Values provide context for values in the TIG Core column to determine when a field should be present on the CRF. Values in this column are:

  • A short description of the data collection context
  • N/A for when only 1 context is provided for the domain

This column can be used to filter the metadata table for specific data collection scenarios when developing CRFs.

9Question TextCRF and System Design

Provides full sentence/question forms to prompt for data. Values in this column are: 

  • Without text in brackets or parentheses, to be used as-is
  • With text in brackets, indicating an option on the verb tense of the question or text that can be replaced with protocol-specified verbiage or controlled terminology
  • With text in parentheses, indicating options for text (e.g., singular/plural) or optional text that may be omitted
  • With text separated with a forward slash, indicating options for wording from which an implementer may choose.

When the value in the Observation Class column is Findings, controlled terms must be used to create question text for the data collection field on the CRF.

  • With text in brackets, to be replaced with protocol-specified verbiage or controlled terminology
  • With text in parentheses, indicating optional text
  • With text with NULL indicating the prompt is not required on a CRF screen/page if not needed

When the value in the Observation Class column is Findings, controlled terms must be used to create prompt text for the data collection field on the CRF. 

The CDASH Model can be referenced to create conformant alternative prompt text.

11Data Type Tabulation Dataset Generation

Specifies the data type of the variable. Values for in this column are:

  • Num for numeric data
  • Char for character or alphanumeric date

12

Collection Core 

CRF and System Design

Specifies expectations for inclusion of the collection field on the CRF. Values are used with values in the Data Collection Scenario column to determine when a field will be present on the CRF. Values in this column are:

  • HR, for fields that are Highly Recommended and should always be included on the CRF
  • R/C, for fields that are Recommended/Conditional and should be included on the CRF per certain conditions
  • O, for fields that are Optional and should be included on the CRF when needed to support data collection

When the value in this column is R/C, conditions are described in the Implementation Notes column.

13Case Report Form Completion InstructionsCRF Completion Instructions

Provides recommended example instructions for the data collection field to support authoring of study-level instructions for how to enter collected information on the CRF

14Tabulation Target Tabulation Dataset Generation

This column provides the suggested mapping to the tabulation dataset variable. Values in this column are:

  • The name of the tabulation dataset variable to which the value of the data collection variable will be mapped
  • N/A for when no direct mapping to a tabulation dataset variable is available
  • Text with the prefix SUPPSUPP–.QNAM

  • Codelist names in parentheses separated by commas, when more than 1 codelist is associated
  • N/A for when controlled terminology is not associated with the data collection field and variable
17Subset Controlled Terminology/CDASH Codelist Name

CRF and System Design

Tabulation Dataset Generation

Specifies CDISC CT terms or the name of the CDASH subset codelist associated with the data collection field and variable.Values in this column are:

  • A controlled terminology term or a subset of terms from the codelist referenced in the Controlled Terminology Codelist Name column
  • The name of the CDASH subset codelist in parentheses
  • N/A for when specific controlled terms or CDASH subset terminology are not applicable

Implementation Notes 

CRF and System Design

Tabulation Dataset Generation

Provides further context for implementation of data collection fields and variables. Values in this column may include:

  • Rationale for implementation guidance
  • Additional instructions for implementing fields and variables on the CRF and in the underlying database structure
  • Example values which could appear in the in the data collection field and variable
  • Additional guidance for mapping values from data collection to tabulation variables
