The Research Electronic Data Capture (REDCap) system and REDCap Survey are powerful software programs created by Vanderbilt University and supported by the REDCap Consortium to facilitate Institutional Review Board (IRB)-approved clinical research and basic research. Data collected in the course of the research are managed by the program, and can be analyzed by commonly used statistical packages, including SAS, Stata, SPSS, and R.
REDCap is a browser-based, metadata-driven electronic data capture software created by Vanderbilt University. The REDCap Consortium is composed of nearly 900 active institutional partners from more than 70 countries. Programming, networking or database experience is not needed to use REDCap. It is designed to use simple interfaces that handle these details automatically. REDCap is secure and web-based: you can input data or build an online survey or database from anywhere in the world over a secure web connection with authentication and data logging. REDCap allows multi-site access for research that uses multiples sites and institutions. OUHSC maintains three instances of REDCap: the Biomedical and Behavior Methodology Core Customization Instance , the Enterprise Instance, and the Development Instance.
The REDCap system provides functionality and features to enable researchers to rapidly develop databases and online surveys. These databases, data entry forms, and surveys are intuitive, easy to use tools for collecting data, including data validation.
The design, use, and maintenance of REDCap are managed by the Biomedical and Behavioral Methodology Core (BBMC). The BBMC supports and enhances study design, data capture, and analytics for Pediatrics research.
REDCap has a flexible and fine-grained authorization matrix, allowing different members of the study team to have different levels of access (none, read-only or edit) to data entry forms, and access to database management and data export tools. There are provisions to restrict access to data export to allow export of de-identified data only. Advanced features of the system include branching logic for dynamic data entry form generation, file uploading, data importing, and embedded calculated database fields.
REDCap enforces authorization granted to each user by providing and/or enabling certain functions, tabs, links and buttons according to granted privileges.
REDCap includes a full audit trail, recording all operations on the data, including viewing and exporting. The audit log records operation, date and time, and the user performing the operation, permitting review of the audit trail as necessary.
REDCap enforces data integrity protection by design; all “databases” created by users are logical data sets on top of a relational database with built-in integrity protection controls. Additionally, REDCap can help to ensure data quality through use of Double Data Entry mode, forms and records locking and electronic signatures.
REDCap software is licensed through the REDCap Consortium at Vanderbilt University. The University of Oklahoma Health Sciences Center joined the REDCap Consortium in 2012.
REDCap has been approved for storage of sensitive data. The Project Owner is responsible for the following:
Any authenticated user has a right to access REDCap, review public databases (e.g., demo databases) and create a new database or modify a database to which a corresponding authorization is granted (e.g., his/her own). Currently, the University of Oklahoma Health Sciences Center Directory serves as the authentication source. There are three REDCap installations available.
The College of Medicine provides funding for two instances of REDCap. The first is a Development Box, which is used for testing REDCap projects and REDCap training. The second REDCap instance the College of Medicine supports is the Enterprise Box, which is used for general development and production. The BBMC funds a third instance of REDCap (casually called the BBMC Box) used primarily by research in the Pediatrics Dept, and by researchers requiring additional customization to their REDCap project.
For those that are new to REDCap, there are many resources available to introduce you to REDCap and get you started. Among these training resources:
