TO BE REMOVED ; ISSUES TO BE DISCUSSED  

1: Should  we use SC for all details question about usage and quitting. or FASU....    (e.g.  longest period of abstinence in the past year, Have you attempted to quit smoking, Number of previous attempts to quit smoking, Used patches) , Years of regular smokeless tobacco. (A type of tobacco that is not smoked or burned.) It may be used as chewing tobacco or moist snuff, or inhaled through the nose as dry snuff.    

2. 4, Is DOSFRM used to identify  Chewing tobacco, snuff, etc. Is this then nicotine as the TRT and the route is ORAL  SNUFF is inhalation.   


INFORMATION ABOUT AGE Started smoking, AVERAGE CIGATEERS USED PER DAY,  USED SMKELESS TOBACCO, E-Cigartees etc. 

Types of tobacco use Cigarette,Cigars,Smokeless Tobacco,Pipe Tobacco,Nicotine Vaping    Collected with Check all that appy in CDASH. 


The Interventions domains in SDTM capture investigational, therapeutic, and other treatments that are administered to the subject (with some actual or expected physiological effect) either as specified by the study protocol (e.g., exposure to study product  coincident with the study assessment period (e.g., concomitant medications), or self‑administered by the subject (e.g., use of alcohol, tobacco, or caffeine).

Recreational drugs are chemical substances taken for enjoyment, or leisure purposes, rather than for medical reasons. They are often drugs that are misused or abused or drugs self-administered by the subject.  To support standardization, CDISC defined a Substance Use (SU) domain. This domain is used to represent intervention that are Substance Use (SU )interventions used for non-medical purposes and often maybe harmful to the individual or others. These include alcohol, marijuana and tobacco.  

Other domains have been established to record other types of interventions. Interventions administered to the subject coincident with the study assessment period are referred to as concomitant medications and represented in the SDTM Concomitant/Prior Medications (CM) domain and interventions administered as protocol-specified study products are represented  in the Exposure (EX) and Exposure as Collected (EC) domains..

In clinical trials studying tobacco products, tobacco products being used for non-medical purpose will be represented in the SU domain. However, products being used to reduce the usage of these self-administered tobacco products, will be considered either concomitant medications, or the product under study. 


Example

This is the SDTM dataset used to represent the above collected data. The applicant populated SUPRESP="Y" for all substances specified in the drop-down list on the CRF. Other substances were not considered prespecified.   

Row 1:Shows that the subject was using cigarettes before the baseline visit and was expected to continue to use cigarettes after the baseline visit, The baseline visit occurred on 2006-01-01. This is represented using SUSTTPT, SUSTRTPT, SUENTPT and SUENRTPT. SUPRESP is used to indicate that the use of cigarettes was solicited on the CRF.
Row 2:Shows the subject uses marijuana starting in 2002 and stopped using it on the day of the baseline visit. SUPRESP is used to indicate that the use of marijuana was solicited on the CRF.
Row 3:Subject 1234006 is a former smoker. The date this subject began smoking is unknown, but it was sometime before the assessment date; this is shown by the values of SUSTTPT and SUSTRTPT. The end date of smoking was collected, so SUENTPT and SUENRTPT are not populated. Instead, the end date is in SUENDTC.
Row 4:Shows the subjects had missing data for the usage of recreational products; this is indicated by SUSTAT = "NOT DONE". The reason is in SUREASND.
