This is an example of a study where the sponsor collected issues and events associated with the operation of the electronic cigarette device . Events not specifically associated with the device should not be represented in this domain.  and any adverse events that a subject experienced as a result of the product issue or event.   

This is an example of a CRF used to collect this data. 

The associated SDTM datasets for the data collected above are provided below. The Tobacco Product Identifier (TO) domain is a dataset that which provides a mechanism for uniquely identifying a tobacco product was used. Only  Only one product was of interest in the study. 

The sponsor collected information on any issues or events  associated with the ENDS device. These issues and problems are  These product issues and events are represented in the Product Issues and Events Domain (PI).  Events not specifically associated with the device should not be represented in this PI domain.     

A The sponsor may use used standardized or dictionary-derived text for the description of an issue or events. CDISC does not provide information on what standardized or dictionary-derived text should be used (if any) . 

In this example, the The 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) provides 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. Non-standard variables were used to represent the various coding level variables defined in the dictionary. The coding of issues or events may be done using other dictionaries.

Example SUPPPI  Variable Metadata

...

The PI dataset is shown below; 

Below is the dataset, SUPPPI, used to represent the non-standad varibables  varibables used for coding the issue or event.   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. 

Subject IN this study, subject 3067 had an AE associated with the battery problem. This was reported in the AE dataset. Not all variables are shown for brevity.  

The RELREC dataset was used to record the relationship between the Product Issues and Events in (PI) dataset and any reported AE represented in the AE dataset.
