Abstract

A computerized method for evaluating medical reports includes identifying at least one or more medical reports stored in a database related to the medical condition, validating the identified medical reports by determining if key words associated with the medical condition found in the at least one or more reports are surrounded by a negative context and extracting relevant data from the medical reports. The exemplary method also includes evaluating the relevant data from the medical reports with provisions set forth in clinical guidelines corresponding to a medical condition, storing a flag identifying one or more of the medical reports as noncompliant when its corresponding relevant data does not comply with the provisions set forth in the clinical guideline unless a valid contraindication applies and displaying the medical reports identified as noncompliant.

Claims

1. A method for evaluating medical reports to determine whether care administered to patients adheres to clinical guidelines for a medical condition, comprising:

identifying at least one or more medical reports stored in a database related to the medical condition;

validating the identified medical reports by determining if key words associated with the medical condition found in the at least one or more reports are surrounded by a negative context;

extracting relevant data from the medical reports;

evaluating the relevant data from the medical reports with provisions set forth in the clinical guidelines corresponding to the medical condition;

storing a flag identifying one or more of the medical reports as noncompliant when its corresponding relevant data does not comply with the provisions set forth in the clinical guideline unless a valid contraindication applies; and

displaying the medical reports identified as noncompliant.

2. The method of claim 1, wherein the step of evaluating comprises, comparing the relevant data with the provisions using natural language processing techniques embedded in an extensible markup language (XML) framework.

3. The method of claim 1, wherein the clinical guideline is represented in an extensible markup language (XML) framework.

4. The method of claim 1, wherein a contraindication is a condition requiring deviation from the provisions set forth in the clinical guideline.

5. The method of claim 1, wherein the step of displaying comprises providing a user with display options for displaying the medical reports.

6. The method of claim 5, wherein the display options comprises i) displaying the noncompliant medical reports, or ii) displaying all of the medical reports with an associated tag indicating whether the medical report is noncompliant or not.

7. A computer program product comprising at least one computer-readable storage medium having computer-readable program code portions stored therein for evaluating medical reports to determine whether care administered to patients adheres to clinical guidelines for a medical condition, the computer-readable program code portions comprising:

a first executable portion for identifying at least one or more medical reports relating to the medical condition;

a second executable portion for validating the identified medical reports by determining if key words associated with the medical condition found in the at least one or more reports are surrounded by a negative context;

a third executable portion for extracting relevant data from the medical reports;

a fourth executable portion for evaluating the relevant data from each report with provisions set forth in the clinical guidelines corresponding to the medical condition; and

a fifth executable portion for storing a flag identifying one or more of the medical reports as noncompliant when its corresponding relevant data does not comply with the provisions set forth in the clinical guideline unless a valid contraindication applies; and

a sixth executable portion for causing the medical reports identified as noncompliant to be displayed.

8. The computer program product of claim 7, wherein the fourth executable portion comprises comparing the relevant data with the provisions using natural language processing techniques embedded in an extensible markup language (XML) framework.

9. The computer program product of claim 7, wherein the clinical guideline is represented in an extensible markup language (XML) framework.

10. The computer program product of claim 7, wherein a contraindication is a condition requiring deviation from the provisions set forth in the clinical guideline.

11. The computer program product of claim 7, wherein the step of causing the medical reports to be displayed comprises providing an user with display options for displaying the medical reports.

12. The computer program product of claim 11, wherein the display options comprises i) displaying the noncompliant medical reports, or ii) displaying all of the medical reports with an associated tag indicating whether the medical report is noncompliant or not.

13. A method of determining patient medical conditions by evaluating data in medical reports, comprising:

searching data in medical reports stored in a storage device using a selected group of words to identify at least one or more concepts;

extracting data from medical reports stored in a storage device;

determining the context of the identified concept;

tagging identified concepts with a qualifier to characterize the context of the concept;

applying a set of rules to the data to determine medical conditions when a concept has not been identified;

determining the medical condition based on the results of searching, determining and tagging or based on the result of application of the rules; and

displaying the medical condition and the medical report as the result.

14. The method of claim 13, wherein the context of the identified concept is determined by searching for selected words used to establish the context of the concept within a sentence fragment of any of the selected group of words.

15. The method of claim 13, wherein a concept is represented as a collection of terms which are synonymous with a medical condition.

16. The method of claim 13, wherein a qualifier is any one of negated, hypothetical, historical, pertaining to relatives of patient, or natively true in the current time frame.

17. The method of claim 13, wherein the medical report is a discharge summary.
