The REDCap model has been successful to date, growing from a single site to a global consortium over the course of approximately 13 years. The iterative software design philosophy and incremental consortium growth fostered a collaborative spirit during REDCap’s early days, which has been sustained through the active participation of thousands of REDCap administrators in REDCap calls, mailing lists, working groups, and conferences. Software feature requests and guidance from active research teams have enabled the platform to grow from a rudimentary feature set (data capture, data export, logging) to a rich set of modules capable of supporting diverse research operations on almost any scale. More than six thousand journal articles have cited use of the software platform in conducting studies during the period between 2004 and 2018 [60]. While bibliometric capture and analysis methods (Figure 3) provide evidence of value for REDCap in diverse scientific research domains, the platform is used at Vanderbilt and across REDCap Consortium partner institutions for many other use cases (Figure 4), including operational support, quality improvement projects, and even as a sub-component for larger systems
