REDCap (Research Electronic Data Capture) Project History
2004 Needs Assessment
Researchers needed help managing data for small/medium sized non-trial research projects (pilot, R01, PPG)
Hypothesis Researchers will do the right thing (secure, audit trails, etc) if provided an easy way to get needed tools Problem
Many projects, few resources

REDCap Project History
Solution:
Metadata-driven application (no per-project programming)
2004 - First REDCap project operational at Vanderbilt 2006 - REDCap Consortium Launched REDCap Consortium to share with other universities and foster collaboration for future development
