Types of Monitoring Visits


Pre-Study Visit

A pre-study visit takes place after a potential PI indicates interest in a specific clinical trial. The purpose of this visit is to determine the site’s ability to conduct the study. The CRA evaluates:

  • PI responsibilities and qualifications
  • Study objectives and procedures
  • Site facilities and equipment
  • Staff qualifications
Visitors speaking with reception staff at Convex

Initiation Visit

Once the PI agrees to participate and all regulatory approvals are in place, an initiation visit verifies that the site understands:

  • Study overview and eligibility criteria
  • GCP guidelines and regulations
  • Data forms and recording

Close-Out Visit

The final visit ensures proper completion of all study activities:

  • Complete outstanding data and queries
