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.
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.
Below are some of the frequently asked questions regarding REDCap. If your question is not listed below you can send an e-mail to Thomas Wilson.
Q: How much does it cost to use REDCap?
The use of REDCap is offered on the University of Oklahoma Health Sciences Center (OUHSC) campus free of charge.
Q: Who can use REDCap?
REDCap is available to all persons with a current OUHSC login id.
Q: How do I get started using REDCap?
To get started using REDCap contact the BBMC using this online form and a representative will contact you to discuss your project.
Q: Does REDCap require a lot of experience with programming, networking, and/or database construction?
No. REDCap uses a simple design interface that will handle all of the programming, networking, and database details automatically.
It is recommended that once designed, you have a member of the BBMC review your project. It is important to consider the planned statistical analysis before collecting any data. The BBMC can help assure that you are collecting the appropriate fields, in the appropriate format necessary to perform the needed analysis.
Q: Does REDCap have online survey capability?
Yes. REDCap has two online survey options, a private survey and a public survey. The private survey utilizes a participant's e-mail address and REDCap sends a unique survey url to each individual participant. This option offers participants the ability to Save and Return Later using a validation code that is supplied to them automatically by REDCap. Participants may only take the private survey one time. The public survey option creates a single url that can be e-mailed to participants or posted on a website. This type of survey can be taken multiple times by the same participant.
Q: Is REDCap HIPAA compliant?
Yes. REDCap has been approved for storage of sensitive data.
Q: Can I import data from my current research into REDCap?
Yes. Data can be imported into REDCap using the Data Import Tool. The Data Import Tool requires that data to be imported is in CSV (comma separated variables) format. The order of the fields or the number of fields being imported does not matter, except that the record identifier (e.g. Subject ID) must be the first field.
Q: What data export options are available in REDCap?
REDCap creates export files in the following formats: Excel CSV, SPSS, SAS, R, and STATA

Login to REDCap:
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:
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:
