The Vanderbilt team also maintains control of the REDCap software development trajectory, although we frequently seek input on features and prioritization from the Consortium. As an academic medical center and main consumer of REDCap, we must remain responsive to national and international research priorities to support our own research community. The mixed funding model we use to support REDCap also requires that we prioritize development in areas consistent with the larger funding initiatives (e.g., PCORI grant initiatives led to many features and functions necessary for participant engagement and patient reported data). While there is a limit to core software development and support, we have created platform features (e.g., restful API services, sustained plug-in architecture) that enable any REDCap Consortium partner to build and share ‘add-on’ features that might be necessary to support individual study needs.
