A Clinical Data Manager is responsible for overseeing the entire data management process in a clinical trial. This includes designing data management plans (DMPs), developing and maintaining clinical trial databases, ensuring data quality through validation checks, resolving discrepancies, and preparing data for analysis. The Clinical Data Manager works closely with other team members to ensure that the data collected is accurate and compliant with regulatory standards​.

3. What is a Data Management Plan (DMP)?

A Data Management Plan (DMP) is a document that outlines the procedures, tasks, and milestones related to data management throughout a clinical trial. It covers aspects such as data collection methods, data integration, storage and backup procedures, data security, and regulatory compliance. The DMP serves as a roadmap for managing data and is essential for ensuring that all team members are aligned on how data will be handled during the trial​.

4. What is an electronic Case Report Form (eCRF)?

An electronic Case Report Form (eCRF) is a digital questionnaire used to collect data from study participants in a clinical trial. The eCRF is designed based on the study protocol and is a crucial tool for capturing accurate and consistent data. The data entered into the eCRF is typically validated and stored in a clinical trial database for further analysis. The design and structure of eCRFs are guided by industry standards such as CDISC to ensure uniformity and ease of data sharing across studies​.

5. How does data validation work in CDM?

Data validation in Clinical Data Management involves a series of checks to ensure that the data collected is accurate, consistent, and complete.
