2. What is REDCap?
Research Electronic Data Capture (REDCap)
REDCap is a web-based application designed to
give Researchers and Clinicians the capacity to
create and manage databases and surveys in order
to support data capture for research studies.

4. REDCap Features
• Fast and flexible data entry and form creation in the web interface
• Autonomous multi-level user access
• Batch data load using automated data import procedures
• Seamless data export to common data analysis packages
• Easy and secure multi-site access
• Fully functional and customized design for longitudinal research
studies
• Aggregate graphical data view and descriptive statistics
• Ad hoc reporting and analysis
• Complete audit trails for tracking data manipulation and user activity
5. Fast and Flexible Data Entry and Form Creation
in the Web Interface
✓ REDCap provides various data field types, such as text box, notes
box, calculated field, multiple choice, checkboxes, descriptive text,
section header, dynamic query, etc
✓ Questions using branching logic are supported
✓ Research team can easily mark identified data in the interface and
create access limits on those fields
✓ Built-in data validation to maintain
data quality
8. Autonomous Multi-Level User Access
Researchers choose what people and group have access to:
✓ Data, both identified and de-identified
✓ Data export & import capability
✓ User rights management
✓ View reports
✓ View logging
10. Seamless Data Export to
Common Data Analysis Packages
Researchers can export data to a variety of
statistical analysis packages
(SPSS, SAS, R, Excel, etc)
✓ Researches can grant or restrict access to export data
for analysis
✓ Data exports are customizable including all or some of
the data forms and fields
✓ Exports can include identified
or only de-identified data
depending on user and group
rights

11. Easy and Secure Multi-Site Access
✓ Research teams can input data
simultaneously, from across the hall
or across the country.
✓ Data Access Groups can be
implemented to segregate users and
the data. By placing users into data
access groups, they will only be able
to access records created by someone
in their group.
14. Ad Hoc Reporting and Analysis
Reports can be generated:
✓ On the fly
✓ Saved and used over and over within the interface
15. Complete Audit Trails
For Tracking Data Manipulation
and User Activity
Data logging provides information about:
✓ who has changed the instrument
✓ who has changed the data
✓ who has accessed data
✓ when these events occurred
