REDCap (Research Electronic Data
• Online data entry into a database using a web interface,
eliminating the need for paper forms.
• REDCap project was initiated at Vanderbilt University
• ~89 consortium partners, 1540 studies with over 5510 endusers
• Stanford University, a consortium partner
• The data is committed and stored to a “MySQL” database,
placed in a secure IRT server, protected by adequate layers of
