Question 1

What is a 'query' in the context of EDC data management?

Accepted Answer

A request for clarification or correction of a data discrepancy identified in the EDC system

Answer

A SQL command used to extract data from the clinical database

Answer

A regulatory agency's request for additional study information

Answer

A site's request to access an additional subject's records

Question 2

What is the purpose of 'central data monitoring' in modern clinical trials?

Accepted Answer

To use statistical and analytical techniques to remotely evaluate data quality and site performance

Answer

To conduct on-site monitoring visits at every participating center

Answer

To manage the EDC system configuration centrally

Answer

To review SAEs reported by all sites in a central repository

Question 3

What is an 'unscheduled visit' in EDC data collection?

Accepted Answer

A visit that occurs outside the protocol-defined schedule, typically for safety reasons

Answer

A visit where the subject arrives before the protocol window

Answer

A visit conducted by a monitor rather than a clinical staff member

Answer

A visit recorded only in source documents and not in the EDC

Question 4

What is the significance of 'data entry latency' in clinical EDC systems?

Accepted Answer

The time between a clinical event occurring and when data is entered into the EDC, which affects data quality and timeliness

Answer

The system response time when a user submits a CRF page

Answer

The delay between database lock and statistical analysis

Answer

The time required to transmit data from the site to the central server

Question 5

In EDC design, what is a 'conditional field' (or dynamic field)?

Accepted Answer

A field that only becomes visible or required based on a response to a prior question

Answer

A field that has been conditionally approved by the sponsor

Answer

A field that is optional for some sites and mandatory for others

Answer

A field that changes its label based on subject age

Question 6

What is 'discrepancy management' in clinical data management?

Accepted Answer

The systematic process of identifying, querying, resolving, and tracking data inconsistencies in the database

Answer

The process of reconciling subject counts between sites and the central database

Answer

The review of protocol deviations detected during monitoring visits

Answer

The management of conflicting safety signals identified by the DSMB
