CCDM Data Standards & Database Design 3

Question 1

In ADaM dataset design, what is the key distinguishing feature of a BDS (Basic Data Structure) dataset?

Accepted Answer

One or more records per subject per analysis parameter per timepoint

Answer

ADaM BDS datasets have one or more records per subject per analysis parameter per timepoint, supporting a wide variety of statistical analyses.

Question 2

What is the purpose of the SUPPQUAL (Supplemental Qualifiers) dataset in SDTM?

Accepted Answer

To hold additional non-standard variables that cannot be accommodated in the parent domain

Answer

SUPPQUAL datasets store additional qualifier variables for a parent domain when standard domain variables are insufficient.

Question 3

When designing a database edit check, what is the difference between a 'range check' and a 'cross-field check'?

Accepted Answer

Range checks verify a single value against defined limits; cross-field checks compare two or more fields for consistency

Answer

A range check validates that a single field value falls within predefined acceptable bounds, while a cross-field check verifies logical relationships between multiple fields.

Question 4

Which MedDRA hierarchy level is used as the primary endpoint coding level in most adverse event analyses?

Accepted Answer

Preferred Term (PT)

Answer

The Preferred Term (PT) is the primary level for MedDRA coding in adverse event analyses, as it represents a distinct medical concept.

Question 5

A study team finds that the same adverse event is coded differently across two clinical sites. Which root cause is MOST likely?

Accepted Answer

Inconsistent application of coding dictionaries or versions

Answer

Inconsistent coding occurs when different sites use different versions of MedDRA or apply coding conventions differently without centralized oversight.
