Of course, when we review a qualifying exam, we can't be closed-door. We should pay attention to the new policies and information related to the test CCDM certification. For the convenience of the users, the CCDM test materials will be updated on the homepage and timely update the information related to the qualification examination. Annual qualification examination, although content broadly may be the same, but as the policy of each year, the corresponding examination pattern grading standards and hot spots will be changed, the CCDM Test Prep can help users to spend the least time to pass the exam.

SCDM Certified Clinical Data Manager Sample Questions (Q131-Q136):

NEW QUESTION # 131
Which data are needed to monitor site variability in eligibility screening?

A. Number of subjects enrolled
B. Number of subjects screened and number of subjects enrolled
C. Number of sites with high enrollment
D. Number of sites with low enrollment

Answer: B

Explanation:
To monitor site variability in eligibility screening, you must analyze the number of subjects screened versus the number of subjects enrolled at each site. This allows identification of sites that are over- or under-screening relative to their enrollment yield.
The GCDMP (Chapter: Data Quality Assurance and Metrics) emphasizes that screening-to-enrollment ratios are critical indicators of protocol compliance and data quality. Sites with unusually low conversion rates may have unclear understanding of inclusion/exclusion criteria, requiring targeted training or monitoring.
Other options (A, C, D) provide enrollment metrics but do not reveal screening efficiency or variability, which depend on both screening and enrollment data.
Thus, option B correctly identifies the data necessary for monitoring eligibility screening performance across sites.

NEW QUESTION # 132
Which of the following actions is particularly important in merging data from different trials?

A. Use of a common adverse event dictionary
B. Use of a common software platform
C. Enrollment of investigative sites with similar patient populations
D. Exclusion of studies that use a cross-over design

Answer: A

Explanation:
When merging data from different clinical trials, the use of a common adverse event (AE) dictionary (such as MedDRA or WHO Drug) is essential to ensure consistency and comparability across datasets.
According to the GCDMP (Chapter: Standards and Data Mapping) and CDISC SDTM Implementation Guide, data integration across studies requires standardized terminology for adverse events, medications, and clinical outcomes. Using the same AE dictionary ensures that similar terms are coded consistently, allowing accurate cross-study analysis, pooled summaries, and safety reporting.
A shared software platform (option A) is not necessary if data are mapped to standard formats (e.g., CDISC SDTM). Patient population similarity (option B) affects interpretation but not technical data merging. Study design differences (option C) may influence statistical analysis but not data integration mechanics.
Therefore, Option D - Use of a common adverse event dictionary - is the correct and most critical action for consistent multi-study data integration.

NEW QUESTION # 133
Every database lock should follow documented approval of which stakeholders?

A. Clinical/Scientific Representative, Data Manager
B. Clinical/Scientific Representative, Biostatistician, Programmer
C. Clinical/Scientific Representative, Data Manager, Biostatistician
D. Clinical/Scientific Representative, Biostatistician

Answer: C

Explanation:
According to the Good Clinical Data Management Practices (GCDMP), the database lock (DBL) process signifies the formal closure of the clinical trial database, ensuring that no further changes can be made to the data before statistical analysis. This process must be documented, controlled, and approved by key study stakeholders to ensure data accuracy, completeness, and readiness for analysis.
The GCDMP specifies that database lock should occur only after all data cleaning, discrepancy resolution, and reconciliation activities are complete. The lock authorization typically requires the approval of the Clinical/Scientific Representative (to confirm clinical completeness), the Data Manager (to confirm data integrity and query closure), and the Biostatistician (to confirm readiness for statistical analysis).
This tri-party approval ensures that the database reflects final, verified data consistent with the clinical protocol, and that the statistical analysis dataset derived from the database is accurate and auditable. The approval process is documented via a Database Lock Authorization Form or Sign-off Log, which becomes part of the permanent trial master file (TMF).

NEW QUESTION # 134
In a study, data are key entered by one person after which a second person enters the data without knowledge of or seeing the values entered by the first. The second person is notified during entry if an entered value differs from first entry and the second person's decision is retained as the correct value. Which type of entry is being used?

A. Manual review
B. Single entry
C. Blind verification
D. Third-party compare

Answer: C

Explanation:
The described process is Blind Verification, also known as double data entry with blind verification. In this method, two independent operators enter the same data. The second operator is blinded to the first entry to avoid bias. When discrepancies arise, the system flags them for review, and the second entry (or an adjudicated value) is retained as the correct one.
According to GCDMP (Chapter: Data Entry and Data Tracking), blind double data entry is used primarily in paper-based studies to minimize transcription errors and ensure data accuracy.
Single entry (D): Only one operator enters data.
Manual review (B): Involves post-entry checking, not during entry.
Third-party compare (C): Used for reconciling external data sources, not CRF data.
Hence, option A (Blind verification) is the correct and CCDM-defined process.

NEW QUESTION # 135
If database auditing is used for data quality control during a study, which is the optimal timing of the audits?

A. After the first few cases have been entered
B. Periodically throughout the study
C. Immediately following database lock
D. A week or two before database lock

Answer: B

Explanation:
Database audits are conducted to ensure ongoing data accuracy, completeness, and compliance throughout the lifecycle of a clinical trial. According to the Good Clinical Data Management Practices (GCDMP, Chapter: Data Quality Assurance and Control), quality audits are most effective when performed periodically during study conduct, rather than waiting until study completion.
Performing audits periodically allows early detection of data entry errors, protocol deviations, and system inconsistencies, thereby reducing the risk of large-scale data issues before database lock. This proactive approach aligns with risk-based quality management principles outlined in ICH E6(R2) and ensures corrective actions are implemented in real time.
Options A and B represent reactive quality control, which occurs too late to prevent data issues. Option C (after first few cases) provides initial validation but does not ensure continuous oversight.
Therefore, option D - "Periodically throughout the study" - represents the optimal and compliant timing for quality audits of the database.
