These product issues and events are represented in the Tobacco Product Events and Malfunctions Domain (EM).  Events not specifically associated with the product device should not be represented in this EM domain.     

The sponsor used a 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). 

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. EMDECOD was the Level 3 IMDRF term. Non-standard variables were used to represent the various coding level variables defined in the dictionary.

Below is the dataset, SUPPEM, used to represent the non-standad varibables used for coding the issue or event. The parent domain (RDOMAIN) is EM, and IDVAR is EMSEQ. 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 (EMSEQ) equals the value specified in IDVARVAL.
