CCDM Clinical Data Collection & Management 2

Question 1

Which data collection method is most appropriate when source data must remain at the investigative site but needs to be available to the sponsor?

Accepted Answer

Remote data entry via EDC with audit trail

Answer

Remote data entry via EDC allows sponsors to access data in real time while source data remains at the site, with a full audit trail maintaining data integrity.

Question 2

A site submits a query response that changes a previously reported SAE date. What is the data manager's primary concern?

Accepted Answer

Assessing whether the change affects regulatory reportability timelines

Answer

A changed SAE date may alter the 15-day or 7-day regulatory reporting clock, making assessment of reportability timelines the highest priority.

Question 3

What distinguishes a 'transcription error' from a 'data entry error' in clinical data management?

Accepted Answer

A transcription error occurs when copying from source to CRF; a data entry error occurs when entering CRF data into a database

Answer

A transcription error happens at the source-to-CRF step, while a data entry error happens at the CRF-to-database step, making them distinct in origin and prevention strategy.

Question 4

In a blinded clinical trial, which role is typically permitted to access unblinded randomization data during the study?

Accepted Answer

The unblinded pharmacovigilance team for SAE causality assessment

Answer

An unblinded pharmacovigilance team may access randomization codes to assess SAE causality, but the rest of the study team remains blinded to protect data integrity.

Question 5

Which metric is most useful for tracking the efficiency of the data query resolution process?

Accepted Answer

Average query cycle time from issuance to closure

Answer

Average query cycle time measures how quickly sites respond to and close queries, directly reflecting the efficiency of the data cleaning process.
