  1. REDCapResearch Electronic Data Capture Amy Wahlquist February 2, 2012

  2. Getting Started • https://redcap.musc.edu • Login with NetID and password • Welcome screen • Home • My Projects – list of all projects you currently have access to • Create New Project • Training Resources – videos • Help and FAQ • Send-It – Secure data transfer application

  3. Creating a new database • Project title • Purpose • If you choose research, then you need PI name, IRB number, type of research • None is required, but helpful to have all information • If you choose other, then give description • Type of project • Survey – allows you or participants to enter data (one time/person) • Data entry forms (classic or longitudinal) • Survey and data entry forms

  4. Database Information • Project Home • Check data quality (once data is collected) • Current users • Project statistics • Project Setup • Current status • Settings – change type/purpose and customizations • **Design/data dictionary** • Links/user rights/share instruments • Change status/draft mode • Other Functionality • Revision History • Copy/delete/erase data/archive database • Menu (on left) • Data entry forms • Applications • Help

  5. Creating Forms • Demographics form created automatically • Can modify or delete • **1st variable on 1st form is the unique identifier for database** • Add forms/variables as needed • Variable names must be unique – not case sensitive • Variable labels can be reused (not always recommended) • Form must have at least one variable to be saved

  6. Field Types • Text box • Used for all “free” entry including strings, numerics, dates • Notes box – no default validation, bad for analysis • Calculated field • Must provide equation for calculation • Use previously defined variables or constants • Multiple choice – only one answer • Radio buttons • Drop down list • Checkboxes (more than one answer) – REDCap creates dummy variables for you • Yes/No • True/False • Slider/Visual Analog Scale • File upload • Descriptive text • Section header (must have at least one variable after header before section can be added) *not an option for the first variable on a form

  7. Validation (text box) • Date • Validation (date) allows for calendar to pop up and makes sure date is entered in usable format • Use pop up calendar to choose date or enter with keyboard • Different date format options • If possibility for missing information (e.g., day), consider entering day, month, and year separately instead of date • Number/Integer • Add ranges - warns if outside range, but still allows it • Others • Date/time • Date/time with seconds • Email • Phone • Time • Zip

  8. Field Options • “Identifier” – tags variables with protected health information for exporting de-identified data (dates are automatically tagged) • “Required” – prompts data entry person not to leave something missing, but does not actually “require” it

  9. Branching Logic • For fields that should only be asked at certain times • Convenience to data entry person • No difference in branching missing vs. left intentionally blank • Advanced vs. Drag-N-Drop • Branching can use variables from separate forms (*NEW feature*)

  10. Tips When Creating Forms • Drag and drop to reorder • Copy/edit to make quick copies of similar variables • Note that when “copy” is used, the variable name is generated and may need be changed • Use Data Export Tool to export data dictionary to Excel file to make changes and then upload new data dictionary • Multiple choice options creates numeric values for options “behind the scenes” • Always starts at 1 and increases • Can force values you want • Be consistent!! • Print CRFs after creating database to have a “hard copy”

  11. Beware • Cannot specify significant figures to enter • Cannot force entering data in certain units (kgs, lbs) • Add a field note to remind the data entry person • Calculations will remain missing if any of the variables used to create it are missing • Creating adverse event forms

  12. Longitudinal Studies • Define events • If you use the same # days offset (1,1,1, etc), events will be alphabetized • Create arms if necessary (different schedule of events) • Designate forms for events

  13. Scheduling • Must have checked “Enable Scheduling Module” under “Project Settings” (Control Panel to change) • Scheduling • Generate schedule for each patient based on events • Modify/add visits as needed • Can print for records • Calendar tool • Add other events – per patient or in general • Agenda (upcoming for all patients)

  14. Data Export/Import • Export • “Simple” takes all variables • “Advanced” • Choose forms/variables to export • De-identification options • Citation notice • Software – need to download all files provided • Excel, SPSS, SAS , R, STATA • Data import • Data must be in same format as REDCap database • Won’t create variables – only import data into existing variables • **This is different from the data dictionary upload which will create variables**

  15. Other Tools • Data comparison tool • Logging • File repository • User rights – be careful with default options (especially exporting rights) • Data access groups – limits access to database records • Graphical view and stats – quick and dirty view • Data quality • Report builder

  16. Production Status • Request through “Project Setup” • https://sctr.musc.edu/ • Request Service through SPARK • After in “production” - changes are not “live” until submitted for approval (use draft mode)

  17. Resources • REDCap Shared Library • Forms already created and validate can be imported directly into library • Listserv: • email redcap-users-request@musc.edu (in body of message, type the word “subscribe”) • Email redcap@musc.edu (to reach administrators) • REDCap videos

  18. Additional Features • Parent Child Linking • Double Data Entry
