We collected data at three time points using two systems. The PRB-RSC survey used the Association of Pediatric Program Directors (APPD) Longitudinal Educational Assessment Research Network (LEARN) ID system. The remaining study data were collected and managed using REDCap electronic data capture tools hosted at the Ohio State University [35 (link),36 (link)]. REDCap (Research Electronic Data Capture) is a secure, web-based software platform designed to support data capture for research studies, providing 1) an intuitive interface for validated data capture; 2) audit trails for tracking data manipulation and export procedures; 3) automated export procedures for seamless data downloads to common statistical packages; and 4) procedures for data integration and interoperability with external sources.
