  • Securing and backing up clinical data – Encrypted databases, access controls and regular back-ups prevent data loss and breaches


With robust data management strategies, clinical trials can maintain regulatory-compliant, high-quality data for analysis and submissions.

Monitoring Clinical Trials in Data Management in Clinical Research

Clinical trial monitoring is an important oversight activity that helps ensure study data quality. Monitors perform on-site and remote monitoring to verify the following aspects related to data management:

  • Accuracy of data against source documents – Monitors verify if data captured in CRFs matches medical records, lab reports, etc. This identifies transcription errors.
  • Protocol and process compliance – Monitors check if site processes like data entry, corrections, coding, archiving, etc. follow the approved protocol SOPs.
  • Data quality and completeness – By reviewing CRFs and databases, monitors identify any discrepancies, inconsistencies, missing data or protocol deviations to be queried.
  • Adverse event data – Monitors verify if adverse events are correctly reported within stipulated timelines and coded as per standards.
  • Use of certified systems – Monitors check validity of system certifications and access controls on EDC clinical trials, eCOA, CTMS, etc. to ensure compliance.
  • Data management plan implementation – Whether the actual trial conduct reflects the planned methodology in the data management plan is reviewed.
  • Resolution of queries – Monitors check if outstanding data queries are resolved and changes documented through audit trails.

Ongoing communication between monitors and data managers helps quickly identify and resolve data issues that could compromise clinical trial integrity.

The Role of Regulatory Affairs Consultants in Data Management in Clinical Research

Regulatory consultants are invaluable in guiding data management practices for clinical trials. Some key roles include:
