User Permissions “Rights”
User Roles Define custom roles for different user types (Data entry, PI, Monitor…)
Supporting Multi-Site Data Access Group Partitions Double Data Entry Standard and modified usage SSL enabled Secure Server for Internal and External Campus access Configurable Individual “User Rights” Multiple access levels System Access –granted by the REDCap Administrators Project Access –granted by Project Administrator User Rights –set by Project Administrator
Data Access Groups Partition data records among groups of users Each group can only see the data associated with the group they belong to. Each user can only belong to one group “Global” users can be created for cross site management. (i.e. Any user not restricted to a Group)

BEST Practices Consider carefully the amount of data to collect per visit, per event, and overall in every clinical trial Avoid crowding questions Consider the use of closed versus open systems (i.e., forced-choiced questions) Use consistent units of measurement Avoid requiring the respondent to make calculations whenever possible Avoid mixing timeframes in a single section Consider the consequences of creating incomplete or inadequate data collection forms Collect relevant information to address trial objectives at the time of the trial Differentiate between Unknown, Uncertain, and Missing data instead of using the phrase "Not Available“ Spilker and Schoenfelder also give a list of the following helpful pointers which they believe, "refer to issues to consider to assess whether the point is relevant to a particular clinical trial."
Getting Started Submit Request forms Create Project Create Forms User and/or Project access request forms Create Project Select Usage, Type, Data Model, and Scheduling option Create Forms Online designer to graphically create forms Spreadsheet template for advance and large form changes Forms per event designations User Rights Data access, Import/Export Rights, Data Access Groups Form level access Tests forms (Thorough testing will help avoid deployment delays) Move to Production “Status” Start Collecting Data.

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 Changes to forms must be approved by Administrators before they are committed to the project. Changes to the Forms/ Event Grid must be preformed by the Administrators.

Creating Data Access Groups Add Group to Study Add User to Group Only one Group per user
Data Access Group Data Entry Users only have access to their groups data. !!!Users Not assigned to a group have access to all records according to their “User Rights”!!! Multiple accounts available for Study Managers
Double Data Entry Module Standard method Supports only two data entry participants per REDCap Project Option for those creating individual project for each site Modified usage Create duplicate record with “comparison” or prefix/postfix Use comparison tool to compare records. Any user with data entry rights can do DDE

Calculations Simple [weight]*10000/([height]*[height]) Complex Calculating the Mean of groups with null valid range includes zero The following equation will calculate the Mean of a list of variables ( (if(Math.abs([A])>0,[A],0)) +(if(Math.abs([B])>0,[B],0)) +(if(Math.abs([C])>0,[C],0)) ) / ( (if(Math.abs([A])>0,1,if([A]=0,1,0)) +if(Math.abs([B])>0,1,if([B]=0,1,0)) +if(Math.abs([C])>0,1,if([C]=0,1,0)) )
