REDCap Data Management
How to begin using REDCap to collect and manage your research data
CTSC Biomedical Informatics Program
What is REDCap?
REDCap (Research Electronic Data Capture) is a secure web application for building and managing online databases for research
REDCap is HIPAA-compliant, we will worry about data security and data compliance, you can focus on the research
Worked with Research IT, IT Security, Compliance, Legal, and the IRB to launch REDCap
For more information: http://www.ucdmc.ucdavis.edu/ctsc/redcap/
REDCap Text for IRB and Grant Submissions
Six Step Process to Using REDCap
1. Kick-off Meeting
2. Develop Data Dictionary
3. Review Data Dictionary
4. Create Database and Request User Access
5. Final Database Review
6. Begin Entering Data!
Kick-off Meeting
Meet with CTSC Biomedical Informatics staff – Discuss project workflow
– Discuss milestones and deadlines
Researcher must complete a CTSC Application for Resource Use
Researcher must sign the REDCap Project Level Agreement
Six Step Process to Using REDCap
1. Kick-off Meeting
2. Develop Data Dictionary
3. Review Data Dictionary
4. Create Database and Request User Access
5. Final Database Review
6. Begin Entering Data!
Developing the Data Dictionary
Variable / Field Name Form Name Section Header Field Type Field Label Choices Field Note Text Validation Type Text Validation Min Text Validation Max Identifier? Branching Logic Required Field?
Each data point
Variable / Field Name – Lowercase, no special characters, underscores
allowed
Form Name Section Header Field Label Choices
– All choices are coded (1, Choice 1 | 2, Choice 2, etc.)
– Although “Choice 1” is selected, the value “1” is stored, useful during analysis
Field Note
Sample Form
Section Header
Field Label
Field Note
Choices
Field Type
text – text box used to capture numerical values and text data
notes – large text box used to capture text data, usually for comments or notes
dropdown – drop down list used to select a single item from a predefined list of items
radio – radio buttons to select a single item from a predefined list of items
checkbox – checkboxes to select multiple items from a predefined list of items
yesno – radio button for simple Yes/No response
Validation
For text fields – – number, min/max
– integer (whole numbers, no decimal places), min/max
– date (date_ymd, date_mdy, date_dmy), min/max
– time (datetime_ymd, datetime_mdy, datetime_dmy), min/max
– phone
– zipcode (5 digits)
Branching Logic
Allows fields to be displayed when certain data is entered/selected
If “Female” is selected as Gender, a question for “Past pregnancy” will be displayed
[gender] = “0” would be entered into the branching logic column for the “Past Pregnancy” data point

6. Begin Entering Data!
Review Data Dictionary
Research team will meet with informatics staff and a biostatistician to go over the data dictionary
– Informatics staff can communicate with the biostatistician regarding the data model
– Biostatistician can provide guidance to the research team on how certain data points should be captured to facilitate analysis

3. Review Data Dictionary
4. Create Database and Request User Access
5. Final Database Review
6. Begin Entering Data!
Requesting Access (this will only have to be done once)
Submit a Lotus Notes Online Access Request
Send a signed REDCap End User Agreement to the informatics staff working with you (fax, inter-office mail, or scan and email)
Informatics staff will be using your data dictionary to create the database
