Good Practices in Data Management(e.g. Redcap)
Presented by Diantha Howard,CCTS Biomedical Informatics
December 2012
Goals of Data Management
• Consistent• Accurate• Securely stored (including, but not limited to
HIPAA issues)• Attributable (i.e. “who entered”)• Accessible for analysis
What is REDCap
• Software and methodology for electronic data collection and management
• REDCap database and REDCap Survey• http://project-redcap.org/• https://apollo.pantheon.fletcherallen.org/redcap– (REDCap database)
• https://ccts.uvm.edu/redcap– (REDCap survey only)
REDCap History
• 2004: Started at Vanderbilt GCRC• 2006: Consortium started• 2012: 511 Institutional Partners– World-wide (48 countries in 2012)– From CTSA, RCMI and other institutions– Over 53,400 studies with over 71,000 end-users
Advantages of REDCap
• Secure, web-based, with authentication and data-logging
• Free to REDCap Consortium members (UVM CCTS is a member)
• Fast and flexible to design and implement• Multi-site access (here through FAHC gateway)• Exports data & syntax to common stat packages
(SPSS, SAS, Stata, R/S-Plus)• 21 CFR Part 11 Capable

Databases you have access to:
Training Resources
• Videos and some examples– Overview– Creating data forms– Scheduling Module– Types of Databases– Data access groups– Locking records
• “General Help & FAQs”
Setting up a Project
Example of Data Entry Form
Online Form Designer
Adding a field
Data Comparison Tools
Data Logging (Audit trail)
Data Export and Import
• Data Export Tool:– Select all or certain fields from all or certain forms– De-identification options– Export data to a .csv file or– Export data and syntax for SAS, SPSS, R, Stata
• Data Import Tool:– Download template (.csv) once database created– Enter data into template and upload back to REDCap– For Longitudinal study, each event must be imported
separately
REDCap Calendar
Randomization Module
• Enabled when creating project, or by modifying project settings
• Can be stratified by fields in your data, or within Data Access Groups
• You create allocation scheme, then upload to REDCap, which then will assign subjects
More REDCap Applications• File Repository
– Can upload and retrieve documents and files– E.g. Consent forms; exported data & syntax
• Rights administration– You can assign rights to users on your study – Global rights: Import/ export / reporting / database design– Read/ edit/ no access (on form-by-form basis)
• Data Access Groups– For Multi-site trials; users can only see data entered by their access group
• Report Builder– Create and save simple queries/ reports
• “Send-It” (Secure File Transfer)
Report Builder – Creating Report
