Tobacco Device Events (PI) Example 1

This is an example of a study where the sponsor collected events associated with the operation of the electronic cigarette device. Events not specifically associated with the device should not be represented in this domain.

The associated SDTM datasets for the data collected above are provided below. The Tobacco Product Identifier (TO) domain is a study reference dataset that provides a mechanism for uniquely identifying a tobacco product. Only one product was of interest in the study. Note this identifier also describes any device use by the subject to deliver the tobacco.

Sponsor may use standardized or dictionary-derived text for the description of a device event/problem. CDISC does not provide information on what standardized or dictionary-derived text should be used.

This sponsor decided to use the International Medical Device Regulators Forum (IMDRF) document “IMDRF Terminologies for Categorized Adverse Event Reporting (AER): Terms, Terminology Structure and Codes. Annex A ( 2022) provide the medical problem codes. The name and version of the dictionary used to map terms must be provided in a Define.XML ExternalCodeList element. PIDECODE was the Level 3 IMDRF term. The coding of the problems/events may be done using other methods/dictionaries.

( NOTE: Meta Example to be confirmed with RM.

This example illustrates how the coding information for a product issue might be represented. The parent domain (RDOMAIN) is PI, and IDVAR is PISEQ. QNAM holds the name of the supplemental qualifier variable being defined. This only shows the data for subject 2029. The data recorded in QVAL applies to the subject’s records, where IDVAR (PISEQ) equals the value specified in IDVARVAL.
