Operations
• Data Access Groups
– Allow people at multiple sites to contribute to the same database,
without seeing other people’s data.
• Calendar & Scheduling
– Create a list of upcoming events and track the status of those
events.

REDCap as a Platform for more
• Interoperate with other programs via Application
Programmer Interface (API)
– Web Services interface for reading and writing data
– Example: Data Transfer Service – incorporates data from other
database, such as lab results.
• Add new REDCap functionality with Plugins
– PHP code on same server as REDCap
– Can not replace existing functionality

What data can REDCap manage?
• Numbers, text, dates, files, lists (radio/checkbox/multiple),
branching, calculations
• Simple Schemas
– Designed for a single table of information
– 1:many relationship is possible, but tedious to create
– Many:many only possible by using multiple REDCap databases.
• Electronic Protected Health Information (ePHI)
– IU has put in place appropriate administrative, technical, and

security rule
ACCELERATING CLINICAL AND TRANSLATIONAL RESEARCH
www.indianactsi.org
What data is not allowed in REDCap?
• When storing ePHI, you remain responsible for
privacy, security, and compliance. You need IRB
approval and a Data Management Plan. Technical and
physical controls are provided, but you remain
responsible for administrative controls.
• REDCap is for use only in support of academic research.
Do NOT use REDCap for other uses, for instance to store
official university business data, patient care data, or
electronic health records (EHRs).
