CCRA Data Management and Source Document Verification 2

Question 1

The 'data lock' in a clinical trial refers to:

Accepted Answer

The point at which the database is closed to further changes in preparation for statistical analysis

Answer

Database lock is the formal process of freezing the clinical database after all data queries are resolved, confirming the dataset is complete and ready for unblinded statistical analysis.

Question 2

What percentage of SDV is typically used in a traditional 100% SDV monitoring approach?

Accepted Answer

100% of all CRF data compared to source documents

Answer

Traditional monitoring required 100% SDV of all CRF data against source documents, though modern risk-based approaches allow reduced SDV targeting critical data only.

Question 3

Which regulatory guidance specifically supports a reduced and risk-adapted approach to source data verification?

Accepted Answer

FDA Guidance for Industry: Oversight of Clinical Investigations — A Risk-Based Approach to Monitoring (2013)

Answer

The FDA's 2013 RBM guidance explicitly endorses a risk-based approach to monitoring including targeted SDV focused on critical data rather than 100% verification of all data.

Question 4

In clinical data management, 'edit checks' are used to:

Accepted Answer

Validate data entries against predefined rules to detect out-of-range values, missing data, or logical inconsistencies

Answer

Edit checks (or validation rules) are programmed into EDC systems to flag data that is missing, illogical, or outside expected ranges, prompting review or generating queries.

Question 5

A 'data management plan' (DMP) in a clinical trial typically includes:

Accepted Answer

Database design, data collection procedures, validation rules, and quality control processes for the trial's data

Answer

The DMP outlines how data will be collected, validated, cleaned, and managed throughout the trial, covering EDC configuration, query management, coding, and database lock procedures.
