical data stored in the third database;

the user interface is further for causing the list of probable medical indications to be displayed to the user and for receiving selection from the user one or more of the probable medical indications on the list of probable medical indications; and

wherein the expert system operative to generate a medical history for the patient that includes at least the selected probable medication and the selected one or more probable medical indications.
