I don’t believe any information is transferable from 1 trial to another and patient data protection laws make using it without consent impossible. Technology can be used however to expedite patient selection using digital filtering based on responses similar to job recruiting sites and resumes. Certain psychological tests can be done to reduce for patient infidelity when using the device.(not following direction when not in the hospital etc). Digital surveys outside of the ones done in person can be conducted to learn more about the patient experience with the device outside of the functionality and compatibility of the device in or on the person.
I do agree that the monitoring phase is the most likely phase for technology to help since you can access logs irt as opposed to when a notebook is handed in or ensure that all questions that they need to answer in each log are answered as well as have automated reminders. The biggest challenge in actually incorporating technology in monitoring is the safety of information and the use of that information.
