Overview What is it… Where is it… What are the costs… REDCap Features (A brief tour of the system) … Getting Started (Creating a REDCap project) … Demonstration…
Need for Data Capture Software Convenient uniform data entry method – Stateless web-based – Secure WUSM HIPAA compliant centralized data store. Easy to use multi-purpose clinical database – Not Excel, Not Access, Not 3-4 composition notebooks somewhere on the top shelf Reduce data cleaning effort during analysis.
REDCap System (What is it?) Easy to use, web based Research data capture system Metadata (Form) driven data store development Generic clinical data system with adaptable features covering Surveys, Cross-sectional, and longitudinal study models Provides data validation at time of entry, and user based data access restrictions. Provides easy mechanism to view and export data in a variety of formats for common analysis tools. Designed to be a self service tool

Move to Production Status Production Status on the Production Server Data dictionary changes are stored by the system Global deletion of data from system prohibited High Risk changes to forms must be approved by Administrators before they are committed to the project. Changes to the Forms/ Event Grid Events may be added but not removed
Current Usage Costs Offered as an Investigator Resource for Washington University Institute of Clinical and Translational Sciences(ICTS) and Siteman Cancer Center (SCC) members. No charge for data or file storage. – File size currently limited to 32MB per file No limit on the number of projects per study. Basic technical support and usage guidance provided by REDCap adminstators.
Treatment Randomization Module Stratified Randomization – Use up to 14 project fields – Multiple Choice fields Group Stratifications – Data Access groups – Designated Multiple Choice Grouping Field Randomization Template – Generated based on selected criteria – Development and Production Tables – Once in Production status treatment Allocation tables are locked
Enable Randomization Feature in Project Settings
Set up Randomization on Project Setup Screen
Randomization User Rights Randomization Rights – Setup up allocation tables Create and load Trt allocation tables – View current randomization Status Check progress of randomization – Randomize Participant
Treatment Randomization Module
Select and Save Criteria
Download Allocation Table Template Example allocations !! You will need to assign your treatment allocations based on your projects statistical analysis plan
Upload Allocation Tables Duplicate allocations !! You may not use the exact same allocation table for Production status that you used in Development status
Getting Started Enable Randomization – Select Data Entry Forms project – Set User Rights for users who will administer and setup the randomizations Select Fields – Up to 14 strata fields – Set grouping if applicable – Set Treatment Field Allocation Templates – Save randomization model – Download Allocation templates and replace content according to study protocol – Upload Development/Production allocation tables – Tables become locked once project is put into Production Status Randomization fields clear Monitor Randomization – Dashboard
