Interest in REDCap spiked once approximately 50 partners had joined the Consortium and membership trended upwards in 2009. We published a descriptive paper about the REDCap platform to support research teams needing to cite data management capacity in grants and methods sections for research publications[26]. We solidified our membership processes during the early stages of Phase 5, enabling our existing REDCap support team to manage the growth. A rapidly growing user base drove functionality requests and use cases to unprecedented rates. The REDCap development team at Vanderbilt designed new software modules to facilitate clinical trials (e.g., participant randomization, data query workflow) and support direct data capture from patients via user-facing surveys. We continued support via consortium listserv communication and added a weekly programmer-led “Technical Assistance Call” to assist with complex technical help requests.
