CCDM Electronic Data Capture 4 — Questions and Answers
Question 1: In risk-based monitoring (RBM), EDC data is used to identify 'Key Risk Indicators (KRIs).' What do KRIs primarily help sponsors do?
- Automate randomization procedures
- Prioritize monitoring resources toward sites with higher data quality risks (Correct answer)
- Generate automated adverse event reports
- Assign subjects to treatment arms
Correct answer: Prioritize monitoring resources toward sites with higher data quality risks
KRIs derived from EDC data help sponsors identify sites or data patterns that pose elevated risk, allowing targeted allocation of monitoring resources.
Question 2: A clinical data manager discovers that a site has been entering data weeks after events occurred. This issue relates to which data quality dimension?
- Accuracy
- Timeliness (Correct answer)
- Completeness
- Consistency
Correct answer: Timeliness
Timeliness refers to the requirement that data be entered promptly after the event; late entry can affect data integrity and regulatory compliance.
Question 3: Which type of EDC system integration allows lab results to be automatically imported into the eCRF without manual re-entry?
- EDC-to-IVRS integration
- Laboratory data transfer or HL7 interface (Correct answer)
- RTSM integration
- CTMS synchronization
Correct answer: Laboratory data transfer or HL7 interface
Laboratory data transfers using standards like HL7 or flat-file interfaces allow lab results to flow directly into the EDC system, reducing transcription errors.
Question 4: During EDC system validation, what document formally captures the tests performed, expected results, actual results, and pass/fail status?
- Protocol amendment
- Validation test script or test execution record (Correct answer)
- Informed consent form
- Data management plan
Correct answer: Validation test script or test execution record
Validation test scripts document each test case with expected and actual outcomes to provide evidence that the system performs its intended functions.
Question 5: What is the role of an Independent Data Monitoring Committee (IDMC) in relation to EDC data?
- To build and configure the EDC system
- To periodically review unblinded accumulating safety and efficacy data to recommend trial continuation or stopping (Correct answer)
- To resolve data queries at the site level
- To perform database lock procedures
Correct answer: To periodically review unblinded accumulating safety and efficacy data to recommend trial continuation or stopping
The IDMC reviews interim unblinded data from the EDC to assess benefit-risk and may recommend stopping or modifying the trial based on safety or futility.
Question 6: Which CDISC standard is specifically designed for the structure of clinical trial data submitted to regulatory agencies, and is closely linked to how EDC data must ultimately be organized?
- CDASH (Clinical Data Acquisition Standards Harmonization)
- SDTM (Study Data Tabulation Model) (Correct answer)
- ADaM (Analysis Data Model)
- ODM (Operational Data Model)
Correct answer: SDTM (Study Data Tabulation Model)
SDTM defines the standard structure for organizing and submitting clinical trial data to the FDA and other regulatory agencies.
Question 7: A sponsor requires that sites obtain electronic signatures from investigators to confirm data accuracy. Under 21 CFR Part 11, which of the following must accompany an electronic signature?
- A wet-ink countersignature
- The full name of the signer, date and time, and the meaning of the signature (Correct answer)
- A notarized certificate
- A paper printout of the signed record
Correct answer: The full name of the signer, date and time, and the meaning of the signature
21 CFR Part 11 requires that electronic signatures include the signer's printed name, the date and time signed, and the meaning (e.g., approval, authorship).
