CREATING A NEW DATABASE


Project title
Purpose

If you choose research, then you need PI name, IRB number, type of research



If you choose other, then give description
Start project from scratch or begin with template?


None is required, but helpful to have all information
If beginning with a template, cannot “go back” and will have to make all changes
manually – by enabling options you want to add
Templates available

Human Cancer Tissue Biobank
Longitudinal Database (1 or 2 arms)
Multiple Surveys (classic or longitudinal)
Project Tracking Database
Randomized Clinical Trial

CREATING FORMS

From template – some forms created automatically

Can modify/rename/delete/reorder
**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)

FIELD TYPES

Text box



Notes box – no validation available, 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 – this can be from other forms
Multiple choice – only one answer
Drop down list
 Radio buttons







Checkboxes (more than one answer) – REDCap creates dummy variables for you
Yes/No
True/False
Slider/Visual Analog Scale
File upload
Descriptive text – with optional image/file attachment
Begin new section (must have at least one variable after header before section
can be added) *not an option for the last 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
Decimal place option – doesn’t tell you on the form until you enter it wrong –
can use field note option
Others







Date/time or Date/time with seconds
Email
Phone
Time
Zip
Letters only
MRN/SSN
FIELD OPTIONS
“Required” – prompts data entry person not to leave
something missing, but does not actually “require” it
 “Identifier” – tags variables with protected health
information for exporting de-identified data


“Check for Identifiers” – design your data collection
instruments – can do them all at once
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
Download data dictionary to Excel file to make changes
and then upload new data dictionary - for large number
of similar changes
 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 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 - still not a great way to do
this

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 instruments for events
SCHEDULING
Must have enabled “Scheduling Module” under optional
modules and customizations on “Project Setup”
 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 (that you have permission to download)
 “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 (.csv file)
 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
 Check permissions when you add a new form

Graphical view and stats – quick and dirty view
 Data quality
 Report builder

PRODUCTION STATUS
Request through “Project Setup”
 Request Service through SPARK



https://sctr.musc.edu/
After in “production” - changes are not “live” until
submitted for approval (use draft mode)
RESOURCES

REDCap Shared Library


Forms already created and validated 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 (cannot be used with longitudinal)
 Double Data Entry
 Randomization Module (needs certain user rights)
 Surveys – can now do multiple surveys in the same
database
 Data Quality
 Report Builder
