Survey
Can be targeted for specific participant
Can be anonymous. A participant does not need to be a registered user of REDCap to receive or respond to a survey
Data Capture
Intended for a PI, research team member or collaborator

4. Who can use REDCap?

Data backups, software upgrades, and system maintenance are handled automatically by Emory Library and Information Technology Services (LITS)
Data is secured via SSL
Allows multi-site access
Research teams can input data simultaneously, from across the hall or around the world

6. Additional reasons why to choose REDCap over Excel and Access
REDCap General Overview
Additional reasons why to choose REDCap over Excel and Access
HIPAA Compliant
Researchers can build databases rapidly
Research teams have autonomy
Create a new database or survey
Project design and setup
Project Administrators can assign user permissions and roles to others and grant rights for data import and export.
User can have access to identified or de-identified data, and the ability to create and delete records.

REDCap General Overview
Instrument creation and data entry are easy

8. REDCap Data Collection
Classic Data Collection
Form used for a single time period (questions asked once)
Longitudinal Data Collection
Form used for multiple time periods (e.g. vitals at initial visit, 30 days, 60 days, etc.)
Same form used for all time periods
Calendar used to schedule subject visits

9. REDCap Features Branching logic is supported
Calculated fields are supported
Project administrators can copy projects
Researchers can make modifications to their project any time during the study
Draft mode (design phase)
Production mode (data collection phase)

10. REDCap Confidential Data
Identified data:
What are identifiers?
Examples: Name, Social Security Number, etc.
Identified data can be selected in REDCap to create access restrictions on those fields

12. REDCap User Rights User rights Data Access Groups
Create user roles (e.g. data entry personnel) for your project when you have several users who will require the same User Rights. Add new users with custom rights (just as before) or assign users to roles.
Data Access Groups
Data Access Groups (DAGS) restrict viewing of data within a project. A typical use of Data Access Groups is a multi-site study where users at each site should only be able to view data from their site but not any other sites. Users at each site are assigned to a group, and will only be able to see records created by users within their group.
