Abstract

The present invention is a system and method for anticipating potential Adverse Drug Events (ADE) in a patient'"'"'s medication regimen by integrating data typically located in laboratory and pharmacy information systems and filtering the data using predefined criteria. The present invention includes a system for anticipating a possible ADE through the use of a search engine that compares integrated data from laboratory and pharmacy information systems and compares it to predefined ADE rules defining normal ranges for a particular laboratory test. If an abnormal test value is received and a drug in the patient'"'"'s medication regimen satisfies a drug included in an ADE rule then an alert procedure is triggered which allows for a period of time wherein the patient'"'"'s lab and pharmacy data is monitored in order to determine if a proper corrective action is undertaken, and if no corrective action or an improper corrective action is taken within that period of time, the healthcare provider is warned of a potential ADE.

Claims

1. A method of anticipating adverse drug episodes comprising:

defining a plurality of ADE rules having data fields for a lab test name, a value for the lab test, and a drug; and

filtering a patient'"'"'s lab data and pharmacy data using the plurality of definitions.

2. The method of claim 1, and further comprising the additional step of creating a normalized drug table from a patient'"'"'s pharmacy data, the pharmacy table having data fields for each drug administered, a dosage, and a time administered.

3. The method of claim 2, and further comprising the additional step of creating a normalized lab table from a patient'"'"'s lab data, the lab table having data fields for a patient id, time of test, name of test, and a test result.

4. The method of claim 3, wherein the step of filtering includes the steps of extracting a lab name, a result of the lab from the lab table and a drug from the drug table and matching it to a lab name, lab result and drug within an ADE rule.

5. The method of claim 1, and further comprising the additional step of importing laboratory data and pharmacy data from a healthcare facility.

6. The method of claim 5, and further comprising the additional step of verifying imported lab data or pharmacy data is formatted in accordance with a predefined format.

7. The method of claim 1, and further comprising the additional steps of computing a cumulative dosage for a drug within a 24 hour period from a date of administration.

8. The method of claim 1, wherein the ADE rules also includes a data field containing a waiting period for a proper corrective action.

9. The method of claim 8, and further comprising the additional steps of filtering subsequent lab data or pharmacy data to determine if a proper corrective action has occurred.

10. The method of claim 9, and further comprising the additional step of alerting a health care provider when a waiting period for a proper corrective action has expired without a proper corrective action occurring.

11. The method of claim 8, and further comprising the additional step of adjusting a waiting period based on a test lab value.

12. The method of claim 8 and further comprising the additional step of adjusting a waiting period based on previous lab test values.

13. The method of claim 1, wherein the lab/data definition includes data fields for associated drugs.

14. The method of claim 13, further comprising the additional step of filtering a patient'"'"'s previous pharmacy data for an associated drug.

15. The method of claim 1, wherein the lab/data definition includes data fields for an associated test lab and result.

16. The method of claim 15, further comprising the additional step of filtering a patient'"'"'s lab data for an associated test lab and result.

17. A system for anticipating adverse drug events comprising:

a central processor having a search engine therein; and

an ADE rule database in communication with the server.

18. The system of claim 17, wherein the central processor is in communication with a computer network.

19. The system of claim 18, wherein the computer network. is an intranet.

20. The system of claim 17, and further comprising a laboratory and a pharmacy database.

21. The system of claim 17, wherein the central processor includes a web server hosting a web site therein and in communication with an intranet.

22. The system of claim 17, wherein the central processor is in communication with a pharmacy information system and a laboratory information system.

23. The system of claim 17, wherein the central processor is in communication with a nursing station at a medical facility.

24. The system of claim 17, wherein the central processor is in communication with a paging system.

25. The system of claim 17, wherein the central processor includes a web server, an application server, a database server, and a directory server.

26. The system of claim 17 wherein the central processor includes an application for reformatting and integrating pharmacy data and lab data.

27. A method of anticipating adverse drug episodes comprising:

defining a plurality of ADE rules having data fields for a lab test name, a value for the lab test, and a drug;

storing the ADE rules within an ADE rules database;

importing a patient'"'"'s lab data and pharmacy data;

storing a patient'"'"'s lab result, the lab test name, and a name of a drug administered to the patient within a database;

matching a patient'"'"'s lab result, test name, and administered drug with a lab value, lab name and drug within an ADE rule.

28. The method of claim 27, and further comprising the additional steps of extracting a lab test name, a lab test result from a patient'"'"'s lab data and extracting a drug name from a patient'"'"'s pharmacy data.

29. The method of claim 27, wherein the step of storing includes the steps of storing a patient'"'"'s lab result and the lab test name within a lab database and storing a name of a drug administered within a pharmacy database.

30. The method of claim 27, and further comprising the additional steps alerting a health care provider when a match occurs.

31. The method of claim 27, and further comprising the additional step of storing a patient'"'"'s hospital unit, doctor, diagnosis, gender, and age within a database.

32. The method of claim 31, wherein the ADE rule includes a data field for storing a hospital unit, doctor, diagnosis, gender, and age.

33. The method of claim 32, and further comprising the additional steps of matching a patient'"'"'s hospital unit, doctor, diagnosis, gender, and age with a respective value in an ADE rule.
