The Data Manager (DM) plays a critical role in maintaining transparent communication with the clinical study team regarding data quality and study progress. One of the most essential metrics regularly reported by the DM is the percentage of data entered and cleaned.
According to the Good Clinical Data Management Practices (GCDMP, Chapter: Communication and Study Reporting), these metrics provide insight into study status, data readiness for interim analysis, and timeline predictability for database lock. Regular communication includes:
Percent of CRFs entered and verified
Percent of queries resolved
Outstanding data issues or missing pages
Other options fall outside the Data Manager's direct responsibility:
A (Enrollment) is typically reported by clinical operations.
B (Staffing changes) are handled by site management.
D (Safety events) are communicated by the safety/pharmacovigilance team.
Thus, option C correctly reflects the Data Manager's responsibility for ongoing study communication.
