Top Clinical Data Management Interview Questions and Answers for Freshers

1. What is Clinical Data Management (CDM)?

Clinical Data Management is the process of collecting, cleaning, and managing data generated from clinical trials. This ensures the data is accurate, reliable, and compliant with regulatory standards, playing a crucial role in the development of new medical treatments.

2. What are the key phases of a clinical trial?

Clinical trials are divided into four phases:

• Phase I: Tests safety in a small group.
• Phase II: Evaluates effectiveness on a larger group.
• Phase III: Confirms effectiveness on a large scale.
• Phase IV: Monitors long-term effects post-approval.

3. What is a Case Report Form (CRF)?

A Case Report Form is a standardized document used in clinical trials to collect patient data. It can be electronic or paper-based.

4. What is a discrepancy in CDM and how do you resolve it?

A discrepancy refers to any inconsistency found in the data. It is resolved by querying the site for clarification, verifying the corrected data, and ensuring the database is updated accordingly.

5. What is 21 CFR Part 11?

21 CFR Part 11 is a regulation by the FDA that sets the standards for electronic records and electronic signatures in clinical trials. It ensures that digital data is reliable and equivalent to paper records.

6. How do you ensure data accuracy during a clinical trial?

Data accuracy is ensured through rigorous quality control processes, including data validation, verification of entries, discrepancy management, and regular audits.

7. What is an audit trail in CDM?

An audit trail is a record that tracks changes made to the clinical data, including who made the changes, when, and why. It ensures transparency and data integrity throughout the trial.

8. What is database lock?

Database lock is the final stage in CDM, where the clinical data is reviewed, verified, and no further changes are allowed. This ensures that the data is ready for analysis.

9. How do you manage missing or incomplete data?

Missing data is managed through queries to the research site or statistical methods like data imputation. It’s essential to follow predefined procedures to ensure data integrity.

10. What are common data validation techniques used in CDM?

Data validation techniques include range checks, logic checks, and cross-field consistency checks. These methods help ensure that the data collected adheres to predefined criteria.
