Determine Forms

    For non-standardized Standardized forms (e.g., SF-36) have a predefined data definition.  For all other variables, the main factors that determine what variables to put on a form are:

• Time and Collection Methods (see image)
  • What variables are collected together at specific time points?
    • Note: Forms can be shared across studies (e.g., Demographics, Contact Information)
  • Are all the variables on a forms ALWAYS collected together?  If not, often best to separate time-related groups of variables (e.g., rare vs. common lab values)
  • Image Added
• Domain - What variables belong to a given content domain (e.g., surgical vs. imaging variables)?
• Practical -
  • Create Once - Forms are created ONCE and then used at one or more study visits. 
  • Image Added
  • Pre-Defined Fields - Exclude any fields that are pre-defined in Studytrax:
    • Reference ID
      • Global ID (e.g., SSN, MRN, bogus auto-generated)
    • Project ID
      • Study specific (i.e., screening ID)
    • Randomization ID
    • Name (i.e., First, Last, Middle Initial)
    • Site
