SUDECOD Standardized Substance Name Char Synonym Qualifier Standardized or dictionary-derived text description of SUTRT or SUMODIFY if the sponsor chooses to code the substance use. The sponsor is expected to provide the dictionary name and version used to map the terms utilizing the external codelist element in the Define-XML document. Perm
SUCAT Category for Substance Use Char Grouping Qualifier Used to define a category of related records. Examples: "TOBACCO", "ALCOHOL", or "CAFFEINE". Perm
SUSCAT Subcategory for Substance Use Char Grouping Qualifier A further categorization of substance use. Examples: "CIGARS", "CIGARETTES", "BEER", "WINE". Perm
SUPRESP SU Pre-Specified Char Variable Qualifier Used to indicate whether ("Y"/null) information about the use of a specific substance was solicited on the CRF. Perm
SUOCCUR SU Occurrence Char Record Qualifier When the use of specific substances is solicited, SUOCCUR is used to indicate whether or not ("Y"/"N") a particular pre-specified substance was used. Values are null for substances not specifically solicited. Perm
SUSTAT Completion Status Char Record Qualifier When the use of pre-specified substances is solicited, the completion status indicates that there was no response to the question about the pre-specified substance. When there is no pre-specified list on the CRF, then the completion status indicates that substance use was not assessed for the subject. Perm
SUREASND Reason Substance Use Not Collected Char Record Qualifier Describes the reason substance use was not collected. Used in conjunction with SUSTAT when value of SUSTAT is "NOT DONE". Perm
SUCLAS Substance Use Class Char Variable Qualifier Substance use class. May be obtained from coding. When coding to a single class, populate with class value. If using a dictionary and coding to multiple classes, then follow Section 4.2.8.3, Multiple Values for a Non-Result Qualifier Variable, or omit SUCLAS. Perm
SUCLASCD Substance Use Class Code Char Variable Qualifier Code corresponding to SUCLAS. May be obtained from coding. Perm
SUDOSE Substance Use Consumption Num Record Qualifier Amount of SUTRT consumed. Not populated if SUDOSTXT is populated. Perm
SUDOSTXT Substance Use Consumption Text Char Record Qualifier Substance use consumption amounts or a range of consumption information collected in text form. Not populated if SUDOSE is populated. Perm
SUDOSU Consumption Units Char Variable Qualifier Units for SUDOSE, SUDOSTOT, or SUDOSTXT. Examples: "OUNCES", "CIGARETTE EQUIVALENTS", "GRAMS". Perm
SUDOSFRM Dose Form Char Variable Qualifier Dose form for SUTRT. Examples: "INJECTABLE", "LIQUID", or "POWDER". Perm
SUDOSFRQ Use Frequency Per Interval Char Variable Qualifier Usually expressed as the number of repeated administrations of SUDOSE within a specific time period. Example: "Q24H" (every day). Perm
SUDOSTOT Total Daily Consumption Num Record Qualifier Total daily use of SUTRT using the units in SUDOSU. Used when dosing is collected as Total Daily Dose. If sponsor needs to aggregate the data over a period other than daily, then the aggregated total could be recorded in a Supplemental Qualifier variable. Perm
SUROUTE Route of Administration Char Variable Qualifier Route of administration for SUTRT. Examples: "ORAL", "INTRAVENOUS". Perm
TAETORD Planned Order of Element within Arm Num Timing Number that gives the planned order of the Element within the Arm for the Element in which the substance use started. Null for substances that started before study participation. Perm
EPOCH Epoch Char Timing Epoch associated with the start date/time of the substance use. Null for substances that started before study participation. Perm
SUSTDTC Start Date/Time of Substance Use Char Timing Start date/time of the substance use represented in ISO 8601 character format. Perm
SUENDTC End Date/Time of Substance Use Char Timing End date/time of the substance use represented in ISO 8601 character format. Perm
SUSTDY Study Day of Start of Substance Use Num Timing Study day of start of substance use relative to the sponsor-defined RFSTDTC. Perm
SUENDY Study Day of End of Substance Use Num Timing Study day of end of substance use relative to the sponsor-defined RFSTDTC. Perm
SUDUR Duration of Substance Use Char Timing Collected duration of substance use in ISO 8601 format. Used only if collected on the CRF and not derived from start and end date/times. Perm
SUSTRF Start Relative to Reference Period Char Timing Describes the start of the substance use relative to the sponsor-defined reference period. The sponsor-defined reference period is a continuous period of time defined by a discrete starting point and a discrete ending point (represented by RFSTDTC and RFENDTC in Demographics). If information such as "PRIOR" was collected, this information may be translated into SUSTRF. Not all values of the codelist are allowable for this variable. See Section 4.4.7, Use of Relative Timing Variables. Perm
SUENRF End Relative to Reference Period Char Timing Describes the end of the substance use with relative to the sponsor-defined reference period. The sponsor-defined reference period is a continuous period of time defined by a discrete starting point and a discrete ending point (represented by RFSTDTC and RFENDTC in Demographics). If information such as "PRIOR", "ONGOING", or "CONTINUING" was collected, this information may be translated into SUENRF. Not all values of the codelist are allowable for this variable. See Section 4.4.7, Use of Relative Timing Variables. Perm
SUSTRTPT Start Relative to Reference Time Point Char Timing Identifies the start of the substance as being before or after the reference time point defined by variable SUSTTPT. Not all values of the codelist are allowable for this variable. See Section 4.4.7 , Use of Relative Timing Variables. Perm
SUSTTPT Start Reference Time Point Char Timing Description or date/time in ISO 8601 character format of the reference point referred to by SUSTRTPT. Examples: "2003-12-15" or "VISIT 1". Perm
SUENRTPT End Relative to Reference Time Point Char Timing Identifies the end of the substance as being before or after the reference time point defined by variable SUENTPT. Not all values of the codelist are allowable for this variable. See Section 4.4.7 , Use of Relative Timing Variables. Perm
SUENTPT End Reference Time Point Char Timing Description or date/time in ISO 8601 character format of the reference point referred to by SUENRTPT. Examples: "2003-12-25" or "VISIT 2". Perm
