DOMAINDomain AbbreviationCharSUIdentifierTwo-character abbreviation for the domain.Req
USUBJIDUnique Subject IdentifierChar
IdentifierIdentifier used to uniquely identify a subject across all studies for all applications or submissions involving the product.Req
SUSEQSequence NumberNum
IdentifierSequence number given to ensure uniqueness of subject records within a domain. May be any valid number.Req
SUGRPIDGroup IDChar
IdentifierUsed to tie together a block of related records in a single domain for a subject.Perm
SUSPIDSponsor-Defined IdentifierChar
IdentifierSponsor-defined reference number. May be preprinted on the CRF as an explicit line identifier or defined in the sponsor's operational database. Example: Line number on a Tobacco & Alcohol Use CRF page.Perm
SUTRTReported Name of SubstanceChar
TopicSubstance name. Examples: "CIGARETTES", "COFFEE".Req
SUMODIFYModified Substance NameChar
Synonym QualifierIf SUTRT is modified, then the modified text is placed here.Perm
SUDECODStandardized Substance NameChar*Synonym QualifierStandardized 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
SUCATCategory for Substance UseChar*Grouping QualifierUsed to define a category of related records. Examples: "TOBACCO", "ALCOHOL", or "CAFFEINE".Perm
SUSCATSubcategory for Substance UseChar*Grouping QualifierA further categorization of substance use. Examples: "CIGARS", "CIGARETTES", "BEER", "WINE".Perm
SUPRESPSU Pre-SpecifiedChar(NY)Variable QualifierUsed to indicate whether ("Y"/null) information about the use of a specific substance was solicited on the CRF.Perm
SUOCCURSU OccurrenceChar(NY)Record QualifierWhen the use of specific substances is solicited, SUOCCUR is used to indicate whether ("Y"/"N") a particular prespecified substance was used. Values are null for substances not specifically solicited.Perm
SUSTATCompletion StatusChar(ND)Record QualifierWhen the use of prespecified substances is solicited, the completion status indicates that there was no response to the question about the prespecified substance. When there is no prespecified list on the CRF, then the completion status indicates that substance use was not assessed for the subject.Perm
SUREASNDReason Substance Use Not CollectedChar
Record QualifierDescribes the reason substance use was not collected. Used in conjunction with SUSTAT when value of SUSTAT is "NOT DONE".Perm
SUCLASSubstance Use ClassChar*Variable QualifierSubstance 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
SUCLASCDSubstance Use Class CodeChar*Variable QualifierCode corresponding to SUCLAS. May be obtained from coding.Perm
SUDOSESubstance Use ConsumptionNum
Record QualifierAmount of SUTRT consumed. Not populated if SUDOSTXT is populated.Perm
SUDOSTXTSubstance Use Consumption TextChar
Record QualifierSubstance use consumption amounts or a range of consumption information collected in text form. Not populated if SUDOSE is populated.Perm
SUDOSUConsumption UnitsChar(UNIT)Variable Qualifier

Units for SUDOSE, SUDOSTOT, or SUDOSTXT. Examples: "oz", "CIGARETTE", "PACK", "g".

Perm
SUDOSFRMDose FormChar(FRM)Variable QualifierDose form for SUTRT. Examples: "INJECTABLE", "LIQUID", "POWDER".Perm
SUDOSFRQUse Frequency Per IntervalChar(FREQ)Variable QualifierUsually expressed as the number of repeated administrations of SUDOSE within a specific time period. Example: "Q24H" (every day).Perm
SUDOSTOTTotal Daily ConsumptionNum
Record QualifierTotal daily use of SUTRT using the units in SUDOSU. Used when dosing is collected as total daily dose. If a 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
SUROUTERoute of AdministrationChar(ROUTE)Variable QualifierRoute of administration for SUTRT. Examples: "ORAL", "INTRAVENOUS".Perm
TAETORDPlanned Order of Element within ArmNum
TimingNumber 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
EPOCHEpochChar(EPOCH)TimingEpoch associated with the start date/time of the substance use. Null for substances that started before study participation.Perm
SUSTDTCStart Date/Time of Substance UseCharISO 8601 datetime or intervalTimingStart date/time of the substance use represented in ISO 8601 character format.Perm
SUENDTCEnd Date/Time of Substance UseCharISO 8601 datetime or intervalTimingEnd date/time of the substance use represented in ISO 8601 character format.Perm
SUSTDYStudy Day of Start of Substance UseNum
TimingStudy day of start of substance use relative to the sponsor-defined RFSTDTC.Perm
SUENDYStudy Day of End of Substance UseNum
TimingStudy day of end of substance use relative to the sponsor-defined RFSTDTC.Perm
SUDURDuration of Substance UseCharISO 8601 durationTimingCollected 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
SUSTRFStart Relative to Reference PeriodChar(STENRF)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
SUENRFEnd Relative to Reference PeriodChar(STENRF)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
SUSTRTPTStart Relative to Reference Time PointChar(STENRF)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
SUSTTPTStart Reference Time PointChar
TimingDescription or date/time in ISO 8601 character format of the reference point referred to by SUSTRTPT. Examples: "2003-12-15", "VISIT 1".Perm
SUENRTPTEnd Relative to Reference Time PointChar(STENRF)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
SUENTPTEnd Reference Time PointChar
TimingDescription or date/time in ISO 8601 character format of the reference point referred to by SUENRTPT. Examples: "2003-12-25", "VISIT 2".Perm
