Abstract

A device for monitoring subject compliance comprising an instrumented paper diary for subjects to record clinical trial data. The instrumented paper diary creates an objective record of the use of the diary to verify subject entries, allowing researchers and clinicians to systematically track the use of the diary in the field. Subjects record clinical trial data in a paper diary. Electronic instrumentation connected to the paper diary allows use of the diary (e.g. when it was opened and closed) to be unobtrusively tracked, recorded and evaluated against how research protocols dictate the diary to be used. The instrumented paper diary creates an objective electronic record of when the diary was being opened/closed or written upon, allowing researchers to confirm whether the date and time written on diary entries correspond to reported diary use. The handwritten entries in the diary can be checked against the electronic record of when the diary was in use to confirm that the person completed the diary entry when they recorded that they completed it. A variety of different types of instrumentation can be used to collect a variety of data regarding the diary use; including whether it is opened, closed, left open for a long period of time, or being carried with people throughout the day.

7. The instrumented paper diary of claim 3, wherein the sensor detects when the diary is closed.

8. The instrumented paper diary of claim 3, wherein the electronic record captures and stores a time corresponding to when the sensor detects that the subject uses the paper diary.

9. The instrumented paper diary of claim 3, wherein the sensor is located underneath a writing surface of the paper form to detect when a user writes in the diary.

10. The instrumented paper diary of claim 3, wherein the sensor detects movement of the diary.

11. The instrumented paper diary of claim 3, further comprising a tamper sensor for detecting when a subject tampers with the electronic instrumentation.

12. The instrumented paper diary of claim 1, further comprising a pen connected to the diary to allow a user to record data and a time on the paper form.

13. The instrumented paper diary of claim 12, wherein the pen includes a sensor to detect when the user writes in the diary.

14. The instrumented paper diary of claim 1, wherein the electronic instrumentation includes a database to store the electronic record as a computer file.

15. The instrumented paper diary of claim 1, wherein the electronic record captures and stores an event indicative of use of the diary, together with a time at which the event occurs.

16. The instrumented paper diary of claim 15, wherein the electronic record further stores the date at which the event occurs.

17. The instrumented paper diary of claim 15, wherein said event comprises opening the diary.

18. The instrumented paper diary of claim 15, wherein said event comprises closing the diary.

19. The instrumented paper diary of claim 1, wherein the electronic instrumentation is visible to a user of the paper diary.

20. The instrumented paper diary of claim 19, further comprising a graphical display for displaying the electronic record to the user of the diary.

21. The instrumented paper diary of claim 1, wherein the electronic instrumentation is covertly connected to the paper form, such that the electronic instrumentation is hidden from a user of the diary.

22. A subject compliance monitoring system, comprising:

an instrumented paper diary including paper forms allowing a subject to enter data and electronic instrumentation for generating an electronic record of diary use; and

an electronic device for displaying and viewing the electronic record.

23. The subject compliance monitoring system of claim 22, further comprising a reader for transferring the electronic record from the instrumented paper diary to the electronic device.

24. The subject compliance monitoring system of claim 23, wherein the reader includes a cable connectable to an interface port on the electronic device.

25. The subject compliance monitoring system of claim 22, wherein the electronic device comprises a personal computer.

27. The device of claim 26, further comprising a paper diary in communication with the electronic device for manually recording clinical trial data.

28. The device of claim 27, wherein the electronic device comprises a sensor for detecting when a user records said clinical trial data.

29. The device of claim 28, wherein the electronic record logs a time when the user records said clinical trial data.

30. The device of claim 28, wherein the electronic record logs a date when the user records said clinical trial data.

31. The device of claim 28, wherein the electronic record logs the duration of a time period during which the user records said clinical trial data.

32. The device of claim 28, wherein the electronic record is compared to the clinical trial data in the paper diary to verify the clinical trial data in the paper diary.

26. A device for monitoring subject compliance in a clinical trial, comprising:

an electronic device for use with a paper diary, wherein the electronic device generates an electronic record tracking clinical trial data.

33. A method of monitoring subject compliance, comprising:

detecting an event related to data entry in a paper diary for recording data; and

capturing and storing a characteristic of the event to generate an electronic record of said data entry.

34. The method of claim 33, wherein said step of detecting an event comprises detecting when the paper diary is opened.

35. The method of claim 33, wherein said step of detecting an event comprises detecting when the paper diary is closed.

36. The method of claim 33, wherein said step of detecting an event comprises detecting when a subject opens the paper diary.

37. The method of claim 33, wherein the step of detecting an event comprises detecting when a subject closes the paper diary.

38. The method of claim 33, wherein said characteristic comprises a time of the event.

39. The method of claim 33, wherein said characteristic comprises a date of the event.
