Abstract

The present invention is designed to develop research protocols for clinical trials. The invention also can track and enhance subject compliance with a research protocol. The invention further provides evaluability data related to subject performance in the clinical trial. According to an alternative embodiment of the invention, a portable electronic device is used to query and collect data from the subject.

5. The method of claim 4, wherein the quantitative analysis comprises a statistical or data mining technique.

6. The method of claim 5, wherein the statistical or data mining technique comprises logistic regression, discriminant function analysis, classification and regression trees, neural networks, or multiple linear regression.

7. The method of claim 1, wherein the one or more evaluability data categories comprise timeliness of data entry and another category.

8. The method of claim 7, wherein the another category comprises consistency with other collected data, proximity of the data to an expected data range, or completeness of the data.

9. The method of claim 1, wherein the comparing the evaluability data occurs during the clinical trial.

10. The method of claim 1, further comprising generating at least one compliance enhancing feature.

11. The method of claim 10, wherein the at least one compliance enhancing feature comprises a question to be posed to a user to determine a reason for non-compliance, an alarm tone, or a delay in reporting.

12. The method of claim 1, wherein the norm is a historic norm.

13. The method of claim 1, wherein the norm is a population norm.

14. The method of claim 1, further comprising gathering the evaluability data in an evaluability database.

15. The method of claim 14, wherein the evaluability database is a disease-specific database.

16. The method of claim 14, wherein the evaluability database is a population-specific database.

17. The method of claim 14, wherein the evaluability database is adapted to store data related to subject compliance.

18. The method of claim 1, wherein the electronic device is a workstation.

19. The method of claim 1, wherein the electronic device is a handheld electronic device.

20. The method of claim 19, wherein the handheld electronic device is a handheld portable computer or phone.

21. The method of claim 1, wherein the electronic device is connected to the Internet.

22. A computer readable medium having stored thereon sequences of instructions, which, when executed by a computer system, cause the computer system to perform:

a. electronically accessing evaluability data obtained during a clinical trial, wherein the evaluability data is from one or more participants in the clinical trial, wherein the evaluability data is stored on an electronic device, wherein the evaluability data comprise data from one or more evaluability data categories;

b. comparing the evaluability data from the one or more evaluability data categories to a norm to classify clinical trial results from the one or more participants in the clinical trial based on a type of compliance; and

c. analyzing the classified clinical trial results from the one or more participants with a similar type of compliance.

23. The computer readable medium of claim 22, wherein the type of compliance comprises good compliance, non-compliance, or minor non-compliance.

24. The computer readable medium of claim 22, wherein the one or more evaluability data categories are used to determine a desirability of retaining the one or more participants in the trial or incorporating the evaluability data from the one or more participants in the trial results.

25. The computer readable medium of claim 22, wherein the comparing comprises a quantitative analysis.

26. The computer readable medium of claim 25, wherein the quantitative analysis comprises a statistical or data mining technique.

27. The computer readable medium of claim 26, wherein the statistical or data mining technique comprises logistic regression, discriminant function analysis, classification and regression trees, neural networks, or multiple linear regression.

28. The computer readable medium of claim 22, wherein the one or more evaluability data categories comprise timeliness of data entry and another category.

29. The computer readable medium of claim 28, wherein the another category comprises consistency with other collected data, proximity of the data to an expected data range, or completeness of the data.
