REDCAP RESEARCH ELECTRONIC DATA CAPTURE Amy Wahlquist February 2, 2012 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 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 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 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 FIELD TYPES Text box Notes box – no default validation, bad for analysis Calculated field Used for all “free” entry including strings, numerics, dates 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 VALIDATION (TEXT BOX) Date Validation (date) allows for calendar to pop up and makes sure date is entered in usable format If possibility for missing information (e.g., day), consider entering day, month, and year separately instead of date Number/Integer Use pop up calendar to choose date or enter with keyboard Different date format options Add ranges - warns if outside range, but still allows it Others Date/time Date/time with seconds Email Phone Time Zip 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 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*) 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” 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 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 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) 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** 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 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) RESOURCES REDCap Shared Library Forms already created and validate can be imported directly into library Listserv: email [email protected] (in body of message, type the word “subscribe”) Email [email protected] (to reach administrators) REDCap videos ADDITIONAL FEATURES Parent Child Linking Double Data Entry
