The tablet wirelessly connects to the web to allow data entry into a
secure, web-based portal of the EDC system. The research staff and the
patient are required to log into the secure website with a username
and password. A separate username and password are generated for
the patient so that only the patient's record is visible. The patient can
only enter data into the currently open time-point to prevent incorrect
data entry. No data is stored on the portable tablets. Based on the
response patterns defined by algorithms for the three intervention
groups, the EDC generates responses in the system to indicate the
patient's intervention status on the tablet (BI, RT, follow-up calls).
This portable tool accommodates home-based primary care and produces
point-of-care triggers for the designed staff to provide the intervention
as indicated. Only designated research staff have access to
the information.
