SCDM Data Reconciliation and Validation

Question 1

What is the primary purpose of data reconciliation in clinical data management?

Accepted Answer

To ensure consistency and completeness of data across multiple sources

Answer

To generate statistical reports for regulatory submission

Answer

To train data entry personnel on EDC systems

Answer

To archive completed case report forms

Question 2

During external data reconciliation, a discrepancy is found between the EDC system and the central lab data. What is the appropriate first step?

Accepted Answer

Investigate the source of the discrepancy using original source documents

Answer

Immediately correct the EDC record to match the lab data

Answer

Delete the discrepant record from both systems

Answer

Report the discrepancy to the FDA without further review

Question 3

Which type of validation check verifies that a date entered in a CRF falls within the acceptable range of the study period?

Accepted Answer

Range check

Answer

Cross-form validation

Answer

Consistency check

Answer

Completeness check

Question 4

What does a 'discrepancy management' process in clinical data management primarily involve?

Accepted Answer

Identifying, documenting, resolving, and closing data queries

Answer

Eliminating all data queries before study start

Answer

Randomizing subjects to treatment arms

Answer

Archiving all CRFs after database lock

Question 5

In clinical data management, a 'hard edit' (or hard stop) in an EDC system means:

Accepted Answer

The system prevents data entry from being saved until the error is corrected

Answer

The system allows data entry to proceed after acknowledging a warning

Answer

The system automatically corrects the data without user intervention

Answer

The system sends a query to the site monitor for review

Question 6

Lab data reconciliation typically requires comparing EDC-entered lab values against which reference?

Accepted Answer

Listings or data transfers from the central or local laboratory

Answer

Investigator brochure

Answer

Protocol-specified statistical analysis plan

Answer

IRB approval documentation

Question 7

Which metric is commonly used to measure the quality of data during validation activities?

Accepted Answer

Error rate (number of errors per 100 fields entered)

Answer

Protocol deviation rate

Answer

Patient enrollment velocity

Answer

Investigator site activation timeline
